IMPROVEMENTS. IN HYDROPULTS. AND HYDROSTATIC PUMPS
Year: 1865

page_text: LETTERS PATENT to James Webster, of Birmingham, in the County of
Warwick, Engineer, for the Invention of "IMPROVEMENTS. IN HYDROPULTS.
AND HYDROSTATIC PUMPS."
Sealed the 6th March 1866, and dated the 8th September 1865.
PROVISIONAL SPECIFICATION left by the said James Webster at the
Office of the Commissioners of Patents, with his Petition, on the 8th.
September 1865.
†, JAMES WEBSTER, of Birmingham, in the County of Warwick, Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
HYDROPULTS AND HYDROSTATIC PUMPS," to be as follows, that is to say:-
My improvements in hydropults consist in the employment of a single
barrel divided in mid-length into two parts, the lower receiving the pump
bucket, and the upper forming an air chamber; at the foot of the lower part
is a valve and seating immediately above the induction pipe, and at the lower
end of the upper part is another valve; these two parts are screwed together,
a perforated plate being secured in the upper end of the lower part; a tube'
passes through this plate to the top end of the upper part, in the cap of which
it is fixed, a stuffing box or gland being secured above it; a piston rod worked
by a handle passes through this tube and through the centre valve to the
bucket. A second tube is screwed to the cap of the barrel, and hangs within
the barrel to a depth of about one inch from the centre valve; to this tube the

page_text: jet or eduction pipe is screwed; it follows that by the action of the piston and
bucket water is raised through the lower part of the barrel into the upper
part or air chamber, whence by atmospheric pressure it is driven through
the second tube and ejected.
My improvements in hydrostatic pumps consist in the employment of a
cylinder with a convex top and concave bottom, with a small air pump
attached at one side, and on the opposite side an eduction pipe or.jet. At the
top_of_the_cylinder.is.fixed-a-valve-attached-to-a hollow copper ball, so that
on filling the cylinder with water to a given height the ball should rise and
close the valve; the air pump being then worked, air is compressed into the
space above the water, and by its expansion forces the water through the jet
in a continuous stream until the cylinder is empty; a stop-cock is attached
to the jet, so that the cylinder having been charged may remain for any length
of time, when by turning the stop-cock it may be used without further labor.
The cylinder is charged with water at the top through the valve.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Webster in the Great Seal Patent- Office on the 8th
March 1866,
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
WEBSTER, of Birmingham; in the County of Warwick, Engineer; send
greeting,
.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of September, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said James Webster, Her special license that I, the said James Webster, my
executors, administrators, and assigns, or such others as I, the said James.
Webster, my excoutors, administrators, and assigns, should at any time agree.
with, and no others, from time to time and at all times thereafter-during the
term therein expressed, should and lawfully, might niake, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN HYDROPULTS
AND HYDROSTATIC PUMPS," upon the condition (amongst others), that I, the
said James Webster, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said Invention,
and, in what manner the same was to be performed, and cause the same to

page_text: be filed in the Great Seal Patent Office within six calendar months next and.
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said James Webster, do hereby. declare the,
nature of my said Invention, and in what manner the same is to be. per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the Drawings hereunto, annexed, and to
the letters and figures marked thereon (that is to say):-
My improvements in'hydropults or apparatus for throwing water or other
fluids consist in the employment of. a single barrel divided in.mid-length into.
two parts, the lower receiving the pump bucket, and the upper forming an
air chamber.
N
The annexed Drawings represent vertical and transverse sections of the
apparatus. At the foot of the lower part of the barrel is a valve (a) and
seating (b), immediately above the induction pipe (c), a second valve (a¹)
being placed in the bucket (a), and at the lower end of the upper part (d) is
another valve (e); the two parts are screwed together, a perforated plate (f)
being secured in the upper end of the lower part; a' tube (9) passes through
this plate (f) to the top end of the upper part in the cap (h) of which it is
fixed,, a stufling box or gland (i) being secured above it. A piston rod (k),
worked by a handle (1), passes through this tube and through the centre
valve (e) to the bucket (x). A second tube (m) is screwed to the cap (h) of
the barrel, and hangs within the barrel to a depth of about one inch from the
centre valve (e); to this tube the jet or eduction pipe (o) is screwed ;
it follows that by the action of the piston and bucket and valve (a¹) water is
raised through the lower part of the barrel into the upper part or air
chamber, whence by atmospheric pressure it is driven through the second
tube and ejected.
My improvements in bydrostatic pumps consist in the employment of a
cylinder with a convex top and concave bottom, with a small air pump
attached at one side, and on the opposite side an eduction pipe or jet. At the
top of the cylinder is fixed a valve attached to a hollow copper ball, so that in
filling the cylinder with water to a given height the ball should rise and close
the valve; the air pump being then worked, air is compressed into the space
above the water, and by its expansion forces the water through the jet in a
continuous stream until the cylinder is empty; a stop-cock is attached to the
jet, so that the cylinder having been charged may remain for any length of
time, when by turning the stop-cock it may be used without further labour.
The cylinder is charged with water at the top through the valve.
Having thus described the nature of my said Invention, and in what

page_text: manner the same is to be performed, I claim, without limiting myself to
these precise details, the improvements in apparatus for throwing water or
other fluids substantially as herein more fully set forth and specified.
In witness whereof, I, the said James Webster, have hereunto set my
hand and seal, this Sixth day of March, in the year of our Lord One!
thousand eight hundred and sixty-six.
