Improvements in Combined Gas Engines and Carburetters.
I, HERBERT JOHN ALLISON, of 52 Chancery Lane, London, it the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention. (which has
been communicated to me from abroad by Lyman F. McNett, of Yonkers, New
York, United States of America, Gentleman,) and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
My invention relates to an organization of apparatus in which water is circulated
in such manner as to keep the cylinder of a gas engine cool, and to heat a gas
generator for carburetting air with naptha or other volatile hydrocarbon to make
gas.
My invention consists in the combination of apparatus hereinafter described and
comprising exhaust and inlet pipes properly arranged between a jacket for the
gas engine and a jacket or reservoir for a gas generator by which air may be
carburretted with naptha or other volatile hydrocarbon, as will be hereinafter more
fully described.
The cylinder of a gas engine must be kept cool while in operation which is
ordinarily done by allowing cold water to pass through a chamber or jacket which
surrounds the cylinder of the engine, the water being supplied by a pump or tank.
By this system a large amount of water is wasted. To save this expense and avoid
the carrrying of a large amount on cars which are propelled by gas engines I use
the water over and over again, utilizing the heat of the water as it comes from the
chamber or jacket of the engine to generate naptha or other hydrocarbon gas in a
generator provided with a water jacket, which generator in turn cools the water
and causes it to be returned to the chamber or jacket of the engine on the principle
of the difference in density or gravity of hot and cold water.
In the accompanying drawings:-
:-
Fig. 1, shows apparatus embodying my invention, the gas engine being shown in
side elevation and the carburetter and appliances used therewith in longitudinal
section.
Fig. 2, is a cross section on the line X, X, of Fig. 1.
Fig. 3, is a cross section on the line Y, Y.
A generator D, of the kind hereinafter described or of any other suitable character
is wholly or partially surrounded by a jacket K, as shown, being formed of outer and
inner walls A, R, with ends a. The outer wall or shell A, is provided with double
heads forming spaces L, L, which serve as a protection for the various appliances
used in the construction.
This reservoir or jacket K, receives the heated water through the pipe B, as it
comes from the jacket or chamber H, surrounding the cylinder G, of the gas
engine.
The generator D, consists of a cylinder mounted on a hollow perforated shaft V,
which is provided with a pulley m, by which the cylinder may be rotated. The
cylinder D, rotates in a chamber O, containing a volatile hydrocarbon and is provided
with a series of floats d, made as absorbents and consisting of woven wire or cloth
filled with some absorbent material and attached to the inside of the cylinder D.
The cylinder D, is made of open work, as for instance of woven wire or of a sheet of
perforated material like iron. The floats d, take up the naptha in the chamber O, and
distribute it or allow it to fall in fine streams or as drops in the space in the upper
part of the cylinder.
J, is an inlet which permits the air to be forced into the carburetter through
the hollow shaft, and N, an outlet through which the carburetted air is carried
away for use.

page_text: The pipe B, is the exhaust for the heated water to pass out of the chamber H, of
the engine and connects with the reservoir K, as shown in Fig. 1. By this means
the hot water is allowed to drip over the shell of the generator and heats the naptha
more readily and then as it becomes cold, settles and passes out by the exhaust pipe C,
into the chamber H, at L. Thus a circulation is kept up between the engine E, and
the reservoir or jacket K, the explosion of the gas in the cylinder G, heating the
water in the chamber or jacket H, and causing it to pass through the pipe B, to the
jacket where it becomes cold by heating the naptha and forming gas when it is
returned to the jacket H, again.
My invention is designed especially for application to gas engines which are used
to propel cars or vessels and are supplied with gas manufactured on the car or vessel
as often as it is needed. I do not, however, limit myself to this special application of
the invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and the manner in which the same is to be performed, I declare that what I
claim is :-
:-
The combination, substantially as described, of a gas generator, a jacket therefor, a
gas engine having a cooling jacket, and circulating pipes as described for circulating
a heating and cooling fluid through the jacket of the engine and the jacket of the
generator.
