T0 on whom it may concern:

Be it known that 1, CHARLES L. BEERS, a citizen of the United States, and a resident of Scranton, in the county of Lackawanna, in the State of Pennsylvania, have in vented new and useful Improvements in Fire-Box-Lining Supports, of which the following,taken in con-- nection with the accompanying drawings, is a full, clear, and exact description.

Thisinvention relates to the fire-boxes of stoves and ranges, and has special reference to the devices employed for supporting the fire-brick linings in said fire-boxes The object of the invention is to provide a supporting device which shall be simple and inexpensive in construction, adapted to be readily applied to any stove or range, and adjustable to varying depths of fire-boxes; and to that end the invention consists in the comwith the movable grate and fire-box lining, of plates disposed in juxtaposition to and parallel with the walls of the fire-box and provided with ledges for supporting the firebrick lining, said ledges being situated above and extending over part of said movable grate, and means for adjusting said plates to and from the grate.

In the accompanying drawings, Figure l is a top plan view of a fire-box provided with my improved means for supporting the firebrick lining. Fig. 2 is a vertical transverse section of the same. Fig. 3 is a detached perspective view of my preferred construction of the fire-brick-lining supporter. Fig. 4 is a plan View of the blank from which said supporteris formed. Fig. 5 is a face view of a modification of my invention, and Fig. Fig. 6 is an end view of the same.

Similar letters of reference indicate corresponding parts.

0 represents the fire box of a stove or range, and D is the grate, which may be of any suitable shape. The inner walls of the fire-box above the grate are protected by lirebrick linings, as indicated by dotted lines 1 l in Fig. 2 of the drawings.

In some fire-boxes the front is protected by a water-chamber covering the front wall of the fire-box and dispensing with the fire-brick lin- 5o ing thereat.. In cases where the fire-box is deprived of such water-chamber the fire-brick linings Z Z are applied to the front as well as to the back of the fire-box, as shown in Fig. 2 of the drawings. These linings have heretofore been supported upon a horizontal frame which was supported upon lugs on the front and rear walls of the fire-box and upon the tops of the grate-hanger boxes at a. In the use of such supporting-frame it has been found that it is liable to sag onto the grate and prevent the same from turning. To obviate this defect, I employ is provided at its base with a ledge c, constituting the seat of the fire-brick lining. This plate, with its ledge, I preferably form of a wrought-iron blank B, (shown in Fig. 4 of the drawings,) which blank I bend along the dotted line 0 at the requisite angle to form the ledge 0. (Shown in Fig. 3 of the drawings.)

To guard more efiectually against the sagging of the ledge c, I form the central portion of the plate 12 with a vertical extension, as shown at b, and perforate said extension, as shown at e, for the reception of bolts or other suitable devices for fastening said plate to the wall of the fire-box. Said perforations may be made to secure the plate I) in proper position to carry the ledge o in its requisite proximity'to the subjacent grate D, as shown in Fig. 2 of the drawings. Consequently the said plate, with its ledge, is adapted to be applied to fire-boxes of varying depths.

The aforesaid construction dispenses with the usual false back of the fire-box. however, limit myself to the construction shown in Fig. 3 of the drawings,inasinuch as myimproved fire-brick supporter may be constructed as shown in Figs. 5 and 6 of the drawings, in which the ledge c is formed separate from the plate I) and is secured thereto by angle-irons f f, riveted to said parts. this case the plate I) is reinforced by a hanger or vertically-elongated plate h, formed at its base with a horizontal ofiset 77., upon which the center of the ledge c rests. This hanger and its offset are fastened, respectively, to the plate Z) and to the ledge c by means of rivets 'i z'.

The hanger is perforated, as shown at t t,
