LOOSE-LEAF BINDER.

Specification of Letters Patent. Patented Apr, 15, 1919,

Application filed November 6, 1916. Serial No..129,642.

To all whom it may concern:

Be it known that I, CHARLES R. HADLEY, a citizen of the United States, residing in Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Loose-Leaf Binder, of which the following is a specification.

An object of this invention is to facilitate the removal and replacement of the leaves of a binder.

Another object is to produce a device of this character of maximum simplicity of construction and operation.

Another object is to-make provision for loosening all of the leaves simultaneously so that all or any one of them can be quickly removed, or another leaf inserted wherever desired.

Other objects and advantages will appear in the subjoined detail description.

The accompanying drawings illustrate the invention Figure 1 is a perspective view of the binder withthe parts in closed position.

Fig. 2 is a perspective view of the binder showing one of the covers and" one of the leaves detached.

Fig. 3 is an enlarged detail of the fastening device.

Fig. 4 is an'enlarged detail of a modified form of the fastening device.

Fig. 5 is a perspective view of the'nut and clamp shown in Fig. 4.

Fig. 6 is a plan section on line indicated by m, m, Figs. 3 and 4.

There are provided two covers, one of said covers comprising a binding strip 1 and a cover member 2 hinged at 3 to said binding strip; and the other cover comprising a binding strip 4 and a cover member 5 hinged at 6 to the binding strip 4. Relatively loose leaves 7 are provided between the cover members 2, 5 and said leaves also extend be tween the binding strips 1, 4.

The strips 1, 4 are provided with notches 8, 9, respectively, said notches in the instance, shown being in the ends of said binding strips. In the notches 9 are hinged or 10 links or posts 11, and said posts may be sectional if desired, as iswell understood in the art, so that the binder may be made of any desired capacity .by changing the number of sections.

The binding strips 1, 4 may be of any suitable construction, and in the instance shown in the drawings said binding strips may comprise rectangular tubes 12, 13, the tube 12 being provided at its opposite ends with plugs 14 and the tube 13 being provided at its opposite ends with plugs 15. The tubes 12, 13 and the plugs 14, 15 are notched or slotted to form the slots 8, 9 previously described.

The posts 11 are provided on their free end portions with nuts 16, and the walls of the slots 8 may, if desired, be provided with sockets 17 having therein pins 18 and coil springs 19 tending to hold the pins outward in the paths of travel of the posts when said links areswung on their pivots 10. 'Iilb pins 18 yieldingly hold the ports 11 in closed position as in Figs. 1 and 3 and thus constitute latches for said posts.

In the modification shown in Figs. 4 and 5 additional clam-ping means are shown and in this form the nut 16 is pivoted at 20 to eccentrics 21 having a U-shaped operating arm 22, only one of the pivots 20 showing from the nature of the view. When the operating arm 22 is turned as in Fig. 4, the eccentrics 21 exert no pressure against the binding strip 1, but when the arm 22 is turned to the dotted line position a in Fig. 4 the eccentrics engage and ress down upon the binding strip 1 so as to tightly clamp the leaves 7 between the binding strips 1, 4.

It is not absolutely necessary, but in some instances it may be desirable to provide the leaves 7 with notches 23 to register with the notches 8, 9 when the leaves are in assembled position, and when so assembled, with the posts 11 in closed position as in Figs. 1 and 3, said posts 11 snugly fit said notches 23. It is understood that, if desired, the notches 23 may be omitted and the clamping action of the posts 11 and nuts 16 or eccentrics 21 alone relied upon for holding the binding strips 1, 4 toward one another to clamp the leaves 7 in place.

This device is intended to be used in place of other previously invented loose leaf binders and from the foregoing it is clear that in practice, assuming that the parts of the binder are in the positions shown in Fig. 1, if it be desired to detach or insert one or more leaves 7, the nuts 16 will be loosened and the posts 11 will be swung intothe positions shown in Fig. 2 so as to release the binding strip 1, whereupon the cover memher 2 will be removed. Then any one or all ers as before, said leaf or leaves will be placed with their edges flush with one another, and, in case said leaves are provided with notches 23, said notches will be placed in alinement with one another and in alinement with the notches 8, 9, and the hereinbefore described operations will then be carried out in reverse order to put the parts in the positions shown in Fig. 1, thus securely clamping the leaves in place between the covers.

When the eccentrics 2-1 are employed as hereinbefore described the clamping power is materially increased.

I claim:

1. A loose leaf binder comprising covers having notches, posts pivoted in the notches of one cover and adapted to project through the notches of the other cover, nuts on the projecting ends of the posts, and eccentrics pivoted to the nuts to engage said other cover.

2. In combination, binding strips compris ing tubes and plugs in the ends of the tubes having notches, cover members hinged to the binding strips, posts hinged in the notches of one binding strip and adapted to extend through the notches of the other binding strip, and means on the posts to engage the outer face of the last named binding strip.

3. In combination, binding strips having notches in their ends, cover members hinged to the binding strips, posts hinged in the notches of one binding strip and adapted to project through the notches of the other binding strip to the outer face thereof, nuts on the projecting ends of the posts to engage the outer face of the last named binding strip, and leaves between the covers having notches alined with the notches of the covers, the notches of the binding strips and leaves closely fitting the posts, and said nuts and posts being the sole fastening for the covers and leaves.

I. In combination, binding strips having notches in their ends, cover members hinged to the binding strips, posts formed in sections and hinged in the notches of one binding strip and adapted to project through the notches of the other binding strip to the outer face thereof, nuts on the projecting ends of the posts to engage the outer face of the last named binding strip, and leaves between the covers having notches alined with the notches of the covers, the notches of the binding strips and leaves closely fitting the posts, and said nuts and posts being the sole fastenings for the covers and leaves.

5. In combination, covers, leaves between the covers having notches in their opposite edges, posts hinged to and projecting from one cover and engageable with the notches to hold the leaves in place, said posts being the sole means for preventing edgewise movement of the leaves, said notches closely fitting the posts, and means to hold the posts and covers against relative movement. Signed at Los Angeles, California, this 26th day. of October, 1916.
