4 Claims.
r'Ilhis >invention relates :to ‘a weather ‘strip and
a ymetlfiod vof making :the same.
It is ‘an object of 'this invention to provide `a
deflectable ‘weather .strip "that .is adapted for use
in -connection with .swinging windows, doors .or
closure `members that have a relatively .narrow
Width.
It is a further object of this invention to pro
vide a weather strip :in which the 'free contact or
l0: sealing ‘portion :will .be held .more rigidly at an
angle and attra `greater angle', and occupy less
space than `is possible v.in ‘the construction -dis
closed in my -pending application, ISerial No.
127,006, filed. February 23, i937.
“
_In accordance with this
invention, I use
sponge rubber weather strips with backings of
fabric or the‘xlike vulcanized >upon the side .faces
that `produce »excellent resiliency for ‘deiie'cting
purposes. Iitlre'n :bevel ‘or cut on. a biaszthe lower
20 rear Ymargin .of -the Weather strip and support
such weather strip upon such bevel or slope in
connection with a supporting member, so that
the free contact or sealing portion will extend
at an angle to such supporting member. I then
25 apply a clamp upon the top of the rear margin
of the weather strip, directly over the beveled
portion, and tightly screw or bolt the clamp
down and compress the beveled portion so that
the clamp assumes a substantially parallel rela
30 tion with the supporting member.
By thuswise
applying the clamp, there will be a strong oblique
tension produced in the strip that will cause the
free sealing portion or flap to assume a greater
angle with the supporting member than the one
35 produced by the bevel.
The invention comprises the novel structure
and combination of parts hereinafter described
and more particularly pointed out and defined in
the appended claims.
In the accompanying drawing which illustrates
a preferred form of this invention, and in which
similar reference numerals refer to similar fea
tures in the different Views:
Figure 1 is an elevational view of a swinging
45
or hinged window or closure member equipped
with a weather prooñng structure involving this
invention.
Figure 2 is an enlarged broken sectional View
5o taken upon the line II-II of Figure 1, looking
ln the direction of the arrows.
Figure 3 is an enlarged broken sectional view
55
taken upon the line III-III of Figure 1, looking
in the direction of the arrows.
Figure 4 is a fragmentary perspective view of
(Ul. L20-'69.)
a weather strip ksupported upon »its beveled edge
before the clamp is applied.
Figure 5 is a view similar to Figure 4 with the
clamping strip applied.
Iny connection `with this invention,` there is il
lustrated` in the `dra-Wing a Window frame I in
which a window 2 is `hinged as by hinges 2a.
The weather strips involving this invention are
adapted «to lbe attached to the-'side sash members
3 of the window and upo'n the top and bottom 10
sash members yll. It is >obvious Íthat the weather
strips 'may be requally Well applied upon the cor
responding members >of the door frame I.
The weather strips, which aregpreferably cut
to suitable lengths in accordance with the length
and width of the window, consist of -substantially
fiat sponge rubber-strips 5 with a `fabric backing
6 or other sui-tablematerial vulcanized upon the
side faces thereof to impart more vresiliency
thereto; The lower or Lunder rear ymargin of
each strip is beveled to form an oblique base or
supporting surface 1, which is free of fabric back
ing. While this bevel 'l is shown as a straight
flat cut, it may be variously formed so as to give
an initial slope to the free sealing portion When 25
-the strip is in position to be secured in place.
` In Figure 4, there is shown a weather strip 6
supported upon its bevel 1 and positioned against
a sash portion 3 of the window. It will be noted
that by thuswise positioning the weather strip
upon its bevel, the free contact or sealing portion
initially extends at an angle to such sash mem
ber.
While the weather strip is supported upon its
beveled portion, a rigid, flat clamping member 8,
which is preferably formed of metal, is super
posed over the longitudinal rear margin of the
strip directly over the beveled portion 1. This
clamping strip should be of suitable Width in
accordance with the width of the beveled portion 40
1, so that it will compress the beveled portion for
the greater part of its width, as shown in Figure
5. When the clamping strip 8 has been properly
superposed upon the weather strip 5, it is tightly
clamped down by means of screws 9 extending 45
through the clamping strip, the Weather strip,
and into the window sash 3.
The strips 8 are thus clamped down to assume
a substantially parallel relation with the sash
member 3, as shown in Figure 5. As the clamp 50
ing strip 8 is clamped down, the forward part of
the beveled portion, owing to its greater thickness,
will be compressed a great deal more than the
rear part. 'I‘he tension under which the upper
fabric 6 is placed by this 'clamping operation
2,136,687
2
causes the free sealing portion to assume a greater
angle than the initial angle caused by supporting
the weather strip upon its bevel, as is evident
from a comparison of Figures 4 and 5.
The Weather strips are similarly attached to
the sides and upper and lower sash members of
the window, so that when the Window is in closed
position the sealing portions ofthe Weather strips
will be deñected, instead of compressed.
It will be appreciated that as the sealing por
tion of a weather strip is deflected to a point
where it assumes >its initial angle’ shown in Fig
ure 4, it will offer a slightly greater resistance and
thus cause a better sealing >relation with the adja
15 cent sash member of the window.
I am aware that many changes may be'made
10
and numerous details of construction - may be
varied through a wide range Without departing
from the principles of this invention, and I, there
fore, do not purpose limiting the patent granted
hereon otherwise than is necessitated by the prior
art.
I claim as my invention:
f
'
l. In a Weather prooñng structure, a resilient
and flat weather strip having its lower rear mar
gin beveled for forming a beveled surface thereon,
a base member, said Weather strip being sup
ported with its beveled surface against said base
member and the free portion extending at an
30 angle to the base member, a top clamping mem
ber extending longitudinally along the rear top
margin of said strip and over Ysaid beveled por
tion, and means for clamping said top clamping
member against said beveled portion and bring
35 ing said top clamping member into substantial
parallel relation with saidbase member for com
, pressing said bevelled portion and causing the
free sealing portion' to assume a greater angle
than the ñrst mentioned angle.
2. In a weather prooñng structure,Y a resilient
40
flat Weather strip having its lower rear margin
beveled, clamping means for said rear beveled
margin comprising a base member, said Weather
strip having its beveled surface positioned against
said base member and a top clamping member
extending longitudinally over the top of the rear
margin and over said beveled portion of said
weather strip, and means for tightly clamping
said top clamping member against said beveled
portion for compressing the same and causing 10
oblique tension thereon for causing the free seal
ing portion to be elevated at an angle from its
initial position.
3. In a weather proofing structure, a flat strip
of sponge rubber having fabric backing upon its 15
side faces and a rear beveled margin forming a
beveled surface, clamping means for said beveled
margin comprising a base portion and a top por
tion, said strip being clamped between said base
portion and top portion with its beveled surface in 20
Contact with said base portion, said beveled' por
tion being compressed by said clamping means to
bring said clamping portions into a substantial
parallel relation and causing the free sealing
portion of said strip to move and be maintained 25
at a greater angle with respect to said base por
tion than the angle caused by said beveled sur
face.
4. In a weather prooiing structure, a resilient
flat strip having its lower rear margin cut on a 30
bevel, clamping means therefor comprising a base
portion and a top portion, said strip having its
bevelled portion positioned against said base por
tion and between said base and top portions and
means clamping said top portion upon said base 35
portion into substantial parallel relation and
compressing said bevelled portion and causing the
free portion of said strip to assume a greater
angle than that caused by the bevelled portion.
