ABSTRACT:
There is disclosed a chuck assembly for engaging the inner surface of a hollow substrate comprising: (a) a housing having an open end and defining a passageway in communication with the open end; (b) a partially hollow elastic boot defining an entry hole and an inner surface wherein the boot when stretched decreases in cross-sectional dimension, and wherein the boot engages the housing, whereby the hollow portion of the boot is in communication with the passageway; and (c) a movable, boot stretching member disposed in the passageway and adapted to engage the inner surface of the boot, wherein movement of the member in a direction to stretch the boot decreases the cross-sectional dimension of the boot, thereby permitting insertion of the boot into the substrate, and wherein movement of the member in the opposite direction increases the cross-sectional dimension of the boot, thereby permitting engagement of the boot against the inner surface of the substrate.
