SASH-CORD FASTENER,

SPECIFICATION forming part of Letters Patent No. 397,680, dated February 12, 1889.

Application filed December 31, 1888. Serial No. 294,985. No model.)

To all whom it Hwy-concern:

Be it known that. I, EDWIN \V. ABBE, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, haye invented certain new and useful Improvements in Sash-(lord Fasteners, of which the following is a specification.

Hy invention relates to improvements in sash-cord fasteners of the class which are designed to be fastened to a cord without tying a knot therein and the objects of my invention are simplicity in construction and convenience and eliiciency in use.

In the accompanying drawings, Figure l is a plan view of my sash-cord fastener with a cord attached thereto. Fig. 2 is a front elevation of the same. tion on line a: of Fig. Ltogether with a portion of a sash; and Fig. at is a like sectional view of my sash-cord fastener alone.

The general form of my fastener may be described as consisting of two circular plates, 5 5, connected by a semi-cylindrical shell or frame, It, the same being adapted for use by being slipped into a round hole in the sash A at the termination of the eord-receiving groove .8 in the edge of the sash.

A sash-cord fastener of this general form, in which the cord C is secured therein bya knot or clasp on the end of the cord with said knot or clasp restin upon the inside of the shell, is old, and hereby disclaimed.

l. dispense with a knot or speeially-formed clasp on the end of the cord. Between the two end plates, 5 5, .l form a cross-bar, 7, and integral with each of the end plates, 5, to-

ward their lower edge, I form a tongue, 5. The top of the shell immediately opposite said tongues is left open for the passage of the cord (.1. The cord is then passed through one of these openings, doubled over the lower edge of the cross-bar, passed up throughthe opening in the shell on the other end of the fastener, when the tongues 8 S are bent or pressed inward by striking them with a hammer or otherwise imparting a like pressure, so as to Fig. is a vertical secbind the metal firmly upon the cord upon both sides of the cross-bar 7 The cord may then be cutoff on one side substantially even with the outside of the shell, and the device is ready to be applied to the sash A, as illustrated in Fi g. I. I prefer to thicken the tongues 9 somewhat at their upper ends, so that in their normal position they will project slightly beyond the outer faces of the end plates, 5 5, while their inside is even with the inner face of said plate, as shown in Fig. 4,

whereby their outer face, after the cord has been secured thereto bybending the tongues, will be even with the outer faces of the end plates, as shown in Fig.

\Vhile I prefer to form a tongue, 8, at each end .of the fastener for convenience of putting the cord in place and for gripping the cord firmly at two different points upon the re spective sides of the cross-bar 7, an efficient; fastener may be formed by the en'iployment of only one such tongue for fastening that end of the cord which terminates at the faston er.

*hen fastened by either one or two ton guess, the fastening is very secure and eflicient on account of the cord being doubled over the cross-bar, so that it has an indirect pull on the fastener; and, furthermore, the fastener is particularly adapted :for use with hard cords, which are very inconvenient, if not impracticable, to firmly secure by tying a knot.

I claim as my invention-- The herein-described sash-cord fastener, consisting of the end plates connected by a shell. or f rame, the cross-bar between said end plates for doubling ihe cord over, and a fastening-tongue formed integral with one or both of said end pl ates for impin n g upon the cord, substantially as deseril'ied, and for the purpose specified.
