TOP OVEN-PLATE FOR COOKING-STOVES.

Specification of Letters Patent.

Patented Sept. 17, 1907.

To all whom it may concern:

Be it known that I, JAFEW S. VAN BUREN, a citizen of the United States, residing at Albany, in the county of Albany and State of New York, have in vented certain new and useful Improvements in Top Oven-Plates for-.Gooking-Stoves; and I do hereby declarethe following to be a full, clear, 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.

My invention relates to improvements in cooking stoves and especially to the construction of the top plates of the ovens thereof.

The object of the invention is to prevent bulging or cracking of said top oven plates and also to facilitate the circulation of the heated air and the products of combustion whereby all parts of the oven are evenly heated.

The invention consists in the features of construc tion and combinations of parts hereinafter described and specified in the claims.

In the accompanying drawings, illustrating the preferred embodiment of my invention, Figure 1 is a perspective view of a top oven plate embodying my invention. Fig. 2 is a vertical cross-sectional view thereof taken through about the center of the bridge or arch. Fig. 3 is a longitudinal vertical sectional view taken centrally of said arch, and Fig. 4 is a broken perspective view looking into the oven, the

circulation of the heated air being illustrated by the arrows the relative positions of the fire pot and smoke flue also being shown.

Referring more particularly to the drawings, 1 designates the top oven plate which is formed of a single piece having a raised arch or bridge 2 extending longitudinally and centrally thereof. Said arch increases gradually in height from the end of the plate nearer the fire pot and its highest point is near the other end of said plate. From said highest point, the arch slopes abruptly to the level of the plate. In the upper portion of said abrupt slope is an opening 3 covered by a hood 4 secured to the arch and extending out nearly to the end of the plate.

By reference to Fig. 4 it will be seen that the highest portion of the arch or bridge extends up near to the top of the stove 'and thus serves to divide the products of combustion as they are discharged from the fire box and pass over the top of the oven, thereby The air passes out of this chamber through the opening 3 below the hood 2 which directs it down the end flue, as shown by the arrows in Fig. 4. The provision of the arch as a part of the integral top oven plate pre vents said plate from bulging or cracking by reason of any unusual expansion.

I claim:

1. In a cooking stove, the combination, with an oven, of a top plate for said. even having a longitudinal arch ex tending up near to the top plate of the stove and arranged between the vertical planes of the ends of said even, said arch gradually increasing in height in the direction of the rear end of the oven and constituting a division of the passage for the products of combustion formed be tween said plates whereby said even is evenly heated.

2. In a cooking stove, a top oven plate having an integral longitudinal arch extending up near to the top plate of the stove constituting a division of the passage for the products of combustion formed between said plates, said arch gradually increasing in height in the direction of the rear end of the oven and having means at its higher end for ventilating said even.

' In a cooking stove, the combination, with the bottom, side and end walls of the oven, and means to supply heated air to said oven, of the top oven'plate having a longitudinal chambered arch provided with an opening in the rear end thereof, and a hood arranged over said opening and extending in the direction of the flow of the gases for the purpose specified.

4. In a cooking stove, the combination, with the bottom, side and end walls of the oven, and means to supply heated air to said oven, of the top oven plate having a longitudinal chambered arch which increases in height from its end nearest the lire box to near the other end thereof, and thence sloping abruptly to the level of the plate, said arch provided with an opening near the top of said abrupt slope, and a hood arranged over said opening and extend ing in the direction of the flow of the gases for the purpose specified.

In testimony whereof, I aflix my signature, in presence two witnesses.

JAFEW S. VAN BUREN.

Witnesses A. I. I-IENNESSY, H. S. NELSON.
