To all whom 'it 'ma/y concern:

'Be it known that I, LQP.

This invention relates to improvements in apparatus for breaking and separating coal, designed to provide a more eicieut apparatus than any now in use.

The invention consists in the arrangement of breaking-rollers, separating-hopper, grate, and screen; also, certain improvements in attaching the spikes to the breaking-wheel, or cylinder, all as hereinafter more fully specified.

parts. 4

A represents a large breaking-cylinder, providedl with spikes B, arranged in suitable bearings in the housings C. v

D represents a hopper, or curb for confining the coal against the action of the wheel, and provided also with spikes to assist the breaking.

This curb is provided with perforations E, to permit the escape of such lumps as are small enough to do so.

These holes may be made of the proper size for any required size of coal, say steamboat-coal, or the largest size used, of broken coal. i

A grate, G, is arranged under these openings, to receive the co'al after passing through them for separat- Similar letters of reference indicate corresponding l ing therefrom a smaller size, while the larger passes over the ledge thereof at H.

The smaller coal,` after passing through the grate G, is delivered upon a screen, I, which may be either ro' tary-or fixed, whereby it is again sized, and the larger part delivered therefrom to a smaller rotary breaker, K, as is also that passing down from the large breaker, Where it may be broken as ne as may be required.

The small roller moves in the direction opposite to that of the L rger one, and may be adjusted to or from the latter, to vary the size of the coal, as may be required.

To facilitate the removal of the spikes from the rollers for sharpening or renewal, 1 set them iu recesses in the shell of the rollers, as shown at L, andv provide the Wedge-headed bolts M, secured by nuts inside thereof to clamp the spikes in place.

Having thus described my'invention,

I claim as new, and desire to secure by Letters v Patent- 1. 'lhe arrangement of the perforated spiked curb O, grate Gtand ledge H, with reference to the spiked breaker A and rotary screen I, as herein described,.for the purpose specified.

2. The combination, with the curb G and stationary or rotary screen I, of the grate G, when arranged substantially as speciiied.

3. The combination, with the breaker A, of the 'breakerK and screen I, when arranged substantially as specified 4. The spikes arranged in the recesses L, and secured by the bolts M, substantially as specified.

L. P. GARNER.
