TTNTTE ST FRANK E. HOUSE-I, OF XVINTI-IROIP, MASSACHUSETTS.

LOOSE-LEAF BOOK.

Application filed May 12, 1915.

' To all whom it may concern:

Be it known that I, FRANK E. HoUsH, citizen of the United States, residing. at Winthrop, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Loose-Leaf Books, of which the following is a specification.

My invention relates to loose leaf books and is for an improvement in the construction of books such as are shown and described in United States Letters Patent granted to me May 7, 1912, No. 1,025, l68.

A book made as shown and described in the patent referred to holds the leaves or sheets in proper order so long as the covers are securely fastened to the binding strips and the full thickness of the stack of leaves is maintained therein, but it has been found that when thin paper is used the sheets curl or are easily bent at the binding edges particularly at the slotted portions thereof and therefore are likely to slip out of engagement with the binding strip.

The particular object of the present invention is to provide a loose leaf book so constructed that it will securely hold thin leaves or sheets, prevent the curling or bending of the binding edges, permit the removal of some of the sheets without liability of others being freed accidentally, and having a cover which can be opened out fiat thus exposing for use practically all of the surface of the top sheet.

1 In the accompanying drawings: Figure 1 is a partial plan view of my improved book showing the same in open position; Fig. 2 is a side view of the book with the covers in closed position; Fig. 3 is an enlarged section on the line 33 of Fig. 1; Fig. 4: is a perspective view of the back cover plate of the book shown in Fig. 1 and two of the binding strips used therewith; Fig. 5 is a perspective view of one of the binding strips hereinafter described; Fig. 6 is a longitudinal sectional view of one form of binding strip; Fig. 7 is a longitudinal sectional view of another form of binding strip.

Having reference to the drawings, A represents the rear side cover of my improved book and B the front side cover thereof, the back of the book, B, being hinged at b to the rear side cover A and at b to the front cover B. The cover A comprises preferably a sheet metal plateb inclosed by a cloth or paper covering, 21 integral with Specification of Letters Patent.

the covering of sections B and B. The plate, 6 is provided near one end thereof with a pair of hooks, 6 formed by cutting and bending portions of the plate, 6 and these hooks are adapted to engage binding strips, 0. The strips C are formed with an obllque tongue adapted to fit into the correspondingly oblique slots cut in the end of the stack of leaves, 1). Each binding strip, C, is preferably made from a single piece of sheet metal cut and bent so as to comprise a body portion, a, and two sides or wings, 0 the tongue, 0, being an inwardly bent portion integral with the body portlon, 0. After the binding strips, C, have been fitted into and upon the stack of leaves, D, each strip is then engaged with its respective retaining hook, Z2 by sliding one of the sides or wings, 0 thereof into position under the hook, 6

In the present invention the side pieces or wings, c of the binding strip extend be yond the tongue, 0, so that the binding strip engages and holds together the leaves of the stack at both sides of the slot occupied by the tongue, 0. This makes it practical to use much thinner leaves or sheets than heretofore, thereby increasing the capacity of the book and at the same time allowing the withdrawal of one or more of the sheets, by pulling endwise thereon, without disturbing the others in the stack. This characteristic provides a construction that is particularly adapted to sales books since while the leaves are normally held securely in place the top leaf or sheet after it has been written upon can be separately pulled out of the book without danger of accidentally removing the ones below it, thus avoiding the necessity of providing perforated. sheets as is now com mon. Another advantage is that the sheets when so detached from the order book may be filed for future reference in another binder of like construction. as by the rcmoval in the manner described there is no mutilation of the sheet itself.

To hold the binding strip, C, against sliding sidewise relatively to the hooks, b and working out of engagement with the slots of the leaves, D. I form the plate. 6 with abutment lugs, 6 bent up at right angles to said plate, one at each side of the stack. D. These lugs serve to prevent sidewise movement of the stack of leaves and binding strips when the same are engaged by the lugs Z2.

The tongue, 0, of the binding strips, C, is formed by slitting the body portion, transversely near one end thereof and longituolinally near each side wing, 0 part way toward the opposite end of the strip and bending obliquely inward the tongue or flap thus produced. This mode of construction provides a cross bar, 0 connecting the ends of the binding strip which gives rigidity to the strip, assists in positioning the strip on the stack of leaves and prevents the curling or bending of the leaves at the corners thereof and at the edges of the slots. In Fig. 7 I have shown a binding strip made from a single piece of metal bent to form two sides or wings slitted at one end and near each side thereof for a portion of its length, thus providing the tongue, 0*, which is bent obliquely inward. Obviously this form of binding strip requires less metal than the binding strip, C, above described.

I claim 1. A loose-leaf book comprising a stack of leaves; a cover; hooks projecting from said cover; binding strips adapted to engage with said hooks, each binding strip comprising a body havlng a back adapted to fit against the edge of the stack of leaves, and

cover; binding strips adapted to engage said hooks, each binding strip comprising a body having a back adapted to fit against the edge of the stack of leaves and formed with an oblique tongue adapted to fit into a slot in the stack of leaves and having wings perpendicular to the back of the strip at each side of said tongue extending lengthwise of the body beyond the tongue in both directions so as to hold the leaves of the stack against displacement at both sides of the slot.

3. A loose-leaf book comprising a stack of leaves; a cover provided with hooks; binding strips adapted to engage with said hooks and provided with oblique tongues adapted to be engaged with correspondingly oblique slots provided in the stack of leaves, the sides of each strip being extended lengthwise of the latter beyond the tongue so as to overlie the stack at both sides of the slot engaged by said tongue; and a pair of abutments at each side of the stack to prevent lengthwise sliding movement of the binding strips relatively to said hooks.

4. As a new article of manufacture, a binding strip consisting of a top and two depending sides; and a tongue connected with the top near its center so formed as to lie obliquely between the sides of the strip.

Signed by me at Boston, Mass, this 28th day of April 1915.
