摘要：An apparatus for simultaneously or independently adjusting components in amachine wherein the components are movable along a track to change the positions oftools, tool holders or other mobile parts. The apparatus has an indexible feed screwwhich is parallel to the track and mates with discrete nuts, one for each adjustablecomponent and each rotatably connected to the respective component. The nut hasaxially parallel grooves for reception of pivotable pallets on the nuts to establishtorque-transmitting connections between the feed screw and selected nuts. The nuts canbe arrested against rotation with the feed screw by locking bolts which are engageablewith 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 ofthe feed screw and the nut is arrested so that it cannot rotate with the feed screw.
