Abstract

Abstract A two part molded plastic reel wherein the parts are alike, and each part comprises a flange and a part of the spool, said spool parts being axially telescoped together to complete the reel. Each spool part has an exterior semi-flexible tooth member thereon which engages with a complementary inner fixed tooth member on the other part, so that the two spool parts when shoved together form a complete double wall spool which cannot be separated thereafter.

Claim 1
Independent Claim 114 words
A reel comprising two like parts, each part comprising a flange and a partial spool thereon, each partial spool comprising a semi-cylindrical portion of a predetermined radius, and another semi-cylindrical portion of lesser radius, a springy longitudinal tongue forming a part of one of the semi-cylindrical portions, interengaging means on the tongue on the outside aspect thereof, and complementary interengaging means on the other of said semi-cylindrical portions at the inside aspect thereof, said interengaging means forming a snap-over connection upon longitudinal motion inwardly together of said spool portions to a point where the free ends of each semi-cylindrical portion approaches the inside aspect of the flange on the other of said semicylindrical portions.
Claim 2
Dependent Claim 114 words
A reel comprising two like parts, each part comprising a flange and a partial spool thereon, each partial spool comprising a semi-cylindrical portion of a predetermined radius, and another semi-cylindrical portion of lesser radius, a springy longitudinal tongue forming a part of one of the semi-cylindrical portions, interengaging means on the tongue on the outside aspect thereof, and complementary interengaging means on the other of said semi-cylindrical portions at the inside aspect thereof, said interengaging means forming a snap-over connection upon longitudinal motion inwardly together of said spool portions to a point where the free ends of each semi-cylindrical portion approaches the inside aspect of the flange on the other of said semicylindrical portions.
