"A NEW OR IMPROVED APPARATUS OR HYDRO GAS INJECTOR,' FOR MAKING
ACIDULATED OR EFFERVESCENT DRINKS OR MEDICATED WATERS, OR FOR EXTIN-
GUISHING FIRES AND OTHER PURPOSES." A communication from abroad by Antony
Gauchet, of Brussels, in the Kingdom of Belgium, Engineer.
This Invention as communicated to me relates to apparatus called "hydro gas
injectors," for producing gas from suitable chemical agents by means of a current of
water, steam, or air, and mixing or combining the said gas with or dissolving it in
the said water, steam, or air for the purpose of making acidulated or effervescent
drinks or liquids, medicated waters or baths, or for extinguishing fires.
The said apparatus consists of an injector provided with a double cone and of
The
one or several vessels or receptacles containing the chemical agents employed.
injector draws the solutions or liquids from the vessel or vessels and projects them
forward as required for the purposes for which they are intended.
When water under pressure is used as the actuating means, and carbonic acid gas
is to be produced and combined with the water, the injector is mounted by preference
between two receivers or vessels, the one containing powdered bicarbonate of soda,
the second a suitable acid; the said injector by means of suitable pipes and cocks
or valves communicates with each of the said receivers both at top and at bottom,
or at any other suitable parts. When water under pressure is caused to flow into
the said injector it is first made to pass into the said receivers so as to dissolve the
powder they contain (if the chemical agents employed be in the form of powder),
the water is then made to flow through the injector. By passing through the
first cone it creates a vacuum, which draws in the solution of bicarbonate of soda
from one of the receivers, and the water becomes charged with bicarbonate of soda,
When passing through the second cone the water in like manner becomes charged with
acid from the second receiver, and the combination of the bicarbonate with the acid
produces carbonic acid gas, with which the water becomes charged. The continued
flow of water under pressure into the injector, produces a continuous jet from the
fore end of the said injector, which when the apparatus is intended for extinguishing
fires is provided with hose and a suitable pipe or nozzle.

page_text: If preferred four or any other suitable number of the said receivers may be used
instead of two, so as to render tlie action of the injector continuous by replacing each
pair of receivers as they are emptied by fresh ones.
Instead of the receivers being charged with bicarbonate of soda and acid as
herein-before described, tlie said receivers may contain any other suitable ingredients
or chemical agents which it may be required to mix and combine together and with
water for making acidulated or effervescing drinks or other liquids or medicated
waters or for other purposes.
Instead of being actuated by water under pressure the apparatus may be arranged
so that a jet of steam or air passing through a cone placed before, behind, or between
the two water cones herein-before described will draw into the injector and
communicate motion to the water required for the working of the hydro gas
injector.
