DEFINITION

Classification: 242/570

COIL HOLDER OR SUPPORT (E.G., SPINDLE, DISPENSER, OR SPOOL):

(under the class definition) Apparatus or method wherein particular significance is attributed to structure for supporting a coil of elongated material, which structure may

include: (a) a permanent component of a winding, unwinding or reeling device about which running material is adapted to be wound or unwound, (b) an article of manufacture for temporarily carrying a coil of elongated material, or (c) a mounting structure carrying a spindle, spool, or coil.

(1) Note. Subject matter proper for this subclass includes a coil holder: (a) usable as a permanent or semipermanent component of a winding or unwinding machine (e.g., an expansible mandrel, spindle, or arbor), (b) usable as a permanent part of a reeling device (e.g., tape recorder, reel, winch, etc.), (c) combined with a mounting structure (e.g., dispenser, winding machine subcombination) or (d) an article of manufacture (e.g., spool, bobbin, core, card, etc.) on which an elongated material is directly wound.

(2) Note. Subject matter proper for original placement in this subclass must be at least disclosed as: (a) being progressively wound rather than repetitively fed as in the case of a drive belt pulley, capstan, or other motion transmission or conversion mechanism, (b) having utility for storing coiled material on its structure for more than 360 deg. distinct from a banded member (e.g., a labeled can), (c) storing the elongated material, albeit shortly, distinct from being permanently coiled as a permanent part of a wound article, such as a ball, inductance device, etc., and (d) having the capability of being removed in the same general physical form as prior to coiling, which precludes bending a material beyond its elastic limit to form shaped coils.

(3) Note. The claiming of structure either as a component or whole electrical article (e.g., a terminal pin, pole piece, inductance, resistance, etc.) is provided for in the appropriate electrical article class.
