A thread making device that has a thread form with controlled height adjustment. The thread making device is formed from a threading cartridge mounted on a threading bar. A thread form with a cutting edge is secured in a pocket on the threading cartridge bounded on one side by an adjustable height clamp, whose position relative to the threading cartridge is controlled by serrated faces on the adjustable height clamp and the threading cartridge. The thread form has a thickness extending in a wear direction, and the serrations of the serrated faces allow height adjustment of the adjustable height clamp in the wear direction.

The present invention provides a tool for bar peeling comprising a rotatable cutter head with circumferentially spaced toolholders each of which is provided with a U-shaped recess along one of its side surfaces. A wedge shaped element is longitudinally displaceable in the U-shaped recess so that an insert carried by the toolholder in subjected to radial adjustment upon a longitudinal displacement of said wedge shaped element.

A precisely adjustable cutting tool holder for a machine tool employs an eccentric shaft to directly engage and thereby to pivot a tool holding part with respect to a stationary part that is secured to the machine tool. Threaded members that engage another eccentrically oriented member may be used to minimize backlash between moving parts of the mechanism.

A tool holder assembly comprises a support member connectable to a machine tool and having therein a linear slideway. A slide member is slideably mounted in the slideway and the slide member is provided with a tool-holding recess for releaseably holding a work tool. An adjustment device coacts with the support member and the slide member for selectively adjusting the position of the slide member along the slideway to thereby accordingly effect adjustment of the work tool. The adjustment device comprises a screw mounted on the support member for rotational movement but not translational movement and the screw has a threaded portion which extends through a cavity provided in the support member. The slide member is provided with a threaded nut which extends into the cavity and in threaded engagement with the screw so that angular displacement of the screw effects linear displacement of the slide member along the slideway. A manually graspable knob is connected to the screw to enable manual adjustment of the slide member.

A fluid driving apparatus is contained in one of the ends of two lever arms designed to pivot about a common fulcrum point. The driving apparatus comprises a piston limited to move in a direction perpendicular to its axis, an arcuate expansible chamber in each of the lever arms, wherein each chamber is designed to receive one end of the piston, means for providing fluidic communication between the chambers and means for supplying fluid under pressure to the chambers thereby expanding said chambers and applying a force to the lever arms.
