Abstract: A light truck support lift which is positioned between the existing leaf spring eyelet and the truck body which incorporates fastener adjustable members for varying the height of the lift.

Abstract: A vehicle stability control system is provided, which includes a movable tongue member and a ratchet mechanism. The movable tongue member is adapted to move between a first tongue position and a second tongue position. The ratchet mechanism is adapted to be mechanically coupled to a movable unsprung mass portion and to a sprung mass portion of a vehicle when the vehicle stability control system is operably installed on the vehicle. The ratchet mechanism comprising a ratchet tooth, such that the ratchet mechanism is adapted to restrict a movement of the unsprung mass portion away from the sprung mass portion when the tongue member is moved toward the second tongue position and into the ratchet tooth, and wherein the tongue member does not restrict the movement of the unsprung mass portion relative to the sprung mass portion when the tongue member is in the first tongue position.

Abstract: An automotive suspension is provided having a leaf spring coupled to a chassis of a vehicle and having a spring eye having a serrated inner surface. The system further has a spring pin having a serrated outer surface coupled to the serrated inner surface of the spring eye, and a fixing bracket limiting rotation of the spring pin relative to the vehicle chassis.

Abstract: An apparatus for mounting to a truck suspension system which provides reinforcement to standard leaf spring suspensions in a manner that is adjustable and flexible. It provides improved weight distribution while allowing for additional vertical travel of the suspension system during periods of extreme shock loading. The apparatus mounts to the vehicle frame at a location behind the rear axle between the rear axle and rear attachment point of the leaf spring. The apparatus is both vertically and horizontally adjustable and provides an adjustable amount of reinforcement, thus allowing the operator the match the amount of reinforcement to the load. The apparatus can be fully disengaged after installation and selectively used thereafter without requiring removal and subsequent reinstallation. In the disengaged position, the apparatus has no effect on the suspension system of the host vehicle.

Abstract: Selectively engagable auxiliary leaf springs (38 or 138) for vertically supporting a vehicle chassis (32) on an axle assembly (22 or 102) in parallel with main suspension springs (34 or 114). In three of the disclosed embodiments, both ends (38b,38a) of the auxiliary springs (38) are pivotally attached. In two other embodiments, one end (138a) of the auxiliary leaf springs (142) is pivotally attached and the other end (138b) is rigidly affixed in cantilever fashion. Actuators (56, 139 or 159) are employed to selectively enable or increase load supporting of the auxiliary leaf springs.

Abstract: Selectively engagable auxiliary leaf springs (38) for vertically supporting a vehicle chassis (32) on an axle assembly (22) in parallel with main suspension springs (34). Forward and rear ends (38b,38a) of the auxiliary leaf springs are pivotally attached to the vehicle chassis and the axle assembly, and pivotal movement of the forward ends (38b) is inhibited or prevented by engagement of actuator assemblies (56 or 100 or 170) to engage the axuiliary leaf springs. A control system automatically engages the actuator assemblies in response to load added to the vehicle and/or vehicle steering movement and/or rapid vehicle acceleration.

Abstract: Suspension adjustment for a suspension for a vehicle having a chassis frame and at least one pair of opposed transport wheels on opposite sides of the fore-and-aft axis of the vehicle, an axle extending between the wheels of each pair, the suspension including a pair of spring hangers attached to each opposite side of the chassis frame, and a leaf spring assembly on each side of the chassis frame interconnecting each pair of spring hangers with opposite ends of the axle in resilient load transfer relationship, each leaf spring assembly having a leaf spring with a spring eye at one end and a spring pin extending through the spring eye and through an aperture in an aperture providing formation rigidly secured to the one of the spring hangers to which the end of the leaf with the spring eye is interconnected, and mechanism for adjusting the fore-and-aft position of at least one end of an axle, the axle end adjusting mechanism comprising a first fastener adjustably fastening a spring hanger associated with an adj

Abstract: A vehicle spring suspension system comprising a primary spring and a secondary spring attached to the primary spring for aiding the primary spring to restore vehicle height and to carry increasing loads placed on or in the vehicle. The secondary spring is connected at one end by an assembly which can have serveral different arrangments for varying the load supporting function of the secondary spring on the primary spring, depending on the need for more or less load carrying cooperation between the primary and secondary springs.

Abstract: A tandem axle suspension wherein alignment of one axle relative to the other may be adjusted. The suspension includes a pair of spring hangers attached to each side of the chassis frame and a leaf spring assembly interconnecting each pair of spring hangers. Each leaf spring assembly includes a leaf with a spring eye at one end and a spring pin extending through the spring eye and through a transverse aperture in an aperture-providing insert rotatably mounted in the spring hanger to which the end of the leaf spring with the spring eye is interconnected. The spring hanger in which the insert is mounted has an upper portion by which it is attached to the vehicle chassis frame and depending portion having a transverse opening in which the insert is rotatably mounted. The depending portion is transversely bifurcated by a slot extending upwrdly into the transverse opening.

Abstract: An actuator for a vibratory material feeder comprises a base, a tray support, at least one spring for mechanically coupling the base and tray support, and a spring mount for mounting the spring to an actuator mounting surface on one of the base and tray support. The spring mount comprises first and second bearings each having a spring-abutting surface for supporting the spring therebetween, an arcuate surface and at least one hole therethrough; first and second bearing blocks each having an arcuate surface for mating with the arcuate surface of a corresponding one of the first and second bearings, and at least one hole therethrough. One of the bearing blocks abuts the actuator mounting surface. The spring mount further comprises at least one fastener having a shaft extending through the at least one hole of each of the first and second bearings and bearing blocks and a corresponding at least one hole in the spring.
