To all whom, it may concern.-

Be it known that I, EDWARD MORIARTY, beer retailer, a subject of the Queen of Great Britain, residing at 180 North End road, Fulham, in the county of Middlesex, England,

have invented certain new and useful Imrecorded by registering-drums, so that the total amount of money which should be found in the till is represented by the said drums.

According tomy invention I provide in proximity to the inner ends of the aforesaid key-levers and 'in a position to be operated thereby a number of plates formed with inclined or cam-shapededges or portions and hereinafter referred to as cam-plates, aseparate cam-plate being provided for each of the aforesaid key-levers. -Thesecam-plates are arranged'in series, each series being preferably carried by a rocking bar or shaft. The

, cam-plates of each series are of different contourthat is to say, their shape is such that when the key-levers are actuated the extent of rocking movement imparted to the said rocking bar will be greater or less, according as a key-lever representinga higher or a lower denomination is actuated.

Means are provided for transmitting the movement of the cam-plates to the registeringdrums, which are caused to move angularly to an extent equivalent to the amount of movement which the said rocking bars receive from their cam-plates when the latter are actuated by the key-levers. Means are also provided for transferring from one registering-drum to the next of higher denomination the amount beyond that which can be registered on the drum of the lower denomination', such means comprising a movable arm carried by each of the rocking bars, which arm is released and permitted tomove independring-lever which the drum operates.

ently of the rocking bar when a transfer is to be made, means being also provided whereby the extent of movement of said movable arm is controlled. Means are also provided whereby the extent of movement of the aforesaid rocking bars cannot exceed that which is necessary for effecting any particular recording stroke, no matter how sharply or suddenly the key-levers may be struck in actuating them. For this purpose I employ stop-pieces carried by additional rocking bars, having cam -plates which are in form duplicates of the cam-plates on the main rocking bars with the exception that they are arranged in reverse order. Both of these sets of cam plates and their rocking bars are adapted to move simultaneously, but in opposite directions.

In order'that my invention may be clearly understood, I will proceed to describe the same more fully with reference to the accom panying drawings, which illustrate a moneytill of the kind hereinbefore referred to provided with my improved counting or adding apparatus.

Like letters of reference indicate similar parts in all the figures.

A A A are the key-levers, which are of the ordinary construction usual in this class of apparatusthat is to say, they consist of bars pivoted at a to the framing of the apparatus and maintained with their outer ends elevated by a rocking frame A hinged to'a transverse rod A and normally kept in its depressed position by a spring A (see Fig. 8,) connected, respectively, to the rocking frame and the framework. Other springs, as A, Fig. 3, may bear against pins, as A, on the key-levers. The said outer ends of the key-levers bear figures or other signs designating the amounts of money which the various key-levers represent. In the example illustrated the key-levers are arranged in three series or divisions-viz., the key-lever A, representing five cents, the key-levers A, representing, respectively, ten, twenty, thirty, forty, fifty, sixty, seventy, eighty, and ninety cents, and the key-levers A representing, respectively, one, two, three, four, five, six, seven, eight, and nine d01- lars. It will therefore be seen that this arrangement comprises three divisions of the key-leversone key-lever A, a series of nine key-levers A, and another series of nine keylevers A ment may be varied in any desired manner to accord with the requirements of the apparatus. The inner ends of the key levers work in vertical slots A, Fig. 9', at the back of the machine, which slots serve the double purpose of guiding said key-levers and of limiting the extent of their vertical movement.

13 B are the main rocking bars, of which there are two in the present example, one for the series of key-levers A and the other for the series of key-levers A 0 O are the additional rocking bars, arranged adjacent to and parallel with the aforesaid bars B. These bars 13 and Care each provided with pivots b and 0, respectively, at their ends, which pivots are mounted in suitable bearings forming part of the framing of the apparatus.

D I) are the cam-plates carried by the main rocking bars B, and E E are the cam-plates carried by the additional rocking bars 0.

F F F F F are the registering-drums, the drum F bearing alternately the figures 0 and 5 and the drum F bearing the figures O, 10, 20, 30, 40, 50, 60, 70, 80, 90. The drums F F and F bear figures to represent units, tens, and hundreds, respectively.

The series of cam-plates D depend from the rocking bar B and are connected thereto, so

that they all move simultaneously therewith.

nation of the series of key-levers A be operated the said rocking bar B will be rocked to a definite predetermined extent; but if another key-lever of the same series be operated representing a denomination, say, twice or thrice as much as the key-lever of lowest denomination then the extent of rocking movement of the said bar will be correspondingly twice or thrice as great. The two series of cam-plates carried by the two bars 13 O are so arranged that they lie side by side (see Fig. 19) with their cam-surfaces facing in opposite directions, so as to form pairs of camplates. Each of the key-levers is provided with a lateral pin a, Fig. 9, which lies immediately below the various pairs of camplates, and when the outer ends of the keylevers are depressed these pins rise and enter between the pairs of cam-plates, thereby causing them to be shifted in opposite direcrections and the rocking bars to likewise be rocked in opposite directions, as-shown by the dotted lines in Fig. 9.

Each of the rocking bars B is provided with an arm or bracket B, to which is pi-votally connected at b a movable arm B which is normally prevented from turning about its I pivot vby a locking device, hereinafter de- Obviously, however, this arrangel scribed. The said arm 13 is connected at its outer end by a connecting-rod B to a segmental rack 13, mounted on a transverserod B. This rack gears with an elongated pinion B loosely mounted on a transverseshaft B".

1 The said elongated pinion forms part of a clutch device B which in the example illustrated comprises a pair of arms having at their extremities lateral pins B", lying adjacent to the face of a registering-drum. The registeringd rum is formed with a concentric series of holes f, corresponding in number to that of the divisions or denominations which the drum bears, and with these holes the pins 13 are adapted to engage by a lateral movement of the clutch device.

B is a spring interposed between each of the registeringdrums and the said clutch devices, such spring normally tending to keep the clutch device pressed away from its adjacent drum against a stop-piece B on the shaft B The pins B of the clutch device are thus kept out of contact with the drum, although they lie sufficiently close thereto to insure their quickly engaging with the holes,

fin the drum when the clutch device is laterally shifted by the stop-piece B on the shaft as the latter is moved longitudinally by the action of a cam H. This cam is concentrically arranged with respect to the aforesaid shaft B and is connected, by means of a rod H, Fig. 17, to an arm H forming part of the rockingframe A so that each time a key-lever is operated and the said frame caused to swing about its bar A the cam will guide-pieces 77. which serve to steady the pins h h while they are being acted upon by the said cam. When one or other of the keylevers is depressed, its initial movement lifts the aforesaid swinging frame A ,which in turn imparts angular movement to the cam in the direction represented by the arrow in Fig. 17. This movement of the cam causes its cam-surfaces h, Fig. 18, to act upon the pins h which consequently slide the shaft 13 longitudinally from right to left of the machine and bring the clutch devicesinto engagement with. their adjacent drums. By the continued downward movement of the key -lever the said rocking bars are actuated and cause the segmental rack 13 to turn angularl'y to an extent depending on the denomination of the keylever operated. This angular movement of the segmental rack turns the elongated pinion and clutch device to a corresponding eX- tent, whereby the registering-drum belonging to the series of cam-plates underoperation is caused to turn a sufficient distance to effect its registering movement. By the time the key-lever has been fully depressed and the cam H has completed its movement in the direction of the said arrow the aforesaid pins h arrive in the spaces 72. of the cam H,whereby they escape from the cam-surfaces h and permit the springs B of the clutch devices to shift the said shaft B from left to right'of the machine and return it to its original position, thus carrying the pins 13 out ofengagement with the holes in the registeringdrums; Then when the key-lever is liberated and allowed to return to its original position under the action of the spring-controlled rocking frame A the cam H is by the latter shifted in the reverse direction, whereby the other cam-surfaces h of said cam operate on the aforesaid pins h By so doing they cause the shaft B to move longitudinally still farther in the direction of left to right of the machine against the resistance of a spring B whereby the pins h are positively carried completely away from the registering-drums.

I thus avoid any liability of the pins engaging with the drums during the time that the elongated pinions are being revolved in the reverse direction by their segmental racks as the latter return to their normal position under the influence of springs B O on the rocking bars B C and springs 3 on the transverse rods B As soon as the said pins escape from the cam-surfaces 71. and arrive opposite the space h of the cam the reaction of the aforesaid spring B shifts the shaft B longitudinally in the reverse directiont'. e., from right to leftso as to bring the pins h into their normal position, ready to be again acted upon by the cam-surfaces h when a key-lever is next depressed. At the same time the pins of the clutch devices are brought into the aforesaid position of close proximity to theregistering=drums,readytoimmediately reengage with the holes in said drums when a next recording operation is tobe performed. In order to prevent the aforesaid spring B from carrying the shaft B too far toward the left, the end of said spring is adapted to strike against a stop B The aforesaid registering-drums are provided with appropriate means for retaining them in any of the angular positions to which they are set by the apparatus. In the drawings I have shown the drums F and F providedwith lateral pins f whose number corresponds with the number of steps which the said drums perform in completing a single revolution. Engaging with these pins are two pawls f f, arranged contiguous to each of the drums, the pawl f serving to prevent the drum from moving in a forward direction and the pawl f to prevent it from movingin a rearward direction. -The pawlsf are car ried by a spindle f which is furnished with a spring f for causing the pawls to engage with the pins. Near one end of said spindle is a finger f which lies contiguous to a finger f carried by another spindle f". This last-mentioned spindle has a lug or projectionf", which lies in the path of an arm A carried by the rocking frame A, so that each time the said rocking frame is elevated when a key-lever is depressed the arm A acts upon the aforesaid lug or projection f and so turns the spindles f 8 and f in a direction to remove the pawls from engagement with the pins on the drums. This movement takes place immediately a key-lever commences to descend and before the aforesaid clutch devices 13 have had time to engage with the drums. The pawl f is maintained in engagement with the pins f by a springf which permits said pawlf to give way to the pins f as v the drum moves in aforward direction-tl 6.,

in the direction of the arrow in Fig. 5-but does not allow said pawl to give way'to the pins if. the drum tends to move in the oppo site direction, the shoulder f then acting as a stop.

As the drum F (which registers alternately five cents and zero) does not require to be turned more than one step at a time, I do not employ a cam-plate and rocking bar for operating it, but employ means foractuating it directly from its key-lever A. For this purpose I provide said drum with a springpawl I, Figs. 11 and 13, to engage with a ratchet t', forming part of a sleeve 11. This sleeve is provided with a radial arm 2' which is connected by a link i to the key-lever A. The drum and the aforesaid sleeve are both loosely mounted on their shaft, and therefore each time the key-lever A is depressed the said drum is caused to travel a distance of one step through the intervention of the pawl and ratchet, as is well understood. In order to prevent said drum from being unintentionally turned in either direction, I provide a spring-pawl I, which is adapted to engage with lateral pins I on the drum. The formation of this pawl is such that the tendency of the drum to turn forwardly when the keylever A is depressed causes the pins to raise said pawl; but any tendency for the drum to turn in the reverse direction is overcome by a shoulder I on said pawl.

The aforesaid movable arm 13 is, as already stated, capable of receiving movement about its pivot 12 independently of the movement it receives from the main rocking bar B. Normally, however, the said arm B is prevented from turning about its pivot by a'lockingdevice. When it is necessary for the machine to transfer the amount recorded by one registering-drum to another of higher denomination, the said locking device is thrown out of action and the independent movement of the arm B is effected bya contrivance which is actuated by the registering-drum of lower denomination. The contrivance illustrated in the drawings for releasing the said arm 13 and for effecting the independent movement thereof comprises a shaft J, Figs. 9 and 10, which is capable of sliding longitudinally and of oscillating. I It is mounted in bearings that are independent of the aforesaid main rocking bar, and at its inner end it is'provided with a crank or arm j, having an elongated slotj therein to engage with a pin 6 on the inner end of the movable arm B The outer end of the said shaft J is provided with a finger or cam piece 7' which so long as the said shaft occupies its inward position (represented by the full lines in Fig. 10) lies out of the path of a pin or projection a on the rocking frame A The aforesaid locking device comprises a plate or finger b which is pivotally connected at b to a bracket on the rocking bar B and by a spring 5 is normally maintained in a position transverse of the plane of movement of the movable arm B so that the latter cannot at such time be shifted in the direction ofsaid locking device or, in other words, cannot perform its aforesaid independent movement. The said locking device is provided with an elongated pin b, which is adapted to be acted upon by an armj on the aforesaid shaft J when the latter is caused to slide longitudinally into its outward position. By the outward sliding movement of the said shaft J the locking device is by means of the said elongated pin 5 and the arm 7' withdrawn from its restraining position, so that the arm 13 is free to turn about its pivot and to perform its independent movement. For the purpose of imparting the sliding movement to the said shaft J at the proper times, a lever K, pivoted at 70, is provided, the end K of such lever engaging with apin j on the said shaft J and the other end K lying in a position to be acted upon by pins on the registering-drum or by a device (hereinafter described) which is under the control of said pins. The aforesaid movable arm 13 is provided with a curved slot b into which projects a pin 19 on the arm or bracket 13. This pin serves as a stop for limiting the extent of the independent movement which the said arm 13 can perform. In the case of the fivecents drum F, which alternately registers five cents and zero, as already explained, a trans fer from this drum to the next drum of higher denominationviz., to the drum Fwould be necessary at each alternate step of the drum F. In the drawings the five-cents drum F illustrated performs six steps at each complete revolution, and therefore it is provided with three lateral pins 70 at a distance apart of two steps. At each alternate operation of the five-cents key-lever A one of the pins It acts upon the inner end K of the aforesaid lever K, which thus shifts the sliding shaft -J outwardly into a position to bring its campiece j in the path of the aforesaid pin a on the rocking frame A Then at the nextsucceeding operation of the five-cents key-lever A the said shaft J will be rocked by the said pin a striking the cam-piece 1' and will thereby shift the movable arm 13 (through the intervention of the crank j and the pin 19 a sufficient distance to cause the drum F of higher denomination to turn one step and add to its record ten cents transferred from the drum F.

K is a spring which acts to return the aforesaid lever K and the shaft J to their normal position after each displacement by the pins 70 and b is a, spring for returning the arm 1 B to its normal position. The end K of lever K is provided with. a cam-piece or incline K, (represented best in Fig. 15,) which lies in the path of the pins k so that as the drum F moves in the direction of the arrow shown in Fig. 16 they one by one come against the inclined portion K of the lever and shiftthe end adjacent to the drum outwardly, the said lever K at this time turning on the pivot. 7c.

In the case of transferring the records of the drum F to the drum F the lever K for sliding the shaft J on the main rocking bar of the dollars series of key-levers A is for sake of convenience in construction situated at some distance from the drum F. Therefore it has been necessaryto provide a de- Vice between said drum and said lever K for indicated a spindle Ii, having at its end adcents has to he recorded by this drum.

jacent to the drum I a finger l, which lies in the path of the said pin 10 of-this drum. At the opposite end of said spindle L is a pin Z,

engaging with the slotted end of the aforesaid lever K, so thateach time said barL is actuated it imparts movement to the lever K, t

which in turn imparts sliding movement to the shaft J, and thereby brings its cam-piece 7' into position to be acted uponby the projection a of'the rocking frame A The aforesaid additional rocking bars C are each provided with a stop-piece O, which lies directly behind the arm-B of the rocking bar B, so that when any of the key-levers of the series A A are depressed the said arms on f the additional rocking bars will be caused to approach the arms B on the main rocking bars.

As alreadystated, the rocking bars 0 are provided with cam-plates which'are arranged in the reverse order of that in which those on the bars B are arranged, so that'although both the bars B and 0 rock simultaneously in opposite directions the extent of movement of the bars 0 is greatest when that of the bars B is least, and vice versa. By these means I am able to vary the position of the stop-piece O relatively to the arms B so that said stop-pieces will assume a position each time a key-lever of the series A or A is actuated to insure that the arms B cannot shift beyond the distance ne'cessaryto cause the drums F F to correctly'register the amount represented by the key-lever depressed. This prevents any liability of the registeringdrums from being turned beyond their proper distance no matter how suddenly or forcibly a key-lever is depressed.

To prevent the arms I? from shifting beyond their proper ambit of movement when they are operated independently of the main rocking bar, as aforesaid, I arrange immediately at the rear of the upper ends of said arms 13 a hinged stop-piece M, which is maintained in this position by a spring m, the distance between said hinged stop-piece and the said arm 13 being only su'flicient to enable the latter to perform its proper transfer-stroke. The said hinged stop-piece is provided with an inclined on cam surface 'm for a pin e on the stop-piece C of the additional rocking bar 0 to act upon as said stop-piece C advances toward the arms 13. The hinged stop-piece M is thus raised into a position out of reach of the arm 13 when the latter is moved with the main rocking bar 13, and it therefore does not impede this movement;

In some cases a transfer from one drum to another has to be effected by the machine simultaneously with its ordinary recording operationas, for instance, when a record from the five-cents drum Fhas to be transferred to the drum F at the same timeas, say, twenty This would require the latter drum not only to be For this purpose I have turned two steps for registering the twenty cents, but also another step to register the ten cents transferred from the drum I In this case the bars 13 .and 0 would be rockedby their cam-plates, as already stated, and impart to the drum F the necessary movement for registering twenty cents. At the same time the arm 13 would be rocked independently byt-he-shaft J as the latter was actuated by the pin 0. operating on the campiece An augmented movement would therefore be given to the said drum F for adding to its record the extra ten cents transferred from the drum'F. The removalof the plate b 'from between the arms B and 0 permits of the extra amount of movement of the arm 13 the thicknessof said plate beingjust sufficient to leave a space between said arms B and C wide enough for this movement, and no more. The said arm 0 thus still serves as a stop-piece '(even when the transferring is being effected) to prevent movement beyond that which is necessary for effeet-ing the proper record.

In view of the fact that the shaft J of the series of key-levers A is in the exampleillustrated situated in an elevated position and that therefore the pin or on the rocking frame A cannot actuate the finger or cam piecej? thereon until the said frame A reaches its uppermost position it is necessaryto'provid'e means whereby the return of this shaft J to its original position by the action of the spr ng will not take place immediately the lever L I V has been actuated by the pin k but will be retarded until after the said shaft has been rocked by the said pin a and cam-piece to effect the transferring operation. purpose I provide the said shaft with a notch J Fig. 20, with which a spring-controlled arm J engages eachtime the said sliding rod is shifted into its outward position. This 1'0 For this IIO spring-con trolled arm is provided with atail f piece J against which the transverse bar A of the aforesaid frame A strikes when it as sumes its lowermostpositiou, and the eby causes the arm J to become disengaged from the notch in the shaft J.

1 15 The said shaft being thus released returns to its normal position after having been actuated by the said pin a and cam-piecej It will be obvious, however, that no such device for retarding the return movement of the sliding shaftwill be necessary when the construction ofrthe machine permits the campiece 9 to be arranged in a position relatively to the pin a similar to that occupied by the campiece 9 and pin a of the device for transferring the records from the drum F to the drum F.

The drums F and F maybe operated from the drum F in any convenient and ordinary manner, such means forming no part of my present invention. t.
