Self-collecting gas seller with measuring drum escapement.

Patented in the German Empire on April 26, 1906 .

The invention relates to a self-collecting gas seller with a spring drive standing coin mechanism and with measuring drum escapement, in which a control shaft moving the gas shut-off organ, after coin insertion screwed into the open position, held in the open position for a certain time according to the number of coins introduced and through the gas meter again in

ίο Final position is screwed.

The invention consists in the construction of the details.

The subject of the invention is shown in the drawing, for example.

Fig. Ι shows the gas self-seller in front view, Fig. 2 in side view and partial section, Fig. 3 in plan view.

A disk 1 is assumed as the shut-off device, which closes the gas supply pipe 2 when it is moved; Of course, another shut-off device can also be selected in its place. The disk 1 is displaced by a lever system \, x, y, w. The lever w is connected to this shaft by means of a claw-like fastening which engages in a groove ν (Fig. 3) of an attachment seated on a shaft r . A pin t is embedded in the shaft r and is guided in a helical groove in the hollow hub b of a gear wheel q . With the shaft r a lever arm s (Fig. 2 and 3) is also firmly connected at right angles, which is movable in a section of the hub b of the wheel q and is pulled by a spring 3 in one direction. This arm 5 rests against the pin k of a crank i, which in turn is moved by a worm gear g, which is released for rotation through a certain angle by inserting coins. The gear m, n, 0, p, q is driven by the measuring mechanism of the gas meter.

The device works as follows:

After the coin has passed the Eimvurfskanal d, it dissolves by virtue of its gravity, the blocking of a spring engine from α, the latter a worm shaft g in a known offset therefore not shown in greater detail in turn. Instead of being driven automatically, the worm shaft g can also be driven in a known manner by turning a crank or the like by hand. As a result, a worm wheel h (Fig. 2) is driven by one tooth and the crank i attached to the worm wheel shaft, which with its. Pin k engages in a groove of the gear q , rotated by a certain angle, the lever arm s pressed against the pin k by the action of the spring 3 follows this movement as far as the cutout in the hub b of the wheel q allows. As a result of this movement of the arm s , the shaft r connected to it is also rotated by the same angle, the pin t embedded in it causing a longitudinal displacement of the shaft r by placing it on the helical groove of the hollow hub b . During this longitudinal displacement of the shaft r , on the one hand the lever system w, x, y, \ is pivoted and the shut-off device 1 is opened, on the other hand the end of the shaft r is removed from the drum track u (FIG. 2).

Claims (3)

removed and released the drum. When the gas is now withdrawn, the gear q is moved forward by means of the transmission η, ο, ρ by rotating a screw m (Fig. I) attached to a stationary shaft / screw that is connected to the measuring drum of the gas meter Arm s is kept constantly in the same position as the wheel q by the action of the spring 3. The wall on the other side of the screw groove of the hollow hub b comes into contact with the pin if and thus tries to take the shaft r with it. But this can be ¹ S, because its arm s rests on the crank pin k , and is consequently screwed back into its final position through the screw groove of the hub b of the further rotating wheel q. Here, on the one hand, the rod w, x, y, \ is turned back and the shut-off device is closed, and on the other hand, the measuring drum is inhibited by the shaft r now reaching into its path. By inserting a second coin, the crank i is turned forward again by a part, this releases the lever arm s , the shaft r and the levers W ₁ /, \ are brought into the open position and thus the measuring drum and the gas supply line are released again. When inserting several coins one after the other, the crank i rotates forward by the same number of partial amounts and the pin t now slides along the same number of partial amounts in the screw groove of the hub b. Godfather ν τ claims: i. Self-collecting gas vendor with ■ measuring drum inhibition, in which a control shaft moving the gas shut-off device is brought into the open position after coins have been inserted, held in the open position for a certain time according to the number of coins inserted and brought back into the final position by the gas meter, characterized in that the control shaft (r ) with a pin ft) engages in a helical groove in the hollow hub (b) of a gear (q) that is loosely seated on the control shaft (r) and is usually blocked by the gas meter , and with an arm ( 3) under the action of a spring (3) s) lies against a pin (k) in such a way that when the pin (k) retreats, the arm (s) follows and the control shaft (r) rotates, which now moves in the helical groove of the hollow hub (b) for so long , until arm (s) hits the pin (k) again during the forward rotation of the gearwheel (q) , after which the now fixed control is activated by the gas meter rwelle (r) is shifted into the final position. 2. Self-collecting gas seller according to claim 1, characterized in that the pin (k) sits on a crank (i) which is rotated by the coin mechanism (a) in a manner known per se by an angle corresponding to the respective amount introduced. 3. Self-collecting gas seller according to claim 1 and 2, characterized in that the measuring drum is inhibited by the control shaft (r) engaging in its final position in the drum track (u) .
