DAVID B. COX, OF TROY, NE'W YORK, ASSIGNOR TO HIMSLF AND HAR- VEY CHURCH, OF SAME PLACE.

IMPROVED STOVE.

Specification forming part of Letters Patent No. 45,478, dated December 20, 1864.

To all whom it may concern Be it known that I, DAVID B. Cox, of the city of Troy, in the county ot' Rensselaer and State of New York, have invented new and usetul Improvements in Cooking and Parlor CoatBurning Stoves; land that I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and specifications- Figure l being a vertical section of the stove, showing the inner arrangement. Fig. 2 shows outside face of a section of irepot. Fie. 3 shows inside face of same section.

Like charaetersindicate like parts in all the drawings.

The space A is the ash-chamber, into which airis admitted through the door I and passed up through the grate at the top of ash-chamber, to support combustion in the tire-chamber H. The fire-potis constructed ot' iron, or may be ot' other material, in one piece, or in sections, with horizontal corrugations, and set into an incasement, J J, leavinga large chamber, B B B B, from top to bottom of re-pot, into which airis admitted atintervals around the bottom at K K, filling the Whole chamber, from which it passes, in a higlily-heated state, through the apertures C C C into the tire-pot in such quantities as to not only aid combustion ot' the fuel on the sides otl tire-pot but to commingle with the inammable gases and consume their carbon, so that no soot will escape into the exit-pipe and chimney from the burning of bituminous or other coals.

It will be observed that the inner projections of the corrugations at D form a protection or guard to the apertures C C C, by which coals or ashes are prevented from stopping them up or from falling through to the outside ot' tire-pot. The position ot' these aper tures C C C in the corrugated plate or plates and the manner ot' Working them through enable me to mold them in sand and cast them without ditiiculty.

The sections or staves may be made on a circle and suited to a rou-nd or oval fire-pot, or the57 mayas readily be made to suit a square or an oblong lire-pot.

Of the corrugations, they may be made in any practical number. p

l do not broadly claim a perforated tire-pot or plate, but

I do claim- 4 l. In a horizontally-corrugated repot, or plate or plates, forming part or the whole ot' a tire-pot, the apertures C C C, when placed in that part of the corrugat-ion inclining from the center or ire to the outside at such point as will leave the extreme inner projection of corrugation projecting over said apertures, forming a cover or guard for them for the purposes described.

2. In combination with said corrugations and apertures, the air-chamber B B B B, for the purposes described.

DAVID B. COX.
