BILLlARD-CUSHION.

SPECIFICATION forming part of Letters Patent No. 468,076, dated February 2, 1892.

Application filed June 26,1891- Serial No. 397,573. (No model.) I

To all whom, it may concern.-

Be it known that I, FREDERICK 1L BRIGGS, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Billiard-Cushions, of which the following is a specification, reference beinghad to the accompanying drawings, in which- Figure 1 is a sectional view of a cushion embodying my invention. Fig. 2 is an enlarged diagram illustrating the difference between the old cushion and my improvement.

My invention consists in the combination of a billiard-cushion having a swell back of its front upper corner with a round wire embedded in the cushion close to the apex of its front upper corner.

Heretofore, as illustrated by the dotted lines 1 and 2 in Fig. 2, the round Wire (indicated by the dotted circle Z) has been embedded at a considerable distance from the apex of the corner formed by the top and front sides of the cushion midway between those sides. The objection to this construction is that the flexible lip formed by the apex of the cushion is curled back before the force of the ball is resisted by that part of the slanting face of the cushion which is backed up by the round wire. To reduce this lip to the smallest extent it would be necessary to put the wire at the apex; but as that is unpractical I place the round wire I) much nearer the front face than usual and in a position where it would protrude from the top of the cushion were the cushion flat on top, and then build up the cushion along the top and parallel with the front upper corner, as most clearly shown in the diagram,in which that partof the rubber shown above the dotted line is added to enable me to put the round wire near the apex without having it protrude from the top surface.

It will be obvious thatonly that portion of the added rubber marked a in Fig. 2 is essential for the purpose of my invention; but in order to better support the cloth with which the cushion is covered when in use I prefer to build it up as shownthat is, across the whole top surface-instead of building it up at a only.

\Vhat I claim as my invention is A billiard-cushion having a swella along the upper side of its front corner and a round wire Z) parallel with and close to the front upper corner and covered by the swell a, the front face of the cushion being sharply undercut to present an edge to the ball, and the wire being in substantially a horizontal plane with the apex of the corner, substantially as and for the purpose set forth.

FREDERICK ll. BRIGGS.
