DEFINITION

Classification: 234/109

(under the class definition) Device provided with mechanism to condition one tool pair.

(1) Note. This subclass (109) uncludes devices wherein a member, when in effective position, engages and blocks actuation of an associated tool. Such a blocking member is not an interposer*, for it does not "engage a tool---for actuation".

(2) Note. For original placement in subclass 109, a patent must claim specific tool-selection mechanism.
