BLAST-GAS BURNER.

Specification of Letters Patent.

Patented Oct. 29, 1907.

Application filed December 2'7, 1906. Serial No. 349,596.

To all whom it may concern:

Be it known that l, Josnrn SIMMENDINGER, a citizen ol the German Empire; and a resident of Wenigenjena, Germany, have invented certain new and useful Improvements in Blast-Gas Burners, of which the following is a specification.

This invention relates to blast-gas burners and more particularly to a device for cutting-off the gas supply at the same time when the supply of air under pressure is cut (Err. The device is self-acting, and when in operation it allows only such quantity of gas to pass to the burner as is required for the byliame. The cutoff valve is automatically opened by the blast of air under pressure.

In' the accompanying drawings the device is shown by way of example.

Figure 1 is a vertical section through a blast-gas burner furnished with the cut-oft device, which is represented in the position where the full quantity of gas is supplied to the burner, while Fig. 2 shows the cut-off device in the cutting-off position. Figs. 3 and 4 are vertical and horizontal planes at right'angles to the plane of Fig. 1.

In a chamber of the conduit (1 for the compressed air, an axle g is revolubly mounted which projects through the partition which separates the said chamber from the gas-supply pipe f. The axle g is gas-tightly packed in said partition. A wind-wing d is fixed on axle g in the air-chamber and a spring 1' is provided for keeping the axle in such a position that the wind-wing (1 lies horizontally over the orifice of the blast-pipe a. 011 the end of axle g which is situated in the widening of the gas supply-pipe f an' eccentric plate h is fixed in such a manner that when the wind-wing d is in normal, horizontal position, the eccentric-plate h shuts off the orifice of the gas-supply pipe leaving just enough room that the small quantity of gas can pass, which is required to keep the byflame alive. When the blast is turned on the wind-wing d is blown into vertical position against the action of spring 'i and the eccentric plate h is brought into the position shown in Fig. 2, in which the orifice of gas supply pipe f is open, so that the full quantity of gas is supplied to the burner.

What I claim as my invention and desire to secure by Letters Patent, is:'

A self-acting cut-off device for the gas-supply in blast gas burners comprising in combination an axle revolubly mounted in a widening of the air-supply pipe and pro longed through a widening of the gassupply pipe, a spring for securing the axle in its position, a wind-wing fixed upon the axle in the widening of the air-supply pipe in horizontal position and an eccentric plate fixed upon the axle in the widening of the gas-supply pipe in vertical position for cutting-off the supply of gas to the burner, substantially as described and shown and for the purpose set forth:

In witness whereof I have hereunto set my hand in presence of two witnesses.
