GASKET STBIPPING
Woodward L. Harlow, Newton, Mass.
Application December 23, 1935, Serial No. 55,782
11 Claims.
This invention relates to gasket stripping which
may be used, for example, for weather stripping
of windows and the like, sealing of man and
hand hole covers and the like, and while not re
6 stricted thereto, has been developed more par
ticularly to meet the exacting requirements of
casement windows, and where the frame parts are
metal, such windows presenting extraordinary
difficulties to satisfactory weather stripping,
which have hitherto not been satisfactorily met.
In such windows the sashes may at some parts
make metal to metal contact with the casement
frames when the windows are closed normally,
and at other points these parts may be spaced
apart. Any satisfactory continuous gasket strip
of uniform cross section must, therefore, be able
to effect a weather-tight joint where the parts
are spaced and yet not extend between the sash
and its casement frame and prevent contact
where there is such contact in the normal closed
position of the window. This non-interference
with metal to metal contact is of very great im
portance, particularly where such contact occurs
near a hinge axis of the window since any ob
‘5 struction to complete normal closing here would
cause a much greater failure to close remote from
the hinge axis.
One of the important objects of the present
invention, therefore, is to provide a construction
of continuous gasket stripping whereby when ap
plied, metal to metal contact is permitted wher
ever it will normally take place and wherein the
parts will be sealed where such contact is not
present.
,
'
A further object is to provide a construction
wherein any deformation of the strip in use will
be ineffective to pull the strip away from the part
to which it is secured as by cement.
' A further object is to provide a stripping con
struction which will be effective where the rela
tively removable window or like parts have rela
tive sliding motion as closed position is ap
proached.
A further object is to provide a weather strip
ping construction which will be serviceable in
use.
Further objects and advantages will appear
from a more complete description of certain em
50 bodiments of this invention shown in the accom
(CI. 20-69)
showing various forms of strip illustrating this
invention.

Figure 9 is a section through a window sash
and its casement frame showing the action of a
strip like Figure 2 in effecting a weather-tight seal
when the relatively movable parts are out of
contact when the window is closed.
Figure 10 is a view similar to Figure 9, but
showing the frame parts in contact, and
Figures 11 and 12 are sectional views somewhat 10
similar to a portion of Figure 9, but showing the
window partly open and closed, respectively, and
using the stripping of the form shown in Figure 6.
Referring first to Figures 1, 9 and 10, at I is
indicated the side frame portion of a casement
window, this frame portion I, as shown, being of
substantially 2 cross section. Cooperating with
this casement frame is a sash frame 2 also of sub
stantially 2 cross section and carrying between
the angularly disposed walls 3 and 4 a retainer
5 to hold the pane of glass 6. The frame 2 is
shown as pivoted to the frame I as by the hinge
‘I. In closed position of the window so con
structed, the ?ange 4 of the window may at cer
tain' points contact with the face III of the ?ange
ll of the frame member I and at other points
it may be somewhat out of contact with this face
when the window is closed.
In accordance with this invention stripping is
so applied that where the ?ange 4 may, in its 30
normal closed position, contact with the face II),
it is permitted to do so, but where this ?ange 4
is spaced from the face I0, it is sealed in weather
tight relation thereto. Stripping suitable for this
purpose is shown in Figures 2 to 8. In Figure 2,
this stripping comprises a body portion I5 of
soft yieldable material such as sponge rubber,
though it might be extruded or otherwise formed.
It is preferably reinforced at both top and bot
tom faces with a non-extensible but flexible ma
terial such as cloth, as at I6 and II. The base
face at I 6 is preferably coated with a suitable
adhesive by which the stripping may be secured
to the face III of the easement frame and this
may be protected by an additional tape which
may be removed, when it is desired to apply the
stripping in position, to expose the adhesive, as
shown, for example, in the Brown Patent No.
1,960,137 granted May 22, 1934. Unlike the
structure of the Brown patent, however, the 50
outer face of the body is likewise preferably pro

mating surface contains oil, as when somewhat
recently painted. The side face of the body
member i5, which may be termed the forward
face, is shown as recessed at I8 so that the body
strip is channel shape in cross section and, for
a purpose which will later appear, the upper por
tion of the body is partly cut away from the
‘tower portion as by means of a slit I9, leaving a
neck of uncut material as at 20 between the inner
10 edge of the slit I9 and the recess I 8. The body
strip may be cut of rectangular cross section
from a sheet of materiai of a thickness equal to
the height of the strip and provided with a fabric
reinforcement on opposite faces, after which the

somewhat on the exact placing of the strip as
secured to the frame member I.
In some instances there is more or less relative
lateral motion of the'cooperating frame members $1
when approaching closed position. For example,
there is some such motion on the left in the con
struction shown in Figures 9 and 10, due to the
relative angular motion of these parts on the
hinge ‘I, and this neck portion 20 furnishes a 10
yielding connection between the head and the
base of the strip which yields to this motion, per
mitting the head portion to be rearwardly offset
relatively to the base, the engagement of the
recess I5 and the slit I9 may be cut therein. '

The strip such as shown in Figure 2 is cemented

frame member 3 when this member is in closed

In Figures 3 to 8, other forms of stripping
which may be employed in accordance with this
invention are illustrated. These may be made of
outer edge of the base portion 2i of the strip is ' sponge or xtruded rubber with or without a
positioned at one side of the angularly disposed sponge rubber lower face, if desired, or in thin
outer faces of the wall members 3 and 4, which, sections even from metal or in combination with
as usually constructed, meet each other in an metai. In Figure 3 the stripping is. shown as
25 outwardly extending bead portion 22, the strip
formed of readily deformable material such as 25
being so placed that this bead portion 22 engages
the upper lip portion 23 of the gasket strip above
the recess I 8, this lip being spaced from the base
portion and extending toward the forward edge
30 thereof. Thus, when the parts 2 and I fail to
make metal to metal contact when the window
is closed, as shown in Figure 9, the lip or flange
portion 23 makes sealing engagement with some
part cf the bead portion 22, either bearing on
the top face thereof, as shown at the right hand
sponge rubber reinforced at its top and bottom
faces as by the fabric I‘! and I6, as in the con
struction shown in Figure 2,\but the recess in
the forward face is shown as angular as at I 8a,
forming the lip or ?ange portion 23a similar to 30
the corresponding part of the construction shown
in Figure 2. Stripping of this form also, is pro
vided with the slit IS in its rear edge for the
same purpose as for the construction shown in

of this lip 23 bears on the outer face of the bead
22, as shown at the left end of Figure 9. It will be
40 noted that where the member 2 strikes against
the upper face of the lip, it tends to rock the
upper or head portion of the strip about the resili

is shown as made of a separate membenfrom 40
the body portion 3| and is secured thereto. The
head portion in this construction has the for
ent neck portion 20. The provision of the slit I9
prevents this rocking from being transmitted to
the base portion. 3i and the base portion 3i is
the outer or rear edge of the stripping in a man
provided with the slit I9
ner tending to lift it away from the surface I0,
which would be likely, if permitted, to cause the
stripping to be pulled away from the surface I0
after some period of use. This slit I3, however,
.50 affords a yielding neck portion for supporting
the upper or head portion of the stripping which
can yield or bend without tending to pull the
rear edge of the stripping away from the surface
to which it is cemented. It also provides for a
55 portion of some substantial width of the full
thickness of the strip material presenting a top
face for engagement anywhere within this width
by the relatively movable frame member, thus
providing for commercial variations: in such

tion also affords a more susbtantial lateral sup
port for the lip 23. Preferably also the lips 2I
and 23 are tapered outwardly so that they more
nearly conform under pressure to the shape of
the bead portion 22 which may contact therewith,
thus to increase the area of such contact and the
completeness of sealing.
In Figure 10 is shown the position of‘ the strip
35
wardly extending lip 230 which extends beyond
its rear face as in
the constructions previously described. This is in
e?ect the same as though the base were cut back
to the ‘depth of the recess in the forward side
face of the strip.
'
In Figure 6, a somewhat different construction
is employed preferably made of extruded rubber.
This includes a ?at base portion 35 from which
extends a yieldable neck portion 3-6, preferably
placed inwardly from opposite edges 31 and 38
of the face portion 35, although with a relatively 55
long neck, such as shown, the stresses which
would otherwise tend to lift the back edge of
the base portion 35 may be sufficiently taken care
of in the length of this neck without requiring
any extension of the, base portion back of the 60
root of this neck. This neck also carries at its
upper end a head portion 39 having the for
wardly extending lip or ?ange 23d which is
spaced from and extends over toward the edge 38
of the base member. This head member may also 65
extend rearwardly of the top of the neck portion
36 as shown at 4.0 in order to impart a desirable
lateralsti?ness to the head and width of top
ping where the frame member 2 may make metal ' face for engagement by the movable frame part,
to metal contact with the ?ange member I I. The although in some cases this may not be important 70
lip 23 then engages the bead portion 22 either on
or back of the face 4 and may ride up more or
less onto the outer face of the portion 3 either
above the bead portion 22, as shown at the left
75 end of Figure 10, or on the outer face thereof, as
and may be omitted. If desired, the upper and
lower faces of this strip may be reinforced with
fabric, but if it be made of extruded rubber it is
not so important that the upper face be so rein
forced. The reinforcement of the lower face has
3
2,122,608
for one of its objects the prevention of the se
curement of the strip in stretched condition, the
recoil tendency tending to release the securement
of the strip in position, or to cause it to draw
back so as not to produce weather tightness for
the full length of the cooperating window parts
and this upper face reinforcement also aids in
these respects.
In Figure 7 is shown a construction wherein
the forward face of the strip is cut back on a
bevel to its base, so that in effect the forward
\face is recessed and the base cut back, as men
tioned with respect to the construction shown
in Figure, 5. The rear face may be complemental
ly beveled to produce a wider securing face and
to save waste in cutting. The ?at cut is easier
to produce than a out such as shown in Figures
2, 3 and 4 arid it results in a construction which
presents a lip or ?ange 23c spaced from the base
which acts similarly to the corresponding part
of each of the constructions hereinbefore de
scribed.
Figure 8 illustrates a construction particularly
suitable for production by extrusion. It may be
extruded as a complete tube with or without a
thickened side portion to form a base 45 and the
part between the edges 46 and 41 may then be
cut out to leave the arcuate portion 48. If the
thickened portion to form the base is not initially
30 formed, it will usually be found desirable to se
cure a suitably shaped part to the tube to form
such a base before the tube is cut to form the
edges 46' and 41. The portion adjacent to the
edge 41 of this construction serves as a lip or
35 ?ange spaced from the base for sealing engage
ment with one of the parts to be sealed, this part
tending to coil to a shorter radius when pressed
upon by such part, that part of the tube toward
the base serving as a resilient neck between the
40
base and the head portion spaced from the base.
In Figure 11 a strip such as is shown in Figure 6
is shown as secured in position on the face ll)
of the casement frame. The lip or ?ange portion
23d extends over in position to be contacted by
the part 22 of the frame member 2 before this
frame member contacts with the face Ill so as to
effect sealing engagement therewith should it
fail to reach actual contact with the face ID in
normally closed position, but permitting such
actual face to face contact where the construction
and relation of the frame parts will allow this
in the ?nal closed position.
Figure 12 shows this sealing of the strip to the
member 2 while this member 2 is still spaced
somewhat from the face Ill.
While this stripping is shown as applied to a
single form of window, it will be evident to those
skilled in the art that it may be applied in a
