DEFINITION

Classification: 269/216

(under subclass 86) Device including an actuating* means to move at least one jaw with respect to another.

(1) Note. Generally, a patent providing for relative movement of jaws not clearly encompassed by the concept of adjustment* is considered to set forth the use of actuating

means and such patent will be placed here (subclasses 216+).

(2) Note. A patent claiming an actuating train, which train includes, in series, two or more of the specific actuating means set forth below, will be placed as an original in the first or superior subclass providing for any of said claimed actuating means and a cross reference copy placed in subclasses providing for other claimed actuating means; e.g., a patent claiming the use of a toggle mechanism to drive a cam actuating means will be placed, as an original, in subclass 228 with a cross reference in subclasses 229+.
