GEORGE W. nARcY, oF BOSTON, MASSACHUSETTS, s
VAPoRrzING APPARATUS;
Application filed March 31, 1923. Serial No. 629,208.
' This invention relates to vaporizing and humidifying apparatus and especially to that type of suchA apparatus that is particularly adapted for use in mills, mines and other desirable to obtain more or less complete vaporization of the water with normally no precipitation. y l a In the drawings of one embodiment of my f invention illustrated and described herein, Fig. 1V is a side elevation thereof; and Fig. 2, a vertical section of the same. Myv novel humidifying apparatus. comprises, Figs. 1, 2, a valve body or casing 1,
with a threaded cover 2, having in turn a Vhollow threaded neck 3, which receives a cap 4 i having adjustable connection therewith. Thecap 4 is apertured to receive the spindle 5 of a valve head 6, a spring 7 being coiled about the spindle 5, one end vseated against thel cap 4 'while the opposite end iS seated against the valve head 6, thus permitting adjustment ofthe tension against the head and consequent complete control of its movement. This construction forms a controller for the admission and mixture of the liquid and discharge of the' vapor having, among others, the advantages hereinafter ypointedfout.
The head 6 carries a stemsupporting member as a diaphragm 8 of thincopper or any suitable material which is firmly held between the opposed edges of the base 1 and topl 2. Y
Extended both outwardly and inwardly from one side of the valve body 1 is a `neck 9, the outer end being threaded to receive the pipe connection to be referred to. The neck contains a passage 10, the inner contracted end and outlet of which terminates :beneath the inner spindle end 11 and which seats thereover.
The neck 9 is adapted to be connected to any convenient source of water or other liquid supply and herein by means of an elbow 12, nipple 13 and union 14, the pastracted. A tine sieve 16 is secured across the interior of the union between its opposed edges. l
The bottom of the body 1 is tapped to receive a bushing 17 with a generous passage therethrough, which bushing in turn is iny teriorly threaded to receive a vapor gauge and vaporizing member in the form of a nipple 18 with a restricted passage 19 of suitable size. Obviously different nipples with y as follows lsage 15 through which is considerably con-Y passages of different sizes may be substituted at any time for special occasions or conditions, ther size of the passage determining substantially the amount of water to belva-y porized.
To ythe nipple 17 is secured the vaporizing head 2O of preferred construction, that shown herein comprising a long body with a lipv21 en its outer face, dischargeV apertures 22 thereabove, and a cap 28 on ,its lowerl end permitting access to the head if desired for any purpose. e
The body 1 is also apertured, Fig. 1, on its side wall and threaded at 24 to receive suitable connection with a source of fluid;
pressure, such as air or steam, not shown.
The operation of my Anovel vaporizer is he air pressure at the supply inlet may be thirteen pounds or greater, but
vit is usually desirable to keep it as low asvr possible for economyand from thirteen to fifteen poundsl are ,eifective for good results. Thek water or other liquid pressure .at the supply inlet may be vanything greater than fourteen or fifteen pounds, it being of little` importance so long as the pressure is a little .greater thanthe air pressure.
The valve 11 is closed andthe spring 7 adjusted as to tension so that it will maintain the valve 11 closed against the normal pressure ofthe water whatever that may be, but not againstany substantial increase of the water or combined water and air pressure. It is entirely possible to adjust the spring so accurately that almost any increase above the normal inthe water or water and air' pressure will open thevalve. yTo operate the humidifier, air pressureof approximately thirteen pounds is then admitted to the pipe 24 and 'when this air reaches the interior of valve chamber 1, it, with the water pressure of fifteen pounds on the lower end o f the spindle 5, acts to raise the same and open the orifice to the passage 10 permitting Water to flow therethrough and the mixed air and water after being substantially vaporized in the interior of the body l which is really a vaporizing member will escape from the apertures 22 in the head in the form of aV mist. l
Vaporization will continue until the air pressure is shut off when vaporization will stop instantly. Indeed it seems to make no difference whether the water pressure be slightly higher than the air pressure or many This construction is .f'ery'compact, simplel and efficient, will operate with low air pressure, thus being economical,- and produces extremely light vapor.
.This form of controller, requiring less piping than that, for instance shown in application Serial No. 346,425, is particularly advantageous iii cases Where the space is liniited, and Where the vaporizing head may be directly connected to the control, or connecting element for the air and fluid pipes and also where it is desired to have the installation as incoiispicuous as possible, as for instance Without the detachable mixing chamber 15 in my application above referred to.
It is also advantageous, Where it is necessary or desirable to operate it at a relatively loW'air pressure and relatively higher Water pressure for the reason that it is expensive 'to maintain high air pressure While it is usually practicable to obtain Water at any reasonable pressure. This form of vaporizer will operate at less air pressure because the air is not obliged to perform the carrying function that it performs to some extent Where the other form of construction above referred to is used. In such case the vapor is cairied through various lengths of pipe to the several heads, While 'in the presentv case the vapor is discharged directly from the valve chamber Which becomes the mixing chamber, to the head, Without the necessity for traveling through any intermediate length of pipe.
This invention is not limited to the particular embodiment thereof described and.
illustrated herein, but is lmore particularly pointed out in the following claims.
I claim- 1. Vaporizingy apparatus Vcomprising a controller having a mixing chamber therein, a Water inlet, a valve therefor, an air inlet, a compression member for the Water valve, and a vapor gauge for land leading from the mixing chamber of the controller; and a vaporizing head connected thereto.
k2. A' vaporizer comprising a controller having an air inlet, a Water inlet removed from the outer Wall of the controller, a valve for said Water inlet,coinpression means forV closing the valve against normal `Water vpressure, and a'vapor gauge on andcarried by the controller and communicating With the mixing Chamber; and a vaporizing head connected thereto.
l3. A vaporizingfcontroller having a mixing and vaporizingchamber,` and an aeriferin inlet thereto, a liquid inlet also there-l to, a cover for the chamber With an adjustable springseat` therein, a valve .normally seated on the liquid inlet With a stem extended into the cover, a spring Within the cover acting normally tovseat the liquid inlet valve, and a diaphragm on the stem tol bc acted upon by the fluidv in themixing chamber to assist in unseating the liquid valve. y
4t. The method of vaporizing-liquid Which comprises introducing an aeriform under pressure into a mixing and vaporizing chainbei, introducing under greater pressure with the aid of the' aeriform a liquid into said chamber, vaporizing the liquid therein byvl the aeriform, and ejecting the'same through a spraying head.
'5. A vaporizer comprising'a controller including the body 1, cover 2 therefor, air inlet 2li and liquid inlet 10 to the body, the valve.
stein 11 seated on said liquid inlet carrying the diaphragm 8 and spring' 7 for the stein, the cap 4l for the body and carrying the spring and stein, the outlet member 17 on theV body 1, gauge member 18 thereon; and
the head 2O `connected to the gauge.
In testimony whereof, I lhave signed my name to this specification. f
