摘要： The lift unit for a weight distributing trailer hitch includes a fixed mounting bracket secured to the trailer tongue and a chain lift bracket that pivots on the mounting bracket to raise and lower a chain for flexing and unflexing a spring bar that distributes weight between the towing vehicle and the trailer with the spring bar in the flexed position. A locking pawl rotatably connected to the lift bracket has a lower arm portion for engagement with a detent in the fixed mounting bracket to releasably latch the lift bracket in a raised position. The locking pawl also includes an upper arm projection. The locking pawl is connected to the lift bracket with the pawl upper arm projection positioned adjacent a tool engagement finger on the lift bracket that is slidably engaged by a tool such as a pipe to aid in raising and lowering the chain lift bracket. Upon engagement of the tool with the tool engagement finger, the tool also engages the upper arm projection of the pawl to rotate the lower arm portion away from engagement with the detent in the mounting bracket and unlatch the lift bracket to lower the chain and unflex the spring bar.

摘要： A fully integrated, three-stage automatic weight distributing hitching system for a trailer and towing vehicle which utilizes a funnel-shaped receiver system (100), a head assembly (D) with elongated shank (160), spring bars (C) and chains (B), and a motorized electromechanical screw-driven piston device (382). The receiver, mounted on the Pear of the towing vehicle, is equipped with spring loaded dogs (140) which drop into machined recesses (240) of the shank when shank is inserted into the receiver, locking the shank in place and creating a secure coupling of the trailer and the towing vehicle. Solenoids (120) are affixed to the outside of the receiver and, when activated, will retract the spring-loaded dogs from the shank, and allow for uncoupling. The forward end of the receiver is fitted with a male portion of an electrical plug (180). The pivotable head assembly with ball (E) and shank extends from the trailer tongue (A). A tunnel (170) has been machined out along the length of the shank to house a cord (280) and a female portion of an electrical plug (220) which mates with the male plug in the receiver when inserted, and provides instant automatic connection of the electrical system between the trailer and the towing vehicle. The piston device is transversely mounted on the trailer tongue. Triangular cams (366) affixed to the ends of the piston device, cam support brackets (364) mounting brackets (350), and draw chains (B) produce tension and load-transferring capabilities of the spring bars when cams are rotated upward. These cams, when rotated downward, release the tension on the bars.

摘要： A weight distributing hitch for towing a trailer behind a vehicle includes a hitch bar for mounting to the vehicle and a ball mount head for mounting on the hitch bar at a selected tilt angle. A pair of spring bars are mounted to the ball mount head. These spring bars distribute the weight of the trailer relative to the vehicle. Each spring bar is substantially L-shaped and includes a turned groove at a proximal end received in a cooperating aperture in the ball mount head. A retainer of spring steel engages in the grooves to hold the spring bars in position. The relative tilt angle of the ball mount head is adjusted by means of an eccentric angle adjusting element in the form of a washer. This washer is fixed to one of the ball mount head or hitch bar and includes a cam surface for engaging the other of the two elements.

摘要： A jack carried by the draft tongue or A-frame of a trailer supports the front of the trailer during the coupling thereof to the hitch member of a towing vehicle and the jack is also utilized to tension the load transfer members which equalize the load on the wheels of the towing vehicle. Following the coupling and tensioning operations, a retractable engaging member on the jack is connected with a rigid load bearing member on a solid portion of the trailer A-frame which relieves the jack of heavy forces generated by or transmitted through the load transferring members during towing. Safety, convenience, and stability during trailer transport are enhanced by the invention.

摘要： In a spring bar trailer hitch assembly having spring bars each of which are connected at one end to the tractive vehicle to extend on one side of the trailer and the opposite distal end connected to the trailer so as to be free to move longitudinally relative to the trailer, the improvement comprising the connection of each of the spring bars in planes horizontally offset from the plane in which the hitch ball is located so that upon pivotal movement of the tractive vehicle and trailer relative to each other, as in fishtailing, will meet with significant initial resistance by both spring bars, but as the trailer moves further from the centerline of the tow car as in rounding a curve, the longitudinal movement of one of the spring bars relative to the trailer will be greater than such movement of the other spring bar thereby effecting a greater force on the side of the trailer on the outside of the curve than the force exerted on the side of the trailer located on the inside of the turn.

摘要： A device for preventing trailers hitched to passenger automobiles or tractors from swaying under the influence of lateral forces commonly encountered during relatively high speed straight line travel on highways. The device comprises a flat plate having a groove that faces and is engaged by a detent. The plate and the detent are mounted to the towing vehicle and the trailer and they are biased towards each other so that a torque of a predetermined magnitude is necessary to disengage the detent and the groove and permit sideway swaying, or relative angular movement of the trailer. After the detent is disengaged the necessary force to cause additional angular movements is reduced. The anti-sway device can be mounted to and used with conventional, already installed trailer hitches.
