CASH INDICATOR AND REGISTER.

SPECIFICATION forming part of Letters Patent No. 383,006, dated May 15, 1888.

Application filed January 19, 1887. Serial No. 224,768. (No model.)

To all whom it may concern.-

Be it known that I, JOHN H. PATTERSON, a citizen of the United States, residing at Day ton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Cash Registers and Indicators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to improvements in cash registers and indicators designed for the use of store-keepers and others as a means of accurately registering the total receipts forany given period of time and for indicating to the customers that the amounts paid have been registered by disclosing to their view such amounts on figured tablets.

It has for its object an improvement in this class of machines whereby their construction is simplified and their efficiency rendered more nearly perfect.

The novelty of my invention will be herein set forth, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1, Sheet 1, is a front elevation of a machine embodying my presentinventiou. Fig. 2, Sheet 2, is a rear elevation of the same with a porchecks.

tion of the case broken away. Fig. 3, Sheet 3, is a side elevation of the same With the end of the case removed. Fig. 4, Sheet '3, is a sectional plan View of one of the rocking tablets. Fig. 5, Sheet 3, is asectional detail representing a modification of the sliding till-cover. Fig. 6, Sheet 3, is a plan view of one of the Fig. 7, Sheet 4, is a side elevation of the machine with the end of the case removed and portions broken away to show the regis tering mechanism. Fig. 8, Sheet 4, is an en larged rear elevation of one of the registeringwheels and its three operating-keys in section.

The same letters of reference are used to indicate identical parts in all the figures.

The machine proper is inclosed in a case or cabinet, A, of the usual or any suitable construction,and provided in this instance with a rounded or cylindrical top, with glass-covered reading-openings B O at its front and back, respectively, through which the numbers on the rocking tablets are exposed to view.

The frame-work of the machine is substantially like that shown and described in Patents Nos. 318,485, of May 26, 1885, and 321,988, of July 14, 1885, and it'is only necessary to say here that G is the vibrating frame; D,the operating-keys; E, the tripping-arms; G, the gong, and H the hammers.

The registering mechanism (illustrated in Figs. 7 and 8) is preferably that shown and described in Patent No. 351,460, of October 26, 1886, though any other suitable registering mechanism adapted to be operated by the keys to register the value ofeach key might be substituted.

Instead of a tablet-rod and tablet for each key,l provide the following mechanism: Upon a shaft, I, extending across the top of the frame-work, are strung a number of rocking tablets, J, which in this instance are composed of a hub, a, Fig. 4, two spokes or arms, b c, and a cylindrical periphery the outer side of which bears the figures to be exposed through the openings B 0. These rocking tablets are each free to turn independently of the other and are operated by rods or arms K, pivoted at their lower ends, one to each of the keys D, and to avoid the necessity of having as many rocking tablets as there are keys I have in the present instance grouped three keys and their rodsK to each tablet in the following manner: Slots d efare cut through the arm I) of the tablet, through which the upper ends of the three rods K pass, respectively, and each of the rods K is provided with afinger, g, to form a catch or projection that engages with a pin, h, in each of the slots'whenever its key is oper ated.

It will be observed that the pins h in the slots 01 e f are at a gradually-decreasing distance from the axis of the tablet in the order named, for the following purpose and reasons: Beginning with the first tablet to the left, to which are connected by their rods K the first three keys,and supposing that these keys have a fixed value of five, ten, and fifteen cents, respectively, and inasmuch as the keys have an equal extent of travel and vibration, it will be seen that when the five'cent key is operated its catch or projection on the rod K, which passes through the slot d, would engage with the pin h at a point farthest from the axis of the tablet and would move it just sufficiently to expose the number 5 upon the tablet through the reading-openings B and O. The catch or projection on the rod K of the ten-cent key by engaging the pin it of the slot 6, which is nearer the axis,'would move the tablet still farther to expose the number 10 through the reading-openings, while the rod K of the fifteen-cent key by engaging the pin hot the slot f, which is still nearer the axis, would move the tablet still farther to expose the number 15 through the readi rig-openings. The next rocking tablet would bear on each of its two opposite sides the numbers 20, 25, and 30 and be operated by the twenty,twenty-five,and thirty cent keys,in the manner above described. The next rocking tablet would bear on each of its two opposite sides the numbers 35, 40, and 45, as shown in Fig. 2, and be operated by the thirtytive, forty, and fortyfive cent keys, in the same manner, and so on throughout the series.

Instead of placing the pins h at varying distances from the axis,they might be at an equal distance from it and the same result be accomplished by varying the distance of the fingers g from the keys D. Thus the finger g on the rod of the five-cent key might be located at a point nearer the keys than the fingers on the rods of the ten and fifteen centkeys, the finger on the rod of the ten-cent key being the next nearest and that on the rod of the fifteen-cent key the farthest, so that were the fivecent key to be operated the finger 9 upon its rod K would not engage the pin it of the slot (1 until the rear end of the key had been elevated to almost its farthest 1in1it, and thus the tablet would be moved only suffieiently to expose the number 5 throughthe readingopening. Then the ten-cent key was operated, the tinger g on its rod K would engage with the pin it in the slot 0 at an earlier point in the operation of the key and would move the tablet still farther to expose the number 10 through the reading-openings. \Vhen the iitteeneent key was operated, the finger g on its rod K would engage with the pin it in the slotf as soon as the front of the key had been slightly depressed, and when the key was depressed to its farthest limit would move the tablet far enough to expose the number 15 through the reading-openings,and so on through the series. In this instance the arm 6 is made suificiently large to constitute a weight for automatically returning the tablet to its normal position, though any form of weight or even a spring might be employed for this purpose.

To hold the tablet with its number exposed after any key has been operated, I provide a series of ratchet-teeth or retaining-points, t, upon the hub of each of the tablets,and a sh aft, L, Fig. 2, which extends across the frame and carries a series of dogs, M, one for each of the tablets, and engaging with its ratchet-teeth '27. At one end of said shaft,and secured thereon, is an arm, N, whose lower end is pivoted to the draw-bar F, and whose upper end is pro vided with the gong-hammer H.

O is any suitablezretracting-spring, applied to the arm N for throwing the same back and causing the hammer to strike the gong whenever any key has been operated to its fullest extent. It results from this construction that whenever any key D, the series of which rest and are supported at their forward ends upon the frame 0, is operated the frame 0, in be ing depressed through the medium of the arm E, secured to or integral with said frame, draws forward the bar F and swings back the arm N, thereby oscillating the shaft L and throwing back the dogs M out of engagement with the ratchet-teeth t of all the tablets. As soon as the key has reached its limit of depression and the catchy of the bar F has been released from the arm E, the tablet moved by said key is caught and held by the re engagement of its dog M with oneof the ratchet teeth i. In this instauce,where there are three keys arranged to each tablet, there are four notches forming the ratchet-teeth t. The low est of these, when engaged by its dog, as seen in Fig. 3, holds the tablet in its normal position of rest, with a blank or 0 exposed through the reading-openings. The operation ofany key of a set of the lowest value moves the tablet into such a position that the dog in its reengagement enters the first notch above and holds the tablet with the number corresponding to that key exposed. the next higher key of the same set so moves the tablet that the dog in re engaging enters the second notch above the lowest, and so on. It also results from this construction that whenever any key is operated the exposed tablet or tablets of previously-operated keys are, by the operation of the first-mentioned hey, immediately released and dropped back to their normal position above referred to.

It is of course obvious that there may be as many rocking tablets as there are keys, and it is likewise obvious that two or more keys may be connected to the same tablet instead of three keys, as I have shown and described. It is also evident that one of the reading-openings I have shown and described might be dispensed with, as well as that part of the tablet containing the numbers to be exposed through such opening.

That part of my invention above described which relates to the connection of a group of two or more keys to a single tablet is applicable to other forms of tablets than the one shown and described in this specification.

The construction of the arm 13, draw-bar F, and its latehj is shown and described in Pat ent No.132l,988,ot' July 14,1885. It will thus be seen that, as in previous machines of this class, the operation of any key to its farthest limit sounds the gong, operates the register ing mechanism, and exposes to view the numher on the tablet corresponding to the value of the key operated.

The next feature of my invention is shown more particularly in Fig. 3, where. each key is provided, just within the slotted front plate, 1?, of the machine, with a Hat guardplate, Q, extending above and below the key and of a The operation 0t be inserted to hook over the top of the vibrating frame, and, supposing the immediatelypreceding purchase had been of the same amount as the present one and a tablet therefore already exposed which corresponds to the amount of the present purchase, the operator, by pressing down the vibrating frame, might sound the gong without registering the amount of the purchase, and thus deceive the customer.

The next feature of my invention relates to the till and the mechanism for automatically removing the lid to expose the same whenever any key is operated, and is illustrated in Figs. 3 and 5, where the till R is an extension of the front of the case and is provided with a sliding lid, S, having at its rear, preferably near the middle and on its upper side, a stop, 70, with which a spring-latch, Z, pivoted, as at m, engagesto hold the lid closed over the'till. The latch is so constructed that a portion of it extends under the frame Gin such manner that the depression of the frame by the operation of the keys vibrates the latch, so as to release the stop 70. Springs T on each side,at-

, tached to the lid at its rear end and to stopsn at the back of the case or till-compartment, draw in the lid by their retraction whenever the stop It is released, and thus uncover the till; By drawing the lid out by means of a ring, 0, the stop It becomes automatically engaged with the latch Z to relock the 1id,as will be readily understood.

If desired, the construction in Fig. 5 may be employed, where the lid, instead of being drawn in by the springs, is thrown out to uncover the till whenever a key is operated.

The remaining feature of my invention is illustrated in Figs. 1, 3, and 6, where each key is provided (in this instance on its under side andjust outside of the front plate, P,) with a type, U, bearing a number corresponding to the value of the key. Just under these types and extending across the front of the machine and over a rubber bedstrip, V, is an inkingribbonflV, whose ends are wound upon spools secured within cases X at each side, as shown in Fig. 1. Each spool spindle is provided on the outside of the case with a ratchet, p, with which a pivoted dog, 9', engages to hold the ribbon taut and enableitto be shifted sidewise to expose fresh inking surface.

In addition to the dogs just referred to for holding the ribbon taut, any sort of weight devices may be applied to it above the rubber bed-strip V, as will be readily understood. The purpose of this mechanism is as follows: It is intended that each machine be provided with blocks of paper checks having printed thereon the proprietors name or any other desired matter, which checks are consecutively numbered, so that whenever the machine is to be operated to register and indicate a purchase the operator, tearing off the top one, inserts it beneath the ribbon W, under the key to be operated, in such manner that the depression of the key causes the number borne by said key to be printed upon the check. One of these checks is represented in Fig. 6, and they are intendedto be used in cases where a cashier other than the operator of the machine takes in the money. In such event the clerks, waiters, bartenders, or other operators have convenient access to the ma chine, and they print a check for each customer, while the same operation registers the amount. The customer gives this check to the cashier, together with the amount of money indicated by it. At the close of business for a day or other given period, when the cash is counted, the total amount received must correspond with the amount registered in the ma chine, and also, of course, with the amount of the checks received by the cashier.

The purpose of consecutively numbering the checks is to provide an additional safeguard against dishonesty on the part of the cashier by preventing his destroying any of the checks without detect-ion.

It is ofcourse apparent that the inking-ribbon might be dispensed with and the types be figured dies, in which event corresponding dies or matrices would be employed. in place of the rubber strip V in such manner as to stamp or emboss the number upon the checks.

1 am aware that it has heretofore been proposed to construct a registering and indicating machine embodying a series of keys of fixed values, a stationary dial having upon its face numbers corresponding to the numbers on the several keys, a movable disk or plate arranged over the face of the said numbered dial and having a reading-opening adapted to expose one number on the dial at a time, and connecting mechanism between the keys and the said movable disk, said elements being so arranged as that when a keywas struck the movable reading-plate would be rotated a distance sufficient to bring its opening opposite the number on the stationary dial corresponding to the number on the key so struck, and I therefore do not claim such construction to be of myinveution. It differs from my invention in that the number corresponding to the key struck is not always exposed at the same point, but at different points on the stationary dial, thereby rendering it very awkward to read, especially where several dials are employed to respectively indicate dollars and cents, whereas in my invention a stationary readingbpening is employed and the numbers to be exposed are brought in succession thereto, and where several letters are employed their reading-openings are enabled to be located immediately adjacent to and on a line with each other, so that the numbers on all the tablets may be read together at a glance.

Having thus fully described my invention, I claim- 1.
