i fai i T LOOSE-LEAF BINDER.

Application filed December 14, 1922. Serial No. 606,828.

To all whom t may concern:

Be it known that ll, CHARLES R. HADLnr, a citizen of the United States, residing at 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.

This invention relates to a loose leaf binder of the type employing means to engage notches in the edges of the loose leaves for the purpose of holding said leaves against shifting in the binder. The invention relates more particularly to that type of binder employed in machine book-keeping; in other words to binders in which any of the leaves may be offset from the remainder to denote that the accounts on said offset leaves have been posted, or for any other purpose.

An object of the invention is tor provide for locking the oset leaves in offset position.

Another object is to accomplish the foregoing by a comparatively simple construction.

The accompanying drawings illustrate the invention:

Figure 1 is a perspective view of a binder constructed in accordance with the provisions of this invention, some of the leaves being shown offset from the remainder.

Fig. 2 is a perspective view of one of the binder leaves.

Fig. 3 is an enlarged sectional elevation on the line indicated by 33, Figure 1.

Fig. 4 is an enlarged broken plan view, partly in section, from the line indicated by 4 4, Figure 3.

Fig. 5 is a sectional elevation on the irregular line indicated by 5 5, Figure 4.

Fig. 6 is a sectional elevation on the line indicated by 6--6, Figure 4.

The covers of the binders are indicated in the drawings at 11, 12, respectively. Said covers, if desired, may be formed of hingedly connected sections, the hinges being indicated at 13 and not being illustrated in detail, since such construction is old in this art. The binding strips of the. covers 11, 12 are indicated at 14, 15, respectively and they serve to clamp the loose leaves 16 between their adjacent faces. The binding strips 14, 15 may be releasably held in leaf-clamping position by any suitable means, as, for example, the movably mounted posts 17, 18. The post 17 is pivoted as indicated at 19. The construction of the post 17 is well understood in this art, the same having been the subject-matter of Letters Patent No. 1,301,085, granted to me April 15, 1919, and it is to be understood that any other suitable clamping means may be substituted for the post 17.

The pivot of the post 18 is indicated at 2() and on said post is a nut 21 adapted to bear upon the upper face of the binding strip 15 when the post is in clamping position within a slot 22 in the end of the clamping strip 15. The lower end of the post 18 constitutes an eccentric or cam 23 adapted to bear against one end of a longitudinally shiftable member 24 which is mounted in a slot or way 25 foi-med in a block 26 that constitutes a portion ofthe binding strip 14. The block 26 is provided at one end with a head 27 which supports the pivot 20. The member 24 is yieldingly held in engagement with the eccentric 23 by a coil spring or springs 28. One end of each spring 28 seats in a socket 29 in the member 24 and the other end of each of said springs seats in a socket 30 in the block 26.

Screw-threaded at 31, or otherwise mounted on the member 24, are leaf-engaging means, in this instance comprising a post 32 which projects through a slot 33 in the binder strip 14 and through a slot 34 in the binder strip 15. When the post 18 is swung to open position, as in Figures 4 and 5, the post 32 is moved to the right by reason of expansion of the springs 28, and when the post 18 is moved from the open position to the closed position shown in Figure 3, said post 32 is moved to the left, compressing said springs.

The binder leaves 16 are each provided in their longitudinal margins with straight notches 35 and with angular or L-shaped notches 36, it being understood that one notch 36 in each leaf is sufficient and that the two are provided so that the leaves can be reversed in the binder, if desired. The leaves 16 are also provided in their end margins with notches 37. When the leaf is in. position in the binder with one of the notches 37 engaging the post 17 the other notch 37 will be in position to be engaged 'by the post 32 when the post 18 is in closed position, as in Figure 3. rihe leaf thus locked will be held against edgewise movement in any direction, thus preventing it from slipping out of place. When it is desired to shift the leaf to the offset position, the post 18 will be in the open position shown in Figures a and 5, the notch 37 that previously was 4engaged by the post 32 will be engaged by the post 18, and one of the angular notches 36 will then be engaged by the post 32.

To lock the leaf in the offset position, the post 18 will be closed, thus moving the post 32 into the offset or longitudinally extending portion 38 of the notch 36, said offset portion being alined with the notches 37. It will be clear that the notches 35 engage a stationary post 39 which is mounted in the binding strip 14 and projects through a hole 40 in the binding strip 15. The post 39 is positioned midway between the posts 17, 18, and the notches 35, 36 are placed at equidistant intervals so that the appropriate notches will properly engage the posts 39, 32, whether the leaves be in position to engage the posts 17, 32 or be odset so as to engage the post 18. The operation of the binder will be understood from the foregoing description, since, in order to remove the cover 13, it is only necessary to swing the posts 17, 18 into open position.

I claim:

1. In a loose leaf binder, the combination of covers, means to clamp the covers upon loose leaves therebetween, means adapted to engage in notches in the leaves, and means operatable byV movement of a portion of the clamping means to effect movement of the notch-engaging means.

2. In a loose leaf binder, the combination of covers, movable clamping means adjacent one edge of the covers to clamp the covers upon loose leaves therebetween, means adapted to engage in notches in the leaves, and

means operatable by said clamping means to effect movement of the notch-engaging IIIGLBS.

3. In a loose leaf binder, the combination of covers, means operable to engage and prevent edgewise movement Vof loose leaves placed between the covers, and means movably mounted on one of the covers operatable to move the leaf-engaging means to and from leaf-engaging position.

4. In a loose leaf binder, the combination of covers, means operable to engage and prevent edgewise movement of loose leaves placed between the covers, and means movably mounted on one of the covers operatable to clamp the covers upon the leaves and to move the leaf-engaging means to and from leaf-engaging position.

5. In a loose leaf binder, the combination of covers, a member shiftable into positions toengage and disengage notches in the longitudinal margins of leaves placed between the covers, and means to shift said member into the different positions.

6. In a loose leaf binder, the combination of covers, and a member shiftable into positions to engage and disengage the longitudinally extending portion of L-shaped notches in the longitudinal margins of leaves placed between the covers.

7 In a loose leaf binder, the combination of covers, a member shiftable into positions to engage and disengage the longitudinally extending portion o'f L-shaped notches in the longitudinal margins of leaves placed betweenthe covers, and means to shift said member into the different positions.

Signed at Los Angeles, California, this 7th day of December, 1922.

CHARLES R. HADLEY.
