SPECIFICATION forming part of 'Letters Patent No. 260,809, dated July 11, 1882. ppllcation filed March 10,1882. (No modelJ 'To all whom it may concern:
Be it known that I, GEORGE W. WALKER, of Malden, county of Middlesex, State of Massachusetts, have invented an Improvement in Grates, of which the following description, in
connection with the accompanying drawings, is a specification.
. My invention relates to grates for stoves or furnaces, and has for its object to provide means for agitating the fuel and shaking out the ashes in a rapid and efficient manner without the use of any ordinary hand-poker.
The invention consists partly in the combination, with the usual grate consisting of a series of bars upon which the fuel is supported,
-of an independent agitating device consisting the fuel thus being agitated over a large surface at one operation.
The invention is shown in this instance as embodied in the dumping-grate of an ordinary cooking stove or range, in which the fuel-sup porting grate-bars are made in a single casting or frame mounted on journals, so as to be rotated from its horizontal position to thus dump or discharge all the fuel that has been supported thereon in a body.
The agitating device also consists of a single casting or frame having'a series of upward projectionsor fingers corresponding in position with the spaces between the bars of the grate, so that when in position beneath the grate the said projections will lie between and below the said grate-bars, and by raising the said agitating device or frame bodily upward the said projections or fingers will be forced into and stir or agitate the mass of fuel lying on the said grate. The said agitating device is in this instance forced up and permitted to descend through the space between the gratebars by a cam or series of cums'on a shaft which is adapted to be rotated by a handle or crank applied from the outside of the furnace, the'said cam being provided with projections upon which the said agitating device is supported, and which, in their rotation, raise the Said agitating device and permit it to descend,as
before described. The main grate or dump-- tating device and the bearing for its operating cam-shaft. Fig. 3 is a transverse section of the entire apparatus near its middle point. Fig. 4 is a transverse section of the grate and cam-shaft, showing the agitating device and one of its operating-earns in end elevation. Fig. 5 is a top plan view of the agitating frame removed or disconnected,'and Fig. 6is an end view of the Same.
The main portion of the grate maybe of any suitable or usual construction, it being shown as consistingof transverse bars a, connected by suitable bridges or webs, b, forming a frame provided with journals d, upon which it may be rotated from its normal horizontal position in order to overturn and discharge the fuel upon it in the usual manner.
Beneath the grate is placed an agitatingframe, e, consisting of a series of transverse bars, f, located between the bars b of the grate, as best shown in Fig. 1, they being connected by bridge-pieces g, forming the longitudinal member of the frame, and Shown as located "beneath the bridge-pieces b of the grate, the
said transverse b'arsf being provided with U- Shaped depressions or notches 2, lying beneath the said bridge portions b of the grate, so as to permit the upward movement of the agitating-frame relative to the said grate, as shown in dotted lines, Fig. 3.
The transverse portions f of the agitatingframe e are shown in Fig.3 and in the middle portion of Fig. 1 as consisting of a series of upwardly-projecting fingers, f; but as shown in Fig. and at the ends of Fig. 1 they consist of a single upward projection, f between and at each Side of the bridge-pieces b of the grate a. The agitating-frame is forced upward IOO (No Mam.) .2 Sheets-Sheet 1.
