Improvements in Ventilating Factories, Spinning-rooms, Workshops,
and other places, and in Heating, Moistening, Cooling, and
Filtering Air for the same.
I, PHILIP PARSONS Norgrove Buildings Clark's Place Bishopsgate Street Within
London E.C. in the County of Middlesex Engineer 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 has for its object the triple purpose of ventilating, heating and
moistening the air in factories, spinning roonis, workshops and other places. In
carrying out my invention I employ a pneumatic conductor; such as a fan. At the
inlet of each of these exhaust fans I employ four galvanized iron, or some other thin
metallic tubes, placed in such a position that they face east, west, north and south
respectively, the opening of said tubes being "beil-mouthed," that is to say larger
at the opening than close up to the fan. These fans are placed near the top of the
room to be ventilated and suck in the vitiated air, forcing the same through the roof,
or through a wall to the outside of the building, by means of a tube connected to the
outlet of said fans.
(1
A steam pipe is now placed round the walls, at a convenient height, and at
intervals spiral coils" are arranged. An opening is made in the walls where these
spiral coils appear, to allow the ingress of fresh air; each hole has a sliding door
to regulate the supply of air, and at the entrance of each hole a fine metallic gauze
screen is securely fixed to prevent the entrance of dust &c.
Each of these coils is drilled and tapped and a very small steam cock inserted, which
when opened will allow steam to come into the room, for the purpose of moistening
the incoming air.
The action of the machinery may be described thus:-When a fan is exhausting
by one opening only as has hitherto always been the case a most pronounced current
of air is always felt the movement of air is entirely different when the same fan is
sucking from the four points of the compass.. The fan sucks out the air in its
immediate neighbourhood in the shape of a whirlwind, which extends in this circular
movement until it encompasses the influence of the fan..
The fresh air now enters to fill up this vacuum and being much heavier than the
atmosphere of the room would fall instantly and cause a draught, which by my
arrangement of the spiral coils is prevented. The air is heated immediately it enters
the room and thus approximating more to the temperature of the room mingles
with it.
The fresh air is moistened to any extent by the steam jet in the spiral coil. In
summer cold water may be passed through this steam pipe and spiral coils to cool the
incoming air.
In order to prevent the water of condensation accumulating and falling, I place
these spiral coils in boxes of perforated metal, perforated at the sides, ends and top,
the bottom being solid and having a drip pipe to carry off the water.

exhaust fan. D steam pipe. É bell mouthed galvanized iron tubes, facing east, west,
north and south, and all concentrating at the inlet of the fan. F galvanized iron
tube connected to outlet of fan and carried through roof or through a wall to the

H steam cock for the purpose of moistening the incoming air.
J spiral coil. P drip pipe to carry off the water of condensation.
The fan C sucks the vitiated air through E and sends same out of the room
through F. The room is now supplied with fresh air coming in through B, this is
heated by J by the steam carried along through D, and moistened by the steam issuing
from H, the water of condensation passing away through P.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. The combination of an exhaust fan and four metallic tubes facing east, west,
north and south respectively and all concentrating at the inlet of the fan with outlet
pipe hereinbefore described.
2. The combination of an exhaust fan and four metallic tubes facing east, west,
north and south respectively and all concentrating at the inlet of the fan with outlet
pipe, openings in the walls with sliding doors and metallic gauze screens, arranged in
the-imanner berein before-more-particularly described.
3. The combination of an exhaust fan and four metallic tubes facing, east, west,
north and south respectively and all concentrating at the inlet of the fan with outlet
pipe, openings in the walls with sliding doors and metallic gauze screens, spiral coils
in perforated bores having a solid bottom, a steam cock and drip pipe substantially as
described and arranged in a ventilating, heating, and moistening apparatus.
Dated this 18th day of December 1890.
