Letters Patent No. 94,625, dated September 7, 1869.
COAL-STOVE.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern:
Be it known that I, HORATIO D. MCGEORGE, of Rochester, in the county of Monroe, and State of New York, have invented certain new and useful Improvements in Stoves and Furnaces; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing, making part of this specification, in which Figure 1 is a vertical sectional view of my invention as applied to an ordinary base-burning heating-stove.
Figure 2 is a section of the hot-air core-chamber 0, taken in the plane of the red line at, and showing a plan or top view of the compound annular grate G.
Similar letters indicate corresponding parts.
The black arrows indicate cold-air currents and the red ones hot-air.
The main object of this invention isto utilize the core of heat existing in the centre of all fire-pots or furnaces; and
Its nature consists in placing an air-heating chamber or tube in the centre of the fire-pot, which receives cold air at the bottom, and discharges it, after being heated at the top, into the room.
It also consists in the construction of a compound annular rotary grate.
To enable others to make and use my invention, I will describe its construction and operation.
At the base of the fire-pot of ordinary base-burners, or other heating-stoves or furnaces, I place an annular open grate, G, composed of three parts, a, b, and 0, one being placed above the other.
The lower section a rests upon two or more lugs, g, fig 2, and is provided with several radial plates (1, connecting with the outer ring or circle.
Section I) is similarly constructed, and has several vertical points It, at or near'the periphery, that act as agitators when the grate is being shaken.
The upper section 0 has several radial arms, which may be strengthened by ribs '1'.
Section I) overlaps the lower one at the edge, and has a loop, '5, in front, to receive the shaker-bar.
The semicircular damper-plate P is pivoted to the flue at n by the crank-bar 0, fig. 2; and the handlever H is pivoted to the flue-plate at f by an eyebolt, so as to slide through it, and its inner end is connected to the crank, whereby the damper is operated.
The hot-air core-chamber C may be made of any desired form or size, but I prefer that shown.
It should be provided with suitable ribs or cairngations k, running vertically.
It is locked to the upper section 0 of the grate, so as to turn with it.
The hot-air exit-pipe J opens through the top of the stove, whence-it may be conducted to any other room.
That section of the hot-air core-chamberO shown at R, fig. 1, which is most liable to burn out or melt, should be encased with plates of fire-brick, soapstone, plumbago, or an equivalent material.
When the damper]? is set, as shown in fig. 1, the air would be'taken down through the core-chamber to supply the combustion, being heated, of course, before passing through the grate.
This would only be practised when but very little heat was required; but by turning the damper from over the opening of the flue F, the cold air is taken into the bottom, heated, and driven out through the top of chamber 0. 1
In this case, the atmospheric air must be supplied to the fire through the ordinary damper under the grate.
The whole grate and flue may be shaken by removing the detachable cap j, which is used to lock the end of the flue to the outer case of the stove.
\Vhen the fire is to be dumped, the grate-bars should i be set as shown by the full lines in fig. 2; but when fine'coal is to be used, they should be set as indicated by the dotted lines.
It will be seen that the size of the interstices in this grate may be increased or diminished, as desired.
The core-chamber C may be made in one or more sections, if desired.
What I claim as my invention, and desire to secure by Letters Pat ent, is'
1. In combination with the hot-air chamber 0 and flue F, the damper 1?, arranged and operating substantially as and for the purposes shown and described.
2. The compound annular rotary grate G, constructed and operating substantially in the manner and for the purposes shown'and described.
