Abstract

180,458. Salt, G. R. March 12, 1921. Rivet-extractors.-A rivet-extractor for use more especially in forcing out the rivets of driving-chains and of the type adapted to extract a pair of rivets simultaneously in which forked means are provided for holding the chain with a pair of rivets in coaxial relationship with a pair of extracting punches, has the pair of punches geared together so as to advance at the same rate. the body of the device being formed with a toothed anvil engaging between the rollers of the chain for locating the latter accurately with respect to the punches. As shown, the device comprises a flanged or channel block d provided with a handle e, the flange c having two tapped holes, one with a right-hand thread and the other with a left-hand thread, in which holes are mounted correspondingly threaded spindles b carrying the punches a. Said spindles b are geared together by pinions f, one of which is formed with a socket l for a tommy bar m. The other flange h is formed with teeth i adapted to engage between the chain rollers so as to locate a pair of chain rivets k exactly opposite the punches.
