Abstract: A pool cue adapted to be used in the game of pool may include a butt plate member, a butt sleeve member being detachably connected to the butt plate member, and a wrap member being detachably connected to the butt sleeve member. The detachable connection between the butt plate member and the butt sleeve member may be a threaded connection, and the detachable connection between the butt sleeve member and the wrap member may be a threaded connection. The butt plate member may include a bumper member, and the butt sleeve member may include a double female connection to provide an interchangeable sleeve member. A first ring may be positioned between the butt plate member and the butt plate sleeve member, and a second ring may be positioned between the butt plate member and the butt plate sleeve member.

Abstract: The lighted ball includes a spherical housing having a transparent portion, a circuit board mounted in the spherical housing, a on-off switch to detect an impact of the spherical housing and a lamp to flash in response to the impact of the spherical housing. The on off switch includes a first vibration switch and a second vibration switch which is positioned an angle with respect to the first vibration switch, and the lamp includes a first light emitting diode and a second light emitting diode which is positioned at an acute angle with respect to the first light emitting diode. The angle may be approximately 90°. The first light emitting diode may be a different color than the second light emitting diode, and the spherical housing includes a controller to receive signals from the on-off switch.
