Description

Economy clock with drive escapement The invention relates to an economy clock, in which the inserted coin swings out a lever protruding into the coin channel, who releases the drive for a limited time.

The well-known savings clocks of this type are extremely complicated Construction, which can only be assembled by skilled workers as a result. Their consequently quite high price prevents their further spread.

The invention now aims to remedy this and a savings clock of the opening to create mentioned genus, the structure of which is largely simplified, so that the Assembly of the individual parts, which are limited to a minimum, even by less experienced people Manpower can be done. The essence of the invention is seen in the fact that immediately on the one constantly pushed into its stopping position by an auxiliary (spring or the like) Coin lever a drive in certain periods of time in front of a hinged nose influenced, appropriately spring-loaded Einklinkheb.el with an upper and a lower incidence detent is hinged, the latter with associated detent members (Pens or the like) interact when inserting one or two coins. The one on the latch handle The hinged nose can only move to a limited extent on both sides (stop pin or the like) and lies in the area of a cam driven by the drive. The establishment can be used for various large pieces of money and is extraordinary in its structure simple and therefore extremely insensitive. As a result of their few, easy to manufacture and provides individual parts that are easy to assemble even by inexperienced workers the price is very low, which enables it to be widely used.

An exemplary embodiment is shown in the drawing with the omission of the Parts that can be dispensed with for the explanation are shown.

Fig. I is the front view of the switching device at standstill the clock.

Fig. Z shows the device after inserting a coin.

Fig.3 shows the device after inserting a second coin.

The coin falling through the coin channel, not shown, presses provided with the stop spring 3 coin lever i, which is rotatably mounted about the axis a is down. The stop spring 3 gives the unrest q. free and the clock starts running. The downward movement of the coin lever i also goes around the axis 6 on the coin lever rotatably mounted latching lever 5 down and falls under the pressure of the spring 7 with its upper notch 8 'over the pin B. In this position (Fig. Z) the Latching lever 5 and thus also the coin lever i are held, and the work runs.

As the work progresses, the cam 9 (Fig. Z), the with the drive is coupled, clockwise. After a Rotation of the cam q presses the same on the cam articulated on the latching lever5 i o; which is limited in its movement by the pin i i on both sides. As a result, the latching lever 5 is pressed to the right, and the catch 8 'comes off Pin 8 free. Under the course of the spring 12, the coin lever i goes with the latch lever 5 high, the former stopping the unrest 4. by means of the spring 3 and on the stop pin 13 is recorded.

If the restlessness and the course of the work are not to be inhibited, so, before the work comes to a standstill, another coin must be thrown in will. The coin lever i goes down with the latch lever 5 until the latter falls with its lower detent 14 'over the pin 14 (Fig.;). The feathers 7 and 12 then hold the levers i and 5 in this position with pin 1 4..

The cam g now brings about the completion of its rotation by impact on the nose io (Fig. 3) by temporarily swiveling out the latch lever 5 the arrangement back into the position shown in Fig. 2 and then after another 2q. Hours, if not by inserting a coin the running time again. extended becomes, in the position according to Fig. i, whereby the work is stopped.
