IMPROVEMENT IN ASH-SIFTERS.

Specification forming part of Letters Patent No. 159,668, dated February 9, 1875; application led April 23, 1874. l

To all whom 'it may concern:

Be it known that I, J oHN H. GooDFELLow, of the city of Troy, county of Rensselaer and State of New York, have invented certain new and useful Improvements in Ash-Sifters, of which the following is a description, reference being had to the accompanying drawing', in which- Figure 1 is a vertical longitudinal section of the front portion of a cooking-stove, showing my invention arranged in its hearth. Fig. 2 is a vertical longitudinal section of my invention, (in the line .fr a', Figs. 4, 5, and 6,) as shown in Fig. l, but removed from the hearth of the stove. Fig. 3 is a front elevation of the same, as shown in Fig. 2, and having a portion thereof broken away. Fig. 4L is a plan view of the same, as shown, Fig-2. Figs. 5 and 6 are plan views of detached pieces of my invention. Fig. 7 is a perspective view, and Fig. 8 a similar view, of a modification of my invention as adapted to a removable ash-pan.

Like characters refer to like parts in the various figures.

My invention relates to that class of devices usually employed in sifting coal and ashes, and is more particularly intended to be arranged and-inclosed in the hearth of a stove, in such a manner as to receive the ashes and cinders that fall or are emptied from the firechamber, and to sift the same before their removal from the stove-hearth.

In the drawings, forming part of this specication, A is a grate formed of bars c, running parallel with each other. Though this grating may be constructed and arranged in any desired and suitable manner that will permit the ashes to readily pass through it, and will retain the cinders during its agitation, I prefer to have it formed with bars arranged longitudinally from front to rear, so as to offer the least resistance to the shovel in removing the cinders therefrom. One end or edge of this grate is hinged to the swinging back-piece B, and when when this grate and swinging piece are made of cast metal, I prefer, on account of its cheapness and simplicity, to form the parts b and c of the hinges as shown, and cast them solid, respectively, with the pieces A and B. The hanging and swinging piece B can be made with a plain solid surface, and may be suspended at its top in any suitable manner; but I prefer, especially if made of cast metal, to form it with a grated or open-work surface, d, similar to the grate A, and to suspend it in its `place by means of the lugs or projections e in the notches f formed in the rear end of the stationary sides O. The end or portion of the grate A, opposite the swinging back B, is supported, by means of the lugs g, Fig. `l, or the pins g', provided with friction-rollers h, Figs. 2 and 3, at or near the lower edge of the forward and inside ends of the sides C, or by a device equivalent thereto, in such a manner as to permit the grateA to be moved back and forth thereon. The front or side, D, opposite the swinging piece B, I construct and arrange so as to permit the forward portion of the grate A to move freely to and fro beneath its lower edge; and in order to prevent the liability of the cinders or coarse particles escaping or wedging in between the plate D and grate A, and interfering with the free movement of the latter, I provide the lower edge of the side D with the fingers i projecting downward, and I prefer in an inwardlyinclined position between the bars, forming the front portion of the grate A. The sta-Y tionary sides O and D of the cinder-pan, when arranged in the hearth of a stove, can be formed permanent with the castings of such stove, or may be formed of pieces fastened in the hearth; but I prefer to make this device removable from the hearth of the stove, and when it is made removable from its place, and the sides C and D are of cast metal, I prefer to construct such sides provided with the fingers 11 in one piece.

In a devicev constructed and arranged as herein described, as of my invention, it is obvious that when the grate A is moved forward it assumes a position similar to that shown in Fig. l, and when it is moved backward it assumes a position shown in Fig. 2, and that the vibration ofthe siftin ggrate between those positions, and as indicated in the drawings, is more effective in stirring up and sifting the cinders than would be the case were the sifting-grate caused to move to and fro in simply a horizontal direction.

In communicating motion to the sifting-v grate, as shown in this device, I employ the rod E, or an equivalent therefor, and When this device is arranged permanently in its place the rod E can be permanently attached to the grate; but when this device is arranged in its place, so as to be removable, the shakin g-rod E, or its equivalent, should be detachable, so as not to interfere with the removal of the cinder-pan.

What I claim as new, and of my invention,

l. The reciprocating siftinggrate A, snspended to the swinging back-piece B, and supported at the front, as described, so that when reciprocated the front and rear ends thereof are alternately elevated and depressed, substantially as and for the purpose hereinbefore described and set forth.

2. The swinging back-piece B, to support the rear of a swinging and sliding grate, and in combination therewith, substantiallyr as hereinbcfore described and set forth.

3. The plate D, forming the front of the cinder-pan or hearth-pit, having the iin gers i projecting between the bars a ofthe swinging and sliding grate A, to clear the same of cinders, &c., in combination with the grate A, substantially as hereinbefore described and set forth.

4. A cinder-pan or hearth-pit, provided with the stationary side Walls, G, and front Wall, D, the swinging back-piece B, and swinging and sliding grate A, in combination with the fire-chamber and ash-pit, substantially as hereinbefore described and set forth.

The above speciication signed by me this 24th day of November, 187 4.

JOHN H. GOODFELLOW.

In the presence of JNO. T. CARROLL, S. I. STRAND.
