ALFRED E. DETIVILER, OF CHICAGO, ILLINOIS, ASSIGNORTO THE MILWVAUKEE GAS STOVE COMPANY, OF MILIVAUKEE, IVISCONSIN.

GAS-STOVE BURNER.

SPECIFICATION forming part of Letters Patent No. 575,052, dated January 12, 1897.

Application filed May 22, 1896. Serial No. 592,525. (No model.) I

lb all whom it may concern:

Be it known that I, ALFRED E. DETVVILER, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gas-Stove Burners; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The main object of my invention is to facilitate the lighting and regulation of burners which are inclosed or not exposed to view or are not easily accessible.

It consists, essentially, of a burner having one or more gas-discharge apertures, or series of apertures, extending from the inside to the outside of the stove, that portion of the apertures outside serving to light the burner, a gas and air supply connection tapping the burner at a point removed from its lighting extension, and a cut-off controlling the supply of gas to said extension.

In the accompanying drawings like letters designate the same parts in both figures.

Figure lis a plan view of a burner to which my improvement is applied; and Fig. 2 is a perspective view of another form of burner, showing a modification of my improved lighting and regulating device.

Referring to Fig. 1, illustrating a form of burner now in common use, consisting of a shallow-chambered casting A with gas-discharge apertures in the upper or under side, B designates a lighting and regulating extension formed with or applied thereto and projecting through the wall 0 of the stove-casing. It is formed with an aperture, or series of apertures, extending from the outside to the inside of the casing in communication with or in proximity to the apertures in the body of the burner, so that when the gas issuing from the apertures in the extension is lighted it will communicate its flame through an opening inthe casing, as shown in Fig. 2, to the gas issuing from the apertures inside, and thus light the concealed part of the burner within the stove. D designates a plug loosely fitted inside of the extension 13 and adapted, when thrust into the same, to close the aperture or apertures therein outside of the casing.

Referring to Fig. 2, the lighting extension B of the burner outside of the casing O is provided with a rotary tubular plug or valve D, which has a longitudinal slot cl in one side, which may be turned into and out of range with the gas-discharge aperture or apertures in said extension, so as to control the supply of gas thereto without affecting the supply to the apertures of the burner inside the casing.

The apertures in the lighting extension of both forms of the burner corresponding in size or area with those inside, the size, condition, or quality of the flame within the stove may be determined from that outside of the casing, so that said extension not only affords means for lighting the concealed and inaccessible portion of the burner, but also for determining the condition of the flame for the purpose of regulation, which is accomplished in the usual way by a cook or valve 6 in the gas-supply pipe of the stove.

E designates the gas and air supply connection and mixing-chamber of the burner, which taps the same at a point removed from its lighting extension, so that the position of the valve or cut-off in the lighting extension will not affect the supply of gas to the body or main portion of the burner Within the easmg.

I do not wish to be understood as limiting myself to the exact details herein shown and described, as they may be variously modified within the spirit and intended scope of my invention; as, for instance, the form of the burner and the construction and arrangement lating connection, as wellas the construction and arrangement of the cut-off controlling the supply of gas to the lighting extension, may be modified in various ways without materially affecting the operation of the device.

I claim-- I 1. The combination with the casing of a stove, of a burner having a gas and air sup ply connection and one or more gas-discharge apertures inside of said casing, and provided with a lighting extension projecting outside of its gas and an supply, mixing and regu of said casing, and having one or more gasdischarge apertures in communication with or proximity to the apertures of the burner inside of the casing which has an opening for the connnunication of flame from the apertures outside to those inside, and a valve or cut-ofi? controlling the supply of gas to said lighting extension, substantially as and for the purposes set forth.

2. The combination With the fire-chamber of a stove, of a burner-pipe located Within the fire-chamber, extending outside the stove, and provided with a series of apertures extending therealong from the inside to the outside of the fire-chamber, said fire-chamberhaving an opening adjacent to the series of apertures and the apertures outside of the firechamber serving as lighting apertures, and devices for supplying and mixing air and gas, tapping the said burner-pipe at a point removed from the lighting apertures, substantially as and for the purposes set forth.

3. In a gas-stove, a burner provided with gas-supplyingand air-mixing devices, and an extension projectiugoutside of the stove, and provided with a series of lighting-apertures, and a valve located in said extension, sub stantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two Witnesses.

ALFRED E. DETWILER.
