Patent number: 5360226Abstract: The Grab and Center Boat Loading System is a centering guide system which helps one person load a boat on a boat trailer with no other person assisting. The system consists of two side mounted, spring loaded, rotating guides and one front mounted fixed standing guide which may be mounted on most boat trailers. Because each side mounted guide is designed to rotate forward and down if struck from the aft or stand and hold if struck from the side direction, this system helps a person safely load even large boats without any assistance. If, while being loaded, the boat rams one of the guides from the aft direction, the guide will rotate forward and down rather than damage the boat or itself. It will then begin to raise back up and begin to center the boat over the trailer. Once both side guides are standing with the boat confined between them, the boater then simply points the bow toward the front mounted guide and drives the boat slowly and safely to the front of the trailer.Type: GrantFiled: May 14, 1993Date of Patent: November 1, 1994Inventors: Ova L.

Patent number: 4453881Abstract: A roller assembly for a boat trailer is provided which does not call for careful alignment of the boat with respect to the trailer. The assembly is inclusive of a frame and, on the frame, a roller, a mounting member and a coupling member. The mounting and coupling members are such that a limited rocking movement of the assembly is permitted, this movement coming into play in response to an offset load bearing force.Type: GrantFiled: August 12, 1981Date of Patent: June 12, 1984Inventor: Keith Cowley

Patent number: 4448438Abstract: A boat trailer for loading, transporting and launching a boat includes a wheel-supported frame having a pair of longitudinally-extending frame rails. A transversely-extending aft support cradle is connected to the frame rails and is arranged to pivot relative to the rails in forward and rearward directions to facilitate loading and launching of a boat. The cradle is of a U-shaped configuration, having a pair of support arms which extend upwardly at opposite ends of a cross-beam. The support arms overlie side portions of the frame rails and are pivotally connected to the frame rails near upper surfaces thereof. The cradle carries at least one longitudinally extending rocker arm which supports hull engagement rollers. The pivotal connections between the support arms and the frame rails are located relatively high with respect to the locations of the hull engagement rollers.Type: GrantFiled: September 23, 1981Date of Patent: May 15, 1984Assignee: The Tee Nee Trailer CompanyInventor: Arnold R.

Patent number: 4416579Abstract: A cargo guide assembly includes a base which is mountable to the floor of a cargo hold in a transport vehicle such as an aircraft. A guide rail is pivotally attached to the base for swinging movement between a first position in which the guide rail contacts the side of a cargo container in the cargo hold, thereby restraining movement of the cargo and a second position in which the guide rail lies below the cargo floor, thereby permitting cargo to pass over it. A powered actuator is mounted on the base and is coupled to the guide rail by actuation linkage operable to move the guide rail from its first to its second position. Preferably, the assembly includes a latch for latching the guide rail in its second position and a biasing device associated with the base to bias the guide rail toward its first position.Type: GrantFiled: June 29, 1981Date of Patent: November 22, 1983Assignee: The Boeing CompanyInventor: John Alberti

Patent number: 4411349Abstract: A conveyor device useful also as a bulkhead in a storage compartment for trucks, railroad cars and cargo holds in airplanes, boats and the like. The conveyor device comprises a frame having adjustable bar means carried by the frame, to be pressed against the walls of the storage compartment to secure the frame as a bulkhead across the width of the storage compartment. Article conveyor track means are removably carried by the frame. Typically, in the bulkhead mode the track means serve as part of the bulkhead wall, while during loading or unloading the track means may be used to convey articles.Type: GrantFiled: July 6, 1981Date of Patent: October 25, 1983Assignee: Walgreen Co.Inventors: Thomas R. Stedman, Ronald A. Voyda

Patent number: 4371299Abstract: A transporter or trailer for endwise transport of combine headers and the like, consists of a standard four-wheel wagon running gear carrying an elongated generally rectangular frame providing support surfaces compatible with a variety of sizes and types of header. A pair of longitudinally spaced fixed pockets at the left-hand side of the adapter frame receives heel portions adjacent the rear of headers of the corn head or row-crop head type while a somewhat elevated, swingably adjusted, rail may be set to an appropriate contact and support forward portions of a particular header. In alternative embodiments, an auxiliary laterally adjustable rail may support a second front portion of a header, or additional support "cradles" may be attached along the left-hand side of the frame to accommodate headers with elongated transverse beam members such as grain platforms.Type: GrantFiled: July 24, 1980Date of Patent: February 1, 1983Assignee: Deere & CompanyInventors: Darryl F. Cain, Kevin L. Ehrecke

Patent number: 4329108Abstract: An adjustable length boat trailer has a rigid framework mounted on an axle supported by wheels. The framework has a rearward U-shaped portion and a pair of converging arm sections at its forward end. A T-shaped elongated tongue member is slideably and releasably secured to the framework. The tongue member has a forward elongated shaft portion having a hitch connection and rearward outwardly disposed crosspiece arms. The shaft portion is slideably and releasably secured between the converging arm sections while the crosspiece arms are adjustably and releasably secured to the U-shaped portion of the framework. Each of the crosspiece arms pivotally supports a roller assembly which is moveable along the length of the arm.Type: GrantFiled: June 15, 1979Date of Patent: May 11, 1982Inventor: Byron L. Godbersen
