Patented June 7, 1938 2,120,086 UNITED STATES PATENT OFFICE ‘2,120,086 LOOSELEAF BINDER Raymond S. Brown, Columbus, Ind. Application -March 13, 1936, Serial No. 68,704 '13 Claims. The present application relates to a loose leaf binder, and more particularly to a binder :or holder for a sheaf of loose vpapers, primarily in tended -to;be used as a scratch pad. A primary ‘objectof the invention?s to :provide a~device of ‘the type indicated ‘which can be used to bind unperforated sheets of standard size; so that its use will not ‘only be Bless expensive than 5 the use of ‘holders of the type ‘which require 10 perforated paper, but will also be less trouble some; in that the paper 'may 'merely be slipped into place in the holder, and then ‘clamped in position. the description proceeds. ‘ commercially, toengrave, emboss, or otherwise >2 apply such advertising legend to the separate plate than to cross bar 16. The bar 16 is provided, at its edge adjacent to V the pivot axis I3, with a down turned lip I845 which is adapted to be pressed in clampinglen gagement with the sheaf H of paper. The .pro vision of the lip I8, not only makes for more satisfactory gripping of the paper, but improves the capaoity'of the clamping means for provid- ‘11.0 ing for smooth tearing of the sheets along the line of engagement of the lip I78. 7 Immediately adjacent the end of the base I0 Further objects of the invention will ‘appear'as 15 (Cl. 129—35) nearest the cross bar I6, there is mounted an ‘To the accomplishment of ‘the above and ‘re lated objects, my invention maybe embodied in upstanding screw I9 which is suitably secured..15 to the base and is held against any movement with respect thereto. A nut .20 is vthreadedly the forms illustrated inthe accompanyingdraw mounted onsaid screw I9,-and-is adapted'to be ing, attention being called to ‘the fact, however, that "the drawing is illustrative ‘only, and ‘that change may be 'made in the speci?c construc engaged in a notch 2| formed in the adjacent edge of the cross bar l6. As is clearly illustrated .20 in Fig. 2, the lips 22 and .23 of said notch 2| ' tions illustrated and described, vso ‘long "as the scope "of vthe appended ‘claims vis ~not violated. Fig.' 1"is a'perspective View of ‘a binder con are bent ‘downwardly at approximately the axes or points 24, 24; and, as is indicated in Fig.4, said lips are .further bent-downwardly about -an structed :in accordance with "the present inven tion, with which is associated a sheaf of papers; vaxis substantially perpendicular to‘the axes-'24, 24, :25 Fig. '2 is an enlarged fragmentary "end eleva tion thereof; ‘Fig. 3 'is a plan view thereof ‘with the 'papers removed; ‘ ‘Fig. '4 'is a fragmentary longitudinal section ftaken‘substantially'upon line 4—-4 of Fig. 3 and looking in the direction of the arrows; .and Fig. 5 is 'a fragmentary "end ‘elevation similar to Fig. 2 "but illustrating‘a ‘modi?ed ‘form 'of‘the invention. Referring more particularly'to the drawing,‘it will be seen that I have illustrated a'base I I] of suitable dimensions ‘for supporting ‘a sheaf ‘of 4.0 loose papers ‘I I. Upwardly projecting from ‘its opposite edges are ears or ?anges I2‘which serve as guides ‘in inserting a sheaf of papers, and which further provide supports‘to‘which levers I4 and "I5 maybe pivotally secured'by means of hollow rivets I3, or the like. The ‘free ends of the levers “and ‘I5 areconnected by a crossbar ‘I6 which, in the illustratedembodiment of the invention, is integral with said levers. Preferably, ‘the ‘bar 46 -is of su?‘icient size, "in U1) the direction of ‘the length of the base I0, to hear an ‘advertising legend; and, in the illus trated embodiment of the invention, I have pro vided'a separate plate I‘! secured to the upper surface of the cross bar IS in any suitable man ‘ her, with the idea that it-will beless expensive, as at 25. ' Adjacentits bottom end, the nut 20 is formed with'a circumferential groove 26 bounded at its upper edge by a substantially ?atsurface'or wall 21, and at its lower edge by a chamfered wall or 30 ?ange 28. The ‘lips 22 and 23 are engaged in said groove \26; ‘and it will be seen, therefore, that ‘rotation of the nut in one direction will ‘positively move the bar l6 toward the base ‘Ill, while rotation of the nut in the opposite direction;.35 ' will positively move saidrbaraway from said base. The manner in which the lips Hand 23 are bent downwardly about the axes 24 and .25 is such that, as the bar 16 moves about its pivotal axis I3, in a counter-clockwisedirection as viewedAO in Fig. 4, thus being drawn toward the left 'as viewedgin Fig. 4, the portions of the ‘lips which engage with the walls of the groove 26 remain substantially perpendicular ‘to vthe axis vof ‘the screw I9. ' That surface of the screw ’ I9 which faces away from the adjacent end of the'base IO‘is ?attened, as at 29. Thus the screw may be used as an abut ment for determining the degree of =insertion'of _ the paper into the holder, and yet the individual sheets do not tend to 'hang'up on the threads of the screw, since the ‘threads are eliminated onithat‘portion of the screw which is engaged " by the paper. .

A loose-leaf binder comprising a base hav ing a ?at portion for supporting a sheaf of pa-. pers, a pair of leverslpivotally mounted upon aligned axes'on opposite sides, of ‘the ?at por tion of said base and intermediate the ends there Preferably that end of the base remote "from the screw I9 is formed with a thumb notch 30. It will be seen that I have provided a holder ' comprising a base, a bar adapted to cooperate .with said base to clamp a sheaf of paper on said base, said bar'being mounted upon a .pair ' of to lie beyond the edges of said papers, at barv joiningrthe free ends of said levers, and means of levers'of the'second class, the load being the sheaf of leaves 'to be compressed, the fulcrums for said levers lying in, or adjacent to, the pro 10 jected side area of the pad. The levers lie‘close providing a connection between’said bar and said‘ base for causing said bar to exert a'retain 10 ingpressure upon said papers. 4.' A loose-leaf binder comprising a base, a‘pair' 1 alongside the padof ‘paper, thereby aiding in aligning the individual leaves of the sheaf; and, the 'fulcrums being positioned as they are, the whole unit is quite compact. The means for 15 forcing the cross bar into clamping relation with the sheaf of; paper is positioned :outside the '7 boundaries of the sheaf, which makes it unneces _ sary to use holes or notches in the leaves, so that re?lling of the pad is very inexpensive. . 20 _ vWhile the above described organization is use ’ful primarily as amemorandum pad, it could be " used in: an enlarged form for l?lingrcorrespond ence and other papers. ‘Preferably, however, a different form of holding means for the cross bar would be usedain, 7'such1a‘ho1der. In Fig. ,5, I have illustrated a base 3!, adapted to supporta sheaf .25 32 of letters, or the like, there being provided a ‘\cross'bar'33 similarin substantially all respects , to" the ‘cross bar‘ IEQ and pivotallysupported on 30 levers similar to the'levers I4 and I5.
