COMPLETE SPECIFICATION.
Improvements in the Method of and Apparatus for Generating and
Applying Vapours.
I, OREON STAPLES RHODES, Physician, of Washington Street East Stroudsburg,
in the County of Monroe, and State of Pennsylvania, United States of America, do
hereby declare the nature of my invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
The invention relates to the generation of vapours of volatile liquids, and to
motors driven by such vapours and. it has for its object to provide a new and
improved apparatus for generating and applying vapours, whereby the fuel is
utilized to the greatest advantage and the danger of explosions is reduced to
a minimum.
The method consists principally in heating a boiler fluid to form a heating
medium for transmitting heat to a chemical contained in a separate receptacle,
so that the chemical is expanded and forms the motive agent for driving
the motor.
The apparatus consists of a generator comprising a closed receptacle adapted to
contain the chemical to be vaporized to form the motive agent, and a boiler
surrounding the said receptacle, and adapted to contain the heating medium for
heating the receptacle and the chemical contained therein.
The invention also consists of certain parts and details and combinations
of the same, as will be fully described hereinafter and then pointed out in
the claims.
Reference is to be had to the accompanying drawings forming a part of this
Specification, in which similar letters of reference indicate corresponding parts in
all the figures.
and
Figure 1 is a cross section of the apparatus.
Figure 2 is a side elevation of the same, with the shell in section;
Figure 3 is a sectional plan view of the same, on the line 3-3 of Figure 1;
Figure 4 is an enlarged transverse section of the engine, on the line 4-4 of
Figure 2.
In order to carry the above described method into effect, I prefer the construction
of an apparatus as shown in the drawings, the said apparatus being provided with
a closed receptacle A, adapted to contain a chemical such as ether, to be volatilized
to form the motive agent, as hereinafter more fully described. This receptacle A
is completely surrounded by or enclosed in a closed boiler B, made tubular in its
lower portion, and having the vertically disposed legs B', B and B³, connected
with each other by a series of horizontally-disposed arms B₁ from which as well as
from the leg B', extend the short boiler tubes B³, capped at their outer ends, as
plainly indicated in the drawings.
The lowermost horizontal arm B of the tubular portion of the boiler B is
supported in bearings C, attached to the top of a furnace D containing a fire box E,
and mounted on a suitable base F. A shell G, likewise set on the furnace D,
surrounds the boiler B ; and through this shell passes the smoke and gases of the
fuel burning in the fire box, so as to heat the fluid contained in the boiler B and the
tubular extensions thereof, before passing to the smoke stack G¹ extending from
he top of the shell G.
The chemical employed is preferably in fluid form, and is passed by a pump or

page_text: other similar device, into a pipe H discharging into a central chamber l' formed in
a box I in the lower end of the central leg B', as plainly shown in Figures 1 and 3
From the top of this chamber in the box I, leads a pipe J which extends
vertically in the leg B' and which discharges into the bottom of the receptacle A,
so that the chemical passes from the pump through the pipe H into the chamber I'
and then through the pipe J into the receptacle A in which it is volatilized by the
heated boiler fluid surrounding the said receptacle A and the pipe J as well as the
box I.
Into the receptacle A and near to the cap A¹ thereof, extend the vertically-
disposed outlet pipes J¹ and J' passing through the bottom of the receptacle A
down the leg B1, and connecting at their lower ends with the chambers I' and I'
formed in the box I on the opposite sides of the central chamber I'. The side
chambers and I are connected by pipes K and K with the chests of the
engines L and L₁ respectively, secured on opposite sides of the furnace D, as
is plainly shown in Figures 1, 2 and 3. Thus the vapors generated in the
receptacle A can pass through the pipes J', J', chambers 12, 1 and pipes K, K', to
the engines L, L, to drive the same in the usual manner. The pipes K, K' have
the usual valves K, K³ to regulate the passage of the vapor from the receptacle A
to the cylinders.
The cylinders are provided with jackets through which circulates the boiler fluid,
and the sides of the furnace D are formed with compartments D' and D' opening
into the said jackets, and connected with the legs of the boiler, so that the boiler
fluid can circulate through the jackets surrounding the cylinders, to prevent loss of
heat while the vapors are doing their work as the motive agent in the cylinders of
the engines L and L. The exhausted vapors pass from the engines through
pipes N to a condenser of suitable construction, to be condensed and forced by the
pump back into the pipe H to be used over again by being volatilized in the
receptacle A as previously explained.
It will be seen that by the construction described, the generator is very simple
and compact in construction and the boiler and engine form but one machine and
both make use of the same boiler fluid. The construction is such that the fire from
the furnace D is directly beneath and in contact with the lower end of the boiler,
and the heat in passing to the chimney must necessarily pass over a great surface
of the boiler containing the boiler fluid, so that the latter is raised to a bigh
temperature and is kept there at a comparatively less expense for fuel than by the
methods heretofore employed.
•
The boiler fluid is preferably a fixed oil having a boiling point at a high
temperature, so that the fluid gives a great heat without corresponding pressure,
and hence reduces the danger of explosion to a minimum.
The
The vapor generator in the form of the receptacle and the pipes connected
therewith, is such as to withstand any pressure of the vapor generated.
vapor is generated from a volatile liquid combined with a soluble gas, a volatile
liquid, or a liquefied gas.
