TRANSFERRING AND RESETTING MECHANISM FOR CASH-REGlSTERS.

SPECIFICATION forming part of Letters Patent No. 570,196, dated October 27', 1896.

Application filed February 3, 1896. Serial No. 577,799. (No model.)

To all whom it may concern.-

Be it known that 1', FAYETTE BARNARD, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented a certain new and useful Improvement in Registering Devices, of which the following is a description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates more particularly to registering devices for cash-registering machines, and in the present instance is illustratedas applied to the register of the machine shown and described in Letters Patent of the United States No. 497,860, issued May 23, 1893, upon the application of Thomas Carney.

The first feature of my invention relates to the means for resetting the registering-wheels or returning them to zero or initial position at the end of a days business or such other time as the reading is taken from the wheels; and it consists in the provision of an automatic stop which arrests the parts at the end of their resetting movement and prevents them being turned beyond initial position.

The second feature of my invention relates to the transfer devices between the several wheels; andit consistsin the provision of look ing devices controlled by the cams which actuate the transfer-pawls, whereby such pawls are normally locked from movement but are automatically released by the cams preparatory to the actuation of the pawls by the cams.

In the accompanying drawings, Figure 1 represents a perspective view of the register of one of the common forms of machines built under the patent before mentioned with my improvement applied to it; Fig. 2, a vertical section thereof; Fig. 3, an elevation of the left-hand end of the samethe end opposite that shown in Fig. 1; Fig. 4, a detail view of some of the parts shown in Fig. 3, but in a different position; and Fig. 5, a view corresponding to Fig. 4, with the parts in still another position.

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

The registering-wheels A are mounted upon a shaft I3, journaled in the upper ends of the opposite side arms of a frame O, which frame is pivotally supported at D in the framework of the machine in which the register is located. Secured upon the right-hand end of the frame C is a horseshoe-shaped plate E, whose rearwardly-extending arms carry at their ends friction-rollers F, which cooperate with rotary cams in the machine referred to, by which the frame O is rocked back and forth at each operation of the machine to gear and ungear the pinions G of the registering-wheels with the oscillating actuatingsegment-s thereof, as fully described in the patent referred to. The shaft B, upon which the registering-wheels A are mounted, has fast upon its right-hand end a beveled pinion II, which meshes with a second smaller beveled pinion l, which is fast upon the lower end of a vertical shaft J, journaled in a supporting-bracket K and provided at its upper end with a thumb-piece L, by which it may be turned to rotate the shaft-'13. Interposed between the shaft B and the several registering-wheels are suitable devices for causing the" shaft when turned in one direction to pick up the wheels at the different points at which they may be standing and carry them to initial position with it. In the present instance such means consists of pawls M, pivoted to the sides of the respective wheels, Fig. 3, and cooperating with a longitudinal notch or groove in the shaft B in the wellknown manner.

Fast upon the left-hand end of the shaft B, Fig. 3, is a disk N, having in its periphery a single notch with which cooperates the rearwardly-extended end 0 of one of the supporting side arms of a frame P, composed of its two side arms and an integral cross bar or plate connecting their front ends. The frame P is pivotallysupported by its side arms upon a rod Q, mounted in the frame C, while a spring R, interposed between the frame C and the under side of the cross-bar of the frame P, Fig. 3, presses the frame P upward and the rear end of its arm 0 downward, maintaining the latter in engagement with the periphery of the disk N. In the normal position of the parts the rear end of the arm fits in the notch in the disk N, as seen in Fig.

but when the shaft B is turned in the manner heretofore described to reset the registering-wheels the rear end of the arm 0 is lifted as the notch in the disk N is carried from under it, and the frame I forced downward against the resistance of the spring R. After the shaft 13 has been turned far enough to carry the notch in the disk N from under the arm 0 the latter will ride upon the periphery of the disk during the further movement of the latter until the notch is again brought .beneath the end of the arm, whereupon the latter will spring into the notch again and the parts come to rest in normal position, as seen in Fig. 3.

The construction and operation of the parts above set forth are substantially the same as those found in the Carney machine, which has been referred to, and were old at the date of my invention, the first feature of which, as before stated, consists in the provision of means for arresting the parts at the end of the resetting revolution of the shaft 13 and preventing them being carried beyond normal position.

It will be understood that with nothing more than the parts above described it would be possible to turn the shaft B right on beyond initial position without stopping at that point, in which event it would be necessary to give the parts a further revolution in order to bring them to initial position.

111 the absence of my invention the reengagement of the arm 0 with the notch in the disk N, as well as observation of the position of the numbers upon the registering-wheels, may be relied upon to determine when the parts have reached initial position, but I have found it advantageous to provide apositive stop for arresting them at that point and preventing the possibility of movement beyond it, so that no care in watching the numbers upon the wheels or in noticing the reengagement of the arm 0 with the notch in the disk N is required. To this end I mount upon the left-hand end of the rod Q, which supports the frame P, Fig. 3, a rearwardly-extending locking-arm S. This arm is loose upon the end of the fixed rod Q, but is provided with a stud T, which projects over the edge of a second arm U, formed integral with the frame F and extending downwardly and rearwardly therefrom for a purpose entirely independent of myinvention and which need not be here described. So far as my invention is concerned the arm U could be dispensed with or be cut off immediatelyin rear of the stud T, it being only necessary that the locking-arm S be connected in some manner to the arm 0, so as to be moved upward by said arm and permit said arm to move downward independently of it. A spring V,

. coiled around the rod Q, bears at its rear end against the stud T on the arm S and at its forward end upon the side arm of the frame P and serves to press the arm S downward and yieldingly hold it in normal position,with

the stud T resting against the upper edge of the arm U. Projecting from the side of the disk N, slightly below and in rear of the notch in the disk, is a stud \V.

N ow, under the construction and arrangement of parts above described, when the shaft 13 and disk l are turned to reset the registering-wheels and the notch in the disk is carried from under the end of the arm 0 and the latter caused to ride upon the periphery of the disk, as in Fig. 4;, it will be seen that the locking-arm S is lifted into such position that its rear end stands directly in the path of the stud \V upon the disk N. The result is that as the parts reach or slightly pass initial. position the stud \V will abut against the rear end of the arm S, the latter being slightly rounded out to fit the surface of the stud. At the same instant that "the stud engages the end of the arm S and the further movement of the parts is thereby arrested the upper edge of the notch in the disk N will clear the rear end of the arm 0 and the lattu' will spring downward against the lower radial wall of the notch, with the result that the parts will be arrested in the position shown in Fig. 5. The engagement of the stud \V with the end of the arm in will prevent the latter moving downward with the arm O,with the result that the rear end of said arm S will be held up in the position shown in Fig. 5 against the pressure of its spring 'V, which tends to throw it downward. The pressure of the rear end of the arm 0 upon the lower wall of the notch in the disk, under the action of the spring R, will tend to force the disk slightly backward from the position shown in Fig. 5 and permit the end of the arm to fully engage the notch, as seen in Fig.

As soon as the pressure upon the thumbpiece L, by which the parts have been turned forward, is released, the rear end of the arm 0 will be forced downward to the position shown in Fig. by the action of the spring It upon the frame I. This will move the stud \Y slightly rearward and disengage it from the end of the arm S and permit the spring V to throw the latter downward to normal position.

From the foregoing description it will be understood that no matter how rapidly or violently the shaft 1; is turned in resetting the registering-wheels the parts will be positively arrested when they reach normal position, so that no further movement is possible without first releasing the pressure upon the thumb-piece by which the shaft has been turned. Any excessive movement of the parts through mistake or accident is therefore rendered impossible.

The second feature of my invention, as has been stated, relates to means for locking the transfer-pawls in normal position and preventing movement of them except by their actuating-cams. In the register shown in. Fig. 1 the transfers between the first and sec 0nd and second and third wheels are effected by means of pawls X X, which cooperate with ratchets upon the hubs of the second and third wheels, said ratchets being hidden in Fig. 1 by the first and second wheels, but corresponding to the ratchet of the first wheel shown in Fig. 1. (See Fig. 2.) The transfers between the third and fourth and the higher wheels in the series are effected, in the present instance, by transfer devices of familiar construction which do not employ any actuating-pawls and to which my invention has no application and which need not be here described.

The transfer-pawls X X for the second and third wheels are pivoted in and carried by the upper ends of long curved levers Y Y, which are fulcrumed at D in the frame 0 and extend horizontally rearward from their fulcrum's and carry upon their rear ends friction-rollers Z Z, with which cooperate, respectively, cams A A upon a rotary shaft 13, Fig. 2. Under this construction and arrangement of the parts at each revolution of the shaft 13 the cam A will engage the roller Z upon the rear end of the lever Y and rock said lever and throw the pawl X rearward, while the cam A will immediately thereafter engage the roller Z of the lever Y and in like manner throw the pawl X rearward. The two pawls are normally held up in inoperative position by latches X a11dX ,wl1icl1 latches cooperate with projections Y and Y upon the hubs of the first and second registeringwheels, by which at each revolution of either of those wheels the latch for the pawl of the next higher wheels is tripped and the pawl set to effect a transfer at its next rearward movement in. the well-known manner.

The construction and operation of the transfer devices as above described are substantially thesame as in the Carney machine referred to. Under such construction and arrangement it will be seen that there is nothing to prevent the levers Y and Y being rocked at anytime by any force applied either to them or to the transfer-pawls, so that should said levers be moved at any time, by accident or design, otherwise than by the cams upon the shaft 13 improper transfers might be effected and the registration falsified. To prevent this,I have provided a locking device for each of the pawl-levers, which locking device normally locks said lever from move ment by force applied to it in any manner and permits movement of it only after it has been unlocked or released by first moving the locking device, and this locking device stands in the path of the cam cooperating with such lever, so that it is struck by the cam and caused to release the lever immediately before the cam engages the lever to move the latter. As seen in Fig. 1, the lower end of the frame 0 is provided with two rearwardly extending arms 0 0 upon opposite sides of the rear ends of the pawl-levers Y and Y. Hung uponarod D, supported in these arms and extending across the upper sides of the levers Y Y, are two locking-plates E E one beside each of the lovers Y Y. Each of these plates has projecting from its side a stud F, which fits in a notch in the edge of the adjacent lever, while springs G, coiled around the hubs of the plates E E and pressing upward at their rear ends against the lower edges of said plates, yieldingly maintain the studs F in engagement with the notches in the levers.

Under the construction and arrangement above described if it be attempted to press the rear end of one of the levers clownward the direction of the pressure thereby exerted upon the stud F of the adjacent locking-plate is such, in relation to the pivotal point of such plate, that the stud will simply bind in the notch of the lever and the plate will not yield, but, on the con trary,will firmly lock the rear end of the lever from downward movement. If, however, the locking-plate is slightly depressed and its stud F disengaged from the notch in the lever, the rear end of the latter may be freely depressed, the stud, as the lower edge of the lever contacts with it, slipping along the under edge of the lever in front of the notch in the latter. Now in the revolution of the shaft B the cam A will strike the upper rear corner of the plate E and depress the latter, and thereby release the lever Y before it contacts with the roller Z upon the .rear end of the lever and rocks the latter to throw its pawl X rearward, and likewise the cam A will contact with the plate E and release the lever Y before it reaches the roller Z upon the rear end of said lever.

From the foregoing description it will be seen that the pawl-levers and pawls are nor mally locked and cannot be moved by any force applied to them without first depressing the locking-plates E E and disengaging the studs F from the notches in the under edges of the levers, and that said plates are engaged by the cams upon the rotary shaft and the levers thereby automatically released preparatory to the engagement of the cams with the levers for actuating the pawls.

So far as I am aware I am the first in the art to provide a locking device of any sort for the transfer-pawl of a register, which device normally locks said pawl from movement and cooperates with the actuating device of such pawl to automatically release the pawl preparatory to its movement by the actuating device.

Having thus fully described my invention, I claim 1.
