Description

Oct. 31, 1939, E. G. DoRTcH LOOSE-LEAF BINDER Filed Dec. 27, 1938 INVENTOR ATTORNEYS Patented Oct. 31, 1939 "UNITED stares PATENT OFFICE 2 Claims.

This invention relates to loose-leaf binders and has for an object to provide a loose-leaf binder which will be devoid of posts.

A further object is to provide a loose-leaf binder having a pair of lever operated hooks mounted on the back of the binder and adapted to hook into recesses in the edges of the leaves to detachably secure the leaves in the binder.

A further object is to provide a device of this character which will be formed of a few strong simple and durable parts, which will be inexpensive to manufacture, and which will not easily get o-ut of order.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modiiications may be resorted to Within the scope of the appended claims without departing from the spirit vor sacrificing any of the advantages of the invention.

In the accompanying drawing forming part of this specification,-

Figure 1 is a rear elevation of a loose-leaf binder with a portion of the back broken away to expose the lever operated leaf engaging hooks.

Figure 2 is a fragmentary side elevation of the binder shown in Figure 1 with portions broken away.

l Figure 3 is a detail perspective View of one of the lever operated hooks.

Figure 4 is a fragmentary perspective view of the binder leaves showing the notches therein for receiving the hooks.

Figure 5 is a fragmentary cross sectional view taken on the line 5 5 of Figure 2 showing the channel member for receiving the rear edges of the leaves.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, the loose-leaf binder comprises a flat sheet metal back I having the edges rolled back to form hinge eyes I I to receive hinge ointles I2 which are passed through hinge eyes I3 carried by the stiff side covers I4 of the book, .here being slots I in the hinge eyes of the back, ts shown in Figure 2, to receive the hinge eyes if the side covers.

A channel member I6 is riveted or otherwise :ecured to the sheet metal back I0 to receive' he rear edges I'I of the loose leaves I8. The :hannel member holds the leaves accurately tacked to locate transverse grooves I9 of the eaves, shown in Figure 4, in position to receive he locking hooks later described. A removably (Cl. 12B-18) mounted back member 20, of concave contour, is provided with a plurality of cross members 2| which terminate in resilient hooks 22 that embrace the hinge eyes I3 of the side walls I4, as shown in Figure 5, to detachably mount the mem- 5 ber in place. This back member forms a housing for the locking hooks about to be described.

`There are two locking hooks 23, preferably formed of sheet metal, one of which is shown in Figure 3. The flat Shanks of these hooks extend oppositely to each other along the sheet metal back I0 and the free hooked ends 24 are adapted to be received in the grooves I9 of the leaves I8 to hold the leaves clamped in the channel member at the upper and lower edges of the leaves. The opposed ends of the locking hooks are connected to respective ends of a short lever 25 which is pivot-ed intermediate its ends as shown at 26 in Figure 1 upon the metal backl 0 at about the center thereof. One of the hooks is equipped with a handle 2l which is secured at one end as sho-wn at 28 to the hook and at the free end is bent laterally to provide a grip 29 through the medium of which the handle may be pulled outwardly or shoved inwardly to correspondingly move the hooked ends 24 of the locking hooks out of or into engagement with the grooves I 9 of the leaves I 8.

In operation when the hooked ends 24 of the locking hooks are engaged in the grooves I9 in 30 the ends of the leaves I8, the leaves are held securely in the channel member I 6. When the grip 2S of the handle 2l is pulled outwardly the respective locking hook 23 is moved outwardly and rocks the lever 25 on its pivot to simultane- 35 ously move outwardly the companion locking lever 23 and disengage the hooked ends of both locking hooks from the grooves in the leaves.

From the above description it is thought that the construction and operation of the invention will be fully understood without further explanation.

What is claimed is:

l. A loose-leaf binder comprising a back, covers hinged to the back, a channel member extending longitudinally of the back, leaves confined at the rear portions thereof in the channel member and having a line of transverse grooves in the top and bottom edges, hook members slidably mounted on the back and projecting from respective opposite ends of the back, a lever pivoted intermediate its ends on the back and pivotally connected to opposed ends of the hook members, and means on one of the hook members for movne Q back element in place, a channel member secured to said back plate, leaves having the rear portions removably tted in said channel member and having transversely aligned grooves on the `top and on the bottom edges, and hook members slidably mounted on the back and housed by said removable back member, said hook members being adapted to be engaged in and disengaged from said grooves.
