Cash register mechanism The cash register operating mechanisms will not be claimed in this application, being the subject matter of my co-pending application, Serial No. 689,656 led September 15, 1933, but will be brieiiy described in order to better comprehend this invention. For a full disclosure of the cash register mechanism reference is made to my above co-pending application.

The cash register mechanism instead of being mounted within a cast frame is mounted and carried between right and left side or end plates i which support the entire mechanism and are maintained in spaced relation by tubular members 3 and by various shafts of the cash register mechanism. This construction not only facilitetes assembly, inspection, and repair of the machine, but reduces weight and also cost of production.

The cash register operating mechanisms include two rows of depressible keys 4 of the necessary denominations and numbers in each denomination. The keys are journaled on a cross shaft i3 secured to end plates I and are urged clockwise about shaft 6 by springs 1, the movement of the keys being limited by cross bar 8. Each key has a rearwardly and upwardly extending arm 9 which engages a hollow cross shaft II carried at each end by one arm of full stroke lever I2 secured to shaft 6 adjacent each end thereof. The shaft II and full stroke levers I2 constitute a universal bail, the rocking movement of which is restricted by means of arcuate slots i3 formed in the side plates and through which the ends of shaft II project. Levers I2 which are constantly urged clockwise by springs I4 terminate at their upper ends in full stroke sectors IG engageable by pawls II to insure a full stroke being made each time levers I2 are oscillated.

A key coupler I 8 extends across substantially the entire machine, being journaled upon shaft iI and is provided with a rearwardly and downwardly extending lip I9 adapted to engage lugs 2| extending upwardly from each of the key levers. The coupler is urged clockwise by a pair of springs 22 so as to normally urge lip I9 into the path of movement of lugs 2I by means of which all keys may be latched to the coupler and all partially depressed keys or latched keys are carried downwardly upon full depression of any one key.

The upper end of each key lever terminates in a differential cam slot 23, the diiierent slots being of diiierent inclinations. 'Ihe keys with their slots constitute means for diierentially positioning the register 24 as well as the indicator tab magazines 26. The register 24 may be of any desired type and is illustrated as of the type shown in the Horton Patent No. 1,326,504, issued December 30. 1919. There is a register section for each denomination of keys and a pair of indicator tab magazines for each denomination of keys.

The keys of each section or denomination of keys through their slots 23 engage a bail 30 eX- tending across the corresponding denomination of key levers and carried by spaced arms 3| journaled on shaft 32. Bail 30 enters the forked end of arm 33 of a crank also journaled on shaft 32 for positioning the tab magazines as described in my co-pending application Serial No. 689,658, iiled September l5, 1933, to which reference is made for details of the mechanism involved. The crank also has a second arm 34 projecting downwardly therefrom for indexing the registers as explained in my above copending application. The second arm in normal position also engages a restoring bail 35. Bail 35 extends across the entire width of the machine and is carried by crank arms 3l also journaled on shaft 32. The latter crank arms 3l have an integral arm 38 having a cam groove 3S into which project studsy 392L carried upon upwardly and rearwardly extending arms ia of the full stroke levers l2.

From the foregoing it will beV apparent that upon depression of keys 4, bail 3! and crank arms 34 are diiferentially rocked about shaft 32 in accordance with the key depressed to index both the tab magazines and the register and to actuate the restoring bail 35 which serves positively to return magazines 25 to normal position at the complet-ion of each operation or return of each key.

It will be understood that there is a bail 3o and a crank arm 34 for each denomination of keys, that is, one for the dimes, one for the cents and one for the dollars, whereas there is one return bail 36 for all of the keys.

I ndexing of register sections The accumulating register has a corresponding section for each denomination of keys and bails 3B. Each section of the accumulating register is connected to its corresponding crank arm 34 by a link 40 having one arm attached to the lower end of crank arm 34 and its other arm attached to one end of a toggle link 4l by a pin 4Ia which constitutes the intermediate pivot of the toggle links. The operation and control of each section of the accumulating registers is the same, and therefore, the operation and control of only one section will be described. Y

The forward end of toggle link 4l is connected to an actuator or rack 42 pivoted at 43 to the accumulator register frame 44, the rack being normally urged clockwise about pivot shaft 43 by a spring 46,and the movement of the rack being limited by a stud 4l projecting through an arcuate slot 48 formed in frame 44. Rack 42 being connected by means of links 4l and 4@ to arm 35i,V is diiferentially moved a varying distance at each operation of the machine in accordance with the key or keys depressed in its section or denomination.

Rack 42 is in constant mesh with a gear 49 journaled upon a shaft l Xed to end frame 44. Gear 49 is fixed to a plate 52 which carries a spring pressed pawl 53 in position to engage spaced lugs or teeth 54 carried by a gear 55. Depression of a key rotates gear 49 through rack 42 which gear rotates pawl 53 clockwise, which upon return stroke of the key and gear turns in a counterclockwise direction, engages a lug 54, and rotates gear 55 counterclockwise. Gear 55 in In normal. or

returned position pawl 53 is always at the top as shown in Fig. 3 so as to engage the uppermost lug 54. 1t will be understood that the foregoing mechanism is repeated for each register section as previously stated. If a No. l digit key is depressed, pawl 53 will upon depression and just prior to return stroke, assume the position shown in Fig. Ll, in which it israbout to engage a second lug 54a to rotate gear 55 and register wheel 24 one digit, as shown in Fig. 4.

In order to positively insure pawl 53 of engaging the proper lug 54 it is desirable to move pawl 53 to a point well beyond the lug which it is to engage upon the return stroke, that is, it is desirable to give pawl 53 a lead in clockwise rotation over the variable distances it has to move in counterclockwise rotation.

Each link 46, of course, moves varying distances with the arms 34 to which they are attached in accordance with the key of its order which is depressed. Each movement forward and backward is through the distance necessary to move the tab magazine from normal position to its new indexed position. To impart a constant additional movement or lead to the register indexing means or to a portion of the driving connections., link 40 is provided at its forward end with a cam slot 66 slightly arcuate during the major portion of its length and terminating at its forward end in an upwardly inclined portion Si (Figs. 3 and 4). Cam groove @El is engaged by a pin 62 carried by a yoke S3 mounted for horizontal sliding movement on shaft 43 for reasons which will later appear.

In normal position pin 52 (Fig. 3) rests in the upper end El of the cam groove 6D in which position the toggle link 4l is slightly below horizontal position. Upon depression of any key and resultant forward movement of link 4o, pin 62 causes a slight raising of the forward end of link 4,0 and of the rear end of link 4l to the position shown in Fig. 4. The raising of toggle links 4B and 4l from Fig. 3 position to Fig. i position imparts a slight additional forward movement to rack 42 over the movement of link 40 necessary because link is indexed only the exact distance required to positionA the indicator tabs at each operation of the machine. This additional movement to rack 42 is constant and not cumulative and is a lead which insures. that the pawl 5,3 will clear the stud 54 which it is to engage upon return movement asis shown in Fig. 4. in this ligure a number 1 key has been depressed and the pawl upon return movement is intended to engage the first lug 5,14,a clockwise of the upper lug 54 and as can be seen pawl 5,3 is resting upon the second lug 54b clockwise of the upper vertical lug 54, thus insuring that it will engage the first lug 54a upon return or counterclockwlse movement of pawl 53.

The major and substantially horizontal portion of the groove Sil is slightly arcuate to compensate for the arcuate movement of arm 34 and insures substantially horizontal movement of tog,- gle link 4l after pin 52 has cleared the upper portion El of groove E0.

Non-add control ogf the register Occasionally an amount is paid out of the cash register and while it is desirable to have an indication of the amount paid out and, in fact, to enforce an indication being made of the amount given Gut,A the amount so paid out should not be accumulated in the register.

For non-adding or paid-out transactions a special paid-out key 'l0 is provided. This key is locked to the preset key H by means of a locking pawl l2 pivoted to the paid-out key and a stud 'i3 projecting from the preset key so that it cannot be depressed unless the preset key is depressed. The preset key is connected to the universal bail and the key coupler so as to rock the latter to preset position at which position the coupler is in the path of movement of projections 2l whereby thereafter any keys may be latched to the key coupler. The paid-out key also has a forwardly projecting iinger 'it extending forwardly from its rear arm 9 in posi tion to contact the return bail 36 so that the paid-out key cannot be depressed beyond preset position, but inasmuch as the machine must be in preset condition before the paid-out key can be depressed, one or more digit keys must be depressed after depression of the paid-out key to release the machine from preset condition and to indicate the amount withdrawn when the paid-out key is depressed unless, course, the preset key is depressed again, which will release the paid-out key and leave the machine in preset condition.

The paideout key is coupled to yoke t3 to disengage pins t2 from cam groove dii to place the accumulating register in non-adding condition as will now be explained.

Partial depression of paid-out key 'lil causes its lower edge to engage a cam 'E5 on a lever 'l pivoted intermediate its ends at 'l'i to a brack et i8 secured to the side frame l. The upper end of lever 'it is connected to one end of a link 19, the other end of which is connected to a bail 63 and causes it to slide horizontally upon pivot shaft 43. The sliding movement is sufficient to disengage pins G2 from cam grooves 66].

When pins 62 are disengaged from cam grooves 'iii and. a key is depressed, link 4S, of course, moves forwardly, but toggle link 4l instead of moving upwardly or horizontally drops downwardly and the racks 42 being held in clockwise position by springs 46 are not moved upon movement of links 40 and toggle links di. On the contrary. links lll and 4I drop downwardly as shown in Fig. 5 and no action whatever takes place in the register.

To positively prevent any upward movement of the links when the paid-out key is depressed, a stud Bil (Fig. 6) is positioned on each or the links lli and positioned to engage the underside of studs 62 when the latter are disengaged from cam grooves ED. For instance Figs. 5 and 6 show the parts in position during a paid-out or non-add operation,v during which the studs are moved sideways out of engagement with the cam slots eil and 6|. Then when a digit key is depressed link 4l! is allowed to move downward as seen in Fig. 5 and without moving the actuator rack 42. During the return stroke of the digit key, link 4!) is moved upwards under control of lever 4i and unless some means is provided the link 4Q may move beyond its normal position to a position where the slot (iS-6I will not align with the stud 62 and which would prevent the other studs 62 and the yoke 63 from returning to normal. The use of stud 8B on each link iii is to prevent an overthrow of the links when returning to normal during a paid-out operation, by limiting against the under side of the studs 52 as shown in Fig. 6, the studs insure the proper alignment of studs 62 and slots Sil-5l just as the machine is restoring to normal during a paid-out operation. During the other operations when the studs 62 are in constant engagement with slots 60-6I the studs 8d do not perform any active function.

To insure positive return of bail 63 with its studs 62, paid-out key 'IG is provided with a bracket Si which carries a pin S2 in position to engage the underside of cam 'l5 upon raising of paid-out key lil, thus positively swinging lever 'I5 clockwise about its pivot as viewed in Fig. 2 and returning link i9 and bail 63 to normal or engaged position.

it will be apparent from the foregoing that there has been provided an accumulating register which requires very little energy to operate and which is positively and accurately actuated at operation of the keys, a lead or advance movement being given to positively insure proper engagement of the pawl with the tooth intended to be engaged in the register driving gears. Furthermore, the register may be disabled by a simple breaking of the toggle connection in the drive.

it will also be apparent to those skilled in the art that minor changes may be made in the details of the construction without departing from the spirit and scope of the invention as defined in the appended claims.
