Abstract

Piercing tool for arms of I-beams, U-beams, etc., comprises a conveyor for the I-beams defining a reference plane for a web portion of the I-beam, a scanner for sensing the position of the surface of the web portion relative to the reference plane, and an indicator showing the distance between web portion and plane. A hole-forming device is movable by a positioning device into a desired relative position, then aligned precisely with the web portion near the flange portion. The scanner consists of two diametrically opposed, counter reciprocating elements mounted one on each side of the web portion and connected to levers joined by a diagonal link rod.
