(under the class definition) Device comprising means to direct or confine the material* acted upon or affected only by external force.
(1) Note. The mere support, or prevention of downward movement, of material* 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 material*, but to conduct it, or facilitate its deflection, to a different level) has a guiding function.
(2) Note. The "passive guide", in this and indented subclasses, performs its function without the necessary application of power thereto; it directs, deflects, orients, etc., the material* without furnishing any propelling force in the general direction of material* movement.
