Application filed May 21, 1910. Serial No. 562,706.

To all whom it may concern:

Be it known that l, (JiUS 1AV l Mnwns, a citizen of the United States of America, residing in the city of St. Louis and b'tatc of Missouri, have invented certain new and useful improvements in Loose-Leaf Books, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to loose leaf books and, briefly stated, the invention consists in 4. c a spring or resilient post or book leaf holding member that provides for the leaves of the book being held in their normal positions when the book is closed and is capable of flexing outwardly when the book is opened, in orderth'at the leaves of the book may lie in approximately llat positions above the covers due to the flexing of the leaf holding members.

Figure I is a perspective view of a frag- -ment of a loose leaf book having my improvement therein. Fig. II-is an end view of the back portion of the book with the leaves of the book partlybroken out to afford a view of one of the resilient leaf holding members. Fig. H1 is an end view of the rear portion of the book. Fig. 1V is a perspective view of the back of the book,

fragments of the bookcovers, and the means by which the resilient leaf holding members are confined in the book, one of the leaf holding members being shown in dotted lines. Fig. V is,a perspective view of one of my loose leaf holding members.

In the accompanyingdrawings :-A desig nates the back of a loose leaf book and B the covers hinged to said back.

C are, tubular rod receiving members suitably attached to the back or covers of the book and which receive rods D adapted to be introduced into and withdrawn from the members (I), therods being eaclr provided at one end with a linger-piece E. The rod receiving members 0 are spaceda part to p'rw vide gaps for the reception of leaf receiving members, the ends of which are held In position in said gaps by the passage of the rods I) thercthrough.

The parts thus far described are known to be old, and no inventionpcr so is herein claimed for them.

My leaf receiving members lltlllpitll to be held in the loose leaf book through the .gle strip 1, having medium of the members 0 and D are made of single pieces of resilient or spring ma-' terial, such; as steel. lnthe drawings, the leaf receiving members each comprise a sintwo bends .2 and 3 therein, located intermediate of the ends of the strip and from which bends the strip extends in the form of tongues eand 5 that overlap each otheigas seen .lllOSl) clearly in Figs. ll and V. The back of each leaf receiving member, which constitutes the main body of the member, is bowed forwardly from its center tothe bends 2 and3 and the tongues t and 5 extend rcarwardly from the tongues 2 and toward the back of said member, and the parts of the leaf receiving members just referred to always retain the form mentioned when the book in which they are utilized is in a closed condition.

When, however, the book is opened, the leaves act against the leaf receiving 'mem bers that'extend therethrough as seen in the drawings and are held by the passageofthe rods D therethrough. lhe result 'of the pressure of the leaves against the leaf receivingmembers .is that of causing the leaf receiving members to i be flexed upwardly =01 outwardly relative to the back of the. binder, as seen in Fig. ill, so thatt-he book leaves will open out more flatly than they Would in the use of rigid leaf rcccivingmembers.

It will be-readily appreciated that the resiliency of the leaf receiving members is made possible duetothetongues 4 and5 of these members overlapping each that when the books of the members areto partake of flexing action, ride against each other to permit straightening of the backs of the members and revcrsal of the bowed conditionof said .memhers.

1. In a loose leaf book, a cover, members for the attachment of a leaf receiving device carried by said cover, and adouble bowshaped resilient leaf receiving device fitted other, so

the tongues will to said'lirst named members; said leaf receiving devices comprising an unbroken portion and tongues opposite the unbroken portion loosely overlapping each other.

2. In a looselcat book, a cover, members for the attachment of a leaf receiving de vice carried by said cover, and a how-shaped resilient leaf receiving device titted to said first named members; said leaf receiving device comprising a back portion and front tongues loosely overlapping each other.

3. In a loose leaf book, a cover, members forthe attachment of a leaf receiving device carried by said cover, and a bowshaped resilient leaf receiving device fitted to said first named members; said leaf receiving device comprising a strip of material bent intermediate of its ends to pro- GUSTAV F.
