UNITED STATES PATENT oFFifvcE-f WEATHER STRIP Charles P.v Schlegel andA Norman C. Schlegel,

Rochester, N. Y., assgnorsl to The Schlegel Manufacturing Company, Rochester, N. Y., a

corporation of New York Application September 14, 1939, Serial No.29f1,874 4 claims.

One de-"U therethrough into the supporting` surface, as

sirable material for such filler strip has been shown, and in any longitudinal .spacing which 55 may be required to secure the windlace in place.

Another important principle of the present invention is embodied in the provision of a construction for the attaching flange which allows it to be resiliently extended or stretched in a longitudinal direction. This is accomplished by forming in the fabric layers of the attaching flange a series of longitudinally spaced pairs of slits I1, Fig. 2, extending inwardly from the marginal edges of the fabric adjacent the filler strip. 'I'he slits of' each pair are arranged oppositely or in coincident relation in the fabric layers II and I2, respectively. They maybe preformed in the fabric before assembly inthe windlace, or, in the embodiments shown in` Figs. 1-3, they may be cut therein while the latex layer I3 is still soft and tacky so that the latex on opposite sides of each slit will reunite with itself before vulcanization to maintain the longitudinal continuity of the resulting rubber layer.

This flange enables the windlace to be curved uninterruptedly around a corner or curved portion of a door opening or other joint, as shown in Fig. 2, the supporting flange being on the outside of the curve, as shown. The rubber layer stretches resiliently between the sides of the slits II which separate, as shown at I'Ia, and such yielding of the attaching flange allows the body portion of the windlace to be curved uninterruptedly in desired position, while the supporting strip remains in flat and smooth condition on the surface to which it is attached. The body portion thus serves, in effect, as the neutral axis of bending, with the tension in the flange which stretches to accommodate it. The construction thus obviates the sliding of the filler strip 9 in the cover fabric, or the cutting away of portions of the filler strip, or other expedients heretofore found necessary in prior windlace constructions for bending smoothly around angular or curved joints to be sealed. f

In Fig. 3 is shown a somewhat modified construction of the windlace comprising the saine parts, but with the fabric layers II and I2 and the rubber layer I3 arrangedl in a generally tangential relation to the body portion 9, as desirable in some installations, particularly where the surface to be engaged by the body portion is depressed below `that to which the windlace is attached, or to increase the sealing pressure of the body portion, or meet other special conditions. This modiiication is assembled and applied in use as already described in connection with that shown in Fig. l.

In Fig. 4 is shown a still further modification in which the filler strip 9 and cover fabric I0 are the same as those described in connection with the modification of Fig. l but in which the rubber layer, instead of being applied as a latex coating to the inner surfaces of the cover fabric, is in the form of two preformed sheets of rubber, I 8 and I9, which are interposed between the fabric layers II and I2 of the supporting flange and extended part way between the filler strip 9 and the cover, as at 20. These rubber sheets are preferably caused to adhere to each other, the cover fabric, Aand the filler strip 9, by the application of a cement or solvent of any known or suitable variety, Aas well understood in the art, and, in addition, the fabric and rubber layers of the attaching flange may be'secured together by a line of stitches 2l parallel with the filler strip 9. Such stitching, of course, may be employed also in the modifications of Figs. 1 and 3, if desired, to more securely unite the parts. In this embodiment, the attaching flange is disposed radially and concentrically of the filler strip as in the modification of Fig. 1, but it may, of course, be arranged instead in the tangential position illustrated in Fig. 3. It is to be understood, of course,

that the slitting of the attaching flange, as described in connection with the modification of Fig. 1, may also be employed in the constructions of Figs. 3 and 4, as actually indicated in Fig. 4 by the location of the sectional view at one of such slits.

It will thus be seen that the invention accomplishes the objects stated above. The body portion is of asoft, resilent material adapted to conform in close sealing contact with one side of the joint to be closed. The rubber layer of the attaching flange affords a high degree of resilience for holding the body portion of the windlace in sealing position, and the characteristics of this rubber material are of a nature to maintain such resilience with substantial permanency. The provision of a longitudinally resilient attaching flange facilitates even and uninterrupted application of the body portion in the desired sealing position, and smooth and flat attachment of the flange to the supporting surface, in a unitary construction and association of the parts which can be quickly and conveniently applied in use.

The invention has been herein disclosed by way of illustration, in several embodiments thereof, and it is further contemplated that other modiflcations of the construction and arrangement of parts may be employed within the scope of the appended claims.

We claim:

l. A windlace comprising a flexible elongated filler strip, a strip of fabric folded around said filler strip with its marginal edges extending laterally from said filler strip to provide an attaching flange, and a layer of resilient rubber interposed between the fabric layers of said flange and united thereto and with said filler strip, said rubber layer beingccntinuous but the fabric layers of said flange having spaced coincident slits ex.

tending inwardly from the edges thereof toward said filler strip so that said flange may be resiliently extended longitudinally to accommodate bending of said filler strip.

2. A windlace comprising an elongated exible filler strip, a fabric cover enclosing said strip and having its marginal edges extended laterally thereof to form an attaching flange, and a layer of resilient rubber interposed between the fabric layers of said flange and united therewith and with said filler strip to provide in said flange a unitary resilient support for said strip, said rubber layer being substantially continuous longitudinally of saidstrip but the fabric layers of said flange having longitudinally spaced pairs of oppositely arranged slits extending inwardly from the edges thereof toward said strip for resilient longitudinal extension of said flange during bending of said filler strip. i

3. A windlace comprising an elongated filler strip of relatively flexible soft material, an elongated cover strip of textile fabric extended around said filler strip and having its marginal portions extending laterally from said filler strip to prov.de an attaching flange and a substantially fiat layer of resilient rubber interposed between the fabric layers of said flange and vulcanized thereto and to said flller strip to render said flange resilient and integral with said filler strip, said rubber layer being substantially continuous longitudinally of said strip but the fabric layers of said flange canized thereto and to said filler strip to provide an integral resilient attaching flange, said rubber layer being substantially continuous longitudinally of said filler strip but the fabric layers of said ilange having spaced longitudinally thereof a series of pairs of opposite slits extending inwardly from the edges thereof toward said filler to provide for resilient extension of said ange to accommodate bending of said filler strip.
