GAS-STOVE.

SPECIFICATION forming part of Letters Patent No. 651,160, dated June Application filed January 27, 1960. Serial No. 2,936. (No muriel.)

To all whom it may concern:

Be it known that I, PHILIP S. BRINDLE, a citizen of the United States, residing at Oolumbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Gas-Stoves, of which the following isa specification.

My invention relates to the improvement of gas-stoves; and the objects of myinvention are to provide an improved heating-stove of this character of superior construction and arrangement of parts, to so construct myimproved stove as to provide for the radiation of a comparatively-large volume or high degree of heat with the consumption. of a small amount of gas, to provide an improved construction of fines and arrangement and formation of the burner, and to produce other improvements the details of construction of which will be more fully pointed out hereinafter. These objects I accomplish in the mannerillustratedin the accompanying drawings, in which- Figure 1 is aviewin perspective of my improved stove. Fig. 2 is a central vertical section of the same, and Fig. 3 is atransverse section on line of Fig. 2.

Similar numerals refer to similar parts throughout the several views.

In carrying out my invention I employ a horizontal frame-like base portion 1, from the corners of which rise supporting-posts 2, which are preferably of an angular form in crosssection, as shown. These posts are surmounted by and serve to support a domelike top or cover 3 of suitable outline and which in the present instance is shown bowed forwardly and laterally, but provided with a vertical rear wall or back.

Depending from the upper portion' of the stove and from a plane or point at the base of the top plate 8 is a heat deiecting or radiating casing 4t, the latter having its ends and forward side tapering toward its lower end in the manner indicated in the drawings. The casing 4, formed as above described and as shown more clearly in Figs. 2 and 3 of the drawings, extends to the back wall or vertical back plate 6 of the stove-body, and adjoining the inner side of the latter I provide a vertical fine 7, which extends, as shown, to the base of the cap-plate or dome 3, and which in its upper portion is provided with a rearwardly-extending outlet 8. As vshown aty 9, the face and sides of the casinga are embraced by'an external jacket or casi ing the upperside of which is open and which forms, as shown more clearly in Fig. front and side communicating lues 10. The lower and forward portion of the iiue 10 has communicating therewith and extending rearwardly therefrom through the casing 4 to the i'lues 7 a pipe or flue 11. As indicated at 12, the outer faces of the jacket 9 are preferably covered with mineral wool or similar substance, the same material being employed on the exposed port-ion of the back plate 6 adjacent to the stove ends. 13 represents the burner of myimproved stove, which is of the well-known cylindridal form in cross-section and is provided with burner openings or perforations. It will be observed, however, that in constructing this cylindricalburner I produce the same of a substantially yoke form, the longer arm thereof extending in front of the lowerv portion of the heat-radiating jacket 9 and the shorter arms extending at right angles therewith along the sides of said jacket. The burner thus formed is suitably supported from a downward extension of said casing or jacket. 14- represents a horizontal yoke-shaped fender or filling plate the downturned outer edge of which is, as indicated more clearly in Fig. 2 of the drawings, supported in connection with the inner side of the frame 1 by engaging an inner-side socket or slot thereof. rlhe inner edge of this fender-plateis also downturned and termi nates at a slight distance from the burnerbody 13, result-ing in the formation of an airspace between the fen der-plate and the burner. The burner 13 is provided with the usual mixer projection 15, into which projects the gas-supply pipe 16. In constructing my improved stove I preferably form in the cap or dome-top 3 a desirable number of openings, one of which is indicated in Fig. 2 at 17. also preferably provide a desired number of these openings in the lower portion of the back plate 6, as indicated at 18.

In utilizing my improved stove the fiame which'ri'ses from the front and rearwardly-extending arms of the burner 13 is distributed over the wool or asbestos covered sides of the jacket 9, while the heat, burned gases, and other products of combustion passing up on the outer side of said jacket and following the direction of the arrows in Fig. 2 pass downward through the tlnes 10, thence through the lower transverse fine ll into the fine '7, and from the latter out through the opening 8. It will be observed in this connection that the products of combustion after descending between the side walls of the casing and jacket will be drawn to the front and passed out through the tlues l1 and 7, together with the similar products which pass downward through the front portion ot' the flue 10. As indicated by the dotted-line arrows, the air which enters the openings 1S and which passes upward from the bottom of the stove will pass about the flue 11, and thence upward through the casinget into the cap or dome 3, from which the air thus heated may pass outward through the openings 17. Owing to the employment ot' the tapering heater-casing and the fact that the burner, which is usually arranged across the front of a stove, is provided with rearwardly-extending arms, it will be seen that a largely-increased heat-radiating sur face is produced from a comparatively-small stove-body. It will also be observed that providing a space between the burner andthe fender-plate permits air to be drawn therethrough from below, which is immediately heated l'rom the burner.

Although I have shown myimproved stove with a flat or vertical back, it is obvious that the back and front might be constructed substan tially the same and that the burner might thus be carried across the back as well as the front and sides without altering the principles of my invention.

Owing to the provision ol a dome-like top or cap for the stove herein described it will be seen that an upper heat-chamber is produced which will greatly assist in the radiation of the heat in the room where the stove is employed.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a gas-stove, the combination with a horizontal base-frame, frame-standards rising therefrom and a convex top plate snri'nounting said standards, of inner and ou ter casing- sections 4 and 9 between which are formed the front and side communicating fines l0, a vertical flue-pipe '7 in the rear portion of said stove and a cross-pipe 1l connecting the same with said lue-pipe l0, a burner having one arm extending across the front portion of said stove, and end arms extending at right angles therewith across thel sides of said stove, substantially as specified.

2. In a gas-stove, the combination with a horizontal hase frame, frame-standards ris ing therefrom and a top plate surmounting said standards, of a easing having inwardlyinclined sides and ends,said easing supported between said top and base and having its upper termination at a point below the top plate, an outlet for said casing, a burner having one arm extending across the front portion of said stove and having arms extending at right angles therewith across the sides ot' the stove anda substantiallyyoke-shaped fenderplate adapted to fill the space between the burner an d base-frame,substantiallyas speci` fied.

PHILIP BRINDLE.
