DEFINITION

Classification: 134/44

(under the class definition) Apparatus in which some element or control of the apparatus is operated or controlled by engagement with the work or by a holder for the work that is separate from the apparatus.

(1) Note. Apparatus having interconnected or interengaging parts so that motion of one part causes motion of another, is not in this and the indented subclasses, but is in appropriate following subclasses.

(2) Note. In this subclass, for example, are devices in which relative motion between the work and fluid applying means causes sliding or rectilinear motion of the member immediately moved to operate or control a fluid controlling valve.
