EDWARD JAMES GILLIS, Captain, late Public Works Department, India, of No. 22
Brighton Road, The Avenue, Southampton, Hants, do hereby declare the nature of
this invention to be as follows:-
The ventilator consists of perforated (plain) zine & tinted glass, and is fastened to
the upper part of the outside lining of the window frame and does not interfere with
the working of the sashes in any way. Ventilation can be regulated, as required, or
shut off completely. When ventilation is required the upper sash of window is to bo
lowered to within half an inch of bottom of ventilator, thus admitting fresh air, in
between the sashes and allowing foul air to escape. The invention can be fitted to any
sash window in a few minutes without injury to the window frames.
The accompanying drawings explains fully its construction.
E. J. GILLIS, CAPT.
I, EDWARD JAMES GILLIS, of 22, Brighton Road, The Avenue, Southampton,
in the County of Hants, Captain, late of the Public Works Department, India, do
hereby declare the nature of this invention, and in what manner the saine is
to be performed, to be particularly described and ascertained in and by the following
statement :-
This invention has reference to a ventilator suitable for use in the ventilating of
rooms or parts of buildings fitted with sliding window sashes.

page_text: A ventilator according to this invention comprises a box or case closed at the
bottom and at one side and open at the top, the remaining side being perforated or
reticulated. This box or case is provided with a longitudinal perforated or reticulated
division or guard arranged diagonally, and is designed to be secured to the upper part
of a window frame in such a manner as not to interfere with the lowering or raising
of the upper sash. The box or case may be of zinc or other metal, and is fixed with
its closed side (which may be glazed) outward.
In the accompanying drawing,
Fig. 1 is a vertical section, showing a ventilator according to my invention applied
to a window frame fitted with sliding sashes.
Fig. 2 is a front or outside view of part of the ventilator and window frame.
1 is a metal box or case with glazed outer or front side 2; perforated inner side 3;
closed bottom 4, and outlet 5 at top. 6 is a perforated division plate or guard arranged
diagonally as shown, and extending from end to end of the box or case.
7 is a
longitudinal ridge or projection with inclined surfaces to deflect wind. At each end
are ears or projections, one of which is shown at 8 in the drawings; 9 and 10 are
flanges respectively at the sides and top of the box or case, which extends across from
side to side of the window frame 11 to the upper part of which it is secured by
screws 12, passed through openings in the ears or projections 8, and flange 10 as
shown. 13 is the upper window sash arranged to slide in the frame 11 in the usual
manner; the lower sliding sash is not shown.
When it is required to ventilate the room or part of a building to which my improved
ventilator is applied the upper window sash 13 should be lowered, but so nevertheless
that its upper edge shall not be below the bottom of the box or case 1. Fresh air
will then be admitted to the room or compartment through the space there will then
be between the lower part of the upper sash and the upper part of the lower one, and
foul air will be able to escape through the ventilator as indicated by the arrows. By
adjusting the position of the upper sash, the ventilation may be regulated to requirement,
and by fully raising it the ventilation may be stopped.
Ventilators according to my invention may be applied in various situations as will
be readily understood.
Having now particularly described and ascertained the nature of the said invention,
and in what manner it is to be performed, I declare that what I claim is :-
1. A ventilator comprising a box or case 1 with perforated or reticulated division 6,
perforated or reticulated inlet side 3, and outlet 5, the arrangement being such that,
when applied as described, it will permit vitiated air to escape, and prevent draught,
as set forth.
2. The improved ventilator shown in and described with reference to the drawing
annexed.
