Abstract
A pile threading device (14) for threading sheet piles (10, 12) and including a box-type frame or body (20) comprising a plurality of connected frame members. An upper slide (44) is mounted on body (20) for relative sliding movement and has a pair of opposed jaws (54, 56) thereon for clamping or gripping the undriven pile (12) for lifting the threading device (14). A pivoted stop bar (70) on the slide (44) engages a side edge (12C) of the undriven pile (12) when the pile (12) is initially positioned on the slide (44)for accurate positioning of the undriven pile (12) on the slide (44). One of the jaws (56) is held in a predetermined fixed relation by an adjustable nut (66) which is positioned at a predetermined position on externally threaded shaft (60) mounting the jaw (56). Roller frames (29, 30) carry rollers (32) for engaging opposed sides of the driven pile (10). One roller frame (30) is mounted for sliding movement on shaft (34) against compression spring (38) to provide a cushioned movement of frames (29, 30) away from each other.
