GRATE.

SPECIFICATION forming part of Letters Patent No. 485,450, dated November 1, 1892. Application filed November 16, 1891. Serial No. t172,011. (No model.)

To a/ZZ whom t may concern,.-

Be it known that we, FREDERICK CAREL.

and WAYLAND F. DAVIDSON, of Charleston, Kanawha county, lVest Virginia, have invented a new and useful Improvement in Grates; and we do hereby declare the followlng to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification.

This invention is an improvement in grates; and it consists in certain features of constructlon and novel combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure l is a face View of our grate as in use. Fig. 2 isa sectional view on line 2 2 of Fig. l. Fig. 3 is a detail view of the partition. Fig. 4 is adetail view illustrating the hase and one of the edge plates. Fig. 5 shows the invention applied to four rooms, and Fig. 6 is a detail view of parts shown in Fig. 5.

The grate A has one side Bv'lattened and its opposite side C rounded or projected and is journaled at D between said sides B and C, so that the grate may be turned to present either its flat or rounded side and so form either a recessed or a projecting grate. This will be readily understood from Fig. 2, in which the grate is shown in connection with two rooms, and is arranged to form a recessed grate in one of such rooms and a projecting grate in the other. Manifestly this construction of grate will be useful in heating a single room, or may, if desired, be employed in connection with two, three, or four rooms, and may be preferred because of its adaptation to enable the presentation of a projecting or flat recessed front, thus providing, practically, two kinds of grate in one.

Centrally at its lower end the grate is journaled on the base F, being provided with a socket e, which fits andturns on a pin E on the said base F. This base is shown as a bar resting at its lower edge fiat upon the floor or hearth of the fireplace. The base-bar, it will be seen, serves to prevent the passage of light and sound along the hearth between two or more adjoining rooms and may be provided at its ends with suitable feet, as shown.

Plates G t at their outer edges closely 'to the walls of the fireplace, and lap-plates H are arranged and adapted to lap against the sides of the plates G and to close the Space between the inner edges of the said plates and thegrate. In the construction shown in Fig. 2 the lap-plates H are in the nature of fianges projected from the grate, the opposite lap-plates being arranged to lap 6o when the grate is in use against the opposite sides of the opposite plates G-that is to say, one of the plates H is lapped against the front side of one plate G and the other plate H is lapped against rear side of the other plate H. This arrangement of the plates G and H permits the grate to be given a halfturn to adjust it to present one or the opposite side, as may be desired, and in bot-h positions the plates G and H will exclude the 7o passage of light and sound alongside the grate. In the said construction the plates H are pre ferably cast integral with two of the gratebars, and the plates G are fitted and held at their lower edges in grooves f, formed in the base-bars, such grooves being preferably undercut and the lower edges of the plates being formed to fit in such grooves, as will be understood from the drawings. These plates G extend up to and are conformed to the top 8o of the fireplace, which, manifestly, may be square, as shown, or rounded, as may be desired.

The partition I, which may be employed to divide the grate into two compartments, is made hollow and open at its upper and lower ends, so that air may circulatethrough it, and thus tend to prevent its undue heating and consequent cracking and warping. At its edges this partition fits in guides in the grate, 9o

and it extends up above the top of the grate and projects up .at i to the top of the fireplace, the cover-sections J being tted over the grate-compartments and up against the partition. Above the top of the grate the partition I is extended edgewise laterally beyond the side of the grate at I and forms, practically, a continuation of the plates H, such eX- tensions I being in alignment with the said plates H and lapping, like such plates, alongroo side the plates G, as shown.

While the construction of the plates for preventing the passage of sound and light between the adjacent rooms may preferably be as described for two rooms, it is obvious that it may be modified when the grate is used in connection with four rooms, as shown in Fig. 5. In such construction, which, manifestly, may be also used whenthe grate is used in connection with two rooms, We provide plates G, each being fitted at its ends in grooves in the base plates or bars, and the lapplates, instead of being projected from the grate, as shown in Fig. l, are held -to the plates G, so that they can be slid out and in to 'fit between or rest clear of the grate-bars, as will be readily understood from Fig. 5. In this construction, like that shown in Fig. l, the plates H serve to close the space between the inner edges of the plates G and the grate and are lapped alongside the said plates, as shown. By preference the plates H in this construction are secured to the plate G by means of bolts or rivets passed through the plates H, and thence through slots in the plates G. Now it will be seen that the construction of the base prevents the passage of light and sound below the grate, the plates G and H prevent such passage alongside the grate, and the upward extension of the partition prevents the passage of light or sound above the grate, thus making the adjoining rooms, whether they be two or four, entirely private, and at the same time enabling the use of one grate to heat two or more rooms.

In the four-room construction sub-partitions are usually employed to subdivide the compartmentsformedbythepartition I. Such sub-partitions will be extended upward and forward at their outer edges above the grate, similarly to the partition I, as before described.

In case the plates G should become unsteady or wabble any they may be cast with small perforated lugs or ears forthe passage of nails, by which they maybe fastened in the fireplace.

We claiml. The combination, substantially as herein described, of the base having grooves in its upper side,the grate journaled centrally upon the said base, the plates G, held at their lower edges in said grooves, and the plates H, arranged to close the spaces between the plates G and the grate, all substantially as and for the purpose set forth.

2. The combination, substantially as herein described and shown, of the grate, the base, the plates G, the lap-plates H, arranged to close the spaces between the plates G and the grate, and the partition fitted in and extended above the grate and having its edges above the grate arranged to lap against the plates G, substantially as and for the purpose set forth.

3. The improvement in grates, substantially as herein described and shown, comprising the base having grooves in its upper side, the plates G, held at their lower edges in said grooves, the grate journaled on the said base and provided with ange-like plates H, arranged to lap against the plates G, and the partition fitted in the grate and projected above the same, the edges of the said partition above the grate being arranged in line with the flange-plates H and to lap against the plates G, all substantially as and for the purpose set forth.
