LOOSE-LEAF BINDER.

Application filed May 18, 1925.

This invention relates to loose-leaf binders, and particularly to a binder intended and adapted to hold checks, printed matter, sample materials in sheet form, or other leaves which will be considerably thumbed in use, and which must lie comparatively fiat when the book containing the same is opened.

An object of my invention is to provide a binder which will take a quantity of leaves or sheets and will hold the same conveniently and compactly in place, the binder being of such construction that one or several leaves can be thrown over or turned back to give complete access to any particular sheet or leaf.

A further object resides in so constructing and mounting the parts that no obstruction is placed upon the binder rings or posts to tear the leaves, and that the leaves will be protected and supported when the binder is being opened. I I

Yet another object is to provide a binder of the ring type in which the leaf or sheet opened position. I i

Fig. 3 is a top plan view of the disclosure receiving portions of the rings are continuous, and in so mounting the rings or posts that they are movable to permit one or several leaves or sheets to be turned back to lie perfectly flat thus giving complete access to any matter upon the leaves or sheets and presenting the leaves in the best position for writing or working upon the same.

\Vith the above and other objects in view, which will be apparent to those skilled in the art, my invention includes certain novel features of construction and combinations of parts which will be set forth in. connection with the drawings.

In the drawings:

Figure 1 is a view in perspective of a binder constructed in accordance with my invention, showing the top cover opened out.

body of leaves about to be thrown over to the open position.

i Fig. 7 is a similar sectional View with a portion of the leaves opened as shown. in Fig. 2.

Fig. 8 is a perspective view to better show the binder bar and rings;

Fig. 9 is a fragmentary perspective view of one end of the throw-over board.

Fig. 10 is a detail perspectiveview of a modified form of leaf retaining clip.

The binder cover consists of the two

side members

1 and 2 connected together and spaced by a back hinge strip 3, and it will be appreciated that these covers can be made of any suitable material and can be bound to meet the particular requirements of use. It is perhaps preferable that the cover memher 1 be relatively stiff as the binder structure is supported and carried thereby,but this member 1 and the remaining portions of the cover might be a flexible material where the conditions of use require.

A binder bar 1-, preferably of cylindrical metal, has its ends bent and formed to provide open rings 5 and 6', said open rings lying in parallel planes at right angles to the axis of the body portion 7 of bar 1 and being so formed that the rings are disposed sub stantially concentrically around the body portion 7 as a center. The free ends of the rings are notched or grooved at 8 and 9, and it may be found advantageous to shape these ends to be of substantially ball form beyond the

notches

8 and 9. Bearing members 10 and 11 are riveted or secured in any other suitable manner upon the inner side of cover member 1 adjacent and spaced from the back portion 3, and these bearing members are provided 'with upstanding aligned

hinge bearing portions

12 and 13. The bearing

portions

12 and 13 are adapted to revolubly mount the bar 4 and are spaced apart to embrace the body 7 thereof adjacent the

rings

5 and 6. The hinge bearings are elevated sufficiently that the rings will nearly clear the cover member 1.

As it is desirable that the turning center of the

rings

5 and 6 be; kept as close to cover member 1 as possible, I have found it advantageous to notch the inner face of the cover as indicated at 1 1, to provide clearance for the

rings

5 and 6, and a more compact cover is secured by providing similar notches or recesses in the inner face or cover member 2 to receive the upper sides of the

binder rings

5 and 6 when the cover is closed.

It is desirable that a throwover board 16 be provided to be fitted on top of the body of leaves or sheets held by the

rings

5 and 6, and I have provided a spring clip 17 secured in conjunction with the throw-over board to engage with the notched ends of the rings and retain the throw-over board in place, consequently insuring that leaves or sheets will be retained upon the binder rings. This spring clip 17 has keyhole shaped

openings

18 and 19 formed near the ends thereof and so spaced that when the body or the clip shown in Figs. 2 and 7.

is flexed the ends of the

binder rings

5 and 6 can pass through the enlargements or these

openings

18 and 19 and when the clip springs back the reduced ends of the keyhole openings will catch within the notches or

grooves

8 and 9 of the rings to retain the clip in place.

I have shown the sheets 20 as leaves or a checkbook perforated at 21 to be torn off to leave stubs 22 upon the

binder rings

5 and 6, and in this adaptation the throwover board 16 will be made of a length to accommodate the length of the stubs 22. Tins throw-board covers the stubs to protect the same from wear and from the sight of unauthorized persons when the book is opened to give access to the body of the leaves which constitute the checks, and when the user desires to make entries upon the stubs or wishes to read or thumb over any of the stubs, these can be readily lifted with the throw-board and can be turned back to lie flat upon the cover portion 2, as particularly In throwing back the board 16 and any leaves, the bar 1 is revolved within its mounting in the

hinge bearings

12 and 13, and the binder rings turn therewith With a wheel-like motion.

In Fig. 10 I have illustrated a modified form or clip 23 adapted to be fitted upon the notched ends of the

binder rings

5 and 6 to retain leaves thereon, and in this construction a substantially U-shaped bar is made of sufiicient length to extend across from the end of the rings 5 to embrace the end of ring 6, this U-shaped bar being preferably closed at its end as at 24 to hold against endwise withdrawal from the notched ends of the rings and being slightly contracted at 25 at its edges adjacent the ends so that it will spring or snap over the ball ends of the rings to engage within the'notches 8 and 9.

While I have herein shown and described only certainiparticular and specific embodiments and uses of my invention, it will be appreciated that changes and variations can be made in the form, construction and arrangement ot the parts to suit different conditions of use, without departing from the spirit and scope of my invention.

I claim:
