Description

' United States Patent Short CONTROLLER FOR AUTOMATIC PINSETTER Primary ExaminerAnton O. Oechsle Attorney, Agent, or Firm.lohn H. Widdowson June 17, 1975 1 1 ABSTRACT A controller for a bowling pinsetter has an electric motor with a clutch and a raisable and lowerable deck to receive pins and place them on a lane. A first switch is operable by the deck. A second switch is operable by a clutch linkage on the electric motor. The switches are connected in parallel to control on and off operation of the motor so it will operate when either switch is closed and it will not operate when both switches are open. In a second embodiment, a delay relay is associated with the second switch in such manner as to maintain the motor in operation for a predetermined time after the second switch is closed. In both embodiments the motor is maintained in operation for a period of time sufficient to enable the pin distribution apparatus driven by the motor to perform the pin handling operations required of it.

12 Claims, 7 Drawing Figures CONTROLLER FOR AUTOMATIC PINSETTER BACKGROUND OF THE INVENTION The invention is related to automatic bowling pinsetters and particularly controllers therefor which terminate operation of an electric motor in the pin distribution system thereof during periods when it is not necessary for the motor to operate. In the prior art automatic bowling pinsetters of the type for which this invention is designed have a pin distribution system with an electric motor and a clutch. This portion of the mechanism is operable to pass the bowling pins from a pin gathering portion of the apparatus into a deck assembly that is raisable and lowerable to receive bowling pins and place them on the end of the bowling lane. In such pinsetters the motor normally runs continuously when the machine is turned on for operation and due to the complicated nature of the machines, many of the movable parts thereof are kept in motion. The electric motor is connected to the clutch of a transmission assembly which functions to cycle a portion of the machine through the steps of removing pins from the end of the bowling alley and placing them in the deck for resetting. The motor powers a pin elevator which picks up the bowling pins and raises them to a position where they are taken by a conveyor, also powered from the electric motor, to a turret assembly, also powered by the electric motor, where they pass into the deck, which is powered by the motor through the transmission assembly. Prior art controllers are known which govern the operating time of the electric motor so that it operates for a predetermined certain time period which allows a more than substantial time for the ma chine to complete its operation then turns the motor off. This particular type of prior art controller causes the electric motor to operate longer than actually necessary because it lets the motor operate or idle once the deck has been loaded with bowling pins to be placed on the bowling lane in the next cycle. An additional disadvantage to this particular prior art controller is that during league play the bowlers take turns quite rapidly, thus the electric motor may not necessarily reach the end of its operating time period or would do so very shortly before the next operating cycle so the motor runs substantially continuously and there is little or no improvement in reducing unnecessary operating time for the motor or wear on the mechanism of the machine.

SUMMARY OF THE INVENTION In a specific embodiment, (1), a controller for auto matic pinsetters includes a first switch assembly electrically connected to the pin distribution system drive motor and operable by motion of the deck assembly, and a second switch assembly electrically connected in parallel with the first switch assembly and operable by the clutch mechanism of the pin distribution systems drive motor. The switch assemblies are connected with the electric motor so that the electric motor will be operated when either of the switches are closed and will be stopped when both of the switch assemblies are open. Before the first ball is thrown, the switches are open, ten pins are on the end of the bowling lane, and the machine is stopped waiting for the bowler to deliver the ball. When the first ball is delivered, the clutch is engaged when the ball impacts at the pinsetter and the second switch assembly is actuated by engagement of the clutch, thus starting the motor. The first switch closes when the deck assembly is lowered and opens when the deck assembly is full of pins. Either the first switch assembly or the second switch assembly stops operation of the motor depending upon the particular cycle in which the machine is operating. The switch assemblies are connected with a relay that is electrically connected to intermittently interrupt power normally continuously supplied to the electric motor when the pinsetter machine is turned on.

In a second specific embodiment, (2), of the controller of this invention, such is designed for use on pinsetter machines which have a shortened cycle time and therefore cannot be operated by the first described embodiment of the controller of this invention. The controller of this embodiment, (2), is designed to function generally similar to the first described embodiment, (l), and it includes a delay relay apparatus to extend operating time of the motor beyond the time when the clutch is disengaged in a first ball standing pin cycle of operation so that the machine will function properly in filling the deck and returning the deck to the proper position.

One object of this invention is to provide a controller for automatic pinsetters overcoming the aforementioned disadvantages of the prior art devices.

Still, one other object of this invention is to provide a controller for automatic pinsetters having switch assemblies which are connected with an operating motor of the pinsetter to control operation of the motor so it operates only during the time necessary for functioning of the machine and not during times when the pin dis tribution system is idle and the motor would otherwise idle and also idly operate a portion of the mechanism.

Still, one other object of this invention is to provide a controller for automatic pinsetters which is operable to minimize the operation of an electric motor used for powering several portions of the pinsetter mechanism to have the overall result of reducing unnecessary wear on the mechanism and substantially reduce the amount of electrical power necessary to operate the pinsetter machine.

Yet, another object of this invention is to provide a controller for automatic pinsetters which has a pair of switches and additionally including a timer in one embodiment of the invention, the switches being connected in a parallel relation and connected to a relay to intermittently interrupt electrical power to an electric motor of the pinsetter which operates a major portion of the pinsetter mechanism with one switch actuated when a deck assembly is needing additional bowling pins and the other switch actuated from a clutch which is engaged when the first ball is thrown and is released as the pin distribution system finishes an operation cycle.

Yet, another object of this invention is to provide a controller for automatic pinsetters which is attachable with a conventional and popular make of automatic bowling pinsetters in a kit-like form.

Various other objects, advantages and features of the invention will become apparent to those skilled in the art from the following discussion, taken in conjunction with the accompanying drawings, in which:

It is to be understood that such discussion and description is not to unduly limit the scope of the invention.

DESCRIPTION OF PREFERRED EMBODIMENTS The pinsetter controller of this invention is disclosed herein in two embodiments. One embodiment, (1), includes a pair of switches mounted with the pinsetter mechanism and a relay electrically connected with the motor to intermittently interrupt electrical power supplied to the motor. Another embodiment, (2), includes a pair of switches mounted on the pinsetter mechanism, a delay relay apparatus connected with one of the switches and a relay electrically connected with the other switch and the delay relay apparatus, and the motor to intermittently interrupt electrical power normally supplied to the motor.

Referring to the drawings in detail and in particular to FIGS. 1 and 5, such illustrates portions of a bowling pinsetter apparatus and portions of an embodiment, (l of the automatic pinsetter controller of this invention. The automatic pinsetter controller, (1), includes a pair of switches generally indicated at 10 and 12 mounted with the interlock system of the pinsetter, (generally indicated at 14 and shown partially in FIG. 1), and further including a control box 16 (shown in FIG. 5) and electrically connected with electric motor 18 which powers the pinsetters pin distribution system. FIG. 1 shows a portion of the interlock system and gearbox stop and start mechanism of a bowling pinsetter; this portion of the pinsetter apparatus which controls some of the stopping, starting and sequencing of the pinsetter so that during the cycle of operation of the machine the turret portion thereof and the deck portion thereof are moved at appropriate times during the operating cycle. FIG. 5 shows the electric motor 18 mounted on a support member 20 of the pinsetters frame. a pulley 22 is on the output drive shaft of the motor 18. The motor 18 furnishes power for the pinsetters pin distribution system, including driving a gearbox which in turn operates the turret and deck portions of the pinsetter, operating an elevator assembly and a conveyor assembly for moving the bowling pins from the place where they are removed from the end of the bowling lane to the turret which places the pins in the deck for resetting on the end of the bowling lane. The bowling pinsetter apparatus depicted in part in the drawings is a bowling pinsetter manufactured by the Brunswick Corporation of Chicago, Illinois. The Brunswick Corporation has manufactured several models of the pinsetter, the A-l A-2 and A-2 with jet back modification which in the identified pinsetter apparatus the motor 18 is connected in the electrical circuit of the machine to operate continuously when the machine is turned on for operation, thus the pin elevator and the bowling pin conveyors operate continuously whether or not bowling pins are being carried by them. The clutch assembly on the gearbox is used to engage and disengage the gearbox when it is needed in the operating cycles of the machine.

FIG. 2 shows the bowling pinsetter gearbox assembly, indicated generally at 26, with the second switch 12 of the controller mounted thereon. The gearbox 26 functions in the pinsetter to operate a rake that pulls bowling pins from the end of the bowling lane, to raise and lower the deck, and to index the turret for placing pins in the deck, and additionally it includes many components not necessary for the understanding of the operation of the controller of this invention and which will not be described. The gearbox 26 has a clutch 28 mounted on one end thereof. The clutch 28 has a clutch lever 29 movable for engaging and disengaging. A clutch release lever 30 and plunger lever 31 are supported on the gearbox at the same pivotal mount with the plunger lever 31 being hollow on its interior and having the clutch release lever 30 positionable therein but not connected. The clutch release lever 30 is connected with the end of the clutch lever 29 by a stop arm and it is connected with and moved by the interlock link 38 that is moved by the rear interlock cross shaft 39 of the interlock system 14 shown in FIG. 1. A clutch actuator link 32 is pivotally attached to the end of the plunger lever 31. The clutch actuator link 32 is slidably connected with the reset lever 33 by a pin. The clutch actuator link is hollow and encloses the clutch latch 34 with the pin of the reset lever 33 resiliently urged contacting an upper portion of the clutch latch 34. The clutch latch 34 is moved to release the clutch 28 at the start of a cycle. FIG. 2 shows the gearbox and associated apparatus of a model A-2 Brunswick Corporation pinsetter. A cycle solenoid 35 is mounted above the gearbox 26 is connected by a start bell crank 36 and short connection link 37 to the clutch latch 34. Retraction of the cycle solenoids slug is done at the start of a cycle when a ball impacts at the rear of the pinsetter, thus instantly causing the starter bell crank 36 to be rotated which pulls the clutch 34 from its resting position in the clutch actuatorlinnk 32 so that the clutch actuator link 32 moves upward, thus rotating the plunger lever 31 in a counterclockwise direction. At the proper time in the cycle, the cycle solenoid 35 is de-energized so that the bell crank 36 rotates clockwise letting the clutch latch 34 fall back into place in the clutch actuator link 32. In A-l models of the Brunswick pinsetter, the cycle solenoid 35 shown in FIG. 2 is not present and a mechanical linkage is provided to move the start bell crank 36 and release the clutch latch 34 upon ball impact. The switch 12 is mounted on a bracket 40 and it has an actuator arm 41 extending under a lower portion of the plunger lever 31. When the clutch 28 is released and the plunger lever 31 rotates counterclockwise, it permits the switch actuator arm 41 to raise and thereby close the contacts of the switch 12.

FIG. 1 shows portions of the interlock system 14 of the automatic bowling pinsetter with the switches and 12 positioned in their appropriate locations. The first switch 10 is mounted on a stationary portion of the pinsetter structure, and it is actuated by a lever as will be described hereinafter. The interlock system 14 includes portions not shown in FIG. 1 as such has been omitted as it is not necessary for the understanding of how the controller of this invention functions. The interlock system has a deck lift shaft 42 mounted transversely through the pinsetter machine and structurally connected with the deck for raising and lowering same. Structural connection between the deck lift shaft 42 and the deck is not shown, however, the deck moves up and down to detect the presence of pins on the bowling lane and to place new pins. The deck lift shaft 42 has a protrusion 44 thereon which is engaged by a hook latch 46 mounted on a shaft 48. The hook latch 46 is released from the protrusion 44 only when the deck is lowered to the floor setting new pins. The turret portion of the pinsetter includes a turret indexing cam 50 with a projection 52 extending therefrom at one point. A follower moving on the turret indexing cam is connected with a long link 54 which is connected to the rear interlock cross shaft 39 for movement thereof when the follower contacts the turret cam projection 52. A pin release lever 56 is mounted above the turret indexing cam 50. The turret interlock probe 58 is shown in position against the pin release lever 56. The interlock system 14 has what is called a 180 stop interlock which is a control on the gearbox apparatus which will enable the clutch 28 to be released thereby stop ping indexing of the turret in the event that pins are not available for placing in the deck. As the pinsetterr approaches the 180 position, the clutch release lever is brought under the control of the turret interlock to enable the clutch to be disengaged if necessary at the 180 position in the event that the deck has to wait for pins. When the deck is full and the last or tenth pin is placed therein, the turret cam projection 52 contacts the long link follower and such moves the long link to rotate the rear interlock cross shaft 39 and re-engage the clutch 28.

The first switch 10 is mounted on a structurally stationary portion of the pinsetter structure and is actuated by an auxiliary lever 60 attached by a clamp 62 to the rear interlock cross shaft 39. FIGS. 3 and 4 show in detail mounting of the first switch 10. A structural brace member 64 extends transversely through the pinsetter machine, and such is used for a support of a turret jam microswitch 66 and for mounting the first switch 10. The structural brace member 64 has a bracket 68 extending upward therefrom on which the turret jam microswitch 66 and the first switch 10 are attached in a side by side relation. The turret frame 70 has a rear portion with a protrusion 72 extending rearwardly therefrom. The turret jam microswitch 68 contacts the protrusion 72 on the rear of the turret frame 70. The turret jam microswitch functions in the circuit of the pinsetter to stop its operation thereof in the event a pin or a foreign object becomes lodged between the deck and the turret. The rear interlock cross shaft 39 extends through the turret frame rear portion as shown with the switch actuator lever 60 attached to the end portion of the shaft that extends beyond the frame 70. Normally, the rear interlock cross shaft 39 extends beyond the frame 70 and it is fitted with a lock to hold the shaft in a fixed longitudinal position relative to the frame; this lock is removed and replaced by the lever 60. The lever 60 has a clamp portion 62 for clamping it to the end portion of the rear interlock cross shaft 39. The clamp portion 62 of the lever enables the lever to be properly adjusted in position on the rear interlock cross shaft 39 to contact switch 10. The rear interlock cross shaft 39 rotates between two positions; a first position when the deck is raised and a second position when the deck is lowered. With the rear interlock cross shaft 39 in the first position (deck raised), lever 60 contacts switch 10 and holds the contacts of the switch open. With the rear interlock cross shaft 39 in the second position (deck lowered), lever 60 does not contact the switch 10 and the contacts of the switch are closed.

FIG. 6 shows a schematic diagram of the electrical circuit of this embodiment, (I), of the controller of this invention. The electrical circuit includes an input connector 74, an output connector 76, a transformer 78 and a solenoid operated relay 80, having two sets of contacts, the

switches

10 and 12 and a bypass switch 82. The input connector is preferably a plug-like connector and is connectable in the circuit which normally provides power for the electric motor 18. Electrical power supplied to the motor 18 is 220 volts single phase alternating current. The transformer 78 is connected to the

wires

84 and 86 from the input connector 74 and it has-an output of 24 volts alternating current which is used'to operate the switches and the solenoid of the relay 80. A'ground wire 87 is provided between the

connectors

74 and 76 for safety. The relay is provided with two sets of

contacts

88 and 90 which are normally open and -are closed when the solenoid is energized.

Switches

10 and 12 are preferably microswitch type switch structures enclosed in

housings

92 and 94, respectively. The bypass switch 82 is closable to complete the circuit and operate the motor 18. The bypass switch 82 is provided to operate the machine for servicing purposes and it is not required for normal operation of the machine. In normal operation switch 82 is open as shown in FIG. 6 and has no effect on the machine.

Switches

10 and 12 are normally open switches, open when the machine is idle and closed in operating sequence when the machine is in use. FIG. 6 shows switches 10, 12 and 82 in their normal open positions.

FIG. 5 shows the structure of the control box 16 which mounts the transformer 78, relay 80, input connector 74, output connector 76, and bypass switch 82. The control box 16 includes a housing which is mountable on an electrical conduit 102 existent on the pinsetter machines. The control box 16 has the male type input connector 74 rigidly mounted in the housing 100'so it can be engaged in an existing socket in the conduit 102. The output connector 76 is preferably a female socket rigidly mounted in the housing and connectable with the power line to the motor 18 by the plug 98. The motor 18 has a power wire 96 with a male plug 98 on the end which is normally connected with a female socket mounted in the conduit 102 of the machine structure. Preferably, the housing structure 100 is attached to the conduit 102 by a holding strap 104 with a spacer member 106 placed between the conduit and the housing on the end opposite to the input connector 74 so the housing can be rigidly mounted on the conduit 102. In practice, the controller of this embodiment, (1 of this invention is provided with the relay 80 preferably rated at 20 amps and 24 volts continuous duty. Practice has shown that power required for the l horsepower electric motor 18 is approximately 30 to 35 amps at starting time and operation of the motor re quires 5 to 6 amps.

In the use and operation of the controller of this embodiment, (l), of this invention, the basic operation of the bowling pinsetter is no different than it is without the controller except that the motor 18 is stopped during the times when the pin distribution system of the pinsetter is idle or is not required for operation. Following is a description of operating characteristics of the pinsetter with and without the controller of this invention. The pinsetter controller of this embodiment, l is constructed and adapted for use on the identified pinsetters in the A-l model and the A-l model having the jet back modification. All pinsetters necessarily have three basic cycles which are dictated by the bowling game itself, such being the strike cycle, the first ball standing pin cycle, and the second ball standing pin cycle. In the strike cycle the bowler knocks all the pins from the end of the bowling lane; the pinsetter detects this and sets new pins on the end of the bowling lane. In the strike cycle for the model A-l pinsetter the pin distribution system is required to operate approximately 12 seconds, and in the A-l model with the jet back modification the pin distribution system is required to operate 10 seconds. During the strike cycle the motor is required to operate an additional time so that the pin distribution system can fill the deck with pins; this time is normally approximately seconds, making a total of approximately 27 seconds, however, these times can be longer if a pin is delayed in the pin gathering apparatus portion of the pinsetter. In the second ball standing pin cycle the bowler has thrown two balls and a pin or pins are still standing on the end of the bowling lane; the pinsetter detects this; it removes the standing pins and sets new pins for the next player. The operating time for the pin distribution system of both A-l model pinsetters in the second ball standing pin cycle is the same as the time for the strike cycle. In the first ball standing pin cycle the bowler has thrown one ball and pins remain standing on the end of the bowling lane; the pinsetter detects this and waits for the bowler to throw the second ball. The time required for the pin distribution system of the pinsetter to operate in the first ball standing pin cycle is 15 seconds for the A-] model pinsetter and 12%. seconds for the A-l model pinsetter with the jet back modification. In operation of the A-l model pinsetter the operating time is comprised of 12 seconds for operation plus an additional 3 seconds for overtravel making the total of 15 seconds. In the A-l model pinsetter with the jet back modification the operating time in the first ball standing pin cycle is comprised of 10 seconds for operation plus an additional 2 /2 seconds for overtravel making the total of 12/2 seconds. During operation of the pinsetter without the controller of this invention. the motor will operate the pin distribution system as long as the machine is turned on; therefore, it will operate the pin distribution system during the times mentioned in the various cycles after the pins have been set on the bowling lane or left standing on the bowling lane until the bowler delivers the next ball to again start sequencing of the machine. In practice it has been observed that approximately 30 seconds lapse during the time when the pin distribution system is no longer needed and the bowler delivers the next ball where players are taking turns in succession. Obviously, this time may vary up to a few minutes or longer where players are not taking turns in rapid succession. With the automatic pinsetter controller of this invention, the motor of the pinsetter will run normally approximately 30 seconds as that is generally approximately the time required considering sufficient time for the deck to be filled in the strike cycle or second ball standing pin cycle. Obviously, in view of the observation as to player return times, without the controller of this invention the pinsetter will operate approximately 60 seconds per frame per bowler whereas with the controller of this invention, it will operate approximately 30 seconds per frame per bowler or in other words approximately 50 percent of the time when the machine is turned on for operation. The time which the pinsetter controller turns off the motor is the idling time of the machine that is unnecessary operation. Stopping the motor during this idling time stops the motion of 1 l belts and numerous pulleys, bearings, etc., in the pinsetter machine which would otherwise be moving because of operation of the motor.

In the use and operation of the controller for automatic pinsetters of this invention, the operation of the controller of this embodiment, (l), is as follows during the several operating cycles of the pinsetter. Operation of the pinsetter controller in the strike cycle and the second ball standing pin cycle is the same regardless of the operating differences in the function of the pinsetter mechanism. When the ball is thrown and the ball impacts at a trigger mechanism of the pinsetter which rotates the starter bell crank 36 pulling the clutch latch 34 from the clutch actuator link 32 which lets the plunger lever 31 rotate counterclockwise to raise the arm 41 of the switch 12 thereby closing the contacts of the switch 12 and starting the motor 18 which operates the pin distribution system. Switch 10 closes as the rear interlock cross shaft 39 is rotated when the deck is full and descends to the floor for setting new pins. Switch 12 opens when the starter bell crank 36 is rotated clockwise replacing the clutch latch 34 in the clutch actuator link 32 when the clutch 28 is disengaged. Opening the contacts of the switch 12 at this time has no effect on operation of the motor 18 due to switch 10 being closed, thus completing the circuit as can be seen in examining FIG. 6. As the motor continues to operate the deck is raised; when it is in the proper position, the rear interlock cross shaft 39 rotates so that the lever 60 contacts switch 10 opening the contacts thereof. Opening the contacts of switch 10 at this time stops operation of the motor 18. When the motor stopped at this time, it will remain stopped until the next bowler throws his ball at the new set of pins just placed on the end of the bowling lane. Without the controller of this invention, the motor 18 would continue to operate and idle the complex mechanism of the pinsetter. In the first ball standing pin cycle the sequence of operation of the controller is slightly different from the strike cycle and the second ball standing pin cycle. When the ball is delivered and impacts at the pinsetter with the appropriate trigger mechanism, the starter bell crank 36 is rotated counterclockwise pulling the clutch latch 34 from the clutch actuator link 32, thus moving the arm 41 of switch 12 to close the contacts of the switch and start the motor. In this cycle the deck moves in at detecting motion to check for the presence of standing pins on the end of the bowling lane and the rear interlock cross shaft 39 is not rotated to close the contacts of switch 10, thus switch 10 has no effect on the operation of the pinsetter in this cycle. When the function of the cycle is completed and the starter bell crank 36 is rotated clockwise replacing the clutch latch 34 in the clutch actuator link 32, the arm 41 of switch 12 is moved to open the contacts of the switch thereby stopping the motor l8. In this first ball standing pin cycle the operation of the motor in the A-l model pinsetter is completed in 15 seconds, and in the A-l model pin setters with the jet back modification such is completed in 12 /2 seconds. At the end of the first ball standing pin cycle the bowler will deliver one additional ball in an attempt to knock the remaining pins from the end of the bowling lane. From the time when the motor 18 is stopped at this point by the controller until the time the bowler delivers the second ball the motor 18 will not operate so that the described portions of the mechanism will not idlev In practice it has been found through operation of the identified pinsetters for a considerable length of time with the controller that use of the controller, (I), of this embodiment of this invention to stop and start the motor 18 as described does not adversely affect the functioning of the pinsetter or the motor. Additionally,

it has been found that a considerable savings of electri cal power can be made by using the controller for automatic pinsetters of this invention as it operates the motor only approximately one-half the time which it would be operated without the controller of this invention.

An additional embodiment, (2), of the controller for automatic pinsetters of this invention is provided for using the controller with the A-2 model of the identified pinsetter. The controller effects the general operation of the A-2 model pinsetter the same as that for the first described embodiment, (1), of the controller of this invention in that it stops operation of the motor for the pin distribution system during idle periods. Normal operation of the A-2 model pinsetter is such that it requires approximately 8 seconds to operate in either the strike cycle or the first ball standing pin cycle. However, in the first ball standing pin cycle approximately 14 seconds is required for proper operation of the pinsetter to load the deck with pins in order to complete the cycle. In the second ball standing pin cycle or the strike cycle, the pinsetter may run from 14 to seconds depending upon the time it takes the pins to move through the distribution system to fill the deck.

The structure of the controller for automatic pinsetters of this embodiment, (2), of this invention, is substantially the same as the first described embodiment, (I), of the invention with the exception that a delay relay apparatus is included to insure operation of the motor for a predetermined certain period of time so the controller will allow enough time for proper operation of the A-Z model pinsetter. The controller of this embodiment, (2), uses the same pair of switches mounted with the clutch actuator mechanism in the pinsetter interlock system as described in detail above. For clarity in description the switches of this embodiment, (2), of the controller are referred to by the

same numerals

10, 12 and 82 for the switches mounted in the structure described above. The electrical circuit for the controller of this embodiment, (2), is shown in FIG. 7, the switches and their mountings are the same as shown in FIGS. 1-5. The pinsetter structure shown in FIGS. 1 and 2, particularly the clutch actuator mechanism, is the mechanism for the A-2 model of the pinsetter. The structure of the pinsetter mechanism shown in FIGS. 1 and 2 is essentially the same for all models of the pinsetter except that the A-2 model uses the cycle solenoid 35 to rotate the starter bell crank 36 whereas the other models use a mechanical linkage to accomplish the same result as noted, supra. Operation of the A-Z model pinsetter is substantially described above in conjunction with the description of the operation of the pinsetter and the description of the first embodiment, 1 of this invention. The operation of the pinsetter in the A-2 model pinsetter is no different with the exception that the cycle solenoid 35 rotates the starter bell crank 36 at the appropriate times in the operating cycle. Operation of the A-2 model pinsetter is more rapid than the A-l model pinsetter and the A-l model pinsetter with the jet back modification. This increase in speed is accomplished by changing the size of certain pulleys in the drive portion of the apparatus and refining other portions of the model A-l machines in order to increase the operating speed. The cycle solenoid 35 rotates the starter bell crank 36 for pulling the clutch latch 34 from the clutch actuator link 32 in a substan tially instantaneous motion. Increased speed of the pinsetter allows the mechanical apparatus of the pinsetter to accomplish the same functions in a shorter time than possible with the A-l model machines. Approximately 8 seconds is required for the mechanism of the A-2 model pinsetter to complete an operating cycle. Speeding up the operation of the mechanical portions of the apparatus does not necessarily speed the pin movement from the pin gathering apparatus into the deck as pin movement depends upon agitation of the pins in the pit and their movement into the pin elevator, conveyor, etc. In the strike cycle or the second ball standing pin cycle the pinsetter must run from 14 to 25 seconds depending upon the time it takes the pins to move through the pin gathering apparatus, the conveyors, etc., and fill the deck. Since switch 10 which controls turning off the motor when the machine is operating in the strike cycle or the second ball standing pin cycle the controller will function to turn off the motor when the deck is raised at the end of either of these cycles without regard to the 8 second operating time of the other portion of the machine. In the first ball standing pin cycle approximately 14 seconds is required for proper operation of the A-2 model pinsetter which is approximately 6 seconds longer than the approximate 8 seconds operating time of the gearbox portion of the machine. Inasmuch as the clutch actuation mechanism is used by the controller for stopping and starting the motor in the first ball standing pin cycle, the delay relay portion of the apparatus is required to prevent the motor from being turned off prematurely. The delay relay apparatus is provided in the controller of this embodiment, (2), to extend operation of the motor for approximately a 6 second period after the time when the clutch 28 is disengaged so the motor will operate for the normal-time (approximately 14 seconds) required for the first ball standing pin cycle.

FIG. 7 shows in detail the electrical circuit for the controller of this embodiment, (2). The electrical circuit for the controller of this embodiment, (2). generally similar to that described above and is provided with the operating switches 10 and 12 and the bypass switch 82 and it additionally includes the delay relay apparatus which is indicated generally at 110. The controller includes an input connector 112, a transformer 114, a solenoid operated relay 116 having a pair of contact sets 118 and 120, an output connector 122, the

switches

10, 12 and 82 and the delay relay portion of the apparatus 110. The delay relay apparatus 110 includes an electric motor 124 having a cam 126 mounted on its output shaft to operate a switch that is indicated generally at 128. Leads or

wires

132 and 134 from the input connector 112 are connected to the output connector 122 via the contact sets 118 and 120 of the solenoid operated relay 116. A ground wire 130 is provided connected between the input connector 112 and output connector 122 for safety. The transformer 114 is connected with the

leads

132 and 134 from the input connector 112. One wire 136 from the transformer 114 is connected to one side of

switches

10, 12 and 82 with the switches being connected in a parallel relation.

Switches

10 and 82 are connected by a wire 138 with the coil of the solenoid operated relay 116. Switch 12 is connected by a wire 142 to wire 138. Switch 128 has one contact 144 connected with switch 12 and the other contact 146 connected with a wire 148 joining it with the transformer output wire 136. The motor 124 has one power input wire 150 connected with the output side of switch 12 and the other power input wire 152 connected with the transformer output wire 140. Switch 128 has an extended actuator arm with a cam follower 154 mounted on the outer end portion thereof. The cam 126 has an offset portion 156 which is indented relative the perimeter portion of the cam for detection by the cam follower 154. Preferably, the cam 126 has a circular perimeter with the cam offset 156 being a substantially flat portion as shown in FIG. 7 so that the cam follower 154 will move the actuator arm of the switch 128 to open and close its contacts 144 and 146. Preferably, the motor 124 is an electrical motor connected with a gear drive to rotate the cam 126 through one complete rotation in approximately 14 seconds so that the contacts of the switch 128 can be closed for approximately 14 seconds then opened.

In operation of the controller of this embodiment, (2), the delay relay apparatus provides for a connection between the transformer 114 and the solenoid actuated-relay 116 which will be maintained for approximately 14 seconds from the time cyclic operation of the machine is begun. At the start of a cycle of the machine, switch 12 is moved to the closed position as the clutch plunger lever 31 is rotated counterclockwise. This sta'rts the motor 124 which rotates the cam 126 and closes the contacts of switch 128. As the motor 124 rotates the cam 126, switch 128 maintains electrical connection between the transformer output wire 136 and thesolenoid coil wire 138 through

wires

148 and 142. Approximately 8 seconds after switch 12 is moved to the closed position it is moved to the open position as the clutch 28 is disengaged and the clutch plunger lever 31 rotates clockwise as described above, however, electrical connection is maintained through switch 128 as described so that relay 116 remains in the closed position and the motor 18 continues to operate. Electrical power for the delay relay apparatus motor 124 is supplied to

wires

150 and 152 through switch 128 and wire 140. Fourteen seconds after the start of a cycle and approximately 6 seconds after the end of the cycle when switch 12 is moved to the open position the cams flat or offset portion 156 moves under the cam follower 154 and switch 128 is opened, thereby opening the electrical connection between the transformer 114 and the solenoid coil of the relay 116 which in turn stops operation of the motor 124 and at the same time opens the contact sets 118 and of the relay to stop the motor 18.

In regard to the structure of the controller for automatic pinsetters of this embodiment, (2), the

switches

10 and 12 are preferably microswitch type switches enclosed in housings as illustrated in the drawings with the delay relay apparatus 110, the solenoid actuated relay 116, the transformer 114, and the input and output connectors 112 and 122 mounted in a control box similar to that shown in FIG. 5. The motor 18 driving the pinsetter apparatus is a 220 volt alternating current electric motor of approximately one horsepower. The transformer 114 is preferably provided with windings to convert 220 volt power normally supplied to the motor to 24 volts alternating current for operation of the relay 116 and the motor 124 of the delay relay apparatus 110. The input connector 112 is preferably a male type connector rigidly mounted in the control box housing so that it can be engaged in an existing socket in the pinsetter structure which is provided for connecting the motor 18 in the pinsetters electrical circuit. The output connector 122 is preferably a female socket rigidly mounted in the control box housing so as to be connectable with the plug of the power line for the motor 18. Preferably, the relay 116 is rated at 20 amps and 24 volts continuous duty, which in practice has shown to be sufficient to operate the one horse power motor as it requires only 5 to 6 amps for operation.

In the use and operation of the controller for automatic pinsetters of this invention, the operation of the controller in this embodiment, (l), is as follows during the several operating cycles of the A-2 model pinsetter. Operation of the controller in the strike cycle and in the second ball standing pin cycle is the same regardless of the operating differences in the pinsetter mechanism. When the ball is thrown and impacts at the trigger mechanism of the pinsetter, the cycle solenoid 35 rotates the starter bell crank 36 pulling the clutch latch 34 from the clutch actuator link 32; this lets the plunger lever 31 rotate counterclockwise to raise arm 41 of the switch 12 thereby closing the contacts of switch 12 and starting the motor 18 which operates the pin distribution system and the motor 124 of the delay relay apparatus 110. Switch 10 closes as the rear interlock cross shaft 39 is rotated when the deck is full and descends to the floor for the setting of new pins. Switch 12 opens approximately 8 seconds after it is closed, specifically when the starter bell crank 36 is rotated clockwise replacing the clutch latch 34 in the clutch actuator link 32. Opening of switch 12 at this time has no affect on operation of the motor 18 since switch is is the contacts of switch 10 at this time stops operation of motor 18. In other words, approximately l4 seconds after switch 12 is closed switch 128 is opened which will stop operation of the motor 124 in the delay relay apparatus, however, this will have no affect on the operation of motor 18 since switch 10 is closed as it usually is when the deck is being filled with pins. Operating time of the pinsetter in the strike cycle or the second ball standing pin cycle may vary from l4 seconds to 25 seconds depending upon the time required to fill the deck and move it to the proper position so switch 10 will be opened. At the end of the strike cycle or second ball standing pin cycle, motor 18 is stopped and will remain stopped until the next bowler throws his ball at the new set of pinsjust placed on the end of the bowling lane.

The first ball standing pin cycle for the A-2 model pinsetter begins when the ball is delivered and impacts at the trigger mechanism with the cycle solenoid 35 being actuated to rotate the starter bell crank 36 in a counterclockwise manner pulling the clutch latch 34 from the clutch actuator link 32, thus moving arm 41 of switch 12 to close the contacts of the switch which in turn closes the contacts of relay 116 starting motor 18. In this cycle the deck moves in a descending motion to check for the presence of standing pins on the bowling lane and returns to the raised position, the rear interlock cross shaft 39 is not rotated to close the contacts of switch 10. Switch 10 remains open and has no affect on operation of the pinsetter in the first ball standing pin cycle. At the time switch 12 is closed the motor 124 in the delay relay apparatus 110 is started and switch 128 is closed. Approximately 8 seconds after the start of the cycle switch 12 is opened as the cycle solenoid 35 is released and the starter bell crank 36 rotates clockwise replacing the clutch latch 34 in the clutch actuator link 32 and arm 41 of switch 12 is depressed opening the contacts of the switch. Electrical connection in the controller is maintained to hold the solenoid 116 in the closed position by the delay relay apparatus 110 so that the motor 18 will continue to operate. Approximately 14 seconds after the start of the cycle or approximately 6 seconds after the opening of switch 12, the delay relay apparatus 110 causes the relay 116 to be opened thereby stopping the motor 18. As the end of 14 second time period approaches the cam 126 of the motor 124 is rotated so that the cam follower moves onto the cams flat portion 156 thereby opening the switch 128 at the end of the time period to disconnect the coil of the relay 116 so that the contact sets 118 and 120 of the relay 116 open thus stopping the motor 18. At the end of the first ball standing pin cycle the bowler will deliver one additional ball in an attempt to knock the remaining standing pins from the end of the bowling lane. From the time the motor 18 is stopped at the end of the first ball standing pin cycle (approximately l4 seconds from the start of the cycle),

the motor 18 will remain stopped until the bowler delivers his second ball. When the next ball is delivered, the machine will begin the second ball standing pin cycle.

In practice, it has been found that the operation of a pinsetter of the identified model of pinsetters having the controller of this embodiment, (2), to stop and start the motor 18 does not adversely affect the structure of the pinsetter or the motor. Additionally, it has been found that a considerable saving of electrical power can be made by using the controller of this embodiment of this invention with the A-2 model pinsetters because such controls the motor to operate approximately onehalf of the time it would normally operate without the controller of this invention. The time of operation for this pinsetter in the first ball standing pin cycle is approximately 14 seconds. It has been observed that approximately 30 seconds lapse during the time when the pin distribution system is no longer needed for operation and when the bowler or the next bowler delivers the next ball when players are taking turns in succession. Obviously, the time between ball deliveries may vary from a few seconds to a few minutes depending upon the manner of play of the bowler or bowlers. In view of these observations as to players times and machine operating times, it is obvious that the pinsetter would operate at least 55 to 60 seconds per frame per bowler whereas with the controller of this invention, it will operate from approximately 28 seconds per frame per bowler or in other words approximately 50 percent of the time when the pinsetter is turned on for operation. It is to be emphasized that the pinsetter controller of this embodiment, (2), turns off the motor when it is needlessly idling portions of the machine after a time sufficient for the machine to function or after the machine has completed necessary operations. Stopping of the motor during this idling time stops the motion of l l belts and numerous pulleys, bearings, etc., in the pinsetter machine which would otherwise be kept in motion because of the continued operation of the motor.

In the manufacture of the controller for automatic pinsetters of this invention, it is obvious that same can be easily constructed to achieve the end product. The controller structure including the electrical circuit thereof is generally uncomplicated and, therefore, easy to manufacture. Preferably, the controller is constructed with portions thereof mounted in a removably connectable control box so the controller can be added to existing machines as a modification. It is to be understood that the controller can be incorporated in the structure and electrical circuit of pinsetters in a permanent construction or in an original construction when the machine is built initially.

In the use and operation of the controller for automatic pinsetters of this invention, it is seen that same provides a substantial reduction of the operating time for the motor powering the pin distribution system of an automatic bowling pinsetter. The controller is specifically constructed and adapted for use on the aboveidentified models of the pinsetter and it is constructed such that it can be adapted for use on other pinsetters of the same general type or nature if desired. Practice has shown that the controllers of this invention substantially reduce wear on the pinsetter structure particularly in the pin distribution system thereof which considerably lengthens the life of the elements of the pinsetter thereby reducing necessity for periodic maintenance and part replacement which in turn reduces the operating cost of the machine. Practice has shown that operating the pin distribution system for a shorter period of time by using the controller of this invention it results in a considerable reduction in electrical power required to operate the pinsetter therefore a direct reduction in operating cost and a reduction in use of electrical power.

As will become apparent from the foregoing description of the applicants controller for automatic pinsetters, relatively inexpensive and simple means have been provided to reduce the normal operating time of the pin distribution system of an automatic bowling pinsetter machine. The controller structure is economical to manufacture, simple to install on the pinsetter structure and functions in conjunction with the control system for the pinsetter without modifying the operation of the pinsetter other than to start and stop operation of the motor powering the pin distribution system of the pinsetter during periods when it is not necessary for the motor to operate. The controller of this invention is usable to reduce the cost of operating a bowling pinsetter by reducing the power requirements therefor and reducing the wear on portions of the mechanical system.
