Doesn-LEAF BINDER.

vApplication, mea,- Mareh 15, 192.6. serial No. 94,71?.

such sheets are being collected, that they,

4may be'temporarily bound until the assembly for a volume is completed. It is a primary object and purposeof the present in# vention to provide a binder for record sheets and the like which may be used tobind the same temporarily in order thatl other sheets may be added until the desired number a volume is attained, whereupon covers may be added to 'the temporary binder Vand Vsealed in place in such a manner that thev covers cannot be removed nor thepart-s of the temporary binder reached, so that .by the addition of such covers and theirper` manent connection a permanent binding of the sheets in a volume is secured.

A' further object of the invention is to provide a binder of the-class described which is very simple in construction, economical to manufacture and durable and efficient in its operation. The means whereby these 'ends are attainedas well as many others not at this time Vspecifically stated, is lfully dis:- closed in the following description taken in connection with the accompanying drawings, `in which Fig. l is a perspective view illustrating a number of sheets, the method Vused for temporarily binding the same andthe parts which go to make up said binder, the same being shown in -separated condition.

Fig'. 2 is a similar view showingrthe parts together and in position tofeffect a temporary bindingofthesheets. Fig. 3 is a fragmentary section illustrating slightly different form of ybinding means.

fFig'. 4 is a fragmentary perspective 'view showing the cover used and applied to the temporary binder to make Athe same permanent.

5 is a fragmentaryenlarged trans- 2'verse section through the back portion of a volume permanently bound together, the

1n hinges.

Fig. 6 is a lperspective view of one of the leaf holding members used, and

Fig. 7- is arear elevationl ofA a. volume permanently bound, the connecting back between the two covers being shown in section' Y Aso as to disclose the rear end ofthe volume which is ordinarily covered by saidback.

VLike referencev characters refer to like parts in the d ifl"erent ,igures in the drawlngs. f The sheets which are to be bound together are indicated at l and at theirback edges are provided with apluralityY of apertures or notches'2 `of the. form shown, the same being4 adapted to. have the leaf holding members pass therethrough.'k Thev leaves may be placed, `one over the other, thebottom'leaf, atvits back edge, lying against the lower binding bar-which is of angle' forni having a bottom flange?)- and a back vertical flange 4. The bottom fiang'e' at vits for v` ward edge is formed with `a lplurality of spaced apart rolls 5, the same, as are used Said Vvbottom flange' 3 also, at 'spaced apart pointsin its length,v has slotsl 6 cut therethrough for the passage yof lower leaf holding membersA 7 upwardly through saidopenings. The members 7 vrare' of flat f stock narrowed at their upperportionsv to make the tongues andat their lower ends being turned at right angles making the flanges 9 which bear against thelower sides of the lower flange 3 -of thebottom binding `bar. YThe leaves, when passed over the Aleaf holding member 7 are held by said v'members as they tures 2, asis obvious.

hinge Vrolls 51. 'Also the vupper flange 3l i has Aa `number of spaced-.apart slots vGlfcut pass through the notchesorfaper- When a n umber'of the leaves havebeen f i put 'together' to form the ,leaf body an upper binder bar is Aapplied to. the leaves.'

therethrough, one for each ofthe leaf mem'-v bers, tongues 8 extending upwardly through saidrslots G1.- Companion leafmembers 1 0 of flat form areVv4` inserted downwardly through the/slots 6l, each of said members 1@ at its upper end being wth'a flange 11 having a slot 12 therein through v`which the vtongue y8I of the' lower associated leaf member 7 may pass. As thusapplied to the leaf body the tongues 8 may be bent backvvardly, as shown in Fig.v2, to effectv the securing ofthe leaves or sheetsjtogether,

it being evident that Whenever desired the tongues maybe bent back to vertical position :so rthat the upper clamping bar niayV be removed for the additionvof other sheets or leaves. V' i Inl Fig. 3 a modified form of structure forefi'ecting the temporarily binding of sheetsor Aleaves sshovvn, the leaf members 71and`10 being supplanted by a U-shaped `Wire having a bottom portion 13 and vertical spaced apart legs 14'Which may'pass through suitable openings in the lianges 3 and 31 of the lower and upper binding bars.

lThe projecting upper ends of the legs l14 are bent inwardlytoward each other, as indicated at 15,'and into slots cut intoflange 31 of the upper binding bar. In all.cases, irrespective of how the actual leaf vengaging members are made, the horizontal {ianges 3' and'l of thejtWo binding bars are prol videdv at theirforwar'd edges, vin front of Where the leaf holding members pass through said flanges, With the' hinge rolls 5 vand 51', Vthe purpose vof which will later ner that they are permanently bound `and no'further addition to or removal from the volume can `take place. K

The cover consists of tivo leaves 16 con? nectedA at their rear edges by the usual back To each `of the covers 16`on their inner sides and near: their back portionsfhinge plates 18 are permanently secured by rivets or otherwise,r the same, at their rear' edges being' formed with spaced yapart hinge rolls 19 which are so' located with reference to each rotherfthat the hinge rolls and 5l on the flanges'fand 81 of the'binding barsma'y'be Vreceived in the'spaces between said hinge rolls 1,9 and hinge rods, shown at 21, pass through the alined openings made by therolls 5l and Y 19`and 5'1 and`19. One oftheiparts 5 and 51 atv one end, of the binding bars", is equipped Witha short headed pin 2O which is driven intoz the end of the rolls 5' and 51 so ras `to be permanently secured.V AIn fact,r to

make the connection permanent and one which cannot be disturbed it is our practice to solder' such headed pins 20 in place. These pins 20 are best shown in Fig. 7. The

.tance from theoutcr ends of the outermost rolls v5 Amd 51 le n`f i1` ig,a'spa'ceV shoivnat 22 in Figi.` This makes the rods 211naccessible so'fthat the same cannot be removed and, in practice, We flatten, upset or enlarge the ends of the rods 21 thereby making theml fit l tightlyi` into the rolls so vthat When driven fully into place the Asame are very scct'ire'ly' held by friction at the enlarged end against any possibility. offdlongitudinal movement.'k y' f Y i It Will be noted that by sition of the hinges the yupperv rearwardly bent 'ends' of the tongues 8 are inaccessible so that the temporary binder which is made before the covers arer applied, becomes a permanent binder' WithV the' application of thecovers in" the'manner outlined;v The onlyway that the upper ends of'the tongues 8 Vor., if the modification shown in Fig. dis use`d,'the upper ends 15 of the legs 14, can

be raised,y is by destruction ofthe back 17 i Awhich, of course, involves destruction of Vthe binding of the book..y The' construction 'Shown' and described is especially adapted reason of the pfofor khandling public records required in perj.v

marient bindings whichVH cannot be bound loosely, subject as they might bev to removal under such circumstances.V At the same time the actual binder' which is used ico in the finished book serves, AWithout change,

the purpose of a temporary binder during the' time that the volume" is being made up. y .The construction outlined has beenfound very practical and eihcient. Many variay vtions in minor detail ofk construction'may be resorted to Without departing from the invention which is defi-ned in the appended claims and We consider ourselves-entitled to all forms of structure which come Within the scope of said claims.
