(under the class definition) Apparatus comprising means designed to facilitate the removal or replacement of a part of an expansible chamber device.
(1) Note. Excluded from this subclass are devices including mere securing means for either a cylinder or piston portion, which means are so located as to be easily accessible, for example, means for securing piston parts together such as
bolts which extend through the piston face for easy accessibility upon removal of a cylinder end wall is excluded. Included in this subclass are, for example, an expansible chamber device combined with a tool for disassembling or assembling a part of the device, cooperating means between a cylinder and piston for facilitating the insertion or removal of the piston from the cylinder, special openings through which a tool may be inserted to assemble or disassemble a part of the device, or specific structure of a piston having a part removable therefrom which structure is specifically disclosed as for facilitating assembling or disassembling such part from the piston without the use of separable fastening means.
