COMPLETE SPECIFICATION.
Improvements in Ventilating Rooms.
We, FRANK WHITTAKER, of Rochdale Road Saw Mills, Timber Merchant and
Builder, WILLIAM ROSE, of 69, Union Street West, Builder's Manager, and
HARRY ROSE, of 31, Mitchell Street, Joiner, all of Oldham, in the County of
Lancaster, 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 improvements in ventilating rooms and has for its
object to so form the windows and some of its adjacent parts that although the
window remains closed the rooms will be continuously and thoroughly ventilated.
And in order that our invention may be more fully understood we have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Figs. 1, 4 & 7 are outside views, Figs. 2, 5 & 8 vertical sections at the same
scale as the front views, and Figs. 3, 6 & 9 vertical sections at an enlarged scale
of our improvements as applied to a shop window, mill or work-shop window
and house window respectively or any of them to public buildings.
In carrying out our invention and referring to the figures generally the improve-
ments consist in the first place in providing between the top rail a of a window
and the window head or ceiling one or more wedge like openings c which
narrow from the inside to the outside, i.e in the direction of the current, and
are protected outside by a hood d, the said wedge like opening or openings serving
for the exit of the foul air and setting up an ejector like action, will accelerate
the same, whilst the said hood prevents the foul air being blown back or rain
blown into the room.
Our improvements consist in the second place in forming, in case of house
windows, one or more similar wedge like openings e in the outer portion of the
top rail al of the inner window, as shown in Figs. 7, 8 & 9, which serve for the
admittance of fresh air and narrow in the direction of the current, which is
accelerated by the injector like action of the same.
This wedge like opening or openings are formed in case of a shop window, by
preference, by bevelling off the top edge of the top rail a, as shown in Figs. 1, 2
& 3, or in case of a mill or work-shop window, by forming the same in the window
head, as shown in Figs. 4, 5 & 6, or in case of a house window by bevelling off
the edge of the top rail of the upper sash, as shown in Figs. 7, 8 & 9.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1st. Providing between the top rail of a window and the window head or ceiling
or forming in the window head itself one or more wedge like openings c adapted
for the exit of foul air, all substantially as set forth.
2nd. In combination with the wedge shaped opening or openings specified in

page_text: the preceding claim, a hood & formed in front of the narrow end or ends thereof,
all substantially as set forth.
3rd. In house windows in combination with the foul air exit opening or
openings and hood specified in the preceding claims, a wedge like opening or
openings formed in the top rail of the bottom window adapted to form an
inlet for fresh air, all substantially as hereinbefore set forth.
Dated this 9th day of May 1899.
