Abstract
An apparatus for simultaneously or independently adjusting components in a machine wherein the components are movable along a track to change the positions of tools, tool holders or other mobile parts. The apparatus has an indexible feed screw which is parallel to the track and mates with discrete nuts, one for each adjustable component and each rotatably connected to the respective component. The nut has axially parallel grooves for reception of pivotable pallets on the nuts to establish torque-transmitting connections between the feed screw and selected nuts. The nuts can be arrested against rotation with the feed screw by locking bolts which are engageable with selected teeth of annuli of teeth on the nuts. A nut will shift the respective component along the track when the respective pallets are expelled from the grooves of the feed screw and the nut is arrested so that it cannot rotate with the feed screw.
