(under subclass 469) Device provided with means to move at least one of the cutters of a tool pair into and out of cooperative cutting relation with respect to the other cutter of said tool pair.
(1) Note. See (4) Note of subclass 469 for definition of "Tool pair".
(2) Note. To be classified herein, a patent must include disclosure of a movement of one cutter away from and out of cutting relation with respect to the other cutter of the tool pair (this movement usually being for the purpose of permitting the work to be threaded through a cutting zone). A mere adjustment of one cutter relative to another cutter
while they remain in contact with or in cooperative cutting relationship with each other will not suffice for placement in this subclass, but will be found in subclasses 503, 504 and 507 below.
(3) Note. The separation of the cutters one from the other may also be for the purpose of inspecting, removing, replacing or substituting one or both of the cutters. For other such devices, see subclass 481.
