the Commissioners of Patents, with his Petition, on the 28th October
1864.
I, GEORGE RYDILL, of Dewsbury, in the County of York, do hereby declare
the nature of the said Invention for "A NEW HYDRAULIC ENGINE AND PUMP
FOR OBTAINING A MOTIVE POWER, OR GIVING POWER TO HYDRAULIC ENGINES, OR
BALANCE ENGINES, OR PUMPS," to be as follows:-
This Invention is for the purpose of making a new bydraulic engine or
engines, and for making pumps for obtaining a new motive power, which is
applicable for a motive power on land and sea.
And my Invention consists in making a hollow cylinder or sphere of cast iron
or any other metals, and of any required strength or length, with an opening
in the bottom of the cylinder or sphere, and one in the top of cylinder or sphere
to admit of a piston rod of equal diameter passing through the top and bottom
of cylinder or sphere, with stuffing boxes at each end of the said cylinder or
sphere, according to requirements, on to which piston rod I attach a weighted
piston or pistons, or plunger or plungers made of iron, lead, brass, copper, or
any other metal or mixture of metals, or stones or flint stones, or to coat or
cover the said weighted piston or plunger with any metal or material what-
soever to prevent penetration of water or any other liquid or fluid into the
weighted piston or plunger working inside the cylinder or sphere, which
piston or plunger I make to any required shape or form; I then charge the
cylinder or cylinders, or sphere or spheres with water or any other liquid or

page_text: fluid, and according to the weight or weights of piston or plunger within the
cylinder or sphere I bring in contact with the water, liquid, or fluid in the
cylinder or sphere an hydraulic ram, force pump, plunge pump, lever, or
screw in order to give any required pressure to or upon the water, or liquid,
or fluid in the cylinder or sphere, so that a pressure of the same specific
gravity may be given to the water, liquid, or fluid inside the cylinder as that
of the body of the weighted piston or plunger, which causes the weighted
piston or plunger inside the cylinder or sphere to be moved up or down with
the application of a very small force. This method of cylinder or sphere, and
piston or plunger, as described, with piston rod working through the top and
bottom of cylinder or sphere is easily attached to any engine, beam, crank, or
pump made to any required form, say, one cylinder or sphere to be fixed at
each end of or under the engine, beam, or crank, and made to move as with
steam, the pressure being given by the motion of the engine working a
reserve hydraulic or force pump, alternately shutting off the pressure of one
cylinder or sphere, and throwing the pressure on to the other cylinder or
sphere; or I attach the same kind of cylinder or sphere, and weighted piston
or plunger, as before described, to work an engine and to work a pump for
the purpose of lifting or forcing water, which pumping engine is easily made
to supply and work itself by the pressure given from a small supply of water
or any other liquid, and the water so pumped or forced from low ground is
easily applied as a motive power,
