Abstract: An articulating ball joint for connecting a pair of driven members to a driving member such as a crank pin. In one embodiment, a single ball is held in a first, or inner, socket defined by a coupling member having a convex outer surface, and the first socket is held within a second, outer, socket defined in a second coupling member also having a convex outer surface, which is, in turn, engaged by a retainer.

Abstract: A wiper drive system including a wiper drive mechanism driving a pair of wiper drive arms to sweep a wiper blade across a surface. The wiper drive mechanism has a motor driving a rack engaged with a sector gear that is supported by pivot bearings. Each wiper drive arm is driven by a sector gear.

Abstract: A wiper drive system and method for installation of a wiper pivot shaft through a structure whose opposite faces may not be parallel. A mounting body supports a bearing support tube and has a concave front side. A mounting ring surrounds the bearing support tube and has a convex rear side that rests adjustably against the concave front side of the mounting body.

Abstract: A linear actuator for a platform having a frame with an open end and a platform moveable within the frame, said platform driven by a motor powered axle mounted traversely to the platform. The platform is driven by a drive system powered by the motor driven axle and generally having a pair of fixed pitch independent devices, such as chains, each chain mounted at each of its ends to the frame and aligned with the platform's axis of travel, a double drive sprocket adjacent an end of the axle, a pair of double idler pulleys aligned substantially with a chain, a pair of single idler pulleys aligned substantially with the other chain. Each chain is routed through the double drive sprocket and one chain routes through the double idler pulley, while the other chain routes trough the both the double idler pulleys and the pair of single idler pulleys.

Abstract: A windshield wiper drive train adapted for long life. The drive train includes motor assembly that supports and drives a drive shaft. A circular drive plate is attached eccentrically to the drive shaft to rotate through an eccentric orbit about the drive shaft as the drive shaft rotates. A connecting member having a body portion defining a round opening that is slidingly fitted about said circular drive plate and an arm portion extending outwardly from the body portion undergoes reciprocating motion in response to rotation of said circular drive plate. A rocker assembly having a rockshaft and a rocker arm attached to the rockshaft is connected by pivot joint to the arm portion of the connecting member. In operation, the rocker assembly is rocked by the reciprocating motion of the arm portion when the drive shaft rotates. The rockshaft is adapted to engage a further attachment such as a windshield wiper.
