Abstract: An axle assembly has a longitudinal pivotal connection to a vehicle frame enabling it to rock about a longitudinal axis extending generally longitudinally of the direction of movement of the vehicle. One of the fore-and-aft ends of the axle assembly is hinged to the frame by a universal joint connection consisting of a ball and socket enabling completely unrestricted tilting, swinging and rocking movement of the axle assembly in all directions relative to the frame. At the opposite end, the axle assembly is freely tiltable up and down about a connection to the frame enabling free vertical movement of the tiltable end of the axle assembly while restraining horizontal movement. Springs support the vehicle frame at opposite sides of the axle assembly.

Abstract: This invention pertains to an improvement in box joint tools and particularly for reducing play resulting from wear of the members forming the box joint. The box joint is formed in the usual manner. This improved joint is used when or where wear develops or may be utilized with new tools at the time of assembly.

A counterbore is also formed in the second outer member portion and extends to about one thirty second of an inch from a central jaw tongue portion. This counterbore provides a flexure portion with a smaller bore axially coincidental with the axis of the central portion. A pivot pin bushing has a threaded bore and is sized to be a press fit in the formed counterbore and enlarged bore of the first outer member. This bushing is mounted in the first outer member and the shank portion extends into the tongue portion of the central jaw.

Abstract: An improved spring shackle assembly is utilized in an improved vehicle suspension system and includes a pair of socket assemblies which connect an end portion of a leaf spring with a mounting bracket. Each of the socket assemblies includes a rigid metal housing having an inner surface which defines a socket chamber in which a bearing liner is disposed. Each of the bearing liners encloses a spherical end portion of a ball stud. Each ball stud has a generally cylindrical shank which extends into an opening formed in an end portion of the spring. In order to tend to minimize the sideward load applied to the mounting bracket, the bearing liners have spherical surfaces which cooperate with the spherical head ends of the ball studs so that offsetting axial or sidewise forces are applied to the bearing liners by the ball studs. The socket assembly has a unitary construction to facilitate assembly and to minimize the chance for dirt and other foreign materials to enter the socket chamber.
