UNITED STATES PATENT OFFICE,

JACOB BARROV, OF VINDFALL, INDIANAI GAS-BURN ER.

SPECIFICATION forming part of Letters Patent No. 468,635, dated February 9, 1892. Application iled August 27, 1891. Serial No. 403.842. (NoA model.)

.To a/Z whom, it may concern,.- Be it known thatI, JACOB BAEEow, acitze of the United States of America, residing at Y reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in natural-gas burners.

The object of the invention is to provide an improved burn er which will effectively consume natural gas without smoking; and it consists of a burner having a body which is made up of refractory material, as fire-clay,

said burner being provided with perforations at its top and sides through which the gas is ejected, the ends of the burner being provided With heads which are connected to each other by a rod, one of said heads being hollow and provided with apertures for injecting and mixing air with the gas on its Way to the burner, as will be hereinafter fully set forth.

In the accompanying drawings, forming part of this specification, Figure l is a longitudinal sectional view of a gas-burner constructed in accordance with my invention. Fig. 2 is avertical sectional viewtaken through the line :n on of Fig. l. Fig. 3 is a longitudinal transverse section. Fig. 4L is aview show ing the application of my invention to aheath ing or cooking stove.

A refers to a casing having, preferably, a rounded top and fiat bottom and which is made up of a single piece of molded material, as fire-clay. The ends of this casing are closed by the heads B and C, which are con nected to each other by a rod or bar D, said heads being provided with flanges, as shown, which abut against the ends of the casing.

The casing has its upper or top wall tapered internally, so that it will be considerably thicker at the end adjacent to the head B than at the end to which the head C is attached, and the upper perforations a o, are of less diameter or size than the perforations a' be neath the same. By providing the tapered walls'and different-sized apertures an equal amount of gas is fed out of each of the apertures and the flame is equalized over the sides and top of the burner. The head C tapers outwardly from the inlet-point adjacent to the point of attachment to the burner, so that the size of the opening therein is larger adjacent/to t-he end of the burner than elsewhere, and this head is provided on each side of the gas-inlet pipe E with openings or apertures ec, and the inner end thereof is provided with an extension with which the rod D engages, so that by screwing the nut on the opposite end of the rod the two heads will be held securely in position. The inlet-pipe E projects slightly beyond the outer ends of the apertures e c, as shown in Fig. 3, and suitable couplings are provided for connecting the inlet-pipe with said head, so that the inlet-pipe can be adjusted with respect to the openings c e to regulate the amount of air which is fed into the burner by the inflow of gas under pressure.

In operation the parts of the device are organized as shown in Fig. l of the drawings, and the end of the gas-inlet pipe is adjusted to suit the conditions of the gas, and when the gas is turned on it iiows through the gasinlet pipe with considerable pressure and draws air with it through the apertures e e. As soon as the gas and air pass into the head C the force of the same commences to diminish and an equal quantity will be distributed to every part of the burner, and the gas hav ing a natural tendency to rise will pass out equally through the larger apertures near the base of the burner and the smaller apertures at thestop.

The rod I), in addition to serving the function of holding the two heads upon the burner, also assists in the distribution of the gas equally throughout the burner, as I have found by experiment that a rod or bar of metal located in such a burner shown acts in a peculiar manner to distribute the gas, and natural gas seems to have an affinity for said rod and will follow the same, soas to assist in assuring equal distribution.

A straight pipe or casing having apertures through which the gases pass for burning is not new; but in practice I have found such ICO construction to be objectionable, as the gas has a tendency to collect and pass out with greater force at the end of the pipe farthest from the point of inlet, and to overcome this objection to a straight pipe I make the inner or hollow portion of the burner of less diameter by having the walls of greater thickness at the end farthest from the head having the injector than the end adjacent thereto.

I am aware that prior to my invention it has been proposed to make a burner of fireclay and provide the same with perforations, andI do not claim such construction, broadly, as my invention; but

What I do claim as new, and desire to secure by Letters Patent, is

l. A burner having a hollow body of ref ractory material and provided with a series of perforations a and a', the diameter of said perforations diminishing from the top to the base thereof, said burner having a tapered inj terior,the largest interior diameter of which tapered in an opposite direction from the interior of the chamber or burner A, and apertures c ein the outer end of said head, and a head B, connected to the head C by a central rod, substantially as shown, and for the purpose set forth.

3. A burner consisting of a horizontallydisposed semicircular chamber or casing` A, of refractory material, having perforations a and d', which extend through the top and sides thereof, the top and side Walls of said chamber being of a greater thickness at the end farthest from the gas-supply than the top and side walls adjacent thereto, substantially as shown, and for` thepurpose set forth. A

4. In an apparatus for burning natural gas, the combination, with a burner A, a lhead C, having a conical chamber and apertures e e, a gas-inlet pipe E, secured to the end of ksaid head, so thatthe end of the-gas-inletpipe eX- tends opposite the openings e e, and a rod =D, connecting the head C'to the opposite end of the burner, substantially as set forth.

In testimony whereof -I affix-my signature in presence of witnesses. l
