SPECIFICATION forming part of Letters Patent No. 597,349, dated January 11, 1898.

Application filed August 9, 1895.

To CLZZ whom it may concern:

Be it known that I, J noon ALBRIGHT, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Broilers; and I deolarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to gas-burning broilers, and has for its object an improvement in that class of broilers in which the article to be cooked is exposed between two plates or burners over which are scattered a large number of small gas-jets, thus producing a sheet of flame parallel to the side of the article.

This invention relates to the proper conveyance of gas from the main to the burner or jet holes, to the material employed as the plate perforated for burner or jet holes, and to provision for a second supply of airin addition to that received at the mixer for the proper combustion of the gas.

Broilers of this class are usually arranged with the burner-plates vertical-that is, the burner-jets are scattered over two of the vertical walls and are directed inward. A supply of air from the bottom of the case passing upward along the burners affords sufficient oxygen for a few of the jets along the bottom of the plate, but is soon deprived of oxygen and charged with products of coinbustion, so that the upper jets of flame do not get a sufficient supply and burn poorly.

Another improvement relates to the material through which the jet-holes are made.

The jet-holes are small, and when iron or brass is used they quickly fill up with a deposit. Epecially is this so where natural gas is used as a fuel, and I have found that by using thick asbestos board instead of metal the holes will remain clear for a long period of time.

In the drawings, Figure 1 is a front elevation. Fig. 2 shows the burner-plate, a portion only of the plate being shown. Fig. 3 is asectional elevation across the broilers,

fierial No. 558,748. (No model.)

the section being taken across the broiler at line :0 w of Fig. 4. Fig. 4 is a side elevation, a part only of one side being shown.

The broiler is made in a substantially rectangular box or stove, with a base A and cap plate B, provided with an outlet 6 for the es cape of products of combustion, the outlet having a collar (7, upon which to seat a pipe, if desired. The bottom is preferably closed by a sheet of thin metal a, and one of the ends or narrow sides is closed by folding doors C 0, provided at their meeting edges with openings 0 0, through which the handle of a grid can project. Provision is made at the bottom for a drip-pan D.

The sides 2 2 of the broiler contain the main features of the invention. They are exactly alike except that one is a right and the other a left side. The side 2 is made with connections, so that on the outside it takes the form of a vertical halfpipe 8, into which leads an inlet 4 and out of which lead a number of horizontal half-pipes or fingers 5 5 on the inside of the plate 2. The upright half-pipe and fingers are concave, and they are united by the main plate, which forms a web between adjacent fingers 5. The inner faces of these webs and the inner-face of that part of the plate which surrounds the upright and fingers are all in one plane, the whole plate being surrounded by proper engaging grooves and flanges, by means which the several plates constituting the structure can be securely held together by concealed bolts. The upright half-pipe at the bottom has an inlet 4, which is completely tubular in form and is adapted to receive and hold the mixer-mouth this being any approved form of mixer adapted to mingle air and gas. The tubular structure of the upright 3 and fingers 5 is completed by a sheet of asbestos held in any suitable way, as by bolts 8 S 8, to the plate 2, and engaging closely with the inner face of the plate and with the inner faces of the web portions of the plate between the fingers 5 5.- Along the inner plate are rows of jet-holes 9 9, which perforate the inner plate and enter the tubular cavities 1O 10 under the fingers 5. Between the fingers 5 5, through both the Web and the inner plate, are air-inlet openings 12 12. Across the inner plate and just above the gas-jet openings 9 9 are rows of fibrous asbestos held to the inner plate by cement or in any other suitable Way. These layers of fibrous asbestos would tend to prevent a free access of secondary air from below, and

corrugations and against the web, said web being perforated and said plate being provided with perforations registering with the perforations through the Web and with gasjet perforations leading through the plate into the tubular cavity formed by the corrugation and plate.

2. In a burner for broilers, the combination of a tubular gas-conductor perforated with gas-jet openings, air-inlet openings arranged beneath the jet-openings and a layer of asbestos fiber disposed above the openings, substantially as described.

In testimony whereof I sign this specification in the presence of two Witnesses.

JACOB ALBRIGHT.
