Inthe invention I have illustrated a bar 9.Wh'ich is provided with openings 10 through Whichfastening meansmay be projected for securing: the bar 91o a cover or other suitable support.v A plate 11, preferably. formed fromzsheet metal, is provided with the doubled over end 12, a notch 13 being cut out of the plate 11 and the doubled over portion 12fati the juncture of these tvvo parts. At the opposite end of the plate 11 tongues 141 are bent out. At the forward .end of the plate .50' 11. thereisprovided an upwardly offset or 1928. Serial No. 284,951.

raised portion 15 in which is formed an opening 16, the rear side of this opening being straight as appears in Fig. 4. Punched from the plate 11 and extended downwardly are tongues 17 behind which and against. which is adapted to engage the end 18 lof a. Zishaped sln'ing.y the opposite end 19 bein positioned in a slot 20 formedin the end o the binder hook 21. After engagement of the endA 19 in this slot the prongs atopposite sidscf the slot are clinched so that. the member 19 is securely fastened in the slot 20, While at the same time, the hook 21 is free for pivotal movement, on the member 19 as an axis. Formed in the inner side of the forwarder tree end of the hook 21 is a notch 22 adapted, when the hook is movedto closed position, for receiving the straight edge of t eupset portion 15. When mounted on the bar 9`tlie portion 12 is doubled over so as to clamp the har 9 against the plate 11 andV the tongues 14 are angularly turned ,for serving the same purpose as appears in Fig. 2. If desired, these parts 12 and 14 may be so pressed against the bar 9 as to secure the hook in fined relatin on the bar 9 or they may be loosely bent to permitslidablemovement so that the location of the hooks on the bar 9 mayY be varied.

In use, when it is desired to place. leaves in the binder the hook may be moved to the dotted closed position shown in Fig. 2,.this forward movement of the hook bodily bein permitted by the size of the opening 16 and the size of the notch 19 and the resiliency of the Z-shaped spring, the portion 19 being moved bodilT to. approach the portion 18. Then moved to this position the hook .may be sii/ung upwardly and rearwardly on the portion 19 a pivot into the open vposition shown in dotted lines in Fig. 2. When moving the device to closed position a pressing dmvnwardljT will eii'ect a forward movement of the part 19 sufficiently to permit the end of the hook 21 to enter the upset portion 15, the resiliency of the Zeshaped spring bein suticient to move the freeend of this hoo riruardlyso as to permit the rearor straight edge of the upset portion 15 to engage in the notch 22. This spring is sufficiently strong to normally retain these parts in locked relation so that undue displacement of the leaves from the binder resulting from disengagement of tbe hook from its locked position is reduced to al minimum.

In the form shown in Fig. 5 I have indicated the bar 9 which is equivalent to the bar 9, as formed integral with the plate 11 which is the equivalent of the plate 11. This plate 11 is provided with the tongues 17 corresponding to the tongues 17 and With the notch or slot 18 corresponding to the notch or slot 13. The portion of the plate 12 extending outwardly from the dotted line of bend indicated by the numeral 27 corresponds to the portion 1Q. so that when these parts are folded over into the relation shown in Fig. 6, the same operation and functioning of the device is provided as explained for the preferred form. the hook 21 being opeated upon by the Z-sliaped spring having the parts 18 and 19.
