Improvements in or relating to Fastenings for Oasement Windows
and the like.
I, RICHARD JOSEPH STEPHENS, of 34 Belvoir Street, Leicester, Architect and
Surveyor, do hereby declare the nature of this invention to be as follows:-
11
My invention relates to fastenings for casement windows and the like and has for
its object the combination of a fastener, stay and opener.
To carry out my invention I may employ a casement stay or opener of ordinary
construction consisting of a bracket, capable of being secured to the casement and
having a projecting rod or bar loosely pivoted to a convenient part thereof. Another
bracket of suitable shape and construction may be fitted to the frame of the casement,
and the aforesaid rod or bar passed through the same and held in position by a
suitable thumb screw or the like.
My improvement consists in utilizing the bar before mentioned for the double
purpose of opening the casement and acting as a fastener when it is closed.
I preferably fix my improved combination fastener halfway up the casement instead
of on the bottom rail as is usually done, and I arrange it in such a manner that when
the casement is closed the projecting bar or rod will fall down in a vertical position
and form a secure fastener. This is effected by having a joint in the rod near the
point where it has passed through the bracket attached to the window frame.
I also provide a thumbscrew at or near the bottom end of the bar to prevent the
casement opening beyond the length of the bar, but such thumbscrew can be readily
removed to allow the casement to open to its full extent when necessary.
By securing my improved fastener near the centre of the casement frame the latter
is held more rigidly and is less subject to vibration by the wind or other causes.
Dated this 26th day of June 1888.

Improvements in or relating to Fastenings for Casement Windows
and the like.
I, RICHARD JOSEPH STEPHENS of 84 Belvoir Street, Leicester, Architect and
Surveyor, 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 fastenings for casement windows and the like and has for
its object the combination of a stay & fastener.
To carry out my invention I prefer to employ a casement stay or fastener of
ordinary construction, consisting essentially of a bracket, capable of being secured to
the casement and having a projecting rod or bar loosely pivotted to a convenient part
thereof, and also having another bracket which may be fixed to the frame of the
casement, and through which the aforesaid rod or bar is passed and held in position
by a stay-pin.
My improvement consists in utilizing the bar before mentioned for the double
purpose of a stay when the casement is partially opened, and as a fastener when it is
closed.
I preferably fix my improved fastener half way up the casement instead of on the
bottom rail as is usually done, and I arrange it in such a manner that when the
casement is closed the projecting bar or rod will fall down vertically and form a
secure fastener.
This is effected by having a joint in the rod or bar near the point where it has
passed through the bracket attached to the casement frame.
I also provide a thumbscrew at or near the bottom end of the bar or rod to prevent
the casement opening beyond the length of the said bar, but such thumbscrew may
be readily removed to allow the casement to open to its full extent when necessary.
In the accompanying drawings Figure 1 is a plan of a casement partly opened
having my iniproved fastoner applied thereto.
Figure 2 is an elevation of iny improved fastenor showing its position when the
casement is closed.
Figuro 3 is a plan of the fastener.
A is the bracket which is fixed to the casemont A' by means of sorows A'.
Working loosely on a pivot A' in the fork of the bracket A is one end of a rod or
bar B, the opposite end of which is provided with a thumbscrew or equivalent C to
enable the casement to be opened a distance equal to the longth of the rod or bar B
as shown in Figure 1, but the thumbscrew C can be removed altogether when it is
desired to open the casement to a greater extent or to its full limit.
The rod or har B is jointed at B3' so that when the casement is closed the said rod
or bar may hang at a right angle or depend vertically as shown in Figure 2 and thus
form a fastener to prevent the casement from being opened until the dopending part
is again raised in a horizontal line to form a continuation of the other or shorter part
& to pass through the boss D₁ of the adjustable stay D.

page_text: The end of the stay-pin D' of the adjustable stay D is kept in constant contact with
the rod or bar B so that it may the more readily lodge in the sockets B' in the
rod B.
To keep the end of the stay-pin D' thus in contact with the rod or bar B I provide
that the stem of the said pin may be provided with a spiral spring D³ or equivalent
enclosed by means of an adjustable thumbnut E.
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:
The construction or employment of a jointed casement stay or fastener substantially
such as described and illustrated in the accompanying drawing.
RICHARD JOSEPH STEPHENS.
