IMPROVEMENTS IN PUMPS
Year: 1853

page_text: LETTERS PATENT to Thomas Adamson and William Adamson, of
Sunderland, in the County of Durham, for the Invention of
"IMPROVEMENTS IN PUMPS."
Sealed the 17th December 1853, and dated the 18th June 1853.
PROVISIONAL SPECIFICATION left by the said Thomas Adamson
and William Adamson at the Office of the Commissioners of
Patents, with their Petition, on the 18th June 1853.
We, THOMAS ADAMSON and WILLIAM ADAMSON, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN PUMPS " to be
as follows:-
This Invention consists, firstly, in certain mechanical arrangements
and combinations of parts for effecting a continuous lift and flow of
water in pumps. Secondly, in the use and application of glass in
and for the construction of the barrel thereof. The nature of this
Invention will, however, be better understood by reference to the
annexed Drawing, and to the numeral figures and letters of refer-
ence marked thereon, as follows:-

page_text: DESCRIPTION OF THE DRAWING.
A, A, marks the barrel of the pump, which is of glass, the same
being formed with a flange B, for connecting it to an external iron
casing or casting B', to which are connected several lengths of suction
pipe extending to the water to be raised, as ordinarily practised. C, D,
are pistons fitting within the glass barrel A, the interior of which
should be formed as nearly as possible cylindrical. The piston C, has
a rod c, attached thereto, which passes and works air-tight through
the upper piston D, and said rod is formed with a joint for connecting
it to a three throw crank E, E', so as to impart reciprocating motio
to the piston C, the piston D, being actuated by side rods c, the
lower ends of said rods being attached to a socket d, affixed to the
piston D, and the upper ends to cranks E', E', from which extends the
shaft G, the same being mounted in suitable bearings in the standards
II, II. I, I, are fly wheels fixed upon the shaft G, for carrying the
cranks E, E', beyond the null points. Thus it will be seen that by
imparting motion to the shaft G, the pistons C, D, will be continually
in action, the one ascending whilst the other is descending, thereby
effecting a continuous lift and flow of water.
ADDITION TO PROVISIONAL SPECIFICATION.
We, THOMAS ADAMSON and WILLIAM ADAMSON, of Sunderland, in
the County of Durham, do hereby declare the nature of our Inven-
tion for IMPROVEMENTS IN PUMPS " to be as follows:-
This Invention consists in an improved mode of imparting motion to
the buckets or "spear boxes" of lift pumps by the use and employment
of a three throw crank suitably connected for that purpose, and, further,
in the use and application of glass in combination with metal in the
construction of the barrels of lift pumps.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Adamson and William Adamson in the
Great Seal Patent Office, on the 17th December 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we,
THOMAS ADAMSON and WILLIAM ADAMSON, of Sunderland, in the County
of Durham, send greeting.
year
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of June, in the
of our Lord One thousand eight hundred and fifty-three, in the sixteenth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said Thomas Adamson and William Adamson, Her
special license that we, the said Thomas Adamson and William Adam-
son, our executors, administrators, and assigns, or such others as we,
the said Thomas Adamson and William Adamson, our executors, ad-
ministrators, 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 PUMPS,"
upon the condition (amongst others) that we, the said Thomas Adam-
son and William Adamson, by an instrument in writing under our
hands and seals, or under the hand and seal of one of us, 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 Oflice within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Adamson, on behalf of
myself and the said Thomas Adamson, do hereby declare the nature of
the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following
statement thereof, that is to say:
Our Invention consists, firstly, in an improved mode of imparting
motion to the buckets or what are technically termed "spear boxes"
of lift pumps, by the use and employment of a three throw crank or

page_text: cranked shaft suitably connected for that purpose; and, secondly, in the
use and employment of glass in combination with metal in the construc-
tion of the barrels of lift pumps, for the purpose of obviating the objec-
tion attending the corrosion of the barrel when formed of metal, as
hitherto practised in the construction of pumps. And an important
feature in our said Invention consists in so connecting the before-men-
tioned crank with the spear boxes as that the action thereof is direct.
In order to explain our said Invention as completely as possible we
now proceed to describe the best means we are acquainted with for
carrying our said Invention into practical effect, reference being had to
the illustrative Drawing hereunto annexed, and to the numeral figures
and letters of reference marked thereon respectively, as follows:
*
DESCRIPTION OF THE DRAWING.
Figure 1, exhibits a transverse and vertical section of a pump barrel
shewing the mode of connecting the crank shaft with the buckels or
spear" boxes. Figure 2, is a detached portion herein-after referred to.
At each of these Figures we employ similar letters of reference to denote
corresponding parts. A, A, marks the inner portion of the barrel of
the pump, which is of glass cemented into a casting B, suitably
formed to receive it, and to which several lengths of suction pipe are
connected, extending to the water to be raised, as ordinarily practised in
the construction of pumps. C, D, are buckets or spear boxes of the
ordinary construction, fitting and working air-tight in the glass
barrel A, the interior of which should be formed as nearly as possible
cylindrical. The spear box C, has a rod c, attached thereto, which
works air-tight through the upper spear box D; the rod c, is formed
with a joint at c, and the upper end of said rod is connected to the
middle cranked part E, of the shaft G, the cranked parts E', E¹, being
employed for connecting the upper spear box D, with the shaft by
means of side rods e, e, the lower ends thereof being connected to the
part d, of the spear box D, by pins or studs 1, 1, fixed to or formed
upon such said part. H, H, are fly wheels, and I, I, handles fixed
'upon the shaft G, which is supported by standards H', to which bear-
ings or brasses are affixed, in which said shaft revolves, and thereby

page_text: imparts reciprocating motion to the buckets or spear boxes C, D,
through the agency of the bandles I, I, and rods c, and e.
Having now described the nature of our said Invention of improve-
ments in pumps, and in what manner the same is to be and may be
performed, we desire it to be distinctly understood that we do not claim
the exclusive use of any of the separate parts above mentioned and re-
ferred to, except in so far as the same may be employed in combination
and for the purposes of our said Invention, which we hereby declare to
consist in, and we claim the use and employment of, a three throw
crank or cranked shaft, and the connecting thereof direct with the
buckets or spear boxes" of pumps, for the purpose of imparting re-
ciprocating motion thereto, as herein-before particularly described, set
forth, and represented by the illustrative Drawing hereunto annexed.
In witness whereof, I, the said William Adamson, have here-
unto set my hand and seal, this Fourteenth day of December,
in the year of our Lord One thousand eight hundred and fifty-
three.
WILLIAM ADAMSON. (L.S.)
