Number: 29/243.521
Name: Metal working > Means to assemble or disassemble > Overedge assembling means > Annular work > With second workpiece inside annular work one workpiece moved to shape the other > Comprising driver for snap-off-mandrel fastener; e.g., pop (tm) riveter
Description: Apparatus wherein a first tool engages an annular end surface of a tube-like workpiece, which surface generally faces the device, which first tool includes a passageway coaxial with the tubular axis of that workpiece, and wherein a second tool functions within that passageway to engage a shank portion of a second workpiece extending through the tubular axis of the work and through the coaxial passageway, which first tool urges against the annular surface and which second tool reactively pulls against the shank with sufficient force moves the second workpiece with respect to the first and to ultimately exceed the tensile strength of the shank portion and thereby divide one portion of the shank from the remainder thereof, which remainder serves with the tubular first workpiece as a fastener.
