INIPROVEMENT IN HEATING-STOVES.

The Schedule referred to in these Letters Patent and making part of the 5 m- To all whom it may concern Be it known that I, THEODORE BROCKMANN, of Davenport, in the county of Scott, and State of Iowa, have invented certain new and useful Improvements in Heating-Stoves; and I do hereby declare that the following is a full, clear, and exact description thereof,

reference being bad to the accompanying drawings,

making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention, I will proceed to describe it.

My invention relates to aheating-stove, of novel construction; and consists in a peculiar arrangement of the parts, whereby the fire-back, or a part thereof, or the grate, or grate-frame, or all three, may be removed, without taking the stove down.

In the drawings Figure 1 is a horizontal cross-section, on the line y Figure 2 is a vertical section, on the line x a; of fig. 1;.

Figure 3 is a section through the fire-back, on the line z z of fig. 2;

Figure 4 is a front view of the lower portion of the Figure 5 is a front view of the upper section of the same; and

Figure 6 is a view of one-half, or section, of the grate-frame.

A represents the body of the stove, and

O, the grate, which is stationed in the lower front part of the same.

Immediately behind the grate, is the vertical fire back B, occupying the whole width of the stove, and reaching within four or five inches of the top.

The tire is built upon the grate G, and the smoke passes up over the top of the back, B, and (the valve 9 in pipe I being closed) thence passes down behind the back, B, through the vertical fines E, into the horizontal fines G, in the base of the stove, and from these around into the pipe F, and thence to the chimnev.

\Vhen a strong draught is required, the valve 9 is opened, and the smoke passes directly over the top of the fire-back, into the chimney, through pipe I, without its being required to pass through the great length of fines.

To provide for the easy removal of the fire-back, when burned out, I construct it in three sections, or pieces, a, b, and d, the lower part of the back being formed of the two pieces a, and I), fastened together, and the upper portion in one piece, (I.

The pieces or and b are each one-half the width of the stove, and are put together with a lap-joint, and secured by the screw-bolt 0, as clearly shown in figs. 1, 2, 3, and 4, the whole being held in position in the stove by the ribs 70 It, as seen in figs. 1 and 2.

The'upper portion (1 of this back is made in one piece,

the width of the stove, and is secured in position by the ribs k at one end, and at the other by a lug, j, as shown in figs. 1 and 2.

This plate (Z has an offsetting flange, or edge, which, when the plate is in position, projects down over the upper edges of plates a b, on the inside, and thus closes the jointvbetwecn them and plate a, and pre-. vents any ashes from working through into the chamber, or flue E, and also, in connection with thearnis h on theback of plate (1, serves to hold the plates a b rigid. I

When the upper portion at of the back is to be removed, it is lifted until the opening 0 in its side comes opposite the lug j, when the plate may be lifted out of place, and removed through the door of the stove.

When the lower plates are to be removed, the screwbolt 0 is withdrawn, by introducing the hand through the door, and the plate at is liftedfar enough to disengage the arms h from it, and then the plates a and b may be removed separately through the door.

The grate-frame D is made in two parts, as shown in fig. 1, (the joints being at 6,) and one of the pieces separate, in fig. 6, and the whole is supported by flanges cast upon the stove-body, and upon the fire-back, so that, after the grate is removed, the frame may be lifted out in separate pieces.

' A stove, thus constructed, possesses many advantages over the old forms, as the fire-back grate, grateframe, or all three, may be removed in a moment, and that without taking the stove down, as is usual.

By placing the valve 9 in the pipe, and extending the chamber E entirely across the stove, the line is less likely to become choked upwith soot or ashes, or the valve to be warped by the heat.

Having thus described my invention,

What I claim, is

l. The detachable back, consisting of the plates a, b, and (Z, constructed and arranged substantially as herein shown and described.

2. The grate-frame D, formed in two parts, as described, to permit of its ready removal, in themanner set forth.
