Abstract: A hand held, oscillating razor for wet shaving which comprises an internally operated eccentric for forcibly, rapidly vibrating the cutting blades. Preferably the razor comprises an elongated, generally tubular housing adapted to receive a carriage which mechanically secures a rotatable eccentric, a motor for rotating the eccentric, and an associated angularly tilted battery which powers the motor. A receptacle integrally associated with the neck of the housing is adapted to removably receive a standard blade cartridge for shaving. The razor exhibits a characteristic resonant frequency, and its center of mass lies apart from its central axis, so that the razor characteristically displays a dynamic couple in operation. The motor rotates within a speed range of between 1.414 and two times the natural resonant frequency of the razor so as effectuate as comfortable a shave as possible. Within this range razor shaving characteristics are substantially unaffected by the mode or manner in which the unit is held.

Abstract: An adjustable trailer hitch which includes a frame or housing capable of being removably attached to the bumper or frame of a truck, car, or other vehicle, and a rotatable, extensible, hinged arm adapted to pivot on, extend from, and retract into the housing. The arm is formed of an inner arm and an outer arm, the former of which is pivotally pinned at one end of the housing, and is fitted with a hinge which permits the inner and outer arm to selectively fold and retract into and extend from the housing. The outer arm is fitted with a ball coupling adapted to mate with a ball receptacle mounted on the tongue or other frame member of a trailer to be towed, and can be equipped with an optional shock absorber.

Abstract: An adjustable trailer hitch which includes a frame capable of being removably attached to the bumper or frame of a truck, car, or other vehicle, and a rotatable, extensible, hinged arm adapted to pivot on, extend from, and retract into the frame. The arm is pivotally pinned at one end of the frame and is fitted with a hinge in the approximate center, which hinge permits the arm to selectively retract into and extend from the frame, and to describe an acute angle when fully extended. The arm is fitted with a ball coupling adapted to mate with a ball receptacle mounted on the tongue or other frame member of a trailer to be towed.
