UNITED STATES PATENT OFFICE,

GEORGE R. MOON, OF WILMINGTON, OHIO.

OVEN.

SPECIFICATION forming part of Letters Patent No. 476,291, dated June 7, 1892.

Application filed September 29, 1891. Serial No. 407,113. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE E. MOON, a citizen of the United States, residing at Wilmington, in the county of Clinton and State of Ohio, have invented certain new and useful Improvements in Ovens; and I do hereby declare the 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.

The invention consists in certain improvements of that kind of ovens described in Letters Patent No. 415,649, issued Novemberlfl, 1889, such ovens being provided with heatcqualizers for conducting the heat to the side walls of the oven.

111 the accompanying drawings, Figure 1 represents a vertical section of an oven with an equalizer and provided with my improvements. Fig. 2 is a section taken on line a: 00 of Fig. 1. r

A designates the casing of the oven, and B indicates a heat-equalizer placed in said oven in position to receive the heat directly from the flame or burner. The said equalizer contains tlues, which extend in opposite directions and are inclined somewhat upward, as shown. The lines ct receive the heat directly from the burner and conduct it to the side walls of the oven, and the fines c serve as radiators and to conduct air that may enter through the aperture 6 in the side wall of the equalizer and become heated to the side walls of the oven.

The oven is provided with shelves d, which are made solid, to serve as deflectors of heat. Openings h are made in said shelves at their ends or sides next to the walls of the oven and above the passages from the flues of the equalizer, so that the heat maypass from the equalizer into the compartments over the shelves, respectively, and be deflected by the upper shelf and by the top plate of the oven. At the extremities of the upper shelf are placed the sliding plates m, which extend along the openings and are supported in grooves or on cleats n, the said plates being movable thereon. By means of the plates at the upper compartment of the oven may be closed and the heat shut off therefrom when only the lower compartment and shelf are to be used.

The oven may be provided with more than one upper shelf having openings with closingplates m, as may be found desirable.

I claim- The combination, with an oven-equalizer 13, having flues a c, of the shelves (1, coming short of the walls, and the slides h, as and for the purpose set forth.

In testimony whereof I have affixed my signature in presence of two witnesses.

GEORGE R. MOON.
