WEATHER STRIPING Filed oct. 3, 1940 Patented vJune 15, 1943 Louis F. Julien, Detroit, Mich., assignor to Chamberlin Metal Weather Strip Company, Detroit, Mich., a corporation of Michigan Application October 3, 1940, Serial No. 359,465

2 Claims.

This invention relates to improvements In weather stripping and refers particularly to weather stripping for sliding Window sashes.

It is an object of the invention to provide weather stripping including cooperating members one for attachment to a conventional sash, and the other for attachment to an ordinary vertical bead provided upon a frame to guide one side of the sash during its movement, and wherein resilient means are provided on the members for retaining them in position so that the use of nails or other fastening means may be dispensed with, or, if desired, a few nails may be employed for positively preventing movement of either member in a longitudinal direction relative to the sash or bead on which it is mounted.

Another object of the invention is to provide a resilient flange along one side of each sash member having its outer longitudinal margin flexed through more than 90 so that the iiange and the outer edge of its flexed margin resiliently engage opposite sides of a longitudinal slot formed in one vertical edge face of the sash; and a longitudinal, laterally flexed tongue formed intermediately of the width of the bead member to resiliently engage opposite sides of a longitudinal groove formed in one side of the bead.

Other objects of the invention are to provide weather stripping: which is cheap to manufacture and easy to install, and which automatically retains itself in position; and which forms a very effective seal to prevent leakage and renders the window fully weatherproof due to the fact that any slight leakage that might occur'between the face of either weather strip member and the sash or bead against which it lies, even when nailed thereon, is effectually stopped by the resilient portion of that member which frictionally engages opposite sides of the sash or bead slot.

Having thus briefly and broadly stated some of the objects and advantages of the invention, I will now proceed to describe a preferred embodiment thereof with the aid of the accompanying drawing, in which:

Figure 1 illustrates a horizontal section showing one side of a window frame and upper and lower sashes therein equipped with sash members, and a bead member mounted upon the parting bead with which the sash members are in sliding engagement.

AFigure 2 is a perspective view of one of the sash members, and

Figure 3 is a perspective view of the bead member.

Referring to the drawing, I designates one side of a window frame having a parting bead 2 and outer beads 3 and 4, thereby forming guides 5 and 6 to receive the vertical margins of upper and lower sliding sashes 1 and 8 respectively. The vertical edge faces of the sashes I and 8 are longitudinally slotted at 9 and l) respectively intermediately of their width, and formed in one lateral face of the parting bead 2 is a longitudinal slot II the outer side of which is substantially in alignment with the bases of the guides 5 and 6 and contiguous to one of them, in the present instance to the guide 5.

I2 denotes sash members, and since they are identical I will now describe one of them. The member I2 has an inwardly directed ange I3 formed along one longitudinal extremity the outer margin I4 of which is exed through more than degrees. The flange I3 bears against one side of the sash slot 9, or I0, preferably against the side remote from the bead 2, and the longitudinal outer edge of its flexed margin I4 engages the other side of the saidV slot and prevents detachment of the ange therefrom. It is of course understood that the sash member I2 is made of material sufficiently resilient to be flexed to permit ready insertion of the flange I3 and its flexed margin I4 into the slot 9 or I 0, and subsequently to engage the slot sides and prevent withdrawal.

Extending from the ange I3, and intermediately of. the width of the member I2, is a bearing portion I 5 to seat against that portion of the edge face of the sash 1 or 8 between its slot 9 or I0 and the parting bead 2. Projecting from the opposite end of the bearing portion I5 is the other longitudinal extremity of the member which consists of an inwardly flexed portion I6 which is again outwardly folded at I'I so that the two portions I6 and I1 which are spaced from one another together form a U-shaped longitudinal guideway I8 open along its outer side. This guideway is disposed between the parting bead 2 and the adjacent face of the sash 'I or 8. In this connection it may here be pointed out that the width of the parting bead 2, or at least that portion of it which projects between the sashes 'I and 8, is less than the spacing between the adjacent faces of the said sashes. t

20 denotes a bead member which, intermediately of its width, is substantially channelshaped as shown at 2| and ts over the inwardly disposed face of the parting bead 2 and the two opposed faces of the latter which extend inwardly from the frame I. The extremities of the channel-shaped portion 2I are folded to terminate in inwardly disposed flanges 22 so that parallel longitudinal grooves 23, which open inward, are provided upon opposite sides of the bead member 2U. Formed adjacent the junction of one side of the channel-shaped portion 2l with one of the anges 22 is a transversely inwardly directed tongue 24 which extends throughout the length of the bead member and is in frictional engagement with opposite sides of the parting bead slot II to hold the said member in position. 2l and 28 denote nails which may be utilized to hold the sash member I2 to its sash 'I or 8 and the bead member 20 to its bead 2 respectively.

From the foregoing it will be readily seen that the guideways I8 of the sash members I2 each receive one of the inwardly directed flanges 22 of the bead member 20; that the inwardly directed portions I 6 of the sash members rest against their respective sashes 1 and 8; and that the outwardly folded portions I'l of the said members each lie between one of the flanges 22 of the bead member 20 and the adjacent side of the channel-shaped intermediate portion 2| of the latter. Thus when either sash 'I or 8 is moved vertically the folded extremity Il of the sash member I2 thereon travels between one side of the intermediate portion 2| and one flange 22, so that the opposed guideways I8 and grooves 23 with their corelated parts form a weatherproof seal which is rendered even more effective because the opposite sides of the sash and bead slots 9 or I0 and II are engaged by resilient portions of their respective members I2 and 20.

While in the foregoing the preferred construction and arrangement of the invention has been described and shown it is understood that alterations and modifications may be made thereto provided they fall within the scope of the appended claims, and particularly that the bead member 20 may, when desired, be provided with a single flange 22 only to cooperate with a single sash member I2 mounted upon a single movable sash.

What I claim is:

1. In a window including a frame having spaced, parallel, vertical beads and a sash supported between said beads for vertical movement therealong, the combination of a longitudinal slot in one of said beads, a channel-shaped bead member bearing against the exposed faces of the slotted bead and including a resilient longitudinal portion extending into and in frictional engagement with the sides of said slot, and said member having at least one reversely ilexed leg along one longitudinal margin forming a groove of substantial depth between it and the adjacent side of said member, said groove being adapted to receive an outwardly directed marginal flange upon a sash member secured to said sash whereby said member is permitted longitudinal movement relative to said bead member.

2. In a window including a frame having spaced, parallel, vertical beads extending inwardly therefrom and sashes supported between adjacent pairs of said beads for vertical movement, the combination of a longitudinal slot in the central bead, one side of said slot being substantially ush with said frame, a channel-shaped bead member bearing against the exposed faces of said central bead and including an integral resilient tongue extending longitudinally in and frictionally engaging the opposite sides of said slot, and said member having reversely curved legs along its opposite longitudinal margins each forming a groove of substantial depth between it and the adjacent side of said member, each groove being adapted to receive an outwardly directed marginal flange upon a sash member secured to one of said sashes whereby each sash member is permitted longitudinal movement relative to said bead member.
