Abstract
An improved escapement mechanism is provided including a reciprocating nesting block which periodically advances a rivet or other fastener to a delivery tube. The escapement mechanism includes a cover plate mounted to the housing and secured in place by a pair of locating pins and a thumb screw assembly which makes removal of the cover plate very simple. The nesting block is provided with an elongated slot which is engaged by a head portion of an end fitting attached to drive rod of a drive mechanism. The sliding engagement of the end fitting with the elongated slot of the nesting block provides for easy changeover to other nesting blocks as well as improved maintenance and cleaning.
