SASH -QQRD FASTENER.

SPECIFICATION forming part of Letters Patent No. 755,136, dated March 22, 1904.

v Application filed JEREMY 1904- To all whmn it may concern.-

Be it known that I, GEORGE WAs'HBURN HOWARD, a citizen of the United States, residing at New London, in the county of New London and State of Connecticut, 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 to improvements in sash-cord fasteners. I r

The object of the invention is to provide a sash-cord fastener which may be quickly and easily applied to a Window-sash and readily removed from the same without the useof tools and with which the end of the cord is connected in such a manner as to be quickly and easily removed.

A further object is to provide a fastener of this character which will be simple, strong and durable, inexpensive, and well adapted to the purpose for which it is designed.

With these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claims. 7

In the accompanying drawings, Figure l is a vertical sectional view through a windowsash, showing the application of the invention. Fig. 2 is a detail perspective view of the device removed from the sash. Fig. 3 is a vertical sectional view, and Fig. t is a horizontal sectional view, of the same.

Referring more particularly to the drawings, 1 denotes the window-sash, in each of the side edges of which is formed a recess 2, from which extends an upwardly-projecting passage or channel 3 .for the accommodation of the sash-cord 4, on the end of which is secured the fastening device 5, which is adapted to be seated in the recess 2 and to engage the walls of the same to hold the fastener in place.

The fastening device 5 comprises a tapering or conical-shaped socket-piece 6, one side of which is open or cut away. The edges of Serial No. 188,125. (No model.)

said opening are bent inwardly to form retaining flanges or guides 7, between which is slidably mounted a clamping-plate 8, the edges 9 of which are bent outwardly to engage the guide-flanges 7, and thereby slidingly hold the plate 8 in place. The end of the sash-cord 4 is placed in the socket-piece 6 and the plate 8 slipped in beneath the guide-flanges 7 and into engagement with cord 4. On the inner side of the plate 8 are formed a series of notches or teeth 9, which are adapted to bite into the cord to prevent the same from slipping on the plate 8, so that as the cord is drawn upon by the weight of the sash the plate will be slipped upwardly in the socketpiece, and thereby tightlywedge or clamp the 'cord inthe narrow upper end of the socket,

as will be understood. I

In order to removably secure the cord-holding socket to the sash, a rearwardly and downwardly bent attaching-plate 10 is formed on the inner lower edge of the socket-piece 6, and on the rearwardly-bent portion are formed upwardly-projecting teeth or prongs 12,which are adapted to be forced into the upper wall of the recess 2. On the downwardly-projecting portion of the plate 10 are formed rearwardly-projecting teeth 13, which are adapted to engage the rear wall of the recess 2. The engagement of these teeth or prongs 12 and 13 with the walls of the recess 2 serve to hold the plate and cord-retaining socket in place in the recess 2'and channel 3 in the sash. It will be seen that the heavier the sash or stronger the pull on the sash-cord the more tightly will the cord be clamped in the socket and the more firmly will the teeth or prongs on the attaching-plate be forced into the walls of the recess to hold the plate in 'place.

From the foregoing description, taken'in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minordetails of construction may be resorted to without departing from the prin- Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is

1. A sash-cord fastener, consisting of a tapering socket, having a removable cord-holding plate, means for retaining said plate in place, and means for attaching said socket to the Window-sash, substantially as described.

2. A sash-cord fastener, consisting of a tapering socket, having a removable cord-holding plate, means for retaining said plate in place, an attaching-plate formed on said socket and teeth or prongs formed on said plate to engage said sash and hold said fastener in place, substantially as described.

3. A sash-cord fastener consisting of a tapering socket, having an opening in one side of the same, retaining guide-flanges formed on the edges of said opening, a cord holding or clamping plate adapted to slidably engage said flanges and close said opening and clamp the end of a sash-cord in said socket, cord-engaging teeth formed on said plate, an attaching plate formed on said socket, teeth or prongs formed on said plate to engage the Window-sash and removably hold said socket in place, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.

GEORGE WASHBURN HOWARD.
