IMPROVEMENT IN HOT-AIR FLUES FOR HEATlNG-STOVES.

Specification forming part of Letters Patent No. 128,297, dated June 25, 1872.

SPECIFICATION.

invented certain Improvements in Hot-Air Flues for Stoves, of which the following is a specification:

Nature and Objects of the Invention.

This invention relates to the hot-air flue O, with its wings b. Said wings are situated near its upper end, and serve to secure it in its position. The lower end of the flue rests on the fire-grate instead of passing clear through the shell of the stove, as is usual, thus taking the air through the grate Said flue also economizes fuel, as it fills up the fire-space more or less, and becoming red hot, as it will, substitutes in itself the place of the fuel which it displaces. The ring B, which is secured in the body of the stove, near the top, by the projections a, serves as a support for the flue. Suflicient space is left between the outer edge of the ring and the walls of the stove for the passage of the coal. When the flue is applied to a magazine-stove said flue is constructed of any material that will stand the heat. This flue can be applied to any of the upright stoves now in use without the necessity of any alteration in the stoves. A pipe can be attached to the upper end of the flue for the purpose of heating rooms above.

Description of the Accompanying Drawing.

Figure I is a view of the stove with part of its outer shell removed, and shows the position of the hot-air flue G and with its end E resting on the fire-grate. Fig. II shows the supporting-ring B; Fig. III, view of the flue, and showing the wings D.

General Description.

At A, Fig. I, is shown the body of a stove with part of its shell removed, showing the position of the hot-air flue O, as placed therein. The end E of said flue is open and rests on the upper surface of the fire-grate F, and takes the air from below the grate, instead of from the outside of the stove. The object of this is the flue can be applied to any upright stove now in use without any alterations in them. The ring B is secured inside the stove, near its top, and forms a support for the flue. The wings I) on the top end of the flue rest against the interior of the ring between the projections a. Sufficient space is left for the admission of the fuel to the lire when the stove 7 is filled from the top.

This is an economical attachment to a stove, as the amount of fuel which is displaced by the flue is compensated for by the heating of the flue itself. If upper rooms are required to be heated, a pipe can be attached to the upper end of the flue and carried through the floor.

What I claim as my invention, and desire to secure by Letters Patent, is-- l. The flue G, with its projecting wings I), substantially as and for the purpose as hereinbefore set forth.

2. The combination of the flue C with its wings I), the ring B with its projections a, and the stove A, substantially as and for the purpose as hereinbefore set forth.
