SPECIFICATION forming part of Letters Patent; No. 538,410, dated April 30, 1 89 5.

Application tiled November l, 1894. Serial No. 527,638. (N0 model.)

T0 all whom t may concern:

Be it known that I, JOSEPH P. CLEAL, 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 Registers, 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 that style of registers or counters in which the numbered registering wheels are mounted side by side upon one shaft, and in which the complete rotation of any one wheel is caused to advance the next higher wheel in the series one number by means of a train of transfer gears mounted side by side upon an axis parallel with the axis of the registering wheels and co-operating with gears and projections upon the respective wheels. Each registering wheel has fast upon it a gear meshing with one of the transfer gears and carries a tooth or projection which at each complete rotation of the wheel engages the transfer gear which meshes with the gear of the next higher registering wheel, so that at ea ci rotation of the lower wheel the engagement of its single tooth or projection with said transfer gear will turn it and cause the next higher wheel to be advanced one number. In addition tothe transfer gears there are usually mounted upon the same axis, one fast upon the side of each gear, a series of notched locking disks whose notches fit snugly against either the peripheries of the registering wheels or against co-operating circular locking disks fastnpon their hubs, the purpose of which is to hold the transfer gears from movement except when turned by the tooth or projection on one of the registering wheels to effect the transfers. Now, in such registers, when the registering Wheels are toY be returned to zero or initial position it is necessary to disengage the two sets of locking disks from each other, to permit the registering wheels to turn. To this end the train of registering wheels and the train 0f transfer gears are usually mounted in separate frames, one movable relatively to the other, so that the two sets of devices may be thrown ont of operative relation when the Wheels are to be re-set lto initial position and back into such relation after they have been re-set. Heretofore it has been necessary to separate the two sets of wheels by one operation, and then reset the registering wheels by another operation,and, in some instances, to then throwthe two sets of wheels into cooperative relation again by a third operation.

My invention consists in the provision of means for making the act of separation and re-engagement substantially automatic, or incidental to the re-setting operation, so that it is only necessary to grasp the handle of the re-setting shaft upon which the registering wheels are mounted and give it a rotation in order to separate the transfer gears from the wheels, re-set the latter to initial position, and permit the re-engagement of the gears and locking disks.

The train of transfer gears maybe separated from the train of register wheels so far as to disengage both the locking disks and the gears of the respective trains, in which event the transfer gears and their locking disks will remain stationary while the registering wheels are re-set to zero; or the two trains may be separated far enough to disengage two sets of locking disks, without entirely disengaging the two setsof gears,in which event the transfer gears and theirlocking disks will be turned with the registering wheels as the latter are re-set.

In the accompanying drawings I have illustrated my invention as applied to a well known style of cash register, such as that described in Patent No. 464,294, to Cook, dated December 1,1891, and the adjustment cf the parts is such that in this instance the registering wheels and transfer gears are separated at each resetting operation only far enough to disengage the two sets of locking disks, although Without any material variation the adjustment might be made such that both the locking disks and gears would be entirely disengaged from each other.

In said drawings, Figure l is atop plan view of a set of registering-wheels and transfer devices and portions of the supporting side frames between which they are mounted; Eig. 2, an elevation of the right side of the same, being a vertical section immediately to the left of the right-hand side frame on the lOO line 2 2 of Fig. l; Fig. 3, a vertical section on the line 3 3 of Fig. 1; Fig. 8, a detail view of a registering-Wheel and its locking devices; Fig. 4, an elevation of the parts on the outer side of the left-hand side frame; Fig. 5, a vertical section through the train of registering-wheels longitudinally of the shaft upon which they are mounted; Fig. 6, an elevation of the left-hand side of the shifter-plate with some of the cooperating parts in section, and Fig. 7 a detail plan view showing the cams for operating the shifter.

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

The rotary re-setting shaft A is passed through and mounted in the side frames B B and has fastened upon its right hand end a milled disk by which it may be turned. The registering wheels C are arranged side by side upon this shaft. Each wheel except the left hand one has fast upon its left side a singletoothed disk D, and each wheel except the right hand one has fast upon its right side a gear E.

Mounted upon a rock shaft F journaled at its opposite ends in the side frames B B are the transfer gears which co-operate with the disks D and gears E of the wheels C. Each transfer' gear consists of two halves G H, rigidly secured to or formed integral with each other the former being a plain gear meshing with the gear E of the next higher wheel C, and the latter being a mutilated gear, with every third tooth partly or wholly out away, as seen in Fig. 3. These mutilated gears cooperate with the disks D of the wheels C and serve both as locking disks and as part of the transfer gears.

When the parts are in normal position the teeth upon the opposite sides of the spaces formed by the mutilated or cut-away teeth tit snugly against the peripheries of the disks D and thereby lock the transfer gears from turning, Fig. 3f. The out-away spaces leave the remaining full teeth in pairs, and at each rotation of the disk D its single tooth D will enter between the two teeth of the upper pair which at the time are resting upon the disk and will turn the gear forward, the two notches or depressions at the opposite sides of the base of the tooth D', which are entered by the respective teeth of the pair, permitting the gear to turn, Fig. 3. The gear H of course carries the gear G with it, and as the latter meshes with the gear E of the neXt higher registering wheel C the latter will therefore be advanced the same distance as the gearsin this instance a tenth of a rotation.

The transfer gears are not mounted directly upon the rock shaft F, but upon eccentric sleeves or bearings I fast thereon. When therefore the shaft- Fis rocked forward the gears will be moved away from the registering wheels, either far enough to entirely separate the gears G from the gears E and the mutilated gears H from the disks D, or at least to separate the latter, so that the wheels C may be turned freely, either with or without the gears G H being turned with them. In the present instance the adjustment of the parts is such that, by the means hereinafter described, the gears H are separated from the disks D, while the gears G remain slightly in mesh with the gears E, so that the turning of the wheels C turns the gears G H as weil..

The rock shaft F has fast upon its left hand end, outside the frame B, an upwardly extending arm J, Fig. 4, to which is pivoted the front end of a plate K which is slotted at its rear end and embraces the shaft A. The latter has fast upon it a disk Lhaving in its periphery a notch M in which fits a roller N on a stud upon the side of the plate K. A coiled spring O connected to the lowerend of aseoond arm P fast upon and dependingfrom the rock shaft F yieldingly holds the parts in normal position, with the transfer gears in cooperative relation with the registering wheels and the roller N fitting in thenotch in the disk L. Vhen the shaftA is turned and the roller thereby forced out of the notch in the disk the shaft F will be rocked and the transfer gears thrown forward and the registering wheels C permitted to be re-set. In this man ner the mere turning of the shaft A to re-set the registering wheels serves to disengage the the transfer gears and permit such re-setting.

Any of the usual or suitable devices may be employed for causing the shaft in its rotation to pick up the registering wheels and carry them with it, such as a longitudinal notch or groove in the shaft and spring pawls on the wheels co-operating with it; butin the present instance I have provided novel means for the purpose. As seen in Fig. 5 the wheels C are not mounted directly upon the shaft A, but upon an interposed sleeve Q fast upon the shaft. This sleeve has in it a longitudinal groove in which fits a slide R having a series of lugs S upon its outer side, one of which lugs [its within an annular' recess in each gear E, the latter being fastened upon the right hand sides of the wheels C. The wheels C have lugs T projecting into these recesses and adapted to co-operate with the lugs upon the slide. When the latter is in its right hand position its lugs stand to the right of the vertical plane of the lugs T, so that the wheels C are free to turn upon the sleeve. Then the slide is moved to the left its lugs are brought into the planes of the lugs T, and when the shaft A and sleeve Q, are then turned the lugs S will engage the lugs T and pick up the registering wheels wherever they may have been left and carry them around with it to initial position.

Inasmuch as the slide R has to be moved to the left each time, to bring the lugs S into position to engage the lugs T of the wheels I have 'provided automatic means for so shifting the slide at the beginning of movement of the resetting shaft A, which means may be now described.

Fitting over the right hand end of the sleeve :Semic Q is the rear end of a spring arm or plate U secured at its front end to the right hand side of frame B. The right hand end of the slide R also passes through the opening in the plate U and is connected to it by its righthand lug S and a projection or pin upon the slide upon the other side of the plate, the latter tting between the two, so that the rear end of the plate moves laterally with the slide. Secured upon the left hand side of this plate about midway of its length is a block V having a forwardly projecting beveled lug W which stands in the path of a cam X upon the rear end of an arm Y fast upon the rock shaft F, Fig. 7. Vhen said shaft is rocked by the first movement of the re-setting shaft A the cam X is thrown upward and forces the plate U to the left and carries the slide R into position for its lugs to co-operate with those upon the registering wheels. When the rotation of the shaft A is completed and the shaft F rocked back to initial position by its spring the cam X will be thrown downward again and the plate U will spring to the right and return the slide to normal position. The pendent arm P upon the left hand end of the rock shaft F, to which the spring O is connected, Fig. 4, also serves as a locking device to automatically lock the operating keys and handle of the machine while the registering wheels are being reset to Zero.

As before stated the register of Figs. l to 7 is shown as applied to the machine of the Cook Patent No. 464,294. Upon reference to that patent it will be seen that the operating keys in each row co-operate with a curved detent plate which detains them in set position while the operating handle is being turned to effect the registration and indication. It will also be seen that the operating handle is normally locked from movement and that it is unlocked, to permit operation of it, by the movement of any one of the detent plates incident to pressing in or setting a key. Now, the pendent arm P above referred to serves to lock the detent plate B from movement while the registering wheels are being re-set, and consequently locks the keys and prevents release of the handle.

In Figs. 2, 3 and 4 are illustrated such parts of the above mentioned devices as are necessary to an understanding of the locking operation of t-he arm P. A few of the Lipper keys A of the left hand row of the machine are shown in said figures. Likewise the upper end of the detent plate B with which they co-operate in the manner above described, and the recessed arm C fast upon the rock-shaft Dgaud with the front end of which the lug E upon the end of the detent plate co-operates. When the plate is forced rearward by pressing in a key the lug E contacts with the beveled under side of the upper jaw F of the recess in the front end of the arm C and lifts the latter and rocks the shaft D2, causing the latter to move an obstruction out of the path of the operating handle at the other end of the machine, as may be readily understood without further illustration here, and as is fully shown and described in the patentaforesaid. Now, when the rock-shaft F is rocked forward by the turning of the shaft Ato re-set the registering wheels in the manner heretofore described, the lower end of the arm P is thrown rearward immediately over the front end of the jaw F of the arm C so that so long as the arm P remains in such position the front end of the arm C cannot move upward. Consequently the contact of the lug E with the jaw F of the arm C will prevent any upward movement of the detent plate B and prevent operation of the keys and unlocking of the handle. In this manner the entire machine will be locked at the first 11e-setting movement of the shaft A and remain locked until said shaft has been given a complete rotation and the registering wheels brought to initial position.

As previously stated, it has heretofore been necessary in the use of registers of this class to disengage the transfer .gears and locking disks from the registering wheels by one operation and to re-set the wheels by another. So far as I am aware I am the first in the art to combine with the re-setting means of such a register any sort of means for automatically separating the registering wheels and transfer devices by the act of re-setting the wheels, and my invention, in its broadest sense, is of corresponding scope.

Having thus fully described my invention, I claiml.
