WEATHER-STRIP.

Specification of Letters Patent.

Patented June 18, 1918.

Application filed January 15, 1917. Serial No. 142,441.

`of Chicago, county of Cook, and State of vaus Illinois, have invented certain new and useful Improvementsin Weather-Strips, of

which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to weather-strip and more especially to that type of weatherstrip. which is characterized by the combined use of sheet metal and a soft material in the construction of the strip. The principal object of the invention is to provide a form Of weather strip which may be inexpensively produced and in which the soft material is firmly held by the sheet metal bodyl lportion in lsuch a manner as to be effectively presented to one of the objective surfaces when the said body portion is aplied to the companion surface. Other ob- ]ects attained by the improved form of weather-strip are to facilitate the application of the strip, to render it more effective in-service and to permit of its use upon the upper sash of a window without interfering with the movement of the lower sash.

In the accompanying drawings Figure 1 is a perspective view showing the improved weather-strip and illustrating one of the ways in which it may be used upon a window,

` Fig. 2 is a detail plan sectional view Illustrating a different method of applying the weather-strip to a window,

Fig. 3 is an end view illustrating one of the steps in the construction of the improved weather-strip, and

Fig. 4 is a perspective view of the improved weather-strip, greatly enlarged.

The invention contemplates the use of a strip 10 of any one of the soft materials such as felt, rubber, folded canvas, cotton tape andthe like, used for the various kinds of service in which weather-strips are em' ployed. In carrying out the invention a considerable part of the width of the strip 10 of; soft material is held between the two parts 11, 12, of a centrally folded sheet metal strip. 13 of peculiar form. An important feature of the construction is the form imparted to the folded metal strip 13 by which the projecting portion 14 of the strip 10 1s extended Obliquely away from and at a sub'- stantial anglo to the objective surface upon which the weather-strip is applied.

Preferably the sheet metal strip 13 is Origmally flat. Such a flat strip is then formed to provide an ogoe bead 15 along one edge, an inturned flange 16 along the other edge and the strip is centrally folded to bring its two parts 11, 12, to about the relative position illustrated in Fig. 3. The strip 10 of soft material, as felt, is now laid into the channel thus produced and the weather-strip is completed by closing the two parts 11, 12, of the metal strip13 upon the felt strip 10, the folded metal strip 13 being indented at intervals, as at 17, (Fig. 4) to assist in holding the felt and to facilitate the driving of nails through the folded metal when the weather-strip is applied to an objective surface.

As shown, the ogee bead 15 is formed with its outwardly curved portion 1S remote from the adjacent edge of the metal strip and of greater width than the inwardly curved por- -tion 19 of the bead. An Oblique outstanding Bange 20 is thus formed along the edge of the metal strip and by reason of the adjacent outwardly curved portion 18 having considerable width the flange 20'is rendered elastically yielding against outward pressure. The said flange 2O thus provides a yielding seat or support for the Oblique projecting portion 141. of the soft strip 10.

In service the folded metal strip 13 is permanently secured fiat against one of two perpendicular objective surfaces, as by nails 21. The side, as distinguished from an edge, of the soft strip 10 then contacts with the companion objective surface and this contact is yielding, or elastic. Usually it is immaterial to which one of two objective surfaces the sheet metal strip 13 is applied. In closing the lower edge of a window, as 22, however, the sheet metal strip 13 is preferably secured upon the face of the lower sash, as 23. The projecting edge 14: of the strip 10 of soft material then makes a yielding Contact with the surface of the sill, as 24.

Fig. 1 also shows the' strip permanently secured upon the front stop 25 of the window frame for closing the side-edge of the lower sash. For closing the side edge of the upper sash, as 26, the strip may be permanently applied to the sash, as in the material has its Alateral yielding engagement with the parting strip 27 and the movement of the flower sash 22 is in nowise interfered with. Fig. 2 shows the strip penna nentl)7 secured upon the lower sash 22, at one side, and yieldingly engaging the front stop 25.

While the strip may be permanently secured to either one of the objective suraces,'in the case of Windows, the mounting of the strip upon the frame parts, as front stop or parting strip has the advantage that the yielding engagement of the strip 10 of soft material, with the sash assists in preventing rattle.

I claim as my invention 1. In a Weather-strip, in combination, a centrally folded `metal strip having an outstanding flange at one edge andan instand-- ingv flange at the other edge, and a strip off soft material held between the folds of the metal strip and -projecting obliquely outv Ward therefrom between the said, outstanding and instanding flanges.

2. In a Weathenstrip, in combination, centrallyafolded metal strip havingan out standing flange at one edge, an outwardly curved portion immediately adjacent the said outstanding flange and an instanding' flange at the other edge, and a strip of soft material held between the folds of the metaf strip and projecting obliquely out-Ward therefrom between the said outstanding and. instanding flanges.
