Abstract: A motor device utilizing gravitational and magnetic forces in conjunction with a manual user input of energy. The motor device includes a support frame configured to support a plurality of L-shaped magnetic strips with an axle disposed in a horizontal orientation thereacross. A plurality of levers are mounted to the axle by a linear bearing having an arm slidably disposed therein. The arm has a magnet at each end that is repelled by the magnetic strips, causing the repelled end of the arm to slide through the linear bearing and elongating the opposing end of the arm. This creates an unbalanced fulcrum thereby rotating the arm. As the arm of the first lever rotates, the axle rotates causing all subsequent levers to rotate thereby driving the motor.

Abstract: A combined chalk line and articulated level device (10) including a base member (20) having an enlarged vertical mounting face (22) that is fixedly connected to a conventional chalk line dispensing member (30) having a quantity of chalk line (31) that is releasably engagable with an articulated level unit (13) including a bubble level member (40) affixed to a mounting plate element (41) that is pivotally connected to the base member (20) and operatively associated with a roller bobbin (48) to maintain a portion of the quantity of chalk line (31) parallel to the longitudinal axis of the bubble level member (40).
