CASH-REGISTER.

SPECIFICATION forming' part of Letters Patent N 0. 683,877, dated October 1, 1901.

Application iiled April 30, 1898 To all whom t ntwy concern:

Beit known that I, THOMAS CARNEY, acitzen 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 toimprovements in cash-registers, and has more particular relation to that class of machines which print a record or detail strip of the transactions.

One of the several objects of the invention is the application of an improveddetail-strip printer to the type of machine patented to me March 19, 1895, and numbered 536,015.

The'invention consists of certain novel constructions, combinations, and arrangements of parts, all of which will be hereinafter more particularly set forth and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 represents a side elevation of thedevices embodying my invention applied to a machine of the type described and illustrated in the aforesaid Letters. Patent. Fig. 2 represents a top plan View of the same. Fig. 3 represents a vertical transverse section through the said machine. Fig. 3a represents a detail side elevation, partly in section, of the actuating parts :for the ive-cent-key bank; and Fig. 4 represents an enlarged detail view of the construction of the sleeves and pinions for actuating the printingwheels. Y t

In the said drawings,1 represents the frame of the machine, and 2 the printing-hammer or platen. The construction and operation of the keys, registering mechanism, and indicators are substantially the same as that described in the above-mentioned patent, and attention are therefore called to the same for a detail description of said devices. One exception to the above statement is that the keys are arranged in three banks, representing, respectively, a live-cent bank, a tens-ofcents bank, and a units-ofdollars bank. The single key 6 of the live-cent bank is arranged to operate a movable frame 7, While each of the keys 8 and 9 of the tens-ofcents bank is arranged to operate a movable frame 10 in Serial No. 679,324. (No model.)

practically the same manner as described in the aforesaid Letters Patent with a few exceptions hereinafter noted. The units-ofdollars keys 1l are arranged to actuate a movable frame 12, similar to the frame 10 and adapted to be operated in substantially the same manner. Each of the frames 7, 10, and 12 is connected to one of a series of operating rack- segments 13, 14, and 15, so as to operate the same and impart a greater or less movement, according to the value of the key pressed. Each of the keys 8, which representthe uneven multiples of five, has an equal actuating value with relation to the frame 10 as the preceding key 9, representing one of the even multiples of five, and will thus only move said frame to an equal extent. therefore necessary to actuate both of the frames 7 and 10 upon one of the keys S be-y ing depressed, and to accomplish this result I provide a journaled frame 16, mounted upon the pivot-shaft of the keys. This frame is provided on its underside with a plurality of spaced pendent lugs 17 so located as to lie directly over the inner portions of the keys 8. By this structure when any one of the keys Sis depressed the rear portion of the same contacts with the lug 17, lying above it, and thus raises and rocks the frame 16. This action of the frame causes a rearwardly-extending arm 18,mounted thereon, to be raisedA simultaneously therewith, and thus operate a vertical bar 19, pivotally connected thereto, said bar 19a operating the frame 7 in the manner of the usual bars described in saidpatent. The five-cent key, to which the bar 19 properly belongs, is not positively connectedthereto, but is adapted to strike one of the pendent projections 17 when operated, and thus rock the frame 16 and actuate the frame 7; otherwise the key 6 is practically the .same as the other keys both in construe* tion and operation.

By means of the above construction the five-cent-key frame 7 is operated upon the operation of any of the keys 8, as well as the key-frame proper, 10, of said keys, and the registration is thus recorded upon both the vecent counterwheel and the tens-of-cents counter-wheel. Any operation of the keys 9 IOO will simply result in the movement of the frame 10, as none of the projections 17 are located above said keys.

Each of the rack- segments 13,14, and 15 meshes with one of a series of pinions 19, 20, and 21, which are respectively connected to the printing-wheels 22, 23, and 24 as follows :Q

The pinion 19 is loosely mounted upon a shaft 25 and held in position thereon by a collar 25a and is provided with a sleeve 26, having a notch 27 formed therein for the reception ofr a lug 28, mounted upon a collar 29, which is secured rigidly -to the said shaft. The lug 28 is of less width than the notch 27, into which it projects, whereby in theV operation of alining the printing-Wheels just before the printing `operation the shaft 25 and the printin g-wheel 24, fast thereon, may be given a limited movement entirely independent of the pinion 19. This means to enable the exact alining of the types on the printing-wheels is a special feature of my present invention, because, contrary to many devi-ces of this kind, in myinvention the printing-wheels are always in positive engagement Withthe actuatingsegments. The pinions are `thereby rigidly held when the `segmentsare at rest after having completed their movement, and the printing wheels are positively moved by the actuatingdevices, yet the vconnection "issulnciently flexible to permit of an exact and proper alinement.. Th'epinions 2O and 21 are also constructed as above described` and have their respective collars mountedv on nested sleeves 29, which surround the lshaft25 and support the several remaining printing-wheels. By means of the abovef described connections the vprinting-ivheels 22,23, and 24 are moved through the medium ofthe segmental racks 13, 14, and 15 to an extent equal tothe values of the keys pressed. 1n orderto bring the desired characters of the` printing-wheels into proper alinement with the platen 2, eachy of said wheels is provided with a star-Wheel 30, which is arranged to be engaged by one-of a series of alining arms or pawls 31, formed on apivoted frame 32. This frame is provided with an operating-arm 33, having a nose 34 formed on its lower end and normally forced into engage-V mentwith a cam-wheel 35 by a coil-spring 36, which latter is mounted in a socketed lug 37, securedto the frame and engages the side of said arm. The said cam-wheel 35 is fast upon a revolution-shaft 38, which is rotated yupon the operationof a key by a double-acting loopfrack, substantially the same as described in the before-mentioned patent. The endless inking ribbon or t-ape 39 extends dircctly under the printing-wheels and passes about.antifriction-rollers 40, 41, and 42 and also about a feedingfroller 43, which latter is covered with a friction-felt to prevent slipping ofthe ribbon. Thisfelt is normally saturated with a suitable ink andv forms a source of ink-supply for the ribbon, so that the -same will be continually reinked as it passes over said roller. This roller 43 is provided with a gear wheel 44, meshing with an intermediate gear 45, which in turn meshes with a gear 46, journaled on the frame. The said latter gear'carries a ratchet-wheel 47 and a spool 48, the latter being arranged to rejceivethev detail-strip 49'and draw it forward after each printingoperation. The for-v ward step-by-step movement of the spool is effected by means of a spring-pressed hookpawl 50, which is mounted upon an arm 51, fast to the extended journal end 52 of lthe universal or key-coupling bar of the machine and receives motion therefrom. A

spring-pressed pawl 53a is also mounted on the frame and engages the ratchet-wheel 47 to prevent any backward movement of the same. The before-mentioned strip49 passes over two spaced supporting-bars 53 and 54l and under the ribbon 39 and is fed from a supply roller or spool 55. As the inking-ribbon may become stretched by constant use, I provide means for keeping it under tension at all times, and thus avoiding any slippingY on the feed-roller. This tension device comprises a pivoted yoke 56, in which is journaled a heavy,antifriction-roller 57, arranged to rest upon the inking-ribbon, and thus by its gravitatin g action keep the ribbont-aut at alltimes. yThe platen or printing-hammer 2, before nientioned,is preferably formed of rubber oroth'er resilient, material and ismounted on a pivoted arm 5 8, which is normally forced upwardby a spring59`,"inounted under the same. Said arm is depressed against the ten sion of the spring 59 by a camO, mounted on the 'revolutionshaft 38 and engaging a :nose 6l, formed on said arm. The construction of the cam 60 is such that the arm 58 is depressed gradually and then allowed tosuddenly Iiy back, so as to secure a hammeringl or tapping stroke of the platen. The outer end of the arm 58 is provided with Aav springpressed plunger-rod 62, which is adapted to contact with the bar 53. By this means the platen is first thrown up against the detail-v strip with the aforesaid tapping stroke and -then positively forced awayfrom the same by the plunger-rod and its spring.

It will be noticed that the printing devices are at all times in positive connection with the registering segments 13, 14, and 15, which form part of the operating mechanism.A

For the purposes of the claims I have referred to all of the operating parts from the keys to the registering segments as the operating mechanism, and it will be readily seen that the keys are alternately brought into and thrown out of coperative engagenient with the intermediatel devices between them and the printing devices upon each operation of the machine.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is j A 1. In a cash-register the combination with theoperating mechanism, the type-carriers IOO IIOy

which are in positive engagement with the operating mechanism, an alining means arranged to be operated while the type-carriers and the operating mechanism are in such positive engagement and a flexible connection between the type-carriers and the operating mechanism whereby the former may have limited movements independent of their operation through said movable connection, substantially as described.

2. In a cash-register the combination with the operatin g mechanism, of a shaft surrounded by one or more hollow shafts, type-carriers in positive engagement with the operating mechanism through said shafts, means for setting said type-carriers by the initial movement of the operating mechanism, means for moving the record-strip against the type-carriers, an alining mechanism for the type-carriers and a exible connection with which said shafts are provided whereby the typecarriers are first positively moved approximately to printing position by the operating mechanism and then alined independently of their movements through said movable connection and prior to the operation of the devices for pressing the record-strip against the type-carriers, substantially as described.

3. In a cash-register, the combination with a Series of keys, of a printing mechanism, a record-strip-winding roller, a ratchet-wheel on said roller, a movable member common to all of the keys and having an extended journal end, a rigid armon said journal end and an operating-pawl mounted on said arm and engaging said ratchet-wheel.

4. In a cash-register, the combination with an operating mechanism, of printing devices arranged to be operated thereby, alinin g means for said devices, and means for connecting the operating mechanism and the printing devices but allowing the latter to be alined independently of such connection.

5. In a cash-register, the combination with a series of keys, of printing devices, alining means for said devices, and means connecting said keys and printing devices including` notched collars and collars having projections which enter said notches, the construction being such that the printing devices may be alined independently of their regular connection with the keys.

6. In a cash-register, the combination with an operating mechanism, oli-printing devices arranged to be operated thereby, alining means for said devices, and means for establishing a connection between the operating mechanism and the printing devices but allowing the latter to be alined independently of said connection with the operating mechanism.

7. In a `cash-register the combination with an operating mechanism of a plurality of printing wheels, alining devices for said wheels connected to the moving parts of the machine, and means connecting the operating mechanism with the printing-wheels for moving the latter but at the same time allowing them to be alined independently of such connection.

8. In a cash-register the combination with a plurality ofvoperating-racks, of a shaft, nested sleeves mounted over said shaft, collars fast on said shaft. and sleeves and each formed with a projection, pinions meshing with the racks and each formed with a recess to receive its respective projection, printingwheels mounted on said shaft and sleeves and alining devices for said wheels.

9. In acash-register, the combination with a series of keys, of a printing mechanism, a record-strip-windin g roller having a ratchetwheel, an inking-ribbon, a feeding-roller for the same, means connecting said feedingroller with the winding-roller so that they move simultaneously, a movable member common to all of the keys, an arm mounted rigidly on said member and a pawl mounted on said arm and engaging said ratchet-wheel.

In testimony whereof I affix my signature' in the presence of two witnesses.
