CASH REGISTER.

Application filed June 29, 1923. Serial No. 648,4??-

This invention relates to cash registers and is shown carriedout in connection with a machine of the type shown in the E. J. Von Pein applications, Serial Nos. 458,510, and 590,373, filed April 4, 1921 and September 25, 1922, respectively. I

An object of this invention is the provision of means for printing and issuing one or more tickets in-a strip during one operation of a machine of the key-operated ype Another object of the invention is to embody in such a machine mechanism for printing the tickets as they are issued,vthere-.

by eliminating the necessity of carrying a large number of valid tickets which might at any-time be subject to theft and use.

Another object is to provide manipulative means for controlling the number of tickets to be issued and which automatically disables the driving means after the predetermined number of tickets are issued.

Another object of this invention is the provision of a common driving means to operate the key coupler and printer independently of the item keys with an interlock between the key coupler and printer,

With these and incidental objects in view, the invention consists of certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred form of embodiment of which is hereinafter described with reference to the drawings which accompany and form part of this specification Of said drawings:

Fig. 1 is a plan view of the right hand end of the machine with parts omitted for clearness.

Fig. 2 is a detail view of the driving connection between the key coupler and the cam shaft.

Fig. 3 represents two tickets in a strip as printed by the machine.

Fig. 4 is a transverse section of the machine taken to the left ofthe totalizer.

Fig. 5 is a detail sectional view of the totalizer.

Fig. 6 is a detail elevation of the ticket control mechanism together with the motor control with parts omitted for clearness.

Fig. 7 is a perspective view showin the handle of the ticket control lever an the index on the casing.

Fig. 8 is a side elevation of the printer.

Fig. 9 is a detail View of a part of the key 21. The amount keys 20 comprise two members, a front manipulative member 22, and a rear member 23 adapted to be coupled to a key coupler 24 in the usual manner. Both .members are pivoted upon a rod mounted in the side frames of the machine. The motor or control key 21 is mounted upon the end of the rod projecting through the right side frame.

Tn machines of this type the members 22 and 23 generally heretofore have been made integral to drive the key coupler by depressing the keys. In this machine the manipulative member 22 when depressed functions to stretch a spring 25 (Fig. 4) secured to the frame and to a lever 26 pivoted to said member, .and provided with a pin 27 projecting over said member and in engagement therewith, into the plane of a forward extension 28 of the member 23. After a manipulative member is depressed, spring pressure will be exerted on the extension 28 of its corresponding rear key member to urge the rear end thereof toward the key coupler. As the key coupler is raised, the rear key member is also raised by the spring 25. a sufficient distance to efiect a coupling connecwith the item printing wheels 36 (Figs. 1 and 8) by a tube line 37 to set up the amounts, represented by the keys depressed.

The key coupler 24, before referred to. is pivotally mounted in the side frames and rests upon the rear ends of the keys. The right hand end of the key coupler 24 (Fig. 2) carries a roller 38 which cooperates with a slot in a driving member 39. The driving member rotates a shaft 40 in the usual manner, as is well known in the art.

The amounts represented by the keys depressed are also entered in a totalizer mounted in a frame 41 (Figs. 4 and 5) pivotally supported on trunnions 42 supported in a frame member of the machine.

The totalizer is of a well known standard form for this type of machine and is provided with totalizer elements having pinions 43 engaging with the actuators 31 at the roper time to enter the items registered y the keys.

Interlocking and control features.

The front key members 22 are held depressed temporarily by spring controlled angle plates 50 which snap over projections 51 thereon. There is one plate 50 for each group of keys. These plates are supported by arms of levers 52 rotatably mounted on a rock shaft 53. The lower ends of these levers bear against pins carried by arms 54 pinned to the rock shaft 53. The plates 50 are normally held in the position shown by springs secured to the lower ends of levers 52 and to a rod carried by the frame of the machine. The shaft 53 is supported in the side frames and is rovided with an arm 55 (Figs. 4 and 6) whlch rocks the shaft to release the depressed keys before an entry of items is effected to make corrections in the amount set up. By means of a lever 56 freely mounted .on a shaft 57 and carrying a pin 58 engaging the arm 55, the depressed keys may be released by the operator.

The motor or driving means and the controlling stops and switch are of the same construction as those shown in said applications and in Letters Patent of the United States to Kettering and Chryst, No. 1,144,418, granted June 29, 1915. Only the clutch member 59 (Fig. 6) of the motor is shown in this application. A lock lever 60, similar to the lock lever in said patent releases the motor when moved counter-clockwise by a spring 61, and arrests the motor when moved clockwise by an arm 62 rotatable with a shaft 63.

The spring 61 is connected to the frame and to a slidably mounted link 64 connected to the arm 55. The link 64 is normally held in the position shown in Fig. 6 by a springactuated catch 65 engaging behind a stud 66 on the frame of the machine. An arm 67 65 (Figs. 6, 10 and 11), also spring-actuated,

is provided with a lip 68 in engagement with the end of the hook portion of the catch 65. A catch member 69 pivoted at 81 to a plate 80 is provided with a laterally directed fin 71 in alinement with the lip 68. This catch member is also provided with a shoulder 72 to cooperate with the stud 66. When the catch member 69 is moved downward, the catch 65 is released and the lock lever 60 is removed to releasing position. When the lock lever is returned to locking position 4 the parts move back to the position shown in Figs. 6 and 10. A tension sprin 73 holds the catch against the stud 66. All of when in its home position. The key is nor-- mally held in home position by a spring 83 connected to a pin in the key and to the frame.

When the motor or control key is depressed the shaft 57 is rocked to move the catch member 69 downwardly to release the motor. When the motor releasing mechanism is returned to home position a spring 84 returns the shaft 57 and catch 69 to home position.

It, is desirable to prevent the release of the depressed item keys by the lever 56 after the motor or control key is depressed. For this purpose the item keys are provided with projections 85 (Fig. 4) which cooperate with a locking member 86 supported by arms 87 secured to the shaft 57.

When the motor or control key 21 (Fig. 6) is depressed, the pin 82 secured in the control ke will engage the plate 80 and rock the s aft 57 in a clockwise direction, Fig. 6, and counter-clockwise (Fig. 4) a sufiicient distance to swing the locking member 86 over the projections 85 of the keys depressed, and under the projections of the keys not depressed. In the last mentioned position all item keys are locked against manipulation. Should an item key be but partially depressed, the locking member 86 would engage the end of the projection 85 and prevent the depression of the motor or control key 21 (Fig. 6).

The key members 22 are also provided with portions 93 for cooperation with plates 94 pivoted in a cross frame member 95 to prevent a simultaneous depression of a plurality of item-keys in the same denominational group.

Secured to one part of the motor clutch member 591(Fig. 6) is a pinion 96 (Fig. 8) engaging a gear 97 mounted on the shaft 63. When the motor is released by depressing the motor or control key it will drive the gear 97 one complete cycle for each ticket issued by the printer.

Secured to this gear is a disc 98, having a cam race '99 cooperating with a roller 100 carried on a pitman 101 which is bifurcated at its lower end to be guided by the shaft 63, and the upper end is pivoted to an arm 102 pinned to the trunnion of the key coupler 24. As the shaft 63 rotates, the key coupler will be given a rocking motion to operate the rear key members, previously described.

Pivotally connected to the pitman 101 isa link 103, having an elongated opening 104: engaging a stud 105 mounted in the arm 55. As the pitman moves toward the right,

pressed key members 22 to rise slightly so that the plate cannot again enter the slot above the projection 51. The keys are retained in the last mentioned position by the locking member 86 which will be in a position over the projection 85 to retain the depressed keys until near the end of the operation as previously described. elongated opening 104 permits the operation of the lever 56 to release depressed keys without affecting the key coupler.

Secured to the gear 97 and cam disc 98 is a'disc 110 and a partialgear 111 which cooperate with a disc 112 and gear 113 respectively to operate the printing mechanism. The last mentioned disc and gear are I secured to a shaft 114.

The key coupler operating cam and printer driving mechanism are so timed that the printer is inoperable while the key coupler is being raised to its upper position where it remains while the printer is operated. Again the printer becomes inoperation of the machine. But when there are two or more tickets to be issued the spring 61 will cause the arm to move counterclockwise as soon as the arm 62 disengages from the pin 115, and allow a continuous operation of the driving mechanism.

The means for controlling the number of tickets issued, consists of a lever 116 (Figs. 6 and 7) pivoted at 81 to the plate 80. This lever projects through a slot 117 in the casing of a machine and has a pointer The 118 cooperating with numerals in positioning the lever to predetermine the number of tickets to be issued.

The lever has a downwardly extending portion 119 having ratchet teeth formed on its lower edge which normally are disengaged from a spring actuated retaining pawl 120, and an actuating pin 121 mounted in the arm 67. After the lever 116 is moved into the desired position, where it is temporarily retained by friction or otherwise, the motor or control key is depressed which causes the plate 80 to'move downward and lower the lever 116 into engagement with the retaining pawl 120 and actuating pin 121. Referring to Fig. 6 the lever is in position for issuing one ticket. As the catch is released from the pin 66, as previously described, and the link 64 moves toward the right; the pin 121 will assume a position to the right of the ratchet plate 119 and as the link or together with the catch 65 moves to the left the catch 65 will return to its normal position as shown. With the lever 116 placed in the 2 position on the index, the actuating pin 121 will first engage with the second ratchet tooth from the right, and as it moves toward the right, will during the first operation of the machine move into engagement with the first ratchet tooth, and during the second operation of the driving mechanism it will disengage from the ratchet and when it again moves toward the left will be free to move upward, allowing the catch 65 to assume its normal position in front of the pin 66 and retain the arm 66 in'position to stop the motor. And so when a greater number of tickets is required the lever will be progressively returned to normal position being retained in each progressive position by the pawl 120.

Referring to Fig. 3 there is shown a strip of two tickets as printed by the printing mechanism shown in Fig. 8. These tickets are detached from a strip 125 which is fed from a supply roll (not shown) around guide studs and between a platen bearing member 126 and the type wheels 36, date and consecutive number wheels 127 and electro plates 128 and 129.

The strip 125 is fed forward at each operation of the printing mechanism by the usual feed rollers 130 and 131. Operatively connected to the feed roller 130 is a gear and ratchet feeding mechanism 132 (Fig.

9) which is actuated by a segment lever 133 tached from the strip upon a severing plate 138 supported by the casing of the machine.

The printing mechanism will be continuously operated a number of times equal to the number of tickets required.
