Application June 26, 1947, Serial No. 757,283

2 Claims. (01. 129-12) This invention relates to looseleaf post binders. The invention is applicable to binders having the posts thereof disposed at any point longitudinally of the binder base or binder top, and provided with adjustable means whereby sheets having differently spaced perforations, and with different diameters of perforations, may be properly engaged by posts of different diameters which constitute a part of the binder.v

In present-day post binders, the structure is not flexible, and a dealer is required to carry a large inventory in order to accommodate the numerous demands due to the different spacing of posts, as well as the different sizes of the posts and diameters of the perforations of the loose sheets going into post binders. Attempts to provide adjustablepost supportingmeans at the ends and sides of the base member are unsatisfactory, because they weaken the metal base and are not adequate for the sturdy supporting of posts at any point longitudinally of the base member of the binder.

An object of the present invention is to overcome the above difliculty by making it possible further object is to provide an extremely sturdy structure in which a binder base member of relatively light metal is effectively braced for the supporting of posts, while, at the same time, enabling the posts to be located in adjusted posi- A further object is to provide a post binder structure in which the post supporting block is adjustably mounted in the binder base and adapted to be locked therein by rotating the post. Yet

another object is to provide a binder base member of improved structure in which slots are provided for adjustment of the post supports, while, at the same time, providing reinforcements of metal for the hollow base coextensive with the '"at line 4-4 of Fig. 2 Fig. 5, a broken top plan view of a modified form of the invention; Fig. 6, a broken sectional detailed view, the section being taken as indicated at line 6-6 of Fig. 5; Fig. 7, a broken sectional detailed view, the section being taken as indicated at line of Fig.

.5; Fig. 8, abroken top plan view of another modified form. of .binderv embodying my invention;

Fig. 9, a sectional detailed View, the section being taken as indicated at line 9-9 of Fig. 8; and Fig. 10, a broken sectional view, the section being taken as indicated at line |0-l0 of Fig. 8.

In the illustration given in Figs. 1 to 4 inclusive, I] designates a binder basemember, and II The base binder I0 is formed of sheet, metal' to provide a hollow interior, as illustrated best in Figs. 3 and 4. The ends of the base are closed by caps l6, held in position by rivets IT. The specific illustration given shows that the top wall I 8 ofthe base member is provided, at an intermediate point, with a slot I9, and a depending flange 20 extends entirely around the slot. I9. It will be noted that the depending flange 20 not only extends along the sides of the slot l9 but also across the ends of the slot.

Mounted within the chamber of the base I0 is a slidable block 2| tapped to receive the, thread.- ed end 22 of a binder post l2. The block 2| is provided with a channel 23 receiving the depending flanges 20, as shown more clearly in Fig. 4. The flanges 20 thus serve as a guide for the block 2| and also serve to receive the upward thrust of the block 2| when itis drawn upwardly by the rotation of the post l2.

In the operation of the structure shown in Figs. 1, 2 and 4, the posts l2 may be placed in position so as to loosely engage the block 2| and may be moved within the slots l9 to the desired positions for receiving the perforations of the paper sheets l5. If the selected posts l2 are too large for the perforations, smaller posts having, however, threaded extensions 22 of the same diameter, may be substituted. With posts of the desired diameter and located in the desired position for the available sheets I5, the user maynow adjust the posts so as to lock them securely in their adjusted position. The locking operation is accomplished simply by rotating the posts l2 so as to cause them to enter more deeply into the threaded openings of blocks 2|. This causes the blocks 2| to raise and press against the top portion of the base member ID. The frictional engagement produced by the block 2| against the upper portion of the base member I0 serves to anchor rigidly the post,- block and binder just as effectively as if the parts had been originally secured in this permanent relationship. I

Should it be necessary, however, to adjust the verse slot 25.

posts again to sheets having differently spaced perforations, or to-sheets having smaller-or larger perforations, the adjustment can be readily accomplished by unscrewing the posts 92. New

posts having the desired diameter are then placed in position, as already described, and after the posts have been moved with blocks 2! to their new desired position, the posts may be screwed again into the blocks 2| to provide anew rigid support for posts l2. In the longitudinal'movement of the blocks 2 l, the end portions of: flanges 20 serve as stop means for such movement. At the same time, the flanges 20 provide sturdy reinforcement for the metal of the. base It for the full extent of the slot l 9.. Since the flanges run longitudinally of the top wall l8 of thebase binder, they provide beams which prevent bending of the top wall l9 under the clamping action of the post screw and block..

I In thev illustration given in Figsto '7 inclusive, the base member Ills is provided with a slot 24. Reinforcing the slot 24 is a fixedmetal. block 25 welded or otherwise secured to the bottom wall of the member 80 and provided with a trans- The: transverse. slot-25 receives a slidable block 2'! threaded toreceive the threaded end. 28' of the post. l2 The fixed block. 25 is also provided, at its. top, with a longitudinal channel 29- throughwhich. the reduced threaded end 28 of the post 12* extends.

Inthe operation. of the structure shown in Figs. 5 to '7 inclusive, fixed block 25 provides the reinforcement for the weakened portion of the binder produced by cutting the slot 24 therein, and such fixed blockprovid'es the track for the movable block 21.. In other respects, the operation is the same as that heretofore described for the structure inFigs. 1 to 4. inclusive.

In the modificationillustrated. in Figs. 8 to inclusive, the base member [0 is provided with aligned slots 38 and 3!. in its. top and bottom walls respectively. Within the binder base is mounted an elongated. slidabl'e block 3-2. The block 32 is adj-ustably locked in position by means of two

set screws

33 and 34. If desired, a single screw of this type may be employed. The block 32 isprovided with an aperture 35. adapted to receive a post l 2 Means are provided for. supporting the post [2 irrespective of itsdiameter, within'the aperture 35 of block 32. Such. means. comprises a slidable block 35 having a jaw portion 31 adapted .to engage. the post l2 as shown more clearly in Fig. 8. The block. 36 is s idably mounted within a recess 38 provided by the block 32, and

diameter is placed. in position within the opening 35' and the block. 32 moved to the selected position. At this point, block 32 is anchored in position by screwing the

members

33 and 34 into position, as shown in Fig. 10. At the same time, the post 12 is firmly anchored within the block 31 by sliding the block. 36 into tight engagement with the post and then turningscrew' 39 to tight locking position.

In the structure shownin Figs. 8' to 10 inclusive, it will be noted that the post [2 may be of any diameter and that it need not have a threaded end' of a. selected diameter. The slidable block 36 adjustably' engages the post [2 and binds it securely in position.

In each of the illustrations given, the top binder member ll may be of any suitable form or construction. In the illustrations given, the binder top member H has its ends closed in the same way as the base member 10, and it is provided with longitudinal slots 4| for receiving the binder'posts.

With the structures described, it will be noted that the slots in the binder base can be provided at any point longitudinally of the base. For example, if there are three binder posts, one post may be located in thescenter of the base while the other posts are located near the ends. Since the ends and sides of. the'base member are intact, the structure is maintained in a sturdy condition while employing relatively thin sheet metal. Further, in the unloosening, adjusting and binding operations required for the structures in Figs. 1' to 7 inclusive, this entire operation can be brought about through simply rotating the posts, and there is no need to modify or change any portion ofv the binder base walls.

While inv the foregoing specification I have set forth. certain specific structures in great detail for the purpose of illustrating the invention, it will be understood that such details may be varied widely by those" skilled in the art without departing from the spirit of the invention.
