EDIVARD F. ROBERTS, OF COLUMBUS, OHIO, ASSIGNOR TO THE ROBERTS MANUFACTURING COMPANY, OF SAME PLACE.

CASH-REGISTER.

SPECIFICATION forming part of Letters Patent No. 487,683, dated December 6, 1892.

Application filed May 25, 1892. Serial No. 434,282. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD F. ROBERTS, of Columbus, Franklin county, Ohio, have invented certain new and useful Improvements in Cash-Registers, (Case 13,) of which the following is a specification.

United States Letters Patent No, 483,946, granted to me October 4, 1892, for cash-registers, on my application filed April 9, 1892, Serial No. 428,523, sets forth a cash-register provided with count-wheels and finger-keys. There was a lowest-value key and a group of keys to which it belonged, the keys increasing in value by the unit represented by that lowest-value key, and that unit was the unit of count of the count-wheel belonging to the group. The count-wheel bore successive series of readings corresponding withthe keys of the group, with a zero between each series. Another count-wheeland group of keys pertained to higher values, the unit of the second group being equal to the highest and lowest value of the group below, when the lower count-wheel exceeded its maximum of reading value it went to zero, and proper mechanism transferred one of the high units to the higher couut-wheel, and this system was carried forward, a third count-wheel taking its unit bytransfer from the second group. All the keys of a group actuated a dragro'cker uniformly for each key-stroke. A count-rocker carried a pawl engaging the count-wheel and doing the counting, the degree of count corresponding with the number of teeth advance made by the count-pawl. The drag-rocker pulled the count-rocker and tended to pull it the full stroke of the'dragrocker; but release took place, as admeasured by the keys, and the count-pawl therefore made only the stroke pertinent to a given key, while the d rag-rocker went on and made fullstroke. The count-wheel atthe end of its forward stroke became locked.

My present invention pertains to improvements in registers of the class set forth in my earlier patent referred to. I improve the connections between the keys and the dragrocker, and also improve the connections between the drag-rockers and the count-rockers. I provide an improved bell-ringing device and improved tablet-holder and improved drawer-locking mechanism. I improve the mechanism of transfer from a lower countwheel to a higher one. I furthermore improve cash-registers by providing that they shall count grand totals as usual, grand totals of all the amounts fingered into the register, and in addition provide for showing upon ad ditional count-wheels what values pertain to several departments of the business. Thus, for instance, assume the register in use in a drugstore and that it is desirable to know the total amount of sales, the amount due to cigars, the amount due to toilet articles, and the amount due to drugs or any such similar division.

As many of the details of the present register follow closely after those set forth in my earlier patent referred to, reference is hereby.

made to that earlier patent fora clear understanding of the general principles of construction and of the working of the various details.

My presentinvention will be readily understood from the following description, taken in connection with the accompanying drawings, in which- Figure 1 is a vertical transverse section of a cash-register exemplifying my present invention; Fig. 2, a similar view of the drag and count rockers showing the parts at the time a key has been depressed and is ready for return; Fig. 3, an end elevation of the main parts of the machine, showing the bell-ringing and target-releasing devices; and Fig. 4 a plan of the register minus the ease, &c., the tabletrods appearing in horizontal section.

In exemplifying my present invention I show but two count-wheels with their rockers and groups of keys, and I show the register arranged for keeping tally for three separate departments.

q, a group of finger-keys representing, re

55st AVAILABLE com spectively, twenty-five cents and multiples thereof, this group of keys operating upon the count-wheel p precisely as group E operates upon count-wheel J, the group q and count-wheel 19 being provided, also, with a count-rocker, drag-rocker, &c.; r, the transfer-pawl attached to the transfer-rocker and engaging the higher count-whee p; s, apawl attached to the rocker Y for operating the transfer-rocker j when rocker Y moves upwardly under the influence of any key, a shoulder on this pawl engaging under point 0 of the transfer-rocker; t, a cam on pawl s, causing the pawl to release from the transferrocker when the upward movement of the pawl has moved the transfenrocker a distance equal to one tooth of the count-wheel which it moves, it being understood that the upward movement of this pawl will not move the transfer-rocker at all so long as the transfer-rocker is locked by the hook Z in its forward position of stroke, which position is the normal position of the transfer-rocker; u, a department counting wheel to record the amount of sales pertinent to a certain departmentsay, cigars-it being the duty of this wheel to make note of all cigar-sales counted into the register-by means of any of the keys E, this department count-wheel containing a series of graduations increasing in value by five cents as a unit, represented by one tooth of the wheel, this department-wheel being hereinafter termed the low'group cigar-wheel; o, a precisely-similar department count-wheel pertaining to, say, toilet articles, and hereinafter termed the lowgroup toilet-wheel; w, a stop-pawl for each of the departmentwheels; and here it is to be explained that the department-wheels u and o are duplicated for the higher group of keys, as will be referredto later; 01;, a pawl-carrying rocker at the department-wheels u and '0, a preciselysimilar rocker being provided, also, at the duplication of these wheels; y, a link connecting the appropriate one of these rockers m with the count-rocker N, a similar link connecting the other one of the rockers a: with the count-rocker pertaining to the higher group q of keys; 2, a pair of pawls carried by each of the carriers 00, there thus being an independent pawl for each of the department-wheels, these pawls being normally out of engagement with their wheels; a, an independent pawl -guide under each of the pawls 5; Z), a department-key pertinent to the cigar-department in the exemplification; c, a bar carried by this key and extending under the department count-wheels; d, prongs projecting from this bar up under each of the pawl-guides a, which is under a cigarwheel, it being understood that there are two cigar-wheels, one pertinent to the lower group of keys and the other pertinent to the higher group, so that if this cigar-key be operated it will lift the pawl-guides under the two cigarwheels and bring their pawls into engagement; e, a department-key pertinent to the toiletwheels; f, a prong-bar carried by this key, this bar carrying prongs located under the pawl-guides of the toilet-wheels; g, the highh' are precisely like the wheels u and 0, ex-

cept that their unit of graduation will be twenty-five cents instead of five cents; j, a spring-hook adapted to engage under the end of any department-key that is put into operative position, and thus serve in supporting thatkey and supporting the pawl-guides a pertinent to that key in such position that the pawls above them will be held in engagement with their wheels; k, a trip piece attached to the till and adapted, when the till is pushed in, to move the hookj out of engagement with any department-key which it may be holding up, thus permitting the key to come down again; Z, a spring tending to draw the rocker Y down to normal position; m, the shaft on which the department-wheels are mounted, the department-wheels being shown as disposed to the rear of the main portions of the register; a, the spring which holds the friction-wing X into engagement with the tablet-stems; 0',the cam upon the bar g, which gives it its lateral motion as it moves endwise, the cam being a zigzag slot in the bar, engaging a pin in the framing, whereby endwise motion of the bar results in transverse motion at its upper end; 19', the prong of this bar which operates the bell-lever as the bar rises; q, a fly upon the bar g to engage arm Z of the friction-wing as the bar 9 rises and to yield and clear that arm as the bar descends; r, a similar fiy upon the bell-lever to operate in conjunction with the prong p.

The general plan of counting, transferring, &c., is the same as in my earlier patent, hereinbefore referred to. WVhen one of the fingerkeys E is depressed,its armV pulls the dragrocker back. The first movement of the drag rocker clears it from dog T and allows the dog to lock the count-pawl to its wheel. Further movement of the drag-rocker causes the drag-pawl O to engage the pawl-carrier P, and then the drag-rocker pulls the count-pawl positively forward to make the count. This movement of the count-rocker continues until the prong H, which has risen, engages a count-ward and prevents further advance of the count-rocker. Then the cam or incline on the drag-pawl engages the pin on the countrocker and the drag-pawl is lifted from the pawl-carrier P and the drag-rocker goes on and completes its stroke, leaving the countrocker in whatever position the count may have called for. On the return of the dragrocker the dog T will be released from the count-pawl and all the parts will go back to normal position. Normally the stroke of pawl 8 gives no motion to the transfer-rocker j, that rocker being retained at its forward position of stroke by the hook Z. lVhen a pin m of count-wheelJ releases the hook, the transferpawl instantly moves to extreme back posi- Best AvAuAeLE'ooPr tion. Then when any key of the register, regardless of group, is operated the rising of pawl s will advance the transfer-rocker and cause pawl r to advance the higher-value couut-wh eel one tooth, and the transfer-rocker will again be locked in forward position and remain so till the next pin releases it. The transfer-count will always be given before arms V produce any counting motion of the dragrocker. Each key raises its appropriate target, as usual, and when raised the target will beheld up by the friction-wing. At the next actuation of any key the first rising of a key, acting through rocker Y and bar g, releases the friction-wing and permits the dropping of any target or targets which may be up. The operation of any key rings the bell and also releases till-pawlfand allows the till to spring open. 1

It is obvious that department-rocker as, pertinent to low-group department-wheels, will have movement corresponding with the movement of low-group count-rocker N; but that movement of the department-rocker will have no effect on department count-wheels so long as pawls z are free. If a cigar-sale is made, the cigar-key is first depressed. This lifts the cigar-pawls into action. Assn me the sale to be a fifteen-cent one. The fifteen-cent key being depressed counts fifteen cents upon countwheel J, and simultaneously fifteen cents is counted on cigar-wheel u. Had the sale been a fifty-cent one the fifty-cent key would have caused the main count to be made on countwheel p and the department count to be made on cigar-wheel g. Vhen the till is pushed in after the counting, such department key as is in action will be released and go to normal position. Thus the main count-wheels of the register receive the counting of total sales and the department-wheels show the sales for the several departments. There may be as many department-wheels as desired and a key for each department. In taking the readings of the department-wheels it is necessary of course to add together the readings of the several wheels pertaining to a given department. The department counting arrangements should be made extensive enough to carry the full days sales of the department-a mere question of large wheels or of transfersas is usual in register-wheels.

While in the exemplification I show department-wheels for but two departments, it will be obvious that three departments are provided for. Thus having in the business three departmentsviz., cigars, toilet articles, and drngsthe main count-wheels carry the total of everything and the department-wheels the sales pertinent to cigars and toilet articles. Therefore if the sum of cigar and toilet sales be subtracted from the total the remainder will be due to drugs. Any number of departments may thus be provided for by means of special department keys and Wheels for all the departments but one. Credit-sales may be considered as a department, in which case the usual charge-ticketshould go into the drawer when a credit-sale is made or else the proper charge should be made on the books. In such'case the main portions of the register show total sales, including cash and credit, and the credit-department wheel or wheels will show the amount of credit-sales for which the drawer need not account in cash.
