(under the class definition) Apparatus wherein an entire molding or shaping device is supported in such a manner as to facilitate its movement from one location to another.
(1) Note. Included herein are molding devices mounted on tracks, trucks, skids, boats, etc.. The mere statement that it includes handles etc., will not being a patent here. For portable devices see appropriate subclasses below and in Class 249, Static Molds; however, wheels and tracks, per se, in the absence of means to move the apparatus, would not indicate classification in Class 425, but in Class 249.
(2) Note. Excluded from this subclass are devices wherein one portion of an apparatus is mounted on a transportation means for the purpose of moving it with respect to another portion of the apparatus without relocating the entire molding apparatus to a different site. Such devices are in appropriate subclasses below. Also excluded are devices in which a mold is repositioned in such a manner that a newly formed structure will be connected to a previously formed structure. For such devices see appropriate subclasses below, especially subclasses 63+.
