Letters Patent N 97,970, dated December 14, 1869; antcdatezl November 23,1869.

BASE-BURNING- IIRE-PLACE' HEATER.

' The Schedule referred to in these Letters Patent and makingpart of the same.

t I, SAMUEL B. SEx'roN, of the city of Baltimore, in

the State of Maryland, have invented certain new and useful Improvements in Base-Burning Fire-Place Stoves,.so1ne of which improvements are applicable to heating-apparatus of other kinds.

My said invention is described as follows:

Nature muLObjcctsof the I attention.

This invention relates chiefly to what are known as 'magazine fire-place heaters, being a class of heatingstoves which is adapted to be set partially within the chimney or fire-place, to heat air fog the warming of apartments above that inwhich the stove is placed, and to receive their fuel through a magazine or chamber, at the base of which the combustion takes place; Someof my improvements are-however, applicable to stoves and fire-places ofother kinds, as will be here'- inafter explained.

My invention consists, first, in constructing the stove .with a magazine whose walls are exposeddirectly to the atmosphere, a feed-door or conductor for supplying the magazine with fuel, and a separate valve, by which gases are prevented from passing upward through the magazine while the stove is in full operation, but may be carried off into the ,dischargeflue before opening the feed-door for the introduction of fuel; second,

in combiniug,with the exposed magazine, reflexed pipes or columns for conducting gases to the lower part of the stove from the combustion-chamberbeneath or around the lower part of' the magazine; tbird, in a peculiar combination and arrangement of flue-pipes, as hereinafterset forth; fourth, in a shield 'or screen, adapted, as hereafter describechto besecured in front tion of the external walls of the stove.

Figure 4 is a vertical section, in the plane indicated -'hy the line z z, fig ..2.

Figure orepresents a vertical section at g/y, fig. 1, the plane of sectionbeing at right angles to that shown Similar letters of reference'indicate corresponding parts in the severalxviews.

The lower part A of the magazine extends down- -or ventilating the apartment.

ward within the combustion-chamber B, in the customary manner.

G is the grate; D,- the ash-pit; and

D, an ash-drawer or pan. s

The walls of the combustion-chamber B are prov vided with the customary illumination vindows b b.

E E are flue-columns or pipes rising fromthe firea chamber B, bent over at top, and descending to the flue-chamber F, at the base.

G G are flues or pipes rising from the lower chamber F to the upper flue-chamber H, which communicates with the discharge-flue I, as shown in fig. 5.

J is a door or cover closing the opening through which fuel is supplied to the magazine A. The said opening may be made directly in the external wall of the magazine, or a conducting-tube or funnel, I, may be employed, as shown in fig. 5. i In the top of the magazine is formed a valve, K, which may he opened to afford more free and direct draught in kindling the fire, and must be opened to discharge gases from-the magazine before opening the door J for the introduction of fuel.

The pipes E E are provided with the customary dampers e 0.

Doors ff afford access to theflue-chamber F, for the purpose of cleaning the same, or checking the fire,

L L areyariousparts of the external casing, within which, around and above the stove, is thechamber in which air is heated to be carried up through the chimney M to apartment-s above.

The front part of the stove is surmounted by a crown-plate, N, which, partially covering the space between the stove and the casing L, makes a neat and ornamental. finish, and, being perforated, allows the escape of heated air into the room.

0 represents an ornamental shield or screen, which may be employed to cover the front of stoves of cheap and plain exterior, or to cover the fire-place in summer-time. y

The said shield or screen is perforated, as shown at o 0, to permit the passage of air into the room, and is preferably formed with one or more doors, to afford access to the stove without removing the screen.

It may be secured in position by means of projecting studs, fitting in holes-q q in the front of the stove, or

it may be made in two pieces; and hinged at the sides to either the stove, or the frame, or casing,the hinges being so constructed as to permit the screen to be liftedoffand removed at pleasure, or to slide back, into the rear or interior, if desired.

Betweeirthe walls of the combustion-chamber B and the cylindrical fire-pot B below it, I form a shoulder, 7), as shown in the drawings. This is of great advantage in various ways. The windows are thereby removed to a greater distance from the burning fuel, and the combustion is rendered more active and complete.

Operation.

To start the fire, or to discharge gases from magazinc, the valve K, at the top of magazine A, is opened.

W hen the fire is burning, and the magazine supplicd, the valve is closed. The products of combustion then pass from the chamber B, through the pipes E ll, to the base of the stove, and thence upward, through one or more pipes, G G, to the upper chamber H, which communicates with the discharge-flue I.

The checking of the draught may be effected by closing dampers c in the pipes E, or by opening the doors ff, to admit air to the lines at the base of the stove, which latter arrangement afi'ords effective ventilation.

A drawer may be employed, to receive the ashes and close the ash-pit in customary manner, or, if preferred, a common pan may be used, and the ash-pit closed by doors.
