GAS BURNER.

Application filed July 14, 1922. Serial No. 574,918.

To all whom it may concern:

Be it known that HERMAN C. DANIELS, a citizen of the United States of America, residing at Huntington, in the county of Cabell and State of lVest Virginia, has invented new and useful Improvements in Gas Burners, of which the following is a specification.

The object of the invention is to provide a gas burner of the Bunsen type suitable and adapted for use in connection with gas stoves wherein provision is made for an e'liicient mixture of the gas and air necessary to support combustion before delivery at the burner orifice or outlet to the end that a uniform flame involving a practically complete combustion of the gas may be attained; and with this object in view the invention consists in a construction and combination of parts or which a preferred embodiment is shown in the accompanying drawings, wherein z- Figure l is a side View, and

Figure 2 is a plan view of a burner en1- bodying the invention and including a pluraliity of units arranged in a body or series.

Figure 8 is an inverted plan view of the same.

Figures 1 and 5 are transverse sectional views thereof respectively on the planes indicated by the lines 4t and 5-5 of Figure 1. Fig. 6 is'an end view of the device.

In the illustrated. embodiment of the invention the burner embodies a plurality of burner units 10 arranged in a battery or longitudinal series connected by upper and lower longitudinal and parallel webs 11 and 12 with the extremities of the latter provided with cross or f-heads 13 for engagement with supporting objects within the stove structure which, however, is not herein illustrated.

Each burner element is provided below the plane of the lower supporting web with a downwardly flared or bell-mouthed inlet 1% into which is projected a jet of gas from a gas supply pipe 15 indicated in dotted lines in Figure 1 and havlng sultable controlling means such as the valve or faucet 16. At its upper end each burner element is provided with a substantially cylindrical nozzle 17 which is terminally closed with the exception of a series of outlets or orifices 18 01 minute area, while between the supporting webs the generally tubular body of the unit which is indicated at 19 is provided with a spherical enlargement forming a globular mixing chamber 20 serving to receive the gas provided by the supply pipe together with air which is suctionally inducted thereinto through the bell-mouth inlet to form a combustible mixture pre liminary to the discharge through the burner orifices. These spherical enlargements are preferably connected in series by the sup plemental bracing webs 21 to produce a rigid structure embodying the several units each of which is provided with its own independent burner orifices of which any desired number from two upward may be employed to suit the purpose for which the burner is designed.

Having described the invention, what is claimed as new and useful is 2- A burner unit comprising an elongated body provided at a point between its ends with a globular enlargement adapted to serve as a mixing and expansion chamber and provided at one end with a cone-shaped air and gas inletsection which is connected with the said chamber by a passageway which is relatively restricted and cylindrical, the body being provided at its opposite end and communicating directly with the said chamber with a cylindrical nozzle having an outlet with the axis of the body, the cylindrical nozzle being of greater diameter than the diameter of the passageway.

In testimony whereof he aflixes his signature,

HERMAN C. DANIELS.
