Application filed July 11, 1908. $crial No. 325,701,

To all whom "it may concern.

Be it known that 1, WoLnEMAR REINHOLD Hnmrrz, a citizen of the Kingdom oi Saxony, and resident of Chemnitz, Germany, (whose post-oilice addressis Neefestrasse 24,) have invented certain new and useful Irn provemcnts in Cash-Registers, of which the following is a specification.

My invention relates to a cash register having two-part transmissionsegments tor indicating, printing, adding, etc.

For the purpose of insuring a greater degrce of safety, I employ in place of the single latch usually used, a double coupling-latch, the one part of which, by striking obstruc tions introduced into its path, first causes release of the other part, whereupon the two parts of the segment can be uncoupled.

()no form of construction of the invention is illustrated in the accompanying drawing, in which Figures 1 and 2 are two vertical sections through the upper portion of a cash register fitted with the new device, the operative parts being shown in two di'll'erent positions. Figs. 3 and a are enlarged detail views, showing in elevation in two positions, the devices for coupling and. for uncoupling the two parts of the segment. Fig. 5 is a plan of Fig. 4.

in the case 1'oi' the register there islocated the main shait 2, actuated by a crank 2 in wel l-known manner. segments 3 and cams 4. are rigidly secured. Below the shaft 2 there is a second shaft 5, u )on which there are mounted, with capa- On this shaft 2 toothed bility of turning, segments 6 and 7 and dou- I ble-armed levers 8, 9.

The segment 6 has a lug 10, in which a short shaft 10 is mounted, this shaft connecting the lug with the longer lever-arm 8. The other lever-arm 9 is toothed. Thesegrncnt 3, mounted on the shaft 2, on rotation comes into engagement with the teeth of the lever-arm 9. presents a hook 11, below which there is a slot 12.

The top edge of the segment 7 with ratchet teeth, with whioha pawl 13 engages and thus arrests the segment. At the end of this segment two latches .14,"-15 are The free end of the segment 6 is furnished provided, eachconsisting of a peculii'n'ly'v shaped member turning on a common pin 16. In front ofthese two latches is a pin 17, to which is secured a satcty hlock 17, held in position by a spring 17*. The latch 14 has 23, which his the slot a finger 18, which rests on the block 1.? and is rounded below, so that'on pressure being applied to the latch, the part 1? can he pressed back. the segment 7 and at 19 is roundcdoii" toward both sides. "the second latch-15 has a finger The latch 14- projects above 20, which. likewise on the block 17 but is not rounded bciow, so that pressure on the latch 15 will not eaus the block 17 to'retreat. The finger 20 is hook d on. the upper edge at 21, so th it may with the hoot: 11 oi the segment 6. The portionof the latchlo which projects above the segment '7 somewhat smaller than the corresponding portion of the latch. 1a, and is provided with a shoulder 22, which protrudes shove the other latch 15. Projcctii'ig from the segment 7 is a pin 32 at the end of the other segment 6. The extent of motion of the two segment-parts h, 7 is limited hythe two stops at, Between the shafts 2 and 5 there is mounted a lever 26, whose end rests on the segment 6.

The method of operation oi? the apparatus is as follows:1l.iet itbe assumed that a registration has been el'l'.. ;ted by means of the shown in Fig. 1) and toe fifth eighth key (as key is now depressed (l1 2). [is Fig. 1 shows, on commencement of rotation of the crank the two toothed segments 3 and 9 will 'mesh with each other, whereby the lever 8, and thus the segment 6,

will be actuated. When the end of the segment 6 strikes the in 23, the segment 7 will be actuated also, icing turned as far as the stop permits. This position of the parts is shown in 1:

It is obvious from this figure that this moment the two segments 3, 9 leave each other, while at the same time the cam 4 descends upon the intermediate lever Furthermore the hooked end 11 of the segn'lent s will snap into the hook-21 of the latch 15. This coupling of the parts is ellected by the iuclinedouter edge of the hool -11 first pressing against the finger 18 0f the latch 1-5 which yields and thus presses back the block 17, so that the hook 21 of the finger 20 is now also able to yield. hen the two hooks 11 and 21 have engaged, the latehesla and 15, to gether with the block 17, will return to their initial position. The hloclcl? then lies be low the finger 20, whereby unintentional uncoupling of the two segments rendered impossible (Fig. 3).
