To all 'whom it may 'concern-:-

Be it VknownV that I, BRADFORD WEBSTER, a citizen of the United States, residin at Louisville county of Jefferson, and tate of Kentuc y, have invented a new and useful Book, of which the following is a specification.

My invention relates to books in which leaves are loosely adjusted and bound on leaf-penetrating members; and the objects ofV my invention are to provide a simpler and more effective structure in the binder; and toprovide loosely attachable means for internal compression binding. I attainpthese objects by the mechanism illustrated in the accompanying drawing, in which Figurel is an elevation of the binder as seen from the back of the book when laid flat, the right half of the figure showing a vertical longitudinal section through the center; Fig. 2, a plan of the lower base on the line 2-2 0f cross-section of the guide-post lock on the line 3*?) of Fig.V 1; Fig. 4, an end elevation, partly in section, of the binder on the line 4-4 of Fig. 1; Fig. 5, an enlarged sectional view of the first form of guide-post; Fig. 6, an enlarged section of Vthe vend of a guidepost of the second form; Fig. 7, an enlarged plan in part section of the locking mechanism,us1ng the guide-post shown in Fig. 6; and Fig. 8, a, perspective of a dummy pad. Similar letters refer to similar parts throughout the several views. f

The binder consists of tw'o binding parts or bases, in each of which is set one ormore leaf-retaining members and each ofwhich is provided with openings for admitting freely the leaf-retaining "members of the other part'to any extent, so that the bases may be pushed against each other. The leaf-retaining members of one part have means near their free ends and as far along their length as is desired for admitting an engaging element of the other part: This engaging element of the other part 1s combined W1th` the base and the leaf-retaining members which are set therein.

A represents the base of the binding part which contains the locking slide C. The slide C is held in this casing by a cap-bar B. In the cap-bar B are set the leaf-retaining members F and F, which penetrate the ln-y side face ofthe casing A and are set tightly therein soas to support the cap-bar B andV Fig. 1; Fig. 3a horizontal the casing A in their relative positions. TheJ locking slide C may be shorter than the casing A so as not to reach the leaf-retainlug member F. The leaf-retaining member also penetrates a slot X in the locking slide C and holds it slidably against removal from the casing` A. i y

The slide C has openings Z, the edges'of which converge to allow the free passage of the lockable leaf-retaining members-E and E of the other binding part when the slide is pulled out; and these same edges are adapted to engage the leaf-retaining members E and E when the slide is pushed in.. The Vcap-bar Band the casing A have holes suitably placed to admit freely the' leaf-retaining members E and E. In the lfirst form of my invention, kthe lockable leaf-retaining members E'and E have annular teeth near their free ends which are beveled downward, and the' en'-V i gaging edges of the locking slide C are beveled upward, so that thelockingslide will not only lock the leaf-retaining members, but the leaf-retaining members will lock theslide not only by friction,but also by ('zenterwardv pressure of a beveled surface von'each ,leafretaining member pressing against a dorre-`v sponding beveled surface in the4 locking slide. This tends to hold thelocking slide in position when the leaferetaining mem? bers E and E are pulleddown by'the.eX-' pansive spring of the leaves and binder. This form is illustrated in Fig. 5.A 'i l Another form of leaf-retaining member and locking slide is illustrated in Figs. 6 and The inside engaging edges of theflocking slide C are so shaped that'the leaf-retaining members E and E will pass freely'through the slide when the slide C is pulled out'.

When the slide C is pushed in, a narrow portion of each opening through which the members E and E have entered, will enter the leaf-retaining membersv at points of small dia1neter,and the circular end por-V tions of the slots will engirdlev the leaf-retaining members more than half way around at points where said leaf-retainingfmembers' are of slightly larger diameter.v Whenv the locking slide C has been pushed' inY so that the engaging edge surrounds the'V post E at one ofits smallest points, the eX-K pansive spring of the leaves, the spring inf,y the binder, or the elastic dummy fpads, pushes the locking slide C upon the post so that the engaging edge engages the post at a slightly higher point than where it entered it and at a point where the diameter of the post is slightly larger, so that the engaging edge engages the post at this point about three-fourths of the way around it, locking not only the post but also the locking slide itself until the bookl is compressed and the locking slide forced back downward to a point on the post where the post is of smaller diameter.

In the middle of the lower base I is fixed a spring M, 'adjusted to press a flat bar N toward the upper base of the binder, thus holding the leaves under contractive spring pressure. The bar N has tour holes so that it will move freely up and down the four posts E, F, E', and F, and loe held in alinement by them. Y

'Ihe covers K and K should have their outer surfaces even with the upper and lower surfaces respectively of the bases I and A, so that there will be no improper projection when the book is placed upon the shelves in a library. The back of the book is in two thin stiff sections, crossing each other slightly when the book is open to its full eX- panded thickness and capable of sliding by each other.y

To provide loosely attachable, cumulative means for internal compression binding and spring binding, I employ the dummy pad I), shown in Fig. 8. This pad has holes to admit the leaf-retaining members et the binder.' To give it an elastic binding edge, its binding edge may consist of a strip ot aerated spongy rubber R, or other springyielding substance. The expanded thickness of the strip R may be greater than the thickness of the remainder of the pad I), so that when it is compressed the outer partot' the book will not be thicker than the book at the binding edge. It it is desirable, by reason of the spring M or the thickness of the bases A or I, to iill up some space so as to make the covers even with the back of the book, the pad P can be made thicker than the elastic strip R.

I do not limit myself to the exact form in which my invention is herein disclosed.
