WINDOW SEAL STRUCTURE Filed July 19, 1950 JNVENTOR.

. flax/w 5. DAV/.5.

Patented Apr. 22, 1952 UITED STATES This invention relates to a window seal structure and more particularly a weather strip seal adapted for windows of a type which include relatively slidable sashes.

The principal object of the invention is to provide such a seal structure or weather stripping as may be readily applied to the upright side members of the window casing which serves as a parting strip for guiding the sliding movement of the upper and lower window sashes and maintaining them in proper alignment while serving as a seal therebetween. For this purpose the upright side members of the casing are recessed to receive and nest therein a tubular metal parting strip having an inwardly exposed throat for slidably receiving therein the sealing elements secured to the respective sashes. Thus the parting strip serves as an inner guide between the two sashes to retain them in alignment and an effective seal therewith in a manner to permit relative sliding movement while preventing the passage of air, dust, and water thereabout.

Other features of the parting strip seal reside in the ease of installation and removal, and whereby it may be secured without the requirement of screws, nails or the like; and which will eliminate friction in the sliding action of the sashes which ordinarily occurs due to swelling of the wooden members.

The. full nature of the invention will be understood from the accompanying drawings and the following description and claims:

In the drawings,

Fig. l is a horizontal sectional view of a por-,

tion of the left side of a window structure 11- lustrative of the invention.

Fig. 2 is a partial vertical section through the top of the upper sash.

Fig. 3 is the same as Fig. 2 illustrative of the lower part of the lower sash.

Fig. 4 is a partial perspective view showing the junction of the weather strip members with the lower sash partially raised.

Fig. 5 is a diagrammatic illustration of the mode of applying and removably securing the sash parting weather strip in place by a special tool.

In the drawings there is shown a window structure including a mounting frame therefor, which frame embodies upright side members I0 embraced within the window casing indicated at v sash Hi and the lower sash it are adapted to slide relative thereto and to each other in the usual manner, each being provided with the window panes it and i! respectively.

The parting strip i3 is of tubular'channel-like form extending the full hei ht of the window frame between the respective sashes I i and I5 and on each side thereof. As shown herein said parting strip is formed of sheet metal, being preferably rectangular in cross section with a base portion [8 seating in the recess I2 cf the frame member it, with the side walls !9 and projecting inwardly .oi the window frame to provide bearing surface against which the sashes l4 and I5 engage in their sliding movement. Said parting strip may be readily inserted in the recess without the use of screws, nails, or the like by inserting an indenting tool iila of suitable form and curvature to provide an indenting end lfib which, by hammer tapping, will force beads of metal into the Wood as indicated at 580, all as illustrated in Fig. 5.

As above described the side walls i9 and 20 terminate in end sections which extend inwardly and provide side thrust bearings for the" window sashes, as indicated at 2|, 2:2, said end sections in turn are bent inwardly to provide a throat 23 extending longitudinally of the strip throughout the full length thereof and. embraced. by the inturned lips 2d and 25. The metal strip is formed with inherent spring tension wherein its throat is biased to closed position with the

lips

24, 25 normally bearing against each other.

Secured vertically of the sashes and along their respective adjacent surfaces there are provided opposed. Z-shaped metal strips 26 with their mounting faces secured to the inner surfaces of the respective sashes I land their inturned intermediate sections indicated at 2'! approaching each other and bent laterally for termination in the sealing flanges indicated at 28, said flanges each identified specifically by the numeral 29 for sliding contact relative to each other and to the

lips

24, 25 as the sashes are raised or lowered.

Thus the inherent spring tension of the

lips

24, 25 of the throat 23 at all times yieldingly bear against the sealing flanges 28 maintaining a slidable sealing contact with said flanges and in turn maintaining said flanges in sliding sealing con tact relative to each other.

Secured along the upper portion of the top sash I l, and onthe inner side thereof as illustrated in Fig. 2 there is provided a weather strip 32 through the medium of the fasteners or nails 33. A corresponding complementary weather strip 34 is secured to the upper horizontal parting strip 35 by means of fasteners or nails 35. In a similar manner a weather strip 37 is secured along the outer surface of the bottom of the lower sill by the fasteners or nails 38 as shown in Fig. 3. This strip cooperates with the weather strip 39 secured to the sill M] by the fasteners or nails 4!. Thus a weather strip seal is provided at the top and bottom of the sashes in the usual manner and as particularly shown in Figs. 2 and 4.

Through the medium of the sash parting weather strip above described and identified by the numerals i3-29 I obviate the use of the ordinary parting and moulding strips and in old windows make use of the recess l2 from which the usual wooden parting strip is removed. By means of this structure not only is the recess filled and protected but a permanent and effective seal is provided which maintains both sashes in alignment under spring tension eliminating the usual friction which ordinarily occurs due to swelling of parts. Furthermore the installation of this structure requires no coring of the sash, or special tools and through the use of such a tool Mia as indicated in 5 it may be readily installed and as readily removed for replacement or repair.

The invention claimed is:

l. A metal parting strip and weather seal adapted to be secured to a window frame having an inset groove extending intermediate relatively movable sashes, comprising a metal channel-like tube having an inner base portion adapted to be embedded and secured within the said window frame groove to extend outwardly therefrom, said tube being formed an outer exposed throat portion providing a sealing channel extending centrally and longitudinally thereof, and opposed sealing strips of Z-shaped cross-sectional form, each having an inwardly flanged portion thereof secured to the inner sin-"ace of its respective sash in a direction extending from said tube whereby said tube will have direct contact with the respective sashes to serve as a parting strip therefor, each said sealing strip having a sealing flange extending inwardly from the respective sashes and in a direction opposite to said first mentioned flange into and through the throat portion of said tube for sealing and sliding contact therewith.

2. A metal parting strip and weather seal adapted to be secured to awindow frame having an inset groove extending intermediate relatively movable sashes, comprising a metal channel-like tube having its base portion embedded and se= cured within the said groove of the frame to extend outwardly therefrom to provide a parting strip for said sashes, said tube having its outer exposed side formed with a throat portion comprising inturned lips spring biased toward each other, and opposed sealing strips of Z-shaped cross-section carried by the inner surface of each sash respectively inwardly of and free of contact with said tube, each of said strips having'an intermediate section thereof lying adjacent the outer exposed side surface or" said tube to effect a sliding and guiding side thrust bearing for said sashes and terminating in an inwardly turned sea-ling flange extending into said throat for sliding engagement relative to each other and the inturned throat forming lips of said tube to maintain sliding and sealing contact with each other under the inherent spring tension of said lips.

3. A metal parting strip and weather seal secured to and adapted to be secured to a Window frame having an inset groove extending intermediate relative movable sashes, comprising a metal channel like tube having a base portion extending within said groove to provide a parting strip for direct sliding contact with said sashes, said tube being substantially rectangular in cross-section and formed along its outer exposed wall with a threat defined by inwardly extending lip portions spring biased toward each other for normally closing said throat, and opposed sealing strips secured to the inner sur faces of said sashes respectively inwardly of and free from engagement with said tube, each of said sealing strips having a flange portion extending into said throat between said lips for effecting a seal therewith under the inherent spring tension of said lips for permitting relative sliding movement therebetween.

4. A metal parting strip and weather seal as set forth in claim 3 wherein the base portion of said tube is punched into the wall of said groove for anchoring it therein against displacement.
