WEATHER STRIP.

Application filed January 19, 1924.

My invention relates to improvements on weather strips. One of its objects is to provide an improved sheet metal weather strip adapted to be applied to windows, doors, and

similar openings where it is important to exclude the passage of water and cold air at the joints during cold and wet weather. An-

other object is to provide an improved all metal Weatherstrip adapted to more perfectly close the joints and exclude rain and cold air. Another object is to provide an improved weather strip adapted by its outline, shape and relation of parts to more per fectly and persistently retain its original outline and to thereby more perfectly perform its function and for longer periods of time, and to more perfectly meet the varying conditions of practical application. My invention also comprises certain. details of form and combination of components, all of which will be fully set forth in the description of the accompanying drawings, in which:

Fig. 1 is a perspective view of a section of sheet metal weather strip embodying my invention.

Fig. 2 is a horizontal section through one side of a window frame and sash illustrating the application of my improved weather strip thereto.

Fig. 3 is a horizontal sectional detail through one side of a door frame and door illustrating the application of my improved weather strip thereto} Figs. i and 5 are sectional details illustrating the range application of my improved weather strip.

The accompanying drawings illustrate the preferred embodiment of my invention in which the weather strip is formed by bending or folding uoon itself a relatively narrow strip, of resilient sheet metal or other resilient material longitudinally thereof along a line 20. The line is preferably so located with reference to the width of the strip that a relatively narrow leaf or blade 22 is preferably bent outwardly from the base sections 21 along the line 40 and is adapted to bear yieldingly against one face of the joint, say against the face 24 of the window frame 25. In Fig. 2 a relatively wider leaf or blade 26 is adapted to bear yieldingly against the opposite face of the joint, say against the face 27 of the window sash 28.

In order that the leaf 26 may be better Serial No. 687,339.

adapted to retain its shape, and also that it may engage more perfectly and satisfactorily with the joint to be closed, and in order that it may more perfectly engage and disengage with the joint to be closed where such action is required, said leaf 26 is curved transversely of its length into substantially a section of a cylindrical body, and at its free end 30 is preferably turned upon itself to provide a smooth binding or finished edge adapted to slide freely along either face of the joint to be closed, without liability to catch or bind thereon. Thus where the joint to be closed is narrow the middle section of the curved leaf 26 is adapted to engage firmly against one face of the joint, say the face 27 of Fig. 2, while the two opposite edges 30 and 2-31 of said curved leaf both tend to react against the pressure on the joint face 27 and to press against the joint face 24: to doubly and more effectually close the joint between the sash and window frame. Substantially the same action will be had to close the joint bet-ween a door and door frame as shown in Fig. 3 for instance:

The base member 21 serves as a point of attachment for the weather strip, which is preferably effected by means of screws or nails 23 passing through perforations in the base member 21 at intervals and into the window frame or door frame. Normally the spring action of the leaf 22 is to lift the base of the leaf 22 along line 40, and also the base of the leaf 26 at 31 away from the face of the joint to which the base member 21 is attached by the screws 23 and thereby affords a more resilient hearing or contact of the leaf members 22 and 26 against the opposite joint surfaces, and thereby affords a more effective and perfect weather protection'than would be otherwise attainable.

iVhcre, however, the joint to be closed is relatively wide, as shown for instance at Fig. 5. a portion of the curved face of leaf 26 will bear against one joint face 32 and the base of the leaf 26 at 31 will bear in directly against the joint face 33, while the end, 30 of the leaf 26 will remain out of contact with the joint face 33. The curved outline of the leaf 26, as indicated in Fig. 3, tends to more readily make and break the joint between the free or moving edge or face 35 of a door and the face 36 of the jamb of the door frame 37, substantially as above described, to secure either a single or double engagement of the leaf 26 i l curved or (;".lll1-il i "l outline ot the lent ana s "Hill lea l' to selectively make roata 't at (Ellerent poin s along' its curved lace. and tends in prev nt dents being toranc in the ta e lherwtJand tends to sernre torn; and continnons engagement (i' a l e-:1." w th one or hoth ot the ta s o 2' r to l? clef (l even though the joint 1" -.i la: one end than at he other. he inntna ion ot the two diiewz ng resilient leave. and 2e and their uniting and 1.1;: aaanher is such that said meml ers do not lose thei re iliency in nse. even nnder severe and 'epeatezl pressure or slraiin and hence retaii and return to" l J l i nal positionfn ien strain thereon 'lhe positions oi the strip in their om.
