Improvements in and relating to Humidifiers or Air Moistening
Apparatus.
I, ARTHUR LYNE JONES, of 229, Catoma Street, Montgomery, in the County of
Montgomery, and the State of Alabama, of the United States of America, Manu-
facturer, 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 humidifiers or air moistening apparatus for general
use, but particularly in textile manufactories, and consists primarily of a cylinder
suspended from a suitable support having a lower body enclosing a water tank
and an air pipe with feeding branches extending therefrom in radial lines and
co-acting with water feeding pipes to produce a spray which is driven out-
wardly into the surrounding air from a point between the cylinder and body,
the air being under pressure and the water tank automatically and continuously
replenished during the time the devices are permitted to operate.
The invention further consists of the details of construction and arrangement
of the several parts which will be hereinafter more fully described and claimed.
The object of the invention is to humidify an apartment by thoroughly per-
meating the atmosphere thereof with moisture, and particularly in textile manu-
factories for the purpose of carrying off the electricity with which the fibres of
the yarns become charged from friction of belts, etc.; to moisten textile fabrics
and provide for easy manipulation of the same, which in a dry atmosphere
become harsh and brittle and offer a materially increased resistance to the various
processes of manufacture; to cool and purify the atmosphere of a factory room
where light particles or lint are liable to remain suspended or float to the
detriment of the workmen and injury of the machinery, and to increase the
specific gravity of such particles or lint sufficiently to cause a precipitation there-
of and a consequent purification of the atmosphere.
In the accompanying drawings:-
Fig. 1 is an elevation of a humidifier embodying the invention.
Fig. 2 is a similar view broken away to show the construction.
Fig. 3 is an elevation on an enlarged scale of the air and water pipes and
their arrangement for spraying.
Fig. 4 is a section of the parts shown by Fig. 3.
Referring to the drawings, wherein similar numerals are utilized to indicate
corresponding parts in the several views, the numeral 1 designates a cylinder
open at top and bottom and having a lower flared flange 2. Secured to the said
cylinder is a strap metal or analogous frame 3 which is projected above the top
and designed to be attached to a ceiling or other support by means of suitable
fastening devices. The cylinder is preferably secured to the frame by means
of bolts 3 passed therethrough and through slots in the side bars of the frame,
so that it may be slid up on said frame when it is desired to have access to the
nozzles or water tank, thereinafter described. The frame 3 extends through
and below the flange 2 of the cylinder, and is connected to a lower body 4 con-

page_text: fining therein a water tank 5. The bottom of the body 4 is necessarily closed,
and the upper portion is provided with a flaring flange 6 of greater diameter than
and reversely arranged to the adjacent flange 2 of the cylinder. A suitable space
is left between the edges of the two flanges to form a free exit for the spray,
and over the water tank within said body and below the flange 6, a conical cover 7
is secured to prevent the deposit of lint or other particles in the water. This
cover is preferably composed of two like sections or pieces which fit together
and interlock, so that it may be easily and quickly applied and removed.
Extending centrally downward through the cylinder, cover 7 and into the water
tank 5 is an air supply pipe 8 which is closed at its lower end and secured to the
bottom of the tank and may be fastened at its upper end to the frame 3, and also
united to the cylinder by braces 9 if desired. During the operation of the device,
air is forced into this pipe continuously from an air pump, and when it is desired
to have the operation of spraying cease, the air is shut off by any suitable means
or the air pump can be stopped. A feed water pipe 10 runs parallel with the air
pipe and enters the water tank 5, and connects with a valve of preferred form
controlled by a float 11 to cause the said tank to be always supplied with water,
or to replenish it after a certain quantity has been withdrawn therefrom. The
upper ends of the air pipe and feed water pipe may be extended beyond the
frame 3 and fixed to the ceiling, wall, or other support, or secured directly to
said frame and provided, as shown, with nipples or couplings for the attachment
thereto of hose or metallic pipes leading from the sources of supply of the com-
pressed air and water.
The air pipe might be reversed and extend upwardly through the water tank,
body, cover and cylinder instead of downwardly through the cylinder into the
body and tank, which would be an obvious change within the confines of the
invention.
Rising parallel with and surrounding the air pipe 8 are a plurality of water
delivery pipes 12 which have their lower ends submerged and near the bottom
of the water tank. Just above the conical cover 7, these pipes 12 are gradually
bent upward in oblique angles in the form of radial feed branches 13 and ter-
minate in upturned contracted nozzles 14. From the air pipe S above the
branches 13, a similar number of small radial air feeding pipes 15 project
horizontally and terminate in contracted nozzles 16 which stand in line with and
touch the upturned nozzles 14 of the branches 13, and the air is forced directly
across the nozzles 14. This exhausts the air and sets up a suction
in the branches 13 and pipes 12, and the water is thereby drawn
upwardly from the tank 5, and comminuted and thrown out in the
form of spray or fine mist with a force proportionate to the pressure in the air
pipe 8. This operation also causes a circulation of air through the cylinder 1
with material advantage, and the flange 6 projects outwardly far enough to catch
all the heavier particles of moisture which fall, and cause such collected moisture
to flow back into the tank as the conical cover is of such dimension relatively
to the body 4 as to permit this, and yet serve to prevent the lint or particles in
the surrounding atmosphere from falling into the tank.
The ends of the spraying devices, including the water delivery and air pipes,
are about in line with the upper edge of the lower flange G so that the water of
condensation may be more quickly taken up by said flange, and the spray be more
nearly directed in a substantially straight line through the space between both
flanges. The upper flange 2 in its reverse position to the flange 6 prevents the
spray from being thrown upwardly, and the greater diametrical extent of said
flange also facilitates the collection of the water of condensation.
The clouds of spray or mist given off, are quickly absorbed by the atmosphere
or air, and the particles or lint becoming saturated and too heavy to remain in
suspension fall to the floor or elsewhere with beneficial results.
The number of the pipes 12 and 15 may be increased or diminished, and the
general proportions of the entire device may be varied at will. Also more than

page_text: one of the devices may be mounted in a single apartment and will be supplied
with air and water from the same line of feeding pipes.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. In a humidifier of the character set forth, the combination of a cylinder
having a downwardly flaring surrounding flange, a lower body adjacent said
cylinder having an automatically fed water tank therein and an upwardly flaring
surrounding flange spaced apart from the flange on the cylinder and of greater
diameter than said latter flange, a conical cover in the body above the water
tank and of slightly less base diameter than the said body to provide a space for
the return to the tank of the water of condensation, water pipes having outlet
ends located immediately above the said cover, and air pipes having free ends
meeting the outlet ends of said water pipes to create a suction in the latter and
force the water out between the flanges of the cylinder and body.
2. In a humidifier of the character set forth, the combination of a cylinder
open at top and bottom and having a lower flaring flange, a body suspended from
said cylinder and confining a water tank therein and also provided with an upper
flaring flange of greater diameter than and spaced apart from the flange on the
cylinder, a conical cover in the body above the water tank, a feed water pipe
entering the tank and having an automatic valve, an air pipe passing up through
the body, cover and a portion of the cylinder and having a closed upper end,
water delivery pipes surrounding the air pipe and having their lower ends pro-
jected into the tank and their upper portions above the cover formed with
branches terminating in nozzles, and air feeding pipes extending downwardly
from the air pipe and having nozzles touching and coacting with the nozzles
of said delivery pipes.
3. In a humidifier of the character set forth, the combination of a cylinder
having a lower flange, a body supported below the same and having a water tank
therein and an upper flange, a conical cover in the body above the water tank,
water pipes having outlet ends located immediately above the said cover, and air
pipes having free ends meeting the outlet ends of said water pipes to create a
suction in the latter and force the water out between the flanges of the cylinder
and body.
