Patent number: 3933019Abstract: A tool for installing an internally threaded tubular rivet. A pair of levers are pivotally connected together with one of the levers having a portion with a hole therein. A tubular anvil is received in the hole and is secured to the lever. A rod extends axially through the anvil and is relatively movable with respect to the anvil. A knob or the like is mounted on the rod and is spaced axially from the anvil for rotating the rod relative to the anvil. The knob has an abutment thereon which engages the other lever so that a relative movement between the two levers will effect a relative movement between the rod and the anvil.Type: GrantFiled: October 4, 1974Date of Patent: January 20, 1976Assignee: Borroughs Tool & Equipment CorporationInventors: Gary E.
