TO ALL PERSONS T0 WHOM THESE PRESENTS MAY COME:

Be it known that I, JOSEPH A. VEA'ZIE, of Boston, of' the countyroi` S-uolk, and State of Massachusetts,

have invented a new and useful Improvement in Billiard-Cue Tips; and do hereby declare the `same to be fully described in the following specification, and representcd'in the accompanying drawing, which denotes a section of a cue-tip, as made of strata of leather and vulcanized India rubber, and in other respects in accordance with my invention. i

Common cue-tips are usually made of leather, and especially of sole-leather. While in use, they soon become induratcd and worn smooth, so as to require chalk to be rubbed on them to give them what billia^rd-l players term a proper hold otgthe ball. It is very desirable to avoid such use of chalk, on' account of the marking of the cloth of the billiard-table by it, slch requiring frequent cleaning, and consequent wear of the cloth. r

l My invention is designed to do away with such employment f chalk. To such end I substitute for the leather tip one made of strata or layers of leather and India rubber, preferring what is termed vulcanized India. rubber, such being as shown in thedrawingyin which a a denote the layers of leather,'and` b b those 0f India. rubber, they being arranged one en the other, and cemented together. The outer layer or sheet which is-to-` operate directly against a. billiardball while the cue may be in use, is tobe coated with a composition covering, z, composed ofthe following ingredients, in or about in the proportions hereinafter-:set forth.

The-said composition is to consist of caoutchouc, in its normal condition, or vulcanized, fty parts; tanned leather, finely ground, twenty-five parts; refined chalk, fteen parts; erocus, finely ground, five parts; emery, powdered, v'e parts. The rubber is to be Ydissolved in a suitable solvent which will enable it to-mix with the other ingredients, and form with them a paste which may be moulded or' cast in a mould, and, when dry, will be elastic. Sand, gypsum, and pumice-stone may be substituted for the chalk, croeus, and emery, and either of the same may be used with the caoutchouc, or with it and leather without the others, but I'prefer to employ the crocus and cmery with the chalk in making the composition, as I have reason to believe it is productive of the best results when so made. I have discovered that the crocus, when combined or mixed with't'he ground leather, the rubber, emery, andthe chalk, makes the composition better than when chalk' only is used with the leather, emery, and rubberor elastic gum, or vehicle for connect-ing the earthy materials audIground leather. The ground leather is used to temper or deaden the elasticity of the rubber, and the emery is lemployed in a very small quantity, in order to insure held of the ball in carom-strokes, when the two balls to be struck by the ball are nearlyat a right angle with the course of the striking-ball; It will not answer to use much emery intthe composition, on account of its wearing effect on the ballsiand table-cloth. p

I do not confine the ingredients of the composition to the precise proportions as heretofore given, as they may be varied somewhat, without changing the character of the composition, or so as to render it more or less elastic, or give it more or less holding properties, as different players may desire. The whole tip may be made lof the composition composed of India rubber or its equivalent and one or more other materials, substantially as described, but I prefer to make the tip of layers of the rubber and leather, or the equivalent of the latter, and` coat the external layer ofthe tip with a covering of the composition, which may beapplied to it when the com position is in a tacky state, or by cementing the composition when dry to the said outer layer. l

My improved cue-tip will not spread, harden, and batter up, as will a leather tip; and besides, it is more I am aware ot" the composition described in the British Patent, No. 1,809, for the year 1859, such composition being employed for the formation of tips for cues; consequently, I make rno claimto such. Iusehwith the caoutchouc, chalk, and the earthy or metallic substance or substances or equivalents therefor, constituting the said compositlon, a quantity of ground tanned leather, which I employrfor the purpose above spcciiied, and, in consequence, I make a very much better cue-tip.

I claim, therefore, as my invention, the following:

I claim the new or improved composition, substantially as described, in which ground leather is an important -constituent.

I also claim the combination of n layer of such composition and one or more layers or `strata. of leather 'or JOSEPH A. vnAziE.)
