ABSTRACT:
This invention relates to a ferrule dispenser for dispensing stud welding ferrules and to a package of ferrules for use with the dispenser. The dispenser comprises a rod that supports a spring loaded cam system. The cam system moves relative to the rod and includes a compression spring and a cam. The spring and cam work together to bias a pair of ferrule release pins inward and outward of the rod, selectively holding ferrules on an outer surface of the rod or releasing them onto a work surface. The package of ferrules used with the dispenser includes multiple sets of ferrules, each set including multiple ferrules uniformly stacked on a spindle. Each spindle has one open end that can pass through an opening in a handle of the dispenser and down a center bore of the dispenser for loading the ferrules from the spindle onto the dispenser.
