Abstract
135,604. Willcocks, F. E. Nov. 28, 1918. Post and like files.-Loose leaves and cards of loose-leaf books, date indicators, writing-pads, &c. are secured together bv means of divided metal or other rings made of flat strip or tube of uniform cross-section throughout, the meeting ends being flush inside and outside the ring and so shaped and arranged that the leaf or card can only pass through the division when bent at a corresponding angle. The division may be a diagonal slit 8, Fig. 2, an arcuate slit 13, Fig. 6, or a zigzag slit 15, Fig. 8. The ends may meet flush, in which case the ring is made of springy material.
