SASH-CORD FASTENER.

Application filed September 17, 1926; Serial I \To. 136,139.

Thei'inventionrelates to a sash cord fastener, designed for the securlng of balancewelghts, cords or chains to shdmg window sashes, doors or similar structures with disof mutilating the sash, door frame or other structure, and in event of the breakage of the cord or chain, the same can be released from the structure supported thereby, withoutthe necessity of dismembering the window frame and completely removing the sashes therefrom, in order to have access to i the fastener for, the cord or chain.

Another object of the invention is the provision ofa fastener of this character, wherein one part is made permanent to the frame of the door or window; sash of the sliding type and the other part is adaptable for detachable connection with the balance weight cord or chain, which latter part is constructed to detachably interlock'the first named part permanently fastened upon the frame of the door or sash, so that in event that it' is desired to release thecord or chain from such window sash or door, the same can be accomplished with dispatch and without the removal of the window sash from the window frame or the removal of the door from its slide-way, the parts being readily accessible and are capable of quick connection .with each other and removal one from the other, as the occasion may require.

A further object of the invention isthe provision of a fastener of this character, wherein the construction thereof is such to eliminate any special mortising of the sash of the window frame or the sliding door in its sliding-Way and the balancingweight cord or chain can be readily connected with or disconnected from the sash or door, without the necessityof the use of any tools.

A still further object of the invention is t the provision of a fastener of this character,

wherein the balancing-weight cord or chain is connected therewith in a novel manner, so as to eliminate any possibility of the accidental detachment of such cord, when the sash or door is moved up or down" in the frame for thesame t-he fastener being of novel form and can be readily mounted in the sash of a window ora door, or'other like structure supported for sliding movement.

A still further object of-the invention'is theprovision of a fastener of this character,

which is extremely simple in construction,

thoroughly reliable and efiicient in its, purpose, possessing but few parts, strong, durable and" inexpensive stall. a

With these and other objects in view,"the invention consists of the features of conto: manufacture anddnstruction, combination and arrangement of parts, as will be hereinafter more fully described indetail, illustrated in the accompanying drawing forming a part of this specification, which discloses the preferred embodiment of the'invention, and pointed out in the claims hereunto appended.

In the accompanying drawing Figure 1 is a fragmentary elevation of a window sash and window frame of conven tional form, these being-partly broken away to illustrate the sash'fastener constructed in accordance with the invention and in position upon the sash.

Figure 2 is a View similar to Figure 1, showing the sash cord fastener partly in section, to illustrate certain details of the same.

Figure 3 is a fragmentary edge elevation of the window sash, showing the sash cord fastener in elevation, the'sash cord or chain being partly broken away.

Figure 4 isa fragmentary plan view of the cord carryingfastener. I V,

Similar reference characters indicate corresponding parts throughout the several member of the sash cord chain fastener constituting the present invention. It is to be understood that the sash cord fastener is not limited in its use to a window sash, but may be used, in connection with sliding doors or otherlike structures. v 1

The window sash A and the outer'edge of its side, rail confronting the way for the A des- Y .of members, one being designated a male member 6 and the other being designated a female member 7 the latter being of slightly greater length than said male member 6 which .is adapted to accommodate the latter. These-members 6.and 7 are preferably made .frommetal strips, althoughthe same may be made from any other suitable material -and the female member 7 .is adapted to be fastened .in the recess or channel 5 to be coextensive with a major portion of the leg of the same, the lower portion of said mem her 7 being bent on itself to provide a hook .8 .havingan offset 9 and a .resilient bill 10 for a purpose presently described.

Themale member 6 is straightthroughout .its length and .is formed with a restricted portion 11 slightly removed from one end thereof and .an elongated opening or slot 12 contiguous .to the restricted portion 11, which latter is cut into from opposite edges to provide notches 13 for. the anchoring therein of wrapping of strands 14 which secure the terminal 15 of the balance-weight cord 16 to the malemember 6.

It :is .of course understood that the sus pension chain or other like element-can be fastened to the male member 6 in lieu of the --.cord 16. fiThecord 16 isfastened to the male member 6 by training said cord along one .theslot 12in the member 6 so that the terminal 1.5 will be deformed and lie against the opposite facev of the member .6, the re stricted portion 11 and thereafter the wrap- .pingnrstrands 14L twisted about this restricted portion and anchored in the .notches 13 in the edges thereof, so that the terminal .15 will be securely fastened and the cord 16 united to this male member 6 as is clearly apparent in Figures 1 and .2 of the draw Struck .from the male member 6 at a point slightly removed from the upper outer end thereof is a hook-like ear 17, which extends from the side of said male member 6 opposite the location of the cord 16 fastened member 6 which is adapted to be positioned between the .ears 1,8.in1parallel relation to the female member 7 fastened within the recess or channel 5 in the side rail of the sash A as is clearly illustrated in Figures 1, 2 and 3 ofvthe drawing.

In attaching the balance-weight cord to the sash A, it is of course, understood that such cord 16 is fastened to the male member 6 in a manner hereinbefore described and that the female member 7 has been fastened in the recess or channel 5 in the side rail of the sash A. The male member 6 is passed through the upper open end of said recess or channel 5 and inserted in the hook 8, to a point to permit the hook car 17 to pass freely beneath the keeper or cross pin 19 of the female member 7, so that on a slight upward movement of the male member 6 the said hook car 17 will be detachably engaged with the keeper or pin 19 and in this manner the sash cord will be connected with the sash A. The bill 10 will hold the male member 6 in its relative position to the female member 7, so as to prevent said male .member 6 from working outwardly of the recess or channel 5, and thus eliminate any possibility of the accidental detachment of the cord 16 from the .side rail of the sash A.

Should it be desired to detach the cord 16 it is only necessary to force the male'mernber 6 downwardly into the hook 8, the offset 9 being designed to properly guide said male member until the hook ear 17 is freed from the keeper pin 19 and said member 6 is free to be removed from the recess or channel 5 in the side rail of the sash A, this being clearly apparent.

From the foregoing it is thought that the construction and manner of use of the sash cord fastener will be clearly understood and therefore a more extended explanation has been omitted.

l/Vhat is claimed is 1. A sash cord connector comprising a pair of members, one of said members being designed to be set into the side rail of a window sash and having a keeper, the other member being adapted for slidable and removable engagement with the first men tioned member and having a projection for detachable locking engagement with the keeper, said last mentioned member being formed with a restricted portion and a slot, the latter being designed to receive a balance-weight cord, and means for fastening the end of the cord after its passage through the slot to the restricted portion of said member.

2. The combination with a slidahle element having an elongated recess in one side edge thereof and opening through the top of the same, of a sash cord fastener comprising interfitted male and female members, the female member being designed to be fastenedin the recess and coextensive therewith for a greater portion of its length, a keeper arranged on the female member, said male member bein formed with a restricted portion and a s 0t contiguous thereto, the latter being designed to receive the end portion of a balance-weight cord, whereby the terminal thereof will lie along the restricted portion of the male member, means for removably fastening the terminal portion of the cord to the restricted portion of the male member, and means on themale member for detachable engagement with the keeper on the female member, when said male member is interfitted with the female member.

In testimony whereof, I afiix my signature I hereto.
