CHARLES H. GIBBS, OF BUFFALO, NEW YORK.'

HEATING-STOVE GRATE.

SPECIFICATION forming part of Letters Patent No. 227,242, dated May 4, 1880.

Application filed February 19, 1880.

To all whom it may concern:

' Be it known that I, CHARLES H. GIBBs, a citizen of the United States, residing at But'- falo, Erie county, State of New York, have invented new and useful Improvements in Heating-Stove Grates, ot which thel following is specification.

This invention relates to certain improvements in that class of stove-grates which are constructed with a cone-shaped dumping-section arranged within a surrounding annulus or ring.

My invention consists of an oscillating central conical grate-section formed with a laterally projecting operating handle and lugs which set in recesses in a surrounding' conical annulus or outer section, said outer section rest-ing at opposite side edges upon bifurcated brackets formed on the upper side of a permanently-fixed cross-bar, all of which will be more fully hereinafter described in detail.

In the accompanying` drawings, Figure l represents a perspective view of a grate constructed according to myinvention. Fig. 2 is a longitudinal vertical central section through the grate and the supporting cross-bar. Fig. 3 represents a perspective view of a portion ot' the lower section ofthe grate, showing one of the recesses for the lugs on the upper section; and Fig. 4L, a perspective view of a portion of the upper section, showing one ot' the lugs for supporting the saine.

Referring to the drawings, it will be seen that my improved grate is composed of two conical sections, the upper section, M' of which is detachably connected with the lower section, m, and arranged within the same so that it can be readily tilted for the purpose 0f dumping the grate. The apex of the section M' extends upward within the lower portion of the fire-pot, and the lower edge of said section is provided with two opposite radiallyprojecting lugs, m', rounded on their lunder sides, which rest in corresponding receivers or seats in the lower and outer section, m, and said grate-section M' is also provided with a shaking-handle, N, which curves outward under the outer section, m, and is provided with a suitable socket for a shaking-wrench. The outer section, m, ofthe grate rests directly upon the tips et' the upwardly-projecting prongs of bifurcated brackets O, secured near the opposite ends ot' a permanent cross-bar, P, the ends of which are beveled, as at p, and are adapted to be secured to a correspondinglybeveled seat in an ordinary stove. 'Io points diametrically opposite each other a cross-bar, R, is securedto the under side of the outer section, m, and this cross-bar has atits center a downwardly-projecting journal, r, which tits into abearing formed for it at the center of permanent cross bar P. The permanent cross-bar I3 forms a firm support for the entire grate, and the bit'urcated brackets, while maintaining the grate in a horizontal plane during its oscillation, prevent the same from canting to one side and dumping the fuel and fire into the ash-box. 'Ihe conical form ot the grate M' prevents clinker and ashes from accumulating on the grate and in the iire-pot, as they will be entirely removed from the grate and slide down into the ash-pit by shaking or oscillating the grate. This constitutes an irnportant feature ot' my invention, sincel it obviates the necessity of removing the clinkers byopening three or more doors and picking them out with a hook, which, as is usual with other forms of grates, is an inconvenient operation, and also gets the ashes over the stove and upon the oor of the room in which the stove is located.

By pressing down the handle N the center section, M', of the grate can be readily tilted on its lugs m' for the purpose of dumping the dead cinders and ashes when it is desired to clean out the fire-pot.

What I claim is-I l. The stove-grate herein described, consisting of an oscillating upper conical section, M', and lower section, m, the conical upper section, M', being provided with the handleN and with the lugs m', pivoted in bearings diametrically opposite each other in the lower section, m, substantially as described.

2. The combination of the permanent supporting cross-bar, P, provided with the vertical bifurcated brackets O, the oscillating In testimony whereof I have hereunto set 1c cross-bar R, pivoted at the center of said permy hand and seal in the presence of two submanent bar, the lower conical grate-section, scribing witnesses.

m, rigidly connected to the opposite ends of 5 said oscillating cross -bar and bearing` upon cuARLEs H. GIBBs. [L s] saidbifurcated brackets, and the upper conical grate section, M', pivoted Within said Witnesses: lower conical gratesection, substantially as W. E. HOLGOMB, described. JAMES D. WOOD.
