(under the class definition) Apparatus (A) adapted to be rearranged to perform a different function or (B) adapted to be altered so as to operate in a different way or change its function in some way by (1) disassembling the device in some major portion and then reassembling the device with the same or different portion, (2) disassembling some major portion from the device, or (3) assembling some major portion to the device.
(1) Note. A mere adjustment of some part of the expansible chamber device, such as for example, an adjustable spring used to bias a working member in a direction of its movement, or a radially adjustable piston side wall portion is excluded from this definition, such features being classified below.
(2) Note. A portion of an 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 expansible chamber device is excluded from this subclass, however where such change effects a change in the size or shape of the expansible chamber device, classification is in this subclass.
SEE OR SEARCH THIS CLASS, SUBCLASS:
6, for an expansible chamber device in which the effective area of the working member end face is selectively variable.
13.41, for adjusting working member stroke by assembly or disassembly of a portion of the device. 128, for an expansible chamber device provided with special means, or so constructed as to facilitate the assembly or disassembly thereof.
133, and the search there noted for an adjustable spring device for biasing a working member in one direction of its movement.
169+, for a replaceable or reversible cylinder liner.
201+, for a piston having a radially adjustable side wall portion and especially subclass 204 for means to adjust the side wall portion radially comprising a shim element which may be selectively inserted or removed from between relatively movable piston portions.
