Letters Patent No. 98,059, dated December 21, 1869.
STOVB-GRATE.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern.-
Be it known that l, DAVID HATHAWAY, of the city of Troy, in the county of Rensselaer, and State of NewYoi'k, haveinvcnted a new and improved Stove- Grate; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being hereby had to the accompanying drawings, which form and make a part of this, my specification.
The naturc'of my invention consists in so arranging the sliding bars, which form the bed of the grate, that they may part longitudinally in the centre, their outer edges revolving on journals, supported by loops attached V to the bed-plate or stationary frame, their inner edges dropping down into the ash-pit, leaving a clear passage between-said bars for the discharge of exhausted fuel. These bars are again turned into position, (having their upper surfaces in the same hoisizontal plane, even with the'under side of the bedplate, and. passing under the same) by means of a swinging clasp, approaching in form a semicircle, having journals at the ends revolving in loops in the bedplate, the axes of said journals being at right angles, transversely, across the bed-plate and sliding bars.
The inner edges of these bars are supported near the centrehy said clasp, and have a sliding motion thereon.
In the annexed drawing- A,.Eig'.n'e 1, represents the bed-plate, which may be placed in the tire-chamber 0t stoves, ranges, &c., and secured in a horizontal position in the usual manner.
B and O are the sliding bars, which constitute. the bed of the grate, upon which fuel is to be placed.
These bars have, on their outer edges, at each end, the journals marked, respectively, D E F G,
The journals 1) and E (tig. 1) are supported by, revolve, and slide in the loops N and 0, attached to the bed-plate, the ends of the journals passing under the bed-plate far enough to prevent their being thrown out of the loops.
Figure 4 represents a part of the under side of the grate.
The journals F and G are supported by and revolve v on the ends of the. yoke H, which is movable on the pivot K, which is attached to the bed-plate.
These journals slide between and are retained-in their prope lateral position by the nibsniai'ked a; :1:
Figures 5 and'6 indicate more clearly the connection of the journals 1* and-G with the ends of the yoke H.
Figure 3is a vertical transverse section showing the position of the sliding bars and swinging clasp,
when the grate is in its dumped position.
Figure 2 is the swinging clasp, (partially seen in fig. 1,) which act-nates the sliding bars in the opera- I tion of dumping and replacing the grate.
Attached to this clasp, at right angles to its plane and the axes of its journals U and V, is the arm S.-
Oonnected with this arm, by means of the pivot Y,
(fig. 1,) is the rod '1, which has a sliding motion (in the operation of dumping) in the loop J, and is locked therein by means of a notch near the end of the rod, as at P.
\Vhen the rod is in this posit-ion, the clasp is pressed up against the. innerunder edges of the-sliding bars,
holding them in a'horizontal position, nearly touching the under side of the bed-plate, leaving suificient room for the bars to slide freely.
When the grate is in thisposition, (as indicated by fig. 1,) the weight of the sliding bars resting upon the clasp, and acting through the arm S, forces the rod T in the direction of its length, pressing'the notch P firmly against the loop J. In this positionthe plane of the clasp is parallel with the plane of the bedplate.
lock in the loop J; the rod will take the position indicated by the broken lines; the clasp will revolve on itsjournalsU'and-V, in the loops M and It, its plane taking nearly a vertical .position, the inner edges of the sliding bars dropping down into the ash-pit, as in- This operation communicates an oscillating motion to the yoke H, which turns on the pivot K; and the 1 ends ofthe yoke being connected with the journals F and G, of the sliding bars B and G, motion is given to said bars in the direction oftheir length. r
In this arrangement for a stove-grate,
What I claim as my invention, is-- 1. The central sliding barsB O, the outer edges of which revolve on the journals D E and F G, the inner edges dropping down into'theash-pit, leaving a wide openi'pg between said bars, constructed, arranged, and
opera-ting as set forth;
2. Theclasp, fig. 2, in combination with the rod Tand arm S, by which the grate is dumped, and the sliding bars again'replaced in working position, substantially as described.
