UNITED STATES PATENT OFFICE.

GAS BURNER. I

Application filed June 11, 1925. Serial No. 36,400.

To all whom it may concern:

Be itknown that I, AUoUs'rUs F. THOMP- soN, a citizen of the United States of America, and a resident of Huntington, county of Cabell, and State of West Virginia, have invented certain new and useful Improvements inGas Burners, of which the following is a full and clear specification.

This invention relates to that type of Bun .10 sen gas-burner in which the gas is distributed along a series of burners and injected into each of the burners through a perforation in the pipe, the-burners being, so arranged that the jetof gas dra s in the necessary supply of air,

after set forth.

In the drawing Fig. 1 is a side elevation, partly in sec tion, showing the essential parts of the I W burner;

v Fig. 2 is a plan view thereof, partly broken away;

Fig. 3 is a vertical sectional view. 4 In the drawing annexed, 5 designates the gas-supply pipe provided along its top with a series of perforations 6f spaced to inject a jet of gas into uprighttubes 7 which are, at their upper ends, adapted to be connected to any suitable burner-tips or mixin -chamhers or used as shown, as a multiple unsen burner. s v

The tubes 7 are mounted in a metal bar 8 supported parallel with the supply-tube 5. The support for this tube consists of. a pair of goose-necks 9 formed on the ends of the supporting-bar t5 and provided with holes through which the gas-supply tube 5 passes. Each goose-neck is formed by bending down the end of the supporting-bar and then curving it upwardly, the holes for the gas-pipe as more fully hereinbeing provided in the vertical portions of the goose-neck. This arrangement affords a broad substantial bearing for the gaspipe and also provides a support for a set-screw 1O tapped through the curved part of the goose-neck andhaving its upper end bearing against the gas-pipe, to thus lock the gas-pipe removably in position. .This reinovability of the gas-pipe is desirous because of the need for pipes having varioussized jet-openings 6; this makes the gaspipes interchangeable, enabling me to insert any capacity gas-pipe that may be necessary for the particular burner I am assembling. 7

As is obvious, air is drawn -into each of the burner-tubes 7 by the jet of gas issuing from the gas-pipe, and the gas and air are mixed in the tube and also in the usual mixing-chan ber attached to the upper ends of the tubes. To prevent back-firing, I constrict each tube 7 near its .base by providing an annular head 11 therein. Some or all of these beads may be provided with perforations 12-to drawrnore air into the tubes by the suction created by the upgoing jet, when desired on hertain quality of gas. a

What I claim as new is: A gas-burner of the type herein disclosed embodying a bar supporting a plurality of burner-tubes and having each of its ends bent upon itself to form a U-shaped member, the two legs of each of these members being provided with corresponding holes, a sup ply-pipe extending through said holes, and

set-screws for removably holding the gaspipe in said U-shaped members.

In testimony whereof I hereunto afiir; my signature.

AUGUSTUS FRANKLIN THOMPSON.
