'JAMES A. BURKE, OF ALBANY, NEW YORK.

TEMPORARY BINDER.

SPECIFICATION forming part Of Letters Patent No. 433,559, dated August 5,1890.

Application filed February 28, 1890. Serial No. 342,052. (No model.)

To aZZ whom it may concern.-

Beitknown that 1, JAMES A. BURKE, a citizen of the United States, residing at Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Temporary Binders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to provide a temporary binder adapted to securely fasten together sheets, pamphlets, and documents of all kinds, and to permit ready reference to the same, and also to permit the bindingcord to be readily lengthened and renewed when desired. These objects I accomplish by the means illustrated in the accompanying drawings, in which- Figure 1 represents a plan view of the front cover of a binder embodying my invention. Fig. 2 represents a plan view of a back cover for the same. Fig. 3 is a vertical cross-section of the front and back covers and a series of leaves secured between the same.

Fig. 4 represents a plan view of the inner side of the front cover. Fig. 5 represents a perspective view of an eye-stud adapted to be secured to the front cover. Fig. 6 represents a vertical cross-section of a tying'button secured to a portion of the back cover.

A represents a front cover having a fastening strip A, flexibly secured thereto by means of the flexible joint d, extendinglengthwise of the cover. The fastening or binding strip A is provided with an eye-stud a, having its base or larger portion on the outside of the front cover, as shown in Fig. 1, and

the eye portion at, extending through the cover, and, if desired, it may extend up through a considerable portion of the leaves. The binding-cords C are tied to the eye a of the stud a, preferably at a point somewhat distant from the end of the cord, so as to leave a portion thereof between the inner side of the front cover and the first page of the bound sheets, the purpose of such a construction being to provide means for lengthening the cord when additional sheets are placed in the binder without having all of the surplus cord exposed to view, on the outside of the cover. When the surplus cord is inforations 0.

closed from view, as in the construction shown, the binder presents a much neater and finished appearance without detracting from its utility. The cord may be lengthened by untying it from the eye a and securing it again at a point nearer its end, and when the cord becomesworn it may be readily taken out and a new one substituted.

B represents the back cover provided on its fastening or binding strip B with the per- Tying-studs b are secured to the fastening-strip at a point near the perforations, and they consist of an outer flaring head arranged in a plane slightly above the plane of the cover and an inner flange 1), arranged inside the cover and provided with a shank extending through the cover and head and riveted at its end to the flaring head I).

The sheets or documents to be bound are secured in place between the covers by means of perforations formed on the edge of the papers corresponding to the perforations c of the binding-strips. The free end of the cord is passed through said perforations in the pa pers and covers and then wound around the tying-button b, and if the cord be long enough it may be brought over to the opposite stud and wound in the same manner, or they may be tied by a knot at a point midway between the buttons, as shown in Fig. 2.

The shank of the eye-stud a, when lengthened, serves as a rigid pin to keep the sheets from shifting from their respective positions while the cord is loosened, as when a sheet is being taken from or added to the series.

In binders of this kind it has heretofore been common to pass the free end of the cord through openings formed in the fasteningcleats, and then drawing the cord over the edge of the cleat wind it around the shank of the cleat under the flaring edge, but in such constructions the first turn of the cord does not obtain a secure hold on the shank and the end of the cord soon becomes loose. In myeonstruction, however, the hole through which the free end of the cord is secured is arranged separately from and independently of the cord around the shank obtains a strong and secure hold which prevents the end from becoming loose.

What I claim is The combination, with the covers A and B, provided with binding-strips flexibly secured thereto, of the eye-studs a, secured to the binding-strip of the front cover, and provided with a shank and an eye a, separate binding-cords C, adjustably secured to said eyes and passed through the perforations 0', formed in the binding-strip of the back cover, and the fastening-buttons b, constructed and arranged on said binding-strip independently of the perforations 0, whereby the free end of the cord, after leaving the perforations, is adapted to be wound around the shank of said button, so as to lie in a plane entirely below the flaring edge of said button, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES A. BURKE.
