<p>A tool feed module for a portable lathe machine tool includes a tool block carrying a cutting tool driven by a feed screw incrementally advanced during a cutting procedure by an actuator arm contacting a striker device located on the tool housing. The actuator arm drives the feed screw through an actuator shaft and a one-way drive device permits the actuator arm to pivot in opposite directions while driving the feed screw in increments during pivotal motion in a single direction. To enable reverse rotation of the feed screw and withdrawal of the cutting tool to a starting position rapidly, the actuator shaft is connected to the one-way drive device through a releasable connection that permits rotation of the drive screw by the actuator shaft independently of the one-way drive device.</p> |
