Abstract
Abstract An articulated flat bed trailer for transporting large, bulky objects such as ships propellers and the like. The flat bed of the trailer includes a hinged portion hydraulically rotatable from the horizontal position to an angle of approximately 55* 35* from the horizontal to minimize simultaneously horizontal and vertical overhang of the object. Means are provided to maintain the center of gravity of the rotated flat bed portion object combination within safe limits.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
133 words
Apparatus for transporting an object having one dimension substantially smaller than its other dimensions, which comprises: a main body member adapted to receive at least one pair of rotatable transporting wheels; a secondary body member pivotally mounted to said main body member; means, connected to said main body member, for rotating said secondary body member about an axis parallel to the principal longitudinal axis of said main body member between a position substantially co-planar with said main body member and a position substantially normal to the plane of said main body member; and means, connected to said secondary body member, for mounting said object to said secondary body member so that as said secondary body member is rotated by said rotating means, the horizontal and vertical overhang of said object is minimized simultaneously.
Claim 2
Dependent Claim
133 words
Apparatus for transporting an object having one dimension substantially smaller than its other dimensions, which comprises: a main body member adapted to receive at least one pair of rotatable transporting wheels; a secondary body member pivotally mounted to said main body member; means, connected to said main body member, for rotating said secondary body member about an axis parallel to the principal longitudinal axis of said main body member between a position substantially co-planar with said main body member and a position substantially normal to the plane of said main body member; and means, connected to said secondary body member, for mounting said object to said secondary body member so that as said secondary body member is rotated by said rotating means, the horizontal and vertical overhang of said object is minimized simultaneously.
Claim 3
Dependent Claim
93 words
Apparatus according to claim 1 wherein said mounting means is slidably connected to said secondary body member, and the apparatus further comprises: means, connected to said secondary body member, for altering the relative position of said mounting means with respect to said secondary body member so that, as said rotating means alters the angle between said main body member and said secondary body member to minimize said horizontal and vertical overhang, said mounting means is moved to maintain the center of gravity of said apparatus substantially centered over the principal longitudinal axis thereof.
Claim 4
Dependent Claim
25 words
The apparatus according to claim 2 wherein said rotating means comprises at least one cylinder means operable by a controlled supply of a pressurized fluid.
Claim 5
Dependent Claim
23 words
Apparatus according to claim 2 wherein said altering means comprises at least one cylinder means operable by a controlled supply of pressurized fluid.
Claim 6
Dependent Claim
22 words
Apparatus according to claim 3 wherein said main body member comprises the flat bed portion of an articulated flat bed tractor trailer.
