LOOSE LEAF BINDER Filed May l5, 1950 Patented Dec. 15, v1931 limi lssazao l STEEN, GF CHGAGO, LLl'IS, ASSIGNOR {[OV Il. M'. STEIN COMPANY,`OF CHICAGO, ILLN 01S, .A'CORPORATION OE ILLINOIS LOOSE LEAE BXNDER Application mea May 15, i930. semi No. 452,553.

rl`he invention relates 'generally to loose leaf binders of the type in which the leaves or sheets are secured by a plurality oflspaced parallel posts between two pivoted wings on the covers of the bindenthe posts being fixed on onewing and detachably secured to the' other.

rlhe wings of the binder are usually formed from metallic bars pivotally secured to cloth- Y binder, and have interfered with the operation of applying the fabric covering.

An important object of the present invention is to provide a loose leaf binder construction in which the posts may be attached to one ofthe .ving bars after the fabric has been applied, whereby to facilitate the manufacture of the binder. Y

Another object of the invention is to provide in a loose leaf binder.having a post adjacent to the top andvbottomedges'of the iinder, individually operable locking devices whereby the free ends of the two posts may be detachably secured to one of the wings one at a time.

another object of the present invention isV to provide a binder of this character having' a' wing constructionembodying means for securing the post to the wings and arranged to provide smooth outer surfaces on the Wings so as to avoid any irregularity in the outer surface of the wings tending to cause wear on the covers. 7

Another object of the present invention is to provide a locking slide having new and improved gripping means for manually mov ing the shde7 the gripping means having an operative position wherein it may be firmly sped bv an operator and-being movable ively tothe slide to anv out-of-the-way position in the space between the end edges of the leaves and the end edges of the covers wherebyto permit the binder to be stood on edge. i y Y Y ther objects and advantages will become apparent from the following description taken in connection with the accompanying drawings, in which:

lWhile the invention issusceptible of various modifications and alternative constructions, I have shown in the drawings and will herein describein detail'the preferred embodiment, but it is to be understood that I do not thereby intend to limit the invention to tbespecilic form disclosed, but Vintend to cover all modifications andalternative constructions falling within the spirit and scope of the invention as expressed in the appended claims.V

In the preferred form illustrated, theinvention is embodied in Va binder having a pair of similar fabriobound covers l0 flexibly connected together Corresponding edges by a flexible back il; For the purpose of detachably securing suitablypunched sheets of paper or thelike in the binder, a pair of wings l2 and 13 are pivot-ed, one to 'each of the covers l0 for swinging movement relatively to the covers, and a plurality of posts lllfetend between the two wings, each post having one end fiXedlymount-edrin the wing l2 and -detachablyseoured at its other end to the other wing,` 13. lVith such a construction, the wing' 13 may be detached and moved away from the ends of the posts 14 and suitl purche-:l sheets et pap-er slipped over the projecting 'tgee eids the posts, after nunc-h the paper may be held n1 place ni securing wing 13 to the.

It also facilitates the ixing of the lookin@l slide in the member 15 since the plate 'lZ' may be struck downwardly after he parts have been embled to forni a boss 127 which interloeks with the slide (F l In the performance et such a lixinzg;` operation the plate 18 is not ...orteil and. thus its .smooth outer surface is retained and uneven wear ot the Cover 10 prevented.

To receive the headed ends 40 of the posts, the plate 3G of the member 35 has a pair of transversely extending slots or openings 4l. which in the present ease extend to a point near the edge ot the plate 3G which is fixed to the Connecting portion 38. Vhen the heads fl() o the posts have been moved through the slots 1-1 and into the spa-ee between the two plates 3G and 3? they may be detaehably secured in this relation to the plates by looking means which is n'iovabie lon. tndinally in the space or passage be- Uveen the two plates.
