LOOSE-LEAF BINDER Application filed August 19, 1925. Serial No. 51,109.

My invention comprehends a novel construction and arrangement of a loose leaf binder which consists of but three parts, namely: a fixed part adapted to be connected to a cover, a filler carrying member movably connected with said fixed part, and a slide which is adapted to lock the filler carrying member with respect to said fixed art.

Each of these parts are formed from an integral piece of material, so that the device can be very economically manufactured.

It further comprehends a novel construction of a fixed member, a novel construction of a slide and a novel construction of a filler carrying member.

Other novel features of construction and advantage will hereinafter more clearly appear in the detailed description and the appended claim.

For the purpose of illustrating the invention, I have shown in the accompanying drawing a typical embodiment of it, which, in practice will give reliable and satisfactory results. It is, however, to be understood that ical only and that the various instrumentalities of which my in vention consists can be variously arranged and organized, and that the invention is not limited to the precise arrangement and organization of these instrumentalities as herein set forth.

Referring to the drawings:

1 designates the base member of a loose leaf binder, embodying my invention, and 2 designates a filler carrying member which is hinged to the fixed member in a novel manner and interlocks therewith by means of a slide 3. The binder is adapted to be con nected to a cover 4. The 'fixed member, the movable member and the slide are each preferably formed from a single piece of material. The fixed member is formed from sheet material which is folded to form a rectangular tube with a to 5 and the bottom 6, connected by the si e 7 The top 5 is provided with the slots 8 which are enlarged as at 9, see Figure 3. The top is alsoprovided with the openings 10. The top is deflected downwardly as at 11, see Figure 5,

and it merges into the intermediate portion 12, so that a space is formed between the top 5 and the intermediate portion 12 to receive the slide 3, which is also formed of a single piece of sheet material which is deflected upon itself to form the top member 13 and the bottom member 14.

It will be understood from the foregoing that the fixed member is substantially rectangular in cross section, with the free edges 12 and 6 overlapping.

At one end the slide is deflected as at 15 to form a grasping handle, and the slide in proximity to its end 'is apertured, as at 16, and it is provided with bayonet types of slots 17 which are preferably of the same contour as the slots 8 in the top 5 of the fixed member.

The ends of the fixed member 5 are bent downwardly and inwardly and have the terminals 18 which pass through the cover 4 and the bottomportion 6 ofthe fixed member 5 in order to secure the binder to, the cover. The purpose of the openings 16 in the slide and the registering openings 19v in the fixed member 5 is to enable one to insert a tool through such openings to clinch the ends 18 of the fixed member 5, see Figure 4.

The filler carrying member 2 is formed from a single piece of material and as illustrated, it is bent upon itself to form the filler retaining loops 20, and it is also defiected upon itself to form the hooks 21, which may be located at any desired point in the longitudinal length of the filler carrying member 2, and, as illustrated, each loop has in proximity to it one of the hooks 21 Instead of forming the hook 21 from the longitudinal stretch of the filler carrying member, a filler carrying member 22 may be employed in which the loop 23 terminatesin a horizontally extending hook 24, which, as seen in Figure 11, is locked and unlocked by the slide 3, and the openings 25 which correspond to the openings 8 and 9 are located in the opposite side of the casing from that seen in Figure 7 In the operation, when the slide 3 is moved outwardly, it will be apparent that the hooks 21 will be brought into register with the enlarged portion 9 of the openings 8 and with the enlarged portion of the openings of the slots 17, so that the filler carrying member can be swung backwardly and the leaves of the filler inserted or removed as may be desired.

The operation of the filler carrying member seen in Figures 10 and 11 is similar to that already described, since when the slide is moved outwardly the hooks 24 will be unlocked and when said slide is moved inwardly the hooks 24 will be locked.

The fixed member or casing can be very cheaply manufactured from sheet material, and, at one end, the top is bent downwardly to form the means for securing it to the cover, and, at the opposite end, one of the ferent openings of the slots in the slide and I the casing can be formed at the same time the blank is cut from sheet material.

It will now be apparent that I have de-' vised a new and useful loose leaf binder which embodies the featuresof advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment there-v A loose leaf binder, comprising a base member folded to form a rectangular tube,

a fill'er carrying member hinged to said base member, provided with filler retaining loops and with a hook, and a slide in said tubular Y member cooperating with said hook to secure said loops in their locked or unlocked position, said base having deflected ortions to secure it to its cover, and said use and slide having registering openings to receive a tool to clinch the ends ofsuch portions.

bottom laterally extending portions is bent downwardly to form the means at such end for securing the fixed member to the cover.

The slide is formed from a single piece of material which is transversely folded upon itself, the bottom being of less width than the top. The slide is contained within the fixed member so that when the parts are assembled the longitudinal stretch of the filler carrying member will be retained in hinged relationship with respect to the fixed member or casing which carries it.

It will be apparent that since each of the three parts are formed from a single piece of material that my present construction of loose leaf binder can be economically manufactured, and, at the same time, it will be durable and reliable in practice. The dif-
