Abstract: An improved ball joint structure for clamping a rear view mirror head tightly yet turnably on a supporting ball member includes a ball seat member and a body clamping member fixed at the outer and inner sides of housing wall portions bordering an opening in which a mirror supporting ball is disposed, a ball clamping member mounted on the body clamping member and having a contoured portion to grip the inner side of the ball, and means adjustable from outside the wall for holding the ball clamping member under a desired tension against the ball. The body and ball clamping members have coacting formations that limit displacement of the ball clamping member in the direction away from the ball.

Abstract: A liquid dispensing pump of the motor-driven flexible vane impeller type suitable for use in an automobile windshield washer system includes a housing that defines a motor chamber having a motor supporting end wall. A closure wall is fixed to the end wall and an impeller chamber having a peripheral surface is defined between the walls. An impeller is rotatable in the impeller chamber by a motor supported in the motor chamber, which has a shaft that extends through an opening in the end housing wall. Inlet and outlet passages respectively conduct liquid to and from the impeller chamber. This pump further comprises the improvement that the impeller chamber is constituted by confronting recesses, formed in the closure and end walls, that are circumferentially bounded by portions of the walls that have confronting surfaces meeting at a tight interface. The interface bounds the peripheral impeller chamber surface.

Abstract: A windshield wiper blade unit including an elongate backing strip having a slotted central hollow to receive slidably the head and neck portions of an elastic wiper blade, and having along its sides laterally open channels to receive blade holder claws, is held detachably in place on such claws by a resilient clip formed with a base portion lying across an end of the backing strip, a footing portion extending forwardly from the base portion and fixed to a central portion of the strip, and elastically convergable resilient wing portions extending forwardly from ends of the base portion and each having a substantially flat leg extending therefrom inwardly and then forwardly, over and in face-to-face relation to an upper side flange of the strip, to a claw latching portion protruding outwardly from the leg.

Abstract: In a windshield wiper blade holder comprising pressure distributing claw yokes articulated to the ends of a primary yoke adapted to be coupled with a wiper arm, each claw yoke is a molded plastic body having between its arms an upwardly open coupling and bearing structure that is snappable onto mating structure on an end of the primary yoke and provides a highly durable pivotal connection yet can be produced in a simple two-part mold. As a further feature, the inner arm of each claw yoke is constituted by an upwardly open channel that receives a fitting, substantially rigid beam structure of the primary yoke and nests progressively farther with it, up to the arm end, as the wiper is moved over more steeply curved windshield surfaces, thus increasing the lateral stability of the blade holder; and the outer claw arm is formed oppositely as a downwardly open channel, enabling claw yokes having the required rigidity to be provided with molded wall sections of relatively little thickness and weight.

Abstract: An adapter for coupling a windshield wiper blade holder with a wiper arm of the type having a hooked end is provided as a unitary molded body of a resilient plastic material forming similarly shaped side panels held spaced apart and joined together by a front wall and a cross shaft which are so disposed relative to portions of the panels that the arm hook can be engaged onto the shaft when the body is turned away from a posture in which it can be coupled with the blade holder, and will be captured operably in the adapter when the body is turned back to that posture.

Abstract: A support device for easily mounting a rear view mirror onto a front wheel fender of a motor vehicle to enable viewing behind a hauled camper or other trailer comprises a pair of arms spaced apart laterally at their inner ends and adapted to protrude from the vehicle fender, a leg connected pivotably at its outer end with the outer ends of the arms, a mirror support means fixed at the junction of the leg and arm ends, and special coupling structures for interconnecting and converging intermediate portions of the arms and the leg so as to grip a fender tightly between footing members on their inner ends.

Abstract: A replaceable wiper blade unit to be received within the claws of a windshield wiper blade holder includes a longitudinally hollow backing strip slotted along its bottom for receiving an elastic wiper blade, and having along its opposite sides laterally open channels defined between upper and lower lateral flange, with an especially formed and attached resilient metal clip on an end of the backing strip for fastening it detachably to a set of claws. The clip includes a base portion to underlie an end portion of the strip, two resilient legs extending forwardly from the base portion, each beneath a lower flange, an upturned ridge portion protruding from a forward portion of each leg into a respective channel through an opening in the lower flange, and side structures turned upwardly from opposite side edges of the base portion to provide a finger crimped over and upon each lower flange and a claw abutting finger in each channel.
