2 Claims.

This invention relates to weatherstrips. Objects of the invention are to provide an imsealing contact door.

Another object of the invention is to provide an improved weatherstrip comprising a holding with the Window sash or with a Other objects .and advantages of the invention should be readily apparent from the following description, reference being made to the annexed drawing, in Which- Fig. 1 is a perspective View weatherstrip provided with ;copically engaging a holding member.

Fig. 2 is a perspective View of a portion of the iolding member with which the weatherstrip hown in Fig. l is adapted to he engaged.

Fig. 3 is an enlarged sectional view showing my mproved weatherstrip in connection with a mea-llic window part, the cooperating window beig omitted and the weatherstrip being eX- ended.

Fig. 4 is a similar sectional view showing the eatherstrip compressed by the cooperating indow.

Fig. 5 is a broken sectional View showing a tir of weatherstrips for sealing the horizontal [ges of a pivoted window section.

Fig. 6 is a horizontal sectional View showing y improved weatherstrip attached to a Window of a portion of a means for tele- Louis, Mo., a corframe in rwhich mounted.

Fig. 7 is a view and door frame weatherstrip.

This is a continuation, in par-t, oi' my application Serial No. 295,902, led September 21, 1939, for Window operator.

The holding member l is made metal and is adapted a sliding' window sash is showing a portion of a door equipped with my improved strip by telescopic engagement.

The weatherstrip proper comprises a resilient strip of sheet metal bent to provide a iat portion 1 having a width approximately equal to .the width of the holding member a portion 8 4arm 9 may be provided with an angularly extended margin l l defined from the arm 9 by a curved formation I2 and having its edge I3 doubled under said margin l l for strengthening purposes. Also, the free margin I4 of the portion 3 may be folded against the underside of said portion 8 for additional strength, etc.

manner, the reinforced margin abuts against the ange 6, thereby effectively preventing disengagement of the parts, the pressure of the portion 8 against the arm 5 by the inherent resiliency of these parts further securing the Weatherstrip to the holding member. When the swinging Window section 4 is closed, the arm 9 is bent to a fur-ther extent toward the portion 1, as should be understood by reference to Figs. 4 and 5, thereby providing an effective and substantially hermetic seal.

As shown in Fig. 6, my improved Weatherstrip may be used with equal advantage in connection with a Wood window frame and window sash. When mounted in a Wood Window frame, the holding member I may be welded to a metallic attaching strip I1 and thereby maintained imperforate, with the attendant advantages. The attaching strip l1 may be secured by fasteners I8 to the Wood Window frame I9v Without distorting or stressing any of the cooperating parts of the Weatherstrip. Also, the Weatherstrip may be mounted Within a door frame, as diagrammatically `shown in Fig. 1, irrespective of Whether either the door or the frame or both are made of Wood or metal.

It should now be apparent that this invention attains all of its objects and advantages with a high degree of efficiency, and may be made and sold at permissible cost. Vari-ations in the construction and arrangement of the device may be made within the scope of equivalent limits Without departure from the nature and principle of the invention as defined by the appended claims.

1 claim:

1. A Weatherstrip comprising a metallic holding member adapted to be Welded to a support and having a resilient arm diverging from one edge thereof and separated therefrom by an acute angle and provided with a flange along the edge thereof extending toward said member; a resilient metallic strip comprising a flat portion approximately equal to the Width of and seated against said member, a portion extending angularly from one edge thereof and seated against the inner surface of said arm and having its edge engaging and held from displacement by said flange, a curved portion in connection With said strip laterally beyond the edges of said member and said arm, and a curved arm integrally united with said last named portion substantially covering said first named arm and separated therefrom by a space leaving said last named arm free to be iiexed toward said first named arm by pressure of the 'adjacent edge of a Window sash or door.

2. A Weatherstrip comprising a metallic holding member having a V-shape in cross-section and adapted to be Welded to a support and provided With a iiange along the edge of one arm thereof extending toward the other arm; a resilient metallic strip comprising a V-shaped portion along one edge extending into said V-shaped holding member and the edge of one arm engaging said flange, and a curved portion integrally united With said V-shaped portion of said strip laterally beyond the edges of the arms of said holding member and substantially covering said rst named arm and separated therefrom by a space, leaving said curved portion of said strip free to be exed toward said holding member by pressure of the adjacent edge of a window or door.
