This invention relates to gas burners and has for itsV object the production of a simple and efficient gasburner which is provided with a plurality of substantially sages extending throug being" provided with l,gas outletsv communicating with thediamond-shaped openings for the pur-= 1 designates the pose of mixing the diamond-shaped air pash the entire body, the body gas with air and facilitating the heating of the burner.

of the burner showing the the expansion plug therein; and

taken on line '7-7 rof Fig- By referring to the drawing, it will be seen that iron or other larged centrally located body which may be formed of cast suitable material having an encollar formed thereon, and

indicated by the numeral 2, from which projects a nipple 3, the nipple V4, for the The body being internally threaded as at purpose of receiving a gas supply pipe. 1 has one side or end wall formed with a transversely extending channel 5 which communicates with a pilot light pipe 6 for supplying gas to the channel 5, this channel 5 communicatiing with the outer face 7 of the burner as shown at 7 in Figure 5, and constituting a pilot light therefor.

The body 1 is provided with a plurality ofclosely arranged substantially diamond-shaped openings 8 which extendv transversely through the body 60 andere surrounded by walls 9 extending from the rear wall 10 to the front wall l1 of the body 1, as shown clearly in Figure 4. These walls Q will.v permit the'gas to freely pass aroundthrough the channels 12 formed inthe body between the vari- 55 ous substantially diamond-shaped openings or air passages 8 and freely circulate through the body, the channels l2 communicating with the nipple 3 and supply pipe which is adapted to be threaded into the internally threaded nipple 3 shown in 70 Figure 2. The gas passes into the hollow body as shown by the arrows in Figure 2, and will then be free to circulate between the various diamondshaped openings 8, or the walls 9 thereof, and be y evenly distributed over the entire body. The walls 9 of the openings 8 are each provided with gas discharge openings or oriiices 13 which preferably extend at an angle of approximately 45 degrees to the longitudinal axis of the openings 8, as shown in Figure 7. A dent 14 is formed in each wall 9 80 directly in advance of the discharge end of the gas opening or passage-way 13, as shown in Fgure 7, for the purpose of causing the stream of gas passing through the passage-way 13 to be broken up in a spray so as to be caught by the 'V` air passing through the openings 8 in the direction as shown by the arrows in Figure 7, and carried to the outer face of the carborundum plate 15.

As shown in Figure 4, the body l is provided with a forwardly extending outer iange 16 which 90 carries an inner asbestos lining 17, and a flat carborundum plate 15, previously mentioned, is seated upon the front wall 11 of the body l and vabuts against the asbestos lining 17, this asbestoslining 17 constituting an expansion joint to 95 take up the expansion and contraction of the respective materials from which the body 1 and the plate 15 are made. The carborundum plate 15 is provided with registering substantially diamond-shaped openings 18 extending trans- 100 versely thereof which diamond-shaped openings 18 are adapted to register with and form a continuation of the openings 8 formed in the body 1.

The body is formed of cast iron and in each of its marginal walls 19 there is provided a 105t threaded opening 20 within which a threaded plug 21 is positioned, the threaded plug 21 being provided with a squared or other socket 22 to facilitate the threading of the plug into position. The plugs are made of steel or any suitable man' terial which will permit expansion and contraction of the walls under the action of heat and cold without cracking the cast iron from which the frame is made.

From the foregoing description, it will be seen that a very simple and efficient as well as cheap burner construction has been provided which will constitute an efficient heating means, and it should be understood that the burner may be supported in any suitable or desired manner.

By positioning the substantially diamondshaped openings within the body of the burner in staggered relation to each other .around the supply nipple 3, the front wall will have an unbroken intermediate portion in front of the nipple which will be struck by the gas entering the body and cause the gas to spread and be distributed throughout the interior of the body. It should be understood that the pilot light 7 may be located in any suitable or desired position upon the face of the burner without departing from the spirit of the invention and certain other detail changes in the mechanical construction may be employed also.

In carrying out this invention, it should be understood that the gas will pass in and through the body in the direction as indicated by the arrows in Figure 2, and upon striking the unbroken central portion of the front wall in front of the inlet be circulated around and between the various openings 8 and then discharged out through the gas discharge passageways or openings 13 into the passages 8 where it will be thoroughly mixed with air passing through the registering passages or

openings

8 and 18 and carried toward the front of the carborundum plate l5 Where the gas will be ignited and burn in the usual way.

Having described the invention, what is claimed as new is:

A gas burner comprising a hollow body of cast iron constituting a gas reservoir and having front and rear walls and marginal walls, a plurality of conduits extending through said body and opening through the rear wall and front Wall thereof, said conduits having opposed side walls integrally united to the front and rear walls of the body, the walls of said conduits being each formed adjacent its front end with a gas discharge opening extending forwardly at an incline into the conduit and terminating in spaced relation to the front end of the conduit, the walls of said conduits being each also formed with an indentation located in front of and spaced forwardly from a discharge opening for breaking up streams of gas into a spray when discharged into the Conduit, steel plugs screwed into threaded openings formed through marginal walls of said body, and a pilot burner associated with said body.
