DEFINITION

Classification: 411/96

Having plural parts, one comprising a keeper:

(under subclass 92) Device wherein the member consists of two or more coacting pieces, at least one of which functions merely to prevent another piece, or pieces, from moving out of operative engagement with the bolts or nuts.

(1) Note. While some of the art of this subclass strongly resembles that of subclass 94 above, a closer examination will reveal that the fishplates of this art (96) are not "special" within the meaning of that subclass (94) and therefore are treated as comprising only substructure; see (1) Note and (2) Note of subclass 94.

(2) Note. The part which serves a holding function is, in some instances, no more than a spike for anchoring a disclosed rail assembly.
