Abstract
Abstract Apparatus having a pallet for supporting a workpiece for movement relative to a tool. The pallet is removably mounted on moving means operative to move the workpiece on the pallet relative to the tool. The moving means comprise a movable support for the pallet, motive means, and a resilient, arcuate interconnection between the support and the motive means. The pallet has means for securing the workpiece against movement relative to the pallet and an aperture for providing tool access to portions of the workpiece where the tool operates on the workpiece.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
173 words
A coupling device for resiliently mounting a pinion driven rack to a workpiece support which is mounted for movement with the rack comprising: A. a toothed rack constructed for engagement with a motor drive pinion; B. a workpiece support mounted for movement in operative relation through the rack to the motor driven pinion; C. first mounting surfaces, one at each end of the rack, the plane of said surfaces being parallel to the direction of movement of the rack; D. second mounting surfaces each of which is constructed on the workpiece support for adjacent alignment with a respective first mounting surface; and E. a pair of resilient leaf springs secured across the adjoining first and second mounting surfaces at each end of the rack to mount the rack to the workpiece support in a manner which provides for direct, non-resilient transmission of the drive forces from the pinion through the rack to the workpiece support and allows for resilient displacement between the rack and the workpiece support to compensate for other interacting forces.
