COMBINED GAS AND FUE L STOVE.

SPECIFICATION forming part of Letters Patent No. 617,362, dated January 10, 1899.

Application filed November 9, 1897. Serial No. 657,966. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHARLES D. SHEPARD, a citizen of the United States, and a resident of Peekskill, in the county of Westchester and State of New York, have invented certain new and useful Improvements in a Combined Gas and Fuel Stove, of which the following is a specification.

This invention relates to cooking stoves and ranges, and has for its object an efificient means of heating the oven with gas without the handling of gas-burners, the burner being a fixture in the oven and while not interfering with the ordinary use of the oven with fuel heat is always ready for the application of gas heat. The object is attained by the means set forth in the accompanying drawings, which when taken with this specification constitute a full and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. Referring to the drawings, Figure I is perspective View of a stove-oven and its surrounding flues, represented as having part of the front plate removed. Fig. II represents the end of the stove with front plate removed, showing the end of the oven and the damper d for use when the stove is to be heated with fuel. Fig. III is an elevation of the stoveoven, fines, and gas-burner in cross-section through the center of the oven. Fig. IV is a top view of the end of the stove, representing the top plate of the stove removed and showing the damper and gas-burner connections. Fig. V is an end view of the gas-burner, partly in section. Fig. VI represents a section of the oven-door, showing a register for admitting air to the gas-burning chamber when the oven is heated with gas.

Reference to Fig. I will disclose the main features of the invention. The end of a stove containing an oven and its surrounding flues is shown, 3 indicating the fire-box and 4 the ash-pit. a represents the stove-oven, with the usual flues on three sides of itz'. 6., the flue 6 between the top plate 25 of the stove and the top plate 0 of the oven, the end flue Z, and the bottom flue m. The arrows 1 l 1 1' show the course of the products of combustion to be from the fire-chamber 3, over the top of the oven through flue 6, down at the end of the oven through flue Z, under the oven through flue m, where the partition "Z deflects them to the front of the flue m, whence they pass to the outlet-flue j to the chimney.

In the upper corner of the oven holes hare cut through the end plate of the oven to the flue Z, and these holes are covered by a damper d. The openings are bordered, preferably, on the flue side with inclined flanges 0, Figs. II and III, so that the damper-will the more readily close by its own weight when it is intended to be kept closed upon the openings. It is a mere matter of convenience whether these outlets from the oven to the flue should consist of two openings or of only one, or more than two. The damper d is hinged above the openings, as shown, and is adapted to not only close the openings, as shown in Fig. II, but when the gas-burner is in use and the holes h are to be open the damper closes the flue Z above the holes, as shown in Figs. II and III.

A gas-burner 6, Figs. I, II, and III, is affixed to the top plate of the oven. A righthand end View of the burner, as is herein shown, to be used is represented by Fig. V. It has a corrugated under surface, the apex of the corrugations being pierced with small gasoutlets, as shown at 6, Fig. III. A nozzle f, Figs. I and III, for the attachment of a gaspipe is integral with the burner. A pipe extension passes from the burner through the flue Z to the outside of the stove, where the air-supply s and gas-cock u are applied, as in Figs. II and IV. The particular construction of the burner, however, is immaterial. It is only important that the gas-flames be distributed uniformly over the top of the oven.

As shown in the several figures, the burnerpipe passes through the flue Z below the point where the damper dis hinged, which involves the notching of the damper around the pipes, as shown at y, Fig. IV.

The damper d is provided with a handle g,

extending through the outer stove-plate. As represented, it has a weighted handle '11 to serve as a counterbalance to the weight of the damper and keep it close to the outer flueplate when in the position indicated by the broken lines g 9, Fig. II.

A baffle-plate b is inserted in the oven just below the openings h, supported on lugs y.

The end of the plate opposite the openings is perforated, as at 7t, Figs. I and III, for the escape ofgases from the part of the oven below the plate. The oven-door at the corner corresponding with the perforations in the said baffle-plate is provided with a register or any convenient equivalent, as indicated in Fig. VI, for the purpose of admitting air to support combustion in the bu rner-chamber.

Then the oven is to be heated by means of the gas-burner, the damper (Z is placed in the position shown in Figs. I and III, cutting off flue 6 from the flue Z. The gas-flames shooting downward from the burner 6 will heat the baffle-plate, and the heated currents from the chamber above the plate will pass into the flue Z from the openings 71 thence to the flue m under the oven, and out through the fluej to the chimney, heating the oven on the top, end, and the bottom. As the burner is made to cover the top plate of the oven, little loss of heat takes place through the said top plate.

I do not wish to be limited to any of the constructions as herein shown and described so long as I adhere to the principles of this invention.

Having described my invention, what 1 claim, and desire to secure by Letters Patent of the United States, is-

1. The combination in a stove provided with an oven and a direct flue from the firebox of the stove over the top of the oven, down the side of and under the oven to the outlet-flue, of a gas-burner placed in the top of the oven, a bathe-plate supported in the oven beneath the burner, the space between the burner and baffle -plate provided with openings extending through the side wall of the oven communicating with the flue at the side of the oven, and a damper that may be used to close said openings when the gasburner is not in use and to open said openings and close the side flue above said openings when the gas-burner is in use, substantially as herein shown and described.

2. The combination in a stove having an oven and a direct fine from the fire-box over the top of the oven, down the side of and under the oven to the outlet-flue, of a gasburner placed in the top of the oven, a perforated baffle-plate beneath the burner, the space between the burner and baffle-plate provided with openings extending through the side wall of the oven communicating with the flue at the side of the oven, and a damper that may be used to close said openings when the gas-burner is notin use and to open said openings and close the said flue when the gas-burner is in use, substantially as herein shown and described.

3. The combination in a stove having an oven and a direct flue from the fire-box over the top of the oven, down the side of and under the oven to the outlet-flue, of a gasburner placed in the top of the oven, a perforated baffle-plate supported in the oven beneath the burner, the space between the burner and bathe-plate provided with openings through the side wall of the oven communicating with the flue at the side of the oven, a damper that may be used to close said openings, or to open said openings and close the flue on that side of the said openings which is toward the fire-box, and an airinlet in the oven-door, substantially as herein shown and described.

Signed at Peekskill, in the countyof W'estchester and State of New York, this 21st day of October, A. D. 1897.

CHARLES D. SHEPARD.
