Description
J. DAWSON LOOSE LEAF BINDER Filed June 27, 1930 Patented Aug. 30, 1932` Reves', Mrss'o'nir; AssIev'oR- 'ro num N j DAwsonf A PATENT OFFICE or wBs'iER enovns, MISSOURI scese-LEAF minimi Application inea fune av, leso." seriai No. 464,23r.
This invention relates to looseleaf binders and particularly to theconstruction of angle bacia binders, Previously when cloth or thin leather has been used as the covering material forthe book, it has been necessary 'to cut the margin tov allow the n iaterial' tobe'folded4 over th'erangle back. When fabric covering material-isused,th:is is extremely undesirable since thesel'vage of the materifalmust be cut.-
Heretokfore, when nopaper was in the binder,-consi'd'erable looseness and play has existed betweenthe two cover portions ofthe binder, This has elicited# cri-ticismfrom the would-be purchaser and requires considerablel explana, tion on'the part of the salesman.
Again, in binders where a screw threaded in an axial bore of the paper-holding post is usedl as the post extension element, an undesirable play'is allowedA to those' sheetswhichengage only the'screw portion of the p'ost;
It is al1-object of this invention to providef means for-folding margins ofthe'fabrie or leather covering'material ove'rthe4 angle back without the necessity of cutting thematerial.
'K It is-aneobject'of this invention-,to prevent play from occurringbetween the two coversectionsV at anyA timeand itis affurther' objectl ofV the` invention' to provide means for preventing any'pl-a-y betweenthe posts andr palper whiehotherwise exists when screw extensions to the post are used.
rEhese and other objects of theinventioi'r will become apparent from the following' specification and the annexed drawing, ,iny
which i i Eig.' .l-'is aperspectiveexploded; ViewY of im roved angle-back binder; v Y ,i-g.; 2 is alongitudinal-section througlhl one end`-;ofthe assembled binder Fig. 8 is a vertical section through the binder on the line -3-3 of Fig. 2;
Fig. 4 is adetail showing of one end of the improved binder bar; and
Fig. 5 illustrates the same bar. with the fabric properly folded over into place.
With reference to Fig. 1, the lower cover section, generally `indicated by 10, bears an angle binder bar 11 on which are carried the two paper-holding posts 12 and 13.A The posts are provided with axial bores into which `The upper cover', generally indicated byV l 15, carries an angle"binde'r'b'arV 17. This bar' carriesia paper-holdingA dummy post 18 at anintermediate position. The post 18 is solid and non-extensible. The binder bar 1 7 is provided with apertures 19 and 21 which give clearance to the heads of the screws 14 andil. Along the upper surface of the binder bar 17 ispl'acedk a locking bar 22 which is slidably" held in place by means of therivets 23 and the elongated slots 2e. Keyhole like apertures 2'5 in the locli'ngbar allowl the heads" 4of tlie'screws lflad' 15 to: protrude therethrough and when the bar 22 is pushed home, the restricted' portion of the apertures engages witl'rthe' shank ofthe screws', thus locking-'the binder. ,Y 1 l Y Withr referenceto' F 2, thepost 18 is subs ta'ntially equ'al'in diamete'rto the lower see` tions' of Vthe post-:51,12 and 131 The holes 8l, 31, provided in the paper, are substantially equal to the diameter of the posts. the upper binder bar is not in place, it is evideii'ttha't there will be considerable play allowed to theV- uppermost sheets, sinceth'e paper sheetsisy removed-f. y
It: i's desirable` that' the; le'ri-gt'l'i of the post 18 shall equal that of the Afixed portieri of the posts 12 andlnn It' should, in any case, equal the permissible extension given 'bythe screws' ll'and'I 15:v To' makel the' insertion `of new sheets' easy and td holdfthe sheets which must'be' removedfor th'is'o'pera'tion in proper order`,the-paper divider 30' is employed." By providingzftlie separator b'ar or paper dividerv 'whichl bears; the sleeves 32,32, and al cle'a'rance hole 33,*the upper portion` offthe binder is always held'- rigidly whethery the binder be full ofpapzerfsheets or not: ln .this case, the ldiameter of the posts 12 and' 13is reduced sufficiently topf allow them to' telescope within, the sleei'fefs`I l32 and they outside `diameter ofA When y these substantially equals the diameter of the movement between the two halves of the binder after the locking bar 22 is pushed home. y. i., l .v
71th referenceto F 1g. t, which is a general showing of the ends of either the bindery bar 17 or the binder bar 11, it will be seen 1 that the bar is provided Vwith a slot 26 cut r along its apex inwardly from the end. 'Ihe covering which is understood may be .of leather, fabric, or other suitable flexible substance, is indicated at l27. A'Ihe marginal strip of the fabric may be turned over upon itself to form a hem and secured in its foldedover'condition with anv interposed reinforcing sheet if a stiff cover is desired, or without such sheet if a flexible cover is desired. In Fig.' 5 the presence of the enclosed reinforcing sheet is indicated merely by the thickness given to the cover. Thestrp 28 along. the transverse margin of the cover may then be folded back and affixed either to the fabric or the reinforcing member without the` necessity of cutting he 'selvage or margin which otherwise would'be necessary to give.
clearance to the-binder web of the binder bar. The longitudinal margin 29 is then folded along the back web of the binder bar, as shown in F 5. For the purpose of clarity, the fabric covering which usually enclos'es the metal is not indicated on these figures. Y
With reference to Figs.v 1 and 5, itwill be seen that the cover is hinged parallel and immediately adjacent to the apex yof the binder bar. `Heretofore when the material was cut, the constant working of the hinge caused fraying, Weakness andr bad appearance at the o very point at .which it was necessary to have the greateststrength.
It will be noticed that the present construction materially increases the strength of the fabric, leather` or other material which is in the hinge.
I claim as my invention: y
1. In an angle back binder, a cover comprising a sheet of flexible material, an angle e binder bar affixed to the sheet adjacent and parallel 'to a longitudinal edge thereof, the marginal Zone of the sheet being folded over and made fast to the inner surface thereof, said binder bar having a slot in theapex thereof adjacent eachendtogive clearance to the folded transverse margins of the sheet. 2. A. binder bar for an angle back loose leaf binder comprising a member angular in jcrosssection andhaving a slot extending inwardly from the ends along Vthe apex thereof and the aperture' and" to ft Y @lst-.1y within it whereby playv between the parts of the binder is eliminated. V l Y 4. In a loose leaf binder, a binder bar, p'aper-holdingposts mounted on the bar each 'having an axial bore and a headed screw therein to form a Vpost extensionV member'of reduced diameter, 'a separator' bar bearingV sleeves adapted to fito-ver the postsl and hav;V

5. In a loose leaf binder of the angle back type, an angle bar having a slot at either end thereofv extending inwardly along the apex of the bar, a flexible' co-verattached vto, the'bar adj acentpto said.V apex and havingrinturne'd hem portions extending through Athe slots, and a plurality of paper-holding posts mounted onthebar.4
` 6. Ina loose leaf binder', an angle bar, a sheet ofilexible covering material attached to the'bar adjacent the apex thereof and having inturned side hem yportions"-'p`assing through slotscut along theapex'of the bar at the ends thereof. l Y
v 7nlnankangle-back binder,v afco'ver coinprising afsheet of' reinforcing material, a sheet offlexible covering material extending beyond the reinforcing sheet-on all of its margins, and an angle binder baran end margin of the flexible material being folded overthe bar whereby the bar and thereinforcing sheet are, secured together, side margins ofthe flexible materialbeing folded over andmade fast to theinner surface ofthe reinforcing sheet, and the apex of the binder bar being slotted adJacent each end to give clearance tothe folded side margins of the'sheetofr flexible. maferial, l -`..jz1; l vIn testimony whereof'I' affix lmy signature.
