Patented Augrls, 1939 UNITED STATES QFFIQE 1 Claim.

This invention relates to a device designed for attaching sash cords.

Heretofore when it has been found necessary to attach a new cord to the side of a sliding sash, it has ordinarily been necessary to remove the sash from the frame or casing and this has required the services of a skilled mechanic.

An object of the present invention is to equip a sash with a means by which a cord can be attached to the sides without removing the sash from the frame, the device being simple in construction, easily installed, remaining firmly connected to the sash at all times after installation.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of'certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawing the preferred form of the invention has been shown.

In said drawing Figure 1 is a vertical transverse section through one side portion of a sash showing the present invention combined therewith.

Figure 2 is a side elevation of the structure shown in Figure Figure 3 is a top plan view.

Figure 4 is a section through the attachment taken on the line 44, Figure 2.

Figure 5 is a perspective view of the body portion of the attachment.

Figure 6 is a perspective view of the removable portion of the attachment.

Referring to the figures by characters of reference A designates a portion of a window sash provided in each side with a longitudinal groove or channel B, one of which has been illustrated in Figure 1. The device constituting the present invention is adapted to be seated in this channel and is formed. of two parts shown in detail in Figures 5 and 6. The main part or body portion of the attachment is in the form of a longitudinally channelled member I having inturned side flanges 2 spaced apart to form a longitudinal slot 3 therebetween. These flanges are flat and alined with each other. The upper end of the member I is partly closed by a wall 4 which can be made integral therewith and which is parallel with but spaced from the flanges 2. This wall has a threaded opening 5 therein for the reception of a screw as hereinafter explained.

The other end of the body is formed with an integral pointed extension 6 and formed in the member I near its upper end is an opening for reception of a screw 6' whereby said member can be securely attached to the window frame.

In practice it is intended to make the member I out of one piece of strong sheet metal which can be bent to form the channelled portion, the flanges 2, and the tapered end portion 6 produced by properly shaping and inturning one end of the blank. The top wall 4 of the member can be connected to the channelled portion by welding, brazing, soldering, etc., or might even be made integral therewith.

In connection with the member I there is used a removable strip 1 preferably flat and having an oflset ear 8 at its upper end provided with an opening 9. This strip is so proportioned as to be insertable downwardly between the flanges 2 and the head l and to extend longitudinally back of the flanges. A downwardly extended hook I0 or the like is formed on or connected to the strip I preferably near its lower end and is located where it can extend outwardly through the slot 3 as shown for example in Figure 1.

When it is desired to attach this device to a window sash A, the body portion I is positioned longitudinally within channel B and the pointed end portion 6 is then driven downwardly into the lower end wall of the channel until the upper end portion of the member I is located preferably slightly below the top lever of the sash A. A sash cord is then attached to the hook III in any suitable manner. For example a wire II, bent to the form of a figure 8, can be provided, the cord being extended through both loops of the wire after which the lowermost loop is slipped onto the hook I0. It has been found in practice that a connection of this kind will hold the cord securely to the hook without danger of pulling out of the loop. If a chain should be used instead of the cord, one of the links of the chain could readily be slipped onto the hook I0. Member I is secured to the sash by a screw I2 or the like.

After the cord or chain has been attached to the hook the sash, which has been equipped with the member I before it was placed in the window frame, is lowered and strip I is inserted downwardly back of the flanges. 2 until the ear 8 comes into cont-act with the-wall 4. A screw I2 is then used for attaching this ear to'the end wall, the head of this screw being located preferably at or below the top level of the sash. With the parts thus assembled the cord 0 or the like is properly positioned relative to the sash as shown in Figure 1, it being understood that the outward pull exerted by the cord tends to slightly buckle strip 1 so that it will bind tightly against the flanges 2 or the adjacent portion of the body I, as will be apparent by referring to Figure 4, thus supplementing the screw l2 as a means for holding the parts assembled.

Should it be desired to replace the cord C or to remove it for any cause, it is necessary merely to detach screw l2 whereupon the strip 1 can be slid upwardly out of the member I. Following the replacement of the cord, the strip 1 can again be inserted downwardly into the member I and then fastened by means of screw [2.

Importance is attached to the fact that fastening screw [2 does not enter the wood of the sash and, therefore, the opening which ordinarily would be provided for receiving it, will not become worn. Instead the screw is in engagement with metal and will hold securely after repeated removals and replacements. All parts of the attachment are located at or below the top level of the sash so that they will not come against the top of the window casing when the sash is raised.

What is claimed is:

A sash cord fastener including a longitudinally channelled member having a longitudinal slot, the channel in said member having a wall at one end, means projecting from the other end of the member for insertion into the end wall of a channel in a sash, a strip slidable into and out of position within the channelled member, means extending from one end thereof for lapping the end wall of the channel in said member, means engaging the lapping portions for holding them together detachably, and means on the strip and exposed within the slot for attachment to a sash cord.
