GAS-STOVE.

SPECIFICATION forming part of Letters Patent No. 670,850, dated March 26, 1901.

Application filed July 31, 1899. Serial No. 725,566. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD J.DASOHBACH, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Gas-Stoves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a front elevation, partly broken away, of my improved gas-stove. Fig. 2 is a vertical cross-section of the same. Fig. 3 .is a horizontal cross-section on the line III III of Fig. 2. Fig. 4 is a rear view, partly broken away, showing a modified form. Fig. 5 is an end view, partly broken away, of the stove of Fig. 4. Fig. 6 is a perspective detail view showing the supporting-lug for the fender, and Fig. 7 is a detail View of a modified form of deflectouplate.

My invention relates to gasstoves, and more particularly to those in which a baseburner is employed, with a vertically-extending fire-board along which the flames and gases rise, though certain features are applicable to other forms of stoves; and the object of the invention is to cheapen the construction of such stoves and make them more economical and efficient.

In the drawings, referring to the form of Figs. 1, 2, and 3, the stove-body is formed with a back 2, of sheet metal, and sides 3 3 are secured to the back by seams 4 at the rear corners of the stove. The front panels 5 5 are formed integrally with the sides 3, and the ornamental front panels 6 6 are provided with lips 7, engaging the edges of the panels 5, the cheeks 8 being formed integrally with the ornamental panels 6. The hollow base 9 is provided with an inner rear flange 10, which is bolted through the front panels 5, and with an upper horizontal flange 11, which extends across the front of the stove and is secured by screw-bolts 12, which extend through the panels 5 and 6, the ends of the flange 11 extending between these panels at each side.

To support the fender 13, I cut from the lower end of the cheeks short strips, which are bent into the lugs 14, (shown in Fig. 6,) these lugs having depending flanges 15 to prevent tilting of the fender, which is bent outwardly to form a rib 16, the end portions of which rest upon and are supported by the lugs 14. The upper portion of the fender rests upon the burner 17, which consists of a hollow box formed of sheet metal and preferably in the form of a parallelepipedon, the box being carried upon straps 18, secured to braces 19, bolted to the sides of the stove.

The fire-board 20 is curved or bent forwardly, so as to present a convex front face, and the burner-box is provided with a curved series of perforations, as shown in Fig. 3, so that the jets of flame will play over the front face of the fire-board, which is provided with the usual asbestos covering, as shown. The fire-board is fastened to the sides by flanges 21, secured by rivets, these flanges lying between the sides and the inner parts of the cheeks, so as to be hidden by the cheeks. The space between the lower end of the fireboard and the back is closed by a plate 22, secured to the fireboard and having depending flanges on the sides and back, which are riveted to the sides and back of the stove, respectively. The top of the stove is closed by an inner cover 23, which inclines forwardly and downwardly and is secured by flanges riveted to the sides and back, and over this cover is an ornamental top 24, having a rear flange 25, which embraces a flange projecting rearwardly from the back of the stove and is secured by screw-bolts 26, extending through the panels 5 and 6. The top of the fire-board extends to within a short distance of the inner cover 23, and between the fireboard and the back is secured a box 27, having an open top and bottom, the top extending very nearly to the false cover 23, so as to allow a small proportion of the products of combustion to pass directly to the outletflue 28, while the major portion of these products pass downwardly around the box and thence up through it to the outlet-flue. I thus obtain a circuitous course for the gases within the stove structure itself, thus increasing its heating power. The mixture of gas and air is supplied to the burner through any suitable mixer 29, projecting into the burnerbox, and the burner-box is provided with a diagonal deflector-plate 30, having flanges which engage the angular corners and hold it in place, this plate extending through the intermediate part of the boX above the mixer.

In Figs. 4 and 5 I show a modified form of the baffle-plate. In this form, instead of the box shown in Figs. 1, 2, and 3, I employ a plate 31, which extends from side to side in the rear of the fire-board and is provided with perforations 32 in its upper portion, through which a small portion of the products pass direct to the chimney, while the major portion pass down and around the plate. In Fig. 7 I show another form of deflector consisting ,of a horizontal plate 33, having upward and downward flanges 34, engaging the inner corners of the box.

The advantages of the invention result from the cheapness and strength of the stove structure, the parts being easy to make and assemble, and from the economy of gas and enlarged heating power. I believe I am the first to employ a forwardly-cu rved fire-board with a correspondingly-curved base-burner, and this gives several advantages, among which is that a slight warping of the board will not throw it out of proper line with the jets, as in the case of a fiat fire-board having a base-burner.

Many changes may be made in the form and arrangement of the parts without departing from my invention, since I claim- If A gas-stove, having a forwardly-curved upright fire-board and a correspondinglycurved base-burner therefor; substantially asdescribed.

2. In a gas-stove, a burner consisting of an angular box, having a curved series of perforations in its flat top, and a correspondingly curved fire board along which the flames and products rise; substantially as de scribed.

3. A gas-stove, having an upright fire-board, and a baffle-plate between the fire-board and the back of the stove, and constructed and arranged to allow a portion of the products to pass direct to the outlet-flue, while the remainder pass around the plate, the fire-board forming the front of the chamber containing the baffle-plate; substantially as described.

4:. A burner consisting of an angular sheetmetal boX having a flat top and containing a deflector provided with flanges engaging the angular corners of the box; substantially as described.

In testimony whereof I have hereunto set my hand.
