Abstract: One half of a Pot-type universal joint consists of four spherical rollers rotatably mounted, but axially fixed on four mutually perpendicular radial trunnions. Each roller rolls in a grooved member connected to the other joint half. The four grooved members are free to move relative to each other and to their supporting joint half, but only in a way that satifies the kinematic requirements set forth in the specification, while providing a torsionally rigid connection between the two joint halves. The transmission of torque is homokinetic. The joint is adaptable for either axially fixed or axially displaceable requirements.

Abstract: A Pot-type universal joint transmits torque from one shaft to another using four rollers mounted on four trunnions. The trunnions maintain their mutual perpendicularity under all operating conditions. They are free to move relatively to each other and to the shaft to which they are joined but in a way that satisfies the kinematic requirements set forth in the specification, while providing a torsionally rigid connection between the shafts. The transmission of torque is homokinetic. The joint is adaptable for either axially fixed or axially displaceable requirements.

Abstract: A universal joint has two shafts, axially restrained, but pivotable from a common point. One shaft end is in the form of a thick-walled hollow sphere. Two axially extending grooves are cut into the wall facing each other in a circumferentially opposed relationship to form a first set. The other shaft end is in the form of a spherical bowl having a central ball. The inside surface of the bowl and the surface of the ball define an annular spherical cavity into which the hollow sphere nests. Two axially extending grooves are cut, one in each surface, in a radially opposed relationship to form a second set. Each set of grooves positively determines the line path that the center of an enclosed ball will travel. In the assembled joint, the line paths are in mirror image relationship and always intersect in the homokinetic plane. The ball, being enclosed by each set is forced to occupy the intersection. The number of balls used can be any number, odd or even.

Abstract: A wire stripping machine for stripping the insulation from the end of a stranded-core, insulated wire and twisting the conductor strands includes upper and lower stripping heads mounted on a support for movement between an open position and a closed, operative position. Each stripping head includes an elongated stripping element assembled from a stripping bar having a serrated wire contacting surface and an insulation cutting knife that extends along the length of the stripping bar and that presents a cutting edge positioned a selected distance above the wire contacting surface. In operation, the entire machine is advanced from an initial position over the end of an insulated wire and the upper and lower stripping heads are moved from their open position to their operative position.

Abstract: A wire stripping machine for stripping the insulation from the ends of a plurality of stranded-core insulated wires and twisting the exposed conductor strands includes upper and lower stripping heads mounted on a support for movement between an open position and a closed, operative position. Each stripping head includes wire separating discs that separate the wires to-be-stripped so that they lie laterally adjacent one another and a stripping element that simultaneously strips the insulation from the ends of the wires and twists the conductor strands. Each stripping element includes an elongated stripping bar having a serrated wire contacting surface and an insulation cutting knife that extends along the length of the stripping bar and presents a cutting edge positioned above the wire contacting surface.
