Billiard cue with improved tip configuration
Nickname - none received yet. Care to suggest one?
A billiard cue 10 comprises a handle section 12 and a cue tip section 14. This cue tip assembly comprises a ferrule 30, a cue tip insert 40 and a cue tip pad 50. The ferrule 30 and the tip 18 of the billiard cue are cooperatively constructed so that the ferrule 30 fits over and around the outer-most part 20 of the cue tip 18 and seats on an annular land 22 at the base of part 20. The cue tip insert 40 and the ferrule 30 are cooperatively constructed so that insert 40 can be releasably joined to ferrule 30. In this combination of the cue tip assembly 14 and the billiard cue shaft 13, a variety of cue tip pads can be alternately attached to the same shaft 13 (each unique in diameter and/or hardness so as to reduce or enhance cue ball deflection) simply by substituting one insert 40 for another.

1. A billiard cue shaft tip assembly for attachment to a shaft that has a tip end provided with an elongated axial tenon, the tip assembly comprising a ferrule adapted to be secured to the shaft tip end tenon; and a plurality of different size tip inserts, each having an elongated axial tenon adapted to be releasably inserted into said ferrule in juxtaposition with said shaft tip end tenon, each said tip insert further having a head provided with a transverse cue tip pad supporting surface, said head having a lower surface adapted to contact an upper end of said ferrule so as to completely transfer cue ball impact forces from said tip insert directly into said ferrule, said ferrule being so constructed and arranged with respect to said tip inserts that the juxtaposed end of said tip insert tenon and said shaft tip end tenon are spaced from one another a short distance whereby no cue ball impact forces can be transferred between them; each said tip insert having a head providing a cue tip pad supporting surface of a different size for receiving a different sized cue tip pad whereby said tip assembly can provide a variety of cue tip pads for quick and convenient selection and mounting to a single billiard cue by means of said ferrule being secured to said shaft tip end tenon.
2. The tip assembly according to claim 1 wherein said ferrule is fabricated from a synthetic material selected from the group comprising DELRIN plastic and nylon, and wherein each of said tip inserts is fabricated from a synthetic material selected from the group comprising ABS plastic, PVC plastic, and aluminum.
3. The tip assembly according to claim 2 wherein said ferrule is provided with an internal axial passage for receipt of said shaft tip end tenon, said ferrule passage being fluted with axial, longitudinal ridges or ribs for engaging said shaft tip end tenon to secure said ferrule against rotation relative to said shaft tip end tenon.
4. A billiard cue comprising a shaft having a shaft tip end including an axial, elongated tenon; and a tip assembly comprising a ferrule adapted to be secured to the shaft tip end tenon, and a plurality of different size tip inserts, each having an elongated axial tenon adapted to be releasably inserted into said ferrule in juxtaposition with said shaft tip end tenon, each said tip insert further having a head provided with a transverse cue tip pad supporting surface, said head having a lower surface adapted to contact an upper end of said ferrule so as to completely transfer cue ball impact forces from said tip insert directly into said ferrule, said ferrule being so constructed and arranged with respect to said tip inserts that the juxtaposed end of said tip insert tenon and said shaft tip end tenon are spaced from one another a short distance whereby no cue ball impact forces can be transferred between them; each said tip insert having a head providing a cue tip pad supporting surface of a different size for receiving a different sized cue tip pad whereby said tip assembly can provide a variety of cue tip pads of varying hardness and diameter for quick and convenient selection and mounting to a single billiard cue by means of said ferrule being secured to said shaft tip end tenon.
5. The tip assembly according to claim 4 wherein said ferrule is fabricated from a synthetic material selected from the group comprising DELRIN plastic and nylon, and wherein each of said tip inserts is fabricated from a synthetic material selected from the group comprising ABS plastic, PVC plastic, and aluminum in a range of diameters and a range of hardness.
6. The tip assembly according to claim 4 wherein said ferrule is provided with an internal axial passage for receipt of said shaft tip end tenon, said ferrule passage being fluted with axial, longitudinal ridges or ribs for engaging said shaft tip end tenon to secure said ferrule against rotation relative to said shaft tip end tenon.
