Application filed January 9, 1891. Serial No. 377,244. (No model.)

To all whom t may concern.-

Be it known that I, JAMES JACQUES, a subject of Victoria, Queen of the United Kingdom of Great Britain and Ireland, residing at Chelmsford, in the county of Middlesex and Commonwealth of Massachusetts, have invented a certain new and useful Improvement in Cash Registers and Indicators, of which the following is a specification.

Myinvention relates to cash registers and indicators; and it consists in the devices and combinations hereinafter described and claimed, the same comprising devices for preventing' the simultaneous depression of two or more keys; devices for printing tickets to indicate the amount of purchases and for severing such tickets from a roll of paper; alarm, indicating, registering', and signaling' devices; devices which require the movement of any key to be completed in one direction before such key can be moved in the other direction, and drawer locking and unlocking mechanism.

In the accompanying drawings, on four sheets, Eigure l is a vertical section from front to back of the machine on the line l l in Eig. 2; Eig. 2, a horizontal section of part of the machine on theline 2 2 in Fig. l, parts of the case in front and at the right of the machine being broken away; Fig. 3, a vertical transverse section on the line 3 3 in Fig. 1, parts of the case, drawer, and mechanism being broken out to save Space; Eig. 4, a right side elevation of one of the rack-rods, its locking and releasing mechanism, and a part of the drawer-unlocking mechanism and a vertical section of a part of the drawer; Fig. 5, a vertical section on the line 5 5 in Eig 4, of a part of the case and of a rack-rod and its locking mechanism and a front elevation ofthe unlatching-rod and its operating-linger; Eig. 6, a horizontal section of a part of the case and a plan of a rack-rod, the unlatching-rod, its operating-linger, and a part of the rockshaft and the arm of said rock-shaft to which said unlatching-rod is connected; Eig. 7, a section on th'e line 7 7, in Fig. 4, of apart of the case, a rack-rod, one of the pawls which engages the same, and the lever which throws one ot said pawls into such engagement when the other of said pawls is thrown out of such engagement; Fig. S, a plan of the rear left corner of the drawer, a part of the signalunlocking lever and its operating-incline, and a part of the alarm devices; Fig. 9, a right side elevation of a part of the frame, the registering-wheels, the registering-pawl, and transferring-pawl, the weighted transferringlever, and a part of the paper-reel; Eig. l0, a left side elevation of a part of the frame, the signal-unlocking lever pivoted thereon, and an end elevation of the locking-rod, a signal, part of its rod, and a part of the paper-reel; Eig. ll, a left side elevation of a transferringlever and registering-wheel; Fig. l2, asection of stop-rods and part of the case on the line 12 l2 in Eig. l, and a front elevation of some stops and their supporting-rod; Fig. 13, a rear elevation of a type-lever, Eig. 14, an isometric perspective view of the units and tens registering-wheels and their operating mechanism; Eig-.15, an isometric perspective view of the transferring` pawl-lever and its pawl; Eig. 1G, a front elevation of the registeringwheels and their operating mechanism, the large gears which drive the loose pinions being partly broken away.

The case A, the upper portion a, containing registering, indicating', signaling, and printingmechanism, and the drawer B, sliding in the lower portion a of said case and forced outward by a leaf-spring I), secured to the inside of the case behind the drawer, are of the usual construction and operation.

The frame C is arranged within the portion a of the case A and supports the different mechanisms. The keys D are bent levers which turn loosely upon a com mon fulcrumrod d, supported in said f rame, the front arms d of said keys extending through slots a2 in the case and terminating in numbered buttons cl2 in the usual manuel'. The rearlower arm (Z3 of each key is forked, as shown at rl, to engage a laterally-projecting stud e on a horizontally-sliding stop-rod E, there being a separato stop-rod for each key, so that a depression of any key pushes the corresponding stop-rod longitudinally backward.

At each side of the machine is arranged a weighted lever F, pivoted upon a rodf, supported at its ends in the frame of the machine. The front ends of the weighted levers E are pivoted at f to the rear ends of other levers E', the front ends of said last-named levers being connected to each other by a rod f2, which extends over all the stop-rods G of all the keysjust in front of the lower ends of the keys, as shown in Fig. 1, so that when a key is depressed it raises the weights F2 of the toggle-levers F F', and when said key is released the falling of said weights tends to straighten out said levers or cause them to approach the same straight line, throwing the rod f2 forward and restoring the key and stop-rod to their normal position. Each stoprod E is provided with a downward projection e', which when the corresponding key is depressed is pushed backward between two adjacent stops G, each of said stops consisting of a disk shaped like two frustums of cones arranged concentrically base to base. The stops G are centrally perforated and hung upon a rod C, which extends under all the stop-rods and is supported in the frame, as shown in Fig. l2, said stops beingadapted to slide on said rod laterally in such a manner that there is space enough for a single projection e' between two adjacent stops when said stops are as far apart as possible, and all the stops on each side of said projection are in contact with each other.

The stops G are arranged immediately behind the projections e' and in close proximity thereto, so that when any stop-rod has moved far enough to carry its projection c' between two adjacent stops no other stop-rod can be moved backward, so that no two stop-rods can be simultaneously moved, and therefore no two keys can be simultaneously depressed.

The signals H each consist of a tablet of thin material, as sheet-metal, bearing the same number as the key which operates it and secured to the upper end of the vertical signal-rod ZL, which slides in horizontal guides c c', which extend from side to side of the frame in the usual man-ner. Each stop-rod is provided with a` laterally-projecting pin e2, which presses against the lower arm of a bellcrank lever l in such a manner that the other arm of said bell-crank lever, which extends under the lower end of the corresponding signal-rod h, is raised and raises said signalrod and the signal carried thereby at every depression of the corresponding key, so that the number of said signal is displayed at windows CL3 CL4, with which th'e case is provided in the usual manner. Each signal-rod is provided with an incline h' and passes through a hole in a locking-rod J, which is supported horizontally in the frame of the machine below the upper guide c, and is provided with slots j, (see Fig. 3,) of greater width than the signal-rods, through which slots said signalrods pass. A weighted lever j is pivoted on a bracket jg, supported on the frame C in such a manner that an end of said lever bears against a shoulder jg on said locking-rod and forces a side or end of the slotj into contact with the incline h of each signal-rod h, so that when any signal-rod is raised its incline forces said locking-rod endwise against the resistance of said weighted lever j until a notch h2, formed in each signal-rod at the lower end of its incline, is raised suiciently to allow said locking-rod to be forced by the pressure of said lever j' into said notch and to retain said signal-rod in its elevated position with its corresponding signal displayed at the windows c3 0.4, above mentioned.

When the signal is once displayed at the windows, it remains in an elevated position until the drawer Bis opened. Alever J is pivoted to the frame C at cthe upper end of said lever engaging a downhanging projection 3'4 and the lower end of said lever being pushed aside by a cam or incline b', secured to the inside of the side of the drawer near the back thereof when the drawer is opened, the back of the drawer being cut away at b2 to allow said back to move forward without striking the lower end of said lever J. Vhen the drawer is drawn forward, the lower end of said lever J is swung toward the middle of the drawer and the upper end of saidv lever moves the locking-rod J against the resistance of the weighted lever j' and disengages said locking-rod from the signal-rod of a raised signal, allowing the same to fall.

A registering-lever K turns on the vertical pivot k and extends over all the keys of a bank or series, as shown in Figs. l, 2, and 3, and each stop-rod is provided with an upward projection c3, arranged in front of said registering-lever and adapted to strike said lever and swing the same backward whenever a key is depressed, said lever carrying a pawl Zc, pivoted thereon and engaging a registering-ratchet K', said pawl being weighted to keep it in engagement with said ratchet. The projections e3, which strike and move the registering-lever K, are so arranged as to operate said registering-lever to rotate said registering-ratchet an angular distance measured by the number of teeth indicated by the number on the corresponding key, the depression of the key marked l rotating said ratchet an angular distance measured by one tooth of said ratchet, and the key marked 9, when completely depressed, causing said ratchet to rotate nine times as far. Secured to the same shaft Z, with the registeringratchet K', is a gear L, having the saine number of teeth as said ratchet, each having ten teeth or a multiple of ten teeth, preferably the latter.

The gear L engages a pinion L', having ten teeth or a multiple of ten teeth and turning loosely on the shaft Z', (which also supports all the numbered registering-wheels M M' M2 M3 M2) and causes said pinion L' to make a complete revolution at every partial rotation of the registering-ratchet K' an angular distance measured by ten teeth of said registering-ratchet. (See Figs. 9, 14, and 16.) A tentoothed ratchet Z2 is (except as hereinafter stated) loose on the hub Z3 of the pinion L', concentrically therewith, but is caused to rotate therewithr in the direction shown by the IOO adjacent arrow in Fig. 9 by a pawl Zpivoted on an arm Z5, projecting from said hub Z3 and engaging a small ten-toothed ratchet Z6, secured to said ratchet Z2. To the ratchet Z2 concentrically therewith is secured a registering Wheel or drum, as M, carrying ten figures on its periphery,t`rom O to 9, inclusive.

It will be understood that there are at least as many registering wheels or drums as there are banks of keys, five such registering-wheels M M M2 M3 M'1 being represented in Fig. 3, the wheel M at the extreme right registering cents, the next M registering dimes, the wheel M2 registering dollars, the wheel M3 tens of dollars, and the wheel M4 registering hundreds of dollars. To each such registering-wheel a ratchet Z2 is secured. Each ratchet Z2 is prevented from a return movement by a spring-pawl Z2, secured to a collar ZS, fast on the horizontal rod Z9. There are as many pawl-levers N pivoted on the rod Z9 as there are registering-wheels less one, and the ratchet Z2 ot' each registering-wheel (except the registering-wheel M at the extreme right) is engaged by a pawln2, carried by such a pawl-lever. Each pawl-lever has a Weighted arm, which tends to throw the upper pawlcarrying arm of said lever forward against a stop n. (See Fig. 9.) Each registering-wheel (except the one at the extreme left of themachine) is provided with a laterally-extending finger fm, which once in every revolution of said registering-wheel strikes an incline n on thepawl-lever N next to the left of said registering-wheel and crowds said pawl-lever backward far enough to turn the corresponding ratchet Z2 an angular distance measured by one tooth of said ratchet; but in case said registering-wheel is at some distance from the registering-wheel next to the left thereof a separate lever N', just like a pawl-lever N, but not carrying a pawl, is (see Figs. ll and 14) pivoted on said rod and is connected rigidly by a rod n3 to the pawl-lever next to the left, these two in eiect forming abroad pawllever. Each registering-wheel (the centswheel M, the dim es-wheel M', the dollar-wheel M2, and wheels MS M4 to theleft of the dollarwheel) is so numbered with reference to the position of the finger m that in turning from 9 to O the next Wheel to the left is roiated one-tenth of its circumference by the hooked pawl n2being drawn backward by the above-described action of the finger m on the incline of the pawl-lever. Thus when the registering-wheel in the lowest or in the intermediate section stands at 9 and it is rotated one-tenth by the depression of the key marked l in the case of the lowest section or l0 in the case ot the intermediate section, the wheel so rotated immediately dis`- plays a O and causes the registering-wheel next to the left to display a figure one greater than the one previously displayed byit. The finger m, when its wheel makes a tenth of a revolution after bringing said iinger m in contact with said incline, passes by said incline and allows the lever carrying said incline to return to position.

The units or cents registering wheel M, or registering-wheel at the extreme right, may of course be rigidly secured to its pinion L and ratchet Z2, the parts always moving together, inasmuch as said registering-wheel M is never actuated by a registering-wheel of another denomination, said ratchet Z2 serving, with the corresponding pawl Z7, merely to prevent a backward movement of said wheel M, and the finger m may be secured to said ratchet Z2, as shown in Fig. 16.

At each side of the machine is pivoted, at 0, a lever O on the frame C, Figs. l and 4, said levers O being held parallel with each other by their pivots o, and by the said rod f2, which connects said levers rigidly to each other, so that the depression of any key throws the forked upper ends o of said levers O backward. On eachkeyD is pivoted, at CZ, a hook CZ5, the rear end (Z7 of which drops by its own weight over the rod f2 upon a depression of such key too slight to cause any movement of the registering-lever, said hook being disengaged from said rod f2 when the key has nearly returned to position, by the front end Z8 of said hook running under an incline (Z9, secured to the inside of the front of the case, (see Fig. 1,) so that a depressed key can return to position only with said rod f2 and levers O. At each side of the machine is arranged a horizontal sliding rod I), provided with a laterally-extending stud p near its front end, which enters the fork o of a lever O, causing said rod P to move with the upper endof saidleverO,theforward movement of such rod P and lever O being caused by the return of the weighted toggle-levers F F, above described, to their normal position. Each rod P is provided with a rack p on its uppersurface adapted to be engaged by pawls p2 p3, pivoted at 294195 on the case A. The pawls which engage the same rack-rod P are arranged with their free ends toward each other, and above each pawl is placed a leafspring Q Q, the shape of which is fullyshown in Figs. l, 4, and 7, secured to the case A in such a manner that either of said pawls may be raised and held by the pressure of the corresponding spring out of engagement with the rack-bar P. A lever Q2 is pivoted to the case A at each end of the machine and is provided with laterally-projecting arms q q', which extend over the pawls p2 p2 in such a manner that when either pawl is thrown upward into engagement with its spring the other pawl is thrown downward out of engagement with its spring. )Vhen the rackrod P is pushed backward, the pawlp2 engages said rack p and prevents the return of said rack-rod until the key to which the motion of the rack-rod is due is fully depressed. )Viren any key is fully depressed and the rack-rod has completed its backward movement, the pawl p2 is raised out of engagement with the IOO IIO

rack p by an incline p6, secured to said pawl, riding up over another incline p8, secured to said rack-rod. The pawl p2is thus raised sufiiciently to rock the lever Q3 and to become engaged by the spring Q, which holds said pawl p2 until the return of said rack-rod to its normal position. The rocking of the lever Q3 by the raising of the pawl-rod p2 throws the pawlp3 down into engagement with the rack p' and prevents any backward movement of said rack-rod until the forward movement of said rack-rod is completed. Just at the completion of the forward movement of the rack-rod P an incline p7, with which the pawl p3 is provided, is raised by an incline p9, secured to the rack -rod, lifting the pawl p3 high enough to be engaged by its spring Q', rocking the lever Q3, and throwing the pawl p2 again into engagement with the rack-bar. By the means above described the depression of any partially-depressed key must be completed before such key can be restored to its normal position, and its return movement must be completed before any second depression of said key is possible. (See Figs. l to 7.)

A rock-shaft R is journaled in brackets r, secured to the inside of the case A back of the drawer B, and is provided near each end with a hooked arm or latch r', which engages the back of the drawer and prevents the opening of the same, the free end of said latch r being beveled at r2 in such a manner that the drawer may be shoved back under said latch, raising the same and rocking the rod R in an obvious manner. The rock-shaft R is provided near its ends with arms r3, throughwhich pass the lower ends of the vertical unlatching-rods R', nuts r4 being turned on said rods R' below said arms 'r3 and said unlatchi-ng-rods being guided in holes r in the part of the case on which the frame C rests and in guides r6, secured to said case. rlhe upper end ot each unlatching-rod R' is bent laterally in such a manner as to be struck and raised by a pivoted iinger p10 on the rack-rod P, said nger running under the bent upper end of said unlatching-rod and lifting the same when the rack-rod is pushed backward, and said iingerbeiug offset at p11 in such a manner that when said rack-rod is pushed back to its greatest extent said offset passes said unlatching-rod and allows said unlatching-rod to fall in front of said offset. When the rack-rod P returns to position, said offset p11 rides over the top of the unlatching-rod and drops in front of said rod in position to raise said rod upon the subsequent depression of any key. (See Figs. l to 6.)

Each registering-lever K is restored to position after the depression of the key by weighted toggle-levers K2 K3, similar to the levers F F', the rear end of the weighted levers K3 being pivoted on the same rod f on which the rear ends of the weighted levers F are pivoted, said levers K2 K3 being pivoted to each other at their adjacent ends, at 7a2, and the front end of the lever K2 being notched at k2 (see Fig.

'returns to its normal position. reel is prevented from a backward movement l) to receive said registering-lever near the front end of said registering-lever, which is also notched at h4 (see Fig. 2) to receive the front end of said lever K2 and to prevent a lateral movement of the same on saidregistering-lever.

On the rod f are supported as many paperreels S as there are keys, each reel carrying a strip of paper s, (see Fig. 1,) and being provided with a ratchet the teeth of which are represented as laterally-projecting pins s', arranged at equal intervals from each other and at equal distances from said rod f, and therefore at equal distances from the center of said reel, adapted to be engaged by a spring-pawl s2, such a pawl being secured on each stop-rod E and having a beveled free end 33 adapted to slide under and past one of said pins s' when said stop-bar is pushed backward and to engage one of said pins and torotate said paper-reel when said stop-bar Each paperthe outline of a figure, as shown at S7 in Fig.4

13, said type-levers being so arranged as to be struck by the backward movement of the stop-rods E, and the figure on each type-lever agreeing with the figure on the key which actuates it, so that when any key is depressed the type-lever is thrown back against the paper s, which hangs from the corresponding paper-reel S and prints upon said paper aflgure corresponding with the iigure on the depressed key. The type-lever also carries at its upper edge a knife s, which cuts o apiece from the lower end of the strip of paper so marked or printed and allows theprinted ticket thus made to fall into a pocket a5, arranged in the lower part o.' of the case A in the rear of the drawer B, and closed by a door a7, provided with a lock as, of which only the proprietor or cashier or other trusted person has the key. A window a6 at the back of the case A allows the reelsk S to be inspected and the amount of paper on each to be approximately known in order that said reels may be at all times properly supplied with paper.

The alarm devices (see Figs. l and 8) consist of a bell or gong T, suitably supported on the inside of the case A, a bell-lever t, pivoted at t' on said case and having a slightly elastic upper arm, and a hammer t3, secured to its upper end and forced by a spring t4, which presses upon the lower arm of said bell-lever, into close proximity with said gong, the lower end of said bell-lever having a lateral projection t5, as shown in Fig. 8, which extends over the drawer B, said drawer being cut away at b2 at the side of the drawer to admit said projection and another spring t2 being secured to the top of said drawer and extendingoverthe cut bin such a manner that lOO IIO

when th lateral projection on said bell-lever runs under said last-named spring, lifting the same, and passing by the free front end thereof, so that when the drawer is again opened said spring t2 runs under said lateral projection, turning said bell-lever upon its fulcrum and carrying the hammer away from the gong until said spring t2 passes the projection t5 and allows the bell-lever to be restored to position by the action of the spring t4, the momentum of the bell-hainmercarryin (r it against the gong T. n L
