METAL WEATHER STRIP.

' Application filed May 28, 1923. Serial No. 641,931.

To all whom it may concern:

Be it known that I, ALFRED M. LAnn, a

citizen of the United States, and a resident of the vertical of the city of St. Louis and State of MISSOUIl, have invented a new and useful Improvement in Metal Weather Strips, of

'which the following is a specification.

This invention relates to metal weather stripping particularly adapted for windows.

The present invention has for its principal objects to provide a cheap, simple, efficient device for weatherproofing a sliding windew and. which will not interfere with the operation of the sashes, to provide for the installation of said device without alteration of the sash or frame, to reduce the cost of manufacture, and to facilitate assembly. The invention consists principally in the hereinafter described weather strip and in the parts and in the arrangements and combinations of parts hereinafter described and claimed. I

In the accompanying drawing, wherein like reference numerals refer to like parts.

wherever'th'ey occur,

Fig. 1 is a fragmentary horizontal crosssection through one side of a window casing and the adjacent portion of a lower sash provided with a weather strip embodying my invention; and

Fig. 2 is a horizontal cross-section similar to Fig. 1 showing a weather strip of modified form.

Referring to Figs. 1 and 2 of the drawing, a ortion of the casing or jamb member 3 0 an ordinary window frame is shown as arranged for a sliding sash 4, the walls slideway for the sash being formed b a parting strip or head 5 and a sto mem er or molding 6.

e weather strip illustrated in Fig. 1 of the accompanying drawing comprises a relatively flexible jamb or frame strip or member 7 and a relatively rigid sash strip 8 said strips being mounted vertically on t e jamb 3 and on the sash 4, respectively. The jamb strip 7 is alportion to the jamb 3 ofthe window ame, as at 9, preferably under the stop member or molding 6. The jamb strip 7 extends between the opposm surfaces of the jamb 3 and sashA; and

double thickness of metal which is bent across the outer vertical corthe inwardly bent portion to secured along'one marner of the sash and formed into a hookshaped flange 10. This hook-shaped free marginal portion 10 of the jamb strip 7 is located opposite the front face of the sash; and the adjacent corner of the pai'ting head 5 is rabbeted to make room for said hook portion of said jamb strip. On the side opposite to the hook flange 10 the jamb strip 7 has its extreme free marginal portion bent substantially at ri ht angles to its body portion to provide a ange 11. This flange portion 11 works loosely in a vertical groove 12 provided therefor between the back face of the parting strip 5 and the adjacent wall of the groove provided therefor in the jamb member 3 of the window frame.

The cooperating sash strip member 8 is relatively rigid and is secured along .one margin to the outer face of the sash 4, as at 13, preferably clear of the adjacent edge of the parting strip or bead 5. The opposite free marginal portion of this rigid sash strip or member 8 is bent outwardly at right angllias to the body portion of the strip,-prefera and l S then rebent parallel with the body portion to form a hook-shaped flange 14. The hook-shaped flange pprtion 14 of the rigid sash strip 8 interloc s with the hookshaped flan e portion 10 of the resilient jamb strip and has a loose'.slidin fit therein. The rebent marginal portion 0 the sash strip 8 is spaced far enough from the body portion thereof to accommodate the rebent marginal portion of the jamb strip 7 and likewise, the rebent marginal ortion of the jamb strip is spaced far enoug from the adjacent portions thereof to accomsash strip.

In the construction illustrated in Fig. 2,

the doubled free marginal portion of the relatively flexible or resilient jamb strip 7 a is bent inwardly across the outer corner of the sash and is thence rebent parallel with form a hook flange 10. The extreme mar inal portion of the jamb strip is extende far enough beyond the body portion thereof to form a flange 11 which works loosely in the grooye 12 provided therefor in the window frame or amb 3.

The free marginal portion of the rigid sash strip 8 is offset outwardly from its body portion far enough to accommodate the flush with the end face of the sash,

I and is then rebent parallel with the offset portion but spaced therefrom far enough to enter the opening in the rebent two-ply hook flange 10 of the flexible jamb strip 7. The

loosely interlocked hook flanges of the two strips form a sliding, floating weatherproof joint that permits free sliding movement of the sash; and it also accommodates slight transverse and tilting movement of the sash relative to the frame.

, It is noted that by the arrangements described, the interlocked hook portions of the two strips are effective in preventing drafts and keeping out dust and water! Another important advantage isthat the device is not only waterproof under normal conditions but that it remains waterproof against hard rains and driving wind. Under such conditions, the force of the wind against the sash tends to force the twocooperating strips into closer engagement with each other and thus prevent storm water from being forced through the crack between the sash and the frame.

It 'is also noted that the jambstrip, owing to its resiliency, prevents binding and maintains a weatherproof connection between the two strips in the event that the sash swells, shrinks or is loosely fitted in the window frame. Another advantage of my invention is the facility with which it may be applied. In both cases the two members forming the weather strip may be applied directly without any alteration of the sash. In addition to this, my invention is very easy to make and any broken or worn part may be quickly and easily replaced.

Obviously, the invention is not limited to use with the window construction shown and described.

What I claim is: I

l. The combination of a frame and a closure therefor, of a member secured to said frame adjacent to one corner ofsaid closure, and a member secured to said closure adjacent to the opposite corner thereof,

said members having loosely interlocked portions located beyond said opposite corner of said closure.

2. The combination of a frame and a closure slidably mounted therein, of a mem ber secured to said frame adjacent to one side of said closure and having a free marginal portion extending beyond the opposite side of the closure and provided with a hook flange, and a member secured to said opposite side of said closure and provided with an outwardly offset hook flange adapted to loosely interlock with the hook flan e of said first mentioned member beyond said opposite side of said closure.

3. The combination of a frame and a closure therefor, of a member located between the frame and the end face of the closure and secured to said frame adjacent to one corner of said closure and having a rebent free marginal portion extending beyond the opposite corner of said closure, and a member secured to the side of said closure adjacent to said last mentioned corner and having a rebent free marginal portion offset outwardly from said side of said closure and slidably engaging the rebent free rmarginal portion of said frame member.

4. The. combination of. a frame and a closure therefor, of a metal weather strip comprising a flexible member and a rigid member mounted on said frame and said closure, respectively, said flexible member having a single-ply body portion located between the frame and the end face of the closure and securedto said fraine adjacent to one corner of said closure and having a double-ply free marginal portion extending beyond the opposite corner-of said closure .and loosely interlocking with said rigid member.

5. The combination of a window frame anda sash therefor, of a relatively flexible member secured along one margin to said ,frame and having a longitudinally doubled free marginal portion that projects beyond the side of said closure and is formed into a hook flange, and a relatively rigid member secured to said side of said closure and provided with an outwardly olfsethook flange portion slidably interlocking with the hook flange portion of said flexible member.

Signed at St. Louis, Missouri, this 16th day of May, 1923. I
