(under the class definition) Apparatus, (A) adapted to be rearranged to perform different functions or (B) adapted to be altered so as to operate in a different way or change its function or enhance its operation in some way by (1) disassembling the apparatus in some portion and then reassembling the apparatus with the same or different portion, (2) disassembling some portion from the apparatus, or (3) assembling some portion of the apparatus.
(1) Note. A mere adjustment of some part of the rotary expansible chamber device merely to perfect its cooperation with another part of the device is not considered proper for classification here. Such devices will be found in subclasses 104+.
(2) Note. A portion of a rotary expansible chamber device, such as for example a working chamber liner which is adapted to be reversed, replaced, removed or added to present a new working member engaging surface but which does not change the mode of operation of the device is excluded from this subclass, however, where such a change effects a change in the size or shape of the device, classification is in this subclass.
(3) Note. A reversible device in which is provided either a plurality of vanes or a plurality of abutments, some of which are placed in a nonworking position while the remaining ones are in a working position and vice versa depending on the desired direction of rotation of the working member is not considered to be convertible for classification here. Such devices are found in subclass 239.
