SASH-CORD FASTENER.

Specification of Letters Eatent.

Patented N vies), 1921.

Application filed November 4, 1919. semi No. 335,734.

To all whom it may concern: Be it known that I, Lorrus LOWNDES, a subject of the King of Great Britain, residing at Dublin, Dublin county, Ireland, have invented certain new and useful Improvements in Sash-Cord Fasteners, of which the following is a specification. I

This invention relates to improvements in sash cord fasteners for securing balanceweight cords or chains to up and down window sashes, sliding doors and similar structures' I The means heretofore employed for this purpose has been objectionable because it has been necessary to dismember the window frames and remove their sashes therefrom in order to gain access to the said means.

The object of the invention is to overcome this objection by the provision of 'a novel, simple and efficient fastener by means of which the sash cords or chains nray be quickly attached to or detached from window sashes and the like, for repairsand other purposes, and held in proper working relation thereto without the removal thereof from the frames in which they slide.

With the above and related objects in view, the invention consists in the novel construction and combinations of parts hereinafter described and claimed.

In the accompanying drawings, illustrating my invention, I

- Figure 1 is a front view, partly in section and broken away, of one of theupper corners of a window sash having a balanceweight cord attached thereto by a fastener embodying my invention. 3 s

Fig. 2 is an edge view thereof.

Fig. 3 is ahorizontalsection through the sash and fastener, on line 3-3 of Fig. 1.

Figs. 4 and 5 are front and side views, respectively, of the removable fitting of the fastener.

Figs. 6'and 7 are front and side views, respectively, of the permanent fitting of the fastener.

Referring to the drawings, 2 desigatesa portion of one of the upper corners of a window sash, having a, vertical groove 4 formed i'n the stile 5 thereof in the usual location for the reception ofone end portion of the cord 6, by means of which that side of the sash is suspended, within a window frame, the other end portionof th opening 18.

cord being adapted to be attached to a balance-weight, and the body of the cord being adapted to pass over a pulley journaled in the window frame when the sash is-raised and lowered therein in the usual well known manner. V

My improved fastener comprises two fittings 7 and 8. The fitting 7 is permanently attached to the sash 2 and is adapted to receive and retain the fitting 8; and the fitting 8 isremovable frOm thefitting 'T and the sash 2and is provided with means for having the cord 6 attachedthereto.

The permanent fitting? comprises a plate 9 and two spaced parts or arms 10 extending therefrom. The plate 9 is recessed into the wall of the stile 5 adjacent to the lowerend of the cord groove andthe platei9 is secured tothe stile-5 by screws 11 which penetrate the p1ate'9 and are screwed into the seated in the plate 9, so as to present a smooth, uninterrupted outer edge face for the window sash. The arms 10 extend inwardly from the upper portion ofthe plate 1 of the groove 4:.

' The removable fitting 8 comprises along arm 15 having a head 16 formed on the lower end thereof and provided with parts or projections 17 which extendoutwardly 'from opposite sides thereof. Thelong arm.

15 is made slightly concavo-convex incross section,and the head '16 has .a tapered opening 18 extending vertically therethrough.

The opening 18 is flared downwardly'and stile 5, and which have countersunk heads '9 and into the upper portion ofthe expandoutwardly and itis adaptedto receivethe lower expanded orknotted end 19 of the cord 6 and serve as a means. .for attaching the cord 6 to the fitting 8by preventing the enlarged or knotted end .19 of the cord from being drawn upwardly from within the The end of the cord 6 may be expandedto form the enlarged *end 19 by e w rpingepr i d t the cord, y

fitting extends from between the arms 10 of the permanent fitting up through the groove 4 to a point at or near the top of the sash '2 or upper open end of the groove a, and the projections 17 of the removable fitting extend outwardly beneath and in engagement with the horizontal faces let of the arms 10 of the permanent fitting 7. The upward pull of the cord 6 holds the projections 17 in engagement with the arms 10 causing the cord 6 to support'the sash 2; and the inclined faces 13 of the arms ,10, engaging the pro-' j ections 17 hold the removable fitting 8 back against the inner orba se wall 20 of the groove 4. As the longarm 15 extends upwardly from the back of the head 16, the arm 15'lies flat against the base wall and leaves plenty'of room in the groove 4. for the free working of the cord 67in the usual manner.

In assembling the. parts, the end of the cord 6 is expanded or knotted and passed upwardly through the opening 18 in the re movable fitting 8,'outside of the sash 2, until shown in Figs. 1, 2 and 3 to permit the head 16 and its projections 17 to pass down through the groove h lhe fitting 8 is then lowered into the groove l-jlliltll the head 16 passes down between the arms 10 and the 'top of the projections 17 are in a plane a little distancebelow the horizontal faces 14 of the arms 10 and at or near the lower ends of the inclined faces 1.3 of the arms 10. The

I fitting 8 is now given-a quarter turn to bring the projections 17 beneath the arms 10, and

'the'fitting 8 is then drawn upwardly until the top, of the projections 17 engage the horizontal faces 14L of the arms 10, thereby locking the. fittings? and 8 together and preventing the withdrawal of the lower end I ting 8 and cord 6 from the sash 2; and either operation maybe performed without removing the sash2 from the frame in :which it of the cord 6 from the lower'portion of the groove 1. During thisupward movement of V the fitting 8 to engagethe projections 17 with the arms 10, the inclined faces 18 force the fitting 8 back against the base wall 20 of the groove 4-, and, thereafter, retain the lit ting 81 in such position. A reversal of. the operation-just described will remove the fitslides, becauseth-e fitting. 8 may be manipw 'lsdxidi from a position above the upper open end of the groove 4: by the aid of any suitable tool or tools.

The upper end of the long arm 15 of the removable fitting 8 has 7 a hole 21 formed therein for the reception of a suitable tool or implement employed in adjusting the fitting 8 while it is being applied to or removed from the sash 2. I

The plate 9 of the permanent fitting 7 has a slot 22 formed therein which receives one of the projections 17 when the removable fitting 8 is applied to orrremoved from the permanent fitting 7.

I claim; as my invention: 7 1. In a device of the cha-racter'described,
