AGITATING FlRE-GRATE.

$PECIFICATION forming part of Letters Patent-No. 535,984, dated March 19, 1895.

Application filed August 18, 1894. erial No. 520,735- (No inodel.)

To all whom it may concern:

Be it known that I, JOHN H. ,GooDFELLow, a citizen of the United States, residing at Lowell, Middlesexcounty, and State of Massachusetts,have invented certain newand useful Improvements in Agitating Fire-Grates, fully set forth in the following specification and illustrated in the accompanying drawmgs.

This invention relates to certain improve: ments in grates for stoves or furnaces and it has for its objects to provide a raking device are attained by means illustrated in the acco1npanying drawings, in which- Figure 1 represents a longitudinal vertical sectional View of a portion of a stove taken on the line m a; of Fig. 1. Fig. 2, represents a top plan view of the same with the fire-pot removed. Fig.3, represents a transverse sectional view taken on the line y y of Fig. 1; Fig. 4, a perspective View of the raking device, detached, Fig. 5, a detached perspective view of one of the hangers by which the raking device is suspended from the grate.

Referring to the drawings,the numeral 1 indicates the walls of the stove, and 2, the fire-pot thereof, which, in the present instance, is rectangular in form. The numeral 3 indicates a rectangular frame located below the fire-pot, within which the grate 4. is'located, and which is provided with seats or bearings 5 for the journals or trunnions 6 at opposite ends. The grate consists of a rectangular frame, having aseries of longitudinal parallel grate-bars which extend above the upper edges of said frame. One of the trunnions projects through the wall of the stove and is flattened or squared for the reception of a key or lever for dumping, as usual.

The upper surfaces of cross bars 20 are lower than the 'upper surfaces of the grate bars, so that the ends of the acute angular projections at the base of the agitating heads may ride over the said cross-bars, and at the same time be below the fuel, the said angular projections presenting to the fuel a wedge :action, giving to it a rising and falling motion when the rake is reciprocated without at the same time dragging the fuel along the grate surface, as would be the case if the fuel rested in the path of said angular projections.

The numeral 9 indicates the raking device. This consists of arectangular frame, having vertical rakes or fingers 10, which are arranged to set and travel in the spaces between the parallel grate-bars. The said grates are formed with triangular heads, the apices of which project above the grate-bars, while the bases thereof set between the bars, for the purpose hereinafter explained. The rakingframe is half the length of the grate, and rests, normally, under one end of the grate.

The numeral '11 indicates aseries of hangers, which are provided with triangular heads, similar to the heads of-the rakes or fingers 10, which project above the grate bars and act at the sides of the grate, similarly to the intermediate rakes or fingers 10. The heads of these hangers are provided with lateral lugs 12, which set and ride upon the upper edges of the sides of the grate-frame. At their lower edges the hangers are provided with projections 13 which'extend through and are suitably fastened.

The rake-frame at its forward edge is provided with a socket 14, to receive one end of the operating-rod 15, which is recessed as indicated in Fig. 1 so as to engage the socket, and permit the grate-frame to be reciprocated by said rod.

The numeral 16 indicates a lever which is fulcrumed to the lower edge of the front of the grate-frame, and which serves to lock the grate against dumping at one side. The nu- Below the grate-frame islocated a frame 18 having flaring sides, which direct the ashes raked from the grate into the ash pan 19.

It will be observed that the transverse bar 5 20 of the grate'frame, forms an abutment to limit the rearward movement of the rake frame, the front bar forming an abutment to limit its forward movement.

At the front of the stove is formed an ash to guard 2], which protects the opening through which the front journal of the grate passes and also the opening through which the 0perating-bar is inserted.

The operation of my invention is as follows:

When it is necessary to rake the fire, the operating rod 15 is inserted through the opening at the front of the grate, and its recessed end is locked in the socket 14 by giving the rod 3,- half turn. Then by reciprocating the rod the raking frame ismoved back and forth,

clearing the ashes from the grate and loosening and distributing the fuel thereon. To dump the grate the handle 15 is first removed and the lever 16 is moved so as to release the front edge thereof, and the grateframe is turned down by means of a lever applied to its projecting journal as usual.

Having thus fully described my invention, what I claim, and desire to secure by Letters 0 Patent, is

1. The combination, in a stove with the grate thereof, of a rake-frame suspended be low the same, by means of suitable hangers adapted to ride upon the upper side edges of the grate frame, and provided with fingers or rakes projecting upwardly between the gratebars and a detachable operating-rod, whereby the said rake-frame may be reciprocated, substantially as specified.

2. The comhination,with astove grate,com- 4o posed of parallel bars connected by cross bars, the upper surfaces of which are lower than the upper surfaces of the grate bars, of a rake frame provided with a series of vertical fingers, having triangular heads extending upward between the grate bars, with their apices above the upper surfaces thereof and the an gnlar projections at their bases below the upper surfaces of said grate bars, and a series of hangers provided with lateral lugs adapted 5 o to set and ride upon the edges of the grate frame, and means for reciprocating the grate frame, substantially as specified.

In testimony whereof I have set my hand, this 6th day of August, 1894,in the presence of two subscribing witnesses.

JOIIN II. GOODFELLOW.
