BILLIARD CUE Filed DeG. 27, 1935 www ATTORNEYS Patented Mar. 2, 1937 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to cues used in playing billiards, pool or analogous games and resides more particularly in an improved cue tip which may be made up so as to either be permanently affixed to the end of the cue or as an accessory for ready attachment to or removal from the cue.

n Broadly, the invention contemplates a cue tip which is so constructed and arranged as to obviate the necessity of applying chalk to the impact surface for preventing miscues.

More particularly the invention comprehends a cue tip consisting of a body constructed of a yleldable resilient or elastic material provided with a plurality of depressions in and distributed over the impact surface thereof so as to constitute suction cups when engaged with the cue ball and compressed by the impact of the tip therewith in order to prevent miscues caused by slipping or skidding of the tip.

'I'he invention further resides in an improved cue tip of the indicated character which includes means for removably attaching the tip to the end of a cue whereby a player may purchase one or more tips as an accessory which may be readily applied to and removed from a cue.

Other objects of the invention are to provide a cue tip which is comparatively simple in its construction, may be economically produced and which is highly eflicient for its intended purpose.

With these and other objects in view, reference is made to the following specication and accompanying drawing in which there is disclosed, by Way of example, several preferred forms of the invention, while the claims are intended to cover other variations and modications falling within the scope of the invention.

In the drawing:

Fig. l is an enlarged longitudinal sectional View through the end of a billiard cue and through a cue tip constructed in accordance with one form of the invention.

Fig. 2 is an end view thereof.

Fig. 3 is a side view of a modified form of the invention, partly broken away and shown in section.

Fig. 4 is a transverse sectional View taken approximately on the line 4--4 of Fig. 3.

Referring to the drawing by characters of reference, in the form of the invention illustrated in Figs. 1 and 2, A designates a billiard or pool cue and B generally the cue tip which is of the type adapted to be permanently secured by a suitable adhesive to the outer end surface of the cue. The tip B includes a metal core I0 having a flat inner surface II and a convex outer surface I2, the inner surface being provided with protruding spurs I3. The core I0 is encased in a sheath Iii of rubberized fabric with the spurs I3 embedded in the inner flat wall I5 thereof. The outer arcuate wall I6 of the sheath III which is stretched over the convex surface I2 of the core has vulcanized thereto a yieldable resilient impact element I'I preferably of rubber andthe impact surface I3 thereof is formed with a plurality of depressions I9 extending inwardly from the surface and preferably uniformly distributed thereover. In use, the depressions I9 constitute minute suction cups when the impact surface I8 engages with the cue ball and is compressed by the impact of the tip therewith. I'his functions to prevent skidding or slipping of the cue tip with reference to the cue ball and sets up a slight adherence between the contacting portion of the impact surface with the ball thereby avoiding the necessity of using chalk to provide the necessary anti-skid or nonslip action.

In the form of the invention illustrated in Figs. 3 and 4 of the drawing, the tip B is constructed identically with that of the previous form, but in this instance the tip is removably attached to the cue A by means of a contractile elastic sleeve 2|] preferably of rubber, one end of which is secured in surrounding relation to the periphery of the sheath I4 with the remainder of the sleeve extending rearwardly therefrom to define together with the inner wall I5 of the sheath a socket which is adapted to snugly t over the outer end of the cue A. In order to prevent unintentional or accidental displacement of the tip from the cue, the inner surface or periphery of the sleeve 20 is formed with circumferentially extending annular beads 2| which combined with the contractile action of the sleeve securely retains the tip in applied position on the cue. In order to reinforce the sleeve, the same is provided on its outer surface or periphery with circumferentially spaced longitudinally extending ribs 22.

What is claimed is:

l. A tip for billiard cues comprising a rigid core having a convex outer surface and a flat inner surface provided with outwardly projecting spurs, a relatively yieldable sheath encasing said core and in which the spurs are embedded, an impact element constructed of a resilient material secured to the outer wall of said sheath and having a plurality of depressions formed in and distributed over the outer surface thereof to constitute suction cups when engaged with the cue ball and compressed by the impact of the tip therewith.

2. A tip for billiard cues comprising an element constructed of a yieldable resilient material having a plurality of depressions formed in and distributed over the impact surface thereof to constitute suction cups when engaged with the cue ball and compressed by the impact of the tip there- With, and means for removably attaching the tip to the `end of `the cue consisting of a rigid core, a sheath covering said core and a contractile elastic sleeve secured at one end in surrounding relation to the periphery of the sheath with the major portion extending rearwardly therefrom to define together with the inner Wall of the sheath a socket adapted to snugly t over the end of the cue.

3. A tip for billiard cues comprising anelement constructed of a yieldable resilient material having a plurality of depressions formed in and distributed over the impact surface thereof to constitute suction cups when engaged with the cue ball and compressed by the impact of the tip therewith, and means for removably attaching the tip to the end of the cue consisting of a rigid core, a sheath covering said core and a contractile elastic sleeve secured at one end in surrounding relation to the periphery of the sheath with the major portion extending rearwardly therefrom to define together with the inner wall of the sheath a socket adapted to snugly iit over the end of the cue, said sleeve having circumferential beads formed internally thereof.

4. A tip for billiard cues comprising an element constructed of a yieldable resilient material having a plurality of depressions formed in and distributed over the impact surface thereof to constitute suction cups when engaged with the cue ball and compressed by the impact of the tip therewith, and means for removably attaching the tip to the end of the cue consisting of a rigid core having a flat lower surface and a convex upper surface, a sheath encasing said core and a contractile elastic sleeve secured at one end in surrounding relation to the periphery of the sheath with the major portion extending rearwardly therefrom to define together with the inner Wall of the sheath a socket adapted to snugly fit over the end of the cue, said sleeve having circumferential beads formed internally thereof, and longitudinally extending ribs externally of said sleeve.
