I, ELIZABETH YOUNG, of 9, Kelvingrove Street, in the County of the City of
Glasgow, North Britain, 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:-
My invention has for its object to allow windows to be open at top or bottom.
for ventilation and at the same time exclude dust, soot, and other impurities from
entering the rooms.
In order that my invention may be properly understood and readily carried
into effect, I have hereunto appended one sheet of drawing of which
Figure 1 is a front elevation showing my improvements and
Figure 2 is an end view of the same.
The screen consists of a frame A of any convenient size made of wood, or
other material, the centre being filled in with wire cloth B or any other suitable
substance. The ends of the frame A are provided with movable pieces C, having
a small rod or pin H connected to it which works in the slot E so that the
pieces can slide out and in, and they are retained in any desired fixed position
by meaus of the thumb-screw D. The frame, it will thus be observed, can be
adjusted to suit any size of window. To prevent any dirt getting in through
the slot E when the movable piece C has been drawn out, I provide a lip or
plate F, which is screwed or otherwise fixed to the under side of the sliding
pieces C.
When the window is raised at the bottom this screen rests against the window

page_text: sashes and while admitting fresh air through the wire gauze yet, from the fineness
of the mesh, prevents a draught such as would be occasioned with the ordinary
open window, and further no soot or other foreign matter in the air is allowed
to-pass-through-the-gauze, but rests on the outside of it so that it can be readily
wiped off.
To enable the screen to have a firm grip on the window sash and to prevent
rain getting in I provide a piece of india-rubber tubing G which I fix to the
ends of the frame.
Having now particularly described the nature of my said invention and in what
manner the same is to be performed I declare that what I claim is :-
The dust screen for windows constructed substantially as and for the purposes
herein before described and illustrated on the accompanying sheet of drawings.
Dated this 8th day of January 1897.
