1 Claim. (Cl. 268-117)
This invention is a device for adjusting the cient stiffness to normally retain any ?exed posi-‘
sash of a casement window.
One of the objects of the invention is to pro
vide an operating device constructed of few parts,
5 which is easy to install, and which may be cheap
ly manufactured. Another object of the inven
tion is to provide an operating device of such
normal stiffness as to hold a casement window
sash in any desired adjusted position, but suf?
1 O ciently ?exible to yield if the sash should be
Such adjusting member A is preferably
electric cable,; the same being capable of‘?exing
under pressure, but having a core of wire su?i-_ Ch
ciently stiff to materially limit the degree of
?exibility. One extremity of the casing of the
adjuster member A is extended into and soldered
within a ?anged opening 20, of an abutment
plate 2|, which is secured to the sash S, by
struck by a moving object or other overwhelming
means of screws 22. In this manner the adjust~
force. A further object is to provide a sash ad
ing member is securely fastened to the window
sash‘, but is also held against rotation. The other
end of the adjusting member A is covered by a
justing device which is free of springs, gears,
rivets or the like, and in which all of the parts
‘' are ?rmly connected in such manner that loss
or displacement of any essential element is
The invention will be hereinafter fully set forth
and particularly pointed out in the claim.
In the accompanying drawing:—
Figiu'e l is a horizontal sectional view illus
trating a casement window with the invention
applied thereto. Figure 2 is a vertical horizontal
sectional view of the locking device. Figure 3 is
a detail sectional view illustrating the plate for
connecting the ?exible operating arm and the
sash. Figure 4 is a detail sectional View illustrat
ing the protecting means for the free end of the
formed of a well known type of armored ?exible
?exible operating member.
Referring to the drawing, F designates the
frame of a casement window which may be of
any suitable or desired construction. Movably
connected to one stile of the casing, by means of
a hinge H is a vertically disposed sash S, which
“ may be of any preferred structure, the same be
ing so mounted that it may be swung in a hori
zontal plane to open or shut positions, or to any
intermediate position, as may be desired.
Secured to the sill of the window frame is a
40 locking device L, which consists of a supporting
bracket l0 fastened to the sill by screws l I. Said
bracket supports a split sleeve l2, the axis of
which extends at approximately right angles to
the longitudinal median line of the sill. The
split sleeve is provided with ?anges l3 and it,
which are normally urged apart by the resiliency
of the sleeve l2. The ?ange I4 is provided with
a threaded opening, which is engaged by the
threaded end of a tension bolt l5, rotatably
mounted in the upper ?ange l3, and provided
with a squared portion 16, to be engaged by a
similarly shaped opening in an operating lever l'l.
Extended through the sleeve i2 is a ?exible
adjusting member A, which possesses ?exibility
55 but also a certain amount of stiffness i. e. su?i
spherical protecting member 23,"which is pro
vided with a recess 24, into which the adjacent
end of the adjuster member A is projected, the
edges of the opening being clamped ?rmly against
the casing with a substantially permanent en
gagement. At a position spaced from the locking 20
member L, is a retaining hook 25, which is se
cured to the sill of the window casing, said hook
overhanging said sill.
In practice, assuming the window sash to be
closed, and the sleeve L clamped around mem 25
ber A, the protected free end of the adjuster
member will be retained beneath the hook 25, as
shown in dotted lines, Figure 1. When it is de
sired to open the window to any selected degree,
the free end of the adjuster member is ?rst dis 30
engaged from the hook 25 and brought around
into such a position that member A will be
in alignment with the axis of the sleeve L. By
then pushing axially on the adjusted member,
the sash will be swung open and may be secured
at any desired angle by rotating the lever I1
sufliciently to cause the sleeve L, to clamp the
adjusted member, due to movement of the ?anges
l3 and I4 toward each other. Because of the
anchoring of the ends of the casing and the core
of the adjuster member it possesses suf?cient
rigidity to move the weight of the sash to the de
sired position, and to hold it in any adjusted
open position against the normal wind pressure
and other conditions which might otherwise tend
to close the sash. However, should a blow be
struck against the sash by a moving body, or the
sash encounter an overwhelming force of any
kind, the operating member A is su?iciently ?ex
ible to double upon itself under the strain or the
impact of the blow, so that the sash may move
toward closed position without substantial injury.
To adjust to closing position it is only necessary
to relax the tension upon the sleeve L, by proper
1 adjustment of the lever l1, whereupon a pull on
the end of the adjusting member from the inside
will draw the sash S either fully closed, or to any
intermediate adjusted position, after which the
lever I‘! is again adjusted to cause the sleeve L
to clamp the adjusting member. If the sash is
entirely closed, the free end of the adjusting
member is placed under the hook 25, so that it
will be out of the way.
The advantages of the invention will be readily
10 understood by those skilled in the art to which it
Having thus explained the nature of the inven
tion and described an operative manner of con
structing and using the same, although without
attempting to set forth all of the forms in which
it may be made, or all of the forms of its use, what
is claimed is:—
A window operating device adapted to move a
window mounted to swing in a horizontal plane,
comprising a ?exible adjusting member consisting
of a Wire cable located within a ?exible casing of 10
co-extensive length, an abutment plate adapted
to be secured to the sash and having a receiving
chamber into which one end of said casing is pro
for the operation of casement windows. An im
jected, means for anchoring the last mentioned
portant advantage is gained by the type of ad
15 justing member employed, which is sufficiently end of the ?exible member within said chamber
stiff to move the window sash, as may be required in such manner as to prevent endwise and rota
for any desired adjustments, and to normally hold ' tive' movements of the adjusting member, a ball
like handle having a recess formed therein, the
the sash open against such forces as would nor
other end of the ?exible member being in
mally tend to close it. Nevertheless, the adjust
ing member is su?iciently ?exible to yield to ab
serted into said recess, the edges of the recess be
normal pressures or shocks which might otherwise ing clamped around the adjacent end portion of
belongs. For instance, it will be observed that a
very simple and inexpensive device is provided
do injury, the ?exing of the adjusting member
under such conditions being without injury there
to, and yet serving to cushion the shock. An im
portant advantage is that the, device is free of
springs, gears, rivets and the like, and all of the
operating parts are so connected that danger of
loss or misplacement of an essential part is re
duced to a minimum.
the ?exible member in such manner as to pre
vent relative movement thereof with respect tosaid
handle, and an anchor member through which
the ?exible adjusting member is arranged to
travel, said anchor member having means for
releasably gripping said adjusting member in such
manner as to lock the same against movement,

said ?exible member being su?iciently rigid to
normally hold the sash in any adjusted position
but possessing enough ?exibility to slowly double

equally applicable to other forms of pivoted clo

as to protect the sash from injury.
