DEFINITION

Classification: 411/81

THREADED FASTENER LOCKED TO A DISCREET SUBSTRUCTURE (E.G., PLATE, RAIL, WHEEL):

(under the class definition) Device comprising a fastener in the nature of a threaded bolt or a threaded nut, or an interthreaded bolt and nut, and means for either preventing or limiting the turning of the bolt or the nut, or both of them, about its longitudinal axis relative to a claimed substructure (e.g., a base, a panel, a surface, an art device or, more generally, a workpiece) with which one or the other, or both, is associated.

(1) Note. The substructure is involved with the bolt or the nut in performing a fastening function; for example, the substructure may be the recipient of an object which is attached to it by the bolt or nut, or the bolt or nut may be serving to fasten two or more substructures together, and so forth, in some instances the rotation restricting means, or a part thereof, is formed integrally with the substructure.

(2) Note. The substructure may not be claimed; however, for purposes of classification herein, it should be treated as being present if it performs an indispensable function in restricting the rotation of the bolt or the nut.

190+, for a threaded bolt and nut and means for coupling them to one another against relative rotation.

238, Railways: Surface Track, 262, for a railway track having one or more rails and wherein, at a butt joint between two sections of a rail, at least one splice bar is provided and further wherein bolts and nuts, and means for locking them against rotation, are included for connecting the splice bar to the abutting rail sections. While this and the indented subclasses take such structure of the splice bar or rail section as relates to the locking thereto against rotation of one or more bolts or nuts utilized in joining a splice bar to one or more rail sections, the inclusion of, for example, a second, parallel rail, a tie, a tieplate, a roadbed feature, etc., is sufficient to require classification in Class 238.

403, Joints and Connections, appropriate subclasses for connections between two or more members which involve greater specificity of the members than merely the manner in which they are adapted to serve as the coacting substructure for restricting the rotation of one or more bolts or nuts which are included in the connection.
