Cue stick tip application and maintenance tool

## Abstract

A cue tip tool is a cylindrical jig having a longitudinal bore forming its body into a tube that accepts a cue being tipped. The jig body has three equally positioned slots cut through the tubular wall, and the outer surface of the jig has a collar that squeezes the jig against the cue ensuring that the axis of the cue is aligned with the jig. The end of the jig is a cylindrical surface stepped to a larger diameter, and the stepped cylinder is coaxial with the axis of the jig and the axis of the cue. Three auxiliary units configured to separately engage the jig provide for burnishing the end of the cue's ferrule, positioning the cue tip being installed during gluing, and cleaning the cue tip of accumulated chalk debris, while maintaining accurate alignment of the cue tip with the cue's axis.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to accessories for the game of billiards, and in particular to a tool for applying a billiard cue stick tip and for maintaining its condition.
2. Description Relative to the Prior Art
The integrity and condition of the cue stick tip which contacts the cue stick ball during a billiard shot has long been a matter of interest and concern to billiard players. After much experimentation, the cue stick tip of choice is the leather tip, and it is available in a variety of leather materials, shapes and widths. The widths of standard leather commercially available cue stick tips range from 9 mm to 15 mm, usually in 1 mm increments. The player selects a width equal to that of the ferrule of his cue stick, and glues the cue stick tip to the end of the ferrule. The prior art discloses a large variety of tools for use in applying, trimming and cleaning tips. Typical prior art may be seen in the following U.S. patents; U.S. Pat. No. 60,503, “Billiard Cue stick Tip Fastener”, U.S. Pat. No. 4,987,936, “Cue stick Tippers”, and U.S. Pat. No. 5,228,160, “Cue stick Tip Shaping Tool and File Fabrication Method for Use Therewith”.
It is known that for optimum control of the billiard shot, not only the surface condition and body texture of the cue stick tip are important, but the orientation and placement of the cue stick tip relative to the cue stick axis are also major considerations. The present invention provides a novel, simple and effective multi-function tool for precise positioning during installation, and for effective maintenance of a leather billiard cue stick tip.
SUMMARY OF THE INVENTION
A multi-function cue stick tip tool consists of a substantially cylindrical cue stick support jig having a longitudinally extensive bore that fashions the body of the jig into a tube like structure. The bore is dimensioned for accepting insertion of a billiard cue stick whose end is to have a cue stick tip attached or further processed. The jig body is provided with three longitudinal collet like slots through the tubular wall, equally positioned around the circumference of the jig body. A slightly tapered collar riding on the outer surface of the support jig may be positioned along its surface to squeeze the segments of the body of the jig against the surface of the inserted cue stick, ensuring that the axis of the cue stick is held locked in coincidence with the axis of the jig. The end of the jig is a cylindrical surface is stepped to a slightly larger diameter than the body of the jig, and the stepped cylinder is precisely coaxial with the axis of the jig, and hence with the axis of the inserted cue stick. A set of three auxiliary tools configured to engage the stepped end of the jig provide for burnishing the end of the ferrule of the cue stick prior to installing the cue stick tip, supporting and positioning the cue stick tip being installed during gluing, and cleaning the cue stick tip of accumulated chalk debris during use, while maintaining the cue stick tip's surface integrity and symmetrical alignment with the axis of the cue stick.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIG. 1, a cue stick support jig and tightening collar, 10, is comprised of a support jig body, 12, and tapered moveable tightening collar, 14. Support jig body, 12, and moveable tightening collar, 14, are fabricated from a substantially rigid material of plastic or metal. A suitable material is the plastic Delrin®. The support jig body, 12, is provided with a longitudinal bore, 16, extending the length of the support jig body, 12, and the bore, 16, accurately defines the longitudinal axis of the support jig body, 12 relative to the outer surfaces of the support jig body, 12. In particular, a stepped cylindrical surface, 18, at one end of the support jig body 12, is coaxial with the longitudinal axis of the support jig body, 12. At its other end, the jig support body, 12, has 3 slots, 22, 24, 26, (FIG. 2), positioned at 120 degree angles around the circumference extending longitudinally along the jig support body, 12. When a billiard cue stick, e.g. 20, (FIG. 3), whose cue stick tip end is to be processed, is inserted into the jig support body 12, the tapered moveable tightening collar, 14, is positioned along the cylindrical surface with which it is in contact, forcing the segments of the jig support body, 12, formed by slots 22, 24, 26 into firm contact with the billiard cue stick, e.g. 20 and centering the longitudinal axis of the cue stick, 20, along the axis of the jig support body, 12.
Referring to FIG. 3, a first function of the tool of the invention may be understood, that is, the use of the tool in conditioning the face of the ferrule, 28, prior to attaching a new cue stick tip to the cue stick, 20. With the cue stick, 20, aligned with the axis of the jig support body, 12, as explained above, the first auxiliary tool, 30, is inserted into the opening of the jig support body, 12. The first auxiliary tool, 30, is in the form of a plug like cylinder whose surface, 32, is in sliding contact with the stepped surface, 18, and whose front face, 34, may be forced into contact with the ferrule, 28. Since the cylindrical surface, 32, is parallel to the axis of the cue stick, 20, the front face, 34, of the tool, 30, is perpendicular to the axis of the cue stick, 20, and therefore is parallel to the face of the ferrule, 28. The front face, 34, is provided with an abrasive material such as emery or diamond particles so when the first auxiliary tool, 30, is hand rotated by flange, 42, the face of the ferrule, 28, is cleaned and conditioned to receive a new cue stick tip whose axis will lie along the axis of the cue stick, 20.
Referring to FIG. 4, a second function of the tool of the invention for accurately affixing a new cue stick tip to the cue stick, 20, may be understood. As described in the above description of the ferrule cleaning function, the jig support body, 12, is aligned with the cue stick, 20, axis and secured by the tightening collar, 14. A second auxiliary tool, 30′, similarly formed as a plug like cylinder having a cylindrical surface, 32′, is fabricated from a “non-stick” material, such as Teflon®. (In the drawings, different but related elements are identified by the same reference number, albeit the different elements are distinguished by primes. Unprimed elements in the different drawings with the same reference numbers are the same element.) The second auxiliary tool, 30′, serves to guide a replacement cue stick tip, 36, so that the cue stick tip rear face, 38, is parallel to the ferrule, 28, face. This ensures that the cue stick tip will be axially symmetrical with the ferrule, 28, face and cue stick, 20, longitudinal axis, upon gluing the cue stick tip rear face, 38, to the ferrule, 28, face. Upon gluing these faces together, any excess glue will not stick to the Teflon® body of the second auxiliary tool, 30′ leaving the cue stick tip 36 accurately attached to the cue stick, 20.
Referring to FIG. 5, a third function for cleaning and maintaining the cue stick tip's surface during play, is provided. Chalk is used during play to increase the friction between the cue stick tip, 36, and a cue ball, and with use, an unwanted smooth coating of chalk builds up. A third auxiliary tool, 30′′, cleans the cue stick tip surface by abrading the built up chalk, and, importantly, does it without distorting the symmetry of the cue stick tip surface or misplacing the cue stick tip axis from alignment with the longitudinal axis of the cue stick, 20. The third auxiliary tool, 30′′, is a plug-like rigid metal or plastic unit, similar to the first and second auxiliary tools described above, has a cup shaped surface, 40, that conforms with the shape of the front surface of the cue stick tip, 36, and the surface, 40, includes an abrasive material such as emery or diamond particles. As previously stated, it is essential that the cue stick tip, 36, be maintained axially aligned with the cue stick, 20, and therefore the third auxiliary tool, 30′′, is used in conjunction with the jig support body, 12, when used to abrade built up chalk deposits on the cue stick tip, 36. The jig support body, 12, is affixed to the cue stick, 20, and locked in place by means of the tightening collar, 14, as previously described. With the plug-like third auxiliary tool, 30′′, inserted into the jig support body, 12, its cylindrical surface, 32′′, is accurately positioned for sliding contact against the stepped surface, 18, and, accordingly, the cup shaped surface, 40, is in symmetrical alignment for contact with the cue stick tip, 36. By manual rotation of the flange, 42′, the abrasive particles in the cup shaped surface, 40, remove caked chalk from the cue stick tip, 36, surface while maintaining the symmetrical integrity of the cue stick tip, 36, and without disturbing its alignment with the axis of the cue stick, 20.
The invention has been described with reference to specific illustrations and examples, but it will be understood that various modifications can be made without departing from the spirit of the principles and teachings of the invention. Accordingly, the invention is limited only by the following claims.
