![]() ![]() The remaining portion of said shank extending through the cylindrical section of said circular hole and through said circular tapered part and projecting beyond the shank of said second member the end of said remaining portion which projects beyond said shank of the second member being headed over the second member forming in one step a round overlapping head like said rivet head and expanded tightly into said circular tapered part and at the same time being expanded into tight engagement around the intersection of said circular tapered part with the outer surface of said second member underlying said overlapping head and further expanded into tight engagement with said cylindrical section of said circular hole and thereby forming a united, permanently set, non-rotatable joint of the shank of said rivet with the shank of said second member, and sliding pivot fastener connection with a spaced clearance of predetermined size between the head of said rivet and said side surface from which said rib extends, thereby enabling said shank of said rivet to be freely slidable back and forth along said slot when said handles of said pliers are rotated to a position in which said rib like tongue and said grooves are disengaged.Ä¥. This results in the shank 11 of the rivet being nonrotatably united with the jaw 2. When the projecting end 12 of the rivet is headed over the jaw 2 as indicated at 17, the shank 11 is expanded into the tapered section 16 of the hole 13 and is also expanded into tight engagement with the cylindrical section 15 of the hole 13. The outer part of the hole 13 is tapered as indicated by the numeral 16, the angle of taper being a locking taper. ![]() The end of the hole 13 adjacent the jaw 1 is cylindrical, as indicated by the numeral 15. The end 12 of the rivet projects through a hole 13 in the jaw 2 and beyond the outer surface of the jaw 2. The head 10 of the rivet overlaps the outer surface of the slot 5 in the same manner as the head of the bolt, and the shank 11 of the rivet slides in the slot 5 as freely as the shank of the bolt it replaces. To increase the strength of the pivot connection, there is substituted for the nut and bolt a rivet 9 having a head 10 corresponding to the head of the bolt it replaces, and a shank 11 the same size as the shank of the bolt.
