I, CHARLES EDWARDS AMOS, of the Grove, Southwark, in the. County of
Surrey, Engineer, do hereby declare the nature of the said Invention for
"AN IMPROVED ARRANGEMENT OF STEAM MACHINERY. FOR DRIVING ROTARY PUMPS,"...
to be as follows: -...
The object of this Invention is to render the artificial foundation constructed.
for the setting up of rotary pumps, available for carrying the weight of the
engines employed for driving the same. This I' effect by mounting one or
a pair of engines' upon, or attaching them to, the sides of the vertical pump
case, which may be recessed or otherwise shaped to afford a good bearing to
the cylinders. The piston rods of these engines I. connect to a horizontal
crank shaft which carries a-bevil wheel in gear with a pinion on the upright
spindle of the pump, and the valves of these engines I drive (as usual) by

page_text: excentrics on the crank shaft. By this Invention I am enabled to save the
expense of providing a separate foundation for the engines, which is a matter
of considerable importance when the pumping machinery is required to be
erected (as is most frequently the case) on marshy ground.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Edwards Amos in the Great Seal Patent Office on
the 4th May 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
EDWARDS AMOS, of the Grove, Southwark, in the County of Surrey, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of November, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Charles Edwards Amos, Her special license that I, the said Charles
Edwards Amos, my executors, administrators, and assigns, or such others as I,
the said Charles Edwards Amos, 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 "AN
IMPROVED ARRANGEMENT OF STEAM MACHINERY FOR DRIVING ROTARY PUMPS,"
upon the condition (amongst others) that I, the said Charles Edwards Amos,
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 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 Charles Edwards Amos, do hereby
declare the nature of my said Invention; and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Drawing hereunto annexed,
and to the letters and figures marked thereon (that is to say) :-
:-
The object of this Invention is to render the artificial foundation con-
structed for the setting up of rotary pumps available for carrying the weight

page_text: of the engines employed for driving the same. The manner in which I prefer
to effect this, is to mount one or a pair of engines upon the sides of-the
vertical pump case, which may be recessed or otherwise shaped, to afford a
good bearing to the cylinders, but where the pump is required to be sunk a
considerable depth below the ground surface, I propose to mount the engines
on the walls of the shaft in which the pump is sunk, instead of extending the
metal casing up to the ground surface. The piston rods of these engines I
connect to a horizontal crank shaft which carries a bevil wheel in gear with
a pinion on the upright spindle of the pump, and the valves of these engines I
drive (as usual) by excentrics on the crank shaft.
In the accompanying Drawing, Fig. 1 shews in side elevation, Fig. 2 in
front elevation (partly in section), and Fig. 3 in plan view, so much of my
arrangement of pumping, machinery as will serve to explain the nature and
mode of carrying out my Invention. a, a, is a case or tank of cast iron set in
brickwork, and communicating by pipes 6 with the water to be raised. In
the centre of this case or tank is mounted a vertical shaft c, which carries at
its lower end the centrifugal fan or wheel d for raising the water. This shaft
has its bearings in a central tube e, and in a cross beam of the engine framing
or standards f, f, above. The tank a is recessed at its upper part, at a*, for
the purpose of receiving and supporting the engines g, g, which are intended
to drive the centrifugal pump. The pistons and slide valves of these engines
are connected by the usual gear with a common crank shaft h, which has its
bearings in the standards f. f. Upon this shaft h is mounted the bevil wheel i,
which gears into the bevil wheel k on the shaft c, and thereby communicates
to that shaft the rapid rotary motion required to keep the pump in efficient
action.
By this Invention it will be understood that I am enabled to save the
expense of providing a separate foundation for the engines, which is a matter
of considerable importance, and particularly when the pumping machinery is
required to be erected (as is not unfrequently the case) on marshy ground.
Having now set forth the nature of my Invention of "An Improved Arrange-
ment of Steam Machinery for Driving Rotary Pumps," and explained the
manner of carrying the same into effect, I wish it to be understood that under
the above in part recited Letters Patent, I do not intend to claim any of the
parts, either of the steam engine or engines, or of the centrifugal pump, when
taken separately or in detail; but I claim the combination as described,
wherein the steam engines used for driving the centrifugal pump through the
intervention of wheel gearing are placed upon the pump case, or on the

page_text: masonry used as a substitute therefor, or continuation thereof, by which means
the cost of providing separate foundations for the engines and pump will be
avoided.
In witness whereof, I, the said Charles Edwards Amos, have hereunto
set my hand and seal, the Third day of May, in the year of our Lord
One thousand eight hundred and fifty-eight.
