Abstract

A jump cue stick for use in the game of billiards having a first and second hollow shaft members that are releasably connected and very light weight, the jump cue stick does not employ a conventional wood handle or wood shaft but has a carbon/graphite handle end and a carbon/graphite shaft. The jump cue stick of present invention has one embodiment for causing a struck cue ball to be jumped over a obstructing ball and having an overall total weight of less than one half of a conventional jump cue stick and by elevating the handle end of the jump cue to an appropriate height, which is higher than if a conventional jump cue were used, and striking the cue ball at an appropriate angle with an appropriate amount of force enabling the player to facilitate the ball-jumping effect from a much closer distance to the blocking balls.

Claims

exact text as granted — not AI-modified
1 . An article of manufacture for a Improved Segmented Jump Cue stick comprising:
 A very strong and improved segmented jump cue stick being of ten parts and comprising an annular and elongated progressively tapered body, specifically designed for causing a pool cue ball to jump and wherein said jump cue stick comprises;   A handle end shaft (A) being of said stick and having a shaft connecting end for being releasably connected to end of shaft (B); and   A shaft (B) having a connecting end and a striking end;   
     A ferrule and tip assembly on shaft (B) being the end most portion of said stick wherein said ferrule and tip is secured to said stick at the striking end of said stick;
