lMPROVEMENT IN HEATERS.

Specification forming partof Letters Patent No. 40,366. dated October 20, 1863.

To all whom it may concern.-

Be it known that I, EDWIN SPRAGUE, of Allegheny City, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Heaters for Churches, &c.; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accom panying drawings, and to the letters of referonce marked thereon.

The nature of my invention consists in furnishing a stove with an inner and. outer airchamber, connected with a receiving-chamber, the whole being constructed arranged, and operating in the manner hereinafter described.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In the accompanying drawings, Figure 1 is a side view of the heating apparatus. Fig. 2 is a sectional view of the same.

a represents the outside casing, which surrounds the body 0 of the stove.

1) represents the doors of the casing to.

0 represents a pipe, which is placed in the center of the stove. This pipe forms the inner air-chamber, and is connected with the outer airchamber, w, by means of a pipe, y.

f represents the bottom, and 9 represents the top, of the stove.

h represents the receiving-chamber, which is connected with the smoke-pipe k by a branch pipe, j, which is furnished with a damper, r.

t represents a water-vessehjwhich is placed on the top 9 and around the pipe 6.

q represents air-passages which lead into the air-chamber m.

0 represents a register, which is used for regulating the admission of cold air into the pipe e.

19 represents the grate of the stove.

8 represents thc-ash-pans.

1 represents the feet of the stove.

61 represents the fire-door.

n represents poker-holes.

t represents a door leading into the receiving-chamber h.

z represents a register placed on the upper end of the receiving-chamber h.

It will be observed that two or more pipes,

set forth.

similar to the pipe y, may be used for connectin g the chamber or with the pipe e, and it will also be observed that the ash-pans s and grate p are made so as to surround the pipe 0.

The operation of my improvement is as follows, having all things constructed and arranged as herein described and represented: I place the heating apparatus in the basement of the church, and connect the smokepipe to the ordinary flue of the building, and I also connect the receiving-chamber h to a register placed in the floor of the room above the basement, by means of a pipe, or by makin g the receiving-chamber hof sufficient height to reach up so that it maybe connected to the register in the floor above. I then make a fire in the stove so that it will surround the pipe 6. I then open the register 0 at the bottom of pipe 6, so that it will admit the desired quantity of air into the pipe 6. The air thus admitted becomes heated as it passes up through the. pipe 6 into the receiving-chamber h. The air which passes into the chamber as through the openings q is heated by the body 0 of the stove. This heated air passes up and through pipe y into pipe 6, and from it into the receiving-chamber h, from which the heated air is admitted into the upper room or body of the church by means of a suitable register.

Water is placed in the vessel t for the purpose of imparting a moisture to the heated atmosphere in the room.

The admission of the heated air into th room is regulated by the use of the register and the damper 1". When the room is too much heated, the damperr is turned so as to allow the heated air to escape through the branch j into the smoke-pipe 70.

Having thus described the nature, construction, and operation of my improvement, What I claim as of my invention, is-- The arrangement of the pipe 8, register 0, chamber w, pipe y, receiving chamber h, branch j, damper r, and vessel t, the Whole being constructed, arranged, and operating substantially as herein described, and for the purpose EDWIN SPRAGUE.
