Abstract
Abstract This invention concerns the construction of a simple yet sturdy multipurpose apparatus which as a series of stands, hangers, or both, can be used to support a rotatable tube. The primary object of the invention is to provide such a construction which is simple to fabricate. A feature of the construction is that the apparatus can be assembled either as a stand or hanger merely by a different geometric arrangement of the same parts with a simple bolt or pin locking thereof.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
254 words
In an apparatus for supporting a rotatable tube, a pair of vertically disposed horizontally spaced apart support members, each of said support members having a hole therethrough, the axes of said holes of said pair of support members being inclined to converge toward each other to a point vertically below said holes, a cross member having end portions angled from the center portion thereof, the angle between the longitudinal axes of said end portions and the longitudinal axis of said center portion of said cross member being substantially the same as the angle of the axes of said holes of said support members to the longitudinal axes of said support members, each end portion of said cross member being disposed through said hole through one of said support members, securing means connected to said end portions of said cross member for preventing said cross member from being withdrawn from said support members, a pair of substantially U-shaped plate members, each of said plate members being carried on one of the end portions of said cross member between said support members, means securing each of said plate members to said en portions of said cross member so that the longitudinal axes of the legs of said plate members are inclined upwardly and toward a point between said support members and within a plane including said support members, a pair of rollers, each of said rollers rotatively carried between the legs of one of said plate members for rotatively carrying a rotatable tube on said rollers.
Claim 2
Dependent Claim
254 words
In an apparatus for supporting a rotatable tube, a pair of vertically disposed horizontally spaced apart support members, each of said support members having a hole therethrough, the axes of said holes of said pair of support members being inclined to converge toward each other to a point vertically below said holes, a cross member having end portions angled from the center portion thereof, the angle between the longitudinal axes of said end portions and the longitudinal axis of said center portion of said cross member being substantially the same as the angle of the axes of said holes of said support members to the longitudinal axes of said support members, each end portion of said cross member being disposed through said hole through one of said support members, securing means connected to said end portions of said cross member for preventing said cross member from being withdrawn from said support members, a pair of substantially U-shaped plate members, each of said plate members being carried on one of the end portions of said cross member between said support members, means securing each of said plate members to said en portions of said cross member so that the longitudinal axes of the legs of said plate members are inclined upwardly and toward a point between said support members and within a plane including said support members, a pair of rollers, each of said rollers rotatively carried between the legs of one of said plate members for rotatively carrying a rotatable tube on said rollers.
Claim 3
Dependent Claim
78 words
In an apparatus as defined in claim 1, wherein said end portions of said cross member extend through said holes in said support members so that the tip portions of said end portions extend outwardly of said support members, and wherein said securing means connected to said end portions of said cross member for preventing said cross member from being withdrawn from said support members comprises pin means carried by said extending tip portions of said end portions.
Claim 4
Dependent Claim
66 words
In an apparatus as defined in claim 1, wherein the porTions of said U-shaped plate members carried on said end portions of said cross member are contiguous to the side and bottom walls of end portions, and wherein said means securing each of said plate members to said end portions comprises pin means extending through the contiguous sidewalls of said plate members and said end portions.
Claim 5
Dependent Claim
66 words
In an apparatus as defined in claim 1, wherein the ends of the legs of said U-shaped plate members extend above the outer circumference of said rollers so that a rotatable tube having a radially projecting ring thereabout is supported on said apparatus with the edge of said ring on said rollers and between the upwardly extending ends of said legs of said U-shaped plate members.
Claim 6
Dependent Claim
193 words
In an apparatus as defined in claim 1, wherein said end portions of said cross members extend through said holes in said support members so that the tip portions of said end portions extend outwardly of said support members, said securing means connected to said end portions of said cross member for preventing said cross member from being withdrawn from said support members comprises first pin means carried by said extending tip portions of said end portions, the portions of said U-shaped plate members carried on said end portions of said cross member being contiguous to the side and bottom walls of said end portions, said means securing each of said plate members to said end portions comprises second pin means extending through the contiguous side walls of said plate members and said end portions, and the ends of the legs of said U-shaped plate members extending above the outer circumference of said rollers so that a rotatable tube having a radially projecting ring thereabout is supported on said apparatus with the edge of said ring on said rollers and between the upwardly extending ends of said legs of said U-shaped plate members.
Claim 7
Dependent Claim
19 words
In an apparatus as defined in claim 5, wherein said support members and said cross member are cylindrical members.
