Abstract
The pneumatically actuated core chuck described and shown has a compression ram movable with respect to a sleeve to force jaws to expand outwardly for engagement of the interior of a core of web material. The jaws are pivotally mounted by means of links extending from the compression ram. The ram is mounted on a piston movable in a cylinder for actuation by the introduction of air under pressure into a chamber behind the piston.
Claims11
A fluid actuated core chuck comprising a generally cylindrical compression ram mounted on a piston for linear movement;
- a sleeve surrounding a forward end of said ram and a plurality of elongated jaw members pivotally connected to the compression ram and movable radially outwardly with respect to the axis of said compression ram upon forward movement of said ram whereby surfaces of the jaw members engage the inner surface of an opening through a core.
A fluid actuated core chuck having a plurality of jaw members mounted for radially outward movement to engage the inner surface of an opening through a core, each of the jaw members being pivotally mounted by means of one or more links on a generally cylindrical ram movable with respect to a generally tubular sleeve which sleeve has openings accomodating movement of the jaw members and which sleeve surrounds a forward portion of the ram, a rearward portion of the ram being affixed to a piston which is slidably movable within a cylinder.
