High capacity magazine for automatic feed blind rivet setting tool

Abstract

A magazine for holding a larger quantity of blind rivets ready for use in an automatic rivet setting tool. The rivets are connected in spaced relation along the length of an elongated flexible rivet carrying strip or ribbon by having a distal portion of each mandrel inserted or pierced through the carrying strip. The magazine preferably includes an upwardly tapering conical or truncated conical shaped support surface held for rotation about a preferably upright central spool axis on a support stand. The carrying strip is loaded with rivets and spiral-wound around and flat against the outer support surface with the head of each rivet extending away from the spool axis and the distal portion positioned against the outer surface so that each rivet is automatically positioned in an outwardly extending fashion from the support surface.

1 . A magazine for holding a larger quantity of blind rivets ready for use in an automatic rivet setting tool, the rivets being connected in spaced relation along the length of an elongated flexible rivet carrying strip by having a distal portion of each mandrel inserted or pierced through the carrying strip, said magazine comprising: 
 a conical or truncated conical shaped support surface held for rotation about an upright central spool axis on a support stand;    each rivet being carried on the carrying strip so that, when said carrying strip loaded with rivets is spiral-wound around and flat against said support surface with the head of each rivet extending away from the spool axis and the distal portion thereof positioned against and extending outwardly from the outer surface.    
   
   
       2 . A magazine as set forth in  claim 1 , wherein: 
 said support surface includes a plurality of rivet carrying strip support shafts or prongs which outwardly extend from, and rigidly attached to, or are formed as a part of said support surface;    said support shafts or prongs support and maintain against gravity a spaced array of the spiral wound arrangement of said rivet carrying strip from the bottom to the top of said support surface.    
   
   
       3 . A magazine holding a larger quantity of blind rivets ready for use in an automatic rivet setting tool, comprising; 
 an elongated flexible rivet carrying strip;    said rivets being held in spaced relation along the length of said carrying strip by having a distal portion of each mandrel inserted or pierced through said carrying strip;    said magazine including a conical or truncated conical shaped support surface held for rotation about an upright central spool axis on a support stand;    each rivet being carried on the carrying strip, said carrying strip being spiral-wound around and flat against said outer support surface with said distal portions being positioned against said outer surface wherein each rivet is automatically positioned in radially extending fashion away from said outer surface.    
   
   
       4 . A magazine as set forth in  claim 2 , wherein: 
 said support surface includes a plurality of rivet carrying strip support shafts or prongs which outwardly extend from, and rigidly attached to, or are formed as a part of said support surface;    said support shafts or prongs support and maintain against gravity a spaced array of the spiral wound arrangement of said rivet carrying strip from the bottom to the top of said support surface.
