ACTUATING DEVICE FOR CASH-REGISTERS.

SPECIFICATION forming part of Letters Patent No. 477,883, dated June 28, 1892. Application filed September 21, 1891. Serial No. 406,289. (No model.)

To all whom it may concern:

Be it known that I, GEORGE BOEMERMANN, a citizen of the United States, and a resident of Brooklyn, Kings county,New York, have invented certain Improvements in Cash Registers and Indicators, of which the following is a specification.

My invention relates to an improvement on the cash register and indicator described in the Letters Patent No. 456,133, granted to me July 21, 1891, which patent may be referred to for a full understanding of those portions of the register and indicator which form no part of my present invention. 111 the register described in my said patent, No. 456,133, there is a series of pulls, each of which corresponds to asum of money, as five cents, ten cents, fifteen cents, &c., and when the sales man receives a sum-as ten cents, for example-he draws out the pull corresponding to or marked 10 and pushes it in again,wl1en this sum 10 will be properly registered on an adding mechanism in the apparatus with which this pull is mechanically connected or which is operated by the movement of the pull. In the register described in my said patent the intermediate mechanism whereby the drawing out of a pull rotates the wheels of the adding mechanism to an extent corresponding exactly to the denomination of the pull consists of a series of toes fixed on a rock-shaft extending transversely over the series of pulls, one toe being over each pull, and on each pull is an upright which, when the pull is drawn out, strikes this toe and rocks the rock-shaft to an extent due to the denomination of the pull. The rockshaft is connected by intermediate mechanism with the wheels of the adding mechanism in such a manner that its motion is imparted thereto. The toes are set at different angles on the rock-shaft in such a manner that, although all the pulls are moved to the same extent, they do not impart the same amount of rocking movement to the rock-shaft. For example, pull 10 will impart to said shaft twice as much movement as pull 5, and pull 15 will impart to it three times as much movement as pull 5. This description I have deemed necessary to a clear understanding of my present invention, which has for its object a novel intermediate mechanism between the pulls and the adding mechanism,whoroby the former actuate the latter to an extent proportionate to their respective denominations.

This invention will be fully described hereinafter and its novel features carefully dcfined in the claims.

In the drawings serving to illustrate my invention, Figure 1 is a sectional side elevation of that portion of a cash register and indicator which embodies my improvements, the plane of the section being indicated by the broken line was in Figs. 2 and 3; and Fig. 1 is a View like Fig. 1, but showing a pull drawn out. This view merely illustrates the operation of the parts seen in Fig. 2. Fig. 2 is a sectional front elevation, the plane of the section being indicated by the broken line y y in Fig. 1. Fig. 3 is a sectional plan, the plane of the section being indicated by the broken line .2 .2 in Fig. 1.

A represents the casing, which maybe constructed in the usual manner, and 1 represents the sliding pulls mounted in said frame and operating in the ordinary way.

2 represents the wheels of the adding mechanism, mounted on a shaft 3 and driven through the medium of pinions d on a shaft 5. One pinion 6 on the shaft 5 gears with a wheel 7, mounted 011 a stud on the frame.

All of the above mechanism is substantially the same as that shownin my patent, No. 345,692.

I willnow describe the novel mechanism I employ for driving the adding mechanism through the medium of the pulls 1.

S is a shaft mounted in suitable hearings in the frame and extending transversely over the pulls. On this shaft is fixed a toothed wheel 9, which gears with the wheel 7. Thus intermittent rotation of the shaft 8 in one direction will impart a corresponding motion to the addingwheels. The pulls impart the required intermittent rotation to the shaft 8 through the medium of mechanism which I will now describe: On the shaft 8 at each pull of the series is fixed a toothed wheel or pinion 10, each of which is adapted to gear under certain conditions with a curved swinging toothed sector or rack 11, and each of these racks is pivotally attached at its lower end to a swinging arm 12, which latteris pivoted at its rear end to the frame at to. As the pulls are; provided with like mechanisms I will describe minutely but one of the latter. At its free end the arm 12 has an upturned branch 12,.

which bears a laterally-projecting stud or roller12, and when the pull is pushed in or' home, as represented in Fig. 1, this stud,-

rests on the lower portion of a cam flange or way 13 on the lower side of the pull 1,

and the rack 11 is permitted to drop down and out of gear with the pinion 10; but; when the pull is drawn out an inclined face or step 13 (see Fig. 1) on the cam-flange 13} takes under said stud 12" and lifts it, to-; gether with the rack and arm, until the teeth of the rack engage those of the pinion. This engagement is effected near the beginning ofcommunicated to the adding mechanism be fore described, and as each pull has a uni form and limited movement,and each acts to move its rack to an extent corresponding to. the denomination of the pull, the addingi mechanism will be moved to the proper extent by eachpull.

When the pull 1 is pushed in again, the rack does not rotate the shaft 8 backward, as back rotation of this shaft is; prevented by means of a ratchet-wheel let thereon and a spring-pawl 15, pivoted to the.

frame of the register.

As the pull moves:

back the rack remains in gear with the pin-i ion until the stud 12" passes down the incline, on the cam-flange 13, when the weight of the parts causes the rack to drop out of gear with.

the inion and a s rin 15, attached at one D 1 p s end to the rack and at its other end to the: arm 12, draws the rack back to its first position, where it rests against a stop. I prefer to make this back stop adjustable, for rea-,

sons that will be hereinafter explained. As

here represented it consists of a screw 16, which screws through a fixed bar 17, extend ing transversely across the frame over the pulls, and is provided with a lock-nut 16'. When the rack is rocked or pushed forward by the pull to the full extent, it strikes or is arrested by a front stop, consisting of a screw 18, which screws through a bar 19 on the frame and is furnished, also, with a lock-nut.

It is essential to the proper operation of the adding mechanism of the register that the several racks 11 shall play accurately between limiting-stops and that each rack shall be swung or moved forward a distance proportioned to its denomination. For example, if we assume that each tooth of the rack corresponds to 5, then for 15 the rack will have a movement equal to three teeth, for 2O it will have a movement equal to four teeth, for 35 it will have a movement equal to seven teeth, and so on for all denominations. This difierenee in the movements of the several racks may be attained in several ways. As here shown, I attain the end by means of the adjustable-screw back stops 16, which are so set as to limit the extent of backward movement of the rack and stop them. at various points, as clearly seen in Figs. 1 and 1.

I have, as before stated, shown only enough of the register to illustrate the operation of my present invention. The portions not shown may be constructed like those illustrated in my former patent, to which I have referred. If the pulls are arranged in tiers, as in my said patent, it will only be necessary to gear the shaft 8 of any tier to the stud-wheel 7 by the ordinary gearing mechanism, with which all workmen are familiar.

The projecting part 14 may as Well be a simple stud and the stud 11 on the rack 11 may as well be any part of the rack arranged to project into the path of the stud 14 on the pull. So, also, the stud 12 on the branch of the arm 12 may be simply a part of said branch or of the arm arranged to engage the cam-flange 13.

Having thus described my invention, I claim 1. In a registering apparatus, the combination, with a sliding pull and an adding-wheel to be rotated by the operation of said pull, of a shaft arranged transversely over the pull and geared to the adding-wheel, a pinion on said shaft, a swinging rack adapted to gear with said pinion and to be actuated by the pull, and means,substantially as described, for putting said rack into gear with said pinion when the pull is drawn out, substantially as set forth.

2. In a registering apparatus, the combination, with a sliding pull provided with a cam 13 and stud let and an adding-wheel to be rotated by the drawing out of the pull, of the shaft 8, arranged over the pull, mechanism which gears said shaft with the adding-wheel, a pinion 10 on said shaft adjacent to the pull, a swinging arm 12, provided with a stud which engages the cam on the pull, whereby the arm is raised when the pull is drawn out, a rack or sector 11, pivotedly attached to said arm and adapted to be put into gear with the pinion 10 by the raising of the arm, said rack having a stud arranged in the path of the stud 14 on the pull, a spring which retracts the rack, and a back stop for said rack.

S. In a registering apparatus, the combination, with two or more sliding pulls arranged abreast and an adding-wheel to be actuated by the drawing out of either of said pulls, of a shaft arranged transversely over said pulls and geared to the adding-wheel, a series of IIO pinions on said shaft, one at each pull, a series of vibrating racks 11, one for each pull,

In witness whereof I have hereunto signed my name in the presence of two subscribing 10 means carried by the pulls for lifting their Witnesses.

respective racks into gear with their respective pinions when the pulls are drawn out, back stops for the respective racks, and retracting-springs for the same, substantially as set forth.
