WINDOW-SASH CO'UNTERBALANCE.
Application filed February 21, 1927. Serial No. 169,689.
My invention relates to improvements in window sash counter-balance.
The object of my invention is to provide a spring counter-balance for window sashes which will not only be substantially constant in its effective support of the sash to be balanced, but which will be easily installed in any standard window frame. Another object of my invention is to provide a sash counter-balance for a plurality of window` sashes mounted in a single frame and comrising a plurality of springs interconnected y a single cord or chain for simultaneous counter-balancing of said sash. It is a furthere object of my invention to provide an easily adjustable spring balance.
In the drawings:
Figure 1 is a front vertical elevation of two sashes mounted in a window frame and showing a portion of the sash and frame cut away to exhibit my device.
Figure l2 is a sectional View of a side elevation of a window frame equipped with my improved counter-balance.
Like parts are identitiedby the same reference characters throughout the several views.
My invention may be incorporated lnto any standard window frame such as the one shown at 1 in the drawings. As is customary in the construction oi such frames, provision is made for guideways for upper and lower sashes 2 and 3 respectively, so that the sasiay be slidably moved upwardly 'or down ardly as desired.
Standard construction of window frames also provides a compartment adjacent the vertical member 4 of the frame and usually' walled in upon the outside of the compartment by studdin of other portions of the frame of the bui ding as shown at 5. It is within this compartment 6 that my device is installed. Pulleys 7 and 8 may be prosash 3, through a diagonal bore 13 and thecord groove 14 over pulley 8 into the compartment 6, where it follows continuously through a series of pulleys 14, 15 and 16 and over the large pulley 7 to the pocket 17 at the end of groove 18 in the `side of the side member of sash 2. This cord or chain 10 is constantly under tension imposed thereon by means of springs 14a, 15a and 16a which are disposed in the compartment 6 as follows. A pair of hooks 20 secured to the sill 21 provide anchorageA for springs 14a and 16a which are held in an erect position by the cord upon which they are adapted to pull. The hook 22 secured at the top of the frame within the compartment 6, provides anchorage for spring 15a which in turn resiliently supports a pulley 15 over which the cord or chain 10 is entrained.
It will be obvious from the above' description that the system of springs and pulleys over which the cord 10 is entrained, will provide an extremely resilient counter-balance for the window sashes 2 and 3, for the sprin s 14, 15- and 16a may be made long and exible in the ample space provided in the compartment 6 to the end that any movement o the sashes 2 and 3 within their guideways may be possible without variation substantially in the amount of counterbalancing action induced by said springs. Installation upon the anchoring hooks 20 and 22 compared with the usual installation of counter-balancing weights will be simple and easy and a provision for an adjustment hereinafter described 'will enable any work man to quickly install my device in any standard window frame.
Provision of a pocket 11 at the bottom of sash 3, and the diagonal bore 13 extending from said pocket to the other groove 14 provided for cord 10, forms a means for quick adjustment at any time of my spring balance. Upon the initial installation of my device in a window frame, the cord will be extended over the pulleys as indicated above and will be extended through the guideway 14 and through the bore 13, so that the extended end of the cord or chain will be subject to easy manipulation through the pocket 11. Little practice will be necessary to enable any workman to judge the amount of tension necessary for a particular window installation. A readjustment may be easlly and quickly made by simply pulling the cord from the pocket 1l and tying the knot or providing any other stop for the `lois cord or chain at greater or lesser lengths for adjustment lof the spring tension.
In installations where there is likelihood that moisture might accumulate in pocket 1l and deteriorate the cord at the point where the knot is secured in said pocket, a small amount of putty inserted in the hole after the adjustment has been made will protect'the cord againstsuch deterioration.
l claim:
1. The combination with Va frame providing guideways, of a plurality of sash reciprocable in said guideways, a single cord interconnected between said sash, and a plurality of counter-balancing springs providing tension upon said cord.
2. The combination with a 'ame provid- .Lezama ing 'uidewaya of a plurality of sash reciproca le in said guicleways, a-single cord interconnected between said sash, and a plurality of springs providing counter-balancing tension upon said cord in all positions of said sash in said guideways.
3. The combination with a frame providing guideways, of a plurality of sash reciprocal in said guideways, a plurality of springs attached at spaced points to the frame, a pulley for each of the springs and a single cord unconnected between the sash and passing alternately over the pulleys, whereby to counter-balance the sash under the control of said springs.
