ABSTRACT:
An apparatus for operating a loom heddle comprises a drive shaft centered on, rotatable about, and defining an axis, and an eccentric carried on the drive shaft, rotatable relative thereto about the axis, and formed with an axially extending guide. A crank connects the eccentric to the heddle for displacement of the heddle between end heddle positions as the eccentric rotates about the axis. A drive disk rotationally fixed on the drive shaft adjacent the eccentric is formed with at least one recess axially alignable with the guide. An entrainment bolt is axially displaceable in the guide between an extended entrainment position projecting axially in one direction therefrom into the recess of the drive disk and thereby rotationally coupling the drive disk and eccentric together and a retracted position disengaged from the recess for relative rotation of the drive disk and eccentric. A switch element is provided that is operatively engageable with the bolt to displace it axially between the positions.
