Improvements in Gas and like Motor Engines.
I FRANK LISTER of Keighley in the County of York, Consulting Engineer, do
hereby declare the nature of this invention to be as follows, that is to say
:-
In engines deriving their power from the combustion of gas, or the like within
their cylinders, it is well known that these cylinders and their pistons and parts
in connection therewith are by the said combustion, heated to a high degree and
that if means, such as water-jacketing the cylinder etc., were not employed the
motor parts and the surfaces of those in contact with them would very rapidly
deteriorate as has often been found in practice.
Now when cooling agents are employed for keeping the parts at a desired
To obviate this
temperature, all the heat generated in excess of this, is wasted.
waste as far as possible and yet maintain the parts at a given normal temperature
is the object of this invention and this I attain in the manner hereinafter set
forth.
The engines may be of any of the well known kind as at present constructed
but in connection with these I arrange means whereby I can inject water into the
cylinder at the time this said cylinder has become heated to a certain degree,―
this water being by the heat of the cylinder converted into steam and at a time
when it is most beneficial as a motor for the piston, thus while it reduces the
temperature thereof it also utilizes the heat.
In a single acting engine the admission of water as above described may be
arranged and regulated to take place in the alternate cycle to that in which the
gas or like combustible force-generating-medium is used or it may be at every
third, fourth or other proportionately and relatively arranged rate of supply.
Or instead of the water being admitted at prearranged intervals its supply
may be governed by heat indicating mechanism, as a copper or other metal tube
in contact or connection with the cylinder, or a column of mercury, or other
liquid, metal or gas may be used these being so arranged and the parts in con-
nection with them so constructed that on the temperature of the cylinder exceeding
a certain degree their expansion, thereby, opens a valve or otherwise acts so that
the water is admitted as desired.
In a single acting engine the water is never supplied to the cylinder simul-
taneously with the supply of the gas nor at any time while said gas or explosive
mixture is in the cylinder, the mechanism for admitting the water being arranged
so that when it operates to enable such, it also operates to close or prevent the
admission of gas.
In a double acting engine or one in which the cylinder is closed at both ends the
actions of the water and gas are exactly the same as herein before described when
one end of the cylinder in these double acting engines is considered or taken
as being distinct and separate from the other so far as its cycle of actions are
concerned.
Or again one end of the cylinder in these double acting engines may be used
exclusively for the gas while the other end is used for water.

I, FRANK LISTER of Keighley in the County of York, Consulting Engineer,
do hereby declare the nature of this invention and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement, that is to say :-
In engines deriving their power from the combustion of gas or the like within
their cylinders, it is well known that these cylinders and their pistons and parts in
connection therewith are by the said combustion, heated to a high degree and that
if means such as water-jacketing the cylinder etc., were not employed the motor
parts and the surfaces of those in contact with them would very rapidly deteriorate
as has often been found in practice.
Now when cooling agents are employed for keeping the parts at a desired
temperature, all the heat generated in excess of this temperature, is wasted, and
to obviate this waste as far as possible while yet maintaining the parts at a
given normal temperature is the object of this invention and this I attain by the
devices hereinafter described and illustrated by the accompanying drawings, in
which :-
Fig. 1 is a side sectional elevation of a sufficient portion of the cylinder of an
engine with certain of the other parts in connection with it to show the application
of my invention.
Fig. 2 is a similar view to Fig. 1 but illustrates another arrangement of the
parts for effecting the desired results.
Fig. 3 is also a similar view to Fig. 1 illustrative of a modification hereinafter
explained.
Fig. 4 illustrates certain of the parts shown by Fig. 3 but in different relative
positions.
The engines may be of any of the well known kind as at present constructed but
in connection with these arrange means whereby I can inject water into the
cylinder at the time this said cylinder has become heated to a certain degree, this
water being by the accumulated heat of the cylinder converted into steam and at a
time when it is most beneficial as a motor for the piston, thus while it reduces the
temperature thereof it also utilizes the heat.
In accordance with my invention water is supplied to the cylinder a through the
pipe while oil or gas is supplied thereto by the pipe c, the admission of each
or both being regulated by the governor d which is shown as of the usual
66 momentum type or other well known styles of governors or means may be
employed in the usual manner as is well understood. However in order that the
desired liquid or gas may be admitted at the proper time, that is to say provided
the temperature of the cylinder a has been increased to the maximum point by
continued or successive charges of oil or gas being admitted through the pipe c and
exploded therein an expanding substance at e (which is shown in the drawing as
being a body of liquid as mercury, although an expanding tube of any desired
metal as copper or the like may be employed by arranging the motor parts in
connection with it to act as desired, as will readily be understood) forces the
piston fin an upward direction so as to cause the lever g to move the plug h
sufficiently for the opening h¹ made therein to move out of line with the opening c
of the pipe
chence the passage of the oil or gas through the said pipe c is thus
arrested, while the opening 2 in said plug h will be brought opposite the opening b

page_text: in the pipe 6 by which water may now be admitted whenever the speed governor d
operates the valve k. The return movements of the plugs h and k are effected by
the springs and k¹.
As an alternative method the oil or gas and water may be admitted to the
cylinder a by means of valves operated through the rods m and n, thus when the
temperature of the cylinder a is low enough for the mercury at el (see Fig. 1) to
draw down the piston f¹ sufficiently for it to bring the lever g' with its extending
end opposite the rod m on the governor d striking the lever k said rod m will be
moved and oil or gas will be supplied to the cylinder a. And when the
temperature of the said cylinder a has been increased to cause the mercury e¹ to
expand and raise the lever g' so that its said extending end is opposite the rod n at
this time when the governor d moves the lever k³, the said rod n will be moved and
so water will be supplied to the cylinder a.
Now provided that the admission of the water is desired to take place at a
different part of the cycle to that at which the gas or oil is usually admitted, it
will readily be seen that this may easily be effected by having a separate cam for
moving the governor or otherwise operating the valve for admitting the water as
desired.
In all cases the air admission and exhaust valves are suitably arranged to open
and close at the proper times in relation to the actions of the water injections and
gas explosions.
To prevent the possibility of the plug h or the lever g¹ remaining in the space
between the openings cand and the rods m n respectively on or by which
neither the gas or oil or the water would be admitted to the cylinder a however
the governor d indicated, I make use of au arrangement of means shown by
Figs. 3 and 4 whereby when any change of position of the lever g³ takes place such
change is quickly effected.
This attain by causing the rear end of the lever g' to press against the rotary
camp which is mounted upon the governor's cam shaft d¹ but which is arranged to
act at the contrary time to said governor's cam d³, said pressure of the lever g
against the camp being effected by the spring 9. From this it will be seen that
as the shaft d¹ revolves, the lever 9 is as continually oscillated yet since the cam p
operates at a contrary time to the acting of the cam da, unless this lever is held
up when raised by its said cam p it will descend along with same and will always
allow the lever g² to have its extending end opposite to, in order thus to operate,
the rod n (the position of which and that of the rod m are now exchanged) and so
supply water to the cylinder a. But by arranging the lever g³ to slide the notched
block as it is moved by the actions of the springs as the mercury e decreases in
volume and allows the plug f to descend, immediately said block is sufficiently
freed to be moved by said spring 8, it is brought under the lever which
it will retain in its raised position as shown by Fig. 4 on which whenever it is
moved by the governor d the rod m is struck and oil or gas is admitted to the
cylinder a.

In double acting engines or those wherein the cylinder is closed at both ends
the oil or gas admission valves etc., may be arranged so as to supply same to
one end of the cylinder while those of the water are arranged to supply it to
the other end of the cylinder, thus one end of the cylinder will be used exclusively
for the oil or gas while the other end is used for the water.
Arrangements are preferably made for conducting the exhaust gases to the
water tank for the purpose of heating the water before using it in the cylinder
by which means any vapour that such gases may contain, is condensed while the
beat therefrom is utilized.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. In combination with a gas or oil engine, means for automatically supplying

exceeds a given degree substantially as herein specified.
