BINDER.

Application filed March 23, 1923. Serial No. 627,003.

To all 1071 0722. it may concern:

Be it known that I, CHARLES H. FRANZ, Jr., a citizen of theUnited States, and resident of Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented certain new and useful Improvements in Binders; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to binders and is particularly directed to loose leaf binders, which are adapted to be carried from place to place.

In binders such as those used by traveling salesmen, it has been customary to provide substantial covers which fully protected the front and back of the pages but ex posed the margins to dust and rain. This necessitated either the complete wrapping of the catalogue or book or the provision of a separate case therefor, but even with these precautions the leaves soon become unsightly from the soot and dirt which rapidly accumulated upon such leaves.

This invention is designed to overcome the above noted defects, and objects of such invention are, therefore, to provide a binder for loose leaf books, such as catalogues, which will not only form the backs but will also fully and adequately protect all por tions of the book from dust or rain, which will accommodate a large number of loose leaves, which permits their ready removal or insertion, and which may be readily opened out flat to fully display any desired sheets and which may be instantly closed to thereby completely house the sheets.

An embodiment of the invention is shown in the accompanying drawings, in Which- Figure 1 is a perspective view showing the binder and the enclosed sheets opened out flat.

Figure 2 is a perspective view showing the device in the closed position.

Figure 3 is a side elevation partly in section, to illustrate the interior construction, such figure corresponding roughly to a section on the line 33 of Figure 2.

Figure 4c is a sectional view on the line 4-4 of Figure 3.

The binder comprises a pair of binding strips 1 and 2 of reinforced and sturdy construction, which are adapted to receive between them the loose sheets 3. A pair of back plates 4 and 5 extend inwardly from the binding strips and are overlapped and slidably related, as may be seen from Figures l and 3. Any desired means may be employed for holding the binding strips in engagement with the leaves, for instance, an expansion bolt 6 and a sleeve 6 may be employed, such sleeve being conveniently attached to the back plate 5, as illustrated in the drawings. These expansion bolts and associated sleeves may extend through apertures in the sheets in the usual. manner.

A pair of reinforced covers, 7 and 8, are provided and are attached to the correspond ing binding strips by means of flexible hinges, as indicated at- 9 and 10, preferably formed from leather or similar easily manipulated material. A convenient Way of attaching these strips to the cover is illustrated in Figure 3, from which it will be seen that the strips are received within an inner ply of the cover and the remaining plies thereof and stitched in position. This construction forms a waterproof joint between the covers and the binding strips. Each of the covers is provided with a U-shaped strap member, having its legs 11 stitched across the face of the cover, as illus trated in Figures 2 and 3, to form a secure attachment for the curved portion 12 thereof, which portion is utilized to form acomposite handle. In this manner not only are the covers further reinforced, but the strain from the handles is distributed over a material portion of the covers and is not calized at any one point. If desired, the curved handle portions 12 may have reenforcing rods 13, (see Figure 3), to stilfen them. A strap 1% may be attached to one of the handle portions, and may be provided with snap fasteners so that it may be wrapped completely around both of the portions of the composite handle and snapped in place to form a convertible handle and a simple means for holding the covers in closed position.

In order to protect the marginal edges of the book from dirt, dust and rain, inwardly directed flanges are provided along the three free margins of the covers. The flange 15 of the cover 8 may be overlapped by the flange 16 of the cover 7, and it is to be noted that these flanges overlap a ma terial distance so as to form an effective and serviceable protecting joint to prevent entrance of harmful matter. It is to be noted that the flanges continue in unbroken formation completely around the three edges of the cover and are free from the back plates 4 and 5 to permit the complete opening up of the book, as illustrated in Figure 1. When, however, the book is closed, the flanges and 16 overlap the, end margins of the back plates, as may be I seen from Figures 2 and 4, thereby com Lat pletely protecting the leaves from the on trance of rain or dust.

It will be. seen that a binder has been provided which is adapted to accommodate anydesired number of leaves, and which is at all times securely attached to the leaves. This provides a binder which in effect forms a portion of the composite book.

.It is further to be noted that the overlapping back plates and the'overlapping flanges '15 and 16 completely house the leaves, and

Y the free edges of said covers to completely house thevleaves when the book is closed,

and a pair of strap handles secured to said covers and adapted to form a composite handle when 'said book is closed.

2'. A binder for loose leaves comprising binding strips, adjustable means connecting said strips and binding the leaves between them, a pair of overlapping back members extending from said strips, relatively stiif covers hingedly joined to said strips, and flanges extending inwardly from the free edges of said covers and telescopically related to completely house the leaves when saidv covers are closed. 7 I

3. A binder for loose leaves comprising a pair of binding strips adapted to hold the leaves between them, adjustablebolts connecting said strips, a pair of slidably related overlapping back plates carried by said strips, a pair of reenforced covers joined to said strips by flexible material,

inwardly directed telescopic flanges carried by said covers and adapted to overlap the ends of the back plates, and a U-shaped strap for each cover having its legs secured across the face of its corresponding cover and having its curved portion projecting therefrom.

In testimony that I claim the foregoing I have thereunto set my hand at Milwaukee, in the county of Milwaukee, and State of Wisconsin. CHARLES 'H. FRANZ, J R.
