Abstract

486,535. Spools. STANDARD TELEPHONES & CABLES, Ltd., and TURNER, F. B. Dec. 4, 1936, No. 33314. [Class 120 (iii)] A coil-supporting spool of rectangular cross-section is made up of four pieces of insulating material two of which A, C are cut along the edges so that the other two B, D key into them to form a self-supporting structure. The pieces B, D may have projections H at their ends for holding in position the end cheeks S.
