A'key 9 of the sections 7. Leaf or sheet receivingposts snap 38 in the form of a forked lever is provided 10 normally extend inwardly in opposite direcwith a pair of opposedlegs 39 straddling the head tions from removable strips 11 to which they are and having trunnions 40 thereon each of which rigidly secured. Suitable lugs 12, provided on is disposed in arecess 41,extendingradially in 55 gage the outer surface of the pin 24 and the innei i 30 the head 37. It will be observed that the trunnions 40 are spaced from the ends of the forked portion of the key snap which rest upon or adjacent the washer 25.

In the position of the parts as illustrated by .Fig. 2, the key snap 38 is lying flatly upon the surface of the flange 9 and the balls 32 are pressed by the energy of the spring 33 against the surfaces of the'conical portion 26 and against the shank of. the pin .24. Thus the cover sections are held in proper binding relation. However, by

manually lifting the outer end of the key snap 38 until it is in the position shown by Fig.3, the

forked ends 39 engage the washer 25, theyjslide thereon, and the. stud 36 is drawn outwardly against the force exerted by the compression spring 33. Then the pin 24 is released andcan 'be withdrawn from the core 27; If desirable the stud 36 can be unscrewed from the stem 34 and the key 35 removed entirely, thus permitting the ,locking device to "remain-locked to the pin 24,

The binder canthen be tightened by pressing thefianges 9 toward each other, but cannot be unbound until the key is applied and manipulated in the manner described. It will be notedthat thekey snapin itsextreme operative position-as shown'by Fig. 3, extends in a direction axially of the cylinder 22 orat right-angles te -the. bar 8. In this 'position -the key snap is in its dead-center position with respect to the spring3 3 and it then canbe made to snap automatically in either -di-* rection until it lies substantially flush-with--thesurface of the flange 9. In'manipulating'the'key snap- 38=the forked ends 39 thereof perform a cam-like action'upon the washer 25 and extend through the openings 42 of the flange 9 which register withthe washer. Suitable n'otches 43 in the strips 11 receive the casing 22 and-pin 24 when the parts of the device are in assembled relation. ,--From the foregoing description it will be apparent that the construction embodying themvention provides for'the proper securing together key.

"Although only one form ef the invention has been shown and described in:' detail it will be apparent to those skilled in theart'that the invention is not so limited'but that various changes may be made therein without departing from the spirit of the invention or from the scope of the appended claims. v 1 -i What is claimed is:-

, 1'. In a loose leaf binder, a pair-of binder sections movable toward and away from each other;

leaf-receiving posts projecting inwardly in or:- posite directions from the sections, telescoping clutching members secured to the sections for releasably securing the sections in binding relation, one of the clutching members having a spring normally maintaining said members in clutching relation to permit movement of the sections toward each other but positively opposing separation thereof, a keyremovably secured to one .of-the clutching members, said key including a member having camming action upon one of the sections to force said one of the clutching members into inactive relation against the action'of the spring, said member adapted when partially returned'to automatically snap back into inoperative position, whereby the clutching members are again active in preventing separation'of the sections.

2. Ina loose leaf binder, a pair of binder sections movable toward and away from each other, leaf-receiving posts projecting inwardly in opposite directions from the sections, means for re:

movably mounting the posts in the binder, a one-way clutching mechanism securingthe sections together,'-a key removably connected to one portion of the clutching mechanism for controlling the clutching mechanism, said key in-'" 3. 'A manipulating device for loose leaf binder fasteners comprising a body portion having fastening means thereon, and a member having a pivotal connection on the body portion, said member having a manually operable extension on one side of-the pivotal connection and a binder-engaging extension on another side of the pivotal connection. 4. In a loose leaf-binder, a pair of separable binder sections,f-posts mounted upon the binder sections, interfitting clutching members on the sections having cooperating parts operable to provideclutching-engagement between said mem bers in anyinterfitting position for maintaining them in book-like form,-a key for operating said members'to disengage said cooperating parts of the clutching members, and resilient means for normally actuating said clutching members into clutchin g'relation, said key having coacting. connection wi'th one of the clutching members and means cooperating with one of said binder sections movable to produce a snap action of said key into a position to insure automatic locking of the clutching members.
