Abstract: An extension for use on a cap and especially adapted for use on a vehicle gas cap which has an elongate member dimensioned so as to extend substantially diametrically across the cap. The base member has upper and lower surfaces, and a pair of side edges. A pair of depending side walls extend downwardly from each side edge of the base member. Together, the base member and side walls define a channel which receives and grips a portion of the cap. Securing means can be provided on the cap extension for securing it to the gas cap.

Abstract: A gravity motor which is formed of at least one motor unit which has at least one motor member fixed to an output shaft. The output shaft is rotationally mounted on a housing. The housing includes a guide surface. The motor member is low frictionally longitudinally movable relative to an output shaft. Each end of the motor member includes a weighted follower which is low frictionally movable relative to a guide surface. The rotation of the motor unit will cause one weighted follower to be moved toward the output shaft by the guide surface with the opposite weighted follower of the motor member being moved away from the output shaft. The result is gravity produces an overall clockwise torque on the motor member which causes rotation of the output shaft.
