ARTHUR R. MEYER AND ELMER A. REED, OF CHICAGO, ILLINOIS, ASSIGNORS TO WILSON-JONES LOOSE LEAF COMPANY, A CORPORATION OF ILLINOIS.

snrrrrrnemosr BINDER.

To all whom it may concern:

Be it known that we, ARTHUR R. MEYER and ELMER A. REED, citizens of the United States, and residents of the city of Chicago, in the county of Cook and State'of Illinois,

have invented certain new and useful Improvements in a Shifting-Post Binder; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings and to the numerals of reference marked thereon.

This invention relates to loose leaf bind ers having telescoping or relatively slidable 1 posts upon which the leaves are removably hinged by means of apertures or notches in the leaves. c

It is an object of this invention to pro vide a binder of this type with longitudinally shiftable means in combination wit-h leaves having slots, whereby the leaves can be locked in the binder in one position of said means and unlocked therefrom in another position thereof.

It is a further object of this invention to provide a structure in which the leaves can be readily offset with relation toeaeh other. lVith these and other objects in View. which will become more apparent in the following description and disclosures in the drawings, our invention comprises the novel features of construction hereinafter described and more particularly pointed out in the appended claims.

In. the accompanying drawings which illustrate a preferred embodiment of our in vention, and in which similar reference numerals refer to similar parts in the different views: a H

Figure 1 is a front plan view of a binder with the hinged covers removed embodying the features of our invention. Figure 2 is a side elevationthereof showing how the post supports are slidably supported on the side walls'of the binder.

Figure 3 is'a section on the line 33- of Figure 1 on an enlarged scale.

Figure 4C is a longitudinal section through the binder on the line 4t of Figure 3.

Figure 5 is a front perspective view of the binder involving our invention containing leaves which are separated in the center and folded over to illustrate a simple means for shifting the posts.

Figure 7 with parts omitted.

Figure 7 is a section similar to Figure 3 illustrating the means for shifting the posts on an enlargedscale. t

Figure 8 is a diagrammatic view of the slotted rear'portion of a leaf illustrating the locking and unlocking position of the posts.

As shown on the drawings: For the purpose of illustrating and explaining the operation of our invention, we have shown the same incorporated in a binder which, for this purpose may be any binder that contemplates the useof leafholding means or posts or. the like, for removably retaining the leaves. The illustrated form of binder comprises briefly a back or base 1 upon which are slidingly supported the curved or beaded side walls 2 having the horizontal flanges 3 which rest and slide transversely on the base 1 and the vertical portions 4 for supporting the posts, and theintermediate curved or beaded portions in which the studs 5 are mounted.

Figure 6is a section on the line 6-6 of These studs are connected to links 6 which are operatively connected by meansof nuts 7 to the screw member 8 anchored to the base. The screw member may be operated for adjusting the sides of the binder as is well known in the art. I

Our invention as applied to the above described binder or incorporated therein consists of shif'table' leaf-holding means adapted to cooperatewith slots in the loose leaves for looking or unlocking them with respect to the binder, and means for shifting the leaf-holding means. lVhile the leaf holding means may take various forms, in the present instance, a plurality of pairs of telescoping posts 9 and 10 are shown which are secured to slidable plates or members 11 adjustably supported on the inner sides of the walls 2 by means of headed projections 12 extending through slots 13 in'the side walls 2 and secured in'said plate members 11 with the headsonthe projections overlapping the slots on the outer surface of the side wall. members 11 may be used, and each pairv comprising a plate member on one side wall,

and the plate member directly opposite 011 the other side wall may support one or more pairs of posts as desired. A preferable con- Any even number of .slidable I struction, the one which we have illustrated,

contemplates the use of two pairs of slidable regarded merely as a matter of design.

This invention contemplates the use of loose leaves having slots which the posts can enter and in which they can be shifted for locking purposes. Thus slots having entrance necks and each having a longitudinally extending notch of sufficient depth would answer for this purpose, but we preferably desire to useleaves with slots having entrance necks with each slot having two oppositely extending longitudinal notches of suitable depth producing a slot known as the mushroom or T-shaped slot as shown in Figure 8. It should, however, be understood that by the term slot is meant any form of slot that allows the posts to slightly shift therein to engage the walls thereof for holding purposes.

From an inspection of the slotted leaf 14 shown in Figure 8, it will be seen that certain posts are shifted in one direction to the ends of the mushroom slots as shown in dotted lines and that other posts are shifted in the opposite direction to the opposite ends of the slots as shown in dotted lines, thus securely locking the leaves from being longitudinally movable and also from being transversely movable or removable from the binder when the said posts are in leaflocking position. The longitudinal shifting movements of the posts or leaf-holding means should be limited so that said posts cannot be shifted beyond the ends of the slots to crimp or spoil the leaves when moved to locking position and cannot be shifted beyond the entrance neck of the slot when shifted to unlocking position so that leaves can be readily inserted or removed. To thus limit the movement of said posts, the slots 13 in the side walls 2 are made of a length of a desired proportion as com pared to the length of the mushroom slots determined by the movement from full line to dotted line position in Figure 8 so that the plate members 11 which are supported in said slots and which in turn support said posts can only be adjusted or shifted the proper distance- In order to lock the leaves in the binder, the upper pairs of posts shown in the binder and which are supported by a pair of said plate members 11 can be simultaneously moved downwardly from the full line posi tion to the dotted position (Figure 8), and the lower two pair of posts which are similarly supported can be simultaneously moved upwardly from full line to dotted line position. The shifting operation can be effected by hand or some means may be provided. A simple means for this purpose is illustrated in Figures 5 and 6 and consists of a pair of thin plate members 15 having deep notches 16 in their lower edges to receive the posts, one plate member being designed to fit over the upper pair. of posts while the other is adapted to fit over the lower pair of posts. Both plate members are designed to project a short distance beyond the ends of the binder whereby they may be grasped by the hand for shifting purposes. These members 15 can readily be inserted between the loose leaves and when inserted in the same place as between the same leaves, it is necessary that their inner ends be spaced apart a distance equal to at least the length ofthe shifting movements of both plates. For this purpose, the members 15 are so designed that suflicient spacing between the inner ends is alwaysprovided.

For the purpose of permitting the leaves of the binder to be offset,.the leaf-holding means or posts are equally spaced so that when the posts are in a leaf-unlocking position, as shown in full lines in Figure 8, a leaf can readily be removed and shifted beyond the ends of the binder a distance equal to the distance between two posts. The

leaf may then be inserted again and retained by the remaining posts or one post less than the number of posts used as is obvious from Figure 8, or in other words the leaf is offset with respect to one of the outer or end posts. This binder is accordingly well. adapted for either pen and ink. or mechanical bookkeepmg.

In using a binder involving theabove dedescribed invention, leaves can readily be inserted or removed by shifting the posts to leaf-unlocking position. I l Vhen no special shifting means are provided, the shifting of the posts can be done by hand. Vhen the shiftable plate members 15 are used, the outer ends thereof can be grasped by the fingers and the plates shifted to bring the posts to leaf-unlocking position as is obvious. In the illustrated invention, the

posts move inwardly of the binder when they are shifted to leaf-locking position, and move outwardly to leaf-unlocking position, but it is obvious that a reverse arrangement could be adopted.

We are aware that numerous details of construction can bevaried through a'wide range without departing from the principles of this invention, and we therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

We claim as our invention:

1. In a loose leaf binder having side walls provided with, slots, a, plurality of plate members having headed projections slidable in said slots, and leaf-holding posts carried by said members.

2. In a loose leaf binder, th combination with a plurality of equally spaced longitudinally shiftable leaf-holding means, of leaves having slots for engaging said means to be locked in the binder thereby, said means being shiftable to leaf-unlocking position in said slots, whereby a leaf may be removed and offset with respect to one of said leafholding means.

3. In a loose leaf binder the combination with longitudinally shiftable leaf-holding insertable between said leaves for engaging said posts for shifting the same into and out of the notches in the leaves.

In testimony whereof we have hereunto subscribed our names in the presence of two subscribing witnesses.
