: i I v ER f @ttm witmsz /y/ i UNITED STATES PATENT OFFICE.
WILMOT W. DODGE, OF BOSTON, MASSACHUSETTS.
IMPROVEMENT IN HOT-AIR FU'RNACES.
Specification forming part of Letters Patent No. 130,847, dated August 27, 1872.
Specification describing a new and useful Improvement in Hot-Air Furnaces, invented by WiLMoT W. DODGE, of Boston, in the county of Suffolk and State of Massachusetts.
'This Ainvention relates to new and useful improvements in furnaces for heating buildings by hot air 5 and consists in the construction and arrangement of parts hereinafter described.
In the accompanying drawing, Figure l represents a vertical section of the improved furnace taken on the line av a: of Fig. 2. Fig. 2 is a horizontal section of Fig. l taken on the line y y.
Similar letters of reference indicate corresponding parts. v
A representsthe fire-box. B is the surrounding casing. O are the air-tubes which pass through the casing at the bottom', as seen at D, and up through the cap of the casing, as seen at E, more or less in number. These tubes are surrounded with the products of combustion in the combustionchamber F above the re-box. By this'arrangement of the air-tubes the fuel is greatly economized. Gr is a horizontal partition attached to the casing B, dividing the chamber outside the casing into two compartments, the upper being the hot-air chamber, and the lower the cold-air chamber. They are marked, respectively, H and I. J represents one or more dampers or valves in the partition G, which are adjusted so that more or less cold air may be allowed to escape into the hot-air chamber and mingle With the hot air for regulating its temperature. K represents the walls of the furnace. L are the passages for the distribution of the hot air to the different apartments of the dwelling. M is the escape-pipe for the smoke and unconsumed gases. N is the doorway for the introduction of the fuel. O is the grate, and P is the ash-pit. R is the pipe by which fresh air is introduced into the cold-air chamber I, and Q is a damper by which the quantity thereof may be regulated.
Having thus described my invention, I claim as new, and desire to secure by Letters Patent- 1. The hot-air chamber H and cold-air chamber I, separated bya partition, Gr, having dampers J, when applied to a hot-air furnace, as and for the purpose set forth.
2.*The combination with subject-matter of first claim, of pipes C passing through the combustion-chamber F, as and for the purpose described.
