Abstract
Abstract A transporting device for lifting and relocating material from one position to another. In one embodiment, the transporting device comprises a stationary central support pedestal and a rotatable turret situated at the top of the pedestal. The turret has at least a pair of arms which extend radially outwardly from the pedestal. Each arm has an adjustable lifting and stacking mechanism for gripping and transporting of material as the turret is rotated. In another embodiment, the transporting device comprises a rotatable central support turret situated on a stationary pedestal. A pair of arms extend radially outwardly from the turret. Each arm may be raised and lowered independently of the other and includes a mechanism for gripping material as the turret is rotated. In either embodiment, the turret is driven by a motor situated in the stationary pedestal.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
238 words
A transportion device for relocating large, heavy material such as coils of steel from one position to a second position, said transporting device comprising; a. a stationary central support pedestal, b. a rotatable turret situated at the top of said pedestal, said turret including i. a central support shaft, ii. at least two arms each of which extends radially outwardly from said shaft and which is rotatably fixed relative to said shaft while permitting vertical movement relative thereto, iii. a material support for each arm, means to raise and lower each said arm to raise and lower said material support, and means to enlarge and contract said material support to accommodate material of varying horizontal dimensions, said material support and said arm being connected directly to said support shaft, iv. said material support comprising a guide extending substantially the length of said arm and a pair of carriages located on said guide, each carriage being laterally moveable along said guide from an end thereof toward the center thereof in a direction opposite to the other carriage to enlarge or contract the separation between the carriages, said carriages including rests for holding material to be relocated and abutting opposite sides of said material as it is relocated, c. bearing means between said pedestal and said turret to facilitate rotation of said turret, and d. driving means situated in said pedestal and attached to said turret to rotate said turret.
Claim 2
Dependent Claim
238 words
A transportion device for relocating large, heavy material such as coils of steel from one position to a second position, said transporting device comprising; a. a stationary central support pedestal, b. a rotatable turret situated at the top of said pedestal, said turret including i. a central support shaft, ii. at least two arms each of which extends radially outwardly from said shaft and which is rotatably fixed relative to said shaft while permitting vertical movement relative thereto, iii. a material support for each arm, means to raise and lower each said arm to raise and lower said material support, and means to enlarge and contract said material support to accommodate material of varying horizontal dimensions, said material support and said arm being connected directly to said support shaft, iv. said material support comprising a guide extending substantially the length of said arm and a pair of carriages located on said guide, each carriage being laterally moveable along said guide from an end thereof toward the center thereof in a direction opposite to the other carriage to enlarge or contract the separation between the carriages, said carriages including rests for holding material to be relocated and abutting opposite sides of said material as it is relocated, c. bearing means between said pedestal and said turret to facilitate rotation of said turret, and d. driving means situated in said pedestal and attached to said turret to rotate said turret.
Claim 3
Dependent Claim
55 words
A transporting device according to claim 1 including a second pair of carriages located beneath said arm and each second carriage being movable in a direction opposite to the other second carriage, said second pair of carriages including rests for holding material to be relocated and being situated transverse to said first pair of carriages.
Claim 4
Dependent Claim
46 words
A transporting device according to claim 2 in which said means to enlarge and contract comprises a. a motor mounted on said arm and means drivingly attaching said motor to said first pair of carriages, and b. actuating means attached to said second pair of carriages.
Claim 5
Dependent Claim
64 words
A transporting device according to claim 3 in which said actuating means comprises a cylinder attached to said arm and one of said second pair of carriages and means interconnecting said second pair of carriages such that extension of said cylinder increases the spacing between said second pair of carriages and contraction of said cylinder decreases the spacing between said second pair of carriages.
Claim 6
Dependent Claim
45 words
A transporting device according to claim 1 in which said arms are mounted for raising and lowering to raise and lower said material support, and in which said means to raise and lower comprises a double-acting cylinder connected between each said arm and said turret.
