PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Humidifying the Air of Factories
and other places.
I, WILLIAM TATTERSALL, of Southfield Square, Bradford, in the County of
York, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in apparatus for humidifying or moistening
the air of factories, mills and other places.
For this purpose I employ a number of water vessels preferably suspended from
the roof at the same level and fed by pipes connecting them to a common cistern
supplied with water by a ball cock. The said vessels are supplied with saucer
shaped covers which are perforated so as to drain into the vessels below. Air pipes
supplied with air under pressure and terminating in a nozzle or nozzles or con-
tracted orifices are fitted above the said covers. One or more spray pipes are
fitted in each water vessel and provided with nozzles or contracted orifices which
approximately meet said air pipes at a suitable angle. Or the air pipes may be
fitted inside the spray pipes or vice versa. The said air pipes are preferably fed
with fresh air which may be heated or cooled according to the temperature required.
Between the spray pipes and the said covers I introduce what I hereinafter term
a pulverising disc preferably adjustable in relation to the spray pipes which may
have flat, curved, corrugated or other suitably formed faces adjacent to said
pipes.
In operation the air rushing from the air pipes draws the water from the cistern
through the spray pipes dispersing it in the form of spray in a similar manner to an
ordinary spray producer but such spray striking or impinging against said
pulverising disc is completely pulverised and thrown off such disc in a most
finely divided state so that it is carried away by the air without condensing in
drops.
In the above described arrangement the air pipes are arranged with the nozzles
downwards but it is obvious that with slight modification the apparatus may be
constructed so that the nozzles of the air pipes point upwards or at any convenient
angle.

Improvements in Apparatus for Humidifying the Air of Factories
and other places.
I, WILLIAM TATTERSALL, of Arden Terrace, Plantation Street, Accrington,
in the County of Lancaster, Engineer, do hereby declare the nature of this inven-
tion 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 apparatus for humidifying or moistening
the air of factories, mills and other places.
For this purpose I employ a number of water vessels preferably suspended from
the roof at the same level and fed by pipes connecting them to a common cistern
supplied with water by a ball cock or in any convenient manner. The said vessels
are supplied with saucer shaped perforated covers or with saucer shaped flanges or
rims draining into the vessels below. Air pipes supplied with air under pressure

page_text: from any convenient source and terminating in a nozzle or nozzles or contracted
orifices are fitted above said vessels. One or more spray or water pipes are fitted
in each water vessel and provided with nozzles or contracted orifices which meet
said air pipes at the angle required for spray producing apparatus. Or the air
pipes may be fitted inside the spray pipes or such pipes may be arranged in any
approved manner for producing spray. The said air pipes are preferably fed with
fresh air which may be heated or cooled to the temperature required. Between
the spray pipes and said vessels I introduce what I hereinafter term a pulverising
disc or device which may be adjustable in relation to the spray pipes. Said discs
may have flat, curved, corrugated or other formed faces adjacent to said pipes but
for general purposes I find a flat disc gives satisfactory results.
In operation the air rushing from the air pipes draws the water from the cistern
through the spray pipes dispersing it in the form of spray in a similar manner to an
ordinary spray producer but such spray striking or impinging against said pulverising
discs is completely pulverised and thrown off such discs in a most finely divided
state so that it is carried away by the air without condensing in drops.
In the above described arrangement the air pipes are arranged with the nozzles
downwards but it is obvious that with slight modification the apparatus may be
constructed so that the nozzles of the air pipes point upwards or at any convenient
angle.
In order that my invention may be fully understood reference is to be had to the
accompanying sheet of drawings forming a part of this Specification in which similar
letters of reference indicate corresponding parts in each figure.
Figure 1, represents an elevation of a spray producing apparatus with my
pulverising device in position. Figure 2, is a vertical section of the same, and
Figure 3, is a plan view with the water pipe in section.
Figure 4, is a vertical section of a similar apparatus having four spraying
nozzles and pulverising discs, and Figure 5, is a plan view of the same.
The water vessel A fed from the water supply pipe B through the passage C is
suspended from the air pipe D by the spray pipe F and its continuation G. The
spray pipe F terminates in the water nozzle projecting at right angles beneath
the air nozzle & connected to the air pipe D and supplied with air under pressure
from the main air supply pipe H. The water pipe B is fed from a cistern supplied
with a ball cock or other convenient source in which the water is constantly
maintained at the level the water is required to stand in the water vessel A. A
valve I is provided to cut off the supply of air to stop the apparatus and a valve J
is also fitted to stop the supply of water in case the air is continued for ventilating
purposes when the spray is not required.
An arm K projecting from the spray pipe F carries the pulverising disc L which
is adjustable in relation to the pipes by the screw m and is fixed by the lock nut n.
In operation the rim N of the vessel catches the larger particles of spray that
might otherwise fall and they drain back into the vessel.
In the compound apparatus represented in Figures 4 and 5 the air pipe D and
water pipe Fare connected by the solid portion h. The pipe above / branches
out into four air nozzles d which meet the four water nozzles fand the pipe E com-
municates with the water vessel A by means of the passage or perforation C. The
pulverising discs L are carried by the arms K projecting from the pipe F and such
discs are inclined so as to throw the spray outwards.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I would have it understood
that I make no claim to the construction or arrangement of the spraying apparatus
simply and that I am aware jets of water have been previously directed against
solid bodies to break them up so that I make no claim thereto but what I do
claim is:
A pulverising disc or device arranged in combination with a spray producing
amaritus onerated by air under BOSSUTO in such 5
manner that the spray is

page_text: directed or impinges against said disc or device, substantially as herein shown and
described.
