COMPLETE SPECIFICATION.
Improvements in Motor Engines Operated by Gas, Oil, or other
Explosive Agent of Power.
JAMES LITTLEJOHN, Engineer, 23, Hartington Road, Aberdeen, and WILLIAM
ROBERT LAING, Engineer, 11, Ferryhill Terrace, Aberdeen, 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 state-
ment
-
This invention has reference to the type of motor engine, vertical or hori-
zontal, with one or more cylinders, operated by gas, oil or any such like
explosive agent of power and used for stationary driving power, propelling
motor cars, omnibuses, or for other locomotive purposes.
Our improvements in such engines refer to the mode of construction and to
the method of cooling the cylinder, combustion chamber, valves, and such like
parts as become heated by the rise in temperature occasioned by the explosion
of the agent of power.
In the construction of such an engine according to our invention, the said
cylinder and such like parts are completely immersed in a vessel containing
sufficient water to keep them at a normal temperature. This vessel forms part
of, or is fixed by some suitable method to, the bed plate or base of such an
engine.
Having now shown the nature of our invention we will proceed to describe
the same more fully by making reference to the sheet of drawings wherein is
shown a side elevation and a horizontal plan of our improved method of con-
struction. In Fig. I, the cylinder B, along with combustion chamber D are
secured to the water vessel A, by flanges G, H, and I, J, or by other suitable
method. In Fig. 2 the cylinder B, and combustion chamber D, are shown fixed
to water vessel A, within a suitable distance from a side of the said water
vessel A, to allow of the operation of necessary gearing for opening and closing
valves, governing and such like, or in any suitable position within said water
vessel A. The cylinder B, is secured to the bedplate or base C, by flanges G,
and H, or by other suitable method.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is;
-
Firstly, In an engine operated by gas, oil or such like explosive agent of
power, the combination therewith of a water vessel secured to or forming part of
the bed plate or base of engine and allowing of the complete immersion in
water of the cylinder, combustion chamber, valves and such like parts which
become heated by the explosion of the agent of power.
Secondly: In an engine operated by gas, oil or such like explosive agent of
power, the method of cooling the cylinder, combustion chamber, valves and such

page_text: like parts as become heated by the explosion of the agent of power, by their
complete immersion in water.
Thirdly In an engine operated by gas, oil or such like explosive agent of
power, the method of constructing such an engine without water-jacketing such
parts as are liable to become heated by the explosion of the agent of power.
Dated this 25th day of March 1899.
