COMBINED ANTIRATTLER AND WEATHER; STRIP FOR WINDOWS.

Application fl-led February 7, 1928.- Serial No. 252,500.

The present invention relates to a combined anti-rattling and draft preventing device for doors, windows and the like and has for its main object to provide metal strips for this purpose, which are so shaped and fashioned that they will practically close up all openings between the frame and the sash with out increasing the friction during the opening or closing of the latter. This obviates all use of felt or wooden strips with the accompanying swelling and: bind ing during damp weather or sticking from painting.

In order to accomplish this tightening without binding the metal strips are I'urnishedwith co-operating. tongues whi-ch tend to press the side flanges of the metal strips against the sash faces or grooves provided therein.

Another advantage over ordinary weather strips is that these metal strips are practically everlasting and consequently need no renewal and indefinitely retain their elasticity and consequent anti-rattling and draft-preventing properties.

In the accompanying drawing one embodiment of the invention is illustrated and Fig. 1 showsa transverse section through one side of the window casing andthe sashestherein;

Fig. 2, a similar section of a metal weather strip for the sides of the window;

Fig. 3, a side elevation of Fig. 2;

Fig. 4, a vertical section through the top portion of "the window casing and upper sash;

Fig. 5,. a transverse section of a metal weather strip for the top and bottom of the window and Fig. 6 a front elevation of Fig.

In the drawing, reference numeral 10' rep resents the p'ully still or jamb of the casing,

' numeral 11 the blind stop and numeral 12 the inside stop. The upper or outer sash is represented by numeral 13, the inner sash by numeral 14:, and their window panes by numeral 15. In a, rabbet 161furnished in the pulley still 10 fits a parting strip or bead 17, which projects in between and separates the two sliding sashes, while the outer face of the upper sash 13 contacts with the blind stop 11 and the inner face of the sash li contacts with the inside stop 12 in the usual manner.

The weather strip is preferably made from flexible sheet metal cut into strips and bent as best seen in'Figs. 2 and 3, into a substantially rectangular cross section which fits around the parting head 1 and in the rabbet 16. The side wall 21 of this strip is bent inwards across the parting head 17, to form a tongue 22 slightly narrower than the bead in order not to bind with the opposite side wall 23. The latter is bent outward to form a flange 24 and then doubled on itself and carried across the tongue 22, terminating with a second flange 25, the edge of which may be rolled as at 26. In thismanner the metal strip takes the form of a closed U-s-ha'ped cl-Iannel having oppositely projecting-flanges 24 and'25.

In order to increase the tightening property oi the strip, its- side walls 21 and 23 may be made slightly diverging, and the tongue 22 bent so as to exert a slight pres sure against the transverse flange 25, as clearly illustrated in Fig. 2.

The parting bead 17,'together with the metal strip 20 is secured in the rabbet 1G by means of nails or screws 27 in the usual manner. The upper sash 13 and the lower sash 14 are each provided with a longitudinal groove 28 and 29 respectively, adapted to receive the flanges and 26, as best seen in Fig. 1. As the flanges spring apart, they will tend to separate the sashes thereby, pressing them against their respective stops ll and 12, thus elin'iiua-ting rattling and all draft. I

In Figs. 4, 5 and 6 is shown how the weather strip is applied at the top' and the bottom of a window, and reference numeral 13 as before represents the upper or outer sash, numeral 30 the top jamb, numeral 31 the blind stop and 32 the top, parting bead fitting halfway down in a rabbet 33 furnished in the jamb 30.

The top weather strip 345 issimilar in construction to the side strips 20 and works on the same principle, but the side walls 35 and 36 are bent towards the middle of the channel and the wall thus forms a tongue 37 terminating with a rolled edge 38. The other side wall 36 of the strip has its bent portion 39' doubled upon itself to form a knee-shaped flange 40 hanging down substantially, perpendicular from the top jamb 30 and spaced from the parting head 32. The knee-shaped flange 40 terminates with a tongue ll preferably within the channel and has also a rolled edge 42. The latter contracts with the other tongue 37 of the top weather strip tending to press the latter tongue outwards or away from the parting bead 32, or against the face of the sash 13. The downwardly projecting portion of the knee flange 40 engages in a. narrow groove 4-2 cut in the top face of the sash 13, see Fig. 4. The parting bead 32 holds the top weather strip 34 in position in the rabbet 33 and is itself secured therein by means of nails or screws a3 in the usual manner.

It will now be evident that when the outer sash 13 is in its upper or closed position, it will be gripped tightly by the knee flange 40 and the tongue 37 but as soon as the sash is lowered it will be free from the said parts.

Likewise the T-shaped side strip will en gage with its flange in the groove 28 of the outer sash 13, on the one hand, and with its flange 2a in the groove 29 of the inner sash 14. The tongue 22 pressing against the flange 25 will then co-operate therewith to press the flanges firmly into their respective grooves in the sashes thereby preventing rattling and draft.

A weather strip 34 may also be provided at the bottom of the inner sash. 14. In that case a groove is provided at the lower face of the sash and the weather strip is placed with its knee flange pointing up instead of down as in the former case.

It is to be understood that the details of construction and arrangement of parts may be varied widely without departing from the spirit of the invention, and we do not wish to limit ourselves to such features except as may be required by the claims.

We claim:

1. A weather strip for windows and the like, comprising a folded member of flexible sheet material having a projecting side flange adapted to engage in a groove formed in the sash of the window, and means cooperating with the flange to make the flange fit tightly in said groove; said means includ ing inter-engaging wings on said flange and the body of said member.

2. A weather strip for windows and the like, comprising a folded member of flexible sheet material, said member having a channel shaped body with transversly projecting flanges, and means cooperating with the flanges to make them engage tightly in corresponding grooves of the window sashes.

3. A weather strip for windows and the like, comprising a folded member of flexible sheet material, said member having a channel shaped body with transversely projecting flanges, and means cooperating with the flanges to make them engage tightly in corresponding grooves of the window sashes, said means including interengaging wings on flanges and body of said member.

4. The combination with a window frame and sliding sashes, of channel shaped metallic weather strips therefor; each of said strips having a body portion, and transversely projecting flanges and means for flexing the flanges to engage tightly in corresponding grooves in the sashes, and a paring bead adapted to retain the body portion in a rabbet provided therefor in the frame.

5. The combination with a window frame and sliding sashes, of channel shaped metallic weather strips therefor; each of said strips having a body portion, and a kneeshaped side flange and means for flexing the flange to engage tightly in a corresponding groove in the upper face of the outer sash.

6. The combination with a window frame and outer and inner sliding sashes, of channel shaped metallic weather strips therefor; one of said strips having a body portion, and transversely projecting flanges, the other of said strips having a body portion and a knee-shaped side flange; beads adapted to retain the body portions of the strips in rabbets provided in the frame, and means for flexing the flanges to engage tightly in corresponding grooves provided in the side and top faces of the sashes.

7. The combination with a window frame and outer and inner sliding sashes, of channel shaped metallic weather strips therefor; one of said strips having a body portion and transversely projecting flanges, the other of said strips having a body portion and a knee-shaped side flange; beads adapted to retain the body portions of the strips in rabbets provided in the frame, and means for flexing the flanges to engage tightly in corresponding grooves provided in the side and top faces of the sashes, said means comprising inter-engaging wings on the body portions and the flanges respectively.

In witness whereof, we have hereunto set our hands at lVashington, D. C. this 13th day of August, A. D. nineteen hundred and twenty-seven.
