DEFINITION

Classification: 83/438

(under the class definition) Apparatus provided with passive means which is operative to define or limit the path of movement (i.e., to direct, wholly or partially, the course) or moving work, or to orient such work.

(1) Note. The mere support or prevention of downward movement of work under the influence of gravity is not significant as a guiding function. An inclined plane or the like, (which is utilized not for mere support of the work, but to conduct it or facilitate its deflection to a different level) has guiding function.

(2) Note. The "passive means", in this and indented subclasses, performs its function without the application of power thereto; it directs, deflects, orients, etc., the moving work without furnishing any propelling force in the general direction of work movement.
