SPECIFICATION forming part of Letters Patent No. 442,851, dated December 16, 1890. Application filed April 28, 1890. Serial No. 34:9,829r No model.)

To all whom it may concern:

Beitknown that I, ISRAELDONALD BOYER, a citizen of the United States, residing at Dayton, Montgomery county, Ohio, have invented certain new and useful Improvements in Cash- Registers, of which the following is a specification.

My invention relates to that class of registers commonly employed for indicating and recording the various sums received for the sales of different articles; and my invention consists in certain improvements in such registers and the parts thereof fully set forth hereinafter, and illustrated in the accompan ying drawings, in -wl1ich Figure 1 is a front elevation of a register embodying my improvements. 2 is a plan view. Fig. 3 is a transverse sectional elevation. Fig. 4 1s an elevation of the tablets. Fig. 5 is a plan showing the arrangement of tablets in one set. Fig. 6 is an enlarged part-sectional elevation of the counter mechanism. Fig. 7 is apart-sectional plan of the mechanism shown in Fig. 6. Figs. 8 and 9 are reverse views of one of the counter-Wheels. Fig. 10 is a part section onthe line 10 10, Fig. 0. Fig. 1-1 is a reduced front view of the counter-frame, showing one set of levers. Fig. 12 is a reverse elevation of the counter-frame and parts supported thereby. Fig. 13 is a front View of one of the controllers. Fig. 14: is a detached view showing the friction-band in section. Fig. 15 is a side view of part of the pusher mechanism for operating the pins of the register-wheels.

The case A of the apparatus is constructed of suitable shape to inclose the parts hereinafter described, and is provided with a moneyrec'eptacle-as, for instance, asliding drawer B-or with a receptacle Y, provided with a movable lid or cover, and has a number of sight-openings so at the frontor back, or both, as may be desired, for the exhibition of the figures upon the tablets G.

The mechanism of the register is supported upon a platform 1. which is above the base 2 of the case, leaving the interposed space Y, and the working parts hereinafter referred to are supported by a suitable frame resting upon or secured to the platform 1.

There are three banks of keys D D D each bank having nine keys, preferably arranged -as best shown in Figs. 2 and 3. A key-lever at is connected with or forms part of each key, all of the key-levers vibrating 5 5 on a transverse pivot 5, and the rear end of each lever extends beneath or is connected to operate a staff 6, attached to an upright plate constituting a tablet 7, upon which is painted or otherwise indicated a n umbercor- 6 o responding to that upon the operating-key. As shown, the tablets are arranged in threesets connected with the three banks of keys. The front tablet of each set is marked with the figure 9,-the next with the figure S, and

so on, the last having the figure 1, and back of each set of tablets, so as to be exposed when all are down, is a fixed tablet 7, on which is the character 0.

As shown in the drawin s the re ister is o arranged for the tablets to be read from the front.

\Yith each set of tablets is combined a de- I tent S, of any suitable form; but, as shown, it

is in the form of a pawl pivoted to the frame with its end opposite the edges of all of the tablets of a series, each detent connected with the others, and ineach tablet is a notch having a shoulder g, into which notch the end of the pawl projects when all the tablets are down, and below the shoulder g is another shoulder 10, which is set in back of the line of the straight edge of the tablet, the latter being inclined at 12. Between the shoulder and the meeting-point of the straight edge of be in the position shown at the right in Fig. 0

4., supporting the tablet S, and the tablet 9 be raised the pawl will be thrown out by the shoulder g of the rising tablet 9. The tablet- 8 will then drop, and the tablet 9 will continue its upward movement until the shoulder 10 is some little above the end of the pawl. When the key is released, the tablet 9 will. drop back until the shoulder 10 on the tablet 9 comes to rest on the end of the pawl.

The use of the shoulder 13 may be explained by another operation. Suppose the tablets indicate $1.99 and the next sale to be registered is nine cents. The action is as follows: Vhen the nine-cent key is pressed, its

tablet, being already up, cannot drop the dollar and dime tablets in the way heretofore explained, because their shoulders g are already above the edges of the pawls and of course cannot push the pawls out. In this case, when the nine-cent key nears the top of its stroke, it strikes the start of its tablet and lifts it a short distancefar enough for the shoulder 13 to strike the pawl and throw it out. This will let the other tablets drop. By setting the shoulder back of the edge-line of the tablet I insure the release of such tablets as have been elevated, even if there should be slight variations in the width or lateral positions of the tablets. If more than one tablet is to be exposed at once, all must be raised at the same time, or at least if one key is pressed first it must be held down until the others have been pressed.

As there are three banks of keys, there are three sets of tablets and three detents, and I provide the shaft or end of each detent with an arm 7 O and connect all the arms by a rod 71 or otherwise, so that all will move together. This insures the dropping of all the tablets when a key is depressed, (or when several keys are depressed together,) so that before a new number can be set up that previously indicated will be obliterated. This prevents fraud, for otherwise by altering a single number and recording a small sum a larger nu mber mightbe indicated. Thus if asale of one dollar and twenty-five cents has been made and the register shows that sum, and if the next purchase amounts to one dollar and seventy-five cents, the salesman by striking the 7 key of the second bank can cause the register to indicate $1.75, while registering only seventy cents additional. If all the de tents were connected together, the attempt to substitute 7 for 2 in the second bank would drop all the tablets, and a new display and corresponding registration would have to be made. By connecting the detents togetherl avoid the necessity of using ten keys in each bank and the necessity of operating three keys for each sale. Thus with independent detcnts to register seven cents it would be necessary to move the keys to show ciphers or 0 in the banks D D and register 7 in the bank I). To register ninety cents it would be necessary to move the keys to show 0 on the tablets in connection with the banks D D and register 9 in bank D. By using fixed zero-tablets it is only necessary to drop the other tablets to expose the O, and even with this arrangement if the detents were independent it would be necessary to operate three keys at each registration in order to drop the tablets indicating the number previously registered.

Asit is necessary, in order to insure the effective operation of the tablets, that each key-lever shall move to its full extent at each operation,I combine controllers with the keylevers, one controller E to each bank or set of keys, and constructed in any suitable manner and Supported to yield to permit each key-lever to be depressed at the forward end, but preventing any return movement until the first movement is completed to its full extent. As shown, the controller of each bank consists of a connected series of pendent racks 14, Figs. 3 and 13, all secured to a cross-plate 15, having cars 16, hung upon pivots 17, so that normally the racks swing toward lips 18 upon the sides of the key-levers, and when any lever is lifted its lip will engage with the shoulder of the rack, which will prevent its descent, but not its ascent. \Vhen, however, the rear end of a key-lever is lifted to its full extent, as shown in dottedlines in Fig. 3, it strikes the cross bearing-plate and swings the controlleroutward elearof the path of the projecting finger or lip 18 until the end of one of the racks passes the point or end of a retainerin the form of a COUIltOl'WGlglillQtl pawl 20, hung upon the pivot 5, when said pawl rises and holds the controller in the position shown in the dotted lines,l' ig. 3, so that the key can resume its normal position. The full elevation of each tablet after the movement of the key has begun is thus insured. It will be evident that the controller may be otherwise than pivotally supported to yield on the upward movements of the keys. As thekey approaches its normal position, the pawl 20 is thrown down by the contact of a frame F, described hereinafter, and the controller is released,assuming the position shown in full lines, Fig. 3.

The drawer (or the door or cover of the receptacle Y when a drawer is not used) is socured by a single bolt, so that it can only be opened. upon the depressing of one of the keys. In the construction shown, in which a drawer is used, the latter has a shoulder 21, in front of which a bolt 22 drops when the drawer is at the limit of .its rear movement, said bolt being in the form of a lever extending through a slot in the platform 1 and pivoted at the forward end to a plate 23. In connection with the bolt there is a pivoted catch 24, hung to an ear upon the plate 23, and with a lip 25, which, when the bolt is elevated, catches beneath a shoulder 26 thereof and maintains it in its elevated position. The belt 22 is connected by a link 27 with the frame F, hung at the rear to a pivot 28, and carrying two cross-bars 29 and ill.) at the front, the former resting upon the upper edges of all of the key-levers and the latter occupying a more elevated position, and when a key is depressed the frame F is raised until a pin 73 thereof reaches the end of a slot 7-t in the link .7 and lifts the bolt 22 until the catch 2t swings inward, engages the shoulder 26, and holds the bolt in its elevated position. when the drawer is released. As shown, the length of the slot 7-.t is preferably such that the bolt will not bewithdrawn until the key depressed approaches or reaches the limit of its movement. At the back of the drawer is pi voted a spring contact-piece 3.1, which yields when the drawer is drawn forward, but when the drawer is pushed back the contact-piece passes the bolt 22 at one side and strikes a finger 32 of the catch 24, swings the latter back, and releases the bolt, which then falls opposite the notch 21 and locks the drawer. Vhen the catch 24 is pushed back, it is temporarily held in this position by the endof a detent in the form of a small catch-spring 33, which flies up in front of a lug 34, but which is depressed, so as to release the catch, by the contact of a lug 35 on the bolt as the latter descends to its full extent.

It will be evident that other connections than those described may be used between the key-levers and bolt 22 to move the latter when a key is depressed.

The device as above described may be used in connection with any of the ordinary or suitable counting mechanisms; butl have devised a special construction of counter adaptedfor use in connection with such devices or with other devices, and which I will now describe. The said counter mechanism is arranged within a frame or case G, contained within the main case A and above. the keylevers, the maincase having a series of openings y, through which the figures upon the movable portions of the counter can be seen.

Before describing in detail the construction of myimproved counting mechanism I will refer to those of the ordinary construction and to difficulties incident to their use, which difficulties it is my object to overcome.

Total-adding cash-registers have generally either positively-actuated counters, in which the keys directly move the counting mechanism, or they are provided with counters operated at proper intervals by weights or springs. Cash-registers are subj eoted, as a general rule, to rough usage by clerks and attendants who are opposed to their use and do their utmost to damage them, and it therefore follows that. registers of the firstmentioned class must be made very strong and heavy to prevent damage from the rough blows given to the keys which impart momentum to the registering devices, and this also renders it difiicultto arrest the counting mechanism at the proper point. Efforts have been made to overcome such momentum by means of a -heavy brake or the resistance of springs to the blows of the keys; but where the results are effective there is too much resistance to permit the keys to be operated with the desired facility. Dash-pots of different kinds have been used to overcome momentum from rough usage; but these necessitate slow movements which are annoying to the operator. Further efforts to obviate this difficulty have consisted in the use of mechanical stops thrown into engagement with the countingwheels as the keys complete their stroke. The results .in such case are not satisfactory,

as a rapid initial movement of the key will throw the counting-wheel beyond its proper position. In otherinstances the initial move- .or otherwise.

ment of the key has been made 'to lock the counting. mechanism fast, and when all parts are locked together the registering is effected. In such case the mechanism required is quite complicated, and the results thus far obtained have not been satisfactory.

In that class of registers in which the counters, instead of being moved directly by the keys, are operated by weights or springs the parts receive no objectionable impetus from the keys themselves; but if the weights or springs are heavy the momentum of the parts results in imperfect registration,-while if they are light the mechanism is too delicate for practical use. In registering amounts which require a movement of nine or more notches even a light spring will produce a high velocity, and when the spring is made so light that its maximum velocity is not great then it is likely to be deficient in power in registering low amounts. As a general thing the regulating mechanism of the counters has been separate from the counting-train, so that'the difficulties incident to stopping the countingtrain have been experienced in all of this class of devices.

In another class of machines the regulating mechanism forms a part of the counting-train, the wheels of which work between escapements, permitting a definite part of a revolution at each movement of the key, so that it is impossible for the train to acquire movement in advance of the regulating mechanism. Such devices, however, can only be employed in connection with complicated mechanism not practically applicable to machines where less than five cents must be registered at one time.

My improved counting mechanism, which I will now describe, effectuallyovercomes the difficulties of the various plans above referred to, so that in a machine having four banks of keys any amount from one cent to ninetynine dollars and ninety-nine cents may be positively registered at one operation, the entire key-board being within easy reach of the fingers of the two hands. In said improved mechanism (best illustrated in Figs. 6 to 11) there is a counting-train consisting of a series of wheels or disks I, six being shown, each mounted upon a horizontal shaft 40 and all of the wheels being in line with each other, one beneath each of the series of openings y in. the outer case. Each wheel has two series of digits, from O to 9, upon its periphery, and in connection with each wheel there is a motor, which may be in the form of a spring, weight, or piston operated by compressed air As shown, the motor of each wheel is a weight W, which is pendent from a sector 41, pivoted to the frame and having rack-teeth engaging those of a clutch-pinion 42, which turns the shaft with it as the weight descends, but which turns'on the shaft when upon the shaft l0 and preventing the latter from turning back when the weight and sector are raised. The bar 30 of the frame F extends under all of the weights, and as this bar is raised on depressing any key the maximum power is stored in the motors at each movement of each key, so that the power of each motor is always available to turn the counterwheel I whenever the latter is released by the action of a key or keys.

In order that each wheel may be turned to an extent to record the number indicated by the key that operates it without any direct connection between the wheel and the key and without possibility of the wheel being thrown beyond the proper point by momentum, and in order that each wheel may be locked until the key has performed its operation, I combine with each of the wheels operated from each of the banks of keys a bolt and a series of movable pins constituting, with the parts hereinafter described, a releasing or escape device, the pins being car ried by the wheel or another disk, so as to turn with the wheels. I carries twenty pins a, one to each of the numbers upon the periphery, all arranged in a circle and parallel to the shaft. In the three left-hand wheels these pins are fixed, projecting beyond the front faces of the wheels; but in the three right-hand wheels they are free to slide longitudinally with sufficient friction to retain them in any position in which they are placed. This friction is secured in any suitable manner. In the construction shown it is effected by means of a flat spring-ring 75, with an inner rubber facing encircling the series of pins and bearing upon all, as shown in Figs. 7, 9, and M. Adjacent to the right-hand or cents wheel is secured a fixed stop I), which projects into the path of the pins projecting from the front face of the wheel, and the latter can only be turned by the motor after one or more of the pins is pushed back, when the wheel will be turned as many steps or parts of a revolution as corresponds to the number of pins pushed back. The pins are pushed back by the action of the bank of keys connected with the wheel and are operated through the medium of any suitable intermediate devices so arranged that when the key marked 1 is depressed the pin next adjacent to the stop I) will be pushed back, allowing the wheel to turn one step, exhibiting the figure 1 opposite the opening 1 but if a higher key, as (3, is depressed six pins will be pushed back and the wheel will move six steps and exhibit the figure G opposite the opening. One construction of connections whereby this result is effected is illustrated in the drawings. In the front plate 1% of the countercasing opposite each wheel and in a half-circle concentric with the shaft of the wheel is a series of openings 145, through each of which extends a pusher, (shown in the form of a As shown, each wheel rod 4.6,) each connected to 01' forming part of a lever 47, the rods being so arranged upon the lovers as to be immediately opposite said openings and bent to conform to the circular arrangement thereof, as best shown in Fig. 15. To the lower end of each lever at? is connected a rod 48, which passes through an opening 50 in a cross-bar elf) of the frame to a position opposite a shoulder 51 upon one of the key-levers, the parts being so arranged that when a key is depressed the shoulder 51 will force outward the rod l8, vibrate the le ver 47, thrust in the rod 46, and the latter will strike the end of one of the pins to and push it back out of the path of the projection I). hen the key-lever assumes its normal position, a spring 151 throws out the lever 47 and the rods 46. Each of the levers 47 or of the key-levers or other adjacent parts has a lip 53, Figs. 6 and 10, that overlaps the lip of the adjacent levers or parts of lower denomination, so that when any key is depressed and the lever connected with said key is vibrated all the levers connected with the keys below that vibrated will move with it, while the levers connected with the keys having numbers above that which is being depressed remain stationary. Thus if the key 6 is depressed the levers connected with the keys 7 8 9 will remain stationary,while all the other levers connected with the keys 6 5 t 5 2 I will be vibrated, the corresponding six pins CL will be pushed in, and the motor will move the wheel six steps. If desired, the ends of the levers 47 might make direct contact with the shoulders 51.

The counter-wheel is preferably locked as soon as any key begins its movement by means of any suitable locking-bolt-as, for instance, a bolt 0, carried by a sliding frame J and adapted to a series, of openings w in the back face of the wheel, Fig. 9, the frame being moved forward by intermediate connections with the key as soon as the latter is depressed. Thus the frame J is connected with a crank-lever 55, Figs. 3 and 12, which is also connected with the frame F, and is vibrated when the frame F is raised by depressing a key, so as to push forward the frame J and thrust the bolt 0, Fig. 7, into the opposite opening in, Fig. 9, of the counterwheel. When the key-lever and frame F as sume their normal positions, the frame J and the bolt are drawn out, and the wheel I can turn a number of steps, corresponding to the number of pins (L which have been pushed inward. preferable to lock the counter-wheel while the devices that regulate its movement are being set into position and to restrain the action of the motor until this is effected.

At the forward end of the frame J is a segmental plate 56, which, when the frame moves forward, makes con tact with the inner ends of any of the pins a that were previously pushed back and thrusts them forward, the segment ICC The bolt 0 is not essential; but it is being so arranged as to operate only upon the pins of the upper section of the wheel that have passed the step b.

Other means of shifting the pins back to position might be employed-as, forinstance, an inclined bearing over which the pins travel after they pass the stop. The pins a. may be carried to turn with the counterwheel, but upon another wheel or disk instead of on the counter-wheel.

In order to carry decimally from one wheel to the other, so as to accumulate the totals upon the higher wheels, I place between each wheel and that above it a suitable transfer device K, constituting atemporary stop for the higher wheel. As shown, the transfer device consists of a shaft 76, provided with an arm 57, in position to be struck by two blades or pins 58 58 upon the next lower wheel (one to each series of numbers) and with a stop or escapement arm 59, having a stop-lug at the outer end with an inclined slot 60in such position as to be entered by the pins of the next upper Wheel when the shaft is rocked to one position by the contact of the pin 58 with the arm 57 of the lower wheel. Normally the parts are in the position shown at the right.- in Fig. 6, one of the pins bearing against the lug of the arm 59, which holds the wheel in position. As soon, however, as the lower wheel has completed a semi-revolution (completing the highest record and requiring the transfer of 1 to the next wheel) the pin 58 rocks the shaft 76 by contact with the arm 57, and the slot 60 in the arm 59 is brought with its outer open end in the path of the next pin of the higher wheel, when such pin is free to enter the slot and the wheel will be moved by its motor one step, acting as an escapement, the passage of the pin through the angular slot 60 swinging the arm 59,slightly until the lug thereon is in the path of and will make contact with the next pin, arresting the further movement of the wheel. The higher wheel is thus automatically advanced one step at each operation of the transfer device. automatic transfer or carrying from one wheel to the next higher wheel will not only result when the lower wheel is actuated, but will also take place if the keys in both the banks are operated at the same time. This results from the fact that whatever may be the number of pins of the higher wheel pushed back by the action of its key the transfer device willbe in such a position that the pin of the higher wheel next to the last pin pushed back will enter the slot 60 and automatically advance one step,but in so advancing will set the arm 50 back to prevent the next pin from'entering the slot. The escapement or transfer lever has such a frictional bearing that it will remain where left, but can be readily shifted.

Each of the three right-hand wheels is operated from one of the three banks of keys;

but the three left-hand wheels are actuated This only by the transfer devices, and, owing to the absence of the levers 47,these upper wheels may be placed in closer proximity than the lower ones.

To set the train to zero the proper key of the cent-bank is first operated to bring the centwheel to zero and then the key of the dimebank, and then the key of the dollar-bank, and then each one of the succeeding wheels may be set to zero by vibrating the transfer device step by step. This may be done without difficulty be means of an arm 62, extend ing from the shaft 76 of the transfer device through the top of the case.

The apparatus is provided with a gong SO and with a striker 81,pivoted to any suitable portion of the frame. As shown in Fig. 12, both are mounted at the back of the counterframe, a spring 82 carrying the striker toward the gong, and a lever 83, connected by a rod 8t with the frame F or any other moving portion of the machine, carries a loose pawl 85, which makes contact with the end of the striker-arm and retracts the latter as the lever 83 is raised, but passes loosely over the end of the arm when the lever 83 is depressed.

The key-levers may carry the keys directly upon their ends, and thus constitute the keys themselves, and they may be weighted at the inner ends, so as to insure their automatic return to their normal position.

By arranging the levers 47 in sets each inclined, as shown in Figs. 6 and 11, I am enabled to increase their length and at the same time bring the counting mechanism close to the key-levers,thereby rendering the machine 111016 compact.

The levers 47 might be connected with the keys in other ways than shown; but by providing the counter mechanism with operating devices in position to be actuated by contact with shoulders of the key-levers I am enabled at any time to separate the counting mechanism from the keys without the necessity of loosening a series of separate connections. In the constructions shown the counter may be removed by simply disconnecting the pin 90. v

It will be evident that many of the devices above described may be'used in connection with machines of different constructions.
