LOOSE-LEAF BOOK.

Specification of Letters Patent.

Patented Dec. 28, 1909.

Application led August 4, 1906. Serial No. 329,144.

-useful Improvements in Loose-Leaf Books,

of which the following is a specification, reference being had to the accompanying drawings, forming part of the same.

Figure l, is a perspective view of a book embodying my invention: Fig. 2, is a side elevation of such a book with the leaves in the position they assume when the book is taken in hand for the purpose of finding a given interior page thereof; Fig. 3, is a vertical, longitudinal, sectional view, on line 3 3 of Iiig. l, but showing a portion only of the book; Fig. l, is a plan view of the plate piece, and the binders, showing the closing arches of the binders, in the positions they assume when they are opened for the reception or removal' of leaves.

My invention relates to loose-leaf books and it consists in the manner in which and means by which the leaves are secured in place.

In the book shown, 5, 5, are the covers of the book, G, is the back, and 7, are the usual flexible hinges of the back, which permit the front or back cover to be raised. 8, is a metal strip, usually about an inch or less in width, and nearly as long as the cover is from top to bottom. It is connected to the cover or the back, usually at the joint 7, between the bottom cover and the back, by a flexible hinge 9, preferably of cloth. Seated in the plate or strip 8, and secured thereto are posts l0, -11 &c., and I prefer to have at least four (t) and as many more couples as may be required to rrnly hold the leaves. If the book is very long, there may be six (G) or eight (8) or even more. The rear posts l0, are preferably hollow, and the front posts 11, may be. If not hollow, they are preferably recessed for a distance from theirl upper ends fora purpose to be described. Flat arches or staples 12, are provided, the rear legs of which are seated and secured in the hollow posts 10, and the front legs of which are adapted to seat themselves in the recesses in the upper ends of posts 11, the dimensions of the staple being such as to permit such adjustment. The particular means by which the staples are secured are not important, provided they are left free to turn and to slide up and down to a limited degree. Y

Surrounding the rear leg of the staples, preferably within the hollow post l0, and secured to staple l2, and to post l0, or plate S, are springs la. I have shown them as coil springs, coiled around a reduced por.- tion of staple 12, and soldered to it and to t-he post l0. The purpose of the springs is twofold, first to hold the staple down, so that its front leg shall remain in therecess vof post ll, though permitting it to be raised sufficiently to clear the top of post ll, when desired; and second, to throw the staple around when it is raised out of the recess in post ll, that it may be out of the way when leaves are to be removed from or placed upon the posts ll.

The operation, (manifest from a view of the drawings) is as follows: )Vith the staples in the positions shown in Fig. 4, the loose sheets, perforated to it over posts ll, are placed thereon. rIhen the staples are lifted and swung around till their short legs register with the recesses in posts ll, when the springs 14, if permitted, will draw the staples down and force their ends into said recesses, thus locking the sheets in place.

The punched holes in the sheets are, preferably, located a distance from the edge, a little less than half that from posts l0, to posts 1l, the result of which is that any por tion of the leaves may, at will, be lthrown over so that they are held by posts 10, the balance being-still held by post ll, and each portion will lie entirely flat, and remain so, so that one may refer to a page without holding it open and may write upon the entire surface of the side which is upper without the necessity of leaving the margin, which all ordinarily bound sheets must have, and without the inconvenience which is ever pres ent when a sheet, that is curved or bent, is to be written upon. This facility, as will be noted, is equally present as to each side of the sheet, for if the desire be to write upon the side which is now the under side, it is merely necessary to turn the leaf over till it is held by the other post, when said other side will be uppermost. It will then lie flat and may be written upon with the saine facility which attended writing upon the face that was previously uppermost. The reading of what may have been written upon either side is equally convenient. Not only so, but the turning of the pages, to find llO a given one, is particularly easy: The plate carrying the posts and leaves being hinged at one edge only to the hinge corner of the cover, may be readily turned up to the position of Fig. 2, when the leaves may be easily and rapidly passed under the thumb for examination.

If an additional leaf is needed, for instance, one supplemental to one already present, and for that reason or any other it is desirable that it should fol-low a given page, all that is necessary is to turn to the page to be succeeded by the new, throw it and the preceding leaves over upon posts l0,

raise the staples, (which will instantly spring out of the way, to the positions of Fig. 4L), place the new page, replace the staples, and the new leaf is immediately secured in proper' position. To prevent the withdrawal of the staple to such a degree as to unduly strain the spring, a bead may be turned in the tube of posts l0, as shown in Fig. 8, which will effectively prevent such excessive movement.

A small pocket may be formed at the back of the cover to receive card bearing index letters or any other designation desired.

This book may be used to take the place of a card index, the leaves answering to the cards, and bearing such index numbers, colors or marks as are common in a set of index cards. They are much more readily handled than a drawer full of cards, and, being thinner, occupy much less space, are much more readily consulted, as already shown, and are much less expensive, being at the saine time much more readily transferred from one place to another and susceptible of being kept in any desk or any table or other place without the necessity for a specially constructed receptacle, as required for cards. They are also equally adapted for use with large sheets of any and every character.

that I claim as my invention and desire to secure by Letters Patent, is

I. In a loose-leaf book, the combination {a4/issie of two posts secured to the cover, each provided with a hollow space, a staple with legs of a cover, a plate secured to said cover by A an edge hinge, two posts secured to said plate each provided with a hollow space, a staple with legs adapted to enter and rest in l said hollow spaces in the posts, and a spring connected to the post and to the staple, with its stress opposed to the lifting of the staple, and to the alineinent of the staple in place from one post to the other, all substantially as set forth.

3. In a loose-leaf book, a cover with two sides, and a back joined thereto by two joints, a plate secured to said cover, at one joint, by an edge hinge, a hollow post secured to said plate, a second post with a socket recess at its upper end, secured to said plate in line with but at a distance from the lirst post, a flat topped staple provided with two legs, one of which short and is adapted to rest removably in the socket recess of the second post and the second of which is adapted to rest in and turn within the first post, and a spring surrounding said second leg, vithin the hollow of the first post, and secured to the post and the leg, with its stress opposed to the lifting of the staple and to the alineinent of the staple, all substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses, this 31st day of July, 1906.
