Abstract: A boat trailer frame is described including an adjustable pair of elongated frame members extending from a tongue section to a wheel supported carriage. Bunks are mounted directly to the frame members. Forward ends of the frame members are pivotably mounted to the tongue and selectively clamped to the wheel carriage. Lateral adjustment of the distance between the frame members and bunks is provided to accommodate boat hulls of varying configurations. Such lateral adjustment is accomplished simply by pivoting the frame members together or apart about the forward pivots at the tongue. Clamps are included for selectively securing the frame members to the carriage assembly and tongue once a selected space between the bunks is achieved. Other clamps are used to facilitate longitudinal adjustment of the wheel carriage position along the frame members to adjust "tongue weight".

The hopper is provided with backing plates which facilitate the engagement and disengagement of the hopper from the trailer.

Abstract: A silo mover apparatus comprising a main frame that is movable across the ground on a plurality of support wheels, and which has a subframe pivotallymounted thereon adjacent one end. The subframe can be raised about the pivot to a substantially vertical position through the use of hydraulic cylinders, stabilized in position adjacent to a silo to be moved, clamped to the silo by straps, after the silo has been suitably reinforced, and then the silo can be lifted and tilted downwardly with the subframe to rest on the main frame for transport to a new location. At the new location the silo is then raised by raising the subframe about its pivot, to place the silo onto the desired platform, after which the members that clamp the silo and subframe together are removed.

Abstract: A truck and trailer assembly adapted to travel over the road in a traveling mode, where the trailer is spaced a substantial distance from the truck, and also adapted to operate in a maneuvering mode where the trailer is more closely coupled to the truck, and the front steerable wheels of the trailer are raised out of ground engagement. In the various embodiments, this is accomplished by rotating the reach of the trailer relative to the trailer, so as to lift the forward wheels of the trailer from the ground. The reach is conveniently shortened by providing the reach as three telescoping members.

Abstract: A loader and transporter for large loads such as cotton modules has a wheel-mounted main frame, which may be self-propelled or of tractor-drawn trailer type, a deck, incorporating a reversible longitudinal conveyor, being connected by a transverse pivotal connection to the main frame. Lifting means are provided for raising and lowering this pivotal connection and the deck and tilting means are provided for tilting the deck so that, when the deck is lowered, it can be tilted from a substantially horizontal low-load travelling position to a position for loading from ground level, and when the deck is raised, it can be tilted from a substantially horizontal high-load travelling position to a position for unloading onto a semi-trailer, for example.

Abstract: A self-leveling boat trailer adapted to be towed behind a vehicle. In one embodiment, the trailer includes a pivotally mounted tongue assembly and a wheeled undercarriage. A flotation system at the stern end of the trailer causes the stern of the trailer to float upon entry into the water. A control linkage is utilized to pivot the tongue assembly in response to the flotation of the trailer stern, lowering the bow end of the trailer, thereby maintaining the trailer in a level position. In a second embodiment, the entire support platform pivots while the tongue assembly and wheeled undercarriage are coupled to a single rigid member. In either embodiment, boat launch and recovery are improved by maintaining the trailer in a level position despite the incline of a typical launching ramp.

Abstract: A wheeled trailer has a frame adapted to be coupled by a drawbar to a towing vehicle. The drawbar has a rear end capable of attachment at any one of a number of vertically spaced points to an anchor member and has an intermediate portion removably retained in an open bottom socket within which is a fulcrum. Vertical adjustment of the rear end of the drawbar effects vertical adjustment of its forward end in a manner to compensate for varying height trailer hitches on different vehicles and enable the trailer bed to occupy a substantially horizontal position. The trailer frame is capable of rocking movement about the axes of its wheels to a position in which the rear end of the trailer bears against the ground.

Abstract: A combination trailer/launcher apparatus which includes an inner adjustable and movable frame for launching and loading a boat. The apparatus ensures that the boat will be oriented in a substantially horizontal fashion so that the boat is delivered flat into the water into which it is being launched. The boat is also constrained to travel in a horizontal fashion when being transported from a location to another location. Two separate and distinct inclines control the motion of the inner movable frame relative to the main frame of the trailer.

Abstract: The trailer has a main frame of generally U shape having stub axles on which ground-engaging wheels are journalled. A structurally rigid boat supporting frame is suspended from the main frame by a cable and pulley arrangement which enables the boat supporting frame to be raised and lowered horizontally and to be tilted lengthwise to a relatively steep angle relative to the main frame. The desired degree of tilt is facilitated by the fact that the front end of the boat supporting frame can be pivotally connected to the main frame at various heights.

Abstract: A trailer for transporting farm implements and the like is disclosed. The trailer bed is longitudinally shiftable from a horizontal load transporting position mounted on a wheeled chassis to a horizontal loading position on the ground adjacent the chassis by means of a slide assembly pivotable relative to the wheel axle. After loading, the trailer bed is urged up the inclined slide assembly by backing the pulling vehicle, such as a pickup truck. Shifting of the trailer bed on the slide assembly is facilitated by cooperating rollers mounted both on the trailer bed frame and on the slide assembly.

Abstract: A vehicle transport trailer, which is capable of carrying three to four vehicles and can be hauled by a pick-up truck. The trailer has two levels. The upper level has a rear end portion which is sloped towards the ground and is used as a ramp for loading and unloading. A hitch is attached to the front end of the upper level. A lower level is hinged to the main body of the trailer and is attached to the front end of the upper level by power activated telescoping members which are movable between a first position in which the trailer can be hauled at its hitch by a pick-up truck, and a second extended position in which the trailer is supported by the front end of the lower level and the rear end of the upper level, with the front end of the upper level and the hitch being pivoted upwardly to allow free access for loading and unloading of the lower level.

Abstract: A tiltable bed is provided with a set of toothed chains and a control system therefor so that the chains are moved along the length of the bed at a linear speed which corresponds to the linear speed of movement of the bed relative to the ground and independent of the rate of movement of ground engaging means directed to move that bed along the ground: thereby there is no strain put on a cotton module engaged and caused to traverse the length of such bed by those moving chains while being lifted or lowered during adverse traction conditions.

Abstract: An articulating coupling for connecting two wheeled vehicles includes a pivot connection and a tilt mechanism. The pivot connection is provided between the two vehicles so that they can turn relative to each other in the horizontal plane and be selectively turned relative to each other. The tilt mechanism includes a horizontal pivot connection between the two vehicles so that vertical movement of at least a portion of one vehicle adjacent to the horizontal pivot connection will move a portion of the other vehicle adjacent to the pivot connection in the same direction and cause the other vehicle to pivot about the axis of its wheels.

Abstract: A trailer adapted to carrying a plurality of vehicles, such as snowmobiles, includes a plurality of wheels and a pair of vehicle supporting trailer beds normally disposed in a use position in side-by-side relationship on a frame. Each one of the trailer beds is pivotally mounted on the frame at the rear edge thereof forwardly of the mid-point of the bed to enable it to tilt individually and independently backwardly until its rear edge contacts the ground for loading and unloading purposes and to enable the loaded bed to tilt back to its horizontal use position under the weight of the vehicle supported by it. Bumper devices are disposed on the frame for cushioning the movement of the bed under the weight of the vehicle, and latching devices hold the beds releasably in their horizontal position. Camming devices engage the beds as they move into their use positions for moving the latches to their release position, and spring biasing devices enable the latching devices to return to their holding positions.
