Interference No. 103,414
The subject matter of this interference is a drive
rivet, i.e., a rivet which carries a pin that when driven home
forces the rivet into aligned holes in two or more members to be
joined together and then causes the entry end of the rivet,
divided into quadrants, to spread apart and fix the rivet in
place. The drive rivet disclosed in each party's involved
application has a shank consisting of two cylindrical shank
portions of different diameters joined together by a tapered
shank portion.
