Application No. 09/368,781
Root's invention relates to pliers having cutting-jaws and has for its object to
provide a tool of this class having removable, interchangeable, and reversible cutters
provided with a number of cutting-edges, whereby the cutters can be adjusted to bring a
new cutting-edge into play when one edge has become worn, and to enable the
substitution of new cutters when desired. Referring to the drawings, A A designate the
two members of a pair of pliers. The members A each comprise a handle 13 and a jaw
C. Intermediate the jaws and handles and connecting the same integrally are circular
disks D D, the latter terminating at their inner faces one-half the breadth of the
members A below the open side of the latter, forming circular recesses d d. Thus when
the members are in relative position the disks D fit within the respective recesses and
turn therein. The members are secured together by a pivotal screw E, passing through
a smooth eye e, provided centrally through one of the disks D and secured within a
coincident threaded eye e' in the other disk.
H H designate cutting-plates, which are triangular in shape and preferably
truncated at the apexes, each of the three edges of the plates constituting an
independent cutting edge. The cutting-edges of the plate are formed by beveling the
latter from one side, as shown. The cutting-plates are disposed in corresponding
sockets or recesses I I, provided in the inner faces of the disks D. Each cutting-plate is
provided with a central aperture j for the reception of a securing-screw J, the latter
