SASH BALANCE AND WEATHER STRIP STRUCTURE I Fild. June 29. 1951 2 Sheets-Sheet 2 Patented May 16, 1933 UNITED STATES PATENT OFFICE SEEN MADSEN, OF CLINTON, IOWA, ASSIGNOB- TO CURTIS COMPANIES, INCORZPOBATED 0F CLINTON, IOWA, A. CORPORATION OF IOWA SASH BALANCE AND WEATHER STRIP STRUCTURE Application filed June 29,

The object of my present invention is to provide a novel and inexpensive and efiective spring sash balance and method of connecting the same with a window sash and Window frame.

In this connection, it is my purpose to provide a means for connecting the spring balance with the sash and frame in such a way as to facilitate the convenient and inexpensive and simple assembling and installing of the parts.

Another purpose is to provide a means for assembling a spring balance in connection with a window frame for quickl adjusting the connections for springs of different lengths.

Another purpose is to provide a weatherstrip structure of very simple construction which may be inexpensively installed.

Another purpose is to provide such a Weatherstrip arrangement by which there is afli'orded a double weatherseal and a guide for holding the sash in proper adjustment.-

Another purpose is to provide a weatherstrip construction of peculiar shape and having novel means for holding the weatherstrsip elements in place.

till a further ob ect is to provide the structure, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims,and illustrated in the accompanying drawings, in which: p

Figure 1 is a perspective view partly in section of a part of a frame and sash on the line 3-3 of Figure 1.

Figure 4 is a vertical, sectional view illus- 1981. Serial No. 547,612. a

double hung sash assembled in connection therewith equipped with a slightly modified form of Weatherstrip embodying my invention.

Figure 7 is a vertical, sectional View taken on the line 7-7 of Figure 6; and

Figure :8 is a perspective view of a Weatherstrip unit including the members for v engaging the ends thereof and holding it in place.

In the accompanying drawings, I have used the reference numeral 10 to indicate generally the side jamb of a window frame aving the parting stop 11.

In Figure 6, I have shown a slightly different form of frame having the side jamb 10a and the parting stop 11a, the blind stop 12 and the inner stop 13.

In Figure 1, I have shown an ordinary sash 14. In Figure 6, I have shown the upper and lower sash 15 and 16.

In Figures 1 to 5 inclusive, I have shown one form of weatherstri to 8 a slightly different orm.

Where the form of Weatherstrip shown in Figures 1 to 5 is used, I rovide the stiles and the ends of the rail 0 the sash 14 with a vertical groove 17 (see Figure 3) and a spring groove 17a.

I provide a Weatherstrip unit or section indicated at A and comprised preferabl of a single sheet of somewhat resilient s eet metal folded along a vertical central line to form a rather narrow U-shaped portion 18, the walls of which converge as shown, at 19, whence they-curve substantially away from each other and then are shaped to form two opposite channel-shaped or concave portions 20 with the open slot or mouth 21 of substantial width.

I might for convenience call the parts of the Weatherstrip unit on opposite sides of I I the contracted neck portion 19, part A and top rail of the sash an part A In the'installation, the greater portion of the part A is inserted into the vertical slot 17 while the portion A and perhaps 'some oi the portion A projects into a vertical groove 22 in the si e jamb 10. The groove 22 may or may not be provided with a jmetal linin 23. The resilience of the Weatherstrip unit is such that the leaves or members 20 resiliently engage and press against the walls of the groove 22 or the lining as the case mdy be. 4

The portion A may fit rather snugly into the slot 17 but it is preferably to provide some means for insuring the proper holding of the unit in place against vertical sliding plate 25 has a pin or the like 26 extending dciwnwardly into the portion A. (Figure 3.

I will now refer to the form of the device illustrated in Figures 6 to 8 inclusive.

In these figures, the jamb 10a is shown provided with an upright groove 34 for each sash. The groove 34 may be provided with a metal linin 35. similar to the lining 23 if desired. It sash is provided with a cor- -resIponding aligned upright groove 36.

use a Weatherstrip unit B similar in shape to the unit A, except it is substantially wider so as to afl'ord a housing in whole or in part for the sprin 37. For holding the unit B in place I ave provided slightl difierent means From that already describe At the top there is provided a plate 38 attached to and preferabl countersunk in the top of the sash and aving a portion which overhangs the groove 36 and termimates in a down-turned curved plate-like portion 39. (See Figures 7 and 8.) The portion 39 projects into and fits snugly against the wall of the Weatherstrip unit 18. At the lower end of the Weatherstrip unit, I provide a similar plate 40 having a similar portion 41, which is u -turned and projeets into the lower end 0 the Weatherstrip unit.

The plate 40 has horizontal projecting spaced parts 42 between which is formed the hook 43 to which the lower end of the spring 37 may be fastened as shown for instance in F igurel. The spring is then partially housed within the Weatherstrip unit B.

In Figure 4, I have shown a slightly difneoaeee ferent manner of installing the spring in place. For instance, I have shown at the upper end of the spring a series of holes 44 in the jamb 10a. A screw or the like 45 may be placed selectively in one of the holes for thus arranging the upper end of the spring at the hei ht suitable for the particular sash which is eing hung. At the lower end of the spring instead of the member 40 already described, there may be used the member 46 having the lip-turned pin or the like 47 fastened into the lower end of the sash. The

part 46 has an up-turned member 48 simihaving a number of advantages.

When the parts are all installed, the sash may have lateral play or as it were a sort of floating movement, and yet there will be formed a double weatherseal made by the engagement of the resilient spaced side members of the Weatherstrip unit with the walls of the groove in the jamb or the lining thereof.

I have shown a simple and inexpensive means for holding the Weatherstrip units in their grooves. This means includes a simple anchoring element with a member pro ecting within the channel of the weatherstrip.

There is also disclosed means for both holding the Weatherstrip in place and anchoring the spring.

In either form disclosed, the groove in the sash ma be shaped to fit the Weatherstrip and the hitter so made as to engage the walls of the sash grooves under tension. This would have several advantages. In installation, the Weatherstrip units would remain in place after insertion until the holding means had been also installed. The weatherstrip would have a snug fit in the sash, thus avoiding sliding toward or from the frame.

There is an advanta e in supportin the Weatherstrip on the sas and making 1t the length of the sash and projecting it into the jamb, because the Weatherstrip can then be conveniently inserted into posit-ion or removed for repairs or replacement.

There are several advantages in assembling the spring in the manner herein disclosed by fastening it to the bottom of the sash and to the jamb. With this arrangement, the spring can be inserted or removed without the necessity for removing any of the parts oi the window frame. For instance, a string can be fastened to the upper end of the spring and the spring can be dropped down between the sash and the jamb until its lower end projects below the 80 for means of the string and fastened to the appropriate screw 45.

With this arrangement, access to the upv per end of the spring 1s easy and convenient. The point where the upper end of the spring is anchored on the jamb may be quickly and easily varied to suit the conditions of the installation. Itis obvious that changes may be made in the details of the structure and arrangement of parts of my device as here shown,and it is, of course, my purpose to cover by my claims any modified forms of structure or use of mechanical e uivalents, which 'may be reasonably inclu ed within their scope.
