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.

Abstract: A billiard cue having a separate handle and shaft utilizes a quick operating connector to join the handle and shaft. The connector consists of male and female sections which are secured in the ends of the handle and shaft. The male section contains a cylindrical bar having an accurately machined diameter which snugly fits into a cylindrical cavity of the female section which is slightly oversized with respect to the male bar's diameter. The male bar and female cavity are axially aligned in the cue sections, and the bar engages the cavity over a linear distance sufficient to ensure accurate alignment of the handle and shaft when joined. Two flats at the end of the male bar provide a reduced diameter portion of the bar tip which fits between partial bulkheads within the female cavity, allowing insertion of the bar into the cavity.
