LOOSE-LEAF BINDER.I

To all whom it* frrtayfco'nc'ervr;

Be it known that I, S. PROUD'- iiT, Jr., a citizen of theuUnited' States, re'- sidingl at Chicago, in the county' of- Cook' and State of Illinois, have invented a' new' and useful Loose-Leaf- B'inder, of which the following 1s a' specica tion;

My invention relatesv tob1nders having one or more. leaf holding strips to which the leaves. are removably secured, afnd the ob- ]ects of my invention are first, to have a tree and complete action of the covers; seeond, to afford aflexible andl substantial fla-t o )enin bindinf`- third. to' rovide a con venient means for attachingand detaching' leaves; fourth, to-provide a novel means for adjusting the leaf holding bands; fifth, to

make a cheap and durable construction and other objects to' become apparent from the description to follow.

rFlic binder comprises twocovers preferably hinged a shortdist-ance from their binding edge to a back, and' leaf holding bands connected lio-the covers' and adjusted thereon in a novel manner. rllhe covers are provided with eyes near their binding edge' ,ricalh the rod, bythe swinging of the cover when the binder is closed.

-The leaves are attac-hed to the leaf hold ing bands by suitable notches in their binding'cdge. These notches are so laced that n. Ashort stubA endl of each leaf wi l lie below the bands when the leaves are in position.

"llfiicn the binder is closed, that. portion of the binding' edge of the covers extending be'- yond the rods 'which holdl the bands will be approximately parallel .with the leaves.

A"When the binder is opened thebindinffedge of the covers will swing against the ieaves, thus pressing them more firmly when the binder i's opened than when it is closed. The bands are exible, preferably, Hat' .and of resilient. material and are adjustably attached tothe covers in a manner hereinafter described.

To. describe my invention so 'that others versed in the art to which 1t pertains mayl Specification of. Letters Patent.

Figure l, is aplan view of a binder ernbody'ing my invention with both covers open and all the leaves removed. Fig. 2, is a cross section on line 2 2 of Fig. l, but With the covers closed; Fig. 3, is a similar view' Withthecovers open; Fig.' 4' is an enlarged detail view; Fig. 5, is a' perspective of aA catch used on the binder; Figs. Gand 7 are perspectives ofV sheet metal fastening plates usedon" the binder; Fig. 8, isa modification and Fig. 9,

is a portion' of the binding edge of ale-af Ashowing the aperture for the leaf holding band.

Similar reference characters refer to similar partsthroughout the several views.

The covers 5 and 6 are Hexibly connected tothe back 7 A andE arel preferably provided at their binding edgesv with metal plates 5" and 6 having a portion curled baelr` into the eyes 8 and 9 through which are placed' the rods 10 and' 11 respectively. The' plates 57 and G may be extended' to form the c0mplete covers and' any suitable material may be used,l although metal. The eyes 8 and 9 are positioned to act as guides tothe leaf holding bands 12', which are passed between the rods 10, l'l, andthe metal plates 5 and 6 andv arethen connected to the covers, so' that the connected ends swing with the' covers, and the intermediateI portion lying'between thel rods I- prefer to use sheetv l0 and l1` may be deflected from the covers by the swinging of the covers when closing' The rods l0 and 1'1 are not the binder. y necessarily round' but I prefer t-o make' them so to provide asmooth round surface for `the bands to bend back and' -forth upon at this point.

A portionl3', ofzthe plates on which the' eyes 8 andv 9are formed extends beyond the eyes S and 9; This extension 13, lies approxim'ately parallel with the leaves When the covers are in a closed position, the binding force 0f the covers against'the leaves being exertedA at or near the point Where the leaf' holding strips emerge from t'he opening'underthe rods 10 and l'l, as seen in Fig. 2. When the covers are openedY the' extension 1'3" swings around against the leaves,

the binding' force then being exerted' Where ,the extremity of' the extension' 13l en ages the leaves as seen in Figi 3". This resu ts in the leavesV being 'somewhat more' loosely' ilo bound when the covers are closed than when they are opened. Heretofore in books of this descriptioxl the greatest strain on the leaf holding bands occurred when the covers were closed, but by the use of my invention as described above, the strain on the bands is relieved when the covers are closed, because the length of the intermediate or leaf holding portion of the band is then 1ncreased by the sum of the distances from the rods 10 and 11 to the ends of the extensions 13, thus equalizing the tension on the bands when the covers are opened and closed, and permitting free and complete action of the covers.

Then the covers of the binder are opened the leaf holding intermediate portions of the bands 12 are thrown up away from the back 7 thus permitting the leaves to lie fiat; when the vcovers are closed the bands recede into the back. A

I prefer to make a slight bend inward in the extension 13 which serves to give the bands 12 a greater upward direction when the covers are opened. yThis bend may be made so that the binding edge of the covers will engage the leaves either above -or below the line of the bands 12.v p

The extension 13 may extend along the entire binding edge of the covers 5 and 6, or along a part of the binding edge only, without changing its action on the leaves. I prefer to make that part of the extension 13 under'the bands 12 somewhat shorter than lthe remainder of the extension, thus leaving .a little space between the extremity of 13 at this point and the leaves, as this serves to relieve the strainon the bands 12 when the covers are swung.

Each leaf holding band 12 has one end adjustably secured to lcover 6 by means of a small metallic extension or lug 14 fastened to cover 6. The lug 14 can be formed on a part of the cover, but I prefer to make it 'on a separate plate 15, towhich is also loosely attached the small rod 16 which serves to hold the band 12 close to plate 15 with ythe lug 14 extending through one of the series of openings in said band. The rod 16 is bent around the eyelet 17 to swing about the same loosely and when in position to hold the band 12 its free end is sprung under the hook 18 formed on plate 15. The relative positions of the eyelet 17, the lug 14 and the hook 18 is such that the rod 1'6 is held under the hook 18 by the lug 14. The plate 15 is'secured to the cover by clenching down the rongs 15a; The other end of each leaf hollding band 12 is ivotally connected to the center strand o a U 'shaped bail 19 which has its extremities pivotally secured to the cover 5, by the eye plates 20 in such manner as to swing the center strand toward and away from the binding edge of the cover. Obviously the l.clenched to secure it to the said cover.

catch 21 is pivoted to a small plate 21a,

binding edge of the cover.- To normally re- 7 tain the bail 19 in a position farthest ter strand is sprung under the catch 21 secured to cover 5. It is understood that the pivoted member above described is not necessarily a U shaped bail, but may be of any form permitting pivotal connection with the cover 5 and pivotal connection with the band 12 at a point. not in line with the pivotal connections with the cover 5, so that 'the pivotally connected end of the band 12 may be swung toward and away from the binding'edge of the cover 5.

, The eyed plate 20, which is shown in detail in Fig. 6, is provided with a plurality of prongs 20a which piereethe cover 5 and are The which is secured to cover 5 in a similar manner z'. e. by prongs.` The catch 21 has formed thereon a hook 2lb, in which the bail 19 normally rests. It will be noted as seen in Fig. 5, that the hook 211 is slightly nearer the cover than the pivot on which the catch 21 swings, so that the pull exerted by the bands 12 will tend to hold the catch21 with its free end against the cover 5.

l/Vhen itis' desired to remove a leaf from the binder it is necessary'to have considerable slack in the bands' 12 between the covers which is provided by swinging the bail 19 toward the binding edge of the cover. It may be stated here that each leaf as shown in Fig. 9, Vis providedl with suitable shaped notches in its binding edge to receive each band 12 in the usual manner.

To remove 'or insert a leaf the bail 19 is first released from the catch 21 and then the cover 5 vis pulled away from the leaves in the binder, which is accomplished by holding the leaves or preferably the fly leaf in one hand and the cover 5 in the other hand and pulling apart. By thus manipulating the binder the leaves orat least some of them are liable t0 be torn attheir bindingI from. the binding edge of the cover the cenedge* I therefore provide a heavy fly leaf y 22 adjacent to each cover and provide slots 23 in the binding edges of said leaves for the reception of the leaf holding bands l2.

In the binding edge of each iiy leaf 22 a strip 21 preferably of sheet metal is mounted, having suitable perforations for the. bands 12 to pass through. The fly leaves :22 serve to preventvabrasion of theleaves in the binder since they are interposed between the covers and the leaves and are'also used as a stra, to be pulled upon instead of the leaves wien the cover is separated from the sheets by swinging the bail 19.

In Fig. 8, is shown a niodication in small hooks 27`provided on cover 6.' The hooks as will be seen are alternately faced in opposite directions, so that the red 2G will be held under said hooks 27 and serve to hold the bands 1Q nextto cover 6 with the lug 14 extending through one of the series of openings in the band 12.
