CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR FORCING AND RAISING WATER AND OTHER FLUIDS
Year: 1842

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ELSE, of Gray's Inn, in the County of Middlesex, Esquire, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Eighteenth day of August, in the sixth year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said Richard
Else, Her special licence, full power, sole privilege and authority, that I, the
said Richard Else, my exors, admors, and assigns, or such others as I, the said
Richard Else, my exors, admors, or assigns, should at any time agree with,
and no others, from time to time and at all times during the term of years
therein expressed, should and lawfully might make, use, exercise, and vend,
within England, Wales, and the Town of Berwick-upon-Tweed, my Invention
of "CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR FORCING AND RAISING
WATER AND OTHER FLUIDS;" in which said Letters Patent is contained a proviso,
that I, the said Richard Else, shall cause a particular description of the nature
of my said Invention, and in what manner the same is to be performed, to be
inrolled in Her said Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part recited Letters

page_text: sad by the same, reference being thereunto had, will more full
and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the sai
Richard Else, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following description thereof, reference being had to
the Drawing hereunto annexed, and to the figures and letters marked thereon
(that is to say):-
My Invention consists in a machine for forcing and raising water, as shewn
in the annexed Drawing. In the cylinder A, A, is a piston B, moving air-
tight (either a metalic piston accurately fitted, or a piston lined or stuffed, at
the option of the manufacturer). On the top of the piston rod is a weight C,
sufficiently heavy to keep the piston B always accurately in contact with the
surface of the water W in the cylinder. D is an air-tight stuffing-box, in
which the piston rod works; E, F, and G, are valves or stop-cocks, at the
option of the manufacturer, and according to the purposes to which the
machine is to be applied, opened and shut, according to circumstances, either
by hand or machinery. The other portions are sufficiently described in the
Drawing.
The mode of operation is this:-The screw plug or valve L being opened, the
valves E and G being shut, and the valve F being opened, the piston is drawn
up to the top of the cylinder and closely in contact with it, so as to exhaust all
the air; shut the screw plug or valve L, also the valves Z and F, open the
valves E and G; exhaust by means of the air pump all the air in the
cylinder and pipes; shut the valves E and F, open the valve G, also the valve Z.
The atmospheric pressure on surface of water in the reservoir will fill the
cylinder and pipes. Shut the valve G, open the valve F, the water will descend
and flow out, and as it flows out the piston B will descend, being charged with
a sufficient weight, immediately and closely in contact with the surface of the
water in the cylinder. When the piston has descended so low as the stops H, I,
shut the valve F, and open the valve E. Exhaust by the air pump the air
that will have entered and be left between the valve F and the piston, having
risen to the surface of the water below the piston on the valve F being shut.
The air being exhausted, shut the valve E and open the valve G, when the
water will by atmospheric pressure again fill the cylinder, raising also piston. 3
The succeeding operations will be a repetition of the foregoing. The machine
will have in connexion with it an air pump, reservoirs, and any machinery to
which it may be applicable, but which, being no new Invention, is not included.

page_text: in this Specification; the valves or stop-cocks will consequently be opened and
shut and the air pump be worked (as may be most advantageous by circum-
stances) by hand or machinery.
In witness whereof, I, the said Richard Else, have hereunto set my
hand and seal, this Thirteenth day of February, in the year of our
Lord One thousand eight hundred and forty-three.
