LOOSE-LEAF BINDER.

Specification of Letters Patent.

Patented May as, '1912.

Application filed November 23, 1911. Serial No. 661,914.

plicable to a large variety of books, vary-v ing greatly in size and use. Books of this character consist of a cover or binder and a sheaf or packet of leaves provided with perforations or slits which are engaged by retaining means usually secured to the back of the cover. l Difficulty has been experienced heretofore either in yinserting the leaves in the retainer and securing them in position or in holding them in position after they have been engaged by the retaining means, 'and at the same time providing for their ready removal either in regular order, as for filing, or singly as occasion may require.

It is the object of my invention to provide a simple device of this character in which the above, difficulties are met and overcome, and which may be manufactured at moderate cost.` y

With this object in view, my invention consists in the construction set forth in the followingclaims, and a preferred form of which is shown in the accompanying drawings and described in the specification. It will be understood, however, that the specic disclosure is for the purpose of illustration only, and the invention is not limited thereto, as many modifications will suggest themselves which come withinV the scope of the claims. Y

In the accompanying drawings illustrating the preferredform of embodiment,- Figure 1 is a perspective of a loose leaf binder with cover in open position; Fig. 2 is a fragmentary view in plan, one of the securing devices being shown partially in section; Fig. 3 is an enlarged section on the line 3-3 of Fig..2; Fig. t is an enlarged perspective of a detail; Fig. 5 is a central section of the retaining device; Figs. 6 and v7 are perspective fragmentary views illustrating a slight modification.

The cover or binder 6 may be of any usual or preferred form, and, as'shown, consistsk of a facing 7 and a stiifening member 8.

To the latter is secured a sheet metal strip 9 by means of a staple 10. Ateither end the sheet metal strip is bent up to' form a standard 11 of substantially circular form, which is perforated at 12 to receive the end of a shaft or lrod 13, the outer ends of which kmay be slightly upset to secure it against displacement. At one end the rod is provided with a small collar or annulus 14 rigidly secured thereto, and at the `other with a small finger wheel or disk 15, the edge of which is knurled to facilitate its rotation by the lingers. At suitable points along therod or shaft are arranged the retaining members proper, and in the present instance Iy have shown two such members 16, 16 consisting each ofa central disk or web 17, 17 surrounded by a ring or annulus 18, 18 which preferably extends equally upon opposite sides of the disk, though this is not essential. Each ring is split or open at one point in its periphery, as at 19, for the insertion of the loose leaves, and the web is slightly notched, at 20, in registry with the slit to facilitate this operation. The web forms a support for the flange, and, as shown, is imperforate, but obviously may be of skeleton or other suitable form. Opposite or in register with one of the retaining devices a ribl 21 is struck up from the support 9, and is adapted to enter the slit in the ring when the latter is `turned to Vbring thefslit and rib opposite each other.

The structure is suiiicient-ly resilient to per- Vmit the ring to be turned notwithstanding this engagement, when suflicient force is brought to bear by the fingers turning the disk L5. During this rotation the rib acts as a brake to hold the ring in any position to which-it may be adjusted.

The loose sheets are provided at suitable points along one edge with slits 22, 22 for receiving the flanges of the retaining devices yfrom the slits to the edge of the paper to accommodate the central disks or webs. It will be obvious that in order to insert the sheets in the binder, the openings lin the iianges, which, it should be stated, arein alinement with each other, are turned .away from the support which normally closes them, and the leaves inserted therein, a number of leaves being inserted at the same time, depending upon the widthof the slot or opening. When` a suiiicient pack of leaves has been engaged by the flanges, the retaining devices are turned until the rib upon the support engages the slot in the flange which is in register therewith. The retaining devices are thus secured with the openings closed by the support, and the binder is then ready for use. The leaves will be firmly held in position as long as required, yet they may be easily removed, either singly or in groups, by turning the retainers to open position. If it is desired to remove 'a single leaf located intermediate the top or bottom of the pack, it may be readily detached by a pull, the retaining ears of the sheet in engagement with the flanges yielding for this purpose.

In the modification shown in Figs. 6 and 7 the support 9, shaft 13, retaining member 16, and manipulating disk 15 are as described in connection with the form of device shown in,the remaining figures. I have added, however, a cover strip 24 which is superposed upon the strip 9, and the edges of which are turned down and under, as shown at 25 (Fig. 7) to embrace the lateral edges of the strip 9. The cover strip is cut out in the form of the letter H, as at 26 (see particularly Fig. 7 to receive the retaining members, the webs of which occupy the transverse slots 27, and the flanges the side slots 28, as will be readily understood from an inspection of Fig. 6. The package of leaves rests upon this cover plate when in use, and the tongues 29 of the latter eX- tend within the flanges and cover the slots therein when the latter are in the closed position.

What I claim is:

l. In a loose leaf binder, a support, a rotary shaft, a ring axially mounted thereon and having a slit for engaging loose leaves, and means engaging in the slit for locking the ring against rotation.

2. In a loose leaf binder, a support, a ring rotatively mounted in the support, and having a slit to receive loose leaves, and a web within the ring.

8. In a loose leaf binder, a support, a disk mounted thereon for rotation, an annular member surrounding the disk and having an opening for the insertion of loose leaves.

4. In a loose leaf binder, a sheet metal support, a disk rotatively mounted thereon and having a slotted flange, and a rib struck up from the support to engage the slot in the flange.

5. In a loose leaf binder, a sheet metal support adapted to be secured to the back thereof, end standards struck up from the support, a shaft journaled in the standards, disks mounted upon the shaft, annular flanges surrounding the disks and provided with openings for the insert-ion of loose leaves.

6. In a loose leaf binder, a sheet metal support, end standards struck up therefrom, a shaft journaled in the standards, a finger wheel for rotating the shaft, a plurality of disks rigidly secured to the shaft, annular flanges surrounding the disks and projecting on opposite sides thereof and having openings for the insertion of leaves.

7. In a loose leaf binder, a support, a disk revolubly mounted thereon, a flange on the disk having a transverse opening therein, a series of leaves each having a slot .and a notch receiving the flange and disk respectively.

8. In a loose leaf binder, a supporting strip 9 having standards at the ends thereof, a shaft journaled in the standards, disks upon the shaft having transversely slitted flanges, a cover plate secured to the strip 9 and projecting within the fianges on the disks to cover the slots therein when the retainers are in closed position.

9. In a loose leaf binder, a support, a shaft rotatively mounted thereon, a ring having an opening for the insertion of the leaves and rigidly mounted on the shaft in combination with leaves each having a slot and a notch from the slot to the margin of the leaf, the slots being positioned to engage the ring and the notches to receive the connection from the ring to the shaft whereby the ring may be completely rotated notwithstanding the presence of the leaves.

l0. In a loose leaf binder, a support, a lrotary shaft mounted thereon, split rings carried by the shaft, and means connected to the support and bearing upon one of the rings and adapted to secure the latter against accidental displacement.
