LOOSE-LEAF BINDER.

Specification of Letters Patent.

Patented March 17, 1908.

Application filed June 13, 1907. Serial No. 378,730.

T 0 all whom it may concern:

Be it known that I, HERMAN M. ADLER, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in LooseLeaf Binders, of which the following is a specification.

The present invention relates to binders or covers for loose sheets of paper, in which the sheets may be securely held against possibility of accidental removal, and may be turned as the leaves of a book.

The particular object of the invention is to enable the same devices which retain the leaves in the binder to be employed as guides along which the leaves may be slid when being turned, and also as clamps to press the sheets and covers closely together when the binder is closed.

Accordingly the invention consists of the clamp or lamps illustrated in the accompanying drawings, in combination with the cover and leaves of a loose-leaf binder.

Of the drawings,Figure 1 represents a sectional view of a binder embodying my invention, in open position. Fig. 2 represents a perspective view of the same binder closed, with the leaf guides operative as clamps. Fig. 3 represents a fragmentary sectional plan view.

The same reference characters indicate the same parts in both figures.

In the drawings, 1 and 2 represent the stiff boards or leaves forming the covers of the loose-leaf binders, and 3 represent the loose sheets of paper or leaves which can be readily inserted and removed from between the covers. The cover leaves have eyes 4 and 5, and the loose leaves have alining perforations to receive the binding and guiding rods or bars 6. These rods are inserted through the eyes and perforations which are in alinement, and when in place, serve to prevent the loose leaves being removed.

Each of the guiding and binding rods is formed with an offset or coiled portion 7 at one end, which forms a head, to prevent that end of the guide being drawn through the eye and the cover separating from the other parts of the binder. hen the binding rod is passed through the cover 1, it is turned in the same manner as a screw, so that one of the convolutions of the coil will bear against the inner surface, while the next adjacent l convolution bears against the outer surface of the cover, the inclined connecting element of the convolutions then passing through the eye. Thus the cover is gripped by the coils of the head and the binding rod is retained frictionally in any position which it may 00- cupy, while it is iirmly held so that its shank extends upright from the cover. Between its ends, at the point 8, the rod is sharply bent through more than a quarter turn so as to provide an arm 9, making an acute angle with the shank of the rod which passes through the perforations and eyes. The other end of the rod is somewhat oll'set so as to prevent accidental removal of the second cover 2, while permitting the withdrawal of the fastening rods without dilliculty, when such withdrawal is necessary. The offset at this end also forms a smooth surface when the holder is used as a clamp, and thus prevents scratching of the cover.

Figs. 1 and 2 represent respectively the two functions which the holders 6 perform, in addition to that of preventing dislodgment of the loose sheets. It will be seen in Fig. 1, that the'binding rod is turned or swung about its shank portion so that its arm 9 extends substantially perpendicularly to the rear edge of the binder. This allows the upper cover and the loose sheets to be turned over and laid with the inner side up, the binding rods then serving as guides along which the cover and leaves are slipped until they arrive at an inverted position. In Fig. 2 the binder is shown closed and the arms 9 are swung inward so as to lie approximately parallel with the rear edge of the leaves. As the binding rods are made somewhat resilient and bent at less than a right angle, the ends of the arms 9 are caused to bear with some force against the upper cover 2, while the coiled heads 7 grip the cover 1 between their convolutions and thereby provide a firm support for the lateral arms 9 to take the reaction of their pressure on the cover 2, so that the leaves are pressed tightly together and the binder is held firmly closed.

The binding or holding rods are made of a material which is sulliciently ductile to be bent into the shapes illustrated, and is capable of being tempered so as to retain these shapes and to be resilient. The preferred material for this use is steel wire, though other substances and other forms than that of wire may be employed. If desired, also,

the head 7 may be formed as a spring so as to bear yieldingly on the cover to which it is ad jacent.

I claim 1. A loose-leaf binder comprising cover leaves having eyes, and bent resilient bars passing through said eyes, adapted to have the loose .leaves threaded over them, and to serve as yielding clamps to press the leaves together.

2. A loose-leaf binder comprising cover leaves having eyes, and bent resilient bars passing through said eyes, adapted to be placed in different positions, serving as guides for the leaves when in one position, whereby the covers and leaves may be opened in the manner of a book, and as clamps when in another position to hold the binder closed.

3. A loose-leaf binder comprising the leaves or boards forming the cover and having eyes, and a resilient rod passing through adjacent eyes, having a head at one end and bent between its ends so as to serve when in different positions respectively as a clamp and as a guide about which the leaves may be turned.

4:. The combination in a loose-leaf binder of leaves or boards forming a cover and having eyes, perforated loose sheets, and spring rods passing through the eyes and perforations, each rod being bent to provide an arm adapted to lie against one of the cover leaves for clamping the leaves together, and to be swung outward from the adjacent edges of the cover leaves and sheets so that the covers may be opened and the loose sheets turlned while remaining in contact with the rec s.

5. The combination in a loose-leaf binder of leaves or boards forming a cover and having eyes, perforated loose sheets, and spring rods passing through the eyes and perforations, each rod being coiled at one of its ends to form a head lying against one of the cover leaves, and being sharply bent between its ends to form an arm adapted to bear yield ingly upon one of the cover leaves and 'to be swung outward perpendicularly to the adj acent edges of the leaves and sheets, so as to permit the covers to be opened and the sheets turned and slipped along the rods while remaining continuously in engagement therewith.

6. A loose-leaf binder consisting of covers, and holding rods or bars passing through eyes in the covers and bent over on the outer side of one of them, said rods or bars being formed than the distance from the eyes to the nearest edge of the binder, whereby the adjacent cover and loose sheets may be opened and turned as the leaves of a book while'remaining in engagement with the arms.

7. A loose-leaf binder consisting of covers, and holding rods or bars passing through eyes in the covers and bent over on the outer side of one of them, said rods or bars being formed with arms of greater length than the distance from the eyes to the nearest edge of the binder, whereby the adjacent cover and loose sheets may be opened and turned as the leaves'of a book while remaining in engagement with the arms, and the arms having provisions at their ends to prevent disengagement of the cover.

8. A binding rod for a loose-leaf binder formed from a resilient rod or wire, having its ends offset to provide retainers, and being intermediately bent to form a part adapted to pass through the eyes of a binder and an arm extending at an acute angle therewith, to guide the leaves when the binder is open and clamp them yieldingly together when closed.

9. In combination with the cover leaves or boards and loose sheets of a loose-leaf binder, the leaf guides passing through perforations in the leaves and sheets for holding the sheets in place and guiding them when turned open in the manner of the leaves of a book, and adapted to serve as clamps to retain the parts of the binder in closed position.

10. A holding or binding member for loose-leaf binders arranged to serve as a retainer for loose sheets and provided with a laterally extending arm forming a guide for the sheets when being turned and a clamp to hold the binder closed.

11. A holding or binding member for loose-leaf binders having a coiled head at one end to grip between its convolutions one of the covers of the binder, and having a resilient lateral arm to press against the other cover and hold the parts of the binder together.

In testimony whereof I have afliXed my signature, in presence of two witnesses.
