Abstract: A fluid joint of the type including a generally rigid metallic tube having an annular bead spaced from the free end of the tube to define a pilot portion between the bead and the tube free end, a generally flexible hose sized to fit at a free end thereof over the pilot portion, and a metallic ferrule crimped at a first end thereof over the hose free end and adapted to be crimped at a second end thereof over the tube pilot portion. The joint further includes an elastomeric ring positioned in surrounding relation to the tube pilot portion between the bead and the second end of the ferrule so that, as the second end of the ferrule is crimped against the tube pilot portion, the elastomeric ring is trapped between the second end of the ferrule and the bead to preclude the entry of contaminants into the interface between the tube and the ferrule so as to discourage corrosive galvanic action between the dissimilar materials of the ferrule and the tube.

Abstract: A pin (18) is provided for attaching a connector or an adaptor (16) to a wiper blade (10). The pin (18) has a novel head (70) on one end portion which has spaced tangs or tabs (72) depending therefrom. The spaced tangs or tabs (72) nest in slots (44) provided on the connector or on the adaptor (16) to retain the pin (18) in a piggyback manner on the connector or adaptor (16) during shipment and storage. Securing the pin (18) on the connector or adaptor (16) prevents losing or misplacing the pin (18) until it is ready for use in attaching the connector or adaptor (16) to the blade (10).

Abstract: In a windshield wiper assembly (10), a connecting adaptor (14) converts a center mounted pin connection between a wiper arm (11) and a pressure-distributing yoke (13) to a side mounted pin connection. In assembled position, the connecting adaptor (14) is disposed over the cross rivet (28) within a center open space (20) defined by the yoke (13). The connecting adaptor (14) has deflectable claw elements (36) with tabs (53) which engage the side walls (16, 17) of the yoke (13) to fixedly maintain the connecting adaptor (14) in proper assembled position. A connecting pin (33) carried by the connecting adaptor (14) and extending laterally outward therefrom provides a side mounted pin connection for pivotally receiving the terminal end (75) of the wiper arm (11).

Abstract: In a pressure-distributing superstructure for a wiper blade having at least two parts connected together with one part having a pair of spaced laterally aligned claws extending inwardly toward each other and adapted to be positioned about the other part on either side thereof. A locking clip is positioned in abutting relationship with the undersurface of the other part to retain the claws on said one part in assembled relation with the other part. The locking clip is flexible and has a mounting portion with attaching means at the free ends of the legs thereof for interlocking engagement with the other part. The locking clip may be engaged or disengaged by deflection of the leg. The locking clip also has a latching portion with legs in which recesses are formed and through which recesses the respective claws extend. Each claw engages the undersurface of its respective leg so as to maintain a connection between the parts.
