I, WILLIAM YOULTEN, of 159, Victoria Street, Westminster, in the County of
London, Architect, do hereby declare the nature of this invention to be as
follows:
In order to get rid of the "straight joint" about the pivots of the usual centre
hung window, and consequent admission of draught and wet, I provide on either
the outside or inside face (or on both faces if preferred) a suitably shaped plate,
one angle of which is affixed to the stile of the sash: another projects in segmental
form at right angles from the angle last described for fixing, and the periphery
of the segment has a flange which (when the sash is in position in its frame) is at rest
in a circular groove formed in the wood frame for the reception of the above mentioned
flange, or if preferred, instead of the groove in the wood frame mentioned, a suitably
shaped and grooved metal plate is affixed to the frame. When at rest the parts
of the flanged segments below the centre of the circle about which a centre hung
sash is partly rotated, receive the weight of the sash and the usual pivots are
rendered unnecessary, although if desired they can be provided.

I, WILLIAM YOULTEN, of 159, Victoria Street, Westminster, in the County of
London, Architect, 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:-
In order to get rid of the "straight joint" about the pivots of the usual centre
hung window, and consequent admission of draught and wet, I provide on either
the outside or inside face (or both if preferred) a suitably shaped plate, one
flange or bend of which is affixed to the stile of the sash another bend projects
in segmental form at right angles from the portion last described for fixing,
and the periphery of the segment has a flange, which (when the sash
is in its frame) is at rest in a circular groove in the wood frame,
for the reception of the above mentioned flange, or if preferred instead of the

to the frame. When at rest, the parts of the flanged segments below the centre of
the circle, about which a centre hung sash is partly rotated, receive the weight of
the sash and the usual pivots are rendered unnecessary although if desired they
can be provided.
And in order that my said invention may be better understood I will now
proceed to describe the same with reference to the drawing accompanying this
specification.
DESCRIPTION OF THE DRAWING.
Fig. 1 shews plan of a fanlight stile with my improved centre applied thereto.
Figs. 2 to 6 are details hereafter referred to.
a shews fanlight stile, having plates and b attached. one on each side. The
plate is shewn in perspective at Fig. 2 and in elevation at Fig. 3; and the
plate is shewn in perspective at Fig. 4 and in elevation at Fig. 5. Each of
these plates bb' is so formed that when it is attached to the salsh stile a by means
of the portion or c¹, another face d or d¹ of the said plate, projects from the
sash stile at right angles. The part. d or d¹ (which is of segmental shape). is
provided with a flange e or e¹, so that when the sash is in position in its frame
(as shewn at Fig. 1), this flange e or el rests in a circular groove f in a metal
plate gaffixed to the frame. This plate y is shewn at Fig. 6 in elevation.
The plate b is shewn provided with a spring catch h. Instead of having two
plates 6 and 61, one plate may be used extending across the thickness of the sash,
as shewn by the dotted line at i Fig. 1.
Centres constructed as above described, completely protect the joint from wind
and wet.
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:-
Centres of centre hung windows, constructed substantially as and-for. the
purpose set forth.
