CASH-REGISTER.

SPECIFICATION forming part of Letters Patent No. 707,195, dated August 19, 1902.

Application filed July 11, 1898. Serial No. 685,655- (No model.)

' To to whom it may concern.-

Be it known that I, FAYETTE B. BARNARD, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and usef ullmprovements 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 machines of the type employing check and detail strip printers.

The present invention is an improvement on the class of machine patented to Thomas Carney, No. 497, 860, dated May23,1893, and attention is therefore called to said patent.

One of the several objects of the invention is to provide improved means in a machine of the class mentioned for printing both a check and a detail-record strip.

In the appended drawings, forming part of this specification, Figure 1 represents a top plan view of the devices embodying my invention applied to a machine of the type mentioned. Fig. 2 represents a side elevation of the same. Fig. 3 represents a vertical transversesectionthroughsaid machine,the drawer and casing being omitted. Fig. 1 represents an enlarged detail side elevation of the ribbon-feeding mechanism. Fig. 5 represents an enlarged detail perspective view of one of the shifting-levers, showing its attachment to the ink-ribbon. Fig. 6 represents an enlarged detail perspective view of the ribbon-feeding slides, and Fig. 7 represents an enlarged detail side elevation of the locking devices shown in dotted lines in Fig. 3.

In the aforesaid drawings, 1 represents the frame of the machine, 2 the keys, and S the slidable printing-bars. The construction and operation of the keys and registering and in dicating devices is substantially the same as describedin the above-mentioned patent, and attention is therefore directed to the same for a detail description of the parts. The said keys in the present instance are divided into three groups or banks representing, respectively, units of cents, tens of cents, and units of dollars; but this capacity may be either increased or decreased without departing from the spirit of my invention. Each of the aforesaid keys is provided forward of its pivot-point with a laterally-projecting stud 4, which is adapted to pass into an openended cam-slot 5, formed in one of a series of plates 6. Each of these slots has an approximately vertical portion 5, an inclined portion 5", and an end dip 5, whereby the keys may move at both ends of their strokes independently of the said plates. The said plates of the units-of-dollars bank are fast upon a transverse rock-shaft '7 and are so arranged in relation to the same that the cam-slots extend at different angles thereto, whereby the said shaft is rocked either to a greater or less extent, according to the value of the key operated. The remaining banks of keys, representing the units of cents and tens of cents, are also provided with similar cam-slotted plates, which are secured, respectively, to nested sleeves 8 and 9, mounted loosely upon each other and upon the shaft 7, so as to be capable of movement independently of said shaft and of each other. Each of said sleeves, as well as the shaft, is provided with one of a series'of locking-sleeves 10, fast thereto and formed with a notched lug 11. Each of these lugs is normally engaged and locked in position against movement in either direction by the nose 12 of one of a series of locking-levers 13, said lever being carried by one of a series of yokcs 14, pivoted on the key-shaft and extending below its respective bank of keys.

It will be observed from the above that each bank of keys is provided with one of the yokes 14, so that when any key in a bank is depressed it engages its yoke and moves the same downward against the tension of a spring 15, which normally supports it in its upper position, and thus operates its arm 13 to release the operating-shaft 7 or sleeves S and 9, as the case may be. By this means the operatingshaft and the two sleeves are positively locked against any accidental or fraudulent movement and cannot be operated until one of their respective keys is partly depressed, said key being prevented from being retracted until it has made its full stroke, as described in the aforesaid patent.

The

said shaft 7 and sleeves 8 and 9 extend beyond the frame 1 of the machine at one end different distances and are each provided with a rigid arm 16, formed with a longitudinal notch or slot 17 at its outer end. The typebars 3 3, which are movably mounted in slotted brackets 18, are each provided with a laterally-projecting stud 19, which projects into the slot 17 of its respective arm 16, so that when the latter is operated the bar will be moved to the necessary extent to bring the desired type into the proper printing position. Each of the said type-barsis formed both top and bottom with printing-type, so that an impression may be secured both above and below the same. In order to secure an inking means for both sides of the bars, I provide an inking-ribbon 19* and pass the same over antifriction-rollers 20, arranged on opposite sides of said bars and above and below the same. This ribbon passes downward over guiding-rollers 21 and has its respective ends secured to spools or reels 22 and 23, journaled on a frame 24. Each of these reels is provided with a ratchet-wheel 25, by means of which it is fed forward to wind the ribbon thereon. The winding is accomplished by spring-pressed pawls 26, mounted on a slidable cross bar 27, which in turn is loosely mounted in a vertical slide 28. This vertical slide is suitably mounted in the frame 24 and is provided at its upper end with an angular slotted arm 29, which will be hereinafter more particularly described. The lower por tion of the vertical slide is formed with a transverse groove 30, in which the said bar 27 is loosely mounted, so as to be capable of sliding horizontally. The pawls 26 are limited in their movements and prevented from being forced too far forward under the tension of their, respective springs 31 by lugs 32, with which they are provided, contacting with stop-pins 33, mounted on the slide 27. The relative arrangement of the said pawls and stops is such that when one pawl is engaging its ratchet-wheel 25 the other will be disengaged from its ratchet-wheel. In order to prevent any backward movement of the said ratchetwvheels, two gravity-pawls 34 34 are pivoted on the frame 24 in proximity to the said wheels and are arranged to be withdrawn from contact with said wheels by pins or studs 35, mounted on the slide 27. \Vhen said slide is moved in one direction, one of said pins 35 disengages from its pawl 34 and allows the latter to fall into engagement with its ratchet-wheel, while the remaining pin 35 engages the remaining pawl and forces it out of engagement with its ratchet-wheel. The structure of said pawls is such that the predominating weight of each is thrown to one side of its pivot-point, and said pawl thus held to engagement with its wheel by gravity. The aforesaid slide 27 is moved from one side to the other to reverse the movements of the inking-ribbon by a lever 36, mounted on the frame 24 and provided with an operating-pin 37, which extends through a suitable slot formed in the frame and enters a vertical groove 39, formed in said slide 27. The upper end of the lever 36 is formed with two diverging arms 40, which are arranged to be struck and operated by pivoted arms 41, mounted on the respective reels 22 and each provided with a pin 42, to which the end of the ribbon is attached, said pin working through a slot in one of the reel flanges. Then the ribbon has become exhausted from one of the reels, its respective arm 41 is drawn outward and striking one of the arms 40 operates the lever 36 and moves the slide 27 to shift the pawls and cause the ribbon to be reversed. The lower end of the said lever 36 is formed with two spaced notches, into which a teat 43 of the said reels, according to the position of.

the slide 27. This reciprocation of the slide 28 is effected through the medium of the angular slotted arm 29,which projects into proximity to a bell-crank platen-arm 44, where by a pin 45, mounted on said arm, projects into the slot of said slotted arm. The lower portion of said platen-arm is provided with a resilient platen 46, arranged to force the detail-strip into contact with the under side of the type-bars, while the upper portion is formed with an angular slot 47 for the reception of a crank-pin 48, mounted on a crankarm 49, which in turn is fast upon one of the journal ends of the key-coupler 50. The said platen-lever is further provided with a stud 51, which projects into a slot 52 in the upper platen-lever 53, which is pivoted on the frame and carries a platen 54 similar to the platen 46. It will be observed that by this structure both of the platen-levers are simultaneously operated to bring the respective platens into printing positions. In addition to the stud 51 the lever 44 is provided with a gravity-pawl 55, which engages a ratchet-wheel 56, mounted on a winding-spool 57, which is adapted to receive the record-strip 58 from a supply-spool 59 after said strip has passed over the spool-supporting bracket 60. Any backward movement of the spool 57 is prevented by a hook-pawl 61, pivoted on the frame and engaging the said ratchet-wheel 56.

It will be seen from the foregoing description that upon each operation of the machine both the inking-ribbon and the record-strip are moved forward one step, so as to be ready for the succeeding operation of the machine. When it is desired to print a check as well as the detail-strip, a suitable check is inserted in an inverted position under the platen 54 through a suitable slot in the printer-casing, so as to be forced downward upon the operation of the machine.

I do not care to limit myself to the application of my invention to any particular type of registering mechanism, as the same may be applied to operate counters, printing mechanisms, indicators, or any other form of indieating or registering devices without departing from the spirit of my invention.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is
