. LOOSE-LEAF-BINDER FRAME.

SPECIFICATION forming part of Letters Patent No. 770,749, dated September 27, 1904.

Application filed February 28, 1903. Serial No. 145,574. (No model.)

To (If/ZZ whorn/ t may concern.-

Be it known that I, FREDERICK GRIMME, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Loose-Leaf-Binder Frames, of which the following is a specification.

` This invention relates to novel improvements in loose-leaf-binder frames of the type now employed extensively for holding ledger and other sheets for bookkeeping purposes and to some extent for holding circulars, catalogues, &c.

The object of the invention is to provide a binder-frame of simple and inexpensive construction which will hold the inserted sheets securely in place and permit of their ready insertion and removal.

A further object is to apply to and embody in a binder-frame of this character the principle of a spring-back book, so that when the book is opened the back of the leaves will be sprung up in the same'manner as a springback-bound book and the leaves caused to lie, to all intents and purposes, flat and smooth, and a still further object is to dispense with the ordinary prong and post leaf-rests and utilize the tension of springs for the purpose of securing and holding the leaves in proper position in the frame.

With these and other ends in view, which will be fully pointed out hereinafter, I have illustrated the invention in the accompanying drawings, in which-` Figure l is a planview showing a binder comprising two sections without any leaves therein and in closed position. Fig. Qisasimilar view showing the binder opened. Fig. 3 is a transverse sectional view showing the binder provided with a number of leaves and opened. Fig. 4 is a longitudinal sectional view through one section of the binder. Fig. 5 is a transverse sectional view illustrating another form in which the binder may be embodied. Fig. 6 isa detail View showing how the leaves may be slotted. Fig. 7 is a plan view of a binder made in three sections. Fig. 8 is a longitudinal sectional view of the binder shown in Fig. 7 I Fig. 9 is an end view of the binder shown in Fig. 7.

Referring to the drawings, in which like numerals of reference indicate corresponding vparts in the several figures, Figs. 1 to 5 illustrate my invention embodied in a frame comprising two sections 10 11, which can be cast or stamped out of sheet metal and are provided with sides 12 and ends 13. The back of one section, as 11, is extended, as indicated by 14, beneath the other section and is arranged to slide in ways formed by the inwardly-turned flanges 13 on the other section, Fig. 4. This construction provides for enlarging the binder by extending the sections without leaving an opening in the back, and the parts may be constructed with a View to providing for receiving a greater or less number of sheets from time to time and within such limits as may be predetermined. Spring-rollers 15 are suitably mounted in the two sections, and tapes 16 are connected at their ends in any suitable manner thereto and travel over guides 17 on the sides of the sections above the rollers. The spring -rollers may be constructed and arranged in many di`erent ways, and I do not restrict myself to the particular construction illustrated in the drawings or to any other one form. I have Ashown a hollow roller provided at one end with a stub-axle 18, havingabearing in the plate 19, fastened to the end of the section or made integral therewith. The axle 2O at the other end of the roller is arranged in a slotted bearing 21 in a similar plate 22 and is of a form, preferably flat, which will engage the walls of the slot and prevent it turning with the roller. A spring 23 is fastened at one end to the inner end of this iiat axle and at its other end it is fastened to the roller.

It is obvious that springs of various kinds may be employed and in many diiferent ways for attaining the ends sought by my invention, and for this reason I have chosen to illustrate a spring-roller of very simple and wellknown construction to better explain the invention and indicate its simplicity and the inexpensive character of its construction.

The tapes may be made of leather, parchment, fabric, or other material of a flexible nature, which will answer the purposes of-the invention, and the tensionof the springs in the rollers will, preferably, be adjusted to correspond, so as to wind up the tape to an equal extent on each roller.

The guides may be made in many different ways, but I prefer to use antifriction-rollers, as shown in the drawings.

The leaves 24 are provided with elongated openings 25 to receive the tapes, and the leaves are provided with slots 26, extending from the edge of the leaf to the opening to permit the leaf to be readily arranged on the tape in the proper manner. I may employ two or more tapes, and of course the leaves will be provided with a corresponding number of openings to receive them. I also prefer to scarf the stub end of the leaves in any suitable way to make them thinner than the body of the leaf, so that they will be more flexible at the stub end and fold over on the line of the slots in the manner shown in Fig. 3 and lie flat on 'the covers 27, which are hinged to the sections in any suitable manner. The slots will to a very large extent promote the flexibility of the leaves at the stub end thereof; but I prefer to reduce the thickness of the stub ends, as shown in Fig. 6, and which can be accomplished by means of cutters or by a sandpapering machine or in any suitable way.

I do not claim herein the leaf as an independent articleof manufacture, as this forms the subject-matter of my application Serial No. 170,637, filed August 24, 1903.

In Fig. 5 I have shown a binder constructed to receive and hold a comparatively few number of leaves, but adapted to be extended to hold a greater number, the sections being curved to accommodate the rollers and the tapes being wound thereon in a direction opposite to that shown in Fig. 3.

In Figs. 7 to 9 I have shown the invention embodied in a binder comprising three sections 28 29 30, the two sections 28 and 30 being constructed in all material respects substantially similar to the sections lO and 1l of the binder shown in Figs. l to 5 and arranged to slide within the upturned ends 29 of the middle section and guided by the plates 3l. For the purpose of securing the three sections together and preventing their becoming disconnected and for the further purpose of insuring that both of the side sections 28 and 30 shall move to a corresponding degree I provide a pair of spring-plates 32, which are connected at or about their middle to the side sections 28 30. These plates are connected together at their ends by pins 33, which are provided with enlarged heads 34, arranged to travel in the undercut slot 35 in the rib 36 on the middle section 29 of the binder. These spring-plates thus connected constitute, in effect, a fusiform spring-metal band, which is preferably of elliptic shape and connected at the middle of each plate to the side sections and guided at the contracted ends on the middle section. It follows, therefore, that both side sections must move to the same extent relatively to the back section, and thus the relative position of the sections is constantly maintained This controlling-spring device and thus adapt it not only for the purposes to. which these binders have already been largely.

used in connection with bookkeeping, but also for holding circulars, price-lists, and other information which merchants, manufacturers, brokers, and others may send to their customers and correspondents from time to time.

I contemplate that these binders can be made and sold at such low cost that merchants and others will send them out to their customers, and instead of printing complete cata-.

logues, which are necessarily reprinted entire at frequent intervals, will send instead loose sheets or sections, which can be tem-l porarily or permanently bound in these binders as they are received and taken out when substitutes come tol hand. This will will enable the merchants to keep their customers posted closely to date and 'at comparatively small expense and avoid the trouble and annoyance which frequently follows from ,changesin prices after catalogues have been distributed. Furthermore, it will be observed that my binder is constructed and arranged toI receive and hold the ledger or other leaves for use in bookkeeping and that these leaves will lie flat whenthe binder is opened, Fig. 3, so that entries can be readily made thereon. While this is of special importance in this particular use of a binder, it is also very desii-able when the binder is used for catalogue purposes, so that the letter-press can be easily read. Ledger-leaves are usually made of comparatively thick and heavy paper, and for this reason I prefer to scarf or thin the stub ends thereof as heretofore described; but for catalogue purposes this will probably not be necessary, because thinner andmore flexible paper is generally used.

The tension of the roller-springs should be sufficient to cause the tapes to hold the side sections of the binder tightly clamped on the leaves when the book is closed and yet permit the book to open readily in the manner shown in Fig. 3 without tearing the leaves.

, It will be observed by reference to Fig. 3 thatv IOO IIO

the stubs of the leaves will spring up in a manner similar to a spring-back book when the book is opened instead of being held in rigid position down between the side sections of the binder. The tapes thus hold the stub ends of the leaves in the arc of a circle and securely in place, so that the leaves will liein flat position. When the book is closed, the edges are all smooth, and the leaves can be readily fingered toopen the book .at a particular place. Scaring the stub ends of the leaves also reduces the thickness oi' the stub end of the book and enables the spring-rollers to hold the leaves tightly and compactly.

To prevent the leaves adjacent to the covers from becoming worn by the guide-rollers or otherwise, I may providel plates or strips 37, (shown in Figs. 3, 4,) which are slotted to receive the tapes and are located thereon between the top and bottom leaves of the book and the guide-rollers. Instead of using loose plates I may provide inwardly-turned ianges 37', integral with the side sections and located above the guide-rollers, as shown in Fig. The iiat axle 20 will be held in place in any suitable manner, and for this purpose a wedge 38 may be driven into the slot above the aXle.-

My invention can be embodied in binderframes which vary greatly in size, shape, and details oi' construction from that herein shown and described, and I do not wish to be understood as limiting the scope of my invention to any particular construction, but reserve the right to embody the invention in any form which will come within its spirit and scope.

rI`he invention can be embodied in a two orthree section back, as described; but it will be observed that the two side sections are the important parts, and it is immaterial, so far as the invention is concerned, whether there be an intermediate middle section or not, and the claims will be so read and understood.

Without limiting myself to the exact construction and arrangement of .parts herein shown and described, whatI claim, and desire to secure by Letters Patent, is-

l. A binder for loose sheets comprising a frame, spring-rollers carried by the frame, and tapes attached at their ends to said spring-rollers and carrying the sheets.

2. A binder for loose sheets comprising a frame consisting of telescopic sections, a pair of spring-rollers mounted in the frame, and

tapes attached at their ends to said spring-rollers and carrying the sheets.

3'. A binder for loose sheets comprising a frame, spring-rollers carried by the frame, guides located above the rollers adjacent to the top of the frame, and tapes traveling over said guides and having their ends attached to said rollers.

4. A binder-frame for loose sheets comprising two telescopic sections, a spring-roller carried by each section, guides on each section above the roller, and tapes traveling over the guides with their ends attached to the rollers.

5.
