Abstract: A disclosed hitch receiver assembly includes receiver having a worm gear and a slide bushing, a worm shaft engaged to the worm gear for laterally moving the receiver, a slide bar extending through the slide bushing and fixed at each end to a static structure, a hitch received within the receiver and a receiver pin coupling the hitch to the receiver and the static structure.

Abstract: A drawbar for a trailer hitch receiver tube has a translation screw passing from the back end to the front end of the drawbar in a longitudinal unthreaded passage in the drawbar. A ramp nut is threaded onto the translation screw and is retained in a ramp nut chamber in the front end of the drawbar. A captive ball is retained in a captive ball retention chamber passing between the ramp nut chamber and the exterior of the drawbar. A ramp on the ramp nut pushes the ball to extend beyond the exterior of the drawbar when the translation screw is turned to pull the ramp nut backward in the ramp nut chamber. This eliminates all play between the drawbar and the receiver tube in which the drawbar is inserted. A spring between the ramp nut and the drawbar may urge the ramp nut forward.

Abstract: A shifting module for releasable securement on the lower two arms of a conventional three-point hitch of a tractor and for laterally shifting a pull-type implement mounted on the shifting module. The shifting module includes a lateral support having a pin on either end section for grasping and securement by the lower two arms of the three-point hitch. A traveler is mounted on the lateral support and a linear actuator operates to shift the traveler along the lateral support to any desired position along the lateral support. A hitch on the traveler is used for mounting of the pull-type implement so that the implement can be reliably and accurately positioned along a desired path.

Abstract: Provided is an adjustable trailer hitch assembly and method of use that permits one person to controllably move the hitch within a plane of defined boundaries. Trailer hitch assembly includes one or more longitudinally extending assemblies for mounting under a vehicle, a cross-bracket assembly attached substantially perpendicularly with telescoping assemblies, a receiver portion slidable in said cross-bracket assembly, and a ballmount fixed with said receiver portion with a pin. Telescoping assemblies and cross-bracket assembly include control mechanisms, which may include motors and worm gear drives, to move the receiver portion longitudinally and latitudinally, respectively, thereby moving the ballmount and hitch ball within a predefined plane. An integral safety latch system is also provided.

Abstract: An adjustable trailer hitch which provides an operator improved remote control of the lateral position of a trailer hitch, and simplifies the procedure of hooking a trailer to a tow vehicle. The trailer hitch comprises a hitch assembly (such as a ball receptacle) attached to a roller carriage which moves from side-to-side along a bumper-like housing. The roller carriage engages a positioning screw, and an electric motor mounted in a sealed end cap powers the positioning screw. Rotation of the screw translates into rightward or leftward lateral movement of the roller carriage and consequently of the ball receptacle assembly. Motion of the ball receptacle assembly is controlled via a wireless remote control unit. Such direct control over the precise lateral position of the trailer hitch enables the operator to accurately steer the trailer when traveling in reverse.

Abstract: An adjustable hitch assembly is mounted on a towing vehicle and is adapted to move the hitch transversely, horizontally and vertically with respect to the towing vehicle. A first traveler is provided in a horizontally disposed C-shaped channel and is selectively movable along the channel with a rotataly driven threaded rod. A vertical C-shaped channel is mounted to the first traveler. A second traveler is provided in the vertical channel and is selectively movable along the vertical channel with a threaded rod extending longitudinally in the vertical channel. A hitch is mounted to the vertical channel traveler and is adapted for connecting to a trailer.

Abstract: Disclosed herein is an adjustable tongue assembly for a trailer including an elongate substantially enclosed housing with a lengthwise slot disposed horizontally at the front of the trailer bed. A guide carriage is movably seated in the housing, and the guide carriage is attached to a bracket attached exteriorly of the housing through the lengthwise slot. The guide carriage is journalled to a positioning screw that is rotatably seated lengthwise inside the housing. The positioning screw is coupled to a motor which drives the guide carriage laterally along the internal chamber. A trailer tongue is attached to the external bracket. Selective actuation of the drive motor causes the positioning screw to rotate, thereby moving the roller guide carriage laterally left or right, and thus carrying the bracket and trailer tongue therewith.

Abstract: An improvement of a plow or a harrow of the type in which a plurality of saucer-like disks carried by a rotary shaft inclined at an angle with respect to the direction of travel of a tractor are forced to rotate, thereby plowing uncultivated farm land. The plurality of disks or disk gang is supported by a parallel linkage system and the angle of the disk gang with respect to the direction of travel of the tractor can be freely selected so that, in accordance with the skill of an operator and soil condition which will be encountered, either the horizontal travel or the inclined travel may be selected.

Abstract: A system for connecting, a towing, pushing, or hoisting self-propelled vehicle to a non-propelled vehicle utilizes two, three, four or five links connected to each vehicle by respective ball joints. The links converge so that the centers of the non-propelling vehicle's forces and motions can be located at places favorable to the steering, stability, and weight distribution of the two vehicles, usually at or near the center of gravity of the self-propelled vehicle. The locations of steering and carrying centers are determined by point-centers or two-or three-degree-of-freedom linear combinations of line-centers where lines extended from the links intersect in points or lines of intersection. The invention includes apparatus for varying the location of the virtual steering and support centers when the vehicles are at rest or in motion, by changing the separation of the hinge points or ball joints on either vehicle.

Abstract: A trailer hitch system (10) having longitudinal hitch ball movement whereby a trailer tow point can be laterally adjusted. The longitudinal hitch ball movement is facilitated by a screw shaft (20) housed in the trailer hitch system (10) and readily accessible from either side of the trailer hitch system (10). The trailer hitch system (10) may accommodate multiple hitch balls (22, 23) and allows any one of the hitch balls (22, 23) to be selectively centered on a bumper (82) of a towing vehicle. Hitch balls (22, 23) of diverse sizes may be interchanged while the trailer hitch system (10) is installed on the towing vehicle. The trailer hitch system (10) may be adapted to any type of towing vehicle. An adaptor (110) allows attachment of other types of hitches which are also laterally adjustable therewith.
