1 Claim. (Cl. 20--42)
This invention relates to weather stripping and an im
proved method of its -application about hinged window
sash and .other similarly applied closures, as -a means for
sealing the joint between the closure `and its :frame .against 10
wind and `other inclemencies of weather.
More specifically stated, the present invention pertains
to the weather stripping of wooden frames that .are litted
with easement, hopper or awning types of windows or
other similar closures mounted by foldable friction hinges. 15
In the past it has Ibeen quite diñicult to satisfactorily
weather strip windows which are equipped with those
types of foldable hinges which are gained into .the sash
and which comprise a plurality of pivotally joined links
designed to support the window sash in different positions 20
of open .adjustment and which links are adapted to fold
into side ‘by side relationship with the closing of the Win
dow; this joint sealing diiticulty being lespecially diiiicult
hinges ofthe type shown in FIG. 7.
In FIG. 4, 10 `designates the horizontal head jamb of
a wooden window frame las mounted in «a wall opening
of a Wooden building of typical construction and 1‘1
designates the corresponding top member of -a window
sash v12 that is mounted inthe frame as a closure for the
frame opening. The window of this vieW of the drawing
is, by reason of the particular manner of its hinged mount~
ing for lateral outward opening, designated -or known as
a “easement window.” The sash 12. of this view, and
also Ithose similarly designated in FIGS'. 2 and 3, is
mounted at opposite sides by hinges 15 of the kind shown
in FIG. 7; these being gained into the sash, in the manner
illustrated at 16 in FIG. 5.
The weather stripping of this invention is so applied
as to provide a tightly sealed joint between trame and
sash to the full perimeter of the sash when it is closed.
It comprises wooden strips 20 `and neoprene rubber strips
21. The Wooden strips 20 are rectangular in cross-section
and are applied entirely about the window opening except
where the folded hinge is located. They vare seated and
secured, »as best shown in FIG. 4, in the right angle corner
as formed by the frame j ambs and window stop `as applied
thereto; the strips 20 being set ilatwise against the janrbs
and all 4are formed lengthwise thereof, along their outer

pose in association with such hinges.
In view of this above mentioned difticulty and for

neoprene with tube walls 1,@2” thick a most satisfactory
seal is obtained. Neoprene rubber is an excellent insu

a temperature of 40° below zero. Such weather stripping

entirely about its peripheral edge with a continuous rab

shoulder about the sash in opposed relationship to said
stop strips, said stop strips providing hinge spaces there
in at opposite sides of the sash opening, a pair of friction
