Application filed June 22,

To all wlwm it may concern;

Be it known that we, CLARENCE W. Home and EUGENE A. COPELAND, both ofWorcester, in the county of Worcester and State of Massachusetts, .both citizens of the United States, have invented a new and useful Imthe accompanying drawings, forming a part of this specification, in explaining its nature.-

.The present invention relates to an improvement in coin or check controlled vending machines and essentially to a poweroperated machine.

ther description of its construction and operation.- .In general the operation of the device is to measure coins for diametrical s ze, "and other details'referred to in said application. If the requirements of the device are not satisfied the coin will be ejected by the device and fall into a hopper 4. and thence to a chute 5 connected with a rejected coin pocket 6 arranged on the outside of the casing (not shown), which incloses the entire machine, and where it may be recovered, by theone inserting the coin. if the requirements of the testing device a are satisfied the coin will descend through it and pass into and through a downwardly inclined chute or lead 7.

The machine is started by the coin during its descent through the chute 7, this being. initially accomplished by the engagement oithe coin with a trip lever 8 which controls, and as a part of such control, e ects the release of a drop lever hammer 9 the fall of J 'Which starts the mach1ne, as will later he explained.

The trip lever 8 is arranged adjacent the lower end of the chute 7. The lever conrprises a butt or thickened portion 16 from the forward end or" which extends a wire 11 having a bent end 12. lhe butt of the lever is secured by a pivotal connection 18 to turn upon a supporting bracket 14 fixed to the frame of the machine. That portion of the i butt 10 which extends back or the pivotal connection presents an end surface or edge 15 and a top surface 16; it has also attached to it a downwardly and bacirwardlv incnned spur or finger 17. The bent end 12 of the lever is contained within a slot 18 cut within the side, and preferably both sidesoi the ver and slot in relation to the way through the chute or path traversed by the coin in passing through the chute is such that, wheno AnENcE w. HOBBS AND EUGENE A. coPELANn, oE-woncEsrEn, mssncnusnrrs,

. continues its course through the chute.

Arranged back of the trip lever 8 is an angular bent lever or dog 20 pivotally secured to the frame of the machine. This lever or dog has arms 21 and 22, respectively, of which the arm 21 is an overwei hted arm and has secured to the side thereof a pin 23. The arm 22 of the lever extends upwardly over the top rearend surface 16 of the trip lever and is provided with a yielding contact 24 which engages this surface as the dog is turned.

The drop lever hammer 9 is arranged adjacent and below the rear end of the trip l ver and is pivoted by a connection 26 to a bracket 27 fixed to the frame of the machine. This lever comprises simply a heavy bar controlled to assume a slightly inclined vertical inoperative position and g'ra'vitating therefrom when released to a substantially horizontal working position, the descent of the bar being arrested by a yielding stop 28 on the frame of the machine. The relative arrangement of the parts is such that when accupying its substantially vertical inoperative position the forward or free end of the hammer has bearing against the rear end 15 of the trip lever, this lever then occupying its operative position as outlined above.

The overweighted arm 21 of the dog will then be slightly displaced and have bearing against the end of the hammer. When the trip lever is rocked by the coin on its descent through the chute the rear end of the lever will become raised, releasing the hammer which then falls by gravity. Simultaneously with the fall. of the hammer the arm 21 of the dog will move forward seeking its center of gravity, and the pin 23 carried by it will be moved to occupy a position beneath the spur or finger 17 on the end of the trip lever and act to hold down the trip lever in that position to which it has .beenrocked by the coin with the bent end 12 of the lever. occupying a position at the bottom of the slot in the chute. These positions of the trip lever and its controlling dog are maintaineduntil the return of the hammer. As the hammer is raised the end thereof will pass beneath the under side of the rear end of the trip lever and'engage the arm 21 of the dog, moving'thisarm'baokward and the pin 23 carried by it from beneath the s ur 17 and at'the same time the 0g that the arm 22 thereof or. contact 24 chine.

carried by it will be brought into engagement with the top surface 16 at the rear end of the trip lever, rocking it and restoring it to its initial raised or operative position, all the parts then being in position to again operate as above described.

The energy developed by the fall of the hammer starts the machine. The motive power employed is an electric motor 35 through which a current is passed from any convenient source of supply byleading-im.

and-out wires 36 and 3:, respectively (see Fig. 3). The wire 36 is provided wlth a switch by which the circuit is made or broken, the switch comprising a contact member 38 which is moved into and out of engagement with separate contacts 39 and 40, respectively, in the leading-in wire. The contacts 39 and 40 are each carried by a supportingarm 41. Both arms are secured to an insulated block 42 which in turn is threaded pin 47 which extends through a.

hub 48 on the upper end of a lever 49. The pin and contact member carried by it are adj ustably secured by nuts 50 arranged upon the pin and bearing, respectively, against the ends of the hub. The lever 49 is p1votally secured by a pin 51 to a fixture 52 on the bed 45 of the machine. The lever has a .boss 53 projecting laterally from the side thereof and carries alsoa cam roll 54. Be

yond the point of its pivotal connection the lever is extended by anarm 55 against which bears-a spring-pressed piston or plunger 56. This piston'is contained within a casing or housing 57 arranged on the bed of the ma- The piston has extending from the rear side thereof a stem 58, whichextends through the-rear end of the housing and is held by a 'pin'59 which extendsthrough the end of the stem and bears against-the outer end of the housing. Arranged upon the stem within the housing is a spring 60 which bears-against the inner end of the'piston and i also against the inner-end of the housing. The; tensional bearing of the spring against the plunger forces it outward to have a con- 'stant tensional bearing-against the arm 55 of the cam-lever 49, which tends to throw the working arm of the lever forward and-the contact member 38 carried by the lever into a disengaging position thereby leaving the circuit controlhng the motor normally open.

62, 63am a brace of levers. These levers at the bottom ends thereof are secured to a common connecting hub 64 which is pivotally secured by'a pin'65 to brackets 66 on the bed 45 of the machine. At .the top ends the levers are connect'd by a common crosshead' 67. The lever 63 beyond the cross- 67 of the respective levers presents on the top side thereof a plane surface 72 and also an incision forming a shoulder 73. With this plane surface and shoulder of the cross.- head there cooperates a releasable latch 74, later to be referred to, which assists in controlling the brace of levers.

Arranged back of the cross-head 67 is a spring-pressed plunger 76 contained within a casing or housing 77 on the bed of the machine. This plunger is provided with a stem 78 which extends through the rear end of the casing 77, thence loosely through the .cross-head 67. The end of, this stem is the stem. Arranged upon the stem 78 with- .in the casing is a coiled spring 82. According to the-arrangement and operation of'the parts the plunger is drawn back into the casing contracting the spring 82, which accordingly bears with compression against the plunger to make the same active. The drawing back of the plunger for compressing the spring is obtained, as will later be more fully explained, by the moving outward of the cross-head 67, the cross-head then bearing against the nut 79 which through the stem 78 withdraws the piston or plunger to compress the spring.

caring against the outer end of the plunger, outside the casing in which it is contained, is a boss 83 on the side of a lever 84. This lever is pivotally secured to a fixture 85 on the bed of the machine, the pivotal connection being secured by the pin 51, which is the same pin that forms the. pivotal connection for the lever 49 above referred to. Beyond the point of its pivotal connection the lever 84' is extended by an arm 86 against which bears a spring-pressed piston or plunger 87. The tensional bearing of this piston operates to hold the lever 84 in a normal retracted position with bearing against the end of the plunger. The yield ing retention of the lever 84 is such, however, that it may be moved forward by the plunger as the plunger is moved forward by the action of the spring 82 backing it. The lever 84 is positioned'to engage the boss 53 on the lever 49 as the lever 84 is moved forward by the plunger 7 6. The top 88 of the lever 84 provides also a stop to which special reference will later be made.

From the above description it will be seen that both the cam lever 49 and the lever 84 are impelled to normally maintain a retracted position. Assuming that both of these levers are in their retracted positions with the plunger 76 also retracted and the spring 82 compressed, the following action will take place in the event that the plunger is suddenly released: The plunger will first engage the lever 84 and throw this lever forward. As the lever 84 is thrown forward by the plunger it will carry the lever 49 with it through the engagement of the lateral offset 88 onthe lever 84 with the boss 53 on the lever 49. The throwing forward of thelever 49 throws the contact member 38 carried by this lever into engagement with the contacts 39 and 40 of the leading-in wire and accordingly closes the circuit. The'proper positioning of thecontact member between the contacts 39 and 40 is defined by the engagement ofthe lever 49 with aielding stop arm 90 suitably fixed to the be or frame of the machine. As the plunger is moved back or retracted compressing the spring 82 the lever 84 will follow it back maintaining its contact therewith.- The lever 49 would also be retracted, breaking the circuit, unless this lever was otherwise prevented from retraction, as is the case,-as will later be explained, it being especially to be noted that both the plunger 76v and the lever 84 may be retracted without retraction of the lever 49 owing to the separation and independent action of the levers 49 and 84.

The plun ger 76 is retracted and. set, compressing the spring 82 and permitting the normal retraction of the levers 84 and 49 by the moving outward or pivotal retraction of the levers 62 and 63 and cross-head 67 carlever rgivotally secured to the bed of the machine ehind the cross-head by a pin 92, and comprises arms 93 and 94 and also a pro ectingwing or finger 95. The arm 93 is a latchforming member or. that which makes a latching engagement with the cross-head 67, this arm being yieldingly maintained to bear against the top side of the cross-head by means ofa spring-pressed-finger 96 bearing against the arm 94 of the device. As the cross-head is moved back into its retracted position'the latch member or arm 93 will slip over the top surface of the cross-head and into the incision formed therein and bear against the shoulder 73', maintaining the cross-head accordingly in itsretracted position against the tension of the spring82 when the I ressure tending to retract the I,

cross-head as been relieved. Y I

WVhen the latch is released from the crosshead the plunger will then be thrown forward by the spring 82, closing the circuit for energizing the motor and starting them'achine as above described. The release of the latch from the cross-head is effected upon the drop of the hammer 9 by a lever 97 fixed to a spindle 98 which turns in a bearing 99 on the bed of the machine. One arm of the lever 97 bears a wheel 100 adapted to engage the finger 95 of the latching device, turning the same and raising the latch arm 93 for releasing the cross-head as the lever 97 is turned. The lever 97 is turned by the hammer 9 on the drop thereof by means of a connecting link 101 pivotally secured at one end to the lever 97 and at the other end to the drop hammer. Attention is also directed to the arm 102 secured to the spindle 98 and cam wheel 103 carried by the arm.

After the closing of the circuit the motor operates to turn a main shaft 105 which turns within boxes 106, 107, respectively, mounted on the bed of the machine. Motion is applied to the shaft 105 from the motor through a motor shaft 108, worm 109, worm gear, 110, friction members 111 and friction plates 112 and 113, respectively. The worm 109 is driven directly by the motor shaft. The worm gear 110, immediately driven by the worm, is loose upon the main shaft 105. The friction washers 111 are disposed between the friction plates 112 and 113 and the sides of the worm gear. Both friction plates 112, 113, are keyed to the main shaft to rotate therewith, but are movable longitudinally thereon. The hub of the friction plate 112 has bearing against the side of the fixed box 106 supporting the main shaft. Arranged upon the main shaft and bearing against the outer end of the friction plate 113 is. a coiled spring 114 held under tension by means of a nut 115 on the end of the shaft. The arrangement of the parts is such that the main rotate independentl shaft will be driven from the motor only through frictional contact between the fric- -tion plates, interposed washers and sides of become suddenly stopped, or to compensate for any momentum of the motor after the stopping of the main shaft during the ordina il'y operation of the machine.

he main shaft v105 carries a series of cams 118, 119, 120 and 121, respectively, all of which are suitably fixed to the shaft and rotated thereby. Of these cams the 'cam 118 is a timing with the top 88 of the lever 84, acting as a stop, permits only a single com lete revolution of the main shaft during tne operation of the machine after the insertion of the COlIl.

The cam 119 is a reset cam, operating, as will presently be more fully explained, soon after the startingof the main shaft to en- .cam which by its engagement,

gage the cam wheel and throw back the cross-head 67 until it is automatically engaged and held in an operative position by through the link 101 raises the drop ham-,

mer 9, resetting it, and also the trip lever 8.

Cam 120 is a contactcontrolling cam operating by engagement with cam roll 54 on lever 49 to hold the contact member 38 in place between the contacts of the leading-in wire and thereby to maintain the circuit closed during and after the resetting of the trip mechanism and parts acting with it, the lever 84, which initially assisted in closing the circuit, being then allowed to return to its original position, when its top 88 may be engaged by the timing cam 118 at the end of the shafts cycle of rotation.

The cam 120 acts also to release the lever 49 to assume its normal position, separating the contacts and breaking the circuit at the end of the cycle of movement of the main shaft.

The cam 121 is one controlling a coin detector $125. As has been previously described, the coin after rocking the trip lever 8 for releasing the hammer and starting the machine, continues its course through the chute 7. From the chute it enters the coin detector, which is a detector for detecting standard coins of proper denomination like that shown 'and described in Letters Patent of the United States No. 1,042,968, of October 29, 1912, and to which reference is hereby made for a further descri tion of its construction and operation. 'e only elements necessary to be referred to in the present connection are the o erating handle 126 or the detector and a so the movable valve 127, which handle and valve correspond, respectively, with the operating handle and valve shown in said p2 tent. Connecting-with the operating handle 126 is a link 128 which has pivotal connection' with the cam'lever 129 pivotally secured to the bed of the machine at point 130 and bearing a cam roll 131 adapted to be engaged by the earn 121, before referred to. ngaging the lever 129 is a spring-pressed piston 132.

After entering the detector 125 the coin will-come to rest substantially as referred to in said patent. Thereupon by the turning of the main shaft the cam 121 will engage the cam roll on the lever 129, rockmg this lever and, through the link 128,

' will draw down the operating handle of the detector to test the coin resting in the detector. If the coin is rejected the inherent operation of the detector is such that the detector valve will not move and the coin will drop therefrom into a rejection chute 134 through which it passes to the rejectedcoin pocket 6 where it can be recovered. On the other hand, if the coin is accepted, then the detector will operate through its own potential energy to swingthe valve 127 into a position to drop the coin into a directing Ghute 136. It will further be explained that the action "of thecam 121 occurs approximately during the first half revolution of the'main shaft and some timeduring the remaining half revolution of the shaft the cam will have completed its operation, when the operating handle of the de- -tector will be returned to itsfinitial posimounted to turn on the main shaft. The

tion by the return of the lever'129 and link 128 which connects withthe handle, these parts being returned by the spring-pressed .piston- 132.

The main shaft 105 during substantially the latter half ofits cycle. of rotation drives,

sleeve carries a driving sprocket 141 the motion of 'which is communicated to a sprocket 142 on shaft'143 through a sprocket 1 chain 144 and thence to the delivery mechanism proper as such may be. The sleeve 140 bears also a clutch member 146 which is arranged beneath the end of the chute 136, and it consists of a flanged-hub of which 147 represents the hub and 148, 149 the respective spaced flanges thereof. These flanges have grooves 150 formed on the inner sides by which a coin dropped from.

the chute may, when the hub is in a prop-' erly turned position, enter-the grooves and be maintained in an upright position .between the flanges of the hub, the coin then resting upon the hub. 'The .grooves 150 are formed in the flanges on diametrically opposite sides of the clutch member so that a coin dropped from the chute may enter the clutch member at every complete half revolution thereof.

The clutch member carried by the main shaft, and by which the delivery-actuating mechanism is coupled to the main shaft, consists of'a bent arm'orfinger 152 carried by a collar153 fixed to the shaft. The arm or finger 152 extends up and around one of the flanges of-the clutch member 146, the adaptationv of the clutch member, in other words, being such that as 'the main shaft is turned the clutch arm or finger carried by it will engage. a coin borne by the clutch member of the delivery-actuating meeha nisin and thereby operate this mechanism.

The delivery-actuating: mechanism is oper ated during approximately :the ;last half revolution of the main shaft and. accord ingly operates through an arc of 180. Just before themai-n shaft has reached the end of its movement the speed of the deliveryactuating mechanism is increased so that this mechanism will travel slightly ahead of the driving shaft and then be stopped in a precisely defined position. This effect is obtained by means of a cam 155 having abruptly and inwardly-inclined edges '156. Bearing against this cam is a cam roll 157 carried bya lever 158 pivoted to a bracket159 fixed to the bed 45 of the mative adaptation of the parts is such that the roll will engage either one or the other of the inclined edges 156 of the cam just before the end of the cycle of movement of the driving shaft, thereby causing the cam anddelivery-actuating mechanism to travel ahead of the driving shaft and then be stopped by the cam roll seatingv itself at the lowest point of the depression in the cam. The immediate effect of this auxiliary device for propelling the deliveryactuating mechanism to travel ahead of the main shaft and then bring it to a stop is to release the coin from the pressure exerted by the clutch finger 152, the coin then being free to drop by gravity into any suitable coin receptacle (not shown) for receiving it. The device also acts to stop the delivery-actuating mechanism in just "the precise position for the clutch hub of this mechanism to receive another coin at the time of the next operation of the machine.

From what has been described it will be seen that it is quite necessary during the cycle of operation of the machine that no coin should be admitted to the operating parts of the machine until it has completed its cycle of operation. Accordingly for such purpose of exclusion the following means is provided: Pivotally secured to a bracket 165 on the side of the coin chute 7 is a lever v166 one arm of which carries a valve 167 which, as the lever is turned, enters through a slot 168-formed in the side of the chute and closes the passage way through the.

chute, thereby preventing the passage of a coin therethrough. Foriturning this lever immediately after the passage of a cointhrough the chute, the other arm of the lever is provided with a bent forked end 169 of thelevcr, thereby turning the same and,

- closing the passage through the chute. The

reverse turning of the lever and opening of the passage is effected by movement of the trip wire in a reverse direction during the resetting of the trip mechanism and is effected by the wire drawing against the prong 171 of the lever and thereby moving the valve 167 to an open position and maintaining it in such position, thus clearing the passa e through the chute.

he general operation of the machine is as follows: Assuming a coin to be inserted through the coin gage 2 and to have passed by the coin-testing device 3, the coin will then enter the passage through the chute 7. During its passage through the chute 7 the coin will engage the trip lever 8 turning this lever and releasing the droplever 9. As the trip lever is turned the lever 166 will be turned by it and the valve 167 carried by this lever will close the passageway through the chute to the entrance of another coin. Both the trip lever 8 and the chute-controlling lever 166 will be, maintained in their turned positions and the chute closed during the ensuing operation of. the machine and until the return of the trip mechanism, which operation is completed, as will later be explained, during the latter part of the machlnes cycle of operation.

The fall of the drop hammer 9 starts the machine by releasin latch v74 through action of link 101 and iaver 97, the roll 100 on which engages finger 95 to displace the latch and thereby release it from cross-head 67. The plunger 76 is then let go and, actuated by spring 82, it displaces lever 84 which in turn displaces lever 49 carrying contact member 38 betweencontacts of, the leadingin circuit, thereby closing this circuit and I starting the motor, which through the connecting mechanism'turns the main shaft 105.

The main shaft is turned by the motor through only one complete revolution, and carries with it the various cams 118, 119, 120 and 121. The initial. turning of the shaft turns the timing cam 118 by the end of the. stop lever 84, which 'at this time 1s.

displaced by the previous operation. As the turning of the shaft continues the reset'cam 119 will first en age the cam 70 carried by the cross-head 6' and force backthe cros'shead againstthe tension of spring 82 contractin this spring. The cross head is forced Tack until the latch 74 drawing over the head of the cross-head, will engage the shoulder 7 3 therein and hold the, cross-head in its retracted and operative position, when the bearing ofthe reset cam is relieved. The

that at the end of the complete revolution I of the shaft the time cam may engage the top 88 of the lever 84, which accordingly stops the rotation of the main shaft in precisely its initial position. Any jar upon the motor by the sudden stopping of the main shaft is relieved by the slippage of the driving connections'between the motor and the shaft as before explained.

During and after the return of lever 84, contact member 38 is held in place between the contacts of the leading-in wire for holding the circuit closed by the engagement of contact-controlling cam 120 with cam roll 54 on lever 49, the bearing of this cam continuing until the end of the main shafts cycle of movement when the cam allows the lever 49 to return, causing a quick break of the switch connection, thereby stopping the motor.

After the resetting of cross-head 67, the continued movement of the main shaft brings the reset cam 119 to contact with cam roll 103 which through arm 102 and connecting spindle, returns lever 97 and thereby through connecting link 101, restores the trip mechanism to its initial position and opens the passage through the chute 7 to the entrance of another coin, this action being completed during the latter half of the main shafts revolution.

Durin approximately the first half of the revo ution of the main shaft, the coin detector cam 121 will have operated upon lever 129 which through connecting link 129 turns the operating handle of the detector to test the coin resting in the detector the coin already having entered the detector from the chute 7. If the 'coin is found unsatisfactory it is'delivered through valve 127 of the detector to the rejected coin chute 134, the machine then simply completing its cycle of operation without connecting the driving mechanism with the 1 delivery-actuating mechanism, which under such clrcumstance remains pas- (all sive, andv no goods are delivered. On the other hand, if the coin isfound satisfactory, the operation of the detector is to turn by its own potential ener its valve 127 and .thereby controlor :dlrect the coin tochute 136, which-,directs the com to the,

clutch mechanism between the driving shaft and the delivery-actuating mechanism. the

the detector cam to test and release a coin during approximately the first half of the revolution of the main shaft, the coin accordingly will be released to form a connecting link between the main shaft and the delivery-actuating mechanism throughout the last half of the shafts revolution. At

- some time, also, during the latter half of the main shafts revolution the detector cam 10 will operate to ermit of the restoration of the detector mechanism to its initial position, which effect is obtained by the tensional bearing of the plunger'132 against the lever 129 which connects with the operating arm of the detector.

As the driving shaft approaches the end of its revolution the delivery-actuating mechanism will be advanced by thebearing of the cam roll on the spring-pressed lever 158 against the cam 155, and which not only moves the delivery-actuating mechanism to release the coin from the clutch members, but also acts to stop the delivery-actuating mechanism in precise position for the next operation of the machine.

The action ofthe machine is very rapid, all the operations being completed after the insertion of the coin in about two seconds.
