PROVISIONAL SPECIFICATION.
Improvements in Stays and Fasteners for Casement Windows.
I, HARRY HARDY, of 9, Grosvenor Road, Swanage, in the County of Dorset,
Plumber, do hereby declare the nature of this invention to be as follows:-
My invention relates to stays and fasteners for casement windows.
According to my invention the stay rod is provided with a ball working in a
socket joint adapted to be secured to the window or casement and in order that the
rod may be secured in any position it is adapted to slide through a guide having
within it a projecting tongue or rib engaging with correspondingly shaped notches
formed in the stay-bar. Inside the guide is also arranged a spring which presses
upon the bar in such a manner as to prevent the said bar from slipping out of
engagement with the tongue. In order to move the bar in the guide for the
purpose of adjusting the window it is only necessary to raise the bar against the
pressure of the spring to prevent the notches from engaging with the tongue.
The fastener is a simple lever pivotted to a plate adapted to be connected to the
window the said lever having in it a notch for engaging with the window frame or
with the adjacent casement. A spring normally holds the lever in its locking
position whilst allowing it to spring back sufficiently to allow the opening and
closing of the window.

COMPLETE SPECIFICATION.
Improvements in Stays and Fasteners for Casement Windows.
1, HARRY HARDY, of 9, Grosvenor Road, Swanage, in the County of Dorset,
Plumber, do hereby declare the nature of this invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
My invention relates to stays and fasteners for casement windows.
According to my invention the stay rod or bar is provided with a spherical end
or ball working in a socket adapted to be secured to the window or easement or
with some other system of universal joint and, in order that the rod or bar may
be secured in any position, it is adapted to slide through a guide having within it a
projecting tongue or rib or its equivalent engaging with correspondingly shaped
notches, holes or the like formed in the stay bar. In some cases employ a spring
or weight to keep the tongue or its equivalent in engagement with the stay-bar.
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawings, in which :-

right angle to Figure 26 and shewing the stay-bar and weight arm of the guide in
cross section.
Similar letters in all the figures indicate similar or corresponding parts.
I will first describe my invention by reference to Figures 1 to 7.
a is the socket secured to the window or casement &; c is the stay-bar, and dis
the ball thereon working in the socket a. The stay-barc is formed in several
pieces jointed together at e, e, so that while forming a rigid stay when requiring to
secure a casement window in an open position as shewn in Figures 4 and 5, the
part which is not being used as a stay can hang down vertically and thus be out of
the way. The end part or link of the stay-bar c, on which the ball d is fixed or
formed, is preferably made shorter than the other sections or links so as to allow
of the window being secured when closed and still avoid any inconvenient
projection of the stay-bar e as clearly shewn in Figure 2.
is the guide for the stay-bar c, the said guide being pivotted in a bracket
screwed to the window frame h; is the slot in the guide, through which the
stay-bar e passes; is the tongue or rib on the guide f, and are the notches in the
stay-bar in which the tongue or rib j engages.
is the spring which I employ in this arrangement for keeping the tongue in
engagement with the notches in the stay-bar, the zaid spring being located in a
tubular portion of the guide. This spring transmits its pressure to the bar
through a roller n which bears upon the bar and is carried in a bearing o which
receives the pressure of the spring. The spindle of the roller extends into
slots in the guide, which slots allow of the vertical movement of the bearing, and
at the same time prevent it from rotating.
With this construction in order to move the bar in the guide for the purpose
of adjusting the window b, it is only necessary to straighten the bar and raise it
against the pressure of the spring to prevent the notches & from engaging with
the tongue; by then dropping the bar it will engage with the tongue and hold the
window securely in the position to which it has been moved.
The arrangement illustrated in Figures 8 to 12 is substantially the same as that

page_text: hereinbefore described with reference to Figures 1 to 7 but the use of a spring is
dispensed with, the mere weight of the stay-bar c causing it to engage with the
tongue or projection which, in this case, is formed in the middle of the guide
and enters spaces k between distance-pieces r, r fixed in the bar c.
In the arrangement shewn in Figures 13 to 17 the tongues or ribs are placed at
the sides of the guide and enter notches in the top edges of the bar which is
made T-shaped in cross section as shewn in Figure 17, the weight of the stay-
bar e being relied upon to cause the engagement.
In the arrangement shewn in Figures 18 and 19 the stay-bar is retained by
means of a weighted arm s hinged at t to the guide fand provided with a tongue
or tooth dropping into holes & in the top of the stay-bar c. The disengagement
is caused by lifting the bar when the left hand top edge thereof will raise the arm »
and thereby move the tooth out of the hole k.
The arrangement shewn in Figures 20 to 23 is the same as that last described
with the exception that the edge of the weighted arms drops into notches k made
in a rib along the top of the stay-bar e which is here shewn of a cylindrical
shape. The bracket g is shewn of a shape suitable for use with double casement
windows.
Or the stay-bar e may be made of a flat shape as shewn in Figures 24 and 25
with the notches in its top edge, the slot being shaped to correspond with
the bar.
In the arrangement illustrated in Figures 26 and 27 the stay-bar c is secured by
means of a tooth jon a vertically sliding block » working in the guide f, the said
block being formed with a slot w through which passes the hinged weighted arm s
which, when the free end of the bar hangs down, drops in front of the horizontal
portion, as shewn by the full lines in Figure 26, and presses the tooth j into the
hole in the top of the stay-bar. The raising of the said free end of the bar when
bout to adjust the window lifts the arm s, as shewn by the dotted lines in
Figure 26, and consequently moves the tooth out of engagement. The arm is
provided with a roller c which bears upon the top of the stay-bar and facilitates
its sliding movement.
It will be evident that a person can adjust my combined stay and fastener by
using only one hand which is a great advantage over ordinary stays and fasteners
which require the use of both hands to operate them.
In the drawings I have shewn several shapes of stay-rods which I have found
to be suitable for the purposes of my invention but I do not confine myself to
these shapes, as they can obviously be varied without in any way departing from
the principle of my invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. A combined stay and fastener for casement windows consisting essentially of
a stay-rod or bar secured to the window by a universal joint and adapted to slide
in a pivotted guide fixed to the window frame and having a tongue, rib, or its
equivalent engaging with notches, holes or the like in the stay-bar, substantially as
herein before described.
2. In a combined stay and fastener for casement windows of the construction
claimed in Claim 1, a stay-rod formed in several pieces or sections jointed together,
substantially as, and for the purpose hereinbefore described with reference to the
accompanying drawings.
3. In a combined stay and fastener for casement windows the use of a stay-rod
provided with a spherical end or ball working in a correspondingly shaped socket
fixed to the window, the said rod working through and being adapted to be secured
in a pivotted guide, substantially as hereinbefore described with reference to the
accompanying drawings.
4. The combination with a combined stay and fastener for casement windows

page_text: constructed according to Claim 1, of a spring or weight for keeping the tongue or
its equivalent in engagement with the stay-bar, substantially as hereinbefore
described.
5. The improved combined stays and fasteners for casement windows herein-
before described with reference respectively to Figures 1 to 4, Figures 8 to 12,
Figures 13 to 17, Figures 18 and 19, Figures 20 to 23 and Figures 26 and 27 of
the accompanying drawings.
