We. WILLIAM JAMES SLUCE, of Bethnal Green Road, in the County
of Middlesex, Engineer, GEORGE BENJAMIN MATHER, of Derby, in the
County of Derby, Gent", & PHILLIP WOOD, of Stratford, in the County
of Essex, Gent", do hereby declare the nature of the said Invention for
"A NEW APPARATUS FOR RAISING AND FORCING WATER OR OTHER FLUIDS"
to be as follows:-
Our Invention consists of "An, Apparatus for Raising and Forcing
Water or other Fluids," in which apparatus, we have a cylinder or
chamber connected with a boiler at the top, and with a well or tank at
the bottom, by means of pipes which are alternately opened and closed
by the action of slide valves provided for that purpose; by the action of
these valves steam & water are alternately admitted into the said cylinder
or chamber, in which there is a piston or lid which rises and falls with

page_text: the water. The cylinder or chamber being filled with steam, the valve
on the pipe connecting it with the boiler is closed, and the valve on the
pipe connecting it with the well or tank is opened, when as the steam
is condensed the pressure of the air upon the surface of the water in
the well or tank causes the water to ascend, and make good the space
or vacuum occasioned by the condensation of the steam until the
cylinder or chamber is filled with water, when the valve on the pipe com-
municating with the well or tank is closed, and another valve also at the
bottom of the cylinder on à pipe opening into a reservoir into which
the water is discharged is opened; at the same time the valve on the
steam pipe being also opened, the steam is again admitted at the top of
the cylinder, the water is discharged, and the space left thereby is again
filled with steam, which again condenses, and the operation above
mentioned is repeated; the motion of the water governs the action of
the valves, which are moved by gearing attached to the apparatus.
Thus far we have described the action of the apparatus," "when the
altitude or height to which the water is raised, does not exceed the
height of a column of water that the pressure of the atniosphere will
support in vacuo, or from 30 to 32 feet; beyond which height or
against: pressure, as in the case of keeping up the supply to a steam
engine boiler, the action of the apparatus is as follows (that is to say):
First, when it is required to raise the water more than 30 to 32 feet,
then, instead of the water being discharged into a reservoir on a level
with the bottom of the cylinder or chamber, it is forced up a rising
main to the required altitude by the pressure of the steam on the
pistón or lid before mentioned; or, if the altitude is not too great,
(for instance, more than 60 feet,) then the water may be raised by
placing two or more apparatuses one above the other. Secondly, when
it is required to force the water against pressure, as in the case of
keeping up a supply in a steam engine boiler, then the action of the
apparatus is reversed, and the steam is admitted at the bottom of the
cylinder or chamber, and the water from the cistern in stationary
engines, and from the tank or tender in locomotive engines, at the top
of the sad cylinder or chamber; the lead of the slide valves is increased,
so that before the steam port is opened the water port is closed. The

page_text: cylinder in this case requires no piston or lid, but the bottom is inclined
so as to have a fall towards the steam port, which is placed below it;
and as the steam is condensed, and the water admitted from the cistern
or tender, as the case may be, at the top, it falls and enters the boiler as
often as the steam port is opened. The slides valves in this case may
be worked by a motion taken from the engine itself.
