TO ALL WHOM IT MAY' CONCERN:

Be it known that I, ALnaanT BROWN, of the city.of Troy, in the county of Rensselaer, and `Stato of New I y declare that the following drawing, and the letters of i York, have invented a new and useful Improvement in Stove Grates; and Ido hereb is a full and exact description thereof, reference being had to the accompanying reference marked thereon.

Figure 1 shows a plan of the grate and frame.

Figure 2 s a plan of the frame with cross-bar and centre.

Figure 3 shows the under side of the grate when detached from the frame.

Figure 4 shows a cross section at line A Ain fig. 1.

In the centre of' the grate B, on the under side, is the concave cavity C, in exact form to admit a half globe or ball. vPermanently attached to the frame F, and crossing a. little one side of the centre of its area, is the cross-ba1-,G-, and to the centre of said cross-bar is attached the convex centre E, which` is made to fit into the cavity C; upon this centre, E, the grate rests, and is made to revolve right and left, to sift down tlic:ashes, elle., which collect above it, in order tokeep the grate from falling off its centre, E, when dumped, or when turned in a perpendicular position, it was necessary to cnt the slot H, in the convex centre E, for the cross-pin I, which is attached to the grate directly across the cavity C, to rest in. This cross-pin lholds the `grate to its centre when dumped, as shown in iig. 4, by the red lines. It will be observed that by turning the shank J, thc grate can be dumped at any point of its sphere of movement, which is quite an accomplishment, as it saves the finding any exact point at which it can be dumped, as is necessary in other gratcs of the kind. It i that the bar G should be permanently secured to or cast place, to secure the harmonious workingof the grate.

1. The permanent bar G, in co the purposes set forth.

2. I claim the cavity C, in combination with the crossspin I, and the convex centre E, as and for the purl poses set forth.

s necessary` on to the frame F, in order to hold the centre E inl .e mbination with the frame F, and convex centre E, or equ'ivalents, as and for 3. I claim the grate B, working upon the centre E, so arranged as to dump on a line withthye shank J', at any point within the sphere of its movement, as and for the purpose set forth. L
