Application March 19, 1937, Serial No. 131,912
1 Claim. (Cl. 292-18)
This invention relates to combined weather
‘strips and sash control means, the principal ob
ject being to provide practical means for verti
cal control of a window sash without the necessity
of weights and at the same time produce an
adequate weather strip.
Another object is to provide such a device con
veniently manipulated by hand to increase or
diminish the eiiiciency of same as a sash control
' means, particularly to compensate for varied re
quirements in respect to the weight of the window
to which it is applied.
Other objects and advantages of the invention
will appear in the following description thereof.
Referring now to the accompanying drawing,
forming part of this application, and wherein like
reference characters indicate like parts:
Figure 1 is a perspective view of a. fragmental
portion of the outer edge of the window sash
having one embodiment of the invention attached
Figure 2 is a. perspective view of the crank
member for adjustment of the device.
Figure 3 is an end view of the two cooperative
clamping members in the device.
_ Figure 4 is a perspective view of a fragmental
portion of the weather strip and clamp engaging
tongue or bead.
Figure 5 is a somewhat enlarged view of the
clamping unit assembled ready for installation.
Figure 6 is a perspective view of the adjusting
Figure 7 is a perspective view of the clamp
spring and pintle.
Figure 8 is a transverse sectional view of the
clamp member just inwardly of their supporting
I represents a portion of a common window
sash, however having a groove or channel 2
formed centrally of the jamb engaging face, and,
preferably about centrally of the vertical height
or the sash is formed an enlargement 3 of the
slot providing a pocket for my improved control
lips are perforated to receive the pin 8. The lips
on one of the clamping members (immaterial
which) are of less distance apart than the other
member so that they ?t one within the other as
clearly shown in the drawing.
About the pintle 8 and intermediate 0f the lips
or bearings II of the smaller member is installed
the spring I2, the termini of which are given
several turns about the pintle 8 adjacent its ends
and then extend outwardly to provide adequate
bearing against the inner walls of the body por
tion 9 of the clamping members to bias them out
wardly, which results in the lips III of the clamp
ing member being biased inwardly for the pur
5 of
of frictionally engaging the bead or tongue 15
the weather strip 4 when engaged thereby.
adjusting means for these clamping mem
I have illustrated the interior of the body
portion of one of such as being provided with a
slight enlargement or hub-like portion I3 having
a hole therethrough internally screw threaded
for the reception of the bolt I4 which is provided
with a ?ange I5 upon its outermost extremity.
From the center of this ?ange extends the
rectangularly shaped projection or head I6 to 25
which the crank I‘! may be applied as noted in a
selective position as the hole in the crank for
such engagement is of the form of a Greek cross
permitting of its being applied in various radial
positions in respect to the bolt. Obviously the
clamping members are installed in the pocket 3
before the bolt I4 is applied thereto, and there is
a hole through the innermost wall of the sash I
for registration with the holes in the body por
tions of the clamping member.
after such installation and that of the bolt I4
and of the escutcheon plate I8 mortised within
the face of the sash, it having the depressed
socket I9 therein suf?ciently large to receive the
?ange I5 of the bolt H, the latter being sul?
ciently long to reach to the screw threaded por
tion of the farthest clamp body portion, when the
means and on the face of the sash runway in the
bolt is screwed in it will tend to draw the body
jamb is attached in any desired manner the
combined weather strip 4 and track, the track
portion of the bead being indicated .at 5.
The clamping unit is carried within a U-shaped
supporting member 6 of ?at bar metal having
portions of the clamping members together, thus
the parallelextensions ‘I thereupon in which is
installed the clamp supporting pintle 8. The
clamping members comprise the body portions 9
and clips III, each clamping member having ap
proximately centrally thereof a turned in lip in
dicated at II on either edge thereof and which
opening the lips II) of said members to any de In
sired degree depending upon the pressure of the
adjusting screw. 'I‘hus such frictional contact is I
designed to fully compensate for the gravitating
tendency of the window, and there may be such 50
connections upon one or both sides of each
window sash as desired.
To augment the frictional contact of the lips I 0
upon the bead 5 of the weather strip I have
shown it as being provided with a series of per- 55
foretions 2% which is deemed. to sumce for such
increase of the ‘frictional contact.
If preferred, when these weather strips are
made, the perforations may only be formed in one
CR sicle of the head 5 to provide against lessening
the function or this member as a weather strip.
A sash control for windows having longltudi=
nal slots in its side edges for cooperation with
weather strip elements, said sash control com
prising spring biased clamping members pivoted
together between their side edges, and carried by
the sash and adapted for frictional engagement
It is to be understood that various departures
from the smci?c construction shown may be re
upon opposite sides of the extending portions of
said weather strip elements, and a bolt extend
sorted to without department from the spirit of
ing through one of said members and screw
threadedly into the other for regulating the Korea 10
the invention, and the combination 0f elements
set forth in the appended claim.
Having thus described my invention, what I
claim and desire to secure by Letters Patent, is:
of said spring.
