Abstract
Abstract A utility trailer especially suited for transporting an automobile having a vehicle carriage that is reciprocally moveable to longitudinally and tiltable relative to the trailer frame to provide a shallow ramp for loading and unloading the vehicle. The trailer includes a self contained gasoline powered engine for driving a hydraulic fluid actuated system for controlling the position of the moveable carriage and a winch. The trailer includes a stop bar to prevent movement of the trailer during loading and unloading. The carriage is a rigid flat platform connected to an auxiliary frame that is pivotally connected to the main trailer frame. The carriage can be moved parallel to the auxiliary frame by the hydraulic actuator.

Total Claims: 6
Claim 1
Independent Claim
354 words
A utility trailer capable of being towed by a conventional automobile or small truck for transporting an automobile comprising: a rigid primary supporting frame having a front end and a rearward end, said primary frame being substantially rectangular and including a pair of parallel, longitudinal side members, and a pair of parallel, laterally disposed end members connected to said longitudinal side members, said primary frame having attached there to first and second forward members angularly joined together at one end forming an apex and connected to the front end of the primary frame at their opposite ends; at least one axle attached to said primary frame; a pair of wheels rotatably connected to said axle; trailer hitch connected to the apex of said first and second forward members connected to said front end of said primary frame for coupling said trailer to said conventional automobile or truck; a rigid, substantially rectangular auxiliary frame having a front end and a rearward end and including a pair of parallel, longitudinally disposed side members, said auxiliary frame pivotally attached at its rearward end to said primary frame, said auxiliary frame longitudinal side members being supported on top of said primary frame side members whenever said auxiliary frame is parallel to said primary frame; pivotal brake means connected at a rearward terminal end of the primary frame for engaging the ground to prevent movement of the trailer during loading or unloading; a rigid, flat carrier coupled to said auxiliary frame and moveable in a longitudinal direction relative to said auxiliary frame; means connected to said primary frame and at a forward terminal end of said auxiliary frame for pivotally moving said auxiliary frame; and means for moving said carrier longitudinally relative to said auxiliary frame; said carrier being sized in length relative to said auxiliary frame and said primary frame that one end of the carrier engages the ground at a shallow angle suitable for loading or unloading a conventional automobile whenever the auxiliary frame is raised to its upper most pivotal position and the carrier is moved to its rear most position relative to the auxiliary frame.
