DAVID STUART AND LEWIS BRID GE, OF PHILADELPHIA, PENN- SYLVANIA.

Letters Patent No. 90,910, dated June 1, 1869.

IMPROVEMENT m FIRE-PLACE s'rovns.

The Schedule referred to in these Letters Patent and making part Of the ame.

To all whom it may concern:

Be it known that we, DAVID Scream and Laws BRIDGE, both of Philadelphia, Pennsylvania, have invented certain Improvements in Base-Burning Fire- Place Stoves; and we do hereby declare the following to be a full, clear, and exact .description of the same.

.Our invention relates, for the most part, to certain improvements in base-burning fire-place stoves, for

which Letters Patent were granted to us, J one 23,

' enters the room in which the stove is situated, as well as that-which is conducted to the rooms above, all substantially as described hereafter.

In order to enable others skilled in the art to make and use our invention, we will now proceed to describe its construction and operation, reference being had to the accompanying drawing, which forms a part of this specification, and in which- Figure 1 is a perspective view of our improved fireplace stove;

Figure 2, a transverse section of the same; 7

Figure 3, a view of the top of the stove, with the. screen removed;

Figure 4, a perspective view of part of the hearthplate; and

Figure 5, a perspective view of part of the fender.

Similar letters refer to similar parts throughout th several views.

Ourpresent invention relates, for the most part, to

' improvements on the base-bur'ning fire-place stove for which Letters Patent were granted to us on the 3d day of May, 1867.

In the latter stove, the bottom -plate A was arranged to bear directly on the floor, to which undue heat was consequently imparted and this is common to all fire-place stoves.

In order to obviate this evil, and at the same time avail ourselves of the heat of the bottom-plate, the latter iselevated, in our present improvement, a short distance above the floor x, by suitable projections a, thus forming an air-chamber, A, between vthe said bottom-plate and the floor, communicating with the hot-air chambers at the back of the stove, which are so fully described in our former patent, that a descripv tion of them here will be unnecessary.

Thus, the heat of the bottom-plate, instead of being imparted-to the floor, is added to the heat distributed from the hot-air chambers, either into the room or into passages communicating with upper room's.

The bottom-plate A is continued outward in front, so as to form a hearth-plate, B, the flange b, on the outer edge of which, rests on the floor, so that the space beneath the hearth-plate and the floor forms a continuation of the above-mentioned air-chamber, to which air is admitted through perforations in the said fiangeb.

The hearth-plate B is, in the present instance, de-

tachable, the rear edge resting on aflange of the bottom-plate, in which are holes for receiving pins (2, on I the hearth-plate. (See fig. 4.) v

The detachability of the said hearth-plate renders it more convenient for cleaning-purposes,

On the hearth-plate, and supported by pins 0 e, is a rail, or fender E, afiording a rest for the feet.

A central portion, E, of this fender, with its pin 0, is made detachable, the lower end. of its 'pin fitting loosely into a hole in the hearth-plate, (fig. 5,) and its opposite ends resting on the other parts of the fender, which are secured permanently to the hearth-plate.

On removing this central section E of the fender, the ash-drawer F can be removed and replaced.

Instead of the section E of the fender being entirely detachable, it may be pivoted at one end to the permanent portion of the rail, so as to be turned outward when the ash-drawer'has to be removed. 3

The stove is furnished with a feeder, or coalereservoir, similar to that described in our former patent,

and shown at fig. 2, the fuel being introduced at the top.

Although we have illustrated and described the screen, we make no claim to.it here, as it forms the subject of another-application for Letters Patent.

The feeder is suspended within a casing, Q, which may be found in other base-burning stoves, the space W, between this casing and the outer casing V of the stove, being a hot-air chamber, within which, near the top of the stove, we place auannular vessel, q, for containing water, this being so situated that the vapor for purifying the heated air will unite both with that which passes into the room and that which is con;- veyed to upper rooms-an arrangement which may be used to advantage in other base-burning stoves. We claim as our invention, and desire to secure by Letters Patent l. A fire-place stove, having at the base aflange,

or hearth-plate, B, arranged substantially as dechamber of a base-burning stove, which contains the feeder, so as to communicate both with the lower and with the upper chamber, for the purpose specified.

In testimony whereof, We have signed our names to i this specification, in the presence of two subscrihing witnesses.

JOHN WHITE, 0. Howson.
