BURNER.

SPECIFICATION forming part f Letters Patent No. 613,649, dated November 1, 1898. Application filed June 21, 1898. Serial No. 684,065. (No model.)

ToaZZ whom it may concern:

Be it known that we, HARRY M. HAMRIK and WILLIAM S. MILLER, citizens of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Burners, which improvement is fully set forth struction of burner for illuminating purposes;

and the object is to provide a burner of this character wherein the gasolene or other liquid illuminant will be converted into a gas or vapor after having left its source of supply prior to or at about the time of its admission into the burner, means being provided for controlling the supply to said burner and for retaining a large proportion of the heat within the burner in order that a superior gas may be generated therein and a more perfect combustion thereof result.

It also consists of a suitably-supported mantle suspended above and adjacent to the mouth of the burner, whereby the llame as it emanates from the burner and surrounds the mantle will be spread or deflected, so as to increase the illuminating power thereof, and whereby also the heat units which are contained in said mantle may be returned to the burner, and thus intensify the heat thereof to a maximum degree.

It also consists of a burner comprising a shell or tube, a gas-generating chamber lo cated at one end thereof, and a perforated diaphragm located within said tube and intermediate of its ends, means for supplying said gas-generating chamber with gasolene or other liquid illuminant and for controlling the supply thereof to said burner, and means for retaining and intensifying to a maximum degree the heat in said burner when in operation.

It further consists of novel details of conn struction, all as will be hereinafter fully set forth, and particularly pointed out in the claims.

Figure l represents a side elevation of a burner embodying our invention. Fig. 2 represents a longitudinal section of the same,

showing also the preferred arrangement for supplying said burner with the gasolene or other illuminant. Fig. 3 represents an inverted plan view, on an enlarged scale, of a ring to which the mantle is secured and which forms a support therefor. Fig. 4 represents a longitudinal section of the mantle and its adjuncts. Fig. 5 represents a side elevation of the supporting-ring for the mantle in detached position. Fig. 6 represents a longitudinal section of a slightly-modified con struction of our invention. Fig. 7 represents a side elevation of the same, the burner being shown in this instance as provided with an asbestos or other refractory cover.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates the burner, the same consisting of a shell or a tube B, having a series of perforations C near its lower extremity for the admission of air and a series of perforations D near its upper extremity through which a portion of the flame escapes when the burner is in operation.

E designates the threaded neck or extension of a casing F, to which the lower internally-threaded extremity of the shell or tube B is secured, the said casing being provided with a chamber Gr, the latter having a port 'H leading therefrom into the shell or tube B and through which the gas generated within the chamber Gescapes into the burner. The lower end of the casing is provided with a threaded opening adapted to receive the threaded stem K of a needle or similar valve L, which serves to control the supply of gas to the burner, although it is evident that under certain conditions we may dispense with said valve and reduce the size of the port Hin order that a predetermined and continuous supply of illuminant may be introduced to the burner.

M designates a supply-pipe which may lead from any convenient source of supply, (not shown,) and the gasolene or other liquid illuminant may be forced or allowed to pass into the chamber G through said pipe, it being observed that the pipe M in Fig. l leads directly to the chamber G, while in Fig. 2 it is coiled around the burner A before entering said chamber,the latter arrangement being IOO intended to heat the gasolene to a higher degree as it passes through the coil and so facilitate and accelerate the production of the gas.

The interior of the burner A is provided with a perforated or gauze diaphragm P, the same being located slightly below the level of the perforations D, so that as the gases rise within the shell B and commingle with the air drawn in through the perforations C their ascent will be retarded by said diaphragm and a perfect combustion at that point will ensue, the flame being contained'within the said shell or casin g between its upper extremity and the diaphragm will radiate through and heat the burner, and any flame which may pass out through the perforations D will give additional heat to the exterior of the burner, as will be evident.

Q designates a frame, the same consisting of an arm or standard T, having its lower extremity attached to a collar R, the latter being formed with an annular top flange S, adapted to rest upon the upper extremity of the shell or casing B, the lower edge of said collar terminating above the perforations D.

The upper extremity of the arm Q is provided with a laterally-extending support U, which may be arranged in substantial alinelnent with the collar R and upon which pins V of a ring W rest, the latter being secured to and forming part of an inverted conical mantle A', the action of which is similar to that of a VVelsbach mantle.

The ring YV is formed with an annular groove X and an adjacent flange'Y, having radial recesses Z, in which the ends of a plurality of strands of wire are inserted, the same being secured therein by means of a wire B or other suitable fastening, fitting into the groove X and binding the ends of said strands, the lower to the converging ends of wires C, whereby a substantial and effective mantle is secured.

Referring now to Figs. 6 and 7, BX designates a shell or tube similar to that hereinbefore described; but in this construction the lower perforations C are omitted, and in their stead a space OX is left between the lower extremity of the shell or tube and a casing FX for the admission of air into the burner A, to which latter the supply-pipe MX is brazed or otherwise secured. The casin g FX is provided with a port or orifice GX, adapted to receive therein the lower extremity of the supplypipe MX, which latter leads to the gas-generating chamber G, as shown, and in this manner a convenient and substan tial support is provided for the valve-casing, as will be evident.

NXdesignates a cover or casing, which may be composed of asbestos or other refractory material, the same being provided with perforations PX at or near the lower extremity thereof for the admission of air to the burn er, the said cover being designed to inclose the burner in such manner that while serving to extremities thereof being fastened.

retain and intensify the heat therein it will 'in no wise interfere with the free circulation of the air, which may pass up from below the cover and through the perforations PX therein, as described. This cover may be applied to any of the forms of burners herein shown and described and is particularly advantageous in winter time or under conditions where a low temperature prevails.

It will be understood, of course, that the valves for controlling the supply of gasolene or other liquid illuminant to the burner and 'the mantle and other parts or adj uncts specifically described as pertaining to Figs. l to 5, inclusive, and not referred to in connection with Figs. 6 and 7 will be used therewith in substantially the same form.

It has been found in practice that-the best results are obtained by making the ring WV oi' copper, as well as the support U, the standard Q, and the collar R, the mantle A being preferably made of platinum or similar inaterial.
