Improvements in the Valve Boxes of the Vaporizers of Oil Engines.
We, STEPHEN BALLARD and ERNEST BALLARD, both of Colwall, Malvern, in the
County of Worcester, Malt Vinegar Brewers, and JOHN GOODE, Temperance Hotel,
Colwall, Malvern, aforesaid, Fitter, do hereby declare the nature of our said invention
and in what the same is to be performed to be particularly described and ascertained
in and by the following statement:—
Our invention has for its object improvements in valve boxes for oil engines and is
specially applicable to that class of oil engines where no ignition tube is used but can
with equal advantage be applied to other kinds of oil engines. Hitherto it has been
found with the class of oil engines where no ignition tube is used that the hole in the
valve box through which the oil passes to the vaporiser constantly becomes choked
with carbon thus stopping the engine which is a source of great inconvenience and
loss of time as it necessitates the valve box being taken to pieces. Now by our
invention we are enabled to always keep the hole through which the oil is
sprayed into the vaporiser free from carbon thus allowing the oil to pass freely
through.
In order that our invention may be more clearly understood and more easily carried
into practical effect we have appended hereunto a double sized sheet of drawings
upon which we have shewn a part sectional view of a valve and valve box with our
improvements applied thereto. The major portion of the valve box forming no part
of our invention as our invention would be equally applicable to other forms of valve
boxes which have an outlet hole requiring to be kept clear.
A is the valve box surrounded by the water jacket W with its inlet W¹ and
outlet W2. Inside this valve box is fitted the sleeve a¹ in which the valve spindle S
works the head g¹ of which forms the valve and this valve is held on its seating formed
at the end of the sleeve a¹ by the spring s². Fixed to this valve is the needle N or
its equivalent the other end of which passes through the small hole t¹ formed in the
end of the thimble or cup fixed in the end of the valve box and through which the oi!
is sprayed into the vaporiser V. The oil as it is forced by a pump from an oil tank
through the inlet B passes down the sleeve a¹ and as it passes out through the valve
and through the thimble or cup T to the vaporiser it lifts the valve from its seating
thereby keeping the needle N in constant motion by which means the outlet hole t¹
in the thimble or cup is kept free from carbon or other matter thus allowing the
oil to pass freely through to the vaporiser. It will be evident that instead of fixing
the needle to the valve for the purpose of keeping it in motion this may be
accomplished by other means so long as the needle is constantly agitated in the
hole for the purpose of keeping it free from carbon or other matter."

Having now particularly described and ascertained the nature of
invention and in what manner the same is to be performed we declare that what we

substantially as herein set forth and shewn upon the drawings.
Second: In valve boxes for oil engines fixing or mounting a needle N in connection
with the valve V or other moving part so that it reciprocates in the hole or outlet t¹
for the purpose of keeping the hole always clear and free substantially as herein set
forth.
