摘要

Improvements in the adjustable and interchangeable automatic advancement clutch devices for machine tools, characterized in that the disc or drive plate is integral with an annular part, provided with three vertical planes in the shape of a star, equally spaced, on which three are adjusted rollers, slidable under the pressure of their respective springs, on a bushing that is joined to the advancing spindle and when the plate moves forward, is automatically engaged by the rollers and through said bushing with the spindle, printing the movement previously adjusted; while in its recoil movement, under the force of a recuperating spring, said rollers automatically disengage from the spindle, and slide on the same coupling sleeve, returning all the pieces to their initial position.
