heengaan,

To all miic/1a t may concer/a lie it known that l, lliiimr BRUNEL lnnwis, a citizen of the United States of america, residing at New York city, borough of Brochlyn, in the county of Kings and l'fltate of New illorlr, have invented certain new and useful improvements in Loose-Leaf Bind ers, of Which the following` is a speiiiilication.

My invention relates to loose-leaf binders, and particularly to improved means for securingto the binder cover the bach plate of the binder mechanism.

l'n the `accompanyi drawings- Figure 1 is a perspective of a binder cover showingn my improved attaching means ap-f plied thereto; y

Fig. 2 is a similar view showing the back plate in position; and y Figs. 3 and 1 `are perspective views, re spectively,`of the back plate and anchor strip. v

'llhe loose-leaf binder to which my invention particularly relates is of the type shown in the Trussel Patent No, 77 9,1112, dated January 3, 1905, the elements of which are lighter fabric, supported. by cardboi-ird sti enels, or the lilre, and may be provided with side pockets 6 and inner faces, but is in any event complete as a cover Without the anchor strip 7, to which my invention relates. 1n a binder of the present type, the loose sheets are engaged by a binder mechanism of the type shown in the patent and appli cation above referred to. which mechanism is mounted on a metal back plate S. This back plate is of a Width substanitally corresponding to the baclr` 9` of thebinder, and

`the present invention relates to means for securing; this back" plate to the cover in a satisfactory manner Without injury to, or material weakening of, the `cover 5. this purpose I use a strip of strong fabric, such as a strip of muslin or the like, which is stitched at 10 to theV cover, thetivo lines of stitching being spaced apart substantially For mrnnr cervice.

thewidth of the back plate 8, but leaving` i free the marginal ilaps 11 and 12 on opposite sides of the stitching. After the muslin strip, Which for convenience l will term the anchor strip, has been sevved to the cover, the back plate 8 is placed in position with its side margins substantially in register with the lines of stitches 10. The sideflaps 11 and 12 of the anchor strip are then folded over the opposite edges of the back plate and trimmed to 'a Width such that While they overlie the margins of the back plate,

they leave exposed the lugs 13, 14 and 15 on the central area of the back plate, and by which the binder mechanism (not shown)V is secured to the back plate. A suitable adhesive or cement applied either to the face of i the back plate or to the flaps 11 and 12 serves to secure the flaps to the back plate, against which they are firmly pressed by the base of the binder mechanism when the latter is attached to the back plate` The flaps 11 and 12 are thus held in position, not only by the i adhesive, but by the mechanical engagement of the base of the binder mechanism. The anchor strip 7 `thus supports not only the back plate 8, but also the binder mechanism. rfhe thread for the stitching 1() is of any suitable strength to meet the demands upon the appliance, and `the spacing of the stitches is such that the needle holes do not i pierce the cover so closely as to appreciably weaken the latter. (lbviously the spacing of the stitches may vary with the material of the cover, fabric permittinga closer spacing; of the stitches than leather Without affecting the mechanical strength of the cover.

The underlying thought of the invention is to secure the binder mechanism supporting plate to the cover by means of a fabric strip stitched to the back of the cover, and li do not limit-my invention to the precise form and arrangement of parts shown in the accompanying drawings.

I claim as my invention- 1. In a loose-leaf book, a cover, a back plate for supporting' abinder mechanism arranged Within the back of the book, and a fabric stitched to the cover and underlying,- said back plate, the opposite margins of said fabric being folded back over the back plate to hold the latter in position.

2. In a loose-leaf book, a cover, a back plate for supporting` a looseleaf binder mechanism Within the back of the cover,

and a fabric strip interposed between said strip stitched to the back of the cover and back plate and cover and stitched to the lathaving side flaps overlying the side margins ter, and having marginal flanges overlapof the back plate and secured thereto, but ping the sides of the back plate and Secured leaving exposed Said centrally arranged 5 thereto.
