Improvements in Utilizing the Heat Taken Up by the Water
employed for Cooling the Cylinders of Gas, Oil, or other Hydro-
carbon Motors.
We, JAMES EDWARDES WEYMAN of Treverward, Nightingale Road,
Guildford, Mechanical Engineer, and GODFREY WALTER HAYNES ELLIS, of
Shalford, Guildford, Tanner, both in the County of Surrey, do hereby declare the
nature of our invention for "IMPROVEMENTS IN UTILIZING THE HEAT TAKEN
UP BY THE WATER EMPLOYED FOR COOLING THE CYLINDERS OF GAS, OIL,
OR OTHER HYDRO-CARBON MOTORS" to be as follows:-
In gas, oil, and other hydro carbon motors, it is necessary to employ a large
quantity of water to cool the cylinders. The water so used is raised to a con-
siderable temperature, and in some cases, where water is scarce it has to be cooled
and used over again, in this manner a large amount of heat is wasted and the object
of our present invention is to utilize this heat for some useful purpose, as for
example, where the motor is employed for propelling a tram car or boat or like
vehicle or vessel, or when it is employed for driving machinery in a ròom, work-
shop, or other building, the heated water instead of being allowed to run to waste
or be cooled without utilizing the heat, we employ as follows:-
We cause such heated water to circulate through pipes. or equivalent appliances,
carried round or suitably placed in the tram car, boat or like vessel or vehicle,
room, workshop, or building as the case may be, so that the heat given off by
radiation may be usefully employed for heating and warming. The water being
gradually cooled in the course of circulation so as to be cool enough to be used
again for the primary purpose of cooling the cylinder or cylinders. In some cases
we effect this cooling process more effectually by extending the circulating pipes,
(after they have done duty for warming & heating purposes,) to the outside of the
tram car, boat or like vessel or vehicle, room, workshop, or building, so that they
may be brought into contact with the cooler atmosphere, (or in the case of a boat
or other vessel with the water on which it floats,) and in the summer time or warm
weather the circulation of the water could be restricted to these external pipes.
In cases where the motor is placed in a separate car or vehicle to the one where
the circulating pipes are required, we employ two separate systems for cooling the
water, one on the car or vehicle on which the motor is placed and one as above
described so that both or either can be used at will, we then employ instantaneous
couplings similar to those employed in railway carriages, for connecting the air,
gas, & water service pipes.

page_text: nature of our said invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
In gas, oil, and other hydro-carbon motors, it is necessary to employ a large
quantity of water to cool the cylinders. The water so used is raised to a con-
siderable temperature, and in some cases where water is scarce it has to be cooled
and used over again, in this manner a large amount of heat is wasted and the object
of our present invention is to utilize this heat for some useful purpose, as for
example, where the 'motor is employed for propelling a motor-car, tram-car, or boat
or like vehicle or vessel, or when it is employed for driving machinery in a room,
work-shop, or other building, the heated water instead of being allowed to run to
waste or be cooled without utilizing the heat, we employ as follows:-
We cause such heated water to circulate through pipes or equivalent appliances
carried round or suitably placed in the motor-car, tram-car, boat or like vessel or
vehicle, room, workshop, or building as the case may be, so that the heat given off
by radiation may be usefully employed for heating and warming-the water being
gradually cooled in the course of circulation so as to be cool enough to be used again
for the primary purpose of cooling the cylinder or cylinders. In some cases we
effect this cooling process more effectually by extending the circulating pipes,
(after they have done duty for warming and heating purposes,) to the outside of the
motor-car, tram-car, boat, or like vessel or vehicle, room, workshop or building, so
that they may be brought into contact with the cooler atmosphere, (or in the case
of a boat or other vessel with the water on which it floats), and in the summer-
time or warm weather the circulation of the water could be restricted to these
external pipes.
In cases where the motor is placed in a separate car or vehicle to the one where
the circulating pipes are required, we employ two separate systems for cooling the
water, one on the car or vehicle on which the motor is placed and one as above
described so that both or either can be used at will, we then employ instantaneous
couplings similar to those employed in railway carriages; for connecting the air, gas
and water service pipes.
In some cases we employ specially constructed couplings so arranged that as the
two halves of the coupling are brought together, suitable valves which are provided
in each half are pushed open by the action of coupling up, so that when they are
coupled up the cooling water is allowed to pass freely through the pipes and when
they are uncoupled the pressure of the water closes the valves in each half of the
coupling thereby preventing the escape of water either from the tram-car pipes or
the motor pipes.
The water for cooling the cylinders we cause to circulate through the cylinder
jackets and if necessary through the circulating pipes also, by employing a small
pump worked by the motor engine or by a pump driven independently, but we lay
no claim to this method of creating circulation.
As the principle of our invention is the same whether it is applied to a motor-
car, tram-car, boat, or like vessel or vehicle, room, workshop or building as the
case may be, the application to a tram-car motor and tram-car vehicle will suffice.
The nature of our invention will be better understood on reference to the
accompanying sheet of drawings in which,
Fig. 1, represents a motor-car and tram-car shewing the arrangement of warming,
cooling and circulating pipes.
Fig. 2, being an end elevation of the car.
Fig. 3, is a section shewing the specially constructed coupling coupled together,
both valves being open.
Fig. 4, is a section of one half of the same uncoupled shewing the valve closed.

Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we declare that what we
claim is,
1. In a tram-car or like vehicle propelled by gas, oil, or other hydro-carbon
motors, the arrangement and combination of parts and appliances for utilising the
heat taken up by the water employed for cooling the cylinders of such motors,
comprising the circulating pipes inside or inside and outside such motor-car or tram-
car with the couplings of either ordinary or special construction arranged so that
such circulating pipes can be employed either on the motor-car alone, or on the
motor car and tram-car together, and either inside or outside, or inside and outside
such motor or vehicle together or separately, in the manner and for the purposes
substantially as herein described and illustrated.
2. In a boat or like vessel or vehicle propelled by gas, oil or other hydro-carbon
motors, the arrangement and combination of parts and appliances for utilizing the
heat taken up by the water employed for cooling the cylinders of such motors,
comprising the circulating pipes arranged inside a boat or cabin or compartment of
the same by means of which the heat given off by radiation may be usefully
employed for heating and warming such boat, cabin or compartment, in the manner
and for the purposes substantially as herein described and illustrated.
3. In a room, workshop or building where a gas, oil or other hydro-carbon motor
is employed, the arrangement and combination of parts and appliances for utilizing
the heat taken up by the water employed for cooling the cylinders of such motors,
comprising the circulating pipes inside or outside or inside and outside such room,
workshop or building, by means of which the heat given off from the pipes
employed inside the same may be usefully employed for heating and warming, and
the pipes outside the room, workshop or building may be employed for cooling and
economising the water so employed, in the manner and for the purposes substantially
as herein described and illustrated.
