PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Humidifying the Air of Factories
and other places.
I, WILLIAM TATTERSALL, of 90, Arden Terrace, Accrington in the County
of Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in the humidifying apparatus for which I
have obtained Letters Patent No. 4050 dated the 15th March 1890 and its object
is to increase the efficiency and capabilities of that apparatus.
As a result of repeated experiments I find that by enclosing the spray pulverizing
apparatus within a tube or close to the mouth of a tube or its equivalent a con-
siderable auxiliary current of air is induced therein and I find that this current
perfectly co-mingles with the current produced by the spraying apparatus and
besides thus carrying forward a proportionately larger quantity of water in
suspension the increased volume and velocity gives a much wider distribution. By
reducing the size of the pulverizing disc the increase in the volume of humidified
air is still greater.
To apply this improvement to my humidifier I preferably mount the spraying
apparatus with the pulverizing disc reduced in diameter within the mouth of a tube
inclined upwards to give wider distribution. And such tube is sufficiently long, to
enable it to collect all particles of water too large to remain in suspension and
drain them back into the basin. The other or delivery end of said tube may be
rounded and flattened in section so as to give a wider horizontal range, and
deflectors may be introduced to increase this effect. This tube is preferably, so
arranged that the air current may be drawn from outside if fresh air is required.
Two or more of these tubes may be arranged to radiate in opposite directions
from the same humidifying apparatus with a spray pulverizing arrangement. in
connection with each tube. Or the said tube may be fitted vertically with a
deflector at its delivery end to distribute the current around.
When two or more of said tubes are connected together stop taps are preferably
fitted to the water pipes of the spray pulverizing apparatus so that any one of such
tubes may be employed to introduce air without additional moisture.

Improvements in Apparatus for Humidifying the Air of Factories
and other places.
I, WILLIAM TATTERSALL, of 90, Arden Terrace, Accrington, in the County of
Lancaster, 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 relates to improvements in the humidifying apparatus for which I
have obtained Letters Patent No. 4050 dated the 15th March 1890 and its object
is to increase the efficiency and capabilities of that apparatus.
As a result of repeated experiments I find that by enclosing the spray pulverizing
apparatus within a tube or close to the mouth of a tube or its equivalent a con-
siderable auxiliary current of air is induced therein and I find that this current

suspension the increased volume and velocity gives a much wider distribution.
By reducing the size of the pulverizing disc the increase in the volume of
humidified air is still greater.
In the accompanying drawing.

་-་ Figure 1, represents a diametrical section of a single spray producing and
pulverizing apparatus fitted. with an induction tube in accordance with my
improvements.
Figure 2, is a plan view of the same, and
Figure 3, is a view of the end of the said tube.
Figure 4, is a diametrical section of a compound apparatus, and
F..
Figure 5, is a sectional plan of the same on the broken line a, b of the former
figure.
Similar letters of reference refer to similar parts.

In Figures 1 and 2 the branch pipe A of the air supply pipe B terminates in an
air nozzle C carrying the curved arm D which supports the spray or water pipe E
hanging down into the water vessel F and also the pulverizing disc G. The
induction tube H is also secured to the air pipe by the arms
radiating from such
pipe attached to the inner periphery of said tube as shown in Figure 3.
In operation the induced current is drawn in at K mingles with the pulverized
spray thrown off the disc G and passes out of the month L. To give a more
uniform distribution the tube H is preferably flattened in section towards the
mouth L and the under lip M is preferably turned up to induce the current to pass
out of the sides N of the mouth as well. The tube G is inclined to allow any
water which may be deposited therein to drain into the vessel F.
In the arrangement shown in Figures 4 and 5 four spray producers and four
pulverizing discs are mounted together and four induction tubes are provided
branching from the air shaft P closed below by the water vessel F and communi-
cating above with the fresh air.
It is obvious that a greater or less number of induction tubes and spray
pulverizing apparati may be arranged together in a similar manner. Or that a
vertical tube may be used.
In which case a conical or other suitable deflector is
fitted at its delivery end to distribute the current around.
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. In humidifying apparatus, the combination with.
pulverizing apparatus of an induction tube or tubes, substantially as herein shown
spray producing and·
and described.
2. The combination with a spray producing and pulverizing apparatus, of an
induction tube arranged to drain towards the spraying,apparatus, substantially as
herein shown and described.
3. The combination with a spray producing and pulverizing apparatus, of an
induction tube flattened in cross section towards the mouth, substantially as herein
shown and described...
4. The combination with a spray producing and pulverizing apparatus, of an-
induction tube or tubes communicating with an air shaft open to the fresh air only,
substantially as herein shown ana described.
