PATENT LETTERING

CLASS 26: Gas preparation and lighting.

with electric gas remote control.

Patented in the German Empire on November 28, 1897.

The present invention relates to a remote ignition device for gas burners in which the gas shut-off device is actuated by air pressure, while the ignition is actuated by the electric current is effected.

Remote ignition devices operated by air pressure are already known per se, e.g. B. by English Patent No. 86 12/1896. Likewise, by patent specification No. 2405 1, remote ignition devices are actuated by air pressure known, in which the ignition is effected by the electric current.

According to the present invention, the actuation of the one that shuts off the gas line takes place Piston by the displacement of a piston that can be displaced in an air pressure cylinder the piston rod of which a contact pin is attached, which during the displacement of the Piston makes the Contact.

Such a device is illustrated on the accompanying drawing, in which Fig. Ι the displacement of the at the actuation point attached .Kolbens and to establish the electrical connection during this Displacement serving device shows in section. Fig. 2 shows a spread out in a plane Part of this device, while Fig. 3 shows the burner together with the second piston and the ignition device likewise in section and FIG. 4 the burner piston itself in view represents.

As can be seen from FIGS. 1 and 3, the apparatus A or A, which is set up at a point remote from the burners and which can be operated by hand, is shown. the housing α α ^{1 of the} same, in which the displaceable piston b is inserted, is connected by a pipe a ¹ to a housing d connected between the gas line and the burner tube g , in which the second piston d ^l is located.

Accordingly, a certain volume of air is enclosed between the two pistons, which when the piston b is pressed down transfers the pressure generated thereby to the piston d ^l and causes a corresponding displacement of the same, but when the piston b is lifted it is sucked in and thereby the piston d ^l into its Returns initial position. The latter piston is plungerartig designed and crossing on opposite sides of its wall with it slots rf ² rf ⁵ .versehen, of which the former in each position of the piston d ^v the compound of the burner g with the Kolbenhöhlung prepared and according to the same time of the guide of the fixed approach rf ⁴ , the plug d ³ in this slot prevents rotation of the piston. ' The second slot rf ⁵ is made in such a way that, when the piston is in the normal position, the gas inlet opening d ⁶ is blocked by the piston, while when the piston is ^{pushed forward, the slot d 5} passes through the opening d ^% , so that the gas enters the Burner can flow.

The displacement of the piston b is achieved by turning a hand crank or a. Handle c ² caused by the rotated piston rod c, which with a laterally protruding pin c ¹ in a screw thread

shaped slot f ^{1 of} the sleeve-like extension of the housing part a? Leadership has experienced an axial displacement.

The pin c ¹ , which is in constant metallic contact with the slot walls of the housing part a ² over the entire length of this slot, extends with its head through similarly shaped slots of the insulating sleeve a ^s attached to d ¹ and a metal sleeve / sitting on the latter. The slots in the sleeves α ³ and f are, however, widened at both ends at f ² (Fig. 2), so that in the end positions of the crank c ' ² , i.e. at the highest and lowest position of the piston b and therefore when the piston is closed and opened Gas line, the metallic contact between the pin c ¹ and the sleeve f is canceled. Since the latter is now connected by wire h * to one lead ^{wire h 3 of} the ignition device in the burner (Fig. 3), the housing ad ¹ , with which the pin c ^{1 is} in constant contact, through the tube α ¹ and the torch nozzle g is connected to the other lead wire h ' ² , the electrical circuit is established while the crank is turned as soon as the pin comes out of the widened slot end f' ^{2 of} the metal sleeve / into the narrow slot part f ^l and thereby comes into contact with this sleeve . At the end of the movement, the current is interrupted again because the pin c ¹ enters the other widened slot end f ² .

The ignition device, which is activated for a short time in this way, expediently consists of a short platinum wire h, which is connected to the two lead wires embedded in the insulating mass h ¹ and is arranged laterally next to the outflow opening of the burner g- ¹ , together with the one used to protect the insulating mass serving sleeve g ^{2 is} pushed over the ignition device.

The slot d · ⁵ in the piston d ^l can also be arranged in such a way that the opening of the gas inlet opening d ⁶ takes place when the piston b is lifted. The gas pipeline can also be used to return the current, in which case the pipe α ^{λ used} for the supply is isolated from the gas line and the latter is conductively connected ^{to the wire / z 3} and to the sleeve f.

The apparatus may also be several gas burners are used for lighting, is branched in which case either the pipe a ^l for the corresponding number of gas flames in part lines d to the piston housing or the piston housing d, the gas lines from a plurality of branches or upstream of a chandelier and the All burner opened and closed.
