COMPLETE SPECIFICATION.
Improvements in Ammoniacal Gas Engines.
We, HARRIET ELIZA BLACK, Broker, of 49 Poeyfarre Street, in New Orleans,
Parish of Orleans, and State of Louisiana, United States of America, and LUCYNTHA
MASON, Broker, of 336 St. Andren Street, in New Orleans, Parish of Orleans,
and State of Louisiana, United States of America, do hereby declare the nature of
our invention for IMPROVEMENTS IN AMMONIACAL GAS ENGINES and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
Reference being had to the accompanying drawings with the letters of reference
marked thereon and made a part of this specification, in which,
Figure 1 is a slide elevation of a railway-car, with a portion of its side broken
away to show the improvement when attached to it as a motor.
Figure 2 is a plan view.
Figure 3 is a vertical sectional view of the condenser and its attachments.
Figure 4 is a vertical sectional view of the artificially heated chamber or vaporizing-
vessel with its heating attachments.
Figure 5 is an end view of a car with the invention attached.
Figure 6 is a plan and side view of a pipe to connect the pump and tank used for
storing the condensed vapor.
The object and purpose of this invention are to develop an expansive vapor
medium, to be applied as motor force or power, by causing the production of vapor
only in the quantity sufficient for immediate use at the time when the same is
required, by injecting, by mechanical means, a sufficient quantity of liquid anhydrous
ammonia into an artificially heated chamber or vaporizing vessel in regulated
quantities, so adjusted as, when vaporized, to produce sufficient vapor, of sufficient
expansive force, to perform the labor or secure the force necessary to operate the
motor, as, for example, to accomplish a stroke or half stroke of an engine of the
character of a steam engine; also, in the condensing of the artificially heated vapors
in a jet-condenser, in about the same manner as is done in a condensing steam
engine, and in the emptying out of the condensed vapor in liquid form from the
condenser, and storing it in a suitable receptacle, by mechanical means, at each stroke
or half stroke of the engine.
Like letters indicate like parts in all of the figures.
A represents a railway car.
B. represents the platform of a car.
D represents a motor engine.
E represents a suitably grooved driving wheel, secured onto the driving or crank
chaft

page_text: I represents the discharge pipe through which liquid ammonia is injected, by the
force pump, into the artificially heated chamber or vaporizing vessel.
M represents a pipe through which the vapors are exhausted into the condenser.
N represents the condenser.
N¹ represents a perforated plate placed inside and near the top of the condenser,
to spray or divide the injection water in jets.
P represents a lift and force pump for drawing water through a suitable supply pipe
from the water reservoirs, and by the same stroke inject it into the condenser through
pipe P¹
R-R represent water reservoirs used for carrying water for condensing purposes.
O represents a lift and force pump for pumping the condenser vapors in liquid form
from the condensers through pipe O, and by the same stroke send it on through
pipe O2 into the storing tank 0³ ³.
The construction is as follows:
The engine can be of any of the well known varieties, of the horizontal or vertical
engines, and of any approved kind of valve or valve motion. The artificially heated
chamber or vaporizing vessel can be constructed of iron or steel, and of any shape
or size, but with strength of construction sufficient to resist an expansive force of
two hundred pounds to the square inch, and with the artificial heating arrangements
so manageable that any desired temperature can be attained, maintained, or
suppressed at will.
The operating is as follows.
The reservoir K is charged with liquid anhydrous ammonia, and the reservoirs RR
are charged with water. Then light the lamp or gas jet I², placing it under the
chamber or vaporizing vessel I to heat it by artificial means. Then adjust and
regulate the different supply cocks, and give the engine revolution by hand, which
will cause the pump L to be actuated to draw a regulated quantity of liquid
anhydrous ammonia from the reservoir K, and by the same stroke inject into the
artificially heated chamber or vaporizing vessel I, where it will be instantly converted
into vapor artificially heated and of great expansive force. It is then admitted
through pipe I', into the engine D thus causing the engine piston to be moved to
make a stroke or a half stroke, and the vapor will then be exhausted from the engine
into the condenser, the same as is done in a condensing steam engine; and the
pump P will be drawing the required amount of water from reservoirs R R, and by
the same stroke inject it into the condenser N through the perforated plate N¹, and
it will be instantly condensed or absorbed by the water, and is then pumped out of
the condenser by pump O and stored in the tank 03 0³, from whence it will be drawn
off at a proper time and place for generation and liquefaction previous to use again
and continuously.
It can readily be seen that our improvement is quite different from all others,
viz. We can obtain and maintain any desired temperature or expansive force that
may be desired, and with a degree of exactness under all rates of speed and resist-
ance to be overcome; and the condensing of vapors will be uniform and regular
at all times, for the condensing water is variable in quantity and so regulated at
each stroke to suffice for condensing the amount of vapor just exhausted from the
engine into the condenser, and a vacuum or partial vacuum will be formed in the
condenser and maintained there but with slight variation while the engine is in
motion.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :
1. The combination of the artificially heated chamber or vaporizing vessel I with
pipe I and pump L, all constructed substantially as described, and for the purposes
set forth.
2
The combination of the artificially hosted chambor or vaporizing wel I with

page_text: pipe I, engine D, exhaust pipe M, and condenser N, all constructed substantially as
described, and for the purposes set forth.
3. The combination of the pump P with water reservoir RR, condenser N, pump 0,
and storing tank 030³, all constructed substantially as described, and for the purposes
set forth.
