LOOSE-LEAF BOOK.

Specification of Letters Patent.

Patented Dec. 22, 1908.

Application filed May 3,1907, Serial No. 371,502. Renewed May 21, 1908. Serial No. 434,166.

' Books, of which the following is a specification.

My invention relates to improvements in loose-leaf books, and my objects are first, to provide a device whereby separate leaves may be removed or replaced with convenience and des atch, and second, to provide one with but few parts which may be readily assembled for use or taken apart to repair or replace worn or broken parts.

One of the important features resides in arranging the hook-carryin members of the book 1n such manner that t ley will perform the J function of holding the books either closed or open, hence'separate springsfor performing this function are dispensed with.

In order that the invention may be readily understood reference will now be made to the accompanying drawing, in which:

Figure 1 re resents a'broken end view of my improved cose-leaf book in a closed condition. Fig. 2 is a cross-section of same on the plane of line II-II of Fig. 4, with the vbook in an open condition. Fig. 3 is a perspective of the frame and the' hook-car ing members detached from each other. Flg. 4 is a plan of said parts assembled.

`1 vdesignates thev frame which is slightly convex in cross-section to give the. back of the book a rounded appearance. Said frame is provided with upturned ,ends 2, having vertical slits 3 communicating with curved r horizontal slits 4. All of' said slits render the bearing members 5 of the upturned ends slightly resilient, so that they may spring apart as hereinafter described.

6 designates two hook-carrying members provided at their ends with trunnions 7,

which are rockingly mounted in the bearing Each` members 5 of the upturned ends 2. member 6 has a downwardl curved resilient lip 8, extending about onealf the length of its inner side, see Fi 3. -Said lips are alternately arranged so t at the lip on one mem- 4 ber will underlie the companion member, as

shown in Fig. 2. The straight inner edges 9 of hook-carrying members 6 enga e the upper surface of li s Sand thus hold the engaging edges of sai members either in a depressed or a raised position, so that the members will in turn reliably hold the segmental hooks 10,-

carried thereby, either closed or open.`

The resiliently engaging edges of the hookcarrying members will be assisted in holding the hooks either closed or o en by the resilient bearing members 5 of t e frame, which bearing members will be forced slightly apart during the opening or closing o eration of the hooks, and then spring towar each other at the completion of said operation. l

While it is desirable to have the bearing members 5 resilient, this is by no means essential, as the resilient li s 8 and edges 9 are sufficient to reliably ho d the hooks -either movement of,

open or closed. `The o ening t e hooks 10 is limite by t e downturned outer edges 6a of the hook-carrying members contacting either with the frame or a retaining-plate, hereinafter described.

1 1 designates the cover which is secured to the back 4of the frame by a strip of hair-cloth or other suitable material 12, secured to the frame by a retaining-plate 13, which is secured by screws or rivets 14 to said frame.

Having thus described my invention, what I claim is 1. In a devicel of the character described, a frame, and two hook-carrying members rockingly mounted therein, said members having resilient inner sides engaging each other for the purpose described.

2. In a device ofthe character described, a frame, and two hook-carrying members rockingly mounted therein, each member being provided with a resilient lip yieldingly engaging the other member.

3. In a device of the character described, a frame, twoI resilient hook-carrying members yieldingly enga ing each other, and trunnions on the-en s of said members mounted in the frame.

4. In a device ofthe character described, a frame having upturned ends, and two hookcarrying members rockingly mounted in said ends, said members having ,resilient inner sides engaging each other for the purpose described. Y

5. In a device of the character described, a frame having resilient upturned ends, and two hook carrying members rockingly mounted in said ends, said members having resilient inner sides engaging each other for the purpose described.

6. In a device of the character described, a

frame; and two hook-carrying members rock-` frame, two hook-carrying members rockingly' Y mounted therein, said members having resilient inner sides engaging each other for the purpose described7 a cover at the back of the frame, fabric for securing said coverto the frame, and a retaining-plate for securing said fabric to the frame.

8. In a de vice of'the character described, a frame having resilient upturned ends, and

two hook-carrying members rockingly mounted in said ends, lsaid members having resilient inner sides engaging each other for the purpose described. .l

9. In a device ofthe character described, a frame, and two hook-carrying members rockingly mounted therein, said members having alternately arranged resilient lips engaging their inner sides. l 1

In testimony whereof I 'affix my signature, in the presence of two witnesses.
