STOVE-GRATE.

SPECIFICATION forming pere of Lettere Patent No. 293,296, aerea February 12, 18er.. Application filed May 14, 1883. (No model.)

of Massachusetts, a citizen of the United States,

have invented a certain new and useful Improvementof Stove-Grates, of which the following is afull, clear, and exact description,

reference being had to the accompanying drawings, forming a part of this specification, in

explaining its nature, in which- Figure 1 is a plan view of a grate having my improved construction. Fig. 2 is an end elevation thereof. Fig. 3 is a vertical section on the line x 00 of Fig. l. Fig. 4e illustrates a modified form of the invention, wherein only the upper portion of the grate is used. Fig.

5 is a vertical section upon theline yy of Fig. el.

This invention is an improvement upon that described in my Letters Patent No. 229,852, dated July 13, 1880. The especial form or shape of the grate described in said patent is circular, and my present invention relates to means whereby I am enabled to use substantially the same principle of construction therein described in a rectangular or square grate; and it consists in various details of construction whereby this result is accomplished.

Referring to the drawings, A4 represents the grate-frame; c, the front and rear bars of the main grate; c', the end bars thereof. These.

front and back and end bars Vare pivoted to each other at chaud the end bars are pivoted to the grate-frame A and to the crosspiece or plate ci at at `Each of the grate-bars has projections or fingers c5, extending downwardly and inwardly to the opening B. vThe corneriingers, a, are shaped as represented in Fig. l, so that the movement of the grate cannot be interfered with by means of coals or cinders lodging between the fingers at the corne-rs.- By means ofthe lever or arm B', or in any other desirable way, the grate'is reciprocated laterally upon the pivots a4. This causes each ofthe back and front and ofthe end bars to be moved in opposite directions, and a very effective shaking action is thus provided. `Of course, the opening B may be-nearer the back of the grate, as represented in the drawings, or it may becentrally located, or at the front. I prefer generally, however, as the front portion of the fire is more easily reached by the more inclined than those upon the front, thereby throwing the opening B toward the back, as by so doing a smaller support is provided for the lire at the back, and consequently, upon a reciprocation of the grate, the ashes at` thatportion of the iire will settle more rapidly upon the under grate, and thus .clear the fire more quickly than if the iingers or projections were longer and less.inclined, and the back: of the fire will therefore require less attention.

Below the opening B, I arrange the under grate, G, which may be solid, as represented in the drawings, or may have openings across it. It preferably is pivoted to dump toward the front of the ash-pit, and it is supported by the cross-bar or'rod b, the ends of which form pivots b, which are supported by the poker, to make the fingers upon the back bar brackets b2, attached to the grate-frame. This l grate is dumped or turned by means of 'a lever attached to one end of the rod b., and an arm which extends from the end of the lever, preferably to without the stove, through a slot in the casing,.or in any other desirable way. i

Between the lower and the upper grate is the anti-clinlrer space D. There may be arranged between the bars a a of the grate and the grate-frame a space, e, so that the uppen and lower surfaces of the end and back bars shall not come in contact therewith, in which case the frame may have projections c', extending downwardly and upwardly therefrom that shall come in contact with the upper and lower surfaces ofthe grate-bars.

I do not confine myself to the especial means for connecting or pivoting together the ends of the bars, neither do I limit myself to the exact method of hanging it specified, and I may use any mechanical Aequivalents for the specific methods herein described without departing from the spirit of the invention. It is ofcourse obvious that by reducing the size of the opening in the upper grate the lower grate may be entirely dispensed with.; but I do not prefer this construction. 4

In Figs. 4e and 5 the iingers c5 of the upper -grate are shown extended very nearly across the opening d3, and they may be shaped as shown in Fig. 3that is, the upper portion thereof may be inclined and thelower portion IOO ,ables me to dispense with the lower section, 0, of the grate.

horizontal, as desired, or they may be entirely inclined or horizontal. This construction en- I am aware of the Patent No. 34,731, to Brown, dated May 25, 1862, and I do not claizn anything therein described; nor do I consider that it contains the features of my invention, in that it does not describe a grate having four bars pivoted 4together at their ends and to the grate-frame, as above described, and having iingers which project inward therefrom to form the hre-supporting surface. It

will be noticed that this construction divides the grate into four sections-namely, the front and back and the two end-and that each section has a movement in a direction the reverse of the movement of the one opposite it, and that, therefore, by this movement, the re is Well-broken and shaken at the end as well as at the center.

Having thus fully described my invention, I claim and desire to secure by Letters Patl ent of the United Statesl. Astove-grate havingthe parallel sidebars, a, and the parallel end bars, a', thev end bars being pivoted to the frame, of the grate, as described, and the side bars being pivoted to the end bars at c2, the said bars having the fingers a5 projecting inwardly therefrom, all substantially as and for th e purposes described.

2. A stove or furnace provided with a rectangular or square grate, consisting of the lingered bars a a', surrounding the opening B, adapted to be reciprocated, as speciiied, and the grate C below said opening B, capable of being tipped toward the ash-pit door, and a clearing-space, D, between the upper surface and the lower surface of the upper grate, substantially as and for the purposes specied.

3. The combination, in a grate, ofthe fingered grate-bars a a', pivoted to each other and to the grate-frame, as specified, surrounding the opening B, and adapted to be moved or reciprocated in relation to each other as indicated, with the grate C below said opening B, all substantially as and for the purposes described.

4. In a grate, the combination of the fingered bars a fa, pivoted to each other and to the grateframe surrounding the opening B, the fingers c of the back bar being more inclined than those f ofthe front, and adapted to be moved or reciproeated in relation to each other as indicated, with the grate C, arranged below said opening B, all substantially as and for the purposes described.
