Rack-like Nut Thread Sector Patents (Class 269/186)
  • Patent number: 4574605
    Abstract: The forming machine includes a load station adjacent one end, an unload station adjacent the other end and a first work station, turnaround station and second work station spaced longitudinally in succession between the load and unload stations along a workpart flow path. Each work station includes a rotatable spindle fixed in position on one side of the flow path and a tailstock with a workpart support slidable toward the spindle transversely of the flow path. An overhead transfer mechanism is slidable along the flow path and carries multiple workpart transfer members such as grippers to transfer workparts successively from one station to the other along the flow path. First and second pairs of forming tools are spaced longitudinally to cooperate with the first and second work stations and are slidable longitudinally and simultaneously in engagement with first and second workparts rotatably and transversely supported at the respective work stations between the respective spindle and tailstock.

  • Patent number: 4438911
    Abstract: A quick set hydraulic work holding vise comprising an elongated stationary base plate member, a front stationary jaw fixed to the base plate member at a front end thereof and a rear jaw movable toward and away from the stationary jaw slidably movable along an elongated slide plate member supported for limited movement longitudinally. The slide member has an upwardly facing helical screw threaded channel and the movable jaw carries an interrupted worm screw interlocking device to interfit with the screw threads of the channel for locking the movable jaw longitudinally, which can then be locked against raising or skewing by tightening screw to compress the jaw on the slide plate member. A hydraulic piston is connected to the slide plate member for rapidly moving it and the movable jaw thereon to the gripping position.
