Abstract: An apparatus and a method for delivering a workpiece to and from a machine table. The apparatus includes a rotatable plate and a pallet. The workpiece is detachably mountable to the pallet. The rotatable plate is movable with respect to the pallet. The pallet is movable along a pallet carriage. A screw is movably mounted within the screw housing and the screw housing is connected to the pallet. A driver is attached to the screw and moves the screw within the screw housing and the driver operates to engage the screw and move the pallet in a linear direction to and from the machine table.

Abstract: A method and apparatus for delivering workpieces to and from a machine table. This invention also relates to an apparatus for receiving at the machine table workpieces which are delivered to and retrieved by the delivery system. Carts move with respect to a surface, such as a floor surface. The carts move and deliver pallets to a loading station that uses a loading arm to deliver pallets with workpieces to and from a machine table.

Abstract: A table extender for a milling machine which includes upper and lower work support members with the lower work support mounted on the table or bed of a milling machine and a pair of shot pins moveably mounted in the lower work support and engageable in openings in the upper work support. The upper work support is moveable on slides relative to the lower work support and a locking handle is provided so as to lock and unlock the shot pins to allow the upper and lower work supports to be moved relative to each other.

Abstract: A fast change set-up device for work on work supports wherein work blanks can be mounted to a number of work supports prior to machining and the upper work support can be quickly attached to a lower work support and locked thereto by rotating a handle so that the next piece can be machined. The shaft carries four cams for driving spring biased bolts which engage in grooves formed in locking pins and the cams have an indentation for locking the bolts in the grooves to hold the upper and lower work supports together so that machining can occur. After machining the upper work support can be removed from the lower work support and a second upper work support can be mounted to machine another workpiece.
