ABSTRACT:
A chuck for handling hollow, cylindrical glass articles, such as used in solar energy installations, is disclosed wherein such glass articles generally are in the form of concentrically assembled glass tubing having a coated exterior surface. In the orientation in handling these types of glass articles, a polypropylene, integral chucking mechanism, which is adapted to be inserted within the glass article and actuated after insertion, expands to engage the interior surface of the glass article and maintains the article in a specific, desired, fixed position. The inclusion of a cone member on the chuck supporting structure and a V block guide assist in the proper alignment of the glass article relative to the clamp and its support.
