Abstract
Abstract This disclosure relates to a machine for securing articulated fasteners to articles, comprising a supporting frame, a container having a substantially cylindrical wall on said frame, a revolving body within said container having an axis of rotation coaxial with said cylindrical wall, a substantially cylindrical skirt member within said container spaced from said cylindrical wall thereof to define a narrow gap therebetween, said skirt member having a top edge defining a helically extending arraying guide, a setting-die, a conveying guide having one end confluently arranged with respect to an end portion of said arraying guide and another end thereof facing said setting-die, brush means secured on said revolving body to impart a random circular motion to fasteners loaded into said container and slide them along said arraying guide, motor and transmission means for imparting motion to said revolving body and said setting-die.

Claim 1
Independent Claim
326 words
A reciprocating setting-die for fastener setting machines, the fasteners being an articulated rivet fastener having a stem portion and an eyelet portion said stem portion having a loop bend on one end thereof, said eyelet portion being articulated on said loop bend, said loop bend extending transverse to the extension of said eyelet portion, thereby to form transverse protuberances with respect to said eyelet portion, the setting machine being of the type having a feed channel for the fasteners and a pusher member pushing the fasteners towards the setting-die and a fixed anvil member arranged in the reach of the setting-die lower end of stroke position and comprising a reciprocating block member and a movable jaw member hinged on said block member near a side thereof opposite the side facing said pusher member, said block member having a first clamping surface for the fasteners extending transverse to the direction of reciprocating motion stroke of said setting-die and said jaw member having another clamping surface cooperating with said first clamping surface in the clamping of fasteners, said clamping surfaces defining jaws opening towards said pusher member, spring means urging said movable jaw member in a closed position thereof, said movable jaw member having a hinge axis perpendicular to said direction of reciprocating motion, said movable jaw member having an arm extending perpendicular to said other clamping surface, said arm having a free end thereof hinged on said block member about a hinge axis perpendicular to said direction of reciprocating motion, and wherein said free end has an abutment surface positioned beyond said hinge axis with respect to said other clamping surface, said spring means having one end thereof engaging said block member and having another end thereof pressing against said abutment surface, and wherein said first and said other surface have seat portions adapted to the shape of said fasteners, said shape including at least one groove adapted to receive said transverse protuberances of said loop bend.
