(01. 129-1) My invention relates to portfolios, binders and I prefer to practice my invention, and to accomsimilar structures that are of booklike form and plish the objects thereof, in substantially the which are especially designed for the purpose of manner hereafter fully explained and as more binding together a stack of loose leaves or sheets. particularly set forth in. the claims, Reference 5 More particularly my improvements relate to the is made to the accompa y drawing that forms 5 construction and assembly of the back section a part of this specification. and the manner of mounting the binding strips In the drawing:- whereby I have been able to provide a finished F gure 1 is a view looking at the lower ed of article that presents a neat appearance in either a Portfolio 0 binder Which embodies y e opened or closed positions. In carrying out my tion, the right and left hand portions of the 10 invention I have provided the usual covers and v r d l ave being broken w y nd th back, but in addition to these parts there is Structure S w n Open positionadded what may be called a supplementary or Figure 2 is a fra V ew, drawn in perfalse back that is connected in a novel manner p e, Showing the t u e illustrated in to the covers and back, and there are spaced a d the leaves removed. 15 flanges that form the elongated binding members gu e 3 is a sectional view taken on line 3-3 or strips between which the loose leaves or sheets of 2 nd d wn t a larger c le With the may be removably secured by any suitable means. b d ng flaps in Slightly distorted positions for Thus, when the covers are opened the bound edges the p po e of clearness.

Other objects and advantages will be 'apcover B between the binder-board 5 and facing parent to persons skilled in the art after my insheet 6 as shown in Fig. 3.

vention is understood from the within disclosure. The other binder strip D is spaced above the 55 binder strip just described and is in the form of a lateral flange projecting from the adjacent upper portion of the supplementary or false back In order to face this false back I employ a small piece of facing material and adhere it to the inner surface of the back member C to provide a decorative facing 8a thereon and I extend an edge portion 1a upon the inner surface of the cover A and adhere it to the surface of the binder-board beneath the adjacent edge of the facing material 6 as shown at the left in Fig. 3. The remaining portion of the piece of facing material extends from the back 0 to the upper binder strip D where it provides a facing l2 for the piece of thin binder-board ma forming a part of the upper binder strip. This decorative material also extends across a portion of the under surface of the binder-board Illa as shown in detail in Fig. 3.

It will be noted the portion of the decorative material between the binder strips D and E is close to or at the hinged edge of the lower binder strip E, and in order to secure the parts together, as well as to reinforce the false back I, a piece of strong fabric I3 is adhered to the inside face of the decorative material and has its marginal portions l3a and l3b adhered to the facing portions of the respective upper and lower binding strips D, E. This strong fabric strip or web 53 thus provides the body portion of the supplementary or false back section I that is covered on its outer surface with the decorative facing material and assists in connecting the binder strips D and E together in their spaced relation.

The margins of the back C are reduced in thickness as at I4 to provide flexibility for hinging action between the covers and the back. The false back I also has hinging action with respect to the back C and the adjacent cover B. The binder strips D, E likewise have hinging action at the points l5 and I6, Fig. 3.

From the foregoing it will be book or portfolio presents the appearance as an ordinary book or portfolio, but when the cover A is opened, as shown in the drawing, the leaves remain flat, and the back C will lie flat upon a table, desk or other support while the stack seen the closed The decorative material beside providing the inner facing of the back member C, and an outer facing for the false back I, enhances the appearance of the structure when the cover A has been opened. The reinforcing fabric IS on the false back I will not readily be visible nor will the portions No or I 3b of this material be visible because leaves held against the binder strips will prevent these portions being seen.

What I claim is:

1. A device of the kind described comprising a back section, covers flexibly connected to the longitudinal edges of said back section, a supplementary back section flexibly connected to the before-mentioned structure at substantially the juncture of one of the covers and the first-named back section, binder strips extending laterally from opposite edges of said supplementary back section, and a strip of material extending continuously upon and secured to surfaces of both of said back sections and constituting portions thereof, said strip of material also extended upon the binder strip projecting from the free edge of the supplementary back section.

2. A binder comprising a back section, covers flexibly connected thereto, a supplementary back section extending from said first-named back section and disposed between said covers, a binder strip extending laterally from the free edge of said supplementary back section, a second binder strip co-acting with said first-named binder strip and mounted adjacent the anchored edge of said supplementary back section, and a strip of material secured to and extending continuously across the adjacent surfaces of the said back sections and constituting portions thereof.

3. A binder consisting of inner and outer bodies, each body comprising two spaced members and an intermediate member that are hingedly connected along adjacent longitudinal edges, means connecting a hinge edge of the inner body to an adjacent hinge edge of the outer body, and a sheet of material disposed upon the inside face of the intermediate member of the outer body, the outside face of the intermediate member of the inner body, and also across and concealing the line of connection between said bodies, whereby to adapt one body for hinging movement with respect to the other body, said material providing a finish on the intermediate member of the inner body that is exposed when the outer body is opened.

4. A binder comprising a back section, covers flexibly connected to adjacent edges thereof, binder members one of which is disposed with a margin adjacent the juncture between a cover and said back section, and means connecting said binder members consisting of a body Web secured to opposing faces of said binder members for maintaining them in spaced relation, and facing material secured upon the inner face of said back section and extending across said body web and secured to a face of one of said spaced binder members, whereby another back section is provided independent of the firstmentioned back section, said other back section connecting said binder members.
