Improvements in Hydraulic Engines.
I WILLIAM SPEIGHT of 64 Rosebank Road Leeds in the County of York Engineer
do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide an apparatus to prevent bumping and
consequent strain and irregularity of motion at the end of each stroke of the piston in
hydraulic engines, and to give a smooth, steady and easy action to the engine thereby.
In order to effect this I employ an air vessel which may be made of any suitable
metal, and of any convenient shape and size. I place one of such air vessels at each
end of the cylinder in such a position that the same may be always between the
piston and the valve, so that as the valve is closing the exhaust port with the piston
coming to end of cylinder the air is compressed in the air vessel and forms a cushion
similar to that of a steam engine, consequently the engine works with a smooth and
regular action.

I WILLIAM SPRIGHT of 64 Rosebank Road Leeds in the County of York 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
The object of my invention is to provide an apparatus to prevent bumping and
consequent strain and irregularity of motion at the end of each stroke of the piston,
and to give a smooth, steady, and easy action to the engine thereby.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a longitudinal section, and Fig. 2 a plan looking at the top.
Now in order to effect the above end I employ an air-vessel A which may be made
of any suitable metal, and of any convenient shape and size.
I place one of such air vessels A at each end of the cylinder B by screwing the
same into such cylinder B, as shown at C, or by other means, applied in such a
position that the same may be always between the piston and the valve, so that as the
valve is closing the exhaust port with the piston coming to the end of cylinder B. the
air contained therein is compressed in the air vessel A, thus forming a cushion
similar to that of a steam engine, consequently the engine works with a smooth and
regular action.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed 1 declare that what I claim is :-
The arrangement of air vessel A applied to hydraulic engines, substantially as and
for purposes herein set forth.
