Dec. 23, 1941. F. E. GLASS I WINDOW CONSTRUCTION Filed Jan. 15, 1940' FRANK E.GLA s Patented Dec. 23, 1941 UNITED STATES PATENT; OFFICE I 2,267,021 wmnow CONSTRUCTION Frank E. Glass, Detroit, Mich.

3 Claims.

This invention relates to the construction of double hung windows, and particularly to improved combined sash guiding and weather-stripping means therefor.

An important object of the invention is to provide such a window construction which allows very easy movement of the sash during opening and closing of the window, while at the same time effectively sealing the same against unwanted escape of air around or between the sash sections.

A related object is to provide an improved combined sash guide and weather-stripping assembly of very flexible character, so constructed that even in event of severe warpage of the window or frame construction it does not interfere with free movement of the sash, or with its sealing efficiency.

Still another object is to provide such a combined sash guide and weather-stripping assembly which is more economical to construct and install than presently known structures of corresponding efliciency, economy being effected not only in the lowered cost of the construction itself, but by reason of the fact that less accuracy is required in the dimensions and finishing of the sash, frame and other wood parts, and no special contouring of either the sash or frame is required. The cost of the installation is even further reduced by the fact that with my invention it becomes entirely feasible to use a much lighter frame construction than has heretofore been capable of satisfactory performance. This is achieved by reason of the above indicated flexibility of the guide and weather-stripping means, which adapts itself more readily to any distortion or warping which certain of the wooden parts in the warped condisubstantially on the line 5-5 of Figure 1, fragmentarily showing the sill and lower sash, and

I the method of weather-stripping the same.

Figure 6 is a similar fragmentary sectional perspective view of the top rail and upper sash, taken substantially on the line 6-6 of Figure 1, showing the weather-stripping means used to render these parts air-tight.

Figure 7 is a similar fragmentary sectional perspective view taken substantially on the line 'l'! of Figure 1, showing the weather-stripping means used at the check rail joint between the two sliding sash portions and Figure 8 is a sectional view similar to Figure 3, showing a somewhat modified construction.

Figure 9 is a view similar to Figure 8 showing another modified adaptation of the weatherstripping portion only of the invention.

Referring now to the drawing:

The window frame construction may be of al- .most any known or desired type, and no special configuration or treatment thereof is necessary to. adapt such a window, of almost any ordinary wood construction, to receive the combined sash guide and weather-stripping means of theinven- :tion. The details of the window construction will accordingly not be considered. Such a frame is shown in elevation in Figure 1, and generally desmay occur, without reduction in efliciency or in the ease with which the sash may be moved.

Otherobjects and advantages will be apparent from the following description, wherein reference is made to the accompanying drawing illustrating preferred embodiments of my invention and wherein similar reference numerals designate similar parts throughout the several views.

Figure 4 is a view similar to Figure 3 showing 7 .nailing at suitable intervals.

ignated Hi. In the frame construction shown, no wood parting stop is provided extending vertically -,between the tracks for the upper and lower sash.

In its place a metal parting stop is provided as an integral part of-the sash guide of the invention. If the invention is to be installedin an old window, the wooden parting stop may be removed.

As best shown in horizontal section in Figures 2 and 3, the jamb l2 and inside and outside stops l4, l6, respectively, are arranged in the usual manner, and the sash guide assembly, enerally designated I5, is arranged therebetween and secured to the inside of the face of the jamb, as by The sash guide is preferably formed of sheet zinc, or other metal of such character that wood slides easily thereover. The inner and outer edgesof the guide are angularly turned outwardly, as indicated at I1,

l8, to retain the sash between metal guides and prevent wood to wood contact, while at the same time tending to keep paint from cementing the sash to the frame. These flanges are so disposed :as to maintain the free sliding metal to wood contact even though the sash guide is distorted by considerable warpage of the lamb or other parts of the frame. as will presently be explained in greater detail.

An integral parting stop section extends longitudinally of the central portion of the guide, being formed by longitudinal bending of the meta1, as will readily be apparent. The parting stop portion is of dovetail cross section, somewhat wider at its-inner extremity than at its portion nearest the lamb, as will be apparent from an inspection of Figures 2-and 3.

Fitted over and retained by its own friction grip upon the dovetailed parting stop is a resilient weather-strip assembly 25, formed of bronze or other suitable sheet metal. The relaxed cross section of the weather-stripping element is such that it maintains its grip upon the parting stop, while the weather-strip flanges 26, 21 tend to spring outwardly away from the parting stop and thus frictionally engage the upper and lower sash members 2|, 22. .Along the top and bottom rails and check rails of the window an additional sheet metal weatherstripping member, 30, also formed of resilient bronze or the like, is held by nails or other suitable fastening means in such manner that when the window is closed the metal is flexed in a sash and beads 36, 31 on the sash guide flanges "A, ISA.

A further modification shown in Figure 9, demonstrates an adaptation of weather-stripping means only. corresponding in construction to the weather-stripping means previously described, but applied to a conventional wood window, having a wood parting stop 203, the projecting portion of which is shaped to such dovetailed form as to adapt it to retain the resilient weather-strip member 253. This weather-stripping means may easily be applied to old windows, simply by shaping the parting stop in the indicated manner to receive an'd"-retain the weather-stripping element 253, which is held by its own resiliency in the manner previously described. The other edges of such windows may be protected with flexible weather-stripping elemanner to maintain one of its edges in tight engagement with the sash while at the same time urging its other, secured edge, into tighter engagement with the frame. The relaxed cross sectional contour of such weather-stripping means is shown in Figure 6, while the manner of installation thereof is also indicated in Figures 5. 6 and 7. As there shown, such strips are provided with marginal beads provided by folding their free edges inwardly. The beads engage the wood surfaces to be sealed, and the reduced area of engagement thus provided, by increasing the unit pressure, promotes tight sealing.

The sash is fitted in the frame quite loosely, and all play is taken up, and rattling effectively prevented, by the resilient character of the weather-stripping means. The di ections in which the weather-stripping portions are flexible, and the looseness with which the sash is fltted, also permit considerable movement of the various parts of the sash and frame with respect to each other without causing the sash to stick or bind. A most frequent type of warpage, particularly if a li ht frame construction is used. is diagrammatically illustrated in Figure 4. With many reviously used types of weather-stripping,

and with closely fitted windows, such warpag'e" .36. 31, adapted tobear against the sash. These will be seen to cooperate with the beads on the edges of the central weather-strip portions A, 21A- The latter, due to the resiliency of the central weather-strip section, force the sash outments corresponding to those shown in Figures 5, 6 and 7.

I am aware that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and I therefore desire the present embodiments to be considered in all respects as illustrative and not restrictive; reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.

What I claim is:

1. Combined sash guiding and weather-stripping means for a double-hung window, comprising a sheet metal guide assembly having an integral parting stop portion projecting from one face thereof and extending longitudinally of a mid-portion thereof, integral edge flanges projecting from the same face thereof at the outer edges of said guide assembly and cooperating with said parting stop portion to provide guide channels for sash adapted to be slidably fltted thereinto, said parting stop portion having undercut sides, and weather-stripping means carried by said parting stop portion, comprising a sheet metal channel fitted over said stop and having flexible side webs stressed to bear against said undercut sides of the parting stop to retain the weather-stripping means thereupon, and outturned flexible sealing flanges carried by the free edges of said side webs and stressed to bear laterally outwardly against the side faces of sash members fitted in said guide channels, and to urge the sash laterally into engagement with the edge flanges, said edge flanges and sealing flanges being provided with opposite and inwardly facing beads along their free edges adapted to bear against opposite faces of the interposed sash.

2. Combined sash guiding and weather-strip- 'ping means for a double-hung window, compriswardLv and maintain engagement between the II ing a sheet metal guide assembly having an integral parting stop portion projecting from one face thereof and extending longitudinally of a mid-portion thereof, integral edge flanges projecting from the same face thereof at the outer edges of said guide assembly and cooperating with said parting stop portion to provide guide channels for sash adapted to be slidably fitted thereinto, said parting stop portion having undercut sides, and weather-stripping means carried by said parting stop portion, comprising a sheet metal channel fltted over said stop and having flexible side webs stressed to bear against said undercut sides of the parting stop to retain the weather-stripping means thereupon, and outturned flexible sealing flanges carried by the free edges of said side webs and stressed to bear laterally outwardly against the side faces of sash members fitted in said guide channels, and to urge the sash laterally into engagement with the edge flanges, said edge flanges being disposed at diverging obtuse angles with respect to the general plane of said guide portions.

3. In a double hung window construction incorporating a frame, sash guiding means including a parting stop extending along the same and having undercut side portions, sash slidable in said guiding means upon either side of said parting stop, and weather-stripping means carried by the parting stop and yieldably engageable with the sash, comprising a resilient sheet metal strip fitted over said stop and having retaining portions extending inwardly beside the sameand stressed to bend inwardly against the stop and underhanging said undercut portions, whereby said retaining portions hold the strip in position upon said stop, said strip being folded back upon itself along the lines located at the inner edges of said retaining portions, thereby forming angularly outturned sealing flanges projecting outwardly beside said retaining portions, the lines of fold between said retaining portions and sealing flanges lying in said undercut portions of the parting stop, whereby the sash is unable to contact the lines of fold and disturbance of the spring setting of the metal is thereby prevented, said sealing flanges being. adapted to bear against thelsides of said sash facing said stop to prevent leakage of air between the sash and stop.
