Specification of Letters Patent.

GAS-BURNER.

Patented Mar. 16, 11915.

Application filed June 20, 1913. Serial No. 774,791.

burner for natural gas, which shall be highly effective in operation and at the same time simple, compact and convenient in construction, and economical in use. These and other objects of the invention will be in part obvious and in part more fully explained in the following description.

The invention consists in the novel parts,

combinations, improvements and features of construction herein shown and described.

In the accompanying drawings, which are referred to herein and form a part hereof, is illustrated a preferre embodiment of the invention, the same serving in connection with the description herein, to explain the principles of the invention.

Figure 1 is a plan view of a burner for natural gas constructed in accordance with the invention; Fig. 2 is a'diametrical section of the same; and Fig. 3 is a side view thereof.

A burner for natural gas, constructed in accordance with one. feature of the invention, comprises in combination, a pair of concentric gas conduits, each of said conduits having a slit formed in its upper portion, and a supply-pipe communicating to the outer of said conduits.

According to another feature ofthe invention, a plurality of passages communicate between said conduits.

In one embodiment of these features of the invention the slits are formed substantially throughout the entire lengths of the conduits.

According to other features of the invention, each conduit has its lower portion ably and as shown, they are annular in form and are concentrically arranged.

A feature of the invention consists in adapting the concentric rings 5, 6 to burn natural gas from slits and from a common supply-pipe. To this end, therefore, and as shown, a supply-pipe 7 communicates with the outer ring or conduit 5 and preferably flares as it approaches said ring. ()n the opposite or inner side of the ring or conduit 5 a. pipe, 9, which forms a continuation of pipe 7 communicates between said outer ring 5 and the inner ring or conduit 6, said pipe 9, preferably and as shown, tapering from the outer ring 5 to the inner ring 6. It will be noted that by means of the flaring and tapering of the pipes 7 and 9 the gas is inducted into the rings 5 and 6, in a manner calculated to promote a steady supply of gas to both rings without fluctuation or other disturbance. The bottom of each ring 5 and 6 is rounded to facilitate the flow of gas. Preferably and as shown, also, and further to promote this steady supply of gas to both rings, other communications between the rings 5 and 6 are provided, the same consisting in the embodiment herein illustrated of two additional passages 11 and 12, which with the connecting pipe 9 form three passages between said rings 5 and 6 preferably equally spaced apart.

To provide a highly eflicient form of burner slits 13 and 14 are formed in the upper portions of the respective rings 5 and 6, and preferably each slit extends throughout the entire extent of the ring. It will be obvious that with two circumferentially continuous and concentric flames great heat can be obtained and without waste of gas. By rounding each ring at the bottom and tapering it in its upper portion, as shown, the air is induced to approach the place of combustion gradually and without disturbing the flame at the slit.

It will be seen that a burner constructed in accordance with the invention will carry out the objects of the invention while possessing other advantages which will be apparent to those skilled in the art.

In its broader aspects the invention is not limited to the precise construction shown and described or to any particular construction by which the same has been or may be tic practised, as many changes may be made in the details thereof-without departing from the main principles of the inventlon or sacrificing 1ts chief advantages.

I claim:

1. A burner for natural gas, including in combination, a plurality of separate and distinct concentric gas conduits, each of said conduits having a slit formed in its upper portion, and a supply pipe leading to said conduits.

2. A burner for natural gas, including in combination, a plurality of separate and dis tinct concentric gas conduits, each of said conduits having a slit formed in its upperportion and a plurality of communicating passages between said conduits.

3. A burner for natural gas, including in combination, a plurality of separate and disconduits having a slit formed in its upper' portion and extending substantially throughout its entire circumference, a plurality of communicating passages between said conduits, and a supply pipe.

6. A burner for natural gas, including in combination, a plurality of concentric gas conduits, each of said conduits having a slit formed in its upper portion, a supply pipe communicating with and flaring toward the outer conduit, and a supply pipe communicating between said conduits and flaring to a slit formed in its upper ward the outer conduit, saidpipes forming continuations to each other in a radial direction.

, 7. A burner for natural gas, including in combination, a plurality of integral concentric gas conduits, each of said conduits having a rounded bottom, its upper walls converging and a slit formed in its upper portion, and a supply pipe.

8. A burner for natural gas, combination, a plurality of integraLconcentric gas conduits, each of said conduits having a rounded bottom, converging upper walls, and a' slit formed in its upper portions,' a supply pipe communicating with and flaring toward said outer conduit, and a pipe communicating between the conduits and tapering toward the inner conduit, said pipes forming continuations of each other.

9. A burner for natural gasfincluding in combination, a pair of separate and distinct conduits, one surrounding the other, each of said conduits having a slit formed in its upper portion, and a supply pipe.

10. A burner for natural gas, including in combination, a pair of separate and distinct conduits, one surrounding the other, each of said conduits having a slit formed in its upper portion and extending substantially throughout its entire length, a plurality of communicating passages between said conduits, and a supply pipe.

11. A burner for natural gas, combination, a pair of separate and conduits, one surrounding the other, said conduits having a slit formed in its upper portion, and a plurality of communicating passages equally spaced apart between said conduits.

In testimony whereof, I have signed my name to this specification, in the presence ofincluding in distinct two subscribing witnesses.
