PROVISIONAL SPECIFICATION.
Improvements in Sliding Sash Boxed Frames.
I WILLIAM YOULTEN of 34 New Bridge Street London, Architect do hereby
declare the nature of this invention to be as follows:-
:―
For the better ventilation of apartments lighted by sliding sash windows I
form an aperture or apertures in any convenient position in that portion of the
pulley stile or other portion of the ordinary boxed frame externally exposed when
both sashes are in their closed positions and another aperture or other apertures in
that portion of the pulley stile or other portion of the ordinary boxed frame
nternally exposed when the sashes are in their closed positions. Into the said
pertures I either omit every kind of framework or I provide suitable filtering
material or inlet regulators.
Dated this 15th day of October 1894
I WILLIAM YOULTEN of 159 Victoria Street Westminster (late of 34 New
Bridge Street) 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 :-
This invention relates to the better ventilation of apartments lighted by sliding
sash windows.
According to this invention I form an aperture or apertures in any convenient
position in that portion of the pulley stile or other portion of the ordinary boxed
frame externally exposed when both sashes are in their closed positions and
another aperture or other apertures in that portion of the pulley stile or other
portion of the ordinary boxed frame internally exposed when the sashes are in
their closed positions. Into the said apertures I may provide a framework or
suitable filtering material or inlet regulator. And in order that my said invention
may be better understood I will now proceed to describe the same with reference
to the accompanying sheet of drawings in which Fig. 1 is a plan of my
improvements fitted to a sliding sash boxed frame Figs. 2, 3, 4, and 5 shew details
hereinafter referred to.
a shews pulley stile; b shews sash; c ventilator inserted in an aperture c¹ in the
pulley stile a in such a position as to be externally exposed when both sashes are
in their closed positions; shews wire gauze inserted in another aperture d¹
in the pulley stile a which would be internally exposed when both sashes are in
their closed positions.
The ventilator c is shewn detached at Fig. 2 and a section of same is shewn at
Fig. 3. Fig. 4 shews wire gauze d, detached, fixed in a frame e by means of which
latter it is secured to pulley stile a. Fig. 5 shews section of gauze d and frame e.
The ventilator c (which is a hit and miss ventilator) is opened and closed by means
of the knob or handle attached to the rod g. At Fig. 1 shews the outside

page_text: lining and consequently the handle
is within the room or apartment. The
arrows in this view indicate the direction of the current of air when the ventilator o
is open and both sashes are in their closed positions.
The action is as follows :-
When the window is closed, the aperture in the pulley stile is exposed
externally and the other, d', internally so that when the ventilator c is opened a
current of air passes through the externally exposed aperture c¹ and the boxed
frame and then into the apartment through the internally exposed aperture d¹ and
the ventilator.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is: :-
1. The employment of apertures in the boxed frame of sliding sash windows in
such a position that when the window is closed one aperture shall be exposed to the
external atmosphere and the other to the internal atmosphere for the purpose
set forth.
2. The improvements in sliding sash boxed frames substantially as and for the
purpose set forth.
