T0 all 'whom it may concern:

Be it known that l, JOHN iVnisnuon, a citizen of the United States, residing at New York city, Manhattan borough, county and State of New York, have invented certain new and useful Improvements in Boekbinders, of which the following is a clear, full, and exact description.

This invention relates to bookebinders, one of the objects being to provide a device which is simple in construction and effective in operation.

A further object of my improved bookbinder is to provide a laterally adjustable frame whereby a book of any desired thickness can be built up by adding more leaves. The elements which go to form my improved book-binder are constituted to obviate the necessity of perforating the leaves of the book and yet to hold the leaves firmlyin position.

Further advantages will be hereinafter presented.

To these and other ends which will hereinafter appear, my invention comprises the novel features of improvement and combination and arrangement of parts which I will now proceed to describe and finally claim, reference being had to the accompanying drawings, forming part hereof, wherein# Figure 1 illustrates a perspective view of my improved book-binder, the leaves being removed; Fig. 2 is a detail top-plan view of my improved book-binder, the cover being removed and a portion of the leaves shown; Fig. 3 is a detail sectional view, taken on a line a-a in Fig. 2, and shows the retaining bars for the leaves in position, Fig. 4 is a erspective view, broken on", of the retaining bar and shows the manner of retainingr the leaves; Fig. 5 is an enlarged cross-sectional detail view of the locking-bar and spring carried thereby; Fig. 6 is an enlarged fragmen tary sectional detail plan view of my improved adjustable frame.

Referring now to the drawings, partieularly to Fig. 1, my improved book-binder comprises the end-members 1 and 2, said end members being composed of the stationary members 8 and 4 (Fig. 2) upon which are mounted laterally adjustable plates 5, 6, 7, and 8. A separator 9, of wood or other material to which the stationary members 3 and 4 are suitably secured, determines the Width of the book. The end members 1 and 2 and the plates 5, (i, 7 and S thereon, together with the separator 9, form the frame or binder for the book. A cover 10 is secured to the separator in the usual manner.

As shown in Fig. 6, the adjustable plates 5, (i, 7 and 8 are secured to the stationary members 3 and 4 by the thumb-nuts 11, which engage threaded studs 12 carried by the members 3 and 4. The plates 5, 6, 7 and 8 are provided with slots 13 through which the studs 12 pass. To steady the plates 5, (i, 7 and S, I have, in this instance, employed steadying pins 14, which project from the members 3 and 4 and enter the slots 13 (see Fig. 1). To the upper end of the plate 5 I pivotally mount a locking-bar 15, as at 16. Near the bottom of the under plates 6 and S, I secure the stationary reach bar 17 (sce Fig. 3). The retaining elements for the leves comprise the bars 18, around which are folded a plurality of leaves 19 to form the book (see Fig. 4), each folded sheet forming two leaves. I can use as many of these groups of leaves as desired. After having made as many groups of leaves as I desire, and in the manner described, I place the groups one upon the other between the end frames 1 and 2, the adjustable plates 5, 6, 7 and S being provided with an inwardly projecting flange 20 which acts to keep the bars 18 from slipping outwardly longitudinally of the book. The bars 1S are a little shorter than the distance between the end frames 1 and 2 which permits of the easy insertion of the bars. The di'll'erenee between the length of the said bars and the width between the members 1 and 2 will not be enough to permit of side lashing of the bars 1S and groups of leaves thereon. After having inserted the bars, the locking-bar 15 is closed and a pin 21 is, in this instance, used to hold the bar 15 closed as shown in Figs. 1 and 2.

To hold the groups down, and to press them firmly together, I mount on the underside of the locking-bar 15 an auxiliary locking element, comprising a leaf-spring 22, which, when the bar 15 is locked, presses upon the top group of leaves. The spring 22 also compensates for the space of a group, should said group be removed for any purpose. In other words I am able to take out a group of leaves or to add a group without affecting the stability of the book, as the said spring 15 will compress, if I add a group, or expand if a group is removed. Therefore,

under these,y two circumstances, the said spring will always act to iirmly press the groups downward and together.

If I desire to increase the capacity of the binder to an extent-greater than can be accomplished by adding one or two groups of leaves as has been described, I loosen the thumb-nuts 11 and draw the adjustable plates and 7 upwardly and push the plates 6 and 8 downwardly to the desired extent, and then tighten the thumb-nuts 1 1, whereby the end frames 1 and 3 are greatly increased in lateral width.v By this means I am able to add several more groups of leaves to the book. The flexible portion 22a of the cover 10 permits the cover to accommodate itself to the increased thickness of the book.

Having now described my invention, what I claim and desire to secure by Letters Patent is:

1. In a book-binder, a binding-frame provided at the ends thereof with laterally adjustable members, and bars carried by said members, one of said bars constituting a locking element.

2. In a book-binder, a binding-frame, laterally adjustable end members carried by said frame, a plurality of independent removable retaining bars, adapted to hold leaves, carried by said frame, and means adapted to hold said bars and the leaves earried thereby, in said frame.

3. A book-binder, comprising a frame, composed of a separator, end members carried by said separator, laterally adjustable plates carried by said end members, a reachbar carried by the lower plates, a pivotally mounted locking-bar carried by the upper plates, andan auxiliary locking element carried by said looking-bar.
