GAS-OVEN.-

Specificationof Letters Patent.

Patented April 17,1906.

Application filed December 26, 1903. Serial No. 186,634.

tains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

,This invention relates to igniting devices for gas-ovens. In'this kind of oven the gasflame is inclosed within the oven itself; and the object of my invention is to provide 'an improved device whereby the gas ma be ignited from the outside of the oven an at the side thereof and in which danger from explosion. of a gas and .air mixture within the oven is avoided;

I am aware that patents, numbered 698,009 and 698,010, were granted to G. W. Graves and to this inventor and J. F. Mills, J r., April 22, 1902. In these patents devices are shown in which it is necessary to put the igniting flame within the oven from a position in front of the open door. There is danger in such devices of causing an explosion which may injure the person igniting the gas.

M invention consists in the improvements hereinafter described, and pointed out in the claims.

Referring to'the accompanying drawings,

Figure 1 is a perspective view of an oven of the type to which the device of this inven- Fig. 2 isv a plan view showing the foraminous tubes or manifolds which to be burned as it issues in'jets through the holes in said tubes together with the device for igniting the jets from the outside of the tube. Fig. 3 is a detail section on the line 3 '3. of Fig.2. Fig. 4 is an elevation of the parts shown in plan in Fig. 2. Fig, 5-

is 'a perspective view of the a aratus for lgniting the jets from the outsi e of the oven.

Fig. 6 is a sectional perspective view of the part of the apparatus of Fig. 5 contiguous to a wall of the oven adjacent thereto.

A A are walls of the oven. B is the door of the oven proper, which door in this case is shown as of the drop kind.

C is a door ldading to a chamber below the and a portion of. the walls her are the tubes ormanlfolds D D".

cock controlling the "admission of gas to the tube or manifold D.

E is the device for igniting the jets from the outside of the oven. This consists of two castings united together by a bolt e to form a T-shaped conduit or trunk, two ends of which partially surround the tubes or manifolds D D. The portion between the tubes D D is arched upward to a point intermediate between said tubes-and from themiddle portion extending upward and outward there ertu're a through the Walls of the oven. The upper casting of the device shown in Fig. 5 has formed in it the notches E at the edge. which comes against the lower casting at the inner side thereof, or holes may be drilled in other parts-of the trunk, so that said notches rihamber'in said device which extends be-. tween the tubes D D. Holes through the walls. of the tu'besD D (shown most distinctly ber of the'devic'e E, which extends between the tubes D D, so that a gas-jet'is projected into said chamber toward the tube E" from said holes. Since the hole a at the outer it is generally desirable to have some such covering member as the lever F, which is pivoted at f to the side of the oven and may be used as a closure over the hole a when the oven is not in use to render impossible ignition from the flame of a match unintentionally and carelessly held near the'opening.

The operation of the above-described device is as follows: The cock D or D or both of said cocks, are 0 ened, admitting a jet of as from the pipes into 1 the pipes or manioldsD D. These jets carry with them a small portion of air, but not sufficient to make a combustible mixture. The gas forced into the'manifolds D D flows out of the holes d into the chamber between said manifolds in the device E, and the gas rises up in the conduit E to the aperture 0. in the oven-wall and may be lighted by a match at said aperture from the outside of the oven. Air flows in throu h the notches E to mingle with the. as, maIring a combustible mixture. The

ame is carried down the tube E through the in Fig. 3and marked (1) open into the cham end of the tube E is in a side wall of the oven,

. oven proper, at the upperpart of whichchaml I D is a cock controlling the adnnssion gas to the tube or manifold D, and D is-a is a part E formmg a tube leading to anapform openings leading into the channel or.

channel or chamber between the manifolds D D., and the jets of said manifolds are ignited by said flame. It will be observed that the tube E has its upper end contiguous to the inner walls of the oven, its channel communicating' with the oven through an aperture. Thus theh'ot air passing throughthe tube E is carriedintp the oven and not to the outside of the oven. If one burner is lighted, it will ignite the asflowing into the trunk E, and the flame Wlll be carried from the lighted burner toignite the opposite burner.

What I claim is 1. The combination of two burners, a lighter adjacent to said burners and adapted to catch 'escapin gas from each of said burners, said lighter icing provided With a trunk extending between the burners, said trunk being provided With'a series of'perforations extending through its Walls throughoutits length to admit air to every part of the length of the gas-column in said trunk.

2. The combination of a burner having an aperture therein to permit the escape of a jet of (gas therefrom, a trunk open at each end an having its open end located adjacent to said burner and in front of the aperture therein, said trunk being provided with a series of perforations extend ng through its walls throughout its length ada ted to admit air to every part of the length 0 the gas-column in said trunk to form a combustible mixture therewith.

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

THOMAS E. TAYLOR.
