'IMPRQVEM EMT n STOVES.

Specification forming part of Letters Patent No. 209,557, dated November 5, 1878; application filed April 9,,1878.

To all whom it may concern:

Be it known that I,JOHN H. GooDFELLow, I

of the city of -Troy, in the county of Itensselaer and State of New York, have invented certain new and useful Improvements in Stoves, described in the following specification, reference being bad to the accompanying drawings,

in which- Figures 1 and 2 represent a vertical section V one end and outside of the fuel-chamber. Fig.

characters refer to corresponding parts in the various figures, Ais the fuel-chamber. B is a cut-off, which may be formed of a plate or of grating, or, substantially as shown, formed of a plate, a, and grating or bars I), and is provided with arms 0 0, extending from the upper and outer portions of thecut-oif around and outside of the adjacent corners of the firebox to supporting-bearings c c at the outside of the end walls, D D,'of the chamber A, all constructed and arranged in relation to the fire-box in the manner substantially asshown, so as to permit. the cut-off B to be moved to and'fro edgewise in the arc of a circle from its position next to and outside of the front side wall, E, of the fuel-chamber to that indicated by dotted lines in Fig. 2 above the fuel-supporting grate, and across, or partly across, the lower part of the chamber A, in such a manner as to form, when in such latter position, a support to the fuel in such chamber above such cut-off, so that when the. fuel-supporting. grate is withdrawn or dumped the ashes and clinkers between it and the cut-off will fall into the receptacle beneath, the thickness of the layer of ashes so removed being regulated by the distance the cut-off B (when in position of dotted lines, Fig. 2) and the fuel-supporting;

grate are adjusted from each other.

nected therewith, as herein described. The

resistance of the fuel in the chamber A is generally sufficient to prevent the cut-off B'fromfalling from its position at the side of the firebox; but to otherwise retain the cutoff in this position, especially when the chamber A is empty, or nearly so, I employ a catch, H, attached at d to the casing I of the stove, and engaging with a notch or projection, e, on the said cut-off, or any device equivalent thereto.

Though the fuel-supporting grate may be constructed and arranged in its place in the stove so as to be removed or dumped in any suitable manner not to interfere with the abovedescribed to-and-fro edgewise movement of the cut-off B, I prefer to construct such grate F withvbearing-lugs J J at or near its side op- G is a shank formed on oneot' the supportposite to the cut-off B, and to so support and arrange it with reference to the chamber A and cut-off B that when such cutoff is caused to move toward the position indicated by dotted linesB in Fig. 2 this grate F can, if desired, be caused to move simultaneously to the position shown in the same figure by means of any .suitable device therefor; but I prefer to operate the cut-off B and grate F simultaneously, by providing the journal J with a fixed arm, K, projecting forward, and connecting it with a strap or link, L, to the arm 0 of the cut-off.

The link L may be provided With a notch or recess, f, to receive a projection, g, on the arm K, so as to be readily disengaged therefrom when the grate F and cut-01f B, and parts connected therewith, are in the position shown in Figs. 1, 3, and 5, to permit the side of the grate F next to the cut-off B, to fall away from the chamber A, as shown in Figs. 2 and 4t, for the purpose of allowing the whole contents of such chamber to fall into the ash-pit below, the link L having suflicient length beyond the recess f to rest against the lug g when disengaged therefrom, so that when the cut-ofl' arm 0, with link L thereto attached, is moved to the position indicated in dotted lines in Fig. i

4, or the grate F is raised to the position shown in Figs. 1 and 3, the link will again engage with the arm K.

I am aware it has been heretofore proposed in a number of instances to support the fuelsustaining grate of stoves at or near its rear edge, so as to permit its opposite side to fall away from the fuel-chamber; and I am also aware it has been heretofore proposed to sup- .port such grate in its horizontal position by means of a catch engaging therewith, neither of which devices do I claim as of, my invention.

What I claim as my invention is 1. In a stove, the cut-off B, constructed and arranged in combination with the fuel-chamber A, substantially as shown and described,

-so that when such cut-off is unemployed in sustaining the upper portion of the contents of the fuel-chamber A while a lower portion thereof is being removed, as herein set forth, the said cut-off can be retained or supported in a vertical, or nearly vertical, position next to and outside of one of the side walls of said fuel-chamber.

combination with the chamber-A, substantially, as shown and described, and provided with mechanism for simultaneously operating said cut-01f and grate, in the manner set forth. 5. The cut-oh" B, grate F, having bearings J J and arm K, or'its equivalent, and connecting-link L, constructed and arranged in combination with the chamber A, and to operate substantially as shown and set forth.

6. The cut-off B, provided with supporting-- arms O G, constructed and arranged together substantially as shown and described, so as to be capable of being employed in combination with the chamber A and its fuel-sustaining grate, in the manner substantially as set forth in the above specification.
