IMPROVEMENT IN FIRE-PLACE GRATES.

Specification forming part of Letters Patent No. 142,5 1 1, dated September 2, 1873; application filed May 27, 1873.

To all whom it may concern:

Be it known that I, JOHN S. RUNYAN, of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Gratesfor Fire-Places,

of which the following is a specification:

is a plan view, showing the grate, the rake,

the hearth, and vertical fiues in the rear wall of the fire-place for the passage of air. Fig. 4c is a plan view of the frame upon which the sliding rake rests, and Fig. 5 is a plan view of the rake.

Corresponding letters refer to corresponding parts in the several figures.

This invention relates to grates to be used in fire-places. My invention consists in combining with the horizontal and vertical portions of the, grate, basket, brackets, and a hearth supported thereon; and, further, in constructing the back wall of the fire-place with a transverse recess formed therein at the end of the grate, connected with which there are vertical recesses extending a short passage of the air up through the fuel, and

for the passage of the ashes to the ash-pit below; it is also provided with apertures through its front bar for the passage of pins or bolts for the retention of the front portion of the grate and the hearth. Underneath the grate A there is placed a frame, B, which rests upon supports formed in the walls of the fire-place, it being provided with a depression in its front bar, and with cross-bars fitted for the or more longitudinal bars of metal, and two or more cross-bars, the longitudinal bars hav ing upon them vertically projecting teeth, which are of sufficient length to enter the spaces between the bars of the grate A, in order that as the rake is drawn outward and pushed inward the fuel will be agitated, and the ashes and clinkers will be caused to fall down into the ash-pit. For convenience in moving, this rake has attached to it a handle, 0, which projects outward, and may be provided with a rod of iron for moving it, if desired. In front of and rising above the grate A and rake 0 there is placed avertical portion, D, of the grate, which consists of horizontal and vertical bars, and is provided with hooks or other suitable devices for securing it to the walls of the fire-place, and with projecting pins or bolts for entering the apertures formed in the horizontal portion A of the grate.

The construction and arrangement of the grate proper are shown in Figs. 1 and 2, where it will be seen that there are brackets E E attached to the outer surface of the vertical portion D of the grate. These brackets serve to support the hearth F, which is attached to their lower ends, it being made in the form of a segment of a circle, or in any other suitable form.

To produce as perfect and uniform combustion of the fuel in the grate as possible, and at the same time protect the back part of the fire-place from the heat of the coalbanked against it, I construct the back wall of the fire-place with a transverse recess, Gr, formed therein at the end of the horizontal part of the grate, and from this recess I extend other vertical recesses or fiues, H H, upward to about the height of the front part of the grate, where these fiues are terminated, so that the ascending current of air shall be passed through the coal banked against the back wall. 7

This last-named arrangement of the passage for air will be found to be of great importance in promoting the combustion of the fuel in that part of the fire-place, and also in protect ing the same from the action of the intense heat when the material employed in its con struction is cast-iron.

Having thus described my invention, what of the grate, the brackets E E, and the hearth I claim, and desire to secure by Letters Pat- F, substantially as and for the purpose set cut is forth.
