Witmoo M my Patented @et 23, 1923.

NEFF@ STTS CHARLES BONHAI/I, OF SAN FRANCISCO, CALIFORNIA.

SASH-CORD FASTENER.

To all whom it may concer/n.'

Be it known that l, CHARLES BONHAM, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and. useful Improvements in Sash-Cord Fasteners; and I do 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.

This invention relates generally to builders hardware and particularly to sash cord fasteners.

The invention has been designed in order to provide a sash cord fastener which can be made very cheaply and economically, one which may be applied very quickly and easily, and one having an improved means for gripping a sash cord.

The novelty in the invention, resides in the various details of construction, and combination and arrangement of parts,

which are hereinafter fully described and 5 claimed, and shown in the accompanying drawing.

In the accompanying drawing, forming a part of this specification Fig. l is an edge view of a sash equipped with a sash cord fastener constructed in accordance with the principles of the present invention;

Fig. 2 is a vertical sectional view of the sashand sash cord fastener;

Fig. 3 is a transverse sectional view taken substantially on the plane indicated by the line 3 3 of Figs. 1 and 2; and

Fig. 4L is a perspective view of the improved sash cord Jfastener, illustrating a sash cord gripped thereby.

In the illustrated embodiment of the invention, the sash cord fastener is shown as comprising a metal strip or bar 1 having it-s upper end bent at right angles to provide an attaching ear 2. The ear 2 is apertured as at 3. The lower end portion of the strip or bar l is widened to provide wings 4 which are designed to be rolled or curved Vtransversely so as to form a conical shape socket 5. Apertures 6 are pierced through edge.

the wings 4 so as to form comparatively sharp inwardly extending spurs 7 on the inside of the socket 5.

The fastener as it is placed upon the market does not have the socket 5 completely formed, but the free edges of the wings 4 are suiiiciently spaced apart to permit the end of a sash cord C to be inserted inthe socket, and when that has been done, the wings 4 may be hammered or otherwise forced together so as to completely form the socket 5 and cause the sash cord C to be gripped by the spurs 7.

To adapt a sash such as shown in the drawing and represented by the letter S to receive a sash cord fastener constructed as described in the foregoing, it must have a groove N formed in the upper` end portion of its side It is also preferable to have a recess R formed in the sash S as an extension of thegroove N. The point or lower end of the socket 5 should be inserted in the recess R and the remaining portion of the fastener should be placed in the groove N with the back of the strip or bar 1 resting flat against the bottom of the groove N. The ear 2 will then extend over the upper edge of the sash S and a screw 8 may be eX- tended through the aperture 3 in the ear 2 to secure the fastener in place. When in place in the grove N, the sash cord C will also be disposed entirely within the latter.

From the foregoing description taken in connection with -the accompanying drawing, the construction, use and advantages of the invention will be readily understood without further explanation.

It is obvious that various changes in form, proportion, and in the various details of construction may be made without departing from the principle or sacrificing any of the advantages of the invention, and hence it is to be understood that such changes may be made within the meaning and scope of the appended claim which defines the novelty of the invention What is claimed is:

`A sash cord fastener comprising a relatively narrow strip of pliable metal having its upper end apertured and bent laterally to form an attaching ear, said strip being widened et its lower end to provide a pair of wings, Said wings being relatively wide at their tops and gradually decreasing in width 5 toward Vtheir lower ends and being adapted to be rolled toward each other to form a substantially conical socket for reception of one end of the cord, said wings being:r provided with indentations forming spurs on the interior of the socket for embedding` in the fibres of Jthe oord. Y

In testimony whereof I have hereunto affixed my Signature.

CHARLES BONHAM.
