SAMUEL G. CRANE, OF TOLEDO, OHIO. 'ASSIGNOR' TO TOLEDO SOALE COMPANY, OF

' TOLEDO, OHIO. A CORPORATION OF NEW JERSEY.

- ELECTRIC-CHECK-PRIN TIN G SCALE.

Application .filed November 7'0 all whom it ma concern;

Beit known that I, SAMUTEI'. G. CRANE, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, haveinvented certainnew and useful Improvements in EIectric-Check-PrintingScales, of which the following is a' specification.

This invention relates to weighing scales, to automatic check printing scales. While inventions of scales of this type have heretofore been made, it is believed that no practical scale has hereto fore been devised which will automatically issue a printed check of the unknown weight of the commodity being .wveiglned without the aid of a manual operation.

The principal object of this invention is to' provide a scale which will automatically determine the weight, print the same upon a check, and issue the check by means entirely within the scale itself, the only operation efi'ected by the operator being the placing of the commodity 'upon the platform. Thus in stores and shops where commodities of unknown "weight are continually being placed upon the scale platter my improved scale is particnlarly'adapted, and also in factories where parts of machinery and the like must be accurately measured by the wei ht thereof, as when erated in 0011- I nection with a conveyor of any familiar type, and the successive commodities may be weighed and printed records of the weight issued in rapid succession without the as sistance or attendance of a weight checking clerk. It will be obvious that the scale is also adapted for many and various types of weighings. V

Another object of my invention is to provide a novel mechanism for so timing the operation of the printing mechanism that said mechanism willnot be actuated until after the weighing operation iscompleted and the weighing parts of the scale are at rest.

With the above and other objects in view which will readily appear as the invention is better understood, my invention consists in the novel construction, combination and a rrangcment of parts to be hereinafter more fullv described and particularly pointed out in the appended claims.

Reference is to be had to the accompany-- 21 1919. Serial No. s39.as.

\Vhile my invention is adaptable to many different styles and makes of scales, whether the load-offsetting device therein be spring, lever or pendulum, the present embodiment is adapted forv use in connection with dial scales where an indicating hand is adapted to swing over a' graduated chart to 'indi-.

cate the weight weighed. In the of 1 the commodity being drawings, "l designates the usual scale housing mountediipon flCOltlIflD 2 which connects with the base'and platform levers (not shown). 'As the (weighing or loadoffsetting mechanism of the scale forms no part of the present invention, I will de scribe it briefly, the mechanism being preferably of the type adapted to weigh comparatively heavy loads. The pendulum connform the pendulums will be swung upward-f;

ly into a position coun'terbalancing the weight of the load on the plat fornntbe penclnlums falling again to their normal or zero position when the load is removed from the scale platform. Asherein shown, the pendulum counterbalance mechanism comprises a pair of oppositely-disposed pendulums 5, each of which comprises supporting seg-' ments 6 secured on transverse. shafts, and the I two shafts are connected by crossbars 7 the,

segments 6 being suspended from the lower izcr bar ll.

ends of flexible supporting ribbons secured at their upper ends upon the framework of the scale. Intermediate the supporting segments of each pendulum isa somewhat larger segment 8, which is also fixed to the transverse shaft, said segment extend ing at its periphery between the pillars of the framework supporting the segments (5, and being connected to the upper'cnd, as at 9. to a flexible metallic ribbon 10 which extends over the arcuate face of the segment and is attached at its lower end to an cqnal- The construction of the two pcndnlums is substantially identical. and the ribbons 10 are connected to opposite sides of the equalizer bar 11. which is centrally connected, as by the link 12, with the upper end of the steelyard rod 4, which. as before described, is connected with the lever 3.

In the operation of the scale, when a load is placed on the scale platform. a downward pull is exerted on the equalizer bar ll, which is transmitted through the ribbons 10 to the larger segments 8. causing a swinging of'the pendulums 5 so that the pendulum weights are raised to a c'ounter balanced position. During the winging movementv of the pendulums to afset the weight of the load, the crossbars 7 a ,e moved vertically upward,- and through the medium of this vertical movement of the crossom's the weight indication on the dial is effected;- the erossbars 7 carrying a vertically disposed rack upon the indicator shaft 15 carrying the index hand 16. The indicator shaft 15 is mounted concentrically of the dial 17 having the desired weight raduations suitably inscribed thereon, as, or example. in the manner illustrated in Fi 1, with which graduations the index han 16 co-operates in indicating the weight of the load being weighed. "1 his pendulum counterbalance mechanism is sufficient to independently offset the weight of all loads within the capacity shown on the dial.

Supported within the column 2 and 00- operating with the scale beam pivoted therein is a timing switch mechanism, which, as will be apparent from the following descrip tion, comprises one of the important features of this invention. A resilient member 19 is .securely fastened to one side of the-column land extends across the upper portion thereof. it being suitably shaped so as to provide an elongated opening surrounding portions of the scale mechanism extending through the column, such as the sleelyard rod con necting the platform levers with the beam '3, etc. Mounted upon the free end of the resilient member 19 is a dash pot 20, the lower portion of which extends through an opening in the bracket 18, thereby permit- 13 meshing with a pinion 14 fixed Gil ting the dash pot to swing with this resilient member. Limiting means are preferably provided to prevent undue swinging movement of the dash pot and resilient member, as herein shown comprising adjusting screws 21 mounted in the member 19 adjacent the dash pot and adapted to contact the bracket- 18 when the limit. of the downward movement of the dash pot has been reached. A plurality of L-shaped guides 22 are adjustably mounted upon the column 2, the short arms of which are adapted to extend over 1 the edge of the member 19 and limit the upward movement thereof. Secured within the column 2 and above the resilient member are brackets 23 in which is journalled a transverse rock-shaft 24 having needle point or other suitable anti-friction bearings and carrying a crank arm 25'whiclris pivotally connected to the resilient member 19 by the link 26, and a crank arm 27 of much greater length than the arm 25 and extending in the opposite direction, the outer extremity of which operates between the shorter arms of upper and lower contact levers 28 and 29 respectively fnlcrumed between the vertical arms of a standard 30. The extremities of the longer arms of the contactlevers 28 and 29 are adapted to engage the upper and lower contact screws 31- and 32carried by but insulated frornthe bracket 18. The upper. lever. 28 has its -shforter arm operatively connected with a timing device 33, the purpose of which will appear inthe following paragraph. The plungerof the dash pct is operatively connected withthe scale beam 3 by means of the plunger rod 20 and serves to damp the vibratory movementsotthe delicate parts of the scale.

Thus, it will'be apparent that whilethe weighing mechanism of the scale is in opera tion the. scale beam 3 will be caused 'to vibrate, which will force the plunger to reciprocate within the oil cylinder of the dash pot. As the dash pot is suspended upon the free end of the resilient member 19, the action of the plunger in the oil will impart a vibrating movement to the dash pot switch 44 controlling the rotation of the which will causethe shaft 24 to be rocked by reason of the crank arm 25 and l nk 26.

The rocking of the shaftl124 causes the free end of the crank arm 27 to alternately en gage the shorter arms of the contact levels 28 and 29, and break the engagement of their longer arms with the contact screws 31 and 32. Thus, when the scale beam 3 is pulled downwardly, the dash pot 20 is moved correspondingly, causing the free end ofthe arm 27 to move upwardly and breaking the contact of the upper contact-"lever 28 with the contact screw 31. The shorter arm ofthis lever, 28 is connected to the timing device 33 and retards the movement of the lever 28 in resuming its normal position in engagement with the contact screw 31 to permit the current of electricity to flow through the switch set up by the levers 28- and 29 and the contacts 31 tively.

It ,is obvious that should the previously described switch mechanism alone be used, the circuit would be closed when the scale is at rest .and no load upon-the platform which would cause the printing mechanism to be actuated. In order to overcome this difii culty I provide in addition to this timing switch mechanism a master switchmechanism which is adapted to be closed only when a commodity is placed upon the platform of the scale. the arrangement being such that before the electrical current can operate the check-printing mechanism, both switches tnust be closed. This master switch is normally open and adapted to be closed upon the ownward movement of the steelyard rod 4. This master switch comprises a switch arm 35 mounted upon but insulated fromthe frame of the scale and is normally held in a raised position by means of a lug 36 of insulating material carried by the steelyard rod. A contact screw 37 is positioned to engage the switch arm 35 when the and 32 respecactuated until the completion of the weighing operation and which includes means for. rotating the driving mechanism for the printing disks proportionately to the rotation of'the index hand 16 when indicating the weight of the commodity on the platform of the scale and means for stopping the rotation of said mechanism when the correct arrangement of type numerals is obtained. More specifically, this mechanism comprises a disk 40 fixedly mounted upon the indicat-or shaft 15 and having a rearwardly projecting stop arm ilsecnred thereto in any suitable manner. This rearwardly-project- -in'g arm 40 co-operates with a rotating large driving gear 42, which is mounted with its axis in alignment with the shaft 15 and provided with as many teeth as there are pounds indicated upon the dial 1?. This rotating switch is normally closed and is broken when the gear 42 moves through a partial rotation corresponding to the movement of the index hand showing the weight of a connnodity on .the scale platform. This switch 44 comprises an insulating segment block 44' mounted upon a hub 45 of the driving car 42 and secured to the gear in any suita le manner. I A pair of spaced contacts 44 and 44" are secured to the peripheral face of the block 4%, while a flexible switch member4-i is secured to the contact 44 and engages the contact 44", thereby normally keeping the switch closed. The free end of the switch member 14 extends a certain distance above the contact 4-4 in the path of travel of the arm 41. Mounted upon the hub 45 in the rear of the gear 42 are a pair of spaced contact rings 46 and 47 electrically connected with the contacts 44 and 44" respectively through wires 46 and 47 (see' Figs. 5 and 9). Brushes 4S and 49 contact the rings 46 and 47 respectively. Mounted rearwardly of the rings 46 and 47 'is a standard in which is journalled in snit able bearings a shaft 50 keyed to the hub 45 and having secured thereon a pair of timing cams 51 and 52, the'purposeof which will appear later. Engaging the cam 51 is one end of a switch arm 53, the other end being pivoted to a standard 54, said arm normally being in contact with a contact screw 55 electrically connected with the switch contact screw 37 of the master switch Electrically connected with the standard 54 is a pole-c anging motor 56 which is provided with a inion secured to the armature thereof for driving the gear 42. A switch member 63 (see Fig. 8)- similar in construction the lower end of a right-angled arm thereof to be out of engagement with a contact screw 64. Upon rotation of the gear 42the cam 52 will be revolved, thereby lowering the arm 63 and permitting the engagement of the right-angled arm with the contact screw 64, thereby permitting the current of electricity to flow to a magnet 65supported by'the scale framework and in such position that when energized the ma net will attract the disk 40, thereby locking theindex hand and driving mechanism against rotation. (See Fig. 7.)

The, printing disk mechanism may be of any familiar type, the embodiment herein shown being one form particularly adaptable for use in connection with the present form of device. WVith particular reference to Figs. 3, 18 and 19, I have shown the printing mechanism as consisting of a plu rality ofdisks 57 having numerals arranged consecutively on the peripheries thereof and so arranged that upon rotation of the shaft 58 upon which the disks 57' are mounted, the numerals will be proport-ionatel moved to indicate successive pounds and ractions thereof. In order to provide means 1 for such rotation of the disks 57 I have shown a pinion 59 secured upon the end of the shaft 58 and in mesh with the driving gear 42', which, as hereinbefore stated, is provided with teeth in number corresponding to the capacity of the'seale in pounds- Upon the opposite extremity of the shaft'58 I provide a star wheel 60, which, when engaged by th'elatch 61, serves as a stop for the printing mechanism and serves to align the type numerals for clear printing. The arm of the latch 61 has one of its ends pivotally connected to the base of an electro-magnet 62, while the armature thereof is in such relation to said arm that when the magnet is energized the arm will be lifted, thereby permitting the free end to be retracted from engagement with the star wheel. (See Figure 13.)

When a commodity is placed upon the platform of the scale the weighing mechanism is actuated as hereinbefore described to offset the weight of the load. As the shaft 15 is rotated, carrying with it the index hand 16 to indicate the weight of the load, the disk 40 is'simultaneously rotated to position the stop arm 41. During this weighing operation the master switch 35 is closed but the timing mechanism, including the upper and lower switch levers 28 and 29, which is in circuitv with the switch 35 and checkprinting linechanism, is open, thereby preventing the actuation of the driving gear 42 and associated mechanism until the weighing operation is completed and the index to. a. standstill, thereby permitting the tim-*- ing switch to close. The current then flows from the service lug S located in the upper part of the scale housing and connected to a battery B or other 'source of electrical supply to the master switch 35 (which was closed as' the steelyard rod 4 was pulled downward to actuate the pendulums), thence to the switch 53 electrically connected with the driving motor 56 and to the magnet 62, which lifts the latch 61 from engagement with the star wheel 60, releasing the 'gear wheel 42 and associated mechanism. The motor 56 drives the large gear wheel 42 and causes the shaft 50 to revolve, and the cam disks 51 and 52 which are secured on the shaft'to operate the switch arms 53 and 63 respectively. The cam 52 is so timed that upon the beginning of the rotation of the gear 42 the switch arm 63" will he lifted, thereby closing the circuit in the switch which permits the magnet 65 to hecome energized, thereby locking the disk 40 and the weighing mechanism of the scale against movement. It will be remembered that the disk 40 carrying with it the stop. arm 41 has been rotated correspondingly to the index hand so that the stop arm remains in transverse alignment with theindex hand when indicating the weight of a commodity. When the disk 40 is locked by means of the magnet 65, the lug 41 provides a stationary rearwardly-extending stop adapted to engage the upper end of the flexible switch member 44 as the switch 44 revolves with gear 42, thereby opening the switch to stop the motor 56 and 'de-energizing the magnet 62, causing the latch 61 to re-eugage the star wheel 60 to prevent movement thereof. As the latch 61 drops back into engagement with the star wheel 60 under tension of a 5 ring 66, a circuit switch 67 is closed, there y energizing a magnet 68, to the armature of which is connected an arm 69 having formed at the end thereofa hammer adapted to impinge a paper strip or card upon the type disks when the magnet is energized. Carried by the arm 69 is a finger 70 adapted to close a circuit switch 71 as the arm is attracted to the magnet 68, thereby causing a magnet 72 to become energized, the armature 73 of which is arranged to actuate a pole-changing device electrically connected to the motor 56 for reversing the rotation thereof, returning the gear wheel 42 and associated mechanism to zero position. Simultaneously the armature closes a switch for energizing the check-issuing mechanism as hereinafter described.

After the printing operation is effected,

rollers 77 and *78 respectively, geared r ether to cause one of said rollers to revolve in a direction opposite to that of the other. Keyed to the lower shaft 76 is a pinion 79 in mesh with a verticall disposed rack 80 slidably supported by the racket 7 4 and normally held 1n a raised position by yirtue of a rin 80. The lower extremity of the rack ar 18 formed as the core of a solenoid 81, which, as will behereinafter fexplained, when energized effects a down- ;ward movement of the rack bar 80. Secured.

to the bracket 74 is a check-cutting member, Dositioned in a plane tangentially with the iuncture of the two feeding rollers, and comprising a "knife member 82-pivotally secured at one end to the bracket 74, while the other end is normall held in a raisedposition by reason of a coiled spri 82'. Referring to Figs. 3 and 12 it will be noted, however, that provision has been made fpr means whereb the solenoid may be energized until the me bar has completed itsdownward movement adapted to engage .a trip member 84 ivoted lb an insulating member supported y said bracket 74. A switch lever 85 is pivotally mounted 11 has one on provided with a contact point, preferably of platinum, adapted to engage ;a contact screw 86,but normally held out of engagement therewith by reason of a springpressed plunger 87 engaging the o posite and longer end of the lever 85. e tri member 84 is connected to the plunger 8 by means of a piri-in-slot connection and 1's obvious that as the rack 80 is moved downwardly from its normal position (see FIG 12), even to the slightest degree, the arm 83 will en age the trip member 84 which will withdraw the plunger 87 from engagement with the lever 85, thereby rmitting the contact end of the lever, y reason of a coiled spring 88, to. engage the contact screw 86. Pivotallyii- -suported by the insulati member is trip ever 89, one arm of WlllOl'l is in the path of travel of a fi er 90 carried by the upper end of the rack ar, and the other end thereof engaing the under side of the longer arm of the ever 85. Thus, after the rack has moved its full stroke downward, the fin er 90 engages the end of the trip lever 89 which causes the longer end of the lever 85 to be raised and retained in that position by to sever the stripgofpaper from roll t'othe rack bar 80 is an 83' n said insulating member and means of the plunger 87 to break the circuit for energizing the solenoid 81 and associated mechanism.

I Suitable means for inking the type may be employed, the embodiment shown herein being su'fiiciently adaptable to facilitate in an eflicient operation of the machine. As shown in Fig. 13,- a plurality of guide rollers 92 aremounted' upon the framework, and passing around these rollers is an inked ribbon 93 which passes over the type bars and under the paper strip. Adjusting means such as shown at 94 may be employed to regulate the tension of the ribbon. Secured to one of the rollers is a ratchet and pawl 95 adapted to be engaged by a dog 96 carried by the gear wheel 42, whereby the ribbon is slightly moved over the printing discs upon every revolution of the gear wheel.

The mechanism for supplying the strip of paper 102 for the tickets comprises a reel 103 mounted on the scale frame and carrying a roll of paper guided over idler rollers 104, thence passing over printing wheels 57, between feed rollers 77 and 78, and under the knife '82, which severs the strip, the cut and printed ticket being guided by chute 105 to receiving pan 106 mounted on the column 2 of the scale.

In order that the operating mechanism may be automatically reset for the next weighing operation it is necessary to again change the circuits or rather set the polechanging device to its original position. To accomplish this inan eflicient manner (see Figs. 3 and a trip lever 97 is pivoted to the frame 74 and .normally urged downwardly by a spring 97, one end thereof being pivotally connected to the trip 7 3 while the other end engages a latch 98 formed with a shoulder upon which the trip lever 97 rests after therotation of the motor has been stopped and the poles reversed. A dog 100 is keyed to the shaft and as the gear approaches the zero position of the scale on its return movement the dog 100 engages the latch 98 and releases the trip lever, causing the trip 73 to rise, changing the poles to the original condition.

VVhile it will be apparent that the illustrated embodiment of my invention herein disclosed is well calculated to adequately fulfill the objects and advantages primarily set forthi, it is to be understood that the invention is susceptible to variation, modification and change without departing from the spirit and sco of the invention as set forth in the subjoined claims. it
