  • Patent number: 4151991
    Abstract: A billiard cue chalk cube holder, having a base plate mountable on a flat surface by screws, nails, or the like, is provided with a lockable cover which is internally partitioned to form one or more chalk cube receptacles. The cover has an internal latch which is rotatable by a key to alternately engage and disengage slots in the legs of a U-shaped member attached to the base plate. When the cover is attached to the base plate, the nails or screws securing the base plate to the supporting surface are completely concealed, thereby discouraging theft of the chalk cubes.
