.5 Claims. (CI. 20—49)
This invention relates to improvements in win
dow structure.
Windows of the sliding type are often difficult
to move because of tight engagement of the sash
5‘ with the engaged portion of the frame and one
of the objects of the present invention is to pro
vide a laterally extensible and retractable sash
which by manipulation may be freed from the
frame in order to more readily move the same.
Great difficulty, expense and danger of injury
is incurred in obtaining access to the outside sur
face of windows of a building structure for pur
poses of painting, repairs or washing of the glass.
An object of the present invention is to facilitate
16 access to the outer surface of sliding windows
from within the building, To this end the sash
is so mounted in the frame and so constructed
that its side portions may be disengaged from
the frame, permitting the sash to be moved en
20 tirely or partially out of the general plane of the
frame and manipulated to bring the outer por
tion of the sash within reach of a person inside
the building. A special form of such construc
tion illustrated provides a pivoted sash with re
25 tractable side portions in which the side portions
when retracted clear the frame and the sash
guides, so that the sash may be turned on its pivot
to bring the outer surface thereof within reach of
a person inside the building.
Other features of my invention comprise means
for counterweighting the sash in the usual man
ner, such counterweight means being arranged
to exert its effect on the sash at all times. Also
means is provided for holding the extensible side
35 portions of the sash in retracted position. Other
novel features reside in the speci?c construction
of the parts whereby the extensible side members
form substantially rigid lateral extensions of the
sash and prevent the entrance of weather.
Another feature of my invention is the com
bination of a novel Weatherstripping means with
a laterally expansible sash.
In the drawings, Fig. 1 is a view in elevation
of a double hung window including a frame and
45 upper and lower slidable sash members; Fig. 2
shows the structure of Fig. 1 with both sashes
in tilted position; Fig. 3 is a partial longitudinal
sectional view through one of the side rails of a
sash of Figs. land 2; Fig. 4 is a transverse sec
50 tion through a side rail and a portion of the
frame taken generally along the line 4-4 of Fig.
3; Fig. 5 is a sectional view similar to Fig. 4 show
ing the extensible portion of the sash in retracted
position; Figs. 6 and 7 are partial sectional views
similarly numbered lines of Fig. 3; Figs. 8
and 9 are detail views showing the attachment of
the counterweight cord to the sash pivot pin; Fig.
10 is a detail sectional view showing means for
holding the pivot pins in frictional engagement
with the frame; while Fig. 11 is a modi?ed form
of side member retracting means.
My invention may be adapted to slidable sash
of any sort. For instance, it is equally applicable
to metal and wooden sash and to sash of other
than rectangular form although I have illus
trated the rectangular formas it is by far the
most common type.
Pivoted sash have heretofore been constructed
wherein the stop members normally engaging and
sealing the side edges of the sash are discontinu
ous. For instance, one form of such sash'pro
vides an inner stop member on one side of the
sash pivot and an outer stop member on the op
posite side of the pivot pin. My construction is
different from this in that I provide uninter 2.0,
rupted and continuous stops on both the inner
and outer faces of the sash. Another form of
pivoted sash provides removable stop members
which must be moved when the sash is to be piv
oted. My invention differs from such construc
tion in that the stop members, bothinner and
outer, are permanently ?xed in place.
I have illustrated my invention as applied to.
25. -
a common type of window structure comprising
a frame I 0 in which are slidable upper and lower 3,0.
sashes H and. I2 respectively.
This window
structure as is usual is provided with an inner
stop [3, an. intermediate stop I4 and an outer stop
l5. All of these stops are permanently ?xed in
place and are uninterrupted from top to bottom.
The upper sash ‘slides in the frame between the
stops l4 and I5 and is provided with a sash cord
l6 which is connected to the sash H and passes
over a pulley I l and carries at its other end with
in the frame a counterweight not shown. In a
like manner the lower sash l2 slides in the groove
between stops [3 and M and has a sash cord l8
attached to the lower sash and passing over a
pulley l9 and provided with a suitable counter
While it would be possible to retract one side
edge portion of the sash su?ciently to clear the
frame and the stop members, to accomplish my
purpose I prefer to make opposite side edges of
the sash retractable as shown. The construction
here shown. is similar for both the upper and
lower sash ‘and is the same on both sides of a. I
given sash so that the construction of one side
edge portion of one of the sashes will be de
scribed, it being understood that this description
applies to all of the side edges shown. Each side
rail of the sash, as for instance the side rail 20,
has the main portion thereof cut so that the di
mension of the sash from side to side is less than
the distance between opposite stop members, that
interfering with the counterweighting as the pin
23 rotates in the loop 251).
Means is provided for extending and retracting
the strip members 2| relative to the associated
is to say, the main portion of the sash will pass
vided between the strip members and the sash
freely through the frame. Opposite side edges of
the sash are then provided with strip members
2! preferably of metal and bent so as to coact
10 with the sash in both retracted and extended po
sition so as to form substantially rigid lateral .ex
tensible portions of the main sash.
To this end, with the form of sash herein
illustrated, the sash rail 2|] is rabbeted as at 22
15 to provide a central groove extending longitudi
nally of each side edge of the sash; The strip
2| is then given a shape corresponding to the
section of the sash, as is best shown in Figs. 4
to '7. In this form of construction the side edge
portion 2! has parts 2m slidable along the inner
and outer faces of the sash rail and having a
very slight clearance therefrom of the order of
1,4;4 inch. The metal of the strip member then
extends outwardly to provide the portions 2Ib
25 which enter between the stops of the frame. The
central portion of the strip member is then bent
inwardly to provide the portions 210 which en
gage the walls of the groove 22. The walls of
the groove are substantially parallel with the
30 inner and outer faces of the sash rail and the
coacting parts of the strip 2! are correspondingly
formed so that the portions 21a and 210 engage
like portions of the sash to perform a double
function. In the ?rst place the strip is ?rmly
35 supported so that it provides a substantially rigid
extension for the side rail 29, and in the second
place the strip parts engaging the main sash
seal the structure against weather. The portions
_ 2Ic are connected by the portion Zld as indi
cated. Preferably the ends of the strips 2! are
closed in by portions Me at each end, making
the side edge portions of a strong box-like
By forming the side edge portions in the man
45 ner described, I may use a metal of comparatively
light gage, say for instance steel of 28 gage, and
the longitudinal deformations give sufficient
strength to the side edge portions that the sash
is as impregnable as the usual sash not provided
50 with my improved features.
The sash may be counterweighted in any suit
able manner but in the form shown I have pro
vided alined pivot pins 23 on opposite side edges
of the sash secured to the side rails 20 in any suit
able manner. For instance, as shown in Figs.
3 and '7, a plate 24 is secured in the sash rail
and the pivot pin is threaded in the plate. The
sash cord 16 or I8 is secured to the pivot pin 23
60 on each side, the construction being such that
the sash may pivot without disturbing the sash
cord connection. To this end the pivot pin may
be rotatable in the sash rail or the sash cord
connection may be rotatable on the pivot pin. I
65 have illustrated this latter structure wherein the
cord i6 is secured to the loop 25a of a member
25 which has another loop 252) in a plane normal
to the plane of loop 25a and within which the
pin 23 rotates. A spring clip 26 is provided to
70 hold the member 25 on the pin 23. The strip
member 2| is provided with a suitable opening
‘at 27 to accommodate the pin 23. With this
construction the strip 2| may be extended and
retracted without interfering with the counter
75 weight means and the sash may be tilted without
Inthe form shown ?at springs 28 are pro
rail in suitable number and location to bias the
strip members outwardly in a uniform manner
throughout the length of the sash. For instance
a suitable arrangement is the provision of springs 10
in the groove 22 located approximately one-third
of the distance from both the upper and lower
edges of each sash to the center, that is to say,
two springs of the type shown are provided for
each side edge portion or strip member 2| for a 15
30” x 30" sash.
Suitable means is provided for
retracting the side edge portions against the
action of springs 28 and these may be suitable
handles or clips serving to retract the side edge
portions whether or not they are provided with 20
means for holding the side edge portions re
tracted. One such construction comprises a
handle 29 having its ends connected to pins 30
extending through the sash side rails and con
nected with the side edge portions 2!, as for in 25
stance by the enlarged heads 3!. Upon pulling
of the handle 29 inwardly, the connected side
edge portion is retracted.
A simple means for holding the side edge por
tions retracted is shown in Figs. 4 and 5 where 30,
cam portions 29a are constructed rigid with the
handle 29. As the handle is pivoted about the
pivot connection 35311 with the pins 30, the cam
portion 29?) engages against the side rail of the
sash and holds the side edge portions 2! in re 35
tracted position as shown in Fig. 5. It will be
obvious that with the side edge portions 2| in
this retracted position they are drawn in sui?
ciently to clear the stops M and IE or [3 and M
as the case may be, permitting the sash to pivot 40
about the pins 23. Each sash may thus be turned
inside out, giving easy access to the outer portion
of the sash from the interior of the building.
When the side edge portions are again extended
they engage within the frame It] and support
the sash for the ordinary sliding movement.
Combined with my laterally extensible sash
I may provide a very ef?cient weather strip.
This is indicated in Figs. 4 to 7 and may com
prise one or two L-shaped metal strips 32 having 50:
a leg 32a secured to the frame H) and a leg 32b
yieldingly engaging against that portion of the
strip member 2! which extends inwardly to pro
vide the portions 210. A seal is thus provided at
the point 32c in any of the adjusted positions of 557
the sash and, as illustrated, with two such
weather strip members 32 a double seal is pro
Means may be provided, if desired, to hold the
‘pivot pins 23 in place relative to the frame while 60
the sash is pivoted. One such device is shown at
33 in Fig. 10. A thimble portion 33a. of the de
vice embraces the end of pin 23. A base portion
331) comprises a plate narrow enough to ?t be
tween the strip portions Zlc and as long as de 651
sired. A spring 34 biases the device 33 into fric
tional engagement with the frame If).
A modified form of side-portion retracting
means is shown in Fig. 11. Spaced along the
sash rail are the members 35. The retracting m1
pin-3E! has the same function as the pins 30 pre
viously described. A projection 36 at the inner
end of the pin enters the cam slot 3'! in slide 38.
This‘slide has guides 39 secured to the sash and
may be moved by handle 40. By pulling the slide
downward the pin an is cammed inward and re
tracts that portion of member 2| connected
therewith. These devices 35 render it easy to
retract the side edge portions and to hold them
retracted while the sash is tilted.
