Another object of the invention is to provide an im

wherein the removed small group of papers is at all times
securely held together in the proper assembled order,
until such group is again replaced in the pile.
Still another object of the invention is to provide an
improved paper fastener as above set forth, wherein the
operation of replacing the removed sheet or sheets and
of replacing the said group may be easily and quickly
in the papers and are operable to releasably secure the 10 effected.
