Die vorliegende Erfindung betrifft Kontrollkassen, bei welchen der Ablauf der Anzeigetrommeln gegen die Tasten durch Federoder Gewichtskraft (wie z. B. bei der durch die schweizer. Patentschrift 15158 bekannt gewordenen Kontrollkasse) erfolgt, und besteht im besonderen in der Anordnung eines Sperrwerkes, durch welches der durch die Federn bezw. das. Gewicht bewirkte Rückschlag des Übertragungsmechanismus beim Aufschlagen auf die Tasten unschädlich gemacht wird. The present invention relates to checkout registers in which the display drums flow against the keys by spring force or weight (as known, for example, from the Swiss patent specification 15158 which has become control cash desk), and consists in particular in the arrangement of a Barrage, through which the BEZW by the springs. the weight caused kickback the transmission mechanism is rendered harmless when the keys are hit.

Auf der Anzeigewelle 1 sitzen fest auf einer Hülse die Anzeigetrommeln 2 und daneben lose drehbar je ein Federhaus 3, dessen äußerer Umfang als Sperrad ausgebildet ist. In diesen Federhäusern liegen Federn 4, deren äußere Enden mittels Federhaken 5 an den Federhäusern 3 und deren innere Enden durch Federhaken 6 an den Naben von Zahnkolben 7 befestigt sind, welche lose auf der Welle 1 sitzen und an denen die Trommeln 2 befestigt sind, während sich die Federgehäuse lose auf den Naben drehen. In die Sperräder 3 greifen Sperrklinken 8, welche lose drehbar in den Lagern 9 hängen. In die Zahnkolben 7 greifen Sektoren 10, durch welche unter Vermittlung- von Bolzen 11, Hubkulisse 12, Kurbel 13, Zahnkolben 14, Sektorhebel 15, Exzenter 16, Zahnstange 17 und Schublade 18 beim Öffnen der Schublade die Federn 4 gespannt werden. Die Sperrklinken 8 verhindern ein Ablaufen der Federhäuser 3 und Anzeigetrommeln 2 links herum (Fig. 1 und 2). Die Spannung der Federn 4 pflanzt sich durch die Kolben 7, Sektorräder 10, Kolben 19, Räder 20 auf Zahnstangen 21 fort, welche in der Nullstellung an den Nulltasten 22 anliegen. Wird nun zum Zwecke des Anzeigens eine Betragtaste 23 niedergedrückt, so hebt sich die Nulltaste 22 der betreffenden Tastenreihe in die Höhe, worauf die Zahnstange 21 durch die Feder 4 gegen die Betragtaste 23 gestoßen wird.Fig. 4 is a plan view of the lock spring.
On the display shaft 1, the display drums 2 sit firmly on a sleeve and next to them, loosely rotatable, a barrel 3 each, the outer circumference of which is designed as a ratchet wheel. In these barrels there are springs 4, the outer ends of which are fastened by means of spring hooks 5 to the barrels 3 and the inner ends of which are fastened by spring hooks 6 to the hubs of toothed pistons 7, which sit loosely on the shaft 1 and to which the drums 2 are fastened, while the spring housings rotate loosely on the hubs. Ratchet pawls 8, which hang loosely rotatably in bearings 9, engage in ratchet wheels 3. Sectors 10 engage in toothed piston 7, through which springs 4 are tensioned when the drawer is opened, with the aid of bolts 11, lifting link 12, crank 13, toothed piston 14, sector lever 15, eccentric 16, rack 17 and drawer 18. The pawls 8 prevent the barrels 3 and display drums 2 from running off to the left (FIGS. 1 and 2). The tension of the springs 4 is propagated through the pistons 7, sector wheels 10, pistons 19, and wheels 20 on toothed racks 21 which, in the zero position, rest against the zero keys 22. If an amount key 23 is now depressed for the purpose of displaying, the zero key 22 of the relevant row of keys rises up, whereupon the toothed rack 21 is pushed against the amount key 23 by the spring 4.

Die bisher beschriebenen Mechanismen gelten als bekannt.The mechanisms described so far are considered to be known.

Durch das Aufstoßen der Zahnstange 21 auf die Tasten 23 entsteht ein Rückschlag, der auf die Anzeigetrommeln, Additionsräder und Typenwellen von schädlichem Einfluß sein kann, indem diese Mechanismen unter Umständen eine Einheit überspringen könnten.Pushing the rack 21 on the buttons 23 causes a kickback, the can have a detrimental influence on the indicator drums, addition wheels and type shafts can, in that these mechanisms could skip a unit under certain circumstances.

Um diesen Rückschlag unschädlich zu machen, sind neben den Anzeigetrommeln 2 und den Federhäusern 3 Sperräder 24 mit den Kolben 7 fest verbunden. Auf besonderer Welle 25 sitzen lose Sperrklinken 26, welche in die Sperräder 24 eingreifen, wogegen auf der Welle 25 Mitnehmer 27 festsitzen. Auf diesen sitzen Federn 28, die gegen die Sperrklinken 20 drücken und dieselben entweder gegen die Sperräder 24 (Fig. 2) oder gegenTo make this kickback harmless, next to the display drums 2 and the barrels 3 locking wheels 24 firmly connected to the pistons 7. On special Shaft 25 sit loose pawls 26, which engage in the ratchet wheels 24, on the other hand the shaft 25 driver 27 sit tight. On these springs 28 sit, which against the pawls Press 20 and the same either against the ratchet wheels 24 (Fig. 2) or against

Claims

press the driver pins 29 (Fig. 1). Small levers 30, which are connected to a control rod 32 by joints 31, are firmly seated on the shaft 25. The lower end of the control rod 32 is connected to an angle lever 33 which is rotatably mounted at point 34 on the base plate 35. The other end 33 ** of the lever 33 engages in a slide 36 which has two lugs 36 ^ and 36 *. This slide is arranged displaceably on the base plate 35 and its lugs 36 ″ and 36 * are in the same plane with the release lug 37 of the drawer 18. A second stop lug 38 is located at the end of the rack 17 attached to the drawer (FIG. 1 ) which impinges * when pulling out the drawer to the stop lug 36. Laterally of the slide 36 is. _f and on the base plate 35, a lock or incidence spring 39 (Figure 3 secured 4) which, depending on the position of the slide 36 in the incision incident from the slide. the displacement of the slider 36, the control rod 32 upward (Fig. 2) or pushed downward (Fig. 1) and thereby inserted the locking pawl 26 into the ratchet wheel 24, or lifted off from the same.

The process when using the cash register is now as follows:

If the racks 21 are in their zero position when the drawer is opened, so the springs 4 are tensioned and press the racks against the zero keys 22. The stop 38 then strikes the stop lug 36 ^, the lever arm 33 is pivoted to the left and the control rod 32 has raised, so that the pawl 26 rests loosely in the ratchet teeth of the ratchet wheel 24 (Fig. 2).

If one of the keys 23 is now depressed for the purpose of displaying an amount, so that the zero key 22 is raised, the rack 21 runs against the depressed key; with it rotates wheel 20, piston 19, sector 10 and piston 7 with the firmly connected Ratchet wheel 24. Ratchet wheel 24 runs around to the right under the loosely resting pawl 26, which is in the outgoing Teeth collapse. Will now by hitting the racks 21 on the Buttons 23 of the mechanism 21, 20, 19, 10, 7 and ratchet 24 spring back, this is due to the pawl 26 and the teeth of the Ratchet wheel 24 prevented. ■

When the drawer is closed, the slide 36 is ^{pushed back by the stop lug 36 s} by means of the stop 37, the angle lever 33 pivots from left to right, the control rod 32 is pulled down and the pawl 26 is pulled out through the joint 31, the driver 27 and the driver pin 29 the ratchet wheel 24 lifted out (Fig. 1), so that when the drawer is reopened, the springs 4 by means of the members 17, 16, 15, 14, 13, 12, 11, 10, 7 can be tensioned again or. the ratchet 24 can rotate counterclockwise against the ratchet teeth.
