.description.

In the Letters Patent granted to me October 19, 1880, a metallic'ribbon is shown embedded within an elastic rubber cushion for the purpose of giving greater and equal elasticity to the cushion at all points. The patent aforesaid contemplates the use of a tempered steel ribbon; but I have found by practice that the thin steel cannot be properly tempered and at the same time kept fiat and straight, so that after tempering, in order to fit it for use in the cushion, theplates haveto be hammered by aslow and expensive process.

Mypresent invention has the object-to avoid this expense and trouble connected with the use of the steel ribbon; and it consists in the use of thin brass, which is roll-tempered in sheets to the proper temper and thickness, and

then cut into straight ribbons of the desired width by special machinery.

In the accompanying drawing I have shown a vertical sectional elevation of a portion of the billiard table and cushion with the elastic ribbon applied thereto.

A is the cushion-rail, B is the bed of the billiard-tabla Ois the cushion-socket. D is the elastic-rubber portion of the cushion, and E is the hard-rubber portion thereof. F is the tempered-brass ribbon, having its IOWGIT' tact with the cushion, as shown.

By using roll-tempered brass, as described above, I am able to produce a superior cushion-for billiard-tables at a much less expense than when the ribbon is made of steel, as firetempered springs cannot be produced straight,

and, besides, are not best suited for the purpose.

In place of using a socket-piece of hard rubber for the ribbon, a piece of canvas may be vulcanized in the soft rubber to form asocket. Having thus described my invention, I claim as new and desire to secure by Letters Patent- In billiard-cushions, the embedded metallic ribbon F, formed of ro1l=te1npered brass, substantially as specified.
