.Application led November 18, 1896. Serial No. 612.557. (No model.)

.T all whom it nto/y concern.'

Be it known that I, PATRICK J. C Assnnv, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Gas-Stoves, of which the 'following is a specification.

My invention relates to the improvement of gas-stoves; and the objects of my invenro tion are to provide astove of this class adapted for the use of natural Vor artiiicial gases; to so construct and arrange the parts of my improved stove as to provide an increased radiation of heat without a corresponding increase in the volume of gas consumed; to so construct my improved stove as to provide for perfect combustion and to provide certain improvements in the construction and arrangement of the burner-plate, whereby an zo increased heating and radiation surface is produced, and to produce other improvements the details of construction of which will be more fully pointed out hereinafter. 4These objects I accomplish in the manner 2 5 illustrated in the accompanying drawings, in which- Figure lis a front elevation of my improved stove Fig. 2 is a side elevation of the same. Fig. 3 is a vertical section of said stove, and 3o Fig. 4 is a detail view in perspective of a portion of one of the burner-plate radiatingstrips.

Similar letters refer to similar parts through'- out the several views.

In the construction of my improved stove I provide a casing a, of sheet metal or other suitable material, said easing being provided with an open front which is provided with a suitable frame b. 4o vide a burner-plate c, which, as shown in the drawings, is inclined from a point in the upper and forward portion of said casing to a point in the rear and lower portion thereof. This burner-plate c is provided with a for- .45 ward projection c in its upper portion. The projection entends nearly to the front of the casing and forms an additional obstruction to the passage of the hot air and thereby causes more heat to be radiated into the 5o room. It also forms a hollow chamber within which the confined air is heated more quickly and escapes into the room.

Within ythe casing a l pro-' As indicated in the drawings, the upper portion of the casing above the burner-plate is provided with a horizontal liuc d, the latter communicating in its rear portion with a vertical ue e, which is adjacent to the back of the easing d. Between the iiue @,'inclined burner-plate c, and flue d is formed an airchamber f, which through the medium of the desired number of short vertical tubes f communicates with the interior of a top chamber g, which may be formed above the iiue d.

In case of the employment of the top chamber g I may form in the upper and transverse portion of the frame b suitably-arran ged perforations or outlets g.

At a suitable point below the iiue d the back iiue e is provided with an outlet e2, which may be made to communicate with a suitable pipe.

h represents separated transverse radiator and dame deiiecting strips, which, as indicated .in the drawings, are secured by rivets or otherwise one above the other to the outer face of the burner-plate. Each of these strips has formed therewith at desirable intervals outwardly extending and downwardly -inclined projections e', the latter preferably terminating in rolls, as indicated more clearly in Fig. e of the drawings. This construction and arrangement of the projections form inverted-V-shaped spaces between each projection and the plate, within which the ascending current of heated air is kept until it can force its way to the ends of the projections, which will retard its upward passage to a greater extent than if the attachments of the projections to the plate were smaller and did not extend in a horizontal direction across the plate. By inclining the plate forward it is evident that any air that might escape at the edge of these projections would ascend in a straight line and be caught in the projections above it, and thereby the passage of the air would be retarded and a larger amount of heat would be radiated into the room.

Through the sides of the casin g @are formed suitable openings awhich, as indicated, cono- Inunicate with the interior of the airchamber f.

In front of the lower end portion of the burner-plate c is supported a desirable form of gas-burner m, to which leads a suitable IOO
