Applicatioiifiled April 14, 1924. Serial No. 706,397.

provements in aRing-Book Ooverjand I hereby declare that the following is full, clear, and exact description of the same, reference being had' to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification. i

This invention relates to a ring book for containing loose leaves and concerns itself witha structure consisting ofa two piece cover united in a novel way.

The object of the invention seeks to reduce the usual waste in the manufacture of such ring books in the provision of a structure in which two pieces of leather or the like may be utilized to form the cover thus avoiding the waste flowing from the use of a single integral piece.

The invention comprises the. novel structure and combinations hereinafter described and more particularly pointed out and defined in the appended claims.

In the accompanying drawings which illustrate a preferred embodiment of this invention and in which similar reference numerals refer to similar features in the different views;

Figure 1 is a perspective View of the interior of a partially formed ring book.

Figure 2 is an enlarged fragmentary in terior perspective view of apartially formed ring book illustrating certain features.

Figure 3 is an interiorplan View of the completed ring book.

Figure 4; is an enlarged sectional and fragmentary view through the two piece cover.

Figure 5 is a sectional view upon the line 5-5 of Fig. 2.

Figure 6 is an enlarged sectional view upon the line 6-6 of Fig. 3. p

Figure 7 is an enlarged sectional View upon the line 7-4? of Fig. 3. 1

Figure 8 is an enlarged fragmentary sectional view of a slightly modified form of structure showing how the back is sewed in.

Figure 9 is a fragmentary sectional view of the modified form shown in Figure 8 with the covers in proper position.

Referring to Figs. 1 toT-of the drawing; it will be observed that the ring book cover consists oftwo separate pieces 1 and 2 of I flexible material such as leather which have their innerniar 'ifns scar-fed as indicated at A narrow strip of leather 4 is sewed to each scarfed margin to unite the two pieces so that the scarfed portions will overlap. The seams are adjacent the outer edge of each scarfed portion whereby the soarfed portions are free to be. folded up or back as shown in Fig. 2. This narrow strip, which may be termed aback piece hasend flaps 5 which are adapted to befolded inwardly and engag z ed overtangs '6 upon the concave bottom or anchor plate 7 embedded beneath the scarfcd portions 3. I

Instead of sewing the back piece to the covers 1 and 2 as shown in Fig. 4, a differ entform of back piece l as shown in Fig. 8 may be employed. This back piece 4- is bent into U-form and sewed between the covers as shown in Fig. 8. Then when the covers are brought into the same lane as shown in Fig. 9, the seams will be folded under the back piece into concealed positions.

In assembling the ring book, the anchor plate 7 is positioned beneath the scarfed margins 3 which are then folded thereover as shown in Fig. 1. The ends flaps 5 of the back piece are then superposed upon the scarfed portions 3 and anchored to the tangs 6 by engaging suitable slits made therein. The leaf holding mechanism which in the present instance is shown as of the toggle plat-e type is then anchored to the anchor plate 7. This leaf holding mechanism which is old and well known consists of a pair of bowed plates 8 and 9 which have overlapping margins and which confine the toggle plates 10 therebetween. The lower bowed plate 9 is provided with suitable slots to receive the tangs 6 which are then crimped thereover asshown in Fig. 7, whereby all the parts are securely clamped together.

It will be appreciated that the feature of using a two piece cover as herein described makes it possible to utilize a large amount of the leather that has heretofore gone to Waste, so that a substantial economy is effected.

I am aware that many changes may be made, and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and 1 therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim as my invention;

1. In a ring book, a pair offlexible covers having their inner margins scarfed and overlapping, a back piece secured to said scarfed margins and having end flaps, an anchor plate positioned beneath said scarfed portions, said end flaps being folded over and secured to said anchor plate, andleatholding mechanism anchored to saidanchor plat-e.

2. In a ring book, a two-piece cover, the adjacent margins of said; pieces "being scarfed, and a back piece uniting said margins in overlapping relation, said back piece having end. flaps adapted for securing an anchor plate upon said back piece.

3. In a ring book, a pair of flexible cover members having their adjacent margins scar-fed and arranged in overlapping relation, and a back member having its margins respectivelysecured to the difierent cover members beyond the overlapping portions for uniting the same, said back piece having end flaps.

4. Ina ring book, a pair of cover members having their ad acent margins scarred and arranged rmvoverlapping relat on, and a back piece having a body portion and inturned margins secured to said cover "members "for uniting the same, the securing means of said inturned'margins being concealed beneath the said body portion.

5. In a device of the character described, a pair of separate cover members having their inner margins arranged in overlapping relation, and a back piece having asbody portion and inturned margins, said inturned marginsbeing respectively secured to said cover members, and the securing means being concealed by said body portion.

(3. In a ring book, a pair 'of flexible cover members having their adjacent margins arrangedin overlapping relation, and a back piece having its margins respectively secured to said cover members beyond said overlapping margins and having end flaps for the purpose set forth.

- In testimony whereof I have hereuntosubscribed my name.

GEORGE WASHINGTON NEXYMAN.
