JOHN T. BUDD, OF NEW YORK, N. Y.

HOT-AIR FURNACE.

Specification forming part ofLetters Patent No. 58,373, dated October 2, 1866.

To all lwhom t may concern:

Beit known that I, JOHN T. BUDD, of the city and State of New York, have invented and made a certain Improvementin Hot-Air Furnaces; and I do hereby declare the following to be a full, clear, a-nd exact description of the same, reference being had to the annexed drawings, making part of this specilication, wherein* j Figure lis a vertical section of my improved furnace, and Fig. 2 is an exterior perspective view of the same.. g

Similar marks of reference denote the same parts. j

The object of my invention is to convey a regulated supply of heated air tothe re at or near the top of the fue] toA promote a perfect combustion. To effect this I employ a casing surrounding the firepot, with openin gs into the tire-chamber, and with a register or door to regulate the admission of air; and I employ radiatingpipes at the sides of the furnace to increase the heating-surface.

In the drawings, a represents the ash-pit; b, the re-pot; c, the fuel slide and door; and d, a dome over the tire, from which apipe, `c, and damper for kindling passes to the chimney.

On each side of the dome d I place radiating-tubes f, running back and forth, and terminating in a lateral connection, g, to the tube e. These radiators j' increase the heatingsurface, aud they may be tted with Openings and covers inthe elbows for cleaning.

Around the lire-pot b is an air jacket or cas* ing, h, having holes in its upper surface below a perforated shield, la, which is near the level of the top of the fuel in the fire-pot b, and

said shield, being perforated with numerous small holes, a supply of air is allowed to pass in above the fire for consuming the gases and rendering the combustion more perfect. The air becomes highly heated by contact with the exterior of the re-pot, and hence is adapted to promote combustion.

The admission of air to the jacket hinay be regulated by a door or register at i, and, it' desired, a thorough ventilation of apartments v may be effec-ted by a descending pipe leading from such apartments and connecting with the air-jacket h.

By 4the air-jacket surrounding the tire-pot and conveying its heat into the furnace itself, the dryness of atmosphere experienced from the red-hot re-pot is prevented., and at the same time no heat is lost, as the temperature of the entire furnace is increased by the hot air carried into it from the jacket.

What I claim, and desire to secure by Letters Patent, is-

1. The dome d, pipe c, and damper, in combination with the two ranges of return-pipes f at the sides of the furnace, connected to the pipe e by the lateral connections g, as and for the purposes set forth. j

2. The air-jacket 71 surrounding the lire-pot, in combination with the shield k, for allowing a regulated quant-ity ot' heated atmosphere to pass into the gases above the lire for their consumption, as set forth.

Dated this 21st day of May, A.. D. 1866.

JOHN T. BUDD.
