LOOSE-LEAF BINDER.

Specification of Letters Patent.

Patented June 30, 13914.

Application filed April 30, 1913. Serial No. 764,708.

1/ b all whom it may concern;

Be it known that I, WILLIAM T. BLAY- LOOK, a citizen of the United States, residing at \Vaynesville, in the county of Haywood and State of North Carolina, have invented certain new and useful Improvements in Loose-Leaf Binders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappci'tains to make and use the same.

This invention relates to loose leaf binders and has for its object to provide a device of this nature which will be simple in construction, eliicient in action and more. con venient in use than those heretofore proposed.

With. these and other objects in view the invention consists in. the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specification in which like numerals designate like parts in all the views Figure 1 is a diagrammatic sectional view of a book provided with my invention; Fig. 2 is a perspective view of my binder detached; Fig. 3 is an end elevation of the parts shown in Fig. 2; and Fig. 4 is a cross sectional view of the parts shown in Fig. 3.

1 indicates a top bar preferably hollowed out and curved on the outside as shown, 2 a similar bottom bar, 3 and 4: end pieces rigid with said bottom bar, and 5 and 6 similar end pieces rigid with said top bar. The

end pieces

3 and 5, and 4t and 6 are adapted to telescope or slide past each other as illustrated, and the

said pieces

5 and 6 are preferably provided with the

perforations

7 and 8 respectively. The

end pieces

3 and 4 are provided with the spring members 10 and 11 respectively, which in turn carry the pins 12 is provided with a slot 1 1 into which works the pin 12, and the end piece 4 is provided with a slot 15 into which works the pin 13. The bottom bar 2 is further provided with spaced leaf holding pins or members 16, while the top bar 1 is provided with similar spaced leaf holding pins or members 17, said

pins

16 and 17 being in staggered relation to each other as shown, and being of such a length that the one set 16 will still overlap the other set 17 when the members 1 and 2 are separated to the maximum extent permitted by the

holes

7 and 8.

20 represents a covering of leather or other material secured to the members 1 and 2, and to which may be secured the book covers 21 and 22 if desired. The rear portion 24 of the member 20 may be left full as shown, if desired, in order to facilitate the wide and ready separation of the members 1 and 2.

The operation of my loose leaf binder is as follows :The leaves 25 are perforated with as many holes as there are

members

16 and 17 and said holes are spaced apartthe same as on said members. The members 1 and 2 being su'liiciently separated the one from the other the leaves 25 are readily strung on the said members 16, whereupon the members 17 are next brought down and threaded into. the remaining holes, and the members 1 and 2 caused to firmly bind on the top and bottom leaf as illustrated. When in this position the

pins

12 and 13 are caused to engage

appropriate holes

7 and 8 respectively and their corresponding springs 10 and 11 securely hold the said members 1 and 2 in place.

When it is desired to open the binder to add or take out a leaf, the springs 10 and 11 are pulled back to disengage the

pins

12 and 13 from their holes, and said springs are swung on their pivots 26, so that the said pins will occupy the

slots

14 and 15, as inclicated in dotted lines in Fig. 8. When inthis position the end members 5 and G can be readily slid past the

end members

3 and 4 without the annoyance of the

pins

12 and 13 catching in their holes, and leaves may be added or subtracted with great facility. Further the pin members 16 being sufiiciently long to accommodate all the leaves the binder is designed to receive, they hold the said leaves in position at all times for an easy manipulation.

When the leaves are securely in place, as shown in Fig. 1, the curved exteriors of the members 1 and 2 greatly facilitate the folding back of said leaves, which further enables one to open wide the book without having to strain any of its parts. In addition, these curved surfaces afiord an easy rest for a heavy book on a desk and greatly facilitates its convenient handling. For large books the spring 10 is made quite stiff, and in some instances I provide a key lock to prevent unauthorized tampering.

It is obvious that those skilled in the art may vary the details of construction as well as the arrangement of parts without departing from the spirit of my invention and therefore I do not wish to be limited to the above disclosure except as may be required by the claims.

That I claim is 1. In a loose leaf'binder the combination of top and bottom members provided with coacting adjustable end members, curved in cross section and fitting the one into the other; detachable engaging means for securing said end members in their adjusted positions, said means provided with a pivot to enable the same to be swung to one side and thereby avoid interfering with the adjustment of said end members; and a plurality of staggered leaf holding members associated with said top and bottom members substantially as described.

2. In a loose leaf binder the combination of top and bottom members having curved outer surfaces and provided with coacting and adjustable end members curved in cross section and slidingly fitting each other; detachable spring engaging means for securing said end'members in their adjusted positions provided with a pivot to permit said means to swing to one side and avoid interference with the adjustment of said end members; and leaf holding members in staggered relation to each other rigid with said top and bottom members, substantially as described.

3. In a loose leaf binder the combination of top and bottom members each comprising a straight body portion and end portions eX- tending at right angles to said body portion said body portions having outwardly curved surfaces to facilitate the opening and the folding back of the bound leaves and the end portions slidingly fittingeach other and provided with registering holes; a spring con trolled pin for entering said holes and firmly holding said side and end portions in their adjusted positions; a pivot on which said spring and pin is mounted whereby said pin may be removed from said holes and swung to one side and thereby prevented frominterfering with the adjustment of said end members; and staggered leaf holding mem bers carried by said top and bottom members, substantially as described. a

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