AN IMPROVEMENT IN THE MANUFACTURE OF PUMPS
Year: 1855

page_text: LETTERS PATENT to Uriah Lane, of 46, Regency Square, Brighton, in
the County of Sussex, for the Invention of "AN IMPROVEMENT IN THE
MANUFACTURE OF PUMPS."
Sealed the 18th December 1855, and dated the 20th June 1855.
PROVISIONAL SPECIFICATION left by the said Uriah Lane at the Office
of the Commissioners of Patents, with his Petition, on the 20th June
1855,
I, URIAH LANE, of No. 46, Regency Square, Brighton, in the County of
Sussex, do hereby declare the nature of the said Invention for "AN IMPROVE-
MENT IN THE MANUFACTURE OF PUMPS " to be as follows, that is to say:-
My Invention consists in the manufacture of pumps without the piston or
plunger being fitted air-tight to the barrel, of the pump, whereby the friction
resulting from the construction of ordinary pumps is avoided, and the resist-
ance to lifting the plunger is principally confined to the weight of water raised,
and I-propose-to-carry out-this-idea-in-the-following-manner-:-I-take-two-
tubes of metal or other suitable material, of any convenient length, and of such
diameters or bores as will allow one to slide easily over the other; these tubes
are each open at one end, and a clack or other suitable valve is fixed at the
other end of each tube, which opens upwards. I then take another tube,
which I call the jacket or casing of the pump, and which is of sufficient.
diameter to include or surround the other two; this tube is considerably.
-

page_text: the longest, and is provided with a suction pipe and spout, as in an ordinary
pump. The larger of the two tubes first described is fitted to the pump
handle or crank by a rod or link, and the open end of the smaller tube
is fixed to the bottom of the jacket or casing over the suction pipe, and is
therefore in communication with the well or other reservoir of water; there is a
slight space between these tubes and the jacket. When the pump is to be used,
the jacket must be first filled with water, the smaller tube being within the
larger, and the valves at their upper ends near together. As the larger of these
tubes is raised, the air in the suction pipe and smaller tube will expand and
pass out through the valve at the top into the larger tube, and will escape
thence when the larger tube is plunged or brought down again, and so on,
until the pressure of the air on the surface of the water in the well sufficiently
exceeds that in the suction pipe and sinaller of these tubes to force the water
into them, as in the ordinary pump. It must be observed that this partial
vacuum is maintained by the water between the tubes and the jacket. In
some cases I may place the clack or valve at the bottom of the smaller of
these tubes instead of at the top, or dispence with it, the smaller of these
two internal tubes and use the jacket instead, by placing the clack or other
valve at the bottom over the suction pipe... This improved. puinp: will answer
all the purposes of an ordinary pump with a closely fitted piston.
SPECIFICATION in pursuance of the conditions of the Letters Patent; filed
by the said Uriah Lane in the Great Seal Patent Office on the 20th
December 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, URIAH
LANE, of 46, Regency Square, Brighton, in the County of Sussex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of June, in the year of our Lord One
thousand eight hundred and fifty-five, in the nineteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said Uriah Lane, Her special licence that I, the said Uriah. Lane, my.
executors, administrators, and assigns, or such others as I, the said Uriah
Lane, 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

page_text: vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "AN IMPROVEMENT IN THE MANUFAC-
TURE OF PUMPS," upon the condition (amongst others) that I, the said Uriah
Lane, by an instrument in writing under my hand and seal, should parti-
cularly 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 Uriah Lane, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to he particularly described and ascertained in and by the following
statement:-
My Invention consists in the manufacture of pumps without the piston or
plunger being fitted air-tight to the barrel of the pump, whereby the friction
resulting from the construction of the ordinary pumps is avoided, and the
resistance to lifting the plunger is principally confined to the weight of the
water raised; and I propose to carry out this idea in the following manner :-
I take two tubes of metal or other suitable material, of any convenient
length, and of such diameters or bores as will allow one to slide easily over the
other; these tubes are each open at one end, and a clack or other suitable
valve is fixed at the other end of each tube, which opens upwards. I then
take another tube, which I call the jacket or casing of the pump, and which is
of sufficient diameter to include or surround the other two; this tube is con-
siderably the longest, and is provided with a suction pipe and spout, as in an
ordinary pump. The larger of the two tubes first described is fitted to the
pump handle or crank by a rod or link, and the open end of the smaller tube is
fixed to the bottom of the jacket or casing over the suction pipe, and is there-
fore in communication with the well or other reservoir of water. When the
pump is to be used, the jacket must be first filled with water, and the smaller
tube being within the larger, and the valves at their upper ends near together;
on the larger of these tubes being raised, the air in the suction pipe and in the
smaller tube will expand and pass out through the valve at the top into the
larger_tube, and will_escape_thence_when_the_larger_tube.is_plunged.or_brought
down again, and so on, until the pressure of the air on the surface of the-water
in the well sufficiently exceeds that in the suction pipe and the smaller of
these tubes to force the water into them, as in the ordinary pump. It must be
observed that this partial vacuum is maintained by the water between the
tubes and in the jacket. In some cases I may place the clack or valve at the
bottom of the smaller of these tubes instead of at the top, or dispense with it,

page_text: the smaller of these two internal tubes, and use the jacket instead, by placing
the clack or other valve at the bottom over the suction pipe. This improved
pump will answer all the purposes of an ordinary pump with a closely fitted
piston.
I claim as my Invention the manufacture of pumps by an arrangement of
tubes without any other packing between them than that supplied by the
water or other liquid to be raised by the pump, as above described, and I do
not confine myself to the particular details herein-before mentioned, provided
the spirit and substance of my Invention be maintained.
In witness whereof, I, the said Uriah Lane, have hereunto set my hand
and seal, this Twentieth day of December, in the year of our Lord One
thousand eight hundred and fifty-five.
URIAH LANE. (L.S.)
