Application file d November 1,-1928.; Serial No. 316,471.

This invention relates to improvements in temporary binders, or loose leaf sheet holders.

The principal object of 1 this invention is to provide means for holding a single sheet of paper as well as an entire pack, ,or any intermediary quantity between a single sheet and an entire pack. Heretofore it, has been practically impossible to so adjust the holders that a single sheet of paper can be securely held, and under the same conditions, permit insertion of a largequantity of paper. In

my arrangement,fa single sheetof paper can throughout-the several views:

be just as securelyheld as an entirepack,

Another object is to provide an improved ratchet adjustinglmechanism for locking; the halves of the binder in-desired position. 7

Still another'object of theinvention is to provide an improved loose sheet holder-strucg ture.

Other objects will appear from the detailed V 1 I s j cured to the baseplate lof'cov'er 21s a broad description thereof.

The pair of covers 2 and 3 have, base plates 4:, u'sually'made of metal, bentin a longitudinally L-sh aped manner to 'form' the overlap ping ends and covered with material 5. Se-

fiatstrip of metal 6 withiits'ends 7 bent at right-angles and toothed at their side edges, 1 and secured to cover 3 is a similar member 8 havinghousings 9 at the ends to receive the I toothed ends 7;

The base portions of housings 9 are turned so as to form securing means 10 for the U shaped'wires 11, the' free ends of which oxtend upwardparallel tothe housings?) and are connected by toggles 12. The locking pins 13. of the toggles .12 slides in slots 14 in the outer face; of the housings 9] and project to the inner-faceof-walls of th-e'housings 9,

the ends of wires: 11 will be pulled into ratchet teeth 15 in the ratchet ends 7. Thumb portions 25hf the locking pins 13 of the toggle have their inner, flattened'heads 26 slldein the slots 14. WVhen the toggles are no 1 pushed upward so that the same locking pins are slightly above the ends ofthe toggles at the top of the" housing 9, the wires 11 will be pushed frointhe ratchet teeth 15 and the locking dii'ectly above the notches 16, whereupon the thumb portions 25 maybeturnedinto' locked position.

Secured to the u shape'd members Sand 87- r Wi g member 17 "J which are pivotaily pins '13 will-seatin notches 17 e5 connected to the members 6 and 8 by means of hinges 18. The Wing members 17 are L-shaped one edge forming the hinged portion and the other side adapted to back against the covers 2 and 3 when in inoperative position and forward against posts 22 when in, operative position} These hinges are formed of tongues of metal 19, which are taken from the respective members 6 and 8, passed through openings 20, in the .wing

members 17 and bent around to form a hinge. Posts 22 are supported by the U- shaped members 6 and 8 and have shoulders 23 formed thereon by flatteningthe outer portions of the. posts so that the wing members 17 which have corresponding'ciut out portions 27, maybe supported by, said shoulders, when the wings 17 are in use.

lVhen not in use, the wings will be folded back out of the way and held in such position by the placing of paper on the posts. The two members 6' and Ssupport posts 22 in staggered relation, when'the covers are brought together, as well as the wing members 17 'Oppo'site the posts 22 are openings in the respective members 6 and 8 to receive the respective posts. Rivets 24L pass through the cover 2 and 3 to secure the U-shaped members'to thebaseplates I I Figure 13 shows a modified torm' wherein isused instead of thetoggle jas shown. in the gures, astraight bar 28 secured at one end to one of theU-shaped wires 11, the

other end having a shoulder 29 which bears against the othe'r'leg of the U-shaped wires to force the same out of engagement with, the ratchet teeth when the bar is horizontal and permits the wire to spring into engagem'ent whenjthe bar is lowered. I f i Asactually used, the paper is placed upon a quarter turn and theloching pins raised to the upper notch, the thumb portionturned to lock the same against accidental displacement, and the upperhalf of. the cover lifted from the lower half which permits therenoval of the paper or any proportion. there'- of. If it is desired to secure a single sheet of vpew a l m te ame nt of pera'f the binder, the wings 5'17 f, ;are fo1d d over.

against the posts in" each 'co'vr',"so that the Wings come to rest on the shoulders on the posts. The paper is then placed in the cover 'containingthe housing, and the same operation disclosed aboveis repeated. Thetwo planes of the wings in the respective covers will be placed as closely adjacent each other as possible, regulated by the adjustable ratchet and toggle mechanism, only thethickness of the varying quantities of paper separating thetw o. Thispermits of a single piece of paper being held just as securely as a:larger amount. When a large pack of paper of an inch or more thickness is de sired'to be placed in the binder, the wings may be folded back parallelto the back of the halves v as shown jin Figure 9 and the full quantity iplaced onthe posts], ithoutjthe use of'fthe wings," it isfim'possible t h d a i gl h et of pape .i eh v n place or an amount oif' pape'rofjle'ss thickness than the depth, of onev of the covers, whiclfr causes the paper thus held tollbeeomc dislodged and torn'ffrom the posts which is a very undesirable condition.
