JOSEPH HANOK, OF BALTIMORE, MARYLAND.

GASf-BURNER FOR HEATING PURPOSES.

SPECIFICATION forming part of Letters Patent No. 391,606, dated October 23, 1888.

Application lcd March 2, 1888. Serial No. 265,999. (No model.)

T0 all whom it may concern.-

Beit known that I, Josnrn: HANcK, a subject ofthe Emperor of Germany, residing at Baltimore, in the State of Maryland, haveinvented certain new' and useful Improvements in Gas- Burners for Heating Purposes, of which the following is a specification. t

My invention relates to a gas-burner for heating purposes. rIhe device is adapted for heating cooking utensils or anything else to which it is desired to apply heat, and forheating an apartment.

The invention is illustrated in the accompanying drawings, in which- Figure l is a side view of the gas-burner. Fig. 2 is a vertical section of the lower part. Figs. 3 and 4 are top and bottom views, respectively, of the flame-plate. Fig. 5 shows two views of the gas and air spreader plate. Fig. 6 is a view ofone ofthe diaphragms. Figs. 7 and 8 are views of two additional perforated diaphragme.

The gas-burner has a base, a, of any suitable shape. A gas and air receiving chamber, B, is immediately above the base. A mixingchamber, C, is above the receiving-chamber, and is provided on top with a flame-plate, D, and a contracted throat, e, connects the receiving-chamber and mixing-chamber. The said throat e is provided with a packing, c, of plaster-of-paris filled in around the inner tube of said throat to forni a solid foundation between the lower and upper chambers,B C. The base a has an internalvertical pipe, f, provided with a lateral branch air-inlet, f', and an ordinary gas-burner or jet-aperture, g, has position within the said vertical pipe j', whose lower end is closed. Gas is supplied to the jetaperture g by a pipe, g'.

Immediately above the vertical pipe f is a gas and air spreader plate, which consists of a fiat circular flange, h, having perforations h', and a central imperforate downward-pointing cone, t'. The inverted cone z' points down directly over the vertical pipe f. As the gas escapes from the jet-aperture g and ascends the pipe f, air is drawn in at the lateral branch f. Both air and gas are deflected by the point of the spreader-plate and caused to ascend through the perforations h. One or more perforated diaphragme, j, between the spreaderplate and contracted throat c, serve to partly mix the gas and air.

The mixing-chamber C is funnel-shapedthat is, it spreads and widens from the throat e up to the flame-plate D. Vithin the lower part of the chamber C is located a double cone, G', the smaller portion of which fits the upper portion of the contracted throat, so as to direct the gas and air through the opening at the apexes of the double cone centrally into the upper cone-section. To insure the more thorough admixture o f the gas and air, the upper portion of the cone O in the mixingchamber C is provided with perforated diaphragms 7c 7c Za, as many as may be deemed advisable. It will be noticed that the lowerdiaphragms are provided with small diffusedperfoi-ations Z, the object of which is to compel the air and gas in ascending to take zigzag or circuitous paths, so as to insure its uniform admixture. vThe diaphram le is provided with a large central perforation, Z', to direct the mixed gas and air centrally and directly below the dame-plate.

The flame-plate D is provided on its lower surface with division-flanges m, which form passage or spaces n, while the top surface of the plate has gas-holes o from the said passages or spaces. The passages or spaces a on the lower side of the flame-plate are ring-shaped or concentric in the present instance. They may, instead of being separate, be spiral or a continuous winding around. This is immaterial.

The top of the mixing-chamber C has a rimlange, p, and on the inner side thereof an annular seat, Q. The flame-plate D sets down inside of said rini-iiange, and thus it may be removed at any time to afford access to the interior.

The admixed gas and air passing the holes o in the flame-plate D is burned on the upper surface of said plate, and produces a blue flame of great intensity of heat.

The division lianges m give the desired amount of metal to the llame-plate where heat is stored, which heats the gas and augmente the intensity of the heat from the flame. It also causes llame to issue from all the holes alike by producing an equal pressure of gas at all of the holes.

A superheater comprises a cylinder, B, open ICO at the top and bottom and having perforations s in its Walls. This sets upright upon the flameplate D, as shown in Fig. 1. In operation the air may enter the perforations s, and the interior of the cylinder R will be a mass of blue flame. A Vessel or cooking utensil placed above the upper end of the cylinder R will be heated at once. Should the vessel be of sufficient size to entirely close the cylinder R, the said vessel may be supported in any suitable manner a short distance above said cylinder.

By this device a high degree of heat is obtained from the consumption of the minimum amount of gas.

I do not limit my invention to the precise construction shown, as certain of the parts may be altered, changed, or omitted without materially affecting the invention.

Having described my invention, I claim and gesire to secure by Letters Patent of the United tates- A gasburner having in combination a base, a, provided with a Vertical pipe, f, having an air-inlet,f, and a gas-jet, g, a chamber having an inverted cone, e', immediately above the said pipe f, the said chamber terminating at the top with a contracted throat, e, a mixingchamber, C, supported above said throat and provided With diaphragms k k', having small perforations Z, and a diaphragm, k2, having a central opening, Z', and a perforated plate on top of the mixing-chamber, substantially as specified.

In testimony whereof I afiix my signature in the presence of two Witnesses.

JOSEPH HANCK.
