IMPRQVEMENT. IN FIRE-PLACE GRATES.

Specilication forming part of Letters Patent No. 121,699, dated March 19, 1872.

Specification describing certain Improve ments in Fire-Grates, invented by RICHARD. P. SAUsE, of the city of Louisville, county of J eiferson and State .of Kentucky.

-The first part of my invention consists more especially in the tile in the back and the iron plate on which it rests. This plate is made of cast-iron, of any desired thickness, with the end resting on thehearth below, and extending up the whole width as' high as the top of the grate7 with small ribs cast on the upper edge, about one inch or more apart. These ribs are cast on the front side, and project over the edge about one inch, in order to keep the tile in its place. Between each of Athese last-named ribs the plate is perforated with holes, so as to admit air from the back, in order to increase combustion, the air being admitted to the chamberbehind the grate through holes in the-plate under it. The tile which constitutes the upper portion of the back for about six inches above the grate is made straight on the lower edge, where it rests on the plate; but the remaining upper part is made to pitch forward at an angle of about fifty degrees, or suicient to correspond with the height of the arch above, while the eX- treme upper edge of the same is turned back to suit the angle of the iiue, in such a manner as to leave the tile in a circular form over the top and in front, so as to correspond with the opening in the grate-frame, in order to leave the hue-space of equal size across the entire liuc to equalize the draught. This tile is tinted or corrugated in front and on the under side to attract the draught to the sides, in order to equalize the heating-surface, and may be made in one or more pieces for convenience in setting, the side walls being built either of -tile or common fire-brick. l

The second part of my invention consists in the arrangement of the grate, the front part of which is composed of three iiat bars, with points projecting from the lower bar, in order to form the turn of basket-bars, but are not connected with the bottom. This front has a hook at each upper corner, by means of which it is hung to the frame, and likewise hooks at each lower corner, for the pins of the bottom to rest in. This bottom grate is composed wholly of straight bars, except where they form the basket-curve in front, the back ends being connected by a bar about three or more inches from the ends, which are made to rest against the back plate between the ribs, and is thereby held up in such a position as to be susceptible of being raised or lowered, at pleasure, by means of the eccentric below, placed there for the pu-rpose of shaking or cleaning the grate.

The third part of my invention relates to the device for shaking and cleaning the grate, which consists in a small shaft placed immediately under it, working in bearings cast on the lower part of the front, and also through the back plate. This shaft has a small eccentric on the end near the back, which works against a rib ou the under side of the grate, the end of the shaft extending through in front, so as to apply a socket-crank or lever to operate it with, which is done by simply turning it back and forth. This front and back, constituting the grate, when not in use may be folded together and hung on pins placed in the jambs for that purpose, and the summer front put in without hindrance.

The advantages which I claim 4for invention consist, first, in the manner of constructing the grate, which renders it much cheaper and more durable than those now in use; and, when taken in connection with the arrangement of the back and the shape of the tile over it, the amount of fuel consumed in a given time is greatly reduced below that of the ordinary grates in use, from the fact that the tile is so shaped as to distribute the re equally over the whole heating-surface of the front opening, thereby causing the heat to be thrown out into the room with greater intensity. Although this grate is intended exclusively for the use of coal, it is equally adapted to that of wood, by simply placing a sheet-iron plate in the bottom and also by hanging another iu front, so as to admit the air only at the lower part of the front through openings cut in the sheet-iron.

Having thus fully described the nature and object of my invention, a more thorough understanding of which may be had by reference to the drawing- `:Figure l is a perspective view of the grate and frame, showing the general arrangement as seen from the front. Fig. 2 is an end view of the grate, showing the hooks at the ends and the eccentric by which it is operated. Fig. 3 is a sectional view, showing the air-chamber and also the shape of the tile and back plates.

In the drawing, A is the grate-frame, and is made of iron, similar to those now in use. B is the luted or corrugated tile. C is the iron back plate. D D are the air-holes in the upper plate. E E are the ribs on the plate. F F F are the draught-holes below the grate. G is the pin in the jambs to hang the grate on when not in use. H is the fender. J is the front grate. K is the bottom. L is the upper hook on the front. M is the hook or rest for the bottom. N is the eccentric. R is the shaft. O is the crank or lever by which it is operated. l is the air-chamber. Q is the liue.

Having thus fully described the drawing, what I claim as new, .and desire to secure by Letters Patent, is-

1. The tile B, as described, with. its grooves or corrugated channels, in combination with the iron back U, with its ribs E E, and airholes D D and draught-holes F F F below the grate, when arranged, constructed, and operated substantially as and for the purpose set forth.

2. The grate J and K with the hooks L and M, and also the eccentric N with its shaft R and lever O for operating it, when arranged, constructed, and operated substantially as and for the purpose hereinbefore set forth.
