## Background
TECHNICAL FIELD
The present disclosure relates generally to billiards. More particularly, the present disclosure relates to a cue tip chalk block saver.
BACKGROUND
Billiards is a game played by many people worldwide. Prior to or during the game, a player often applies a block of cue tip chalk to a tip of a billiard cue. During such process, many players hold an exposed portion of the block against the tip and then rotate either the cue or the block to transfer a desired chalk coating onto the tip. The rotation forms or expands a dimple, which keeps the tip centered on the exposed portion of the block and facilitates first few uses of the block if the block is new.
As the block is repeatedly applied onto the cue, the dimple grows deeper and its depth eventually renders the block practically useless for experienced players. However, such block is not really used up. Rather, the block generally contains a substantial amount of unused chalk, often as much as or more than has been previously used.
Although individual cue tip chalk blocks are not particularly expensive, with growth of billiards as a popular form of entertainment and accompanying rise of chains of billiard establishments, cumulative replacement of such blocks incurs a significant operating expense. At least operators of such establishments would benefit from a technology for effectively extending operational life of a cue tip chalk block as such extension would cumulatively provide a potentially large and welcome cost saving.
Accordingly, an effective way of extending operational life of a cue tip chalk block is desired.

Column 23 is turned upside down. Column 23 can be hollow or full. Column 23 includes a lower base 29. Lower base 29 includes a blade 28. In an alternative example embodiment, column 23 includes blade 28 without lower base 29. In another alternative example embodiment, column 23 includes blade 28 without lower base 29 and blade 28 is configured to allow chalk particles to pass past blade 28 into a body of column 23 when column 23 vertically moves to create a dimple. Although blade 28 is cross-shaped, blade 28 can be shaped otherwise, such as star, triangle, circular, rectangle, trapezoid or linear or any combination of the foregoing shapes. Blade 28 projects away from lower base 29. Blade 28 is configured to bore similar to dimple 12.
FIG. 11 is a cross-sectional view of an example embodiment of a column with screw threads according to the present disclosure. Some elements of FIG. 11 are described above with respect to FIGS. 1-10. Thus, same reference characters identify same or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication.
Within opening 22, platform 21 includes a screw thread 30 of internal screw thread kind. Column 23 includes a corresponding screw thread of external screw thread kind. Upon application of a rotational force, column 23 moves via screw thread 30 with respect to platform 21 in a vertical direction substantially perpendicular to platform 21. Upon contacting side 14, blade 28 bores a dimple within block 11. During the vertical movement of column 23, particles bored from block 11 are pushed sideways and eventually fall off a top edge of at least one of walls of holder walls 16.
FIG. 12 is a cross-sectional view of an example embodiment of a column coupled to a spring according to the present disclosure. Some elements of FIG. 12 are described above with respect to FIGS. 1-10.

Column 23 is coupled to a coil spring 31 biased to maintain column 23 in a position column 23 was in prior to the application of the force. Within opening 22, platform 21 includes a plurality of projections 32 projecting toward column 23. Column 23 includes a band 33 set on column 23 between projections 32. Upon application of a substantially vertical force, column 23 moves with respect to platform 21 in a direction of the force. Via an upper projection of projections 32, band 33 restricts upward vertical movement of column 23. Via a lower projection of projections 32, downward vertical movement of spring 31 is restricted. Thus, blade 28 is effectively prevented from tunneling through block 11 to connect to dimple 12.
FIG. 13 is a perspective view of an example embodiment of another usable dimple on an opposing side of the cue tip chalk block in the cue tip chalk block holder according to the present disclosure.
Some elements of FIG. 13 are described above with respect to FIGS. 1-12. Thus, same reference characters identify same or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication.
Cue tip chalk block holder 15 is removed from cue tip chalk block dimple former 20. A new dimple 34 is bored within block 11 is clearly visible. Hence, operation life of cue tip chalk block 11 is effectively extended as block 11 can still be used at least by experienced billiards players.
FIG. 14 is a perspective view of an example embodiment of the cue tip chalk block dimple former according to the present disclosure. Some elements of FIG. 14 are described above with respect to FIGS. 1-13. Thus, same reference characters identify same or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication.
At least two of platform walls 25 are parallel and each includes a plurality of grooves 26 partially protruding through the at least two of platform walls 25. Shafts 18 travel within grooves 26 when block holder 15 is inserted into the platform walls interior space. Block holder 15 fits within the platform walls interior space when column 23 moves.
