WEATHER STRIP CONSTRUOTIOlQ

Application January 31, 1938, Serial No. 187,794
10Claims. (01. 20-69)
This invention relates to weather strip con
struction and-particularly to a composite weather
strip adapted for use in window casingshaving
sash frames slidably. mounted therein.
One object of the present invention is to pro
5
vide a novel construction and arrangement in
weather stripping whereby sticking or binding of
in a manner to be positioned under tension be- .
the sash members or frames in their movement
in the window casing is eliminated.
Another object of the invention is to provide a
10
weather strip whereby rattling of the sash mem
bers in the window casing is prevented.
Another object of the invention is to provide
a novel construction and arrangement wherein
15 eilicient contact of the respective elements is
maintained regardless of the expansion or con
traction of the sash frames or the window casing.
Another object of the invention is to provide
a weather strip of the character described which
20 eliminates the necessity of parting strips on the
window casing, and which is adapted for use with
standard sash frames without the necessity of
extra or additional grooving of the sash.
A further object of the invention is to provide
25 a weather strip which is durable, economical,
simple to install, and which will provide a maxi
- mum of protection against weather conditions to
which the device may be subjected.
A still further object of the invention is to
30 improve devices of the character described in
sundry details hereinafter referred to and par
ticularly pointed out in the appended claims.
One embodiment of the present invention is
shown for illustrative purposes in the accom
panying drawing, in which:
Fig. 1 is a plan sectional view through a por
tion of a window casing and stops mounted there
.on illustrating the application of my improved
weather strip construction thereto before posi
40 tioning the sash frames within the window
casing;
-
Fig. 2 is a view similar to Fig. 1, illustrating
the arrangement of the improved weather strip
construction after the sash frames have been
45 positioned within the casing;
Fig. 3 is a’fragmentary perspective view of a
portion of my improved composite weather strip;
and
Figs. 4 and 5 are fragmentary perspective views,

portion of a casing member indicated, as a whole,
by the numeral 6 having inner and outer stops
1 and 8, respectively, mounted thereon, and com
prises an elongated intermediate 'member indi
cated, as a whole, by the numeral 9 and formed 5
of resilient sheet-like material capable of ?exing
respectively, of oppositely disposed angle strips
adapted to cooperate with the structure illus
trated in Fig. 3, and forming a part of the present
invention.
As illustrated‘in the accompanying drawing,
55 the present invention is shown in relation to a
tween the casing Band inner and outer sash
frames H and I2, respectively, as illustrated in
Fig. 2.
-
The intermediate member is shown, in the
present instance, as comprising‘an elongated sub
stantially U-shaped projection 13 adjacent its
central longitudinal portion to provide a hollow
parting strip adapted to be positioned between 15
adjacent end and side portions of the inner and
outer sash frames I l and i1, respectively, as illus
trated in Fig. 2, the member 9 being provided
also with oppositely disposed wing portions I4
and I5 extending laterally from the respective 20
opposite sides of the projection l3 and termi
nating slightly short of the inner and outer stops
1 and 8, respectively, in a manner. to permit a
degree of lateral ‘movement of the member 9 in
either direction with respect to the stops ‘I and 8.
Mounted in the casing 6 adjacent the respective
inner and outer stops ‘I and 8 are a pair of oppo
sitely disposed angle strips formed of resilient
sheet-like material, and indicated, as a whole, and
respectively, by the numerals l5 and H, the said
strips comprising leg portions 18 adapted to be
positioned between the respective inner and outer
stops and an adjacent sash frame to provide a
metallic wearing surface along which the sash
frames may slide, the said angle strips‘ili and I1 35
being provided with a second~~legsportion l9 ex
tending at an angle to the leg portion [8 and
adapted to be positioned adjacent .thercasing 6
and between the inner face]! thereof and the
edge portion of the wings I! and i5 formed on
the intermediate member 8, as clearly illustrated
in/Figs. 1 and 2.
'
'
It will be noted by reference to Figs. 1 and 2
that, owing to the resilient character of the mate
rial of which the angle strips l6 and i’! are 45
formed, the angle of the respective leg portions
l8 and I9 thereof will be increased from that
shown in Fig. 1 to that shown in Fig. 2, when the
sash frames II and 12 are positioned in the casing
6, thereby placing the angle strips under a ten
sion as illustrated in Fig. 2.
‘
As illustrated in the drawing, the ‘respective
wings l5 of the intermediate member 9 are pro
vided adjacent their outer edges with curved por
tions 22 forming concave surfaces on the side 55

being laterally movable with respect to said cas

adjacent the respective stops and adapted to be
engaged by the respective wing portions of said
member.

manner to iie substantially parallel thereto when
the intermediate member 9 and angle strips l6
and I‘! are in operative position with respeetto
10 the casing 6 and sash frames II and 52, as illus
trated in Fig. 2, thereby providing a most effi
cient structure to reduce in?ltration to a mini
mum and provide a maximum degree of protec

It will
