DEFINITION

Classification: 234/81

(under subclass 79) Device in which the sensing means, in response to detection of a pattern indicium or characteristic, moves a selected tool, or initiates the transmission of force from a source of energy to move said tool, into such position that (1) an actuating power train is completed to drive said tool through its working stroke, or (2) a latching or blocking mechanism is caused to hold said tool in operative position while a cooperating tool is actuated.

(1) Note. No interposer* is employed in mechanism of this type.

SEE OR SEARCH THIS CLASS, SUBCLASS:

117+, for a tool selection means in general which effects completion of a power drive train to a selected tool without the use of an interposer.
