In order to as claimed increase the reslhency of the Wall2 and also A preferred and practicalembodiment of to pe the ehamlel p j of the Strip to e i ti i shown i th accompanying readlly adapt itself to sllght inequalities in drawings, in which: the metal sash the edge of the wall 2 is pro- Figure 1 is a vertical sectional view of a vided with an inturned lip portion 4 which extends throughout the length of the strip resilient weather-flange connected with the and provides a normall restricted mouth or "inside wall of the channel. g

In testimony whereof I hereunto aflix my opening 5 between the, ee edge of the outer wall 2 and the bent edge. of the inner wall 1 which has the flange B oined therewith.

As will be apparent from Figs. 3 and 4 when the clip portion A'is fitted over the frame part F the outer wall 2 does not contact with the outer face of the frame member throughout the area of its inner surface, but is spaced therefrom to permitthe ripping lip 4 to exert its full influence to raw the inner wall 1 firml into frictional engagement with the insi e edge of the frame part. This construction permits of fitting the strip to the sash by telescoping the clip over the edge of the sash in such a way as to-cause a thoroughly practical and reliable firm engagement between the strip and the sash which dispenses with special fastenings or fittings.

The flange B carried by the inside wall of the clip portion A is adapted to contact with the jamb, sill or other part of the Window frame designated. generally as W, and in case the strip is applied to the top, bottom or free edge of the easement sash the flange B will be yieldingly compressed between the outer face of the window frame and the inner face of the frame part F of the sash. In other words the flange B willbe folded back against the inner wall'l of the clip. However, when the strip is applied to the frame art G located at the hingedside of the winow, the flange B preferably. straddles the corner W of the window frame. Thus, both sides of the flange B can function as closure members for the window opening.

From the foregoing it will be apparent that the novel and distinctive features of the present invention reside in the provision of a continuous self securing or holding metal weather-strip whichymay be readily fitted to metal sash in a practical and expeditious manner, and which otherwise fulfills the objects heretofore set forth.

Without further description it is thought that the features and advantages of the in vention will be readily apparent to those signature.

I claim A metallic weather-strip construction for steel frame easements and the like comprising a clip portion of channel formation and having both walls thereof substantially the same height, and one of the walls thereof being 'deflected inwardly at an angle along its edge to provide a gripping lip for biting engagement with an outside face of the frame, and a
