(C1. 20-69)
The present invention relates to improvements
in Weather strip construction 4for doors, Windows
and similar closures.

An object of the invention is the provisionA of
5 a Weather strip which may be attachedk to a
closure Without the use of nails or other fastening
elements.

one another.

The fastening flange ID of the Weather strip is
formed, in cross section, so that it has an in
creasing taper from the juncture With thesealing
flange to the outer free end. At the inner or
juncture end of the tapered'flange I0 isformed
Another object of the invention is the provision
of a Weather strip which may be slidably con10 nected with a closure and may be easily mounted
a more abrupt short tapering portion I2 to in
crease the flexibility of the strip at the juncture
of the flanges. The sealing flange I I is preferably 10
in position and removed.
A further object of the invention is the provision of a weather strip which may be efficiently
employed on a _straight as well as curved edge
15 closures.
still another object of the invention is the pro-
of uniform thickness in cross section from the
inner to the outer edge and usually of decreased
thiCkneSS relatiVe t0 the Complementary flange lll.
In order to properly connect the Weather strip
B with the desired edges of a door C, that is, the 15
upper and lower edges as Well as the free edge
portion, eaoh Such edge of the door is preferably
formed With a comparatively Wide Shallow groove
or channel I4 and relatively deep narrower groove
I5. The deep groove I5 is preferably formed With 20
a taper corresponding to that of the fastening
Íiange l0 0f the Weather Strip, that iS, having an
increasing taper inWardly 0f the dOOr.
To mount the weather strip B on the door it is,
therefore, merely necessary to slide the .same 25
longitudinally along the edge With the tapered
vision of a weather strip which will enable trimming or planing of the edges of a closure to correet a warped condition without removal of the
20 Weather strip.
A stili further object of the invention is the
provision of a Weather strip of the aforesaid character which will provide a durable Weather-tight
joint.

Other objects and advantages of the invén-
tion will become apparent as the description
progresses.

Referring to Figures 1 to 4 inclusive illustrating
the application of the strip to a conventional

Weather strip which is formed of resilient iiexible
material, preferably rubber. The strip B is com55 posed of a fastening flange I0 and a sealing flange

be effected without removal of the strip, due to
the peculiar connection thereof and the fact that
the blade in the plane Will not cut the rubber. 50
When, due to such trimming or to partial wear
of the weather strip it should no longer fit as
tightly as may be desired, adjustment may be
effected by inserting a filling strip I6 in the deep
groove I5 of the door, that is, between the inner 55
