ABSTRACT:
The present invention comprises a device that is clamped to the pool table slate through the opening in either of the table's side pockets. The invention also incorporates a threaded shaft which passes through a threaded element to which the principal portion of the device is attached. The lower end of the threaded shaft is fitted with a pilot pin. The pilot pin engages a pivot point formed within the upper surface of a device that is clamped to the pool table edge at the site of the opening of the side pocket. The other end of the threaded shaft is fitted with a handle for rotating the shaft. Depending on which direction the shaft is rotated, the slate can either be raised or lowered.
