' WINDow-ooUiv'rnnB'ALAnon Application filed August 11, 1919. Serial No. 316301.

T 0 all w 7mm it may concern Be it known that I, ERIK SON, a citizen of the United EJtates, residing at Baker, in the county of Baker and State of Oregon, have invented new and useful Improvements in VVindow-Counterbalances, of which the following is a speclfication.

This invention relates to window construction and hasfor its primary object to simplify the construction and arrangement of a counter-balanced window sash. v

Another object of the invention is to provide novel means for connecting the upper sash with the lower sash to provide for simultaneous movement thereof, so that when the lower sash is raised, the upper sash will be correspondingly lowered and vice versa.

A further object is the provision of novel means for securing the cord employed for connecting the sashes, to the sash, the said means permitting of a quick and accurate adjustment of the cord so as to compensate for shrinkage and expansion of the same;

Other objects and advantages of the invention will appear as the following description is read in connection with the accompanying drawings.

In the drawings: V

Figure 1 is an elevation of a window with the invention applied thereto.

Fig. 2 is a horizontal sectional view of the same. V

Fig. 8 is a vertical section.

Fig. 1 is an enlarged section through the adjustable connection between the cord and the sash. I

Fig. 5 is a detail perspective of the cord carried member.

Fig. 6 is a similar view of the perforated plate.

Fig. 7 is a view of .a spring wire member for threading cord through the pulleys.

Referring to the-drawings in detail, like characters of reference denote correspond ing parts throughout the several views.

In illustrating the invention, there 'is shown a window casing, which is indicated at 10. Mounted for sliding movement within this casing in the usual manner, is an upper sash 11 and a lower sash 12.

Mounted upon the top of the frame 10,

near each side thereof, is a sheave, which includes a grooved pulley 13 and a bracket or casing 1 1, the latter being secured upon the window frame by screws orsimilar fastening devices 15. Operating over the pulleys 13, is a sash cord 16, thelatter passing through openings .17 in the top of the frame 10. One end of each of the cords-16 is permanently secured to each side of the upper sash 11 nearthe top thereof, as indicated at 18, while the opposite end is adj ustably secured to the adjacent side of the lower sash, also near the top.

This last mentioned securing means is of novel construction and, permits of an adjustment so as to properly regulatethe con nection between the sashes, to allow for shrinking and stretching of. the cord. This adjusting means comprises a stripof metal. 19, which is transversely curved and secured to the lower sash within a socket or notch, as indicated at 20. The end of the strip 19 extends above the top of the sash and is provided with spaced openingsor perfora- Olamped upon the end of the cord 16, is a hook member which comprises a' substantially cylindrical body portion 22 and a projection which is bent to form. a hook 28, the latter being adapted for insertion in any one of the openings 21 to adjustably connect the end of the cord to the sash.- By this means proper adjustment may be eifected at any time, so as to compensate for shrinkage and expansion of the cord.

In Fig. 7 there is illustrated a spring wire member 24, which is provided upon one endwith a hook 25, for threading the cord through the pulleys. The hook 25 is inserted in the end of the cord and the spring wire'member threaded through the pulley, whereupon its end may be grasped and the cord pulled through.

The invention is susceptible of various changes 'in'its form, proportions and minor details of construction 7 and the rlght 1s herein reserved to make such changes as properly fall within the scope offlthe appended claims. r

Having described the invention, what is claimed is: I I

The combination with a window including a casing and upper and lower sashes slidably mounted therein, a sheave mounted cured to the opposite end of said cable, with upon the top of the frame near each side a reduced extension projecting beyond the thereof, and a cable passing over each of lower end of the sleeve, and terminating to 10 said sheaves, and having one end permaprovide a hook to bev interchangeably renently secured to the upper sash, perfoceived by said perforations.
