Year: 1857

page_text: LETTERS PATENT to Saul Hart, of 33, Portland Street, Liverpool, for
the Invention of "IMPROVEMENTS IN APPARATUS FOR RAISING AND FORCING....
WATER."
Sealed the 21st July 1857, and dated the 4th February 1857..
PROVISIONAL SPECIFICATION left by the said Saul Hart at the Office
of the Commissioners of Patents, with his Petition, on the 4th February
1857.
I, SAUL HART, of 33, Portland Street, Liverpool, do hereby declare the
nature of the Invention for "IMPROVEMENTS IN APPARATUS FOR RAISING AND
FORCING WATER," to be as follows:-
This Invention has for its object improvements in apparatus for raising and
forcing water. For these purposes a cylinder or vessel is fixed with its lower
end in the water to be raised. This cylinder or vessel has an opening into it
at the bottom for the passage of water through it, and another opening near.
the top for the rising pipe which conveys the water to the height desired. The
top of the cylinder or vessel is covered, and has a stuffing box formed on the
cover. Within the fixed cylinder or vessel is an inner cylinder, the axis of
which passes through the stuffing box in the cover of the fixed vessel.. The
lower end of the axis of the inner cylinder rests on and turns in a suitable
step or bearing, and the lower end of this cylinder is closed, excepting where

page_text: it comes over the opening into the fixed cylinder, where there is a corre-
sponding opening into the inner, cylinder, and the inner and outer cylinders
around the openings are in contact with each other by a ground joint. The
interior of the inner cylinder is formed with a, hollow screw or spiral hollow
channel, up which the water rises when the inner cylinder is caused to rotate,
and the water so raised passes out at the upper part of the inner cylinder into
the outer cylinder, and thence up the rising pipe to the height it is to be raised,
and the water enters this hollow screw or spiral channel by one or more
ports or passages formed with inclined sides. The axis of the inner cylinder
receives rotatory motion from any suitable power, by bevilled whicels or other
means.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Saul Hart in the Great Seal Patent Office on the 3rd
August 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAUL
HART, of 33, Portland Street, Liverpool, send grecting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of February, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Saul Hart, Her special licence that I, the said Saul Hart, my execu-
tors, administrators, and assigns, or such others as I, the said Saul Hart, my
executors, 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 make, 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 APPARATUS FOR RAISING
AND FORCING WATER," upon the condition (amongst others) that I, the said
Saul Hart, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, 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 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 Saul Hart, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-

page_text: formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
This Invention has for its object improvements in apparatus for raising and
forcing water. For these purposes, a cylinder or vessel is fixed with its lower
end in the water to be raised. This cylinder or vessel has an opening into it
at the bottom for the passage of water through it, and another opening
near the top for the rising pipe, which conveys the water to the height desired.
The top of the cylinder or vessel is covered, and has a stuffing box formed on
the cover. Within the fixed cylinder or vessel is an inner cylinder, the axis
of which passes through the stuffing box in the cover of the fixed vessel. The
lower end of the axis of the inner cylinder rests on and turns in a suitable
step or bearing, and the lower end of this cylinder is closed, excepting where
it comes over the opening into the fixed cylinder, where there is a corre-
sponding opening into the inner cylinder, and the inner and outer cylinders.
around the openings are in contact with each other by a ground joint. The
interior of the inner cylinder is formed with a hollow screw or spiral hollow
channel, up which the water rises when the inner cylinder is caused to rotate.
and the water so raised passes out at the upper part of the inner cylinder
into the outer cylinder, and thence up the rising pipe to the height it is to be
raised, and the water enters this hollow screw or spiral channel by one or more.
ports or passages formed with inclined sides. The axis of the inner cylinder
receives rotatory motion from any suitable power, by bevelled wheels or other
means.
:
Having thus stated the nature of my Invention, I will proceed more fully
to describe the manner of performing the same:-
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a side clevation of lapparatus (constructed and combined
according to my Invention; Figure 2 shews a plan thereof; Figure 3 shew's
a vertical section thereof; Figure 4 shews a horizontal section thereof; and
Figure 5 shews a section of the rotating cylinder taken near the bottom.
thereof, and the parts are seen as if the observer were below and looking
upwards. a, a, is the rotating cylinder; a' is the opening at bottom by which
the water enters into the cylinder a, and the water is prevented entering. into
the outer case or cylinder 6 by reason of the joint or ground surfaces of the
opening a', which are in contact with raised surfaces b' formed on the interior
of the outer case or cylinder b. The water on rising into the cylinder a is
caused to ascend through the spiral channel a, a, formed therein, into which
there are two openings, as shewn by Figure 5, and the water escapes from the

page_text: .
cylinder a into the outer casing or cylinder b by the outlet passage a³ at the
upper part of the spiral passage. The cylinder a is to receive rotatory motion
in any convenient manner. In the arrangement shewn, c is a vertical axis or
shaft, to which the cylinder a is fixed, and it is supported at its lower end by a
step or bearing d. The upper end of the axis or shaft passes through a
stuffing box e, formed in the cover of the outer case or cylinder 6. On the
outer end of the shaft or axis c is a bevil cog wheel, which is driven by a bevil
cog wheelf on the axis g, which receives motion from the shaft by the cog
wheel and pinion i,j. The shaft h receives motion by cranked handles k, k,
by hand, or the same may be actuated by steam or other power. is a fly-
wheel on the shaft h. The water passes out from the case 6 by the outlet m,
which is raised to the height to which it is desired to deliver the water; or the
water may be delivered directly or at a low level from the case b.

Having thus stated the nature of my said Invention, and the manner of
performing the same, I would have it understood that I do not confine
myself to the details, nor do I claim
any of the mechanical parts separately;
but what I claim is the combination of apparatus herein described.
In witness whereof, I, the said Saul Hart, have hereunto set my hand
and seal, this Twenty-ninth day of July, in the year of our Lord One
thousand eight hundred and fifty-seven.
Witness,
EMANUEL HART,
of Liverpool, 29 July, 1857.
