GAS-BURNER.

SPECIFICATION formingpart of Letters Patent No. 732,193, dated June 30, 1903. Application filed February 9, 1903. Serial No. 142,478. (No model.)

To all whom it may concern:

Be it known that I, LEVI F. KNODERER, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvementin Gas-Burners,of which the following is a specification.

This invention relates to gas-burners, and has for its object to provide an improved device of this character which is especially adapted for use in connection with ordinary heating and cook stoves, furnaces, and other gas and oil consuming heaters. It is furthermore designed to have the device complete in itself and to provide the same with means for supporting it within the fire-box without altering or changing the latter in any manner whatsoever.

Another object is to provide for adjustably supporting the device with respect to the grate and also for adjusting the burner propcrly with respect to the air-mixer in order that the entire device may be accommodated to the conditions of each and every individual With these and other objects in view the present invention consistsin the combination and arrangement of parts, as Will be hereinafter more fully described, shown in the accompanying drawings,and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size,and minor-details may be made within the scope of the claims without departing fromthe spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure l is a vertical sectional View of a gas-burner embodying the features of the present invention and applied in operative position with respect to a firebox. Fig. 2 is a cross-sectional view taken on the line 2 2 of Fig. 1, and Fig. 3 is a detail perspective view of the ring for adj ust-ably supporting the device upon the grate.

Like characters of reference designate corresponding parts in each and every figure of the drawings.

As hereinbefore indicated, it is an essential object of this invention to arrange the device for application to a stove, and in order that this application may be clearly understood there has been shown in the accompanying drawings a portion of a fire-box or fire-pot 1 and an ordinary grate 2; but it will of course be understood that the form of these common or ordinary parts may be considerably varied without interfering with the present device.

One embodiment of the present invention, as shown in the drawings, consists of a cylindrical mixer 3, which is open at its top and bottom and is provided at its lower end with crossed bars 4, preferably extending diametrically across the mixer and provided at intermediate points with one or more laterallyenlarged portions having openings therein, which are surrounded by upstanding annular flanges 5. While two such cross-bars are shown, it will of course be understood that one or more than two may be employed. Through each flange 5 extends a set-screw. It is preferable to have each cross-bar provided with terminal ears 7, which are bolted or riveted to the walls of the mixer 3, as best shown in Fig. l.

The seats 5 are designed to receive the burners proper, two of which have been indicated at 8. Each of these burners projects above and below the adjacent cross-bar and is connected to a supply-pipe 9 and is held rigidly in place by the adjacent set-screw 6, and is therefore capable of being adjusted vertically through the seat 5.

At the top of the mixer 3are suitable lugs or projections 10, which rise from the upper edge of the mixer and are designed to support a battle-plate 11, which rests loosel y upon the lugs and is of a greater-diameter than the mixer, soas to project in all directions beyond the external periphery thereof.

Embracing the middle portion of the mixer 3 is a supporting-ring 12, which is formed in duplicate half-sections, the inner marginal edge of each section being provided with an upstanding rim 13, that snugly embraces the mixer. A set-screw l4 pierces the rim and-engages the mixer, so as to connect the 'former to the latter. The abutted ends of theringsections are provided with diametric upstanding flanges 15, as best shown in Fig. 3 of the drawings, and these flanges are pierced by suitable bolts 16, so as to connect the ringsections.

In fitting the present device to a fire-pot,

as shown in Fig. 1 of the drawings, the central grate-bars are removed and a flatmetallic ring or plate 17 is placed upon the remaininggrate-bars and surrounding the opening produced by the removal of the central bars. The ring 12 is supported upon the plate 17, and the mixer 3 is supported within and upon the flange 13 by means of the setscrews 14 and can beadjusted vertically, according to' the conditions of any particular application. The purpose of the plate 17 is to close the openings between the grate-bars and around the mixer in order that all air must pass upwardly through the mixer instead of around the same. When in use, the flames and products of combustion rise into contact with the baffle -plate 11 and then spread radially outward between the upper edge of the mixer and the baflie-plate and into contact with the walls of the fire-box, thereby heating the latter in an effective manner.

From the foregoing description it will be understood that the device of the present invention is complete in itself and may be applied to any ordinary fire-box or fire-pot withoutaltering or changing the same in any manner whatsoever beyond removing such gratebars as may be necessary to accommodate the mixer 3.v

Having thus described the invention, what is claimed, and desired to be secured byLetters Patent, is-

1. A device of the character described,

comprising an open-ended tubular mixer, a burner supported within the mixer, a supporting-flange embracing the mixer, and setscrews carried by the flange and engaging the mixer to adjustably support the latter within the flange.
