Abstract

512,020. Bookbinding. TRUSSELL, C. D. April 4, 1939, No. 10532. [Class 16] In means for securing wirebound refills within a cover, the leaves, 7, Fig. 2, are held together by spaced rings 9, passing through slots in the leaves and all held together by a single length of wire, and the rings are engaged by hooks 13, Fig. 3, formed on one edge of a channel-shaped casing 10 mounted in a cover 23. The rings can also be engaged by hooks 15, facing in the opposite direction and formed on a slide 17, which is mounted in the casing. When the slide is pushed in, the two sets of hooks overlap, and retain the rings. The slide is held in locking-position by spring catches.
