ig. 4 a detail or valve a, and
Fig. 5 a longitudinal section through a modification of the apparatus.
a is a cylindrical vessel divided into three compartments a¹, a², a³, by means of
a strainer a', and a transverse partition a³, which is perforated and provided with
valve a6, seated on tube a7.
The compartment a³, is adapted to be charged with salts or other chemicals
through hand hole as, and is by connection a, controlled by valve, a10, adapted to
be coupled to a water pipe. The water charged with the salt within compart-
ment a², passes through the strainer a¹, into the delivery compartment a¹, and
from thence by connection a", controlled by valve a¹², into the outer or fixed tube b,
of an injector, to be there mixed with the gas in the manner hereinafter described.
The compartment a³, is charged with gas through connection a¹³, and carries
pressure gage a¹. The gas outlet pipe a¹³, which enters the upper part of com-
partment a³, has a gas regulating valve a¹6, (Fig. 4) and communicates with the
inner longitudinally adjustable tube 6¹, of the injector, the nozzle of which dis-
charges into the fixed tube b. A coupling a", on end of tube a¹³, permits the gas
to be supplied to the injector from a source other than cylinder a.
In order to permit the relative proportions between gas and liquid to be regu-
lated, the tube b', is made longitudinally adjustable within tube b, so as to thereby
adjust the size of the liquid discharge passage formed within tube b, around the
nozzle of tube 61. To effect this adjustment, the tube 61, is made revoluble and
is suspended within a nut 63, supported on tube b. At its upper end the duct of
0.77

page_text: tube b', terminates in an annular groove 63, that communicates permanently with
the bore of tube a¹. By revolving, the tube bit will thus be raised or lowered to
regulate the discharge, the slight adjustment required being permitted by the
natural flexibility of pipe a¹5.
The water charged with gas flows from tube b, into a perforated thimble c,
through the small perforations of which the admixture is ejected in the form of a
fine spray. This spray enters a cylindrical chamber e¹, containing a number of
perforated superposed plates c², through the openings of which the mixture flows,
to be finally discharged into a bath tub through pipe 3. The perforated plates c²,
serve to still further sub-divide the spray and to break its force, so that the charged
liquid will flow into the tub in a quiet stream and not in the form of a turbulent
current.
If the gas has been used up to such an extent that the gas pressure within the
compartment a³, has fallen below the water pressure in compartment a², the valve
a, will open and water will flow into compartment 3, to displace the gas and drive
it out through the pipe a15. Owing to the elevated position of the mouth of such
pipe, this water will however be prevented from entering the same, and in this
way practically all the gas in compartment a³, can be used up. After all the gas
has thus been ejected, the water may be drawn out of compartment a³, by means
of a drain pipe a 18. The compartment a³, being thus relieved of its gas and freed
from water, is ready to be freshly charged with gas, that may be supplied from a
suitable source by connection a¹³
In practice, the charged cylinder a, is delivered to the consumer, who connects
it to the water service pipe of the water works, and uses the cylinder until the
gas has been used up, when it is exchanged for a charged cylinder. In this way
the preparation of effervescent baths is greatly facilitated and such baths are put
within the reach of the occupants of hotels and dwelling houses generally.
In Fig. 5, the vessel a, is replaced by a vessel d, for the water and a separate
vessel e, for the gas. The water is supplied to vesel d, through tube d, that
extends to within a short distance of the bottom of the vessel, so that the water is
brought into contact with the chemicals placed into the vessel.
The vessel d, connects by pipe d², with the outer tube b, of the injector, while the
vessel e, connects by hose e', with the inner or longitudinally movable tube b¹, of
the same.
In this modification the longitudinal adjustment of tube b', is shown
to be effected by means of a hand lever f, fulcrumed to a fixed support f¹, while a
stuffing box f2, holds the tube at any elevation at which it may be set.
It is clear that the invention may be applied to different purposes from the one
specified, it being adapted generally for the admixture of volatile or semi-volatile
or gaseous substances with liquids.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is:-
1. A mixing apparatus composed of a cylinder divided into a gas chamber and
a water chamber, and of an injector that is connected to said chambers and is
adapted to mix the gas with the water, substantially as specified.
2. A mixing apparatus having a cylinder which is divided into
gas chamber
and a water chamber by means of a perforated partition having a valve which is
opened upon an excess of the water pressure over the gas pressure, substantially
as specified.
3. A mixing apparatus having a cylinder which is divided into a gas chamber,
a water chamber, and a delivery chamber, by means of a perforated partition
between the gas chamber and the water chamber, and by a strainer between the
water chamber and the delivery chamber, substantially as specified.
4. A mixing apparatus composed of a cylinder which is divided into a gas
chamber and a water chamber by means of a perforated partition having a valve;
and of an injector composed of a pair of tubes that communicate with said chambers
4

page_text: and of which the inner tube is longitudinally adjustable to regulate the propor-
tions of the gas and water, substantially as specified.
5. In a mixing apparatus, an injector composed of an outer tube, an inner tube,
a perforated thimble at the bottom of the outer tube, and a discharge nozzle having
a series of ducts and arranged beneath the thimble, substantially as specified.
6. In a mixing apparatus, an injector composed of an outer tube, an inner longi-
tudinally adjustable tube having a discharge nozzle, means for adjusting the inner
tube, a perforated thimble at the bottom of the outer tube, and a nozzle having
a series of ducts and arranged beneath the thimble, substantially as specified.
7. An apparatus for mixing liquids with gases, constructed substantially as
herein shown and described.
