PROVISIONAL SPECIFICATION.
Improvements in Reversible Sliding Windows.
I WILLIAM YOULTEN of 159 Victoria Street Westminster Architect, do
hereby declare the nature of this invention to be as follows:-
In order to provide a simple and efficient weather check between the faces of
cord and glass stiles in reversible sliding windows and the like I form in each
abutting face of the said stiles any suitable number of spherical or angular
corrugations so placed in juxtaposition that when the sash is in its ordinary
vertical position the convex curves of the corrugations formed on the abutting
faces of the cord stiles enter the concave curves of the corrugations formed on the
abutting faces of the glass stiles and vice versa.
By the use of any suitable means of drawing the two stiles together such as may
be effected by the insertion of thumb screws through the glass stiles the two stiles
may be drawn tightly together and an efficient draught proof joint be thereby
secured. To prevent the passage of water a throat groove can be run down one or
both of the abutting faces of the said stiles.

COMPLETE SPECIFICATION.
Improvements in Reversible Sliding Windows.
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 :-
According to this invention, in order to provide a simple and efficient weather
check, between the faces of the cord and glass stiles, in reversible sliding windows
and the like, I form in each abutting face of the said stiles any suitable number of
rounded, or angular corrugations or waves, so placed in juxtaposition that when
the sash is in its ordinary or vertical position the convex curves of the corrugations
formed on the abutting faces of the cord stiles enter the concave curves of the
corrugations formed on the abutting faces of the glass stiles and vice versa.
By the use of any suitable means of drawing the two stiles together, such as may
be effected by the insertion of thumb-screws through the glass stiles, the two stiles
may be drawn tightly together, and an efficient draught-proof joint be thereby
secured. To prevent the passage of water, a throat groove can be run down one
or both of the abutting faces of said stiles.
And in order that my said invention may be better understood I will proceed to
describe the same with reference to the drawing accompanying this Specification in
which Fig. 1 is an elevation of a portion of a pivotted window sash and Fig. 2 is a
plan.
The same letters denote the same parts in both the views.
The window sash shewn in Fig. 1 is divided into two parts forming the cord and
sash stiles and respectively in elevation at Fio 1 and ulan at Eir 2. The

page_text: abutting surface c of the part a and the abutting surface d of the part 6 are formed
with any suitable number of rounded or angular corrugations o or waves, as shewn
in plan at Figs. 2 and 3, the latter fig. shewing these drawn full size for sake of
clearness. These corrugations o are so arranged that when the sash is in its
ordinary vertical position, the convexities of the corrugations formed on the
surface d enter the concavities of those formed on the surface c and vice versa.
-e shews the pivot of sash, p shews the throat groove to prevent the passage of
water.
By providing a pivot e of suitable length and leaving a play equal to the
horizontal width of the corrugations between the sash and the sash frame, upon
releasing the screws or other stile fastener the sash can be revolved.
It will be seen that when the parts a and b are drawn tightly together by means
of the thumb screws n n or other fastener, an efficient draught-proof joint is
- obtained, owing to the surfaces c and d being corrugated as before described.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
-claim is :-
1. The improvements in reversible sliding windows, substantially as and for the
purpose set forth.
2. In reversible sliding windows, the abutting surfaces of the sash stiles having
corrugations or the like thereon so that when the stiles are drawn together when
in their vertical position an efficient draught proof joint is formed between the
abutting surfaces.
