page_text: WILLIAM PAUL, Writer & Grainer, 191 Shakespeare Road Herne Hill in the
County of Surrey, do hereby declare the nature of my invention for "A WINDOW
APPLIANCE FOR ROOM VENTILATION" to be as follows:-
Is designed for the purpose of admitting a current of fresh air into sleeping or
other apartments without the danger of draught. It is intended to be placed on.
the lower part of a window frame and its ends are made to extend, so that it can
be used for any ordinary sized window. The lower-sash being then pulled down
upon it, permits of the fresh air passing upward into a room between the meeting
bars of the sashes.
My invention consists of a slide about the size of the rail of the lower sash of
an ordinary window and slides by means of a slot cut in the inner side of one half
and pins in the other, admitting of an extension according to the width of a
window.
When not required.it can be removed and closed to half its extended length.
The top of the slide is fitted with India-rubber draught preventer.
-
To prevent the sash from being lifted up from the outside a pin is attached to
the ventilator which when passed through the sides of the frames securely fastens
them.
The novelties for which I make claim are. 1st Its sliding character; it being
readily fitted to any window and easily removed without disturbing any part of
the frame.

page_text: WILLIAM PAUL, Writer and Grainer 191 Shakespeare Road Herne Hill in the
County of Surrey, do hereby declare the nature of my invention for A WINDOW-
APPLIANCE FOR ROOM VENTILATION and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
Is design'd for admitting a current of fresh air, into sleeping and other apart-
ments, without the danger of draught.
It is intended to be placed on the lower part of a window frame and its ends are
made to extend so that it can be used for any ordinary sized window; the lower
sash being then pulled down upon it permits of the fresh air passing upward into
a room between the meeting bars of the sashes.
My invention consists of a slide about the size of the rail of the lower sash of
an ordinary window and slides by means of a slot cut in the inner side admitting
of an extension according to the width of a window.
When not required it can be taken out and closed to nearly half its extended
length, the top being fitted with India Rubber Draught Preventer.
To prevent the sash from being lifted up from the outside a pin is attached to
the ventilator, which, when passed through the sides of the stiles of the sashes,
securely fastens them.
Having stated the nature of my invention I shall now proceed to describe the
details of the drawings representing the same.
Fig. 1. represents the appliance extended and in use. A. shews the slot in the
inner side by which the appliance slides. B. B. the pins in the inner side of the

Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is

removed without disturbing any part of the window frame.
