SPECIFICATION forming part of Letters Patent No. 434,625, dated August 19, 1890.

Application filed May 1, 1890. Serial N0. 350,228, (No model.)

To all whom it may concern.-

Be it known that I, MALCOLM M. CoPPUoK, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in File- Binders; and I do hereby declare the following to be a suificiently full, clear, and exact description thereof as to enable others skilled in the art to make and use the said invention.

This invention relates to temporary binders or clamps for holding documents and loose papers for convenient reference, and has for its object the better facility of introducing and removing papers therefrom and the more secure holding thereof, the diminished liability to injure furniture by projections of fastening mechanisms, and also reduced cost in the production thereof.

To meet these requirements this invention consists in a pair of covers or front and back boards having at the back margin of one or both of each a thickened strip hinged thereto, and in such stifiened strip in one back or cover staples inserted, to which cords are secured, and in the opposite one a clamping mechanism inserted in the recess or panel, so as to clamp the cord after passing through the documents and through the thickened strip of the front cover.

The construction and operation of the invention is shown in the drawings annexed, and hereinafter fully described.

Referring to the drawings, Figure 1 shows a perspective View of a file-cover or temporary binder with papers secured therein; Fig. 2, a section in a vertical plane indicated by the dotted line 00 0c in Fig. 1; Fig. 3, a transverse section in the vertical plane indicated by the dotted line y y in Fig.1. Fig. 4 shows the clamping device drawn on an enlarged scale.

Between the two thicknesses of the back strip 13 are inserted, before cementing them or gluing them together, bent Wires C C, forming staples C, which protrude inwardly and afford points of attachments for cords D. The cords D extend inwardly through holes formed in the strip A passing through a small aperture E in the inner layer of pasteboard in said strip. In the outer layer of the strip A surrounding each of the apertures E, through which the cords D pass, is a rectangular sunken space or panel K, into which the leather covering of the back is molded, and in which is inserted a metallic plate G, having guides or recurved edges G upon its longer sides, in which a slide H is fitted to slide lengthwise.

A perforation G in the plate G, coinciding in position with the hole'E in the strip A serves to pass the cord through. The sliding plate A is made of elastic metal and slightly bowed in the center at one end and nearly fiat, and made quite rigid at the other end by being curved over upon itself at H to afford a hold for the finger-nail to slide the plate by passing the cords through the papers J, placed in the file, and then through the apertures G and, forcing the slide H over the cord, it is securely retained in position. It may be further secured by passing it again through another aperture G: inwardly to the inside of the binder. The plate Gis secured in the recess or panel K by rivets K, the ridges G and curved portion H of the plate H being sunk in the panel to avoid any protuberance beyond the surfaces of the strip A and are thus protected from injury or from scratching and injuring furniture or other objects with which they may come in contact. The ridges G on the plate G serve to stiffen the same, and the plate G, bybeing a stronger and stiffer material than the strip A more than compensates for the impaired stiffness thereof by reason of the portion cut away in producing the panel. K, and being secured by the rivets K firmly to the strip A contributes largely to strengthen this portion of the binder. The ridges G upon the edge of said plate perform the function of guides for the plate H, and also constitute a very efficient bracing to the plate G.

Having described my invention, what I els therein with the stiifening-plates G pro- 10 claim is vided with ridges G, constructed and ar- 1. In a file-binder, the combination of a ranged to stiflen the same and to hold and perforated slide G, having parallel guides G guide the clamping-plate H, substantially as 5 arranged to stiffen the same and guide the and for the purpose set forth.
