T0 a/ZZ whom it may concern:

Be it known that I, EMIL OTTo MsoI-IKER, a subject of the German Emperor, residing at Dresden, Germany, have invented certain new and useful Improvements in Cash-Registers, of which the following is a specification.

The present invention has reference to improvements in cash-registers, and relates more especially to that class of registers in which all of the indicator-cylinders weighted at one side are forwardly rotated upon a handle being actuated and rotate back again more or less by reason of the one-sided weight until individually arrested by the key depressed in each particular row of setting-keys.

My invention particularly has for its object to provide means which will retain the indicator-cylinders and accessories in the display position-that is, the position displaying the amount last registered until the neXt amount is about to be registered.

In order to make my invention more readily understood, I will describe it with reference to the accompanying drawings, Figure 1 of which is a side elevation of a cash-register embodying m y new features, partly in section. Fig. 2 is a plan view of four indicator-cylinder systems and adjacent parts, the casing being in section. Fig. 3 is a top plan view of a fragment of one of the bands for and its springpressed stop 11, showing in dotted lines a key, as VIII, and the position assumed by the stop in passing the same and in full lines showing the stop when keyed upon said key.

As shown by way of example, four indicatorcylinder systems are used; but it is obvious that any other number of .them may be employed. These systems comprise each an indicator-cylinder 1, freely rotating on the common axle 2 and having at one side a weight 3. A fieXible band 4 is attached at one end to the cylinder 1 and at the other end to the swinging segment 5, pivoted at 6. Above each band 4 is arranged a row of set-keys I to IX, each one under the influence of a spring 7. (Only two such springs are shown, one eX- tended on key I and one compressed on key VIII.) The lower ends of these keys are beveled and notched and extend through two bars 8 and 9, the latter of which is slidable longitudinally to the bar 8 and infiueneed by the draw spring 10. Upon a key being set-as, for instance, VIII-the slide 9 will first recede and then engage the notch in the key, retaining the latter in its depressed po- Sition. Upon each band 4 there is provided a pivoted spring-pressed stop 11, which upo the band being drawn forwardwthat is, toward segments -slides past the key depressed at the time, but catches behind it when the band travels backward, stopping thereby further rotary movement of the respective indicator-cylinder. For releasing a wrongly-set key there is provided a shifter 12, secured to the slide 9. On both sides of these indicator cylinder systems there is located a Z-shaped lever 13, both secured on the same shaft 20 and connected by crossrods 14 and 15 and a connecting-bar 16. To the shaft 2O is also secured the lower end of the handle 17. Upon the handle being actuated for registering purposes these connected Z-levers 13 rotate downwardly about their pivot, when the connecting-rod 14 engages all of the segments and causes them to rotate accordingly. rIhe bands 4 wind upon the segments, the stops 11 on them passing the depressed keys. Upon the handle now being moved back again the weights on the indicator-cylinders cause the bands 4 and the segments to travel back again until further movement of them is arrested by the stops catching behind the depressed keys in the different rows, when the indicator-cylinders will display the setup amount. Just before the handle 17 attains its final up position the connecting-bar 16 hits against a stop-ledge 18 on the slide 9 and in passing the same causes the slide to recede, freeing thereby the setkeys. In order now to retain the segments in this display position, I provide on the inside of the segments a rack 19 of nine teeth and dispose these teeth in such manner that there is always a gap between them right in front of the connecting-rod 15 whenever one of the segments is arrested by a depressed key. Upon the final back movement of the handle the connecting-rod 15 consequently will enter the gaps in the dierent segmentracks and lock the set indicator-cylinders in the display position until a new forward actuation of the handle frees them again.

By reason of the segments and the Z-levers being eccentrically pivoted they can pass each other upon the forward movement, but will lock, as described, upon the handle passing through its final back movement.

What I claim is- 1. In a cash-register, the combination of a plurality of indicator-cylinder systems, each comprising the indicator-cylinder proper, a Weight at one side thereof, a row of set-keys,

'spring-pressed stop on said band, with a rocking shaft, a handle and rocking levers secured thereon, cross-rods and a cross-bar connecting said rocking levers, and internal racks on said swinging' segments, one of said cross-rods -adapted to engage all of said swinging seg'- ments upon the down movementJ of said handle, the other cross-rod locking with suoli of said segment-racks as are set, upon the said handle iinishing its up movement, and said cross-bar actuating the means for automatically releasing the depressed keys, the parts being constructed, arranged and coperating substantially as and for the purpose set forth.

Q In a cash-register, a plurality of weighted indicator-cylinders, rows of depressible setkeys, means for retaining said keys in their depressed position, segments pivoted beneath said rows of keys, iieXible bands connected at one end to said cylinders and at their opposite ends to said segments, means on said bands to catch and engage said depressed keys when said bands move backwardly and to pass said depressed keys when moved forwardly, and

nmeans for actuating each segment and for releasing said means for retaining said keys in -their depressed position.

3. In a cash-register, a plurality of indicator-cylinders, rows of depressible keys with -means for retaining said keys in their depressed position, segments underlying the rowsof keys, and having a flexible connection With said cylinders, means arranged on said connection whereby the same will engage and loe stopped by said depressed keys when said connection is moving in one direction, and

-vvill pass the same Without stopping said connection when the latter is moving in the opposite direction, and means for actuating said cylinder and in synchronism with said actuating inovement release said means for retaining the keys in their depressed position.

4L. In a cash-register, a plurality of indicator-cylinders, rows of depressible keys, a sliding spring-retracted plate through which said keys project, said plate having a depending projection, pivoted segments, formed on their inner faces with rack-teeth,irregularly-shaped levers having a pair of intermediate connecting-bars for engagement with said rack-teeth, and a connecting-bar at their free ends for engagement with said depending projection of said plate to actuate the same and permit the depressed keys to be released, and means for actuating said segments, connections between said cylinders and segments, and means thereon to engage the depressed keys when moving baekwardly.

5. In a cash-register, a plurality of indicator-cylinders, rows of depressible keys, a sliding plate through which said keys project, means for retracting said plate to retain the keys in depressed position, segments, bands connectingl said cylinders and segments, means on said bands to engage said depressed keys when the bands are moving in one direction and to pass said depressed keys when the bands are moving in the opposite direction, irregularly-formed levers having a pair of connecting-bars intermediate their ends, rack-teeth on the interior of the segments for engagement with said connecting-bars whereby said segments are actuated, a depending projection on said plate, a connecting-bar at the free ends of the segments for engagement with said depending projection to operate the same to release the keys, and means for actuating said segments.

In testimony whereof I ailix my signature in presence of two witnesses.
