WILLIAM H. MUZZY, OF DAYTON, OHIO, ASSIGNOR TO NATIONAL CASH REGISTER COMPANY, OF JERSEY CITY, NEW JERSEY, A CORPORATION OF NEW JERSEY.

CASH-REGISTER.

SPECIFICATION forming part of Letters Patent No. 7'7 5,088, dated November 15, 1904.

I Application filed March 15, 1904. Serial No. 198,221. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM 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-registers, and has more particular relation to improvements in registers of the type patented to Watson and McGraw, No. 686, 683, dated November 12, 1901.

One of the several objects of the invention is to provide the type of machine mentioned construction and combinations of parts, the es-.

sential elements of which are set forth in appended claims and a preferred form of embodiment of which is hereinafter specifically described, with reference to the drawings which accompany and form part of this specification.

Of said drawings, Figure 1 represents a front elevation, partly in section, of a machine of the type mentioned with my improvements applied thereto, the cabinet and cash-drawer being omitted. Fig. 2 represents a transverse vertical section through the same on the line 2 2 of Fig. 1. Fig. 3 represents a similar section through the machine on the line 3 3 of Fig. 1. Fig. t represents a detail top plan View of the nested sleeves and connections for supporting and operating the printing-segments. Fig. 5 represents an end elevation of the machine, showing the printing mechanism; and Fig. 6 represents a detail side elevation of the devices for throwing out the counter when it is desired to record certain transactions Without registering them.

As many of the parts shown in the present drawings are substantially identical in construction and operation to the corresponding parts shown in the aforesaid patent, I will re fer to the latter for such detail descriptions as are not hereinafter given. Described in general terms, however, it may be said that the machine comprises a series of operatingkeys which are normally locked and are released by an independent release-key, this release-key also releasing any of the rotary indicators which have been previously set by the keys and left in their set or exposed positions when the keys returned to their normal positions. The operation of any one of the amount-keys results in a graduated movement of a rack segment. This segment through suitable intermediate gearing actuates the counter-wheels.

Described more in detail, each of the keylevers 3 is pivoted upon a transverse shaft 2, which is mounted in the main frame 1 of the machine. Each lever is normally drawn downward at its rear ends by a coil-spring 4, which connects it to a rigid cross-bar 5, the movement of the lever being limited by a cross-bar 6 of the main frame located forward of the pivotal shaft 2. The amount-key levers are arranged in banks and are numbered from 1 to 9, respectively. The key-lever of any particular bank when operated is arranged to contact with and actuate a stepped cross-bar 7 which, as best shown in Fig. 1, connects an arm 8,mounted loosely on the shaft 2, to the bell-crank rock-lever 9, also mounted loosely on said shaft. The levers 8 and 9, together with the cross-bar 7, form a yokeframe over their particular set of keys, which frame is constructed to be actuated difierentially according to the value of the key operated. As these yoke-frames of each bank, excepting the special bank, are substantially identical, I will describe one only,;as this description will suflice for all. 7

Each of the levers 9 is provided upon its opposite ends with segmental racks 10 and 11 and is drawn into the normal position (shown in Fig. 2) by a coil-spring 12, which connects it to the cross-bar 13 of the main frame. The

segmental rack 10 meshes with rack-teeth formed on a vertically-movable bar 14, which is guided in cross-bars and 16 of the main frame and is provided with a series of rackteeth 17 and a series of ratchet-teeth 18 upon its rear side. The teeth 17 mesh with pinions 19, mounted upon the inner ends of aseries of nested sleeves 20 and the supportingshaft 21, said shaft and sleeves being provided at their outer ends with the type-segments 22, representing the amounts, and the special type-segment 23, representing the special transactions, as clearly shown in Figs. 1 and 4. The said bars are also provided near their upper ends with a series of rackteeth 24, which mesh with pinions 25, secured to the respective indicator-wheels 26, which are loosely mounted upon the transverse supporting-shaft 27. The indicator for the dollars-bank, as shown in Fig. 1, is provided with a reversely-arranged double set of numerals representing O to 9, inclusive,and arranged to be disclosed at both the back and front of the machine. The indicators for the tens-of-cents bank and the units-of-cents bank are substantially identical, excepting that in addition to the reversely-arranged sets of numerals each of the same is provided with a third series of ten zero characters. The object of this third series of characters is to provide the proper zeros for the tens of cents to be read properly from the opposite sides of the machine. Thus the indication of fifty cents would read with the zero upon the units-of-cents indicator and the five upon the.

tens-of-cents indicator, while the corresponding indicatlon at the back of the machine would read entirely upon the tens-of-centsin;

dicator. For this purpose the indicator-apertures in the cabinet are so arranged that the operation of the machine will disclose, at the front of the machine the right-hand se ries of numerals of the tens-of-cents indicator and the lefthand series of numeralsof the units-of-cents indicator. The indication at the back of the machine will show thetwo left-hand series of numerals on the tensofcents indicator and the two right-hand se? ries of numerals in the units-of-cents indicator.

It will be seen from the aforesaid description that the movement of any one of the racks 10 will result in the corresponding movement of its bar let and the indicatorwheel and type-segment controlled thereby. hen the indicator and type-wheel have been so set, means must be provided for latching them in this set position to prevent their return under the impulses of the springs 12 when the key returns. This latching means comprises a rock-shaft 28, mounted transversely of the machine and provided with radially-projecting pins 29, which project into elongated slots 30, formed in a sleeve 31, which loosely surrounds shaft 28. Attached to this sleeve 31 are aseries of angular spring retaining-pawls 32, which are normally held to engagement with the rack-teeth 18 by means of V-shaped arms 33, pendent from the sleeve 31 and engaged by V-shaped noses 34:, formed on pivoted pawls 35, which are suitably mounted upon the main frame. The pawls are normally forced upward by coil-springs 36, interposed between them, and the bar 13, as plainly shown in Figs. 2; and 4. It will be seen that the upper inclined rearside of each nose 34 normally engages the forward inclined side of each arm 33, and thus holds all of the retaining-pawls 32 yield igngly in. engagement with the ratchet-teeth 118. Located approximately at the middle of the machine is a release-key bar 37, which extends through a suitable aperture in the front of the machine and is provided with an; operating head or button 38, by means of which it may be forced; inward against the tension of the coil-spring 39, which connects it to the main frame. The rear end of the bar-3f7fis. pivotally COHIIOCtGdi to a shaft 37 transverse rock-shaft 28', whereby when said key 37 is forced rearward the shaft 28 is correspondingly-nockedi. Each of the arms 10 carries a ratchet-plate &1, which is engagedl by a piwoted, pendent spring-drawn pawl 42,. suitably mounted; on, the main frame and coacting-witlrsaictp1ates4l to compel full movement of the. arms 4,0,in both directions in a manner well known in the art.

(hen the bar 37;is initially forced inward; torelease the indicators, the sleeve 31 remains stationary, as the shaft 28 is free to rock a certain, distance before the pins 29 come into contact with the rear Walls of the slots 30, formed; in, the sleeve. The continued rearward movement of the bar 37 now rocks the sleeve,31 to, disengage the pawls 32 from the ratchet teethJSu This rockingof the sleeve 31 causesthe arms 33 to depress the reanends jof the. pawls 35 until said arms pass entirely over-thenoses 3 1, when the pawls 35 rise under the impulseof their springs, and thus engage. the rear faces of the arms As the pins 29,at this time are in the rear portion of the slots 30, thesleeve 31 is free to move independently rearward. This independent movement of the sleeve is very rapid and is of sufficient extent to totally disengage all of the spring-pawls32 from their ratchet-teeth 18 to release the bars 14 and allow them to assume their normal positions. Inmachines of the type above mentioned the inaccuracies of manufacture cause the pawls 32 to disengage from the ratchet teeth 18 and the bars 14. at;

different periods if the bar 37 is moved slowly:

tion at present employed in this type of machine permits of the machine being man1pu-- which has its opposite ends: mounted in arms. 4-0, which are fast to the pawls 32 can be disengaged from its ratchetteeth 18 before the remaining pawls. disengaging movement is automatic and is virtually beyond the control of the operator, as such movement of the pawls is controlled by the springs 36 and could not possibly be arrested by the operator by any manipulation of the bar 37. Further, after the pawls 32 start their movement to disengage from the ratchet-teeth they cannot again engage said teeth until the bar 37 has been pressed inward fully, as the pawl 42 prevents any retrograde movement of said bar 37 until the same is fully operated.

As above stated, the detail description be fore given refers particularly to the banks of keys pertaining to the amounts; but this description also applies in part to the bank of special keys 43. These keys, as best shown in Fig. 3, are arranged in substantially the same manner as the amount-keys and cooperate with a special operating-frame 44. This frame is connected to its particular indicator in substantially the same manner as the frame pertaining to the amount-banks. This particular frame 44, however, is not provided with a counter-operating rack-segment 11. Each of these special keys, however, is provided with a pivoted spring-pressed pawl 45, which engages a ratchet-wheel 46 for operating one of a series of special counters 47 for keeping track of the number of times each of the special keys is operated in a manner well-known in the art. Further, each of these keys 43 when depressed is arranged to contact with a transverse bar 48, which connects two arms 49, loosely mounted upon the shaft 2, to form a special operating-yoke for the bank of special keys. The link-bar 50 connects this yoke to an arm 51, mounted upon a sleeve 52, which in turn is mounted upon the transverse supporting-shaft 53, as best shown in Figs. 1 and 3.

From the above construction it results that when any one of the special keys is depressed the sleeve 52 is rocked forward. This forward movement of the sleeve causes the series of vertically-arranged, arms 54, mounted thereon, to engage the rear ends of pawls 55, which are carried by disks 56, to move said pawls upon their pivots 57 and out of engagement with ratchet-wheels 58, which are connected to the respective counterwheels 59. When the pawls 55 are rocked out of engagement with the ratchets 58in the man'- ner above described, laterally-projecting pins 59 mounted thereon pass through notches 60,

The

formed in stationary rings 61, mounted rigidly beside the disks 56 by means of arms 62, as best shown in Fig. 6. Each of the disks 56 is mounted upon a sleeve 63, which carries a pinion 64, meshing with its respective operating rack-segment 11. Each of the pawls 55 is normally drawn into engagement with its respective ratchet-wheel 58 by a coilspring 55, which connects it to the disk 56.

It will be seen from the above that when the disks 56 are rotated by the operation of the keys 3 they normally operate the registering-wheels to a degree corresponding with the values of the keys operated. When the pawls are thrown out in the manner above described, the movements of the disks 56 simply result in moving the pins 59 over the rings or flanges 61, whereby the pawl is held out of engagement with its ratchet-wheel 58 during its entire forward stroke and only reengages said wheel again when the disk 56 resumes its normal position, whereby the pin 59 can again pass through the notch 60. There is sufficient clearance between the pin 59 and the inner surface of the ring 61 to allow the pawl 55 toride back'over the teeth of the ratchet 58 during the normal operation of the machine. It will be seen from the above description that when any one of the special keys is actuated the counting mechan- 5 ism will be thrown out, so that while the indicators will be set to indicate the proper amount no registration will take place.

As before stated, the setting of the different graduated frames, whether they be amountframes or the frame pertaining 'to the bank of special keys, sets the type-carriers 22 and 23 for printing both the amount of thetransaction and also the characterof the transaction. By reference to Fig. 1 it will be seen that when the type-carrier 23 is in its normal position the dollar-sign will be printed in connection with any amount printed. When this special type-carrier is moved, however, from its normal position, characters will be printed in connection with the amount characters for indicating whether. the transaction is No sale, Paid out, Received. on account, or a Charge.

If the type-carriers have been set as above described, an impression. is taken upon the detail-strip 65 by means of a platen 66. This platen is mounted on an angular platen-arm 67, as best shown in Figs, 1 and 5. The arm 67 is connected to a slide 68, which is mounted upon the main frame by headed bolts 69, which pass through elongated slots 70, formed therein. The platen-bar 68 normally tends to move toward the type-segments under the impulse of the coil-spring 71, which connects said bar to a pin 72, mounted on the main frame. The bar is held, however, in its retracted position (shown in Fig. 5) by a sliding latchbar 73, mounted upon the main frame by means of headed screws 74, which pass through IIO &

slots 7 5, formed therein. The upper end of the slide 73 is beveled and cooperates with a beveled lug 76, formed on the bar 68. The lower end of the slide 73 is provided with a lug 77, against which the bell-crank trippinglever 78 is normally drawn by means of a coilspring 79, which connects the lever to the main frame. The slide 73 is normally held in its latching position by a coil-spring 80, which connects it to the main frame. One end of the bell-crank lever 78 is beveled upon one side and projects into the path of the antifriction-roller 81, which extends through a segmental slot 82, formed in the main frame, and is carried by a pivoted yoke-frame 83, extending under all of the levers and operated by the depression of any one of the same. This frame is normally drawn upward against the under edges of the keys by a coil-spring 8 1, which connects it to the main frame.

It will be seen from the above description that when any one of the keys is depressed the roller 81 will move downward and engaging the bell-crank lever 78 will rock the same upon its pivot without affecting the latch 73. When the key returns toward its normal position, however, and permits the frame 83 to move upward, the roller 81 will engage the lever 78 and rock the same in the opposite direction, which will cause the lever to retract the slide 73 and release the platen. When the platen is so released, it springs forward because of the tension of the spring 71 and strikes a hammer-blow upon the detail-stri p 65, forcing the latter, together with the end less inking-ribbon 85, against the types in printing position. The platen is slightly retracted after striking its hammer-blow by a small coil-spring 86, mounted in the upper wall of one of the slots 70 and arranged to engage its respective bolt 69 when the platen descends. After the platen has been operated, as above described, it is again recocked by the operation of the key 38 and the rocking thereby of the shaft 28. This shaft, as best shown in Fig. 5', is extended through the side plate of the machine and is provided with a crank-arm 87. This arm is connected to a toggle-link 88 by means of a headed bolt 89, which passes through an elongated slot 90, formed in the link. The upper end of this link is pivotally connected to the platen-bar 68. When the platen is released and descends, the link 88 passes down and rearward independent of any movement of the arm 87 the pin 89 meanwhile passing from one end of the slot 90 to the other. hen the key 38 is depressed previous to the subseqent operation of the keys, the arm 87 is moved upward at its forward end by the rocking of the shaft 28, and the toggle formed by this arm and the link 88 is thus straightened out and the bar 68 forced upward and forward sufficiently to again become latched. When pressure upon the key 38 is removed, the shaft 28 and arm 87 automatically resume their normal positions, (shown in Fig. 5,) so that the platen 68 is again free to descend when released without interference from the arm 87.

The endless inking-ribbon 85 is guided on suitable supporting-studs 92 and passes about an absorbent ink-roller 93, which is journaled upon the main frame. This roller is provided with a ratchet-wheel 94, which is engaged by a restraining-pawl 95 and is arranged to be actuated by a spring-pressed pawl 96, mounted upon the arm 97, which is fast to the shaft 28. The inking-ribbon is thus fed forward a slight distance upon each operation of the machine. The detail-strip passes from the supply-roller 98 over suitable guiding-studs 99 and about the feeding-roller 100. This roller carries a ratchet-Wheel 101, which is engaged by a restraining-pawl 102 and also by a spring feeding-pawl 103, mounted upon the platen-bar 68. By this means the detailstrip is fed forward to bring a fresh space into printing position upon each recocking movement of the platen-bar 68.

It will be observed that when an amountkey is operated the indicators and type-segments are first set by the downward movement of the key. After being so set the indicators and type-segments are latched in such set positions, whereby they are unaffected by the return movements of the keys. During this return movement the platen is released and prints upon the detail-strip the numerals and character set up by the keys previously operated. The only additional work which the keys must perform is the setting of the typesegments and the releasing of the platen, the duty of recoeking the platen against the tension of the spring 71 being thrown upon the releasing-key 38, thus preventing any overloading of the amount or special keys.

It will of course be understood that other forms of platens or strips and ink-ribbon-feeding devices might be employed in connection with the present improvements without departing from the spirit of this invention. I also do not care to limit myself to the particular construction of devices for automatically and simultaneously disengaging all of the ratchet-pawls from their respective ratchets, as numerous other constructions varying in detail but not in principle might be employed to accomplish this same result.

In order to prevent any possibility of any one of the special vkeys being operated after the amount-keys have been displaced from their normal position and also to prevent the simultaneous operation of more than one key in each bank, I provide a series of pivoted key-stops 14: and 14:. The stops 1 1 are pivotally mounted upon the cross-bar of the main frame and are formed at their upper ends with wedge-shaped heads 1 1", which lie directly beneath the special key-levers 13. When any one of the special keys is operated, the keystops 1A are forced both to the right and left in order to permit the descent of the lever.

. After any one of the key-levers has been fully depressed the stops 14 are again freed. This peculiar action of the stops 14: is utilized to lock all of the amount-keys during the time that the special keys are being depressed. To accomplish this result, the left-hand stop 1A is provided with a pin 15, which projects into an elongated slot 15 formed in a link-bar 15. The bar 15 is pivotally connected to a special key-stop 16*, which is in turn connected to a similar stop 16 by link-bar 16. The stop 16 is connected by link-bar 17 to the extreme right-hand key-stop 14!. All of the key-stops 14* are suitably pivoted upon the main frame and are beveled at their upper ends and constructed to prevent the simultaneous operation of more than one key in the same bank. Should an amount-key be operated first, the right-hand displacement of the stops 14 will cause the link-bar 15 to move to the right until the end of the slot 15 contacts with the pin 15. As none of the keystops 14 can now move to the left, the special keys are locked and remain so until the amount-key is returned to its normal position. Whenever a special key is partly depressed, the pin 15 moves to the left end of the slot 15", and the special key-stops 16 16 and the right-hand key-stop 14 are thereby locked against movement to the right, which prevents the operation of a key in any one of the amount-banks. As the general operation of these key-stops is so well understood in the art, no further description of the same is thought to be necessary.

While the form of mechanism here shown and described is admirably adapted to fulfil the objects primarily stated, it is to be understood that 1 do not care to confine myself to any form of embodiment of the invention here disclosed, for it is susceptible of embodiment in various forms, all coming within the scope of the claims which follow.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is
