REMOVABLE SASH-CO'RD FASTENER.

Application filed March 16, 1923. Serial No. 625,631.

To all whom it may concern:

Be it known that we, FREDERICK DOWLING and ERNEST C. BANNIsTER, each a citizen of the United States, residing at Glen Cove, in the county of Nassau and State of New York, have invented certain new and useful Improvements in Removable Sash-Cord Fasteners, of which the following is a speci- 1 the opposite wall, when at an angle appreaching the horizontal.

fication.

This invention relates to a means for attaching the cords which connect the sashes of windows and their balancing weights, to the said sashes, the invention having for an object to provide an improved fastening means which permits of the cord being replaced in the event of breakage without removing the sash from the window frame.

For further comprehension of the invention, and of the objects and advantages.

ings, and to the appended claims in which.

the various novel features of the invention are more particularly set forth.

Fig. l of the drawings is an edge view of the upper portion of a window sash, showing my improved cord securing device in position thereon.

Fig. 2 is a vertical section on the line 22 of Fig. 1.

Fig. 3 is a detail perspective view of the main bracket of the device.

Fig. 4 is a horizontal section on the line H of Fig. 1.

In the drawing we have indicated at 10 a portion of a window sash of ordinary construction. In the opposite edges of this sash at the top thereof, are formed the channeled recesses such as 11 in which the cord securing devices are located. Since both of these devices are the same only one need be described. This device comprises a troughlike bracket 12 made of sheet metal and which fits snugly in the recess 11, extending vertically up the side of the sash, this membercomprising the main body 12 and the side wings 12*. At the top the main body 12 is extended beyond the side elements 12 and is bent horizontally to lie upon the top of the sash as at 14, this top portion being formed with a number of holes 15 to receive fastening screws 16 which pass therethrough into the sash. The body member 12 is also slotted upwardly from the bottom as at 17 to engage over the shank of a screw 18 threaded into the side of the sash; the head 18 of the screw overlying the sides of the slot and so retaining the lower end of the bracket from outward displacement.

. Struck out from the side wings series of tongues 20 which are arranged in staggered relation on the opposite walls and which are of sufficient length to bite into the sash cord 21 inserted therebetween and The outer ends of thesetongues are preferably cut obliquely as shown. I I

.When inserting the sash cord 21 in the bracket the tongues 20 are bent to an inclination somewhat greaterthan that shown in Flg. 1, permitting the cords to be inserted ,easily in the bracket, being forced upward to the position shown as the bracket is positioned in thevrecess 11. To this end we provide a flat strip 25 which is placed in contact with therear face of the body element 12 and which is formed with a number of ratchet like projections or teeth 26 which project through vertical slots 27 in the ele- I ment "12 under the respective tongues 20. This flat striphas a laterally bent top portion 29 which lies under the element 14 and the teeth 26 are so arranged thereon with. re

spect to the tongues 20 as to engage the under faces of the latter when the same are bent to the inclined position just referred to, with the two partsl and 29 spaced a slight distance apart, the part 29 having openings therein corresponding to the openings 15, 9()

while the strip 25 has a slot in its lower end corresponding to the slot 17 When a new cord is to be connected to the sash 10, the screws 16 are loosened and the attaching device pulled upwardly to remove it from the recess 11. The old cord is removed and the tongues 20 are bent downward, the new cord being then inserted in the bracket 12. The bracket 12 and strip 25 are then inserted together into the recess uno til the element 29 on the strapengages the top of the sash. The screws 16 are then inserted into place and it will be apparent that as the screws are tightened up the bracket 12 and strap 25 will have a relative longiturecess prevents lateral movement of the lower end of the bracket.

While we have illustrated and. described 12 are a 60 a preferred embodiment of our invention it is to be understood that we do not limit ourof a windowsash, means accessible from the top of the sash for securing the bracket to the latter,'tongu'es projected inwardly from the sides of thebracket and adapted to grip a sash'cord, andmea'ns operable from the top of the sash for swinging said tongues into gripping relation with the cord.

2, A device of the class described comprising a channeled bracket adapted to be inserted downwardly into a recess in the side of a window sash,'means accessible from the top of the sash for securing the bracket to the latter, tonguesprojected inwardly from the sides of the bracket and adapted to grip a sash cord, and means operable from the top of the sashfor swinging said tongues into gripping relation with the cord, said last means comprising a strip extending along the bracket and having projections passing-through slots in the latter and engaging under the tongues thereon. 1

3. A device of the class described comprising a channeled bracket adapted to be inserted downwardly into a recess in the side of a wlndow sash, means accesslble from the top of the sash for securing the bracket to the latter, tongues projected inwardly from the sides of the bracket and adapted to grip a sash cord, and means operable from the top of the sash for swinging said tongues into gripping relation with the cord, said last means comprising a strip extending along the bracket and having projections passing through slots in the latter and engaging under the tongues thereon, said bracket and strip having laterally offset ends adapted to be drawn together, and thereby move the tongues into gripping relation to the sash cord, by fastening screws passed therethrough to secure the device to the window sash.

4:. A device of the class described comprising a bracket adapted to be inserted downwardly into a recess in the side of a window sash, means accessible from the top of the sash for securing the bracket to the latter, said means including a horizontal offset on the upper end of the bracket adapted to project over the top of the sash, sash icord gripping members on said bracket, and

fixed elements on the window sash adapted to engage said gripping members and automatically move them toward the sash cord during the final downward movement of said bracket which brings said offset into engagement with the top of the sash. In testimony whereof we have afiixed our signatures. FREDERICK DOWLING. ERNEST C. BANNISTER;
