GAS-BURNER.

Specification of Letters Patent.

Patented Oct. 28, 1913.

Application filed February 3, 1913. Serial No. 746,011.

To all whom it may concern:

Be it known that I, CHARLES HOWARD HOOK, a citizen of the United States of America, residing at Pittsburgh, in the county of Alleghen and State of Pennsylvania, have invente certain new and useful Improvements in Gas-Burners, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to gas burners, and my invention aims to provide :First, a burner wherein natural, artificial or other gases can be used as a fuel and heating medium to produce a high temperature in connection wth a stove, furnace, steam or hot water boiler, gas boiler, air heater and other structures to which a burner in accordance with my invention is applicable. Second, a new article of manufacture in the form of a burner practically in one piece and consequently inexpensive to manufacture, and of such construction as to place it upon a commercial basis. Third, a longitudinal or circular burner wherein positiveand reliable means are resorted to to insure an equal distribution of gas throughout the burner and to obtain a high temperature with a minimum expenditure of fuel.

I attain the above objects by a mechanical construction that will be hereinafter specifically described and then claimed, and refer ence will now be had to the drawings, wherein:

Figure l is a perspective view of a burner in accordance with this invention, Fig. 2 is a plan of the same partly broken away, Fig. 3 is a view of one end of the burner, Fig. 4 is a view of the opposite end of the burner, Fig. 5 is a perspective view of one end of the burner with an end plate thereof removed, Fig. 6 is a perspective view of the removed end plate, Fig. 7 is a longitudinal sectional view of the burner partly broken away and partly in section, Flg. 8 is an enlarged cross sectional view of a portion of the burner, illustrating the formation of a flame, Fig. 9 is a plan of a burner designed for furnaces and other structures. Fig. 10 is an enlarged cross sectional view of a single piece burner. Fig. 11 is a similar View illustrating a slight modification, and Fig. 12 is a plan of another burner designed for furnaces and other structures.

A burner in accordance with this invention comprises a casing that tapers from the inlet or inner end thereof to the outer end, the taper of said casing being essential in order to insure an equal distribution of gas at the outlet openings of the burner. The casing is composed of parallel side walls 130 connected by an integral rounded and tapering bottom wall 2, which at the inlet end of the burner merges into a cylindrical connection 3, the inner walls of which are screw threaded, as best shown in Figs. 5 and 7.

The parallel walls 1 are formed integral with an inverted V-shaped top plate 4 and at the oute'rend of the burner the walls 1 and the top and bottom plates 4 and 2 are formed integral with a bracket 5 that has an angularly disposed web or brace 6. and provision for a fastening means, whereby it can be secured to a suitable support or structure, should occasion require. The in let end of the burner, above the connection 3 is open, as shown in Fig. 5 and this open end is adapted to be closed by an end plate 7 held in position by a screw 8 or other fastoning means. In some instances the end plate 7 can be brazed, soldered or otherwise connected to the inner end of the burner casing, While in other instances, as will hereinafter appear, the end plate 7 can be made integral with the burner casing, whereby the casing can be produced by a minimum number of operations, and consequently reduce the expense of manufacture.

The top plate 4 of the burner casing has the apex thereof provided with vertically disposed equally spaced outlet openings or ports 9 and the inclined sides of this top plate have equally spaced outlet openings or ports 10 that are preferably staggeredly arranged relatively to the openings 9. The openings 10 form two rows with the openings 9 forming an intcrmediate'row and for a successful operation of the burner the openings 9 are essential for the following reason. If the openings 9 were not used the gas emitted from the openings 10 and con- 100 sequently the flame thereof would be projected in the direction of the dot and dash lines, Fig. 8. By employing the openings 9 the gas emitted therefrom produces a suction or vacuum that draws'the flames of 105 gas from the openings 10 toward the central flame of gas from the openings 9, the three flames converging as shown in Fig. 8. In consequence of the arrangement of the openings 9 and 10 the flame from the burner can 110 be projected and located at a desired point for accomplishing a desired result which is essential particularly in connection with a narrow heater, such as disclosed in my pending application, Serial Number 7 25,187 filed October 11, 1912.

As heretofore stated, the end plate 7 is detachable and this end plate permits of easy access being had to the burner casing in order to install a longitudinal screen 11, which is arranged between longitudinal parallel retaining ribs 12, carried by the inner sides of the Walls 1, adjacent to the top plate 4:- This screen is employed to retard gas, and to insure a proper mixture and distribution, but I desire it to be understood that the use of this screen is not essential, as by actual practice I have found that with certain gases the same, if not better, results are obtained by the burner by not using the screen. In such instances, the end wall 7 can be cast integral with the burner casing and consequently reduce the expense of manufacture and eliminate all danger of leakage due to this separate element.

In Fig. 11 of the drawings I have illustrated the openings 10 as being vertical instead of angularly disposed, as in Fig. 8 and in either instance the same result is obtained, only the operation of drilling the openings 10 at an angle is more easily performed than by drilling them vertical, as shown in Fig. 11. p

In Figs. 9 and 12 of the drawings, I have illustrated the principle of my invention as embodied in a circular and rectangular burner, made in two parts, such burners being applicable to large furnaces used for various purposes. These forms have simply been illustrated as an example of other forms or configurations that might be resorted to according to the structure in connection with which the burner is to be used.

While in the drawings there are illustrated the preferred embodiments of my invention, it is to be understood that the structural elements are susceptible to such variaowers tions and modifications as fall within the scope of the appended claims.

lVhat I claim is 1. A gas burner comprising an elongated tapering casing having the large end thereof provided with a gas inlet connection, and an inverted V-shaped top plate forming the top of said casing and having rows of gas outlet openings formed therein wit one row of openings disposed relatively to the other rows of openings for producing a suction when gas is emitted from said openings.

2. A gas burner comprising a tapering casing, an inverted V-shaped top plate forming the top of said casing and provided with gas outlet openings, a screen arranged within said casing beneath said openings, and an end plate detachably connected to said casing whereby easy access can be had to the interior of said casing for placing said screen therein.

3. As a new article of manufacture, a gas burner made of a single piece of material and embodying a casing having a V-shaped top formed with rows of gas outlet openings, one row of openings disposed relatively to the other rows of openings for producing a suction when gas is emitted from said openings, one end of said casing being closed, the other end provided with an opening and a gas inlet connection below said opening, and a removable plate for closing the said end opening.

i. A gas burner comprising a casing having a V-shaped top, one end of said casing being larger than the other, means for closing said smaller end, a removable closure for said larger end, and a gas inlet connection projecting from said larger end and below said removable closure.

In testimony whereof I affix my signature in the presence of two witnesses.
