FURNACE-GRATE.

SPECIFICATION forming part of Letters Patent No. 240,949, dated May 3, 1881.

Application filed January 7, 1881.

To alt whom it may concern:

Be it known that I, OHARLEs Ti BEERs, of Norwalk, in the county of Fairfield and Sta-te of Connecticut, have invented a new Improvement in Furnace-Crates; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, which said drawings constitute part of this specification, and represent, in

Figure l, a top View; Fig. 2, a sectional front view; Fig. 3, a sectional side view from one side; Fig. 4, a sectional side "iew from the opposite side.

This invention relates to an improvement in grates, especially adapted to furnaces for heating purposes, alsoapplicable to other purposes, the object being to apply to the grate either a tipping or a shaking movement, or both; and the invention consists in the construction as hereinafter described, and particularly recited in the claims.

A represents the grate, which is circular in form and provided with the usual openings for draft and for the passage of ashes.

Below the grate and across the ash-pit B is a shaft, C. The shaft has a bearing at each side, upon which it may be oscillated. This shaft extends diametrically across the grateopening, and the grate is provided with a central stud, D, which lits into a corresponding seat in the shaft C, so that the grate may be rotated in a horizontal plane, with said stud D as its center of rotation. The shaft C, being permitted to rotate, tips the grate from its horizontal plane, as for the' purpose of dumping,

'&c., and as seen in broken lines, Fig. 4.

For the purpose of tipping the grate, an arm, E, extends down from the, shaft C below the pivot, and from thi* arm a connecting-rod, F, is jointed to a rocki g lever, G. The pivot g of the lever Gr extends through the case to the outside, and is fitted for the application of a crank or lever, as in the usual manner,for shaking or dumping the grate, so that a crank or lever applied thereto will turn the lever G, as seen in broken lines, Fig. 4, to tip the grate.

To shake the grate a rocking lever, H, is ar- (Model.)

ranged within the ash-pit, its pivot h extending outside for the application of the crank or lever thereto, as before described, so as to vibrate the said lever, and from the opposite end of the lever H a connecting-rod, I, extends to and in connection with the grate, here represented as by a trunnion, e', on the grate, resting in a loop or eye, L, on the end of the connecting-rod I, and so that by turning` the lever H up and down, as indicated in broken lines, Fig. 3, a rotating or oscilla-tin g movement will be imparted to the grate and in its own plane, which will disturb the fire upon it so as to cause the ashes to fall through the grate.

The grate can be oscillated after it is tipped, if it is found desirable so to do, in order to clear the clin kers and ashes therefrom.

I am aware that iire-grates have been arranged so as to be rotated and oscillated in their horizontal plane, and also so as to be tipped for the purpose of dumping.

I claiml. A furnace-grate arranged upon a horizontal shaft beneath it, a rigid arm, E, extending downward from said shaft, and a rocking lever, G, connected by a rod, F, to the said arm E, substantially as and for the purpose described.

2. A furnace-grate pivoted to a horizontal shaft beneath it, and adapted to be turned on said pivotin a horizontal plane, combined with a rocking lever, H, and a rod, I, connecting said lever directly to the grate, whereby a rotary motion in a horizontal plane may be imparted to said grate, substantially as described.

3. A furnace-grate arrangednpon a horizontal shaft beneath it, an arm, E, extending downward from said shaft, a rocking lever, Cr, connected by a rod, F, to said arm E, whereby the grate is tipped, combined with a rocking lever, H, and a rod, I, connecting said lever H directly to the grate, whereby the grate may be rotated upon its pivot, all substantially as described.
