ABSTRACT:
An adjustable pallet for securing a plurality of elongated workpieces to the work-table of a machine tool. The pallet comprises a rectangular, substantially planar base having three horizontally-disposed plates attached thereto. Each of the three plates has an array of apertures therethrough arranged in a predetermined grid pattern. The grid patterns on the three plates correspond to one another. The middle of the three plates is adjustably slidable with regard to the top and bottom plates, which are fixedly attached to one another. The top and bottom plates are attached to one another with their respective apertures in registry or alignment. The pallet utilizes thumb-nut assemblies to threadedly adjust the displacement of the middle plate with regard to the top and bottom plates. The middle plate is adjustably movable to a position that allows the apertures therein to be in registry or alignment with those of the top and bottom plates. When the apertures of the three plates are in registry, an elongated workpiece can be inserted into one or more of the through opening formed by the aligned apertures. With the workpieces inserted into the desired through openings, the operator can rotate the thumb-nut assemblies to move the middle plate and the apertures therein out of alignment with the apertures in the top and bottom plates. The displacement of the middle plate against each workpiece thus secures each workpiece within the pallet.
