Improvements in Ventilators for Houses, Factories, Churches, Ships,
or any other Class of Buildings.
ง
WILLIAM EDWARD ALDOUS, and FREDRIC DIGBY ALDOUS, both of
131 Upton Lane, Forest Gate, in the County of Essex, Ventilating Engineers,
do hereby declare the nature of this invention to be as follows:-
The apparatus or apparatuses consist of a motor driven by electricity, steam,
hydraulic pressure, gas, or any other driving power, as may be most conducive to
the working of the apparatus or apparatuses, together with a suitable fan &
accumulator; the fan & accumulator being attached, together, with various shafts
attached to the accumulator will form a perfect contact with any air either inside
or outside any building or ship.
An exhaust shaft is attached to the fan to receive the air drawn from the
various induct shafts connected to the accumulator, which will then be driven
through the exhaust shaft into the open air. The same means will be applied
to supply fresh air, by the fan revolving in an opposite direction so drawing the
air from the accumulator through a shaft, or shafts, attached to which will be
various & properly constructed nozzles to prevent draught, & to distribute the air
either in columns or sprays. Before this takes place it can be passed into a
chamber, & undergo a washing process, then into a disinfectant chamber before
reaching the destination for distribution.
A properly constructed separator to divide the air into columus, will be placed
in the main shaft.
Dated this 29th day of January 1895.

Improvements in Ventilators for Houses, Factories, Churches, Ships,
or any other Class of Buildings.
WILLIAM EDWARD ALDOUS and FREDRIC DIGBY ALDOUS, both of
131 Upton Lane Forest Gate in the County of Essex Ventilating Engineers,
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 :-
The object of our invention is to remove vitiated air, noxious gasses, smoke or
steam from houses, buildings, ships, or any other place where it exists.
The apparatus or apparatuses consists of a motor driven by electricity, steam,
hydraulic-pressure gas or any other driving power as may be most conducive to
the working of the apparatus or apparatuses consisting of a suitable fau or fans for
exhausting & supplying tresh air and accumulator attached to the fan case with
various shafts or tubes connected to the accumulator for the purpose of exhaust
and supply. The various shafts or tubes connected to the accumulator can be
carried to any part of a building or ship, which with collecting bonnets attached
Pin1

page_text: thereto will be the means of collecting and conveying the vitiated air down into
the accumulator (the shafts or tubes being attached to the accumulator, and the
accumulator to the fan case, the whole being hermetically sealed) will be driven
out through the exhaust shaft 1. The accumulator will be in two sections, in
order that the vitiated air in its exit through the accumulator shall not come in
contact with the fresh air passing at the same time from the main supply shaft a.
From this section of the accumulator, there is a shaft. h. (connecting the accumu-
lator and fan case) in which is placed a centre-hung disc or valve m. to regulate
the passing of the air; and the fresh air drawn into the accumulator is driven into
the vertical supply shafts a, in the same will be inserted a fine spray nozzle l.
in the chamber a for washing the air, also a reservoir e. for disinfectants. The
nozzle.. Fig. 1. for washing the air is a small metal spray nozzle perforated so as
to throw fine jets of water in every direction, a concentrating tube running through
same to near the face plate, leaving only sufficient space between the face plate
and inside crown to allow water to be forced through by the pressure behind it,
giving it a greater impetus, the nozzle being screwed onto a T piece, from the
supply pipe.
i
After the air has undergone the washing and disinfectant process in a large
column, it will enter the divided cone f, which consists of an obvert dish divided by
means of triangular plates, corresponding in number to that of the various shafts g.
Fig. 1. or any other corresponding number; attached thereto are various small
shafts g. to convey the fresh air as before described the divided cone will give cach
shaft an equal portion of air and no more; on each of the shafts or tubes will be
placed suitably constructed air nozzles k. placed at various distances apart to
discharge the air in fine sprays, or it can if necessary be discharged. in columns.
The nozzle k. Fig. 1. consists of a perforated rim, with a front and back plate, at
such a distance apart as to allow of only sufficient air passing to supply the
perforated rim; a concentrating nipple running through the back plate from
T'piece on shaft g. Fig. 1, to supply only sufficient air for distribution.
:
All the various shafts and tubes for exhaust and supply being in their proper
'positions hermetically sealed to the fan and accumulator, will form a perfect
contact between the inside and outside air as the case may require; thus forming
a combination and completing the object for which we declare..
And in order that our said invention, may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawing in which similar
letters of reference indicate corresponding parts.

Having thus described our improvements and means which w we adopt in carrying
the same into effect, we would have it understood that we do not confine ourselves
to the precise arrangements of parts shown and described, as the same may be
varied without departing from the particular character of our invention. For
instance, by crossing the belt, the exhaust will become the supply, and the supply
the exhaust, as may be necessary at times in certain places. But what we do
claim is:-
The nozzle for

3rd. Divided cone for splitting up large columns of air, and giving equal
proportions in small columns.
4th. Right and left hand fans worked in one case and by one pulley and belt.
5th. The accumulator separately and coupled to the fan frame. And
6th. The combination making one complete whole.
