LOOSE-LEAF BINDER. I

Specification of Letters Patent.- Patented July 19, 191() Application filed epril 28, 190B. Serial R0. 429,594.

To a wh m i m y onc n:

Be it known that I, Gnoncn HEATH ROBINSON, a subject of the King of Great Britain, residing at Crouch End, London,

England, have invented a certain new and l usetul Improvement in Loose-Leaf Binders,

of which ,the following is a full, clear, and

exact description, such 'as will enable vothers skilled in the art to whichit appertains to make and use the same:

, This invention relates broadly to devices known as temporary or loose leaf binders,-

but in ,a more intense aspect it proposes a selt-contained device haying a series of posts rigidly rising from an inner face of a cover thereof, and so deyisedthat a plurality of loose leaves may/be accumulated thereon,

and, when desired, be removeden bloc therefrom, while at-the same time drawing a brndmg cord through the apertures in a manner enabling a permanentbinding to be obtained by a simple tying voperation.

This invention accordingly has in view,

" among other objects, a loose leaf binder which may be conveniently used as a means for receiving and retaining an accumulation of sheets, and inwhich the free ends of one or more of the' fixed binding posts may be releasably engaged with a removable cover, and in which certain of said ends are also adapted for taking hold of a binding cord whereby it may be properly drawn through the apertures when the sheets are removed. en bloc from said binder softhat the free" ends of the cordwill be in a condition for tying to permanently bind the sheets together. 1 i

- In general, the object of this invention is to devise a temporary binder of the nature disclosed which, from the standpoint of practical usage, will be possessed of a high degree of serviceabilityand ease of op eration, and which,structurally considered, will be of the greatest possible simplicity and strength, being composed of but few parts, all of which are so formed as to be: capable of being manufactured at a. low

cost.

Other parts will be in part obvious from the annexed drawings and in partpointed out hereinafter.

In order that this invention may -tr atin what similar .to' 1,

of accumulated? leavesfremoved e'n'f bloc cover and rise or e be the d more readily understood, drawings illusone of the" many possible forms vt-hereo are appended as a part of ,this disclosure, ,and as will be readily perceived by those skilled in the; art, other modified forms will be immediately apparent or easily deducible from this disclosure, and accord-' ingly are .to be regarded as being within the intended scope of the annexed claims. In such drawings like characters of reference denote corresponding parts throughout all the views of which Figure lis a perspective view of a loose leaf binder embodying my invention, the

parts being shown in their openedout re- 'ilation preparatory for jthreading a bindin cord through the free ends of theffixe posts of the binder. Fi 1; 2 is a view'somehut showing the set from the binder, and illustrating as man- .Illi in 'Whichthe binding cord ';is handled by the above named posts.

Continuing now by 'way of a more detailed descriptiom with sucli occasional refto'afclear comprehensionof this invention, A indicates a suitable holder for the leaves.

Each holder comprises an intermediate section or baclcl to the longitudinal edges of which are hinged, or otherwise flexibly secured, a pair of covers 2 and 3." It will, of course, be understood that "one of these covers may be regarded as the top cover, and the other as the bottom cover, as thecase may be,,and in accordance with good practice these covers may and faced with good wearing material. On one ,of these covers, as forexalnple, from Y the'cover indicated by 3, I have arranged a plurality of guides or binding posts, which posts are solid spring therefrom in 'alinement with and adjacent its line of hinge with the back 1 While I do not assign any particular number of post-s as being absolutely essential to the series'of posts contemplated by my invention, it may nevertheless be observed that I ordinarily prefer to use three equispaced posts, as shown by the drawings; I have not only employed these posts as a convenient meansfor receiving from tune to tune and retaining together in bookj like form a plurality of sheets, but I 'have also so formed these fixed posts "that they-may, on the one hand", serve 'to detachably retain the opposite cover in place, and,

on the other hand, constitute a means ,;n-

and rigidly secured to such' .erence to the drawings as may be'conducive bemade relatively stitt To these. ends,

' mediate loop and then tie the ends'together' to form a neatly bound bundle of papers.

I' have provided the posts a with means for detachably engaging with and also with. means the opposite cover,

eyeletsfor taking hold such as hooks and of the bindingcord and drawing the same through the apertures in the leaves. 'Thus,

-the two end posts lia-11d 5 have their upper extremities provided with loo s "or eyelets- 6 andJZ, respectively,

and a so provided with; annular recesses or ,necks' 8' and 9, whose function is'to engage with'a digitally which preferably is "operated interlocking means on the opposite flap'or cover 2,. The intermediatepost 10,

iQfrgimthe two-above-ment-ioned posts, also purposes. For this purpose,

rises rigidly fromfthe flap or cover 3, .and at its upper end provides a means -..'grasping and releasing an intermediate for easily oring the upper extremity of the intermediate post '10 is preferably provided with a hook 11, which, as will be perceived, is not i only capable of easily takmg hold ofa middle portlon of the bindtion of a cord'to-be employed for'bin ing cord, but equally permits of an immeindicated by Fig. 2. I B denotes a. series diate disengagement ;wh'en such cord has been drawn throu h into the relation shown by Fig. 2. It wi l,o'f course, be perceived thatin lieu of the closed eyelets 6 and 7 in the" end posts of the series, hooks or other retaining. 'exp'edients may be adopted,: but

from many aspectsthe eyelet is thebetter form, inasmuch as it is inherently strong and the'free ends-of the cord may be readily withdrawn therefrom when in the position of marginally apertured leaves which are from time to time built up or accumulated onthe above-mew tioned guiding or binding posts, prepara- -tory' to being finally removed en bloc in registry. To facilitate this latter operation, I have devised'a registeringdevice-which consists of an elongated bar 12 having apertures 13,14 and 15 for receiving the posts 4, 10 and 5 respectively. Rigidly secured to such apertured bar 12, way between each pair'of apertures, I have arrangedposts 16 and 17, which posts are adapted for beinginserted intovthe corresponding apertures provided by the leaves of the set B for the purpose of retaining the same in registry during removal. As will be seen, when this has been done, these posts pass through wholly, or in a large part, through the set of leaves and form a registry insuring means, thereby promotin and facilitating the withdrawing of such Ieaves ing the covers together arranged equi-distant place against withdrawal.

"and serviceable,

'ing cord, I have succeeded in preferably mid- 1 more of such ends through the middle loop,

which willhavebeen disengaged from the hook 11 on the middle post 10;

,To enable the binder to bemore conveniently used from day to day when it is receivingits accumulation of leaves, I have deviseda simple means of detachably holdthrough the instrumentalityof the end posts 4 and 5, This meansforms a gripping device D arrangedon the cover or flap 2. This device comprises an elongated plate 18 which is slidably mounted in such cover, as by means of a top plate'19. An upturned element 20 of the elongated plate 18 protrudes at the end of the same, and provides a finger piece',thereby enabling, the elongated plate to be digitallyipositioned to be en aged or disengaged, as the case may be, wit the bindingposts. This latter operation may be, accomplished through the enlarged head receiving apertures 21 having narrow slots '22 extending therefrom in the sliding plate 18. The overlying plate will also have an entering aperture 23. Now, the extremities of the binding posts may be inserted through the apertures, 23 in the cover late, then. into theapertures 21 in the sllding plate18, andpby ldngitudinally translat- .lng such plate 18 by means of the finger grip 20, the neck will enter the elongated slots which will securely hold the same in A-spring 24, may also be used as a means of retaining the sliding plate in its locking position.

It will thus be erceived that I have devised a binder wel adapted to achieve the several objects and ends of my invention. The device as a whole is simple, compact and moreover, requires a minimum amount of manipulation or dexterity on the part of the operator. By using the solid binding posts also as a means for threading the leaves together with bind.- obtaining a very strong and efi'ective construction in a particular which otherwise would be characterized by the essential and inherent structural weakness. v

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language used in'the a pair of covers, a plurality of posts rigidly secured to one of said covers, certain of said posts having their free ends provided with means for temporarily retaining a binding cord, a sliding member mounted in sai other cover having a pluralityof apertures of a binding bination, a holder having a palr 0 formed therein, the .cord retaining means of one'or more ofsaid posts being provided with portions adapted to engage a similar number of apertures in said sliding member.
