ROBERT HENEAGE, OF BUFFALO, NEWYOBK, ASSIGNORTO'BREED, AND` COMPANY, OF SAME PLAGE.

Letters Patent N5. 80,410, ma July 2s, 186e.

IMPROVEMENT 1N stirs-rames( TO ALL WHOM IT MAY CONCERN:

Be it known that I, ROBERT HENEAGE, of the city of Buti-aio, county of Erie, and State of New York, have invented a certain new and useful Improvement in Slates; and I do herebydeclare that the following is a. full and exact description thereof, reference being had to the accompanying drawings, making part of this speciication.

Figure I shows a slate provided with my improvement.

Figure 2, a perspective view of one corner of the frame, and its binding-cushion detached.

Figure 3 is a central vertical longitudinal section of the binding-cushion.

Like letters of reference indicate corresponding parts in the several figures.

My invention consists in combining, with the corners of the slate-frame; India-rubber sockets or mats, which serve the double purpose of cushions, to prevent shock, and hinders, to retain the parts of the frame in place.

AIn the drawings, A indicates the plate of siate-stone, and B B B B the four wooden sides forming the frame.

The corners e e of the frame are made rounding, and at each side'are provided with notches, a a, as clearly shown in fig. 2.

Over the corners are stretched rubber rnats or sockets C O, made of suitable thickness, and provided inside with projecting tongues or catches b b, that catch in the notches ct a, and outside with nipples c c, that form the points oi' contact with any exterior surface.

I am aware that' blocks of rubber have been before set into siate-frames, for the purpose of cushioning the same, and preventing shock in contact with any outside body. My arrangement serves a further purpose, fort while this same effect is produced, I am enabled to bind the ends of the frame together bythe sockets, without the use of the ordinary pin that passes through the ends', Acoupled by socket and tenon. Thus the parts ofthe frame can be readily detached when desired.

(An additional advantage is produced in enclosing the whole corner of the frame, thereby securely shielding it from concussion.

What I claim as my invention, and desire to secure by Letters Patent, is

The rubber mats D D, provided with the catch'es'b'b and nipples c c, in combination with the rounding .corners e e of the slate-frame, having the notches a a, the whoie arranged as described, and operating in the mannerand for the purpose specified.

In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.

ROBT. HENEAGE. Witnesses:

J. R. BRAKE, LYMN P. PERKINS.
