GRATE.

SPECIFICATION forming part 'of Letters Patent No. 718,536, dated January 13, 1903.

Application filed July 1, 1902. Serial No. 113,936. (No model.)

To aZZ whom it may concern:

Be it known that I, ISAAC D. SMEAD, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Grates, of which the following is a specification.

My present invention relates to grates for open fires; and the invention consists in a novel construction of the grate, as hereinafter more fully described.

In the accompanying drawings, Figure 1 is a front elevation of the grate, and Fig. 2 is a perspective view looking from the rear or opposite side.

In the use of open coal fires it is found that the air enters and the coal burns most at the center or middle portion of the grate, while at or near the ends of the grate it burns much less, the fire being practically dead at the ends while burning well at the center.

The object of my present invention isto remedy this difficulty, and this I accomplish by constructing the grate as shown in the accompanying drawings, in which A represents the grate as a whole. It is constructed with a series of vertical bars a, which also extend horizontally across the bottom to hold the coal, these bars extending from each end toward the center, as shown. At the center instead of the usual bars I interpose a portion in the form of solid plate C without any openings for the entrance of the air, this solid portion extending from the top downward and across the bottom, as clearly shown in Fig. 2. When thus constructed, it will be seen that the air will enter only at the opposite sides of the solid portion C, and thereby the fire is caused to burn at both ends of the grate as well as at the center, thus giving much better results. At the top I form a horizontal shaft B, which not only strengthens the grate, but serves as a foot-rest for warming the feet and on which articles can be set when it is desired to heat them for any purpose. At the center this shelf B is supported by a bracket (1 on the front of the central plate C, as shown in Fig. 1.

The grate shown in the drawings is designed for use within what is known as Smeads heating and ventilating open stove, used for heating and ventilating schoolrooms and similar bui1dings,and which is therefore made of a much larger size than the ordinary open or so-called Franklin stove and requires a much longer and larger grate, and to prevent the bars from being warped or bent by the heat they are connected to each other by a solid portion e in the vertical part of the grate, and, if desired, they may be so connected in the horizontal part also. It is obvious that this improvement is equally applicable to the smaller-sized grates set in the fireplaces used for heating a single room or Wherever an open fire is used, it only being necessary to proportion the solid part C to the size of the grate, whatever that may be. It is also obvious that the bars at the front may be arranged horizontallyon each side of the solid or closed portion C, as is sometimes done, instead of vertically, as shown, the operation and result being the same; but I prefer to make them vertical, as represented in the drawings.

The grate can be cast integral, or, if desired, the central part C may be made separately and then be fastened in place.

Having thus described my invention, what I claim is A grate for open fires, having its central portion made solid or imperforate with bars at opposite sides thereof, said solid portion and bars extending downward and backward to form both a front and bottom for the grate, substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

I ISAAC D. SMEAD.
