The air outside of the inner stove enters at the bottom of the range and passes along the sides I! in contact with the heated walls 3| of the inner stove. The air then passes out of openings 20 at the top of the range and side openings 2|.

While in the foregoing illustrated description I have set forth a. specific preferred structure, it will be understood that considerable variation may be made in the details of construction without departing from the spirit of my invention.

The foregoing detailed description has been given for cleamess oi understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible, in view of the prior art.

I claim:

1. In a stove, a casing providing a firebox, an ash drawer compartment therebelow and a bottom closed except as to its forward end portion, said forward end portion being provided with an air inlet, means for controlling said inlet, means cooperating with the sidewalls of said drawer compartment to provide with said casing vertical passages in the front portion of the casing communicating with said bottom air inlet, an outlet flue communicating with the rear portion of the firebox, an ash drawer in said compartment, and downwardly inclined spreader guides carried by said casing and extending over said air passages, said guides extending substantially the length of said firebox, and being adapted to direct ashes into said drawer and spread the rising air from said passages inwardly and rearwardly below said firebox.

2. In a stove, a casing providing a firebox, an ash drawer compartment therebelow and a bottom closed except as to its forward end portion, said forward end portion being provided with an air inlet, a slide mounted in said casing for controlling said inlet, a lever having its extreme rear end portion pivoted to the bottom casing wall and an intermediate portion pivotally connected to said slide, the forward free end portion of said lever extending to the front of said stove, an outlet flue communicating with the rear of said firebox, means cooperating with the sidewalls of said drawer compartment to provide with said casing vertical passages in the front portion of the casing communicating with said bottom air inlet, an wh drawer in'said compartment, and downwardly inclined spreader guides carried by said casing and extending below and the length of said firebox, said guides being adapted to direct ashes into said drawer and spread the rising air inwardly and to the rear of said vertical air passages.
