FREDERICK GRIMME, OF CHICAGO, ILLINOIS.

BINDER-FRAME Specification of Letters Patent.

Patented May 25, 1909.

Application filed June 22, 1908. Serial No. 439,742.

To all whom it may concern:

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

This invention relates to loose leaf binder frames for holding ledger and other leaves, circulars, catalogues, etc., and its object is to provide a frame of simple and inexpensive construction adapted to receive and hold the leaves secure and evenly and permit them to be easily inserted or removed.

Further objects of the invention are to provide a binder frame with a round back; to cause the stub ends of the leaves to spring up like a spring back book and the leaves to lie flat when the book is opened; and to provide simple means for adjusting the book.

l/Vith these and other objects in view the invention consists of certain improvements on the frame disclosed by my Letters Patent No. 796,322 dated August 1, 1905 and which will be fully pointed out hereinafter in the detail description of the accompanying drawings, in which Figure 1 is a plan view of the binder frame. Fig. 2 is a sectional view on the line 22 of Fig. 1. Fig. 3 is an enlarged detail sectional view. Fig. 4 is an end view showing the locking mechanism. Fig. 5 is a sectional view on the line 5-5 of Fig. 4. Fig. 6 is a detail sectional view of the rubber head.

In the drawings, 7 designates the back of the book which is made of resilient material in the shape of a round-back book. The covers 8 are hinged to the back in any manner familiar to book binders but preferably by means of the covering 9 which may be made in one piece to cover the back and cover boards, as shown in Fig. 2.

A center plate 10 having upturned ends 10 is arranged centrally within the back and a plurality of yielding spring steel connections 11 are adjusted to said center plate. Clamping plates 12 having inwardly projecting edges 12 to engage the leaves (not shown) are mounted on the ends of the yielding connections. The clamping plates are bent to form a socket 13 to receive a pivot pin 13 which rests in said socket and engages hinge members 14 fastened to the covers and projecting outward from the covers through openings 15 in the clamping plates. Thus the covers are hinged to the frame and the clamping plate constitutes one member or leaf of the hinge and the parts 14, which are fastened to the cover board, constitute the other member of the hinge. These hinge members 14, project through the openings 15 in the clamping plates to aline with the socket grooves 13 so that the pivot pins 13 may be readily inserted or removed.

Two rollers 16 of the same diameter are mounted in parallel relation in the ends of the center plate and are provided with intermeshing gears 17 so that they will rotate together. One of the rollers is provided with an extension 18 to receive a key. Tapes 19 are fastened at their ends to the rollers and they pass over guide rollers 20 which are mounted on pins 20 arranged in socket 21 in theclamping plates.

It will be observed that the clamping plate is bent to form the socket 13 on one side to receive the pivot pin 13 and also to form the socket 21 on the other side to receive the guide roller pin 20. The spring connections 11 are extended up to overlap the pins 20 (Fig. 3).

The tapes are preferably fastened to the rollers in some manner interiorly thereof to avoid providing a projection on the surface of the roller which might have a tendency to make the rollers wind unevenly. I have shown one way of accomplishing this result in the drawings in which the rollers are provided with longitudinal slots 22, the ends of the tape being inserted in said slots, after which the roller is clamped upon the ends of the tape by a hammer blow or pressure.

The rollers are locked in adjusted position by a locking dog 23 which engages a ratchet wheel 24 on one of the rollers. A spring 25 operates on the locking dog to hold it in engagement with the ratchet wheel and in the particular construction illustrated in the drawings the dog is located on one side of the end 10 of the center plate and the spring 25 on the other side. The dog is provided with a projection 26 which extends through a slot 27 in said plate to be engaged by the spring 25. The dog is released from engagement with the ratchet wheel by a cam 28 carried by a push bar 29 which is supported in brackets 30, 3.0. on. the end 1'0.. This camis normally held out of operative engagement with the dog by a spring which may be in thevform; of a coil spring 31 located on the push bar between the end 10 and the bracket 30 and bearing against the cam 28 (Fig. 5).

may provide heads 32 made of rubber or other suitable material at the ends of the back 7. These heads are shown in Fig. 1 and in broken lines in Fig. 2 and a detail section isshown in Fig, 6 The heads are fastened to the back of the book, at the ends thereof, in any suitable manner, and they preferably overlap. the same to form the projections 33 on which the book may rest. These heads are divided into sections so that the back of the book may be extended or contracted as required.

Braces 3 4;, preferably of the same material as the connections 11, are, fastened to the clampingplates adjacent to said connections and extend approximately to the center plate. These braces tend to push the middle part of the back down as the edges are drawn together when the rollers are turned to wind the tapes thereon.

I" may use a leaf made as disclosed in my Letters Patent No. 767 ,940 dated Aug. 16 1904 or any other leaf which is or be adapted to this binder.

My improved binder frame is light in weight but strong and substantial: in con.- struction and comparatively inexpensive to manufacture. Each frame is capable of. adjustment to hold a greater or less number of leaves and; at all times the binder will hold the leaves regardless of the number evenly and properly in place. The construction is such that when the book is opened the stub end will spring up like a spring back book andthe leaves will lie flat and close together at the. points therein without spreading and exposing the tapes in the manner set forth and described niorefully in my Patent No. 796,322 hereinbefore referredto. When it is desired to insert or remove a leaf or leaves thelocking dog is released by pushing the push bar in and then the clamping plates may be spread apart as far. as desired. After the leaf is inserted or removed the rollers are woundup, to tighten the clamping plates on the stub ofthe book by applying a key to the projection 18. The hinge members 14 are made of metal in. any suitable manner and are located on the inner sides of the covers so that the outer side of the covers will be perfectly fiat. A removable canvas cover may be used on the book and this cover will conform to the back of the book whether. the back is extended or contracted to receive a large number or a few leaves. I may use aremovable key, as heretofore mentioned, or a per-v manently attached key on the projection1'8.
