An adjustable axle-frame connector for mounting an axle to the frame of a vehicle. The adjustable axle-frame connector includes an axle mounting plate , an axle hold down bracket , and a U-bolt. The axle mounting plate with a first end for positioning on one side of the vehicle frame and a second end having a mounting slot formed therein. The first end is configured to engage the frame when the axle mounting plate is positioned between the frame and the axle , the axle extending transversely to the longitudinal axis of the frame. The second end has positioning tabs that are configured to straddle the axle when the axle mounting plate is positioned between the frame and the axle. The axle hold down bracket has a proximal end and a distal end, the distal end including a locator flange configured to engage the mounting slot of the axle mounting plate when the proximal end is placed in abutment with the frame of the vehicle. Lastly, the U-bolt urges the axle hold down bracket against the frame of the vehicle, thereby securing the axle to the vehicle as well.

The trailer hitch has a pair of tubular housings and , a coil compression spring in each housing, and a cable or. Each cable is telescopically slidable with respect to its housing, through its spring , and its proximal end is connected to the inner end of the spring by the cable/spring connector. When the hooks at the distal ends of the cables or are disconnected from the towing vehicle, the springs urge the cables into the housings.

A pivotal hitch assembly ( ) includes a housing ( ) that is pivotally coupled to mounting plates ( ) and ( ) that are rigidly attached to a draw bar ( ) of a trailer. The housing includes a pair of connector tubes ( ) that receive pins ( ), ( ) that couple the housing ( ) to the mounting plates ( ), ( ). The housing ( ) is manufactured from a single blank of material. The connector tubes ( ) are formed by bending or rolling a portion of the blank into a generally tubular shape. Bending or folding of the blank forms the housing such that the housing is generally U-shaped.

The trailer hitch () includes a guide bar () threaded about the stem () of the hitch ball (). An alignment plate () that is rigidly mounted to the lower wall of the trailer tongue () has converging guide surfaces ( and ) that receive the guide bar (), causing the guide bar and the crotch of the converging surfaces to become aligned as the guide bar engages the alignment plate. This aligns the ball receiving socket () of the coupler () with the hitch ball ().

A longitudinal stabilizing system for a premanufactured building having support joists extending along the length of the underside of the building and being supported above the ground by upright piers. The system comprises at least one foundation plate, a joist connector, a plate connector, and a rectilinear strut. The foundation plate is placed between the pier and the ground. The joist connector attaches to the joist of the building. Plate clamps may be used in conjunction with the joist connector to grasp the joist. The plate connector attaches to the foundation plate. The strut is attached to the joist connector at one end and the plate connector at the other end such that the strut slopes downward from the joist towards the ground. In high winds, the weight of the building and the weight of the pier resting on the foundation plate retard lateral movement of the foundation plate and the end of the strut attached to the plate connector, while the end of the strut attached to the joist connector resists movement of the joist along its length.

A pair of bunk board guide-on post assemblies are mounted on opposite sides of the frame of a boat trailer just at the aft ends of the bunk boards of the trailer. The guide-on post assemblies each include a rectilinear upwardly extending support bar that defines a longitudinal slot , and a buoyant guide-on post is telescopically mounted downwardly about the support bar and defines a laterally extending connector opening that registers with the longitudinal slot. A connector pin extends through the laterally extending connector opening of the guide-on post and through the longitudinal slot of the upwardly extending support bar so that the buoyancy of the guide-on posts telescopes upwardly in response to partial immersion of the bunk boards of the boat trailer, providing a visual indication of the location of the submerged ends of the bunk boards.

The support system for a premanufactured building includes a foundation platform () having cleat walls (-) that penetrate the ground. A support stand () and its vertical support shaft () function as a pier to support the joist () of the building. A diagonal stabilizing strut () is connected at its upper end to the same or to an adjacent joist, and at its lower end to the support stand, so that compression forces applied by the joist to the strut () move from one side of the vertical load axis () to the other side of the axis and engage the foundation platform, so that the ground adjacent the cleats (-) resists movement of the joist.

An axle assembly includes a spindle () that extends through a mounting collar () into the open end of the axle. A cam key () moves through a key hole () in the axle and registers with the cam slot () of the spindle. The cam surface () of the cam key () is reversible with the cam surface () engaging either the bearing surface () or the bearing surface () of the spindle, to urge the spindle into or out of the axle.
