Letters Patent No. 92,906, dated m 20, 1869.

STOVE-GRATIS.

' The Schedule referred to lnthese Letters Patent and making part of the same.

To whom it may concern:

Be it known that I, CHARLES .TRUESDALE, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Shaking and'Dumping-Grate; and I hereby Figures 2 and 3 are transverse sections, showing the normal and dumping-positions respectively. Figure 4 showsa modification of my grate. -A represents 'the fi-ont-portion of a cook-stove. B, its fire-place. The fixed portionof my grate consists of a'hor'izontal bar, 0, from which rigidly depend vertical or nearly verticalbars D, which are preferably somewhat finther apart than in an ordinary grate.

Themovable portion of the grate consists of .a series of bars E, fastened to a rock-shaft, F, journalled in the jambs G, and proj ecting through one or both jambs, for convenience of handling.

The front ends of the bars E, occupy the lower. portions of the interstices of the pendants D, and are preferably curved and-pointed upward, as shown at e.

Lugs or rests H, projecting from the jambs, serve to support the front portions of the movable grate E F in its normal position. v (See figs. l and 2.)

The lodgenientof cinders at the rear of the movable v grate E F, in the act of agitating, is prevented'by the I provision of the concave back or guard-plate I, 0011- centric uith the axis of said grate.

The stability of the movable grate when left to itself,

is secured by placing the rock-shaft so far rearward,

as to throw a preponderating weight in front of said shaft. w

When it is desired to sim'plyloosen and discharge the dust and ashes, the movable grate is slightly rocked or agitated, as indicatedhy the dotted lines in fig. 2. Agitation of the grate E F acts in a double way, namely, to detach and shakedown the ashes and to efiectua'll y remove Whatever slag, or other matter may clog the front bars, by the action between them of the curved ends of the fingers e.

\V'hile describing the preferred form of my invention, I reserve the right to vary the same-- in non-essential particulars; for example, a cross-bar or projection, J,

at the bottom of the pendants D may be employed to support the front part of the moving grate, the upward curves or fingers a being omitted. (See fig. 4.)

I claim herein as new, and of my invention- 1. In the described combination, with aseries of pendent front bars I), the seriesof interposed bottom bars E, upon therock-s'haft F, substantially as set forth.

2. In combination with the elements of the preceding clause, the upturned fingers e of the movable bars E, for the purpose designated.v

3. The arrangement of pendent bars D, rock-shaft F, movable bars E, and rests H.

4. In this connection, the provision of the guard I, as and for the purpose explained.

In testimony of which invention, I hereunto set my hand.

CHARLES TRUESDALE.
