METAL WEATHER strair.

Application filed May 28. 1923. Serial No. 641329.

To all wlwnmlt may concern:

Be it known that I, ALFRnoM. LANE, a citizenzof the United States, and a resident of the city of St. Louis, andSt-ate of Missouri, have invented a new and useful I-In- -provement in Metal Weather Strips, of which the-following is a specification. This invention relates to metal weather strips for windows. equipped withsliding sashes and has for its principal object to produce a cheap and efiieient weather strip of simple construction and compact design which can be readily applied to such win: dows without- .material alteration thereof. The inventionconsists in the parts and in "the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawing; wherein like symbols refer to like parts wherever they occur,

Fig. 1 is a fragmentary horizontal cross section through one side of a window casing and the adjacent portion of a lower sash provided with a Weather my invention; and

Fig. 2 is a hor zontal cross-section similar; to Fig. 1 showing a'weather strip of modified form.

Referring to Figs. 1 and 2 of the drawing, a portion of the casing or jamb member 3 of an ordinary window frame is shown as arranged for a sliding sash 4, the respective walls of the vertical. slideway for the sash being formed by a parting strip or bead 5 and a stop member or molding 6.-

Theweather strip shown in Fig. 1.00mprises cooperating metal strips or members .7 and 8 mounted-vertically on the jamb 3 and on the sash 4, respectively. The cooperating jamb strip 7 1s relativelyflexible or resilient and is secured along onemarginal portion to the jamb 3 of the window frame, as at 9, preferably under the stop member ormoldmg 6. silient jamb strip 7 extends between the opposing surfaces of the jamb 3 and sash t and has. its opposite marginal portion offset laterally, adjacent to the outer vertical corner of the sash, as at 10, and then doubled back upon itself for a suitable distance where itis again rebent parallel with the doubledback portion 10 and spacedtlierefrom to form an outwardly opening grooved portion llof substantially U-shaped cross-' section. The free outer margin of the restrip embodying The flexible or re-- bent portion of the resilient jalnb strip '2' is then bent at right angles to the walls of the groove to provide a flange-12. This flange portion 12 works loosely in a vertical groove 13 provided therefor between the back face of the parting strip 5 and the adjacent wall 1 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 of the groove provided therefor in the jamb 14, preferably inside of the inner face of said parting strip or head 5. The opposite margin of this rigid sash strip or member 8 is bent rearwandly at right angles to the body portion of the strip to provide a flange 15. This flange portion 15 projects into the groove portion 11 of the resilient jamb strip 7 and has a loose sliding fit therein.

In the construction illustrated in Fig. 2, the free marginal portion of the relatively flexible or resilient jamb strip 7 is bent inwardly and thence rearwardly, forming a rearwardly opening groove 11". .The metal forming the inner wall of the groove is then doubled back upon itself and is then bent outwardlyacross the bottom of said groove to -.form a flange 12 which works loosely in the groove 13 provided therefor in the window frame or'jamb 3.

The free marginal portion of the relatively rigid sash strip 8" is bent around the outer vertical corner of the sash and is then bent outwardly and thence forwardly to form a flange or tongue portion 15? which has a free sliding fit in the groove 11 in the free marginal portion of the flexible frame strip 7.

It is noted that by the arrangements described, the cooperating tongue and groove portions of the two strips are effective in preventing drafts and keeping out dust and water. It is also noted that the jamb strip, owing to its resiliency, prevents binding and maintains a' weatherproof connection be tween the two strips in the event that the sash swells, shrinks or is loosely fitted in the window frame. 7

Among the'advantages of my invention is the facility with which it may be applied; In both cases the two members forming the weather strip have a slidable weather proof directly without any alteration of the window frame or 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.

1. The combination of a frame anda closure therefor, of a mctal'weather strip comprising two coopcrating'members mounted on said frame and said closure, respectively, the frame member comprising a metal strip located between the opposing faces of said frame and said closure and having a free marginal portion doubledback upon itself and formed'into a grooved portion having one wall of double thickness.

'2. The combination of a frame and a closure therefor, of a metal weather strip com-- )risin two coo eratin members mounted on' said frame and said closure, respectively,

the frame member comprising ametal strip located between the opposing faces of said frameand said closure .and having a free marginal portion-doubled back upon itself and formed into a grooved portion having one wall of double thickness, the metal forming the other wall of said grooved portion being bent at right angles to form a flange adapted to work loosely in a groove provided therefor in said frame.

prising two cooperating members secured to said frame and said closure, respectively, the frame member comprising a metal strip located between the opposing faces of said frame and said closure, and having a free marginal portion that is doubled upon itself and is thence rebent outwardly substantially parallel with said doubled-back portion-$0 form an outwardly opening grooved portion adapted to receive a portion of the closure member.

4. The combination of a frame and a closure therefor, of a metal weather strip comprising two cooperating members secured to said frame and said closure, respectively, the frame member comprising a metal strip located between the opposing faces of said frame and said closure, and having a free marginal portion that is doubled .upon itself and 1s thence rebent outwardly substantially parallel with said double-back portion to form an outwardly opening grooved portion adapted to receive a portion of the closure member, the free outer margin of the rebent portion of said frame member being bent at right angles to form a flange adapted to work loosely in a groove provided therefor in said frame.

Signed at St. Louis, Missouri, this 14th day of May, 1923.
