DOUBLE PAPER FEEDING MECHANISM Fon CASH REGIsTERs Harold W. Clark, Alliance, Ohio, assigner to The McCaskey Register Company, Alliance, Ohio, a
corporation of Ohio Application August 6, 193s, serial No. 223,500
s claims. (el. 1er-13s) The invention relates to cash registers and similar machines and more particularly to paper feeding mechanism for feeding a double paper strip so as to provide a record or detail strip to be rewound in the machine as in usual and ordinary practice and also a receipt or ticked strip providing a ticket or receipt which may be torn off and given to the customer with each transaction.
It is desirable that cash registers and similar machines be provided with double paper strips for recording transactions, one strip forming the usual record or detail strip which is automatically rewound within the machine so as to be inaccessible to the operator, the printed portion of the other strip being adapted to be torn or cut yoif after each transaction providing a receipt to be given to the customer.
It is known that attempts have been made to provide paper equipment for producing the above results by passing two strips of paper to printing position independently of each other and at distances substantially at right angles to each other,
- but such machines require considerable additional mechanism. l
Attempts have also been made to provide paper equipment for producing these results by passing two superimposed strips of paper upward between the printing mechanism and the platen roll, but such machines require complicated mechanism for feeding the receipt strip more rapidly than the record or detail strip.
The object of the present improvement is to provide paper feeding equipment for cash registers and similar machines which overcomes the objections to the type of paper feeding mechanism above referred to and which is simple and inexpensive in construction and eicient in operation and which operates without waste of paper in either the record strip or the receipt strip.
An important object of the invention is to provide such a paper feeding equipment in which the record or detail strip and the receipt or ticket strip are simultaneously fed upward between the printingmechanism and the platen roll to printing position and then advanced to the position where the printed ticket or receipt may be torn off after which both strips are automatically and simultaneously fed backward to printing position for the next printing operation so as not to produce any undue space between different transactions, thus, avoiding waste of `paper in either strip.
A furtherobject is to provide means operated lil.
SIL
by the operation of the total key for advancing both strips to position for tearing off the receipt or ticket from the receipt strip and then returning both strips together to the printing position before the next transaction is printed.
Another object is to provide means for simultaneously printing each item upon both strips by means of double inked ribbons.
The above objects together with others which will be apparent from the drawings and following description maybe attained by constructing the improved paper feeding equipment in the manner illustrated in the accompanying drawings in which- Figure 1 is a sectional elevation of the improved paper feeding equipment showing thev parts in the position they assume during the operation of the machine to record a total,
Fig. 2, a similar view of the paper feeding equipment showing the parts in the position they assume at the completion of each transaction with the paper strips in the tear-olf position and the printed end of the receipt or ticket strip ready to be torn from the strip;

Similar numerals refer to similar parts throughout the drawings.
The invention is shown as applied to a Mc- Caskey cash register of the general type disclosed in Johantgen Patents No. 1,306,112 and No, 1,336,840, the general adding machine structure being substantially as shown in said patents and therefore the same will be describedonly briey herein, reference being made to Said Jotrolled irlV customary manner by the usual de-V pressible amount keys I9, and if desired, any required arrangement or combination of code keys (not shown), and the usual item total key II and daily total key I2.
As in usual practice, the main shaft (not shown), may be operated either by a hand lever or the usual motor key for operating th'e machine after the proper keys are depressed for each item to form the usual adding operation and to operate the type bars I3 in usual and ordinary manner to record each item or total as the case may be, all in usual `and well-known manner.k y
For the purpose of the present invention the link I4 may be indirectly connected to the main shaft of the machine in any usual and wellknown manner and arranged to be moved from the. position shown in Fig. 2 to that shown in Fig. 1, and then returned to the position shown in Fig. 2 during each .operation of the machine to record an item or total of a transaction.
This link I4 is connected to and operates the paper feeding equipment through the T-shaped lever E5, which ispivoted as at I6 upon a stationary portion of the frame I1 of the machine, the rear end of the lever I4 being pivoted as at I8 to the upwardlydisposed arm I9 of said lever. The forward end 20 of the T-shaped lever I5 is pivotally connected at 2| to the lower end of an operatingpawl 22, which engages the toothed wheel 23 upon the shaft 24 of the platen roll 25 to rotate said platen roll step by step in a counter-clockwisedirection as viewed in Figs. l to 3 and 7. Y
The rear end 26l ofthe T-shaped lever ispivotally connected at 21 to the .lower end of the slotted rack plate 23 and a pull spring 29 is connected at` opposite ends to the plate 28 and the edge of the plate v28 near the upper end thereof for cooperation with the Ytoothed wheel 23 as will be later explained, and a substantially .vertical slot 3| Vis formed in the upper portion of said plate, the upper end portion of the slot being divided byra depending finger Sia, and a stud 32 fixed upon the frame I1 or other stationary portion of the machine is located through said slot. A cam plate 33 is pivoted as at 34 upon the plate 28 and normally urged into contact with the stud 35, upon ysaid plate, by means of the pull spring 36 whereby the arcuate upper edge 31 of the cam plate is normally located, at a point slightly spaced below the lower end fof the depending finger 3Ia. v
v A pull spring 38 may be connectedat one end to the'stud 32 andY atthe other end tothe brake pavvll 39 which ispivoted atv its lower end as at 40 tothe frame I 1 or other stationary portion of themachineand provided at its upper end with a .rol 1er or stud 4I adapted to engage in the to al depending bracket 44- fixed Vupon the iframeor other statienarviportion-ofVv the lmachine and Y is provided intermediate its ends with a grooved fili roller 45 adapted to ride upon the arcuate forward edge 46 of the slotted rack plate 28, the lower free end of said lever being bent forwardly as at 41.
A rocker arm 48 is fixed upon the rocker shaft 49 and has a grooved roller 50 upon its free end adapted to ride upon the bent lower end 41 of the lever 42.
On the other side of the machine, as shown in Fig. 9, the rocker shaft 49 has an upright rocker arm 5I xed thereon and pivotally connected at its upper end as at 52 to one end of link 53, the other end of which is pivotally connected as at 54 `to the upper end vof a T-shaped lever 55 pivoted as at 56 upon the frame or other stationary portion of the maohine, the angular arm 51 of said leverk being pivotally connected as at 5B to a bar 59 which is supported at its other end by the bell crank lever 60 to one end of which the bar is pivotally connected as at 6I.
The bell crank 60 is pivoted as at 62 upon the frame of the machine and the lower arm thereof is pivotally connected as at 63 to one end of a link 64, the other end'of which is pivotally connected as at 65 to the lower end of the T-shaped lever 55. Y
A pull spring 66 is connected to the forward end of the link 64 and to a stationary portion of the frame to normally hold the parts in the position shown in Fig. 9.
The item total key II and the daily total key I2 are each provided with a stud 61 overhanging the upper edge of the bar 59 whereby a depression of either one of these total keys will cause the T-,shaped lever 55 and bell crank 60 to swing forward or counter-clockwise upon their pivots and through the link 53,` the rocker arm 5I and rocker shaft 49 will'be rotated counter-clockwise swinging the Vrockerrarm 48 upward from the position shown in Fig. 3 to that shown in Figs. l and 2.
The detail or record strip D and the receipt o1' ticket strip R are wound double upon a stock roll S carried upon the usual spool 68 journalled upon a spindle 69 and as the strips are withdrawn from thestock roll they are passed down below and around the yplaten roll 25, as shown in Fig, 7, and then upward over the front of the platen plate 10 and beneath the tear-off plate 1I, the detail strip continuing upward over the platen plate then over the top of the stock roll S and downward to the spool 12 upon which it is rewound as in usual and ordinary practice, said spool being preferably connected by a chain 13 or the like with the platen roll 25 as in usual manner so as to automatically wind said detail stri) upon the spool `12 as the machine is opera e An ink ribbon 14 of usual and ordinary con struction is located between the two paper strips on the frontside of the platen roll and the 'second ink ribbon 15 is located between the receipt strip R and the type bars I3, each of Vthe ink ribbons operating as in usual and ordinary practice, whereby with each operation of the printing mechanism the same item or total is printed simultaneously upon both Apaper strips.
Inthe operation 'of the machine `as a 'total is recorded, after each transaction, the parts are in the position shown in Fig. r2. The 'transaction just recorded is indicated upon the receipt strip R at 16 in Fig. 4. The upper end portion 11 of n the receipt strip, containing ,this transaction, is T5 then -torn off upon the Atear-off plate 1I.
After the next item is placed in the machine and the main shaft operated to record the same, the T-shaped lever I will be swung from the position shown in Fig. 2 to that shown in full lines in Fig. 3 raising the slotted rack plate 28.
Since the teeth of the rack plate 28 arevin mesh with the toothed wheel 23 during this upward movement, the wheel 23 and platen roll 25 will be rotated backward, or clockwise, by this upward movement of the rack plate, moving the paper strips D and R back to the position shown in Fig. 5 so that the rst item of each transaction will be printed upon the detail strip just a short distance below the total of the preceding transaction, as clearly shown in Fig. 5.
During this upward movement of the rack plate 28, the stud 32 will ride out of the vertical slot on the left side of the finger 3|a, and over the curved upper surface 31 of the cam plate 33, which is held against downward movement upon its pivot 34, by contact withY the stud 35.
At this point the spring 66 (Fig. 9) will, through the linkage 64, 55, 53, 5I, oscillate the rock shaft 49 in a clockwise direction, as viewed in Fig. 9, and counterclockwise as yviewed in Figs. l, 2 and 3, and through the rocker arm 48 and roller thereon, will swing the lever 42 back to the normal position as shown in Fig. 3.
It will be clear that this action of the lever 42, will, through the roller 45 thereon, swing the rack plate 28 to the left, upon its pivot, so that the right side of the slot 3l will bear against the stud 32 as the rack plate reaches the upper limit of its movement, as shown in full lines in Fig. 3.
In this position it will be seen that the teeth 38 of the rack plate are moved to the left of, as well as above the toothed wheel 23. As the operation of the machine continues the rack plate 28 will then move downward to the dot anddash position shown in Fig. 3, the roller 45, on the lever 42 continuing to hold the right side of the slot 3| against the stud 32, so that the teeth 30, upon the rack plate 28, .will remain out of engagement with the toothed wheel 23, so that as the item is printed the usual line spacing only is performed.
As each succeeding item of a transaction is recorded the rack plate 28 will move up and down between the two positions shown in Fig. 3, without engaging the toothed wheel 23 by the teeth 30, the wheel 23 being merely advanced one space for each item by means of the pawl 22.
When the total for each transaction is taken, the total key Il is depressed and the main shaft is operated in customary manner. The depression of the total key will rotate the levers and counter-clockwise, and through the link 53 and lever 5I the shaft 49 will be rotated counterclockwise, as viewed in Fig. 9.
This will swing the rocker arm 48 to the raised position, as shown in Figs. 1 and 2, and as the rack plate 28 moves upward, from the broken line position shown in Fig. 3, stud 32 will ride down along the right side of the finger 3|a, and along the right side of the cam plate 33, and as the cam plate passes out of contact with the stud, the spring 29 will pull the rack plate forward, or to the right as shown in Fig. 1, with the teeth 38 in line to engage the toothed wheel 23 on the next downward movement of the rack plate.
As the totaling operation is completed the rack plate 28 will move downward from the position shown in Fig. 1 to that shown in Fig. 2. The lower edge of the cam plate 33 will contact the stud 32, as the rack plate moves down, swinging said cam plate upward upon the pivot 34, and against the pull of the spring 36, so that the stud. 32 will ride against the left side of the slot 3|, from the bottom to the top of said slot, and being received on the left side of the finger 3|a, as shown in Fig. 2.
During this downward movement of the rack plate the platen will be rotated counter-clockwise, as viewed in Fig. 2, so as to'move the detail strip and receipt strip to the position shown in Figs. 2 and 4, when the receipt portion 11 of the receipt strip may be torn from the strip, upon the platell, and the machine is ready for the next transaction, the operation continuing as above described.
vWith the parts in the position shown in Fig. 2, which illustrates the condition after a total taking operation, it should be noted that the spring 66, acting through the rocker arm 48, and roller 45 upon the lever 42, is pressing the left side of the finger 3 la against the stud 32.
As the slotted rack plate 28 is again raised during therst portion of the cycle of operation, the spring assists the cam edge 3l' of the cam plate 33 in moving the rack plate 28 to the full line position shown in Fig. 3, and maintains the rack plate in that position whenever the same is raised with no total key depressed.
It should also be noted that on a total operation the rocker arm 48 is raised while the rack plate 28 is still in the dotted line position shown in Fig. 3, but movement of the rack plate, by the spring 29, to the position shown in Fig. 2, will be prevented by the linger 3Ia and cam plate 33 until the rack plate raised suiiiciently to assume the position shown in Fig. 1, at which time the teeth 38, upon said rack plate, have passed above the pinion 23 on the platen roll.
