LOOSE-LEAF 3300K OR BINDER.

T 0 a-ZZ whom t may cof/cern Be it known that I, GEORGE ALFRED BEN- Nn'r'r, a subject of the King of England, residing previously at Quatford, Curraweena Road, (iden Huntly, but now at Hillside, 52

` Caroline street, South Yarra, both in the State of Victoria, Commonwealth of Australia, (whose post-oilice address is Hillside, 52 Caroline street, South Yarra, in the State of Victoria, Commonwealth of Australia have invented certain new and useful Improvements in Loose-Leaf Books or Binders, of which the following is a specification.

rl-his invention relates to the class of account or other books having interchangeable leaves and commonly lrnown as loose leaf books or ledgers. The invention is, however directed more particularly to a binder for books of this class in which the two halves or sections of the cover are united by two or more flexible thongs or tapes along which one of the halves or sections is adapted to be drawn to or from the other section by the operation of a screw mechanism located within the movable section of the cover, this mechanism being externally operated by a detachable crank handle or key. The advantages of such books have been proved but the use of the screw mechanism for separating or contracting the two halves of the cover is objectionable both on account of the excessive cost which it entails and also its complexity and liability to derangement. Loose leaf books of a smaller size have also been used in which the two halves of the cover were expanded or contracted along the tapes by hand and locked in desired p0- sitions by means of a ratchet mechanism located within one of the cover sections. This ratchet mechanism is,.however, also open to the objections above Stated and does not allow of a sumciently tight grip on the leaves of the book.

rl`he object of the present invention 1s to eliminate all such winding andv ratchet mechanism and to provide a cheap, simple and eiiicient loose leaf book or binder having all the advantages of the type above mentioned, but at a fraction of its cost. A furtherI object of the invention is to provide the binding bars of the device with rubber or other linings or faeings having recesses or indentations by which a tenacious suction grip is exerted upon the leaves of the boolz. Any loss of power in contracting the binding bars tightly upon the sheets and which might be Specification of Letters Patent. Patented Dec. 28, 1920. Application led April 22, 1919.

tions of the cover separated, portions being broken away for convenience of illustration. The fastening clips which lock the movable section of the cover in pre-determined positions on the flexible tapes are shown in locked position.

Fig. 2 is a longitudinal section of Fig. l

taken in theplane of one of the flexibleV thongs or tapes.

Fig. 8 is a cross section taken on the line A of F ig. l.

Fig. l is a view similar to Fig. 2 but showing thetwo sections of the cover contracted upon a series of leaves or sheets, and the fastening clip in an unlocked position. The dotted lines show how the tape is buckled or looped to provide a grip for the hands when the cover sections arel being drawn together.

Fig. 5 is an enlarged detail view showing one of the binding bars provided with gripping strips having cavities or recesses therein.

Fig. 6 is a view similar to Fig. 5 but showing corrugations in place of the cavities in the gripping strip. j

Fig. 7 is an'enlarged section taken in the plane of the hinges and showing clearly how the leaves are held between the gripping strips. One of the cover sections is shown closed.

Fig. 8 is an enlarged perspective view of portion of a tubular flexible thong or tape which may be converted into a round shape.

Fig. 9 is a cross section on line B Fig. 8. Fig. l0 is a perspective view of a core used to convert the tape seen in Fig. 8 to a round form.

Fig. l1 shows the tape converted into a round form by the insertion of a core.

Fig. l2 is a fragmentary view showing i portion of a leaf having elongated eyelets.

Fig. 12T shows portion of a leaf having round eyelets.

Fig; 1li is a sectional view showing clearly how the flexible tapes may be converted for use with leaves having round eyelets.

On reference to the drawings it will be seen that the numeral 2 indicates the front section of the cover and 3 the back section thereof. Att-ached by suitable hinges ll to the rear edge' oi each cover sec-tion is a wooden or other binding bar 6. rlllhese binding bars are lined on their inner faces with gripping strips 7 or 7 oi rubber, metal or other suitable material. Formed in the gripping strips are a series oi cavities or recesses 8 seen in Fig. 5 or corrugations 9 as seen in Fig. 6. These corrugations do not extend quite to the end ot' the binding bar.

Suitably fixed to one of the binding bars are the inner ends ot two or more flexible thongs or tapes 11. These tapes 1l may be ot leather, fabric or other suitable material and are of a comparatively stili nature. They pass througl'i slots or openings 12 formed in the other binding bar and thence into channels or slideways 13 formed within the section 3 of the cover. Part oi each sli'dewa'y is preferably open as at 16 to enable the tapes to be gripped when the cover sections are being drawn together. Rollers 14 a'nd 15 'are provided to prevent fracture of the cover and enable the-tapes to run freely therein.

Attached to the outer ends of the tapes may be metal or other cross pieces 1'? which run in grooves 25 formed at the sides ci the slideways and retain the ends oi the tapes in position.

Located within recesses 2O formed in the cover section 3 are metal plates 1S Jirom which upstand bearings 19. ln these bearings are mounted the trunnions 21 oic a fastening clip which may comprise a inger piece 22 formed integral with a right angled holdingpiece 23 adapted to engage and lock the tapes as seen in Figs. 1 and 2.

Preferably, but not essentially, the tastening 'clips are 'connected by arms or extensions 24 to a centrally situated catch 26 so that the :operation of said catch simultaneously operates boththe Afastening clips. The catch 26 is adapted to engage a suitable lock 2T which may be 'provided with a key hole 28 or other suitable means whereby the fastening clips -inay `be locked in a closed position to prevent unauthorized insertion or removal of leaves from the book.

The thongs or tapes seen in Figs. 1 to d are in theform shown, particularly adapted for use with leaves 30 having elongated eyelets 29 as in Fig. 12. In some cases, however the leaves are provided with round eyelets such as v3-1 (F ig. 13). The eyelets in each -c'as'e being 'entered by `gullets 32. ln Fig. 8

it will be V'seen that the vsides o' tubular tapeare stitched together by a series of longitudinal stitches 33. Formed Vat `'cf'invenient intervals in one side of the tubular tapeare holes or slits 34 to admit cores 35.

Should leaves having round gullets such as 31 be used the tapes may be converted to suit same by cutting the stitches 33 between two or more of the holes 34 and introducing one or more of the cores 35 through the holes or slits and into the tape which then assumes a round form as seen in Figs. 11 and 1e. The number of the cores used will depend upon the number of sheets to be inserted'in the book as will be fully under` stood on reference to Fig. 13 of the drawings.

ln use the leaves are inserted in the usual manner by entering the thongs or tapes through the gullets 32. Should it be `desired to expand the two sections of the cover Afor the insertion or removal of leaves. the catch 26 is disengaged from the lock 27' and lifted thereby causing the fastening clips to be lifted also and releasing the thongs or tapes. rlhe two cover sections are now simply drawn apart by holding the section 2 or the leaves resting thereon with one hand and pulling the section 3 outwardly along the tapes with the other. The leaves may now be removed or introduced as desired. To contract the halves of the cover and lock the leaves in place. the outer ends of the tapes aremoved toward the fastening clips so that a loop is formed inthe tape as shown in dotted lines in Fig. e. By grasping this protruding` part of the tapes with the hands and pulling toward the right in the drawings while the cover section 3 is held stationary the two sections ot the cover are drawn' together until the gripping strips are pressed tightly against the leaves. The fastening clips are now closed and the catch 23 snapped home and if desired locked by a key or the like inserted in the hole 28. The slack outer ends of the tapes may be then pushed outwardly along the slideways so that they lie Hat therein as seen in Jfull lines in Fig. 4.

The recesses or corrugations in the gripping strips create a suction against the leaves and cause them to be firmly gripped between the binding bars.

vIn the draw-ings an open backed binder has been shown but-it will be obvious that if desired a leather `or other flexible back may bridge the space between the binding bars to cover and protect the back edges-of the leaves. This flexible back may be adapted to telescope Vwith-in the two sides of the cover in the manner employed in certain known types 01:' loose leaf books.

It will be obvious that various modifica-- tions or alterations may be made in the construction above described without `d'departing V`trom the nature, spirit or scope of the 4invention and it is intended and desired that the foregoing description shall be vinterpreted as covering such legitimate departures.

What I do claim as my invention, and desire to secure by Letters Patent, is

l. A loose leaf binder comprising two cover sections, flexible means for uniting said sections together on which flexible means one of said sections is slidably mounted by means of channels or slideways in said slidable section to accommodate the flexible means, and rollers on the slidable cover sec*- tion over which the flexible means pass.

2. A loose leaf binder comprising two cover sections, flexible means for uniting said sections together on which flexible means one of said sections is slidably mounted by means of channels or slideways in said slidable section to accommodate the flexible means, rollers on the slidable cover section over which the liexible means pass, and cross pieces on the ends of the flexible means mounted to run in grooves in the slidable cover section.

3. A loose leaf binder comprising two cover sections, a binding bar hinged to each of said cover sections, one of said bars having a slot, flexible means secured Yat one end to one binding bar and passing through the slot in the other bar and thence through channels in the cover section to which said other bar is hinged, the said binding bars having their inner faces lined with resilient material provided with recesses.
