PROVISIONAL SPECIFICATION.
Improvements relating to Motor Driven Vehicles.
I, JOHN BRADLEY CARSE, of 64 and 66 Wabash Avenue, Chicago, Illinois'
United States of America, Mechanical Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to vehicles driven by internal combustion engines which
require the working cylinder to be kept cool by water circulating in a jacket.
Heretofore in connection with such engines and vehicles there has been provided
but one reservoir for the cooling water. It is my experience that one reservoir is
not satisfactory since after the engine has been working some time the cooling water
becomes so hot that its efficiency as a cooler is considerably impaired and it becomes
necessary to apply ice or other cooling medium to the cylinder. According to my
invention I overcome this objection by providing two reservoirs for cooling water
and in some instances three or more reservoirs 30 arranged that either or any one
of the reservoirs can be put into communication with the cylinder jacket by turning
a tap, while the other or others is or are shut off from the jacket.
As soon as the water in one reservoir becomes unduly heated I shut off that
reservoir and turn on another reservoir and so keep the jacket supplied with
comparatively cold water. The hot reservoir will have time to cool down before
it is required to be used again. I so construct and place the reservoirs in relation
to the vehicle that when the latter is in motion the atmosphere will play on the
reservoirs and will act as an efficient cooler of the water therein. With my
improvements it is not necessary to apply ice to the cylinders even after a run of
several hours duration. My improvements are equally applicable whether the engine
has one cylinder only or whether it has two or more cylinders.

Improvements relating to Motor Driven Vehicles.
1, JOHN BRADLEY CARSE, of 64 and 66 Wabash Avenue, Chicago, Illinois, United
States of America, Mechanical Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention relates to road vehicles driven by gas or oil or like internal
combustion engines which require the working cylinder to be kept cool by water
circulating in a jacket.
Heretofore in connection with such engines and vehicles there has been provided
but one reservoir for the cooling water. Now I have found that one reservoir is not
effective for the purpose since after the engine has been working for some time the
cooling water becomes so hot that its efficiency as a cooling medium is considerably
impaired and it becomes necessary to apply ice to the working cylinder in order to

page_text: prevent excessive heating thereof. By my invention I overcome the aforesaid
objection to the use of a single cooling reservoir and this I do by providing two
reservoirs or in some instances three or more reservoirs of cooling water and so
connecting the same to the cylinder jacket by means of taps or cocks that only one
reservoir is in use at any moment, while the water in the other reservoir or reservoirs
is being cooled by the atmosphere. As soon as the water in the reservoir in use
becomes heated to such an extent as to be inefficient as a cooler the communication
between that particular reservoir and the jacket is closed and that between the other
reservoir or one of them if there are several is opened. The reservoirs are so
constructed and arranged on the vehicle that when the latter is in motion the
atmosphere will play on the reservoirs and act as an efficient cooler of the water
therein.
In the accompanying drawings I have shown in side elevation two reservoirs
with their communication pipes constructed in accordance with my invention.
A, A' are the two reservoirs, B, B₁ are the outlet pipes leading therefrom, and
C, C are the inlet pipes. The pipes B, B¹ are coupled by a three-way cock D to
which is connected the pipe E leading to the cylinder jacket, and the pipes C, C¹ are
similarly coupled by a three-way cock F to which is connected the pipe G leading
from the cylinder jacket. The plugs of the cocks D, F are furnished with short
arms D, F which are connected together by a link H so that the cocks are
opened and closed in unison. J is the handle for operating the cocks. Each of
the reservoirs A, A' may be conveniently made of upper and lower boxes a, a¹
connected together by tubes a² so as to expose a large surface to the cooling
action of the atmosphere. The water entering the top box a passes down through
the tubes a into the lower box a' and in its passage is rapidly cooled. Other
forms of reservoirs may be used.
The action of the aforesaid apparatus is as follows, that is to say, by turning the
handle J the reservoir A for example may be placed in communication with the
cylinder jacket and the communication between the reservoir A¹ and the cylinder
jacket cut off, so that only the water in the reservoir A will be available for cooling
purposes. When this water becomes unduly heated the handle J is turned so as to
reverse the connections thereby placing the reservoir A¹ in communication with the
jacket while communication between the reservoir A and the jacket is shut off.
The water in the reservoir A is then cooled by the contact of the atmosphere with the
tubes a so as to be ready for further use by the time the water in the reservoir A¹
becomes too hot. The reservoirs are thus used alternately. If there are more than
two reservoirs, they are used in turn.
With the aforesaid improvements it is not necessary to apply ice to the
cylinder even after a run of several hours duration. My improvements are equally
applicable whether the engine has one cylinder only or whether it has two or more
cylinders.
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 1
claim is :-
In a road vehicle driven by an internal combustion engine, two or more reservoirs
for cooling water and communicating pipes and cocks whereby either or any one of
the reservoirs may be placed in communication with the cylinder jacket while the
communication between the said jacket and the other reservoir or reservoirs is cut off,
substantially as described, and for the purpose specified.
