CASH-REGISTER.

Patented Nov. 14, i911.

Application filed November 8, 1907. Serial No. 401,284.

To whom it may concern:

Be it known that I, VVILLIAM H. MUZZY, a

citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Cash-Registers, of which I declare the following to be a;

full, clear, and'exact description.

This invention relates to improvements in cash reglsters ple counter registers.

The principal object of the invention is to 1 provide an improved mechanism including; an unlimited number of detachable registering mechanisms which may be used to keep 3 separately the receipts of different clerks,

' Wlll then be lowered and moved forward n departn'lents or customers accounts.

Another object of this invention is to provide automatically operating locking devices for the movable elements of the registering} mechanism when the latter is detached from the machine, so as to prevent manipulation of said elements. I

With these and incidental objects in view,

the invention consists in certain novel feaspecifically described with reference to the drawings which accompany and form part v a an index formed uponthe cabinet of the machine (not shown). Each one 'of'these side elevation of the machine embodying my invention showing the operating gearing Fig. 2 represents a central transverse section through the machine. Fig. 3 represents a top plan View of one of the detachable counters with the top of its casing removed. Fig. 4 represents a transverse section through the same showing the locking pawls for the counter wheels and the transfer devices. Fig. 5 represents a detail side elevation of the last counter wheel for each counter with the locking mechanism therefor. Fig. 6 represents a rear elevation of the machine, and Fig. 7 represents a detail perspective view of a pair of rack bars for actuatin the main registering mechanism and the indicators. Fig. 8 represents a top plan view of a detachable counter in its casing, and Fig; 9

represents a detail perspective view of one and more particularly to the; type of machine known in the art as multla connected to the levers will be afterwarderal as comprising a vers for controllingthe amountsto be added upon the main registering mechanism as well as upon a detachable counter and also for controlling the indicators for display to be added has been set up by the levers, the main counter ismoved across racks con- 1 nected to the levers and the amount represented by the positionof the levers will be added thereon. Auxiliary rack bars also cammed forward successively to register u on the detachable counter which has previously been brought rearward and elevated into engagement with said rack bars. The carriage carrying 'the detachable counter which position the counter may beremoved. Having described in general terms the operation of the invention a detail description of the different parts will now be given. As a number of parts shown in the present drawings are old and well known in the art and are shown in the patent to Carroll 751,611-February 9, 1904, I willrefer to said patent for such description as is not here given.

Amount determining deo'z'ces .-These devices comprisea series of adjustable levers Each lever is arranged to be moved a ong levers carries a segmental rack plate 2 mounted upon a transverse shaft 3', while at its outer end it is provided with a knob 4. Each plate 2 meshes with a vertical rack bar or actuator 5 and'a horizontal rack bar or actuator 6, from which it will be seen that any movement of thelever 1 will be conveyed to said actuators.

Registering mechanism.-This machine is provided with a movable carriage upon which may be placed any one of a plurality of detachable counters, after which the carriage is moved rearwardly and upwardly carrying the counter into the path of the horizontal racks. The racksare then moved forward to effect the registration. A total counter upon which is entered the difi'erent amounts registered upon the detachable counters is also employed and is reciprocated "upon each operation of the machine, during which movement the vertical racks prev series of adjustable leing the amount added: After the amount 1, only one "of which is shown, see Fi 2.

ously described actuate the counter, all of which is described in the aforesaid patent to Carroll. Each of the detachable counters is provided with a series of movable elements 7 in the form of adding wheels to which are attached gear wheels 8 rotatably mounted upon a transverse shaft 9 which is suitably secured in the sides of the casing 10. The first three gear wheels 8 are larger than the remaining wheels and protrude through openings 11 formed in the top 12 of the casing 10, as shown by dotted lines in Fig. 3. Pawls 13 and 14 mounted upon a rod 15 are forced into engagement with the first three wheels 8 by coil springs 16 which surround the rod 15 and having their ends contacting with the rear side of said pawls, thereby preventing any accidental movement of the gear wheels. The pawls 14 are provided with tails 17 with which pins 18, projecting upwardly from a movable carriage 19, contact when the counter is placed upon the carriage as hereinafter described. The remaining gear wheels 8 are of the same size as the adding wheels and are inclosed by the casing 10 and the top 12, the latter being provided with openings 20 through which the numerals of each adding wheel may be seen. The openings 11 through which the first three gear wheels protrude have oflsets corresponding to the openings 20 through which the numerals on the adding wheels attached to said wheels may also be seen as shown in Fig. 8. Each adding wheel 7, except the last, is provided with two series of numerals from O to 9 and as any one of said wheels makes a half revolution one is transferred to the wheel of the next higher denomination by the following means: Projecting laterally from the first four gear wheels are pins 21 upon the outer ends of which are mounted pawls 22 that are normally forced toward ratchet wheels 23 attached to the numeral wheels of the next higher denomination by coil springs 24 which surround the pins 21 and have one end fast thereto while their opposite ends contact with the backs of pawls 22. Each of these pawls has projecting therefrom a pin 25 which contacts with the periphery of a disk 26 secured to the shaft 9 and thereby normally holds the pawl out of engagement with its ratchet wheel 23. Each of the disks 26 has two out out portions 27 into which the pin 25 enters so that its pawl 22 will engage with a tooth of the ratchet wheel 23 of a higher denomination and advance it one notch as the wheel of the next lower denomination passes from 9 to 0. This form of transfer is well known in the art and needs no further description here. The fourth and fifth gear wheels 8, reading from" the right in Fig. 3, are engaged by pawls 13 so as to prevent any retrograde movement but are free to be moved forward.

The fifth wheel is limited in its forward movement to its capacity, which is nine, by the following means: A pawl 28 somewhat similar to the pawls 14 is mounted upon the rod 15, see Fig. 5, and is forced into engagement with the periphery of the numeral wheel 7 by the spring 16. WVhen the wheel is rotated so as to bring the numeral 9 beneath the opening 20 the pawl 28 will enter a notch 29 formed in the wheel 7 and prevent any further forward movement of the wheel. The ratchet wheel 23 connected to this wheel is provided with only a sufficient number of teeth so that its pawl 22 will advance itonly from 0 to 9, after which the pawl 22 will ride upon the periphery of the wheel 23 when a transfer is to be made. The capacity of these counters is such that they greatly exceed the average sales of individual clerks and if any attempt is made to reset the counter by overrunning its capacity this look will act as a telltale. The top 12 is hinged at one end as at 30 and is provided at its other end with a lock 31 so as to secure it to the casing 10 and permit it to be opened to turn the counter wheels to zero.

As previously described the carriage 19 is provided with pins 18 which are arranged to pass through openings 32 formed in the bottom of the casing 10 and rock the pawls 14 out of engagement with the gear wheels 8 as the counter is placed upon said carriage. These pins also securely hold the counter in place upon the carriage. As the counter and carriage is drawn rearward by mechanism hereinafter described, pins 33 projecting laterally from the carriage will ride up sharp inclines 34 of slots 35 formed in standards 36 just at the end of the rearward movement of the carriage, and carry the protruding teeth of wheels 8 into the paths of rack bars 37 which cooperate with the rack bars 6, in which position the counter will remain until after spirally arranged cams 38 secured to a rotary shaft 39 move the rack bars 37 forward a distance equal to the previous rearward movement of the bars 6. This movement is effected by the cams engaging rollers 40 secured to the rear ends of said bars 6. The carriage and counter is then lowered and returned to its normal position, shown in Fig. 2.

The rack bars 6 are provided with slots 41 through which horizontal rods 42 extend to act as guides for said bars. On account of the direct transfer hereinbefore described it is necessary to actuate the rack bars 6 successively by the cams 38. The rack bars 37 are arranged beside the bars 6 and are supported by the rods 42 which project through slots 42 formed therein. These slots are inclined downward at their forward end so that when the racks are drawn rearward by coil springs 43 connecting them to the forward shaft 42, said racks will be raised out of the same horizontal plane with the teeth of the wheels 8 when the latter are in their raised positions. Each of the bars 37 is provided with counter operating rack .flteeth 37 and latch teeth 37".

Each bar 6 is provided with a pivoted pawl 6" arranged to engageteeth 37 and thus lock the bars together. Each pawl tends to move to engaging position by means of a spring 4O which connects it to its bar 6, and is normally held out of such engagement by an angular arm 38 connected thereto and engaged by a cam'39 on the rotation shaft 39. The grand total counter 43 is iimounted ina swinging frame 44 and is arranged to be given a reciprocating movement, after being swung rearward over rack plates 45 secured to the vertical rack bars so as to register the amount set up by the i levers 1 after which the operatin mechanism will swing the frame forwar and re turn the counter to its normal position, as

fully shown and described in the aforesaid patent to Thomas Carroll.

5 The timing of the above described mechanism is such that the grand total counter is registered upon and disengaged from the rack lates before the levers 1 and the rack ars 5 and 6 are returned to normal position by the cams 38. i

I ndz'catormechanisvm-The indicators are controlled by a series of adjustable levers which are returned to normal position at the 7 end of the operation of the machine leaving 5. the indicators latched in their adjusted positions. Each of the rack bars 5 is provided with an elongated slot 46 in the bottom of which rests a pin 47 projecting from the lower end of a rack bar 48, when thelevers J l and the indicators 49 are at zero. The rack bars 48 are also provided with an elongated slot similar to and in alinement with slots 46 ofthe rack'bars'5 and through which extends a guide bar 50.' The upper i ends of racks 48 engage'withdpinions 51secured to indicators 49 mounte loosely upon a =transverse shaft 52. As each lever 1 is moved downwardits rack bar 5 will be moved upward and carry with it the rack D bar 48 by means of the pin 47 resting in the bottom of the slot 45 thereby rotating its in dicator drum =49. Each drum is provided with aratchet wheel 53 on the side opposite to the pinion 5l,-with which a hook lever 54 I5 is held in engagement by a spring 55. The

lower ends of the levers 54 are arranged to E out' of engagement with their ratchets long to indicate $5.55 the levers 1 will be first moved to the latter position indicated by the indices on the cabinet (not shown). The shaft 57 is then revolved. The first movement will, through the cams 56, rock the upper ends of the levers out of engagement with the ratchets 53 and permit the springs 58 to return the indicators through the rack bars 48 until they are arrested by pins 47 contacting with the lower endsof the slots 46 after which the cams 56 will pass out of enf gagement with the levers 54 allowing the upper ends of said levers to engage the ratchet-s 53 and hold the indicators in this position, the levers l and rack bars 5 being then returned to normal position independent of the rack bars 48 by cams 38 contacting with the rollers 40 of the rack bars 6.

Operating mechanisvm-A crank handle 59, see Fig. 1, has attached thereto-a pinion 60 which meshes with a gear wheel 61 that e11 ages a similar gear 62 secured to one u en of the rotary shaft 57. An idler 63 meshes with the gear 62 and in turn engages a gear wheel'64 secured to the shaft 39. The

- pinion 60 is only half the size of the other 7 two turns of thegears, thereby requirin crank handle for a comp ete operationof the machine. A disk 65 is attached to the gear 61 and is provided with a cam groove 66 in which plays a pin 67' projecting from a forwardextension of an arm 68, which is pivoted at its upper end to the side frame of the machine. The lower end of the arm 68 is provided with a slot 69 into which rojects a pin 70 extending through an e ongated slot 71 of the side frame. A link 72, one end of which is pivoted to a rearward projection 73 of the carriage 19, carries the pin 70. The shape of the cam groove 65 the disk 65 will cam the arm 68 rearward, thereby carrying the carriage 19 rearward and upward and holding it in this position until the last'oneeighth of the rotation of disk 65, when the parts are returned to their normal positions. The gears 61, 62, disk 65 and the rest of the parts for reciprocating counter upon the carriage 19 which actre-' leases the locked registering wheels-7 by I is such that the first one-eighth of a turn of p to display the numeral 5. The crank handle 59 is then started which, through the cam disks 65, arms 68, pins and links 71, will draw the carriage 19 rearward and at the end of its rearward movement cam the carriage upward by pins 33 engaging inclines 34 of slots 35 of standards 36 thereby bringing the protruding teeth of the gear wheels 8 into the line of movement of the rack teeth 37*. During this movement the cam 56 secured to the shaft 57 will rock the hook ends of the levers 54 out of engagement with the ratchets 53, but the indicators not being in advance of the rack bars 5 will not be returned. After the cams 56 pass out of contact wit-h the levers 54 the latter will be drawn into engagement with the ratchets 53 by springs 55. After the detachable counter is cammed into position the levers 54 spring back into engagement with the ratchets 53 and thelast of the spirally arranged cams will contact with the roller 40 of the displaced dollar rack bar 6 and cam it back to normal position. Prior to this movement, however, the cam 39' has released the arm 38 and the pawl 6 engaged rack teeth37 to couple the rack bars together. As rack bar 6 moves forward the bar 37 moves forward and downward into mesh with the proper counter wheel to actuate or move the same five teeth. The carriage will then be lowered and returned to its normal position by the inclines 34 in the standards 36, disks 65, arm 68, pins 70 and links 71. Previous to the return of the rack bar 6 the grand total counter 43 will be drawn to the fear and then downward over the rack plate 45 of the displaced rack bar 5 and then disengage therefrom as fully shown and described in the aforementioned patent. When the cam again engages arms 38 the pawls 6 are moved downward and the rack bars 37 released and returned by their springs.

It will be seen from the foregoing description that while the counter wheels of one of the auxiliary counters might be unlocked by insert-ing some instrument through the apertures 32 these wheels could only be turned in a forward direct-ion, which would simply make the clerk accountable for more cash. The counter wheels even though they do project through the casing of the counter are locked against being turned backward at all times and also locked against any accidental turning when the counter is not in the clerks pocket or placed away in any sultable receptacle. It is only after the counter is inserted into the machine that the wheels are unlocked for forward rotation.

While I have shown one form of transfer mechanism for the counters it will be readily understood that any of the forms well known on the market might be substituted without departing from the spirit of this invention.

The independent movable counters may be kept in any suitable storage receptacle, but I prefer a drawer located in proximity to the register and divided into suitable labeled compartments for the counters. If the counters are to be employed for different clerks these clerks may simply slip their counters into their pockets or place them anywhere else where they will be inaccessible to other clerks. By this means a .clerk is absolutely assured that no one else would be able to register upon his counter.

It will, of course, be understood that the number of counters which may be employed is unlimited. I
