Abstract:
A tool for launching wiper plugs into a casing string in a gas or oil well during cementing operations employs a collet-like mechanism carrying radially-movable jaws arranged to retain a plug in a fluid flow path when the tool is in a closed position, and to release the plug into the fluid flow path when the tool is in an open position. Selection of the desired operational position of the plug launcher (i.e., open or closed) is effected by actuation of an axially-movable sliding sleeve. Alternative means for actuating the sliding sleeve include rotary actuation about the tool's longitudinal axis, rotary actuation about a radial axis generally normal to the longitudinal axis, rotary actuation about a generally tangent axis, and pneumatic or hydraulic actuation. The tool may be adapted to carry multiple wiper plugs for sequential launching into a casing string.

Claim (Index 4):
A plug-launching tool as in  claim 3  wherein the actuation means actuates the sliding sleeve by rotary actuation about a longitudinal axis of the housing.
