Abstract:
1. A device for maneuvering cylinders, the device comprising first and second lifting members hingedly connected to one another, each lifting member including: a body substantially configured in a semicircle having opposite first and second free ends with a curved interior surface and an opposite exterior surface extending between the free ends and defining first and second free edges, a handle attached to a substantial mid-portion of the exterior surface of the body and oriented substantially perpendicular to the exterior surface, a first L-shaped hinge member located adjacent the first free end having a minor leg portion extending horizontally away from the exterior surface and a major leg portion extending vertically from the minor leg portion and horizontally past the first free edge of the body, and a second L-shaped hinge member located adjacent the second free end and having a minor leg portion extending horizontally away from the exterior surface and a major leg portion extending vertically from the minor leg portion and horizontally past the second free edge of the body so as to be in a facing relationship with the first hinge member, wherein each hinge member extends vertically away from its respective body at an angle of from about 55 to about 65 degrees; wherein the first and second lifting members are hingedly connected to one another by hingedly connecting the first hinge member of the first lifting member with the second hinge member of the second lifting member, and by hingedly connecting the second hinge member of the first lifting member with the first hinge member of the second lifting member, such that the lifting device may be placed over a cylinder and positioned at a desired location and the handles may then be urged toward one another and an outer wall of the cylinder to bear the first and second lifting members toward the cylinder to frictionally secure the device in the desired position for maneuvering of the cylinder, and wherein the first and second free ends of the body of the first lifting member are maintained in a spaced apart relationship relative to the first and second free ends of the body of the second lifting member corresponding to a desired gap distance, and the first and second hinge members of each lifting member each define a hinge point located a desired hinge distance vertically spaced from the first free edges of each of the lifting members, such that the ratio of the gap distance to the hinge distance is at least about 1.25.
