Improvements in or relating to Window Casements.
I WILLIAM YOULTEN of 159 Victoria Street London, S.W. Architect, do
hereby declare the nature of this invention to be as follows:-
Into the hanging and locking faces of a metal or wooden casement frame or
casement constructed to open either inwards or outwards (whether the said faces be
vertical or horizontal) I provide revolving or partly revolving rods of a circular or
corrugated section in such positions that freedom of action is afforded the casement
to move inwards or outwards by either a sufficient temporary depression or part
revolution of the rods as a consequence of the movement of the casement or in the
case of rods of a corrugated section by the revolution of the said corrugated rods
as a consequence of the movement of the casement because of the provision on the
opposite abutting faces of the casement of suitably formed corrugations. When
the casement is closed the interlocking of the rods with grooves or of some of the
cogs on the revolving rod provided in one abutting face with the corrugations
provided on the other abutting face prove to be an effectual means of excluding
draught and wet. By arranging for the stoppage of the said revolving corrugated
rod when the casement has been opened a sufficient distance or closed the usual
casement stay and casement fastener may be respectively dispensed with.

I WILLIAM YOULTEN of 159 Victoria Street S.W. Architect, do 'here
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 :-
Ι
a
Into the hanging and locking faces of a metal or wooden casement frame or
casement constructed to open either inwards or outwards (whether the said faces
be vertical or horizontal) I provide revolving or partly revolving rods of a circular
or corrugated section in such positions that freedom of action is afforded the
casement to move inwards or outwards by either a sufficient temporary depression
or part revolution of the rods as a consequence of the movement of the casement or
in the case of rods of a corrugated section by the revolution of the said corrugated
rods as a consequence of the movement of the casement because of the provision on
the opposite abutting faces of the casement of suitably formed corrugations. When
the casement is closed the interlocking of the rods with the grooves or of some
of the cogs on the revolving rod provided in one abutting face with the corrugation's
provided on the other abutting face will prove to be an effectual means of excluding
draught and wet.
And in order that my said invention may be better understood I will now

page_text: 1
proceed to describe the same with reference to the accompanying sheet of drawings
in which
Fig. 1 shews plan of hanging stiles of the casement and casement frame with my
improvements as applied to wooden casements..
Fig. 2 shews a plan of locking stiles of a casement and casement frame also with
my improvements as applied to wooden casements.
Fig. 3 shews plan of hanging stiles of the casement and casement frame having
my improvements adapted thereto as applied to metal casements.
Fig. 4 is a similar view to Fig. 3 but shewing position of casement when opened
outwards.
Fig. 5 shews position of metal casement representing the position of the casement
when opened inwards.
Fig. 6 shews plan of locking stiles of a metal casement and casement frame
representing the position of the casement when closed.
The same letters denote the same parts in all the views.
a shews the casement. The casement a is pivotted above and beneath the dotted
circle marked b. c shews a vertical revolving rod in hanging stile and c¹ that in
locking stile extending from the top to the bottom of the casement by preference.
d Figs. 1 and 2 shews a spring coming against the rod c; e shews friction plates;
fshews water throat; g shews groove to receive the rod c.
Although I have described and shewn the casement as pivotted at the top and
bottom so that it may open vertically I do not wish to confine myself to this as
I may have the pivots at the sides so that the casement may work horizontally
in which case the position of the revolving rods would be altered accordingly.
It will be seen on reference to Figs. 3, 4, 5, and 6 which shew my invention as
applied to metal casements that the vertical rods cc' are corrugated for the
purposes hereafter described.
The action is as follows with reference to Figs. 1 and 2.
When the casement is opened either inwards or outwards the vertical rod c
which extends from top to bottom of the casement as aforesaid is depressed by the
stile friction plates e into the position indicated by the dotted circle adjoining, so as
to allow of the casement being turned freely. The stile friction plates e only
extend up the stile from the bottom and down the stile from the top for a distance
of about two inches. In turning the casement again into its ordinary closed
position when the rod groove 9 reaches the revolving rod c the latter, actuated by
the rod springs d at once flies into position shewn on the drawing at Figs. 1 and 2
and thus effectually prevents draught.
C
The rod springs are of coppered steel coil, and are placed in brass tubes about
two feet distant from each other, thus in a window four feet six inches in height
only three of such springs are necessary..
The water throat prevents driving rain from passing.
With reference to Figs. 3, 4, 5, and 6. The casement is also pivotted above and
beneath the dotted circle marked on the drawing and when opened either inwards
or outwards the pivotted revolving corrugated rod c in the hanging stile actuated
by the adjacent corrugated face of the hanging stile marked I and 3 rotates and
thus permits the casement to turn freely and it then assumes the position shewn at
Fig. 4 of the drawings. In turning the casement into its ordinary closed position
again as shewn at Fig. 3 a reversal of the movement of the revolving corrugated
rod c is thereby caused and by the triple interlocking of the cogs marked 1 2 3 a
perfectly weather proof joint is obtained. Fig. 5 shews position of casement when
opened inwards.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
;
1. In casements opening inwards and outwards the employment of revolving rods
fitted to the hanging and locking stiles for the purposes set forth.

page_text: 2. In casements opening inwards and outwards the employment of revolving
corrugated rods fitted in the hanging and locking stiles in combination with the
corrugated face in the casement for the purposes set forth.
3. The improvements in casements substantially as and for the purposes set
forth.
