T0 a/ZZ wiz/0m #may concern:

Be it known that I, HENRY GOLDMAN, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Registering Devices,of which the following is a specification.

My invention relates to registers, and has for its object to provide a new and improved register, of which the following is a description.

My invention is illustrated in the accompanying drawings, wherein- Figure l is a sectional view through a register embodying my invention. Fig. 2 is a section on line 2 2, Fig. l. Fig. 3 is a view of one of the numerahwheels of the register. Fig. e is a view of the periphery of the wheel shown in Fig. 3. Fig. 5 is a view of one of the carrying and resetting disks. Fig. 6 is a View of the inner face of the resetting-Wheel.

Like letters refer to like parts throughout the several figures.

This application is a division of application Serial No. 35,483, filed August l, 1900, and includes the registering deviceshown in said application in connection with a calculating mechanism.

It is of course evident that this register can be used in connection with many devices, and I have herein shown it in connection with a calculating-machine. I have not described in detail the calculating mechanism, as a description of such mechanism can be had by referring to my application hereinbefore described.

Referring now to the drawings,l have shown a series of numeral-wheels B, inclosed in a suitable casing A. Associated with these Wheels are suitable devices for actuating them. In the present case I have shown the chain C associated with each wheel, the chains being movable and being provided with projections which engage the teeth of the wheels. A spring-pressed stop-pawl A2 is associated with each numeral-wheel. These pawls prevent the backward movement of the numeral-wheels, and also insure their proper alinement. Said pawls are also preferably formed so as not to injure the plates or faces B. The numeral-wheels B are provided on their peripheries with a series of detachablyattached plates or faces B', separated by the teeth or projections B2. These faces are preferably made of material different from the wheels and may be attached in position in any desired manner. As herein shown, the wheels are provided with profiled recesses, into which are slipped the plates or faces BQ the projections or teeth B2 being provided with engaging parts which engage the plates to hold them rmlyin position. These plates may be made of any desired material-such, for example, as celluloid or the like-and the figures or characters on the numeral-wheels may be painted,enameled,or otherwise affixed thereon. The casing A is provided with an opening A', through which the figures on the numeral-wheels are read. The plates B may be completed before being attached to the wheels, and it will thus be seen can be readily slipped into place without injury to any of the parts. By this means the figures and the background upon which they are carried may be made of such diferent colors as to cause the figures to stand out clearly, so that they can be easily read. The plates on the different wheels may also be made of different colors, so as to form diiferent-colored backgrounds, for the purpose of distinguishing columns and denominations. Each numeral-wheel B is recessed on both sides. In one of these recesses is the ratchet-Wheel B3, which is connected to the wheel B, so as to rotate therewith, and in the other recess is located a spring pressed pawl B4, provided with a recessed tailpiec'e B5 for receiving the end of the spring B6, said spring being also connected with the numeral-wheel. Between the wheels B are located the carrying and resetting disks B7, connected with the shaft B8, so as to rotate therewith. These disks are provided with a depression B9 and a projection B10. Each pawl B4 is provided with a laterally-,projecting part B11, which extends into the recess of the opposed wheel B and which normally rides upon the edge of the disk B7. This disk is of such diameter that it holds the projecting part B11 out of contact with the teeth of the ratchet-wheel B3 on the adjacent numeral-wheel, but permits it to engage one tooth when it reachesV IOO the depression B9. It will thus be seen that when one of the numeral-wheels is given one complete rotation it will carry the adjacent wheel forward one tooth.` Each numeralwheel and each ratchet-wheel is provided with ten teeth, and hence this arrangement causes the numeral-wheels to be properly 10- tated. When the shaft B8 is rotated, the proj ections B19 of the carrying and resetting disks x engage the pawls B4, so as to move all of the numeral-Wheels back to the zero-point. The shaft Ba passes through the casing and is provided with some suitable controlling means. As herein shown, said shaft is'pror 5 vided with a resetting-wheel L, rigidly connected therewith. 'lhis resetting-wheel is l provided with some suitable holding mechanism for holding it against rotation while l the machine is being used. As herein shown, zo this resetting-wheel is provided with a movable piece L', preferably mounted upon the hub of the wheel L. This movable piece is, connected to the wheel by means of a screw or the like L2, which passes through an enlargedr opening L3 in the movable piece, so as to allow it a limited movement with relation to the wheel. A spring or the like L4 is connected with the wheel L and bears against" the movable piece L', so as to normally hold 3o it against the screw L2. Some suitable engaging device is connected with the casing A or some stationary part and is adapted to engage the movable piece L', so as to hold it against rotation. Any desired construction for this purpose may be used. As herein shown, a movable lock-pin L5 is located in the casing and is provided with a spring L9, which normally moves it outwardly. The movable piece L is provided with a suitable 4o opening L7 to receive the end of this lockpin, as shown in Fig. 6. Some suitable means is provided for disengaging the lock-pin from the movable piece L. Any suitable construction for this purpose may be used, and as herein shown I provide the resetting-wheel with a spring-actuated push-button L9,which has` a projecting part L9, adapted when the push-button is pressed to move the lock-pin out of engagement,las shown in Fig. 2. The

5o movable piece L is provided on each edge with beveled faces L19, which permits it to easily ride upon the end of the lock-pin L5 when rotated in either direction, so that said lock-pin may pass into the opening L9. This 5 5 lock-pin is provided with a suitable stop which limitsits outwardV movement, the parts being arranged so that it will be stopped before it projects far enough to engage the face of the resetting-wheel. By having a spring-actu- 6o ated-or elastic intermediate part between the resetting-wheel and the holding mechanism `a'p1edeten'iiilgrln pressure i s itppliedV thereto, Thes'pngmoving it back again when the pressure is released. This feature is of great importance in reducing thel pressure necessary to operate the numeral-wheels. If, for example, the numeral-wheels are moved to a position Where several of them show the Iigure 9 through the opening in the casing, a further manipulation of the machine necessitates the simultaneous movement of all of these wheels. Under these conditions the pressure applied to the chain must be sufficient to overcome the frictional resistance of all of the wheels. This often requires quite a good deal of force. If, however, the construction shown in Fig. 6 is used, the parts can be so (adjusted that the shaft B9 will itself move slightly when the pressure applied to the chain is somewhat greater than is necessary to rotate any one wheel, and thus all the wheels will be rotated simultaneously. This may therefore be accomplished with much less force than would be necessary to rotate all of said wheels independent of the shaft, and the strain upon the parts is thus greatly reduced. It will further be seen that by this means the chains can always be operated by a substantially uniform pressure,regardless of the number of nines to be carried over. The reason for this yielding or dipping of the shaft or arbor when a series of nines are being carried over iwill be made clear by referring to Fig. 1. It

`will be remembered that there is associated `with each wheel one of the disks B7 and that all of these disks are connected with the shaft `or arbor, so as to rotate therewith. When the numeral-Wheel is ina position to expose a 9 through the opening in the casing, the pawl B1 and its projecting part B11 are in the position shown in this figure,rthe projecting part B11 engaging one of the teeth 'on the ratchet-Wheel B3, connected with the associated numeral-wheel. It will be seen that the next move of the numeral-wheel carrying the pawl B4 will cause the projecting part B11 to ride along the depression B9 and up the ineline over the projection B19. This engagement produces considerable resistance to the movement of the parts, and-this resistance is reduced by the yielding of the shaft or arbor. -When two or more nines are to be carried over, the parts are so arranged that the friction at this point causes the arbor to vdip or yield, thus moving the disks and the projections B19 slightly and changing the incline, as `it were, so as to permit the projecting parts B11 to readily pass the projections B19. The pressure is then relieved and the arbor automatically returns to its normal condition. It will thus be seen that this construction produces a simultaneous yielding or dipping of all the disks and greatly reduces the internal 'friction and yet permits the arrangement of lthe parts in a small space, so as to produce a therefor www@ wheels isY r ove ashortsclistancienwllen.``
