Abstract
Abstract A cue tip mounting for glueless attachment of a cue tip to the end of a cue stick, comprising a hollow ferrule adapted to receive the tip end of a cue stick, and provided with outwardly extending barbs constructed to be forced into the material of the cue tip, each barb having an enlarged head portion at its outer end terminating in a substantially knife edge, adapted to be interlocked with the material of such a cue tip, the barbs being symmetrically disposed in spaced relation with respect to the ferrule axis.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
253 words
A cue tip mounting for providing a solely frictional attachment of a cue tip to the end of a cue stick, comprising a hollow ferrule having an axial bore therein opening on one of its ends adapted to receive the generally complementary-shaped end of a cue stick, the opposite end of said ferrule having an end face of a size to receive the cooperable end of a cue tip, a plurality of elongated barbs extending spaced outwardly from the tipreceiving end face of the ferrule in symmetrical relation with respect to the ferrule axis, with the exposed length of the respective barbs being sufficiently less than the corresponding thickness of the cue tip that said barbs cannot pass completely through the cue tip under normal usage, each of said barbs having its said exposed length comprising a triangular prism head with the top edge being a straight line edge, the base of said head having beneath it a segment having its outer surface composed of two inclinations extending in diverging directions, one of said inclinations being flared upwards to mate with said base and the other of said inclinations flaring outwardly and downwardly to form a shoulder which seats on the outer end of said ferrule, said line edges of said barbs being arranged in symmetrical relation with respect to said ferrule axis, and each of said barbs having an elongated mounting portion embedded in and rigidly supported by said ferrule, said mounting portion being of reduced cross-sectional area compared with said shoulder.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
27 words
A cue tip mounting according to claim 1, wherein three barbs are provided, with their respective free end edges extending tangentially with respect to a common circle.
Claim 4
Dependent Claim
39 words
A cue tip according to claim 1, wherein said ferrule is constructed of plastic and said barbs are constructed in the form of separate members having their inner mounted ends individually embedded in the end of the plastic ferrule.
Claim 5
Dependent Claim
24 words
A cue tip mounting according to claim 1, wherein said barbs are integrally connected with a common base member to form a unitary structure.
Claim 6
Dependent Claim
35 words
A cue tip mounting according to claim 4, wherein said base member is disposed within the bore of the ferrule and adapted to seat on the end of a cue stick inserted in the ferrule.
