Abstract

Abstract A rivet setting tool for blind rivets is disclosed which, in construction, includes gripping means for grasping the mandrel of a blind rivet and pulling means coacting with the gripping means for retracting the gripping means to pull the mandrel into the eyelet of the rivet to set same. The tool also includes specially constructed spring means cooperatively engaging the gripping and pulling means which operates to automatically initiate retraction of the pulling means to move the gripping means into contact with the mandrel under a relatively light pressure sufficient to hold the rivet in place relative to the tool. The tool further includes means for actuating the gripping and pulling means which includes a pivotally mounted handle supported by specially constructed means reducing wear and tear on the support structure. A special wear-resistant insert for the nose piece of the tool is also disclosed.

Claim 9
Dependent Claim 77 words
In a rivet setting tool for blind rivets having a body formed with a hollow driving portion made of a soft metal, a pair of co-acting jaws within said driving portion and a bored nose piece for receiving the mandrel disposed within a hole in said driving portion adjacent said jaws, the improvement which comprises a tubular insert of a hard metal disposed within said hole in intervening relationship to said nose piece and said driving portion.
Claim 10
Dependent Claim 24 words
A structure as described in claim 6 wherein said insert is made of mild carbon steel and said driving portion is made of aluminum.
Claim 11
Dependent Claim 44 words
