Device for Supporting Wheels for the Insertion of Arbors
|
John T. Kenworthy |
Flushing, Queens County, NY |
Abstract:
Almost all cylindrical or circular work having a central hole that is truly concentric io with its external convex surface has to be turned on an arbor or mandrel. Wheels, pulleys, gears, &c. are turned in this manner. In order that the work operated upon may be rotated against the cutting-tool and not slip, the arbor or mandrel on which it is turned is made with a slight taper, so that the farther on the arbor the work is driven the more securely it is held. The devices heretofore made use of for supporting the article while the mandrel is driven in have only been adapted to one size of arbor, and are hence objectionable. The object of this invention is to furnish a convenient means for the expeditious insertion and removal of arbors or similar devices from wheels or other articles where one piece of work requires to be driven into or out from another.
Claim:
The standard A, having a base, e, and side openings at a, a hollow top, b, and a projection, b', at one side, in combination with the pivot-pin d and the plate B, having holes therein of different sizes and resting upon the standard. |
