Abstract: A gauging attachment for machines utilizing a pantograph mechanism including a gauging assembly having a master gauge plate adapted to be coupled to the pantograph mechanism. A series of gauges are selectively engageable with the gauge plate to correctly position the workpiece. A clamping plate secures the workpiece to the master plate and in engagement with the gauge. The entire gauging assembly moves in response to motion imparted to the pantograph at a stylus. The stylus is traced along templates selectively interchangeable in a removable template tray. The attachment is adjustable and once set maintains a predetermined position with respect to the workpiece to facilitate repetitive operations without further adjustment.
