ABSTRACT:
A portable chuck for dispensing under tension a roll of wrapping material wound about a tubular core is disclosed herein. The portable chuck includes an expandable spindle insertable within one end of the tubular core, and a handle for selectively expanding the spindle so as to create a braking force between the outside surface of the expandable spindle and the inside surface of the tubular core. The chuck is formed from first and second chuck pieces, each of which includes a semi-cylindrical spindle portion, collar, and handle portion. The fulcrum means is disposed between the first and second adjacent chuck pieces above the collar of each for allowing a relative rocking motion between the first and second adjacent chuck pieces, whereby the spindle portions are drawn away from one another at a mechanical advantage as the handle portions are manually squeezed toward one another.
