Abstract

A magazine for compactly holding and feeding therefrom a quantity of blind rivets to a specially configured rivet table of a blind rivet setting device. The magazine, as part of an automatic rivet feed mechanism, contains a thin elongated strip or ribbon of flexible material holding the mandrel tips pierced through the strip evenly spaced apart. The strip is drawn from the magazine through a transverse feed slot formed through the rivet table generally orthogonal to the longitudinal axis of the device. A spring biased retracting device continuously pulls the strip through the feed slot so that the next rivet in succession facing the rivet table is automatically drawn into axial alignment within the rivet table ready for positioning and setting into a work surface.

Dependent claims

A magazine for holding a quantity of blind rivets ready for use in an automatic rivet setting tool, said quantity of rivets connected in spaced relation along the length of an elongated strip of thin flexible material by having a distal portion of each rivet inserted therethrough said magazine comprising:

a cover having a bottom and a continuous cylindrical side wall extending from said bottom to define a generally circular open end of said cover;
a plurality of parallel elongated spacer sleeves connected in evenly spaced arrangement between a pair of spaced parallel end plates forming a spool;
said spool removably connected concentrically within said cover and having a first end plate of said pair of end plates positioned immediately adjacent said bottom and a second end plate of said pair of end plates positioned beyond said opening forming a gap between said second end plate and said opening, said gap having a width generally at least equal to the width of said flexible strip;
said quantity of rivets carried on said flexible strip being generally radially positioned within said cover with each rivet mandrel of each rivet of said quantity of rivets between two adjacent spacer sleeves of said plurality of spacer sleeves, the head of each rivet being positioned inwardly toward and adjacent a central axis of said spool when said flexible strip is wound in spiral fashion around said plurality of spacer sleeves;
a free end of said flexible strip extending outwardly through said gap from around said plurality of spacer tubes for engagement with the rivet setting tool.
