Moistening, Heating, and Ventilating Factories.
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 to be as follows :-
This invention has for its object the triple purpose of moistening, heating and
ventilating factories in accordance with the "Cotton Cloth Factories Act 1889."
In carrying out my invention I employ a Pneumatic Conductor, such as a Fan,
coupled up to an engine or driven by a belt whichever may be found the more
convenient. A Heater placed in close proximity to the Fan and connected together
by galvanized iron, or, some other thin metallic tube.
Similar metallic tubes are also connected to the inlet of the Fan from the top of the
outside of the factory, or, some other convenient place, for the purpose of securing a
supply of pure air; and from the outlet of the Fan they are carried along the ceiling
of the Factory arranged in suitable positions, with slots, for the purpose of
allowing the air to enter the room, and properly arranged striking plates inside of said
tubes, at the slots, so as to allow the same volume of air to flow from each slot,
readings being taken by the Anemometer for this purpose, and thus distribute the air
equally all over the room without draught.
The Heater is charged with steam, live or exhaust, preferably the exhaust from
engine attached. The air is drawn from the highest convenient position to get pure
air, and sent through the Heater, where it is heated to the desired temperature; upon
leaving the Heater it is met by a very fine spray of pure cold water which it absorbs,
and passes on through the metallic tubes along the ceiling of the room and is thus
distributed through the room. The slight impulse of the heated air carries it to the
floor line, whence by the natural circulation set up by the cold outer walls, and the
pressure of following heated air currents, it takes a course toward the centre of the
building, and finally rises toward the roof. The air will generally find ready enough
exit from windows and doors, and through various crevices.
By this means the air is distributed through the building, without draught, and
moistened in accordance with the Act of Parliament.
A Hygrometer, composed of a dry and wet bulb, must be placed about three feet from
the wall, and one in the centre of the room. The hygrometers must not touch the
walls or the readings will be effected.
The wet bulb of the hygrometer can be regulated by turning the supply of cold
water on or off at the nozzle, or entrance of the spray, and the temperature of the air,
or dry bulb, by steam passing through the Heater.

Moistening, Heating and Ventilating Factories.
PHILIP PARSONS Norgrove Buildings Clarke's Place Bishopsgate Street Within
London, EC. 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:—
The invention has for its object the triple purpose of moistening, heating and
ventilating factories in accordance with the Cotton Cloth Factories Act 1889. The
general construction of the apparatus is such that a current of air from the external
atmosphere is drawn through a Heater, raised to a high temperature and then passed

page_text: through various mist jets of water in order to absorb a large quantity of moisture
whilst at the higher temperature, and then passed through a Condenser so that when
distributed through the room shall contain 88 per cent. relative humidity at a
temperature of 60° to 70°.
In carrying out my invention I employ an Air tube A, a Heater B, a Fan C,
an Engine D, a moistening Chamber F, and a Condenser H, G being the moistening
sprays. I main trunk pipe containing air for distribution. J boxes in main trunk
with sliding doors on either side to regulate the distribution of air. K. sliding doors.
L branch pipes, diminishing in size from trunk pipe to end. M triplet Bends to
distribute the remains of the air more equally. N slots, with striking plates arranged
in sizes so as to distribute the air without draught, and cause the temperature to be the
same all over the room.
The air is drawn from the outside atmosphere by C through A into B where it is
heated to a high degree in winter time and cooled in summer, steam being used at the
former and cold water at the latter period of the year. The air is then passed by C
through F and H in the manner indicated by the arrows, Fig. 3. The Chamber may
be made in any form, but I prefer to make it in a rectangular shape, the square of
each division being equal to the opening of the Fan, and the open spaces for the air to
pass from one division to the other being of the same size. In each of these divisions I
place a mist jet of water and one of steam or air. These mist jets may be made in
any desired form or shape. I prefer either a spray distributor in which the spray is
distributed by steam or air; a plain piece of copper tube perforated from end to end
and placed vertically in the divisions; a coil of the same metal tube placed at or near
the bottom of said divisions; or a copper rose, like that of a watering can, placed in
the same position, so that the water may issue from the bottom to the top of said
divisions. The jets of steam should be very small and very small quantities used.
The air now being prepared by passing through the Condenser, the number and
height of the divisions being made to suit the size of the room, is passed along I
distributed by J by the opening and closing of K through L and striking up against N
is equally distributed throughout the room without draught. M serves to distribute
the remains of the air more equally than coming out of one straight tube.
Fig. 1. is a plan view of the whole arrangement.
Fig. 2. is a side view of the same.
Fig. 3. is a longitudinal section of air moistening Chamber and Condenser.
For buildings of more than one floor the arrangement of piping for each floor is
substantially a fac simile. One set of machines being made equal to the installation,
and the main trunk pipe being large enough to supply all the floors.
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 a Fan, Heater, Air moistening Chamber, Condenser and
fittings herein before described.
2. The combination of Air inlet, Fan, Heater, Air moistening Chamber, Condenser
and fittings, Air distributing pipes with boxes and sliding doors, arranged in the
manner hereinbefore more particularly described.
3. The combination of air inlet, Fan, Heater, Engine, Air moistening Chamber,
Condenser and fittings, Air distributing pipes with boxes and sliding doors, and Slots
with striking plates, substantially as described and arranged in a moistening, heating
and ventilating apparatus.
