WEATHER STRIP Filed July 3l, 1929 l. a /f rPaterna Nov. 11, 1930 uretra stares PATENT OFFICE JOHN a. GOELLNER, or sT. Louis, MISSOURI, assrenoa To Mortar-.lon METAL y WEATHERSTRIP CORPORATION, or sT. LOUIS, MISsOURI, A CORPORATION or MIs- SOURI WEATHER STRIP Application led July 31,

My invention relates -to metal Weather* strips of the type designed to betacked along one longitudinal margin only. 'Weatherstrips of this type are made of thin resilient metal with one longitudinal margin doubled back and bent at an oblique angle to the body of the strip to form a nailing flange and With the opposite marginal portion beaded or ldoubled back to prevent puckering and adapt it for sliding contact, the nailing iange being tacked, for instance, to thev runway of a Window frame and the free beaded edge bearing resiliently against the edge of the Window sash.

' Metal Weatherstrips of this type are used extensively; but they are open to the objection, that under certain conditions, they be- OCCHI'.

Fig. l is a cross-section of a metal Weatherstrip embodying my invention, said strip being shown interposed between the meeting edges of a frame member and the hinged or sliding closure member therefor; and

Fig. 2 isan isometric perspective of a portion of said strip.

The present Weatherstrip is made of thin resilient metal and comprises a body portion l and a nailing flange 2 along one edge there of, and a bead or doubled back marginal portion 3 along the opposite edge adapted for sliding contact. As usual, the nailing flange is bent at an oblique angle to the body of the strip, Aso that, when the nailing flange is tacked flatwise to a frame A, the body of the strip will stand out obliquely relatively to` such fiange and frame, and bear resiliently against the adjacent face of the closure member B for said fram-e.

In the ordinary resilient metal Weatherstrip of this type, the free portion thereof,

yvhen exposed to a stid breeze` or high Wind, 1s likely to vibrate after the manner of a musical reed or membrane andemit an audible sound that increases in intensity Withthe velocity` of the Wind. Besides, such Weather-` strip is usually made of such thin gagemetal that the mechanical operations necessary to form the nailing flange and the marginal bead and particularly the operation of tacking the nailing flange in place are liable to produce such buckling and internal stresses in the metal as to leave the strip in a condition to produce considerable noise in response to the shifting of mechanical stresses thereon, such, for instance, as are due to high Wind.

According to the present invention, longitudinal corrugations 4 are formed in the 1niddle Or body portion of the strip and arranged obliquely to the margins of the strip. Such oblique longitudinal corrugations are very edective in preventing the hum or singing due to the action of the strip after the manner of a reed and also in overcoming the noise arising from the buckling action. In practice, I have found the best results, in so far as concerns the suppression of noise, when the' longitudinal corrugations are arranged at an angle of about to the side margins.

As the oblique corrugations do not extend into either the nailing flange or the bead of the free margin of the strip, they do not interfere with the pivotal or hinge action of the body of the strip relative to the nailing flange that is necessary to maintain resilient control of the free edge Of the strip With the closure member. Such corrugations stiften the body portion against buckling and permit the strip to be made of a cheaper and lighter gage metal Which can beV formed with lighter and lessexpensive machinery. Such lighter gage metal is resilient enough to maintain contact with the closure member. In addi* tion to being cheaper and easier to make, the lightergage strip does not exert as great resilient pressure against the closure member as astrip of heavier gage metal Would and is therefore less liable to cause the closure membar to stick and bind or be difficult to openand c ose.
