Division B.

To all who-m 'it' may con'cm:

Be it known that I, HUGE .of the city, County, and State of New York, have invented a new and useful Improvement in` i Billiard-Cushions; and I do hereby declare the -`following to be a full, clear, and exactdes'crip tion of the same, reference being had to the acccmpanying drawings, forming part of this' specification, iu-whie`-- i i Fi gure 1 is a trasverse section of 'a billiard cushion involving myi'veutiom. i Fig. 2 is fa horizontal section of the same; v

The same part will be fo d designated in V the several figures, by the same letter of In the construction or manufacture of billiard-cushions it has been customary'to make, the cushion of vulcanized' india-rubber, and; this material'has for years 'superseded all others in the 'manufacture of cushion-strips for bil1 iard-tables.

Soon after the introduction into use of tuldeep indeutation of the ball into the, face 'of the cushion, and the consequeut too great impairment of the augle of reflection; and'prior to-my invention miliard-table cushions have been made of vulcaized india-rubber, with'a facig in front and between the india-fbbe'r tdthe cloth cover-ing, made of steel wlale ne, much harder than the' rubber body, so that while the ballin striking would not be permittd to embed itself in the cushion and thus destroy the eorrcctness of the angles made, its force of impact would be dissipated'through the medium 'of the elastic but harder facingstrp over aconsiderable extent of thesurface of the 'so'ftr rubber body in re'ar of the faein gstrip, and it would be causedto rebound from the cushi cn not only at a more correct angle, i but with more force-than'if impelled against theface of 'the softrubber body. But in all cushious made prior to my inven- .tjon involving the combination with .the soft rubber body of some sort of harder facing ma-.-

W. COLLENDEE,

qork, and 'other materials flexible but fterial, the fae-hardening strip was either merely placed against the surface ot the rubber body `and held in place' by the cloth covering' of ,the cushioi, or was held in place by some; means of securement to the cushion-seat.

*My invcntion' has for its object the productiorof a rubber eushion with a hardened face,

in which cushion the rubber body and face-- liardening strip shall be united by the embedment of the latter in the material of the former,

and without either securing the face-hardening s'trip'to the cushion-se'at 'or employing the covering-cloth or any other `auxiliary to eii'e'ct' the retention together in a proper man-ner of r 'the-two elements composing the cushiom and to thisend and object my invention consists in a billiard-cushion composed of arubberbody `and-a face-hardeninf strip of steel or other suitably hard and elastic material, the facehardeiingstrp beingseated in a cavity molded in the cushion for its reception and reteuton, 'as hereinaiter more fully described. 4

i -To enable others skilled in the art -to make and use my inventi'on I will proceed to describe the construction and operation of a cushion embracing it. In the drawing, A, Figs. 1 and 2, represeuts the cushion-seat of a billiard-table of usual construction; B, the elastic block or strip of -rbber forming'the body or back of the cushion.' C is a steel. strip, having the rubber molded around it by placing the steel strip iii the mold in which the rubber is vulcanized,`

which method' of manufacture 'will be found 'fully described iu another application for Letters Patent filed simultaneously with this, and

which, therefore, need not be further e'xplained herei. i

It is desirable, when the cushion is thue constructed, that the rubber which covers the face of the steel strip should be uearly transparent,- or so thin that the ball shall not have a chance to embed itself to an extet which' will prevent its 'performing properlycorrect angles 'to fuifill'the requirements of thegame r v By my inventiou the use of, cement, nails hnges, &(3., for the securement of the ,face

hardenng strip is made .uunecessary, and no cloth covering to the comparatively-hard substzmce in proper relative position to the' softer rnbber body is needed.

It also 'enables me to produce a cu'shion in which is overcome or avoided the disagreeable bang heard when the ball comes in. contact with a fnee-hardening strip fastened by secur- .iug devices at either its lower or upper edge.

It likewise enables me, without trouble of cementing, to face the front of the steel or other equivalent substance with a. thin facing of india-rubber, which will deaden the sound of the steel strip and gripe the ball sfficiently to give greater effect to twistingshots, nud at the same time prevent the bell sliding oti" ntnn inperfeet nugle instead of a proper one when ;played against the oushon at a very &cute angle.

Besdcs all the advantages a-scribed to the cushion in use and efi'eot, my improved cushion may be made with less trouble and expense, since the larder and softer substances may be adjustcd and united With greater convenience as well as acouracy.

' the art of making cushions.

I do not make any claim I'thS application to the manner described of uniting the parts i. e., by putting them together' in the Inold and then vulcanizng the rubber-as this constitutes the subject matter of a separate claim by me in another case to an improvement in Neither do I claim a cushion having& rub ber body and a steel or other hard facing combined in any of the previously-kno'wn ways; but e v What I claim as my inventiomand desire to secure by Letters Patent, is 'f A billiard-oushion composed of a rubber body and a faoe-herdenin g strip, the letter being' arranged and held in a oavity molded in the forrner, substztnti ally as set forth.
