  • Patent number: 5328411
    Abstract: A billiard cue chalk holder (1) having a closed bottom (6), an open top (2), side walls (3) and a magnet (6) secured to the bottom (6). A chalk block (11) can be inserted into the open top (2) and held in a pressure fit between the side walls (3) of the holder. The chalk holder (1) with the chalk block (11) can then be attached by magnetic attraction to almost any metal surface, such as a plate under a billiard table or a key chain. The chalk holder (1) can also be combined with a belt or shirt clip (14) so it can be attached to a player's belt or shirt pocket during play. The belt clip (14) to which the chalk holder (1) is attached may also contain optional accessories, such as knife (20) for trimming and/or a rasp (21) for filing a tip of a cue stick. This invention prevents the loss of the chalk and eliminates the mess associated with keeping chalk on the billiard table.
