PROVISIONAL SPECIFICATION.
Improvements in Windows and Window Ventilators.
ARTHUR ERNEST WYNN, The Cairn, Harrogate, Hydropathic Manager, do
hereby declare the nature of this invention to be as follows:-
--
My invention consists of a combination of window and ventilator, so constructed,
that without any apparent difference in the window frame it contains a ventilator,
which lets abundance of fresh air into the room without causing a draft; and if
thought advisable the air can be filtered so as to come into the room perfectly
pure.
The window is also so constructed that air will only enter at the ventilator and
not between the frames of the window.
A window constructed in accordance with my invention has the top and one or
both of the side frames formed hollow. The lower part of the hollow side of the
frame communicates with the exterior of the building by an opening or short
passage, preferably covered with a wire gauze; whilst the top hollow cross part of
the frame communicates by means of a long slit with the interior of the room.
This slit can be closed or opened to any desired extent by means of a curved hinged
bar, which is normally kept closed by weight and lever, or a spring. The vertical
hollow passage in the side of the window frame is divided vertically by a light.
This
rectangular frame carrying a canvas, muslin, gauze, or the like filter.
rectangular frame fits in slides suitably formed, so that it can be inserted in place
or withdrawn (on the inner side of the window frame) for cleaning purposes. It
will be understood that the vertical passage, on the one side of the canvass frame,
communicates only with the top horizontal part of the window frame; and on the
other side only with the before mentioned passage or opening to the exterior of the
building.
In order to keep those parts of the window, which are opened and closed, (the
pane or sash bars and frames), perfectly water and draught proof, I make them to
close upon each other with curved grooved or rabbited joints.
I prefer also to form my windows with three panes viz. :- -a fixed top cross or
horizontal pane, and two vertical panes, one of which is hinged vertically at the
side. To render the bottom joint thoroughly water proof, I place a vertical bead
on the outside in front of the joint, and over the bead a cover piece with a narrow
groove on the underside.

Improvements in Windows and Window Ventilators.
I ARTHUR ERNEST WYNN of The Cairn, Harrogate in the County of York
Hydropathic Establishment Manager do bereby 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 consists of a combination of window and ventilator, so constructed,
that without any apparent difference in the window frame it contains a ventilator
..

page_text: which permits abundance of fresh air to enter the room without causing a draught,.
and if desired the air can be filtered so as to come into the room perfectly free from
dust. The window also is so constructed, that air can only enter at the ventilator,
and not between the frames of the window.
This
A window constructed in accordance with my invention has the top and one (or
both) of the side frames formed hollow. The lower part of the hollow side of the
frame communicates with the exterior of the building, by an opening or short
passage preferably covered with wire gauze whilst the top hollow cross part of the
frame communicates by means of a long slit with the interior of the room.
slit can be closed or opened to any desired extent by means of a curved hinged bar,
which when no ventilation is desired is kept closed by means of a lever and weight
or a spring. The vertical hollow passage in the side of the window frame is
divided vertically by a light rectangular frame carrying a canvas; muslin, gauze or
the like filter. This rectangular frame fits in slides suitably formed, so that it
can be inserted in place or withdrawn (on the inner side of the frame) for cleaning
purposes. It will be understood that the vertical passage on the one side of the
frame communicates only with the top hollow horizontal part of the window frame,
and on the other only with the before mentioned passage or opening to the exterior
of the building.
In order to keep those parts of the window, which are opened and closed (the
pane or sash bars or frames), perfectly water and draught proof, I make them to
close up on each other with curved, grooved or rabbited joints.
I prefer also to form my windows with three panes viz. :-a fixed top cross (or
horizontal) pane, and two vertical panes, one of which is hinged vertically at the
side. To render the bottom joint thoroughly waterproof place a vertical bead on
the outside in front of the joint, and over the bead a cover piece with a narrow
groove on the underside.
And in order that my invention and the manner in which the same is to be
performed may be more readily and clearly understood I have annexed hereto the
accompanying drawings in which :-
Fig. 1 is a front elevation partly in section on line A B Fig. 3.
Fig. 2 is a vertical section on line C D Fig. 1.
Fig. 3 is a horizontal section on line E F Fig. 1.
Fig. 4 is a horizontal section on line G H Fig. 1, and
Fig. 5 is a plan looking on the top.
In all the figures the same reference letter refers to the same or similar parts.
a is the top horizontal passage formed in the top cross frame, and 66¹ the vertical
passage in the hollow side frame which communicates with the exterior by the
opening or short passage c. d is the slit by means of which the top passage a
communicates with the interior of the room. e is the curved hinged bar for closing
the slit d, and which is drawn so as to close the slit by the spring f
The bar e is
pulled and kept open by means of a cord attached to the same, the opposite end of
the cord being attached to a pin, hook or other equivalent fixed in the side of the
window. g is the light rectangular frame carrying the canvas, gauze, muslin or
other filter, and which fits in the slides h, so that the frame can be inserted or with-
drawn from the interior of the room for cleaning purposes. The frame g as will
be evident divides the vertical passage b¹ into two portions, 6 and 6 respectively,
of which 6 communicates with the passage a, and with the passage c.
The construction of the bottom joint is shewn in
on the outside attached to the inclined slope of the
the cover piece attached to the bottom window bar
groove m on the underside.

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 :-
1º A window frame having the top and one (or both) of the sides hollow, the

page_text: lower part of the latter communicating with the exterior of the building, and the
top of the frame having an opening communicating with the interior of the room,
such opening being capable of being closed and opened more or less, all substan-
tially as and for the purposes herein set forth.
20 In combination with the subject matter of Claim 1°, the dividing frame
fitted with a canvas, gauze, muslin or other filter substantially as herein set
forth.
3° The combined window frame and ventilator substantially as herein set forth
and illustrated in the accompanying drawings.
4° In window frame ventilators the arrangement of the slit d and curved binged
bar e substantially as herein set forth or illustrated.
