PROVISIONAL SPECIFICATION.
Improvements in Pumps.
I, GEORGE SAVIN, of Thanet Iron Works, King Street, Margate, Blacksmith, etc.,
do hereby declare the nature of this invention to be as follows:-
My Invention relates to the general construction and arrangement of hand pumps
suitable for use on ships, canals, farms, sewage, cesspool, and other works, or for other
purposes for which such pumps may be required; and the invention has for its object
to provide a readily portable hand pump of the three-throw type which may be easily
transported from place to place and quickly applied to the required purpose
The pump is, as above mentioned, of the three-throw type and comprises three
vertical pump barrels communicating at bottom with a common suction chamber fitted
with perpendicular or horizontal suction connections, according to the circumstances
of the particular case, and opening at top into a common delivery chamber provided
with a spout or launder for carrying-off the liquid pumped. The three pump barrels.
with the suction and delivery chambers, are mounted in a frame composed of a pair
of A-standards braced together and adapted to be temporarily fixed in the required
position for use and the pump buckets are worked from a three throw crank shatt
through stirrup-shaped connecting rods jointed to the bucket rods which slide in cross-
guides at the top of the delivery chamber. The crank shaft is mounted at the upper
part of the frame and provided with winch-handles and fly wheel.

COMPLETE SPECIFICATION.
Improvements in Pumps.
I, GEORGE SAVIN of Thanet Iron Works, King Street, Margate, Blacksmith and
Ironmonger, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
My Invention relates to the general construction and arrangement of hand pumps
suitable for use on ships, canals, farms, sewage, cesspool and other works, or for other
purposes for which such pumps may be required, and the invention has for its object
to provide a readily portable hand pump which may be easily transported from place
to place and quickly applied to the required purpose.
The Invention is illustrated in the accompanying drawings forming part of this
specification, in which figure 1 is a longitudinal, and figure 2 a transverse vertical,
section. The same letters of reference indicate like parts in both figures.
The pump is, preferably, of the three-throw type and comprises, in the example
illustrated, three vertical pump barrels A communicating at bottom with a common
suction chamber B fitted with suction connections C at the side and bottom for use
according to the circumstances of the particular case. The three barrels A open at
top into a common delivery chamber D provided with a spout or launder and the
three pump barrels, with the suction and delivery chambers, are mounted in a frame
composed of a pair of A-shaped standards E braced together by cross-bar- F and
forming a rigid structure adapted to be readily transported from place to place as may
he required, ana to be fixed in any required position for use. The buckets G of the
three pump barrels are worked from a three-throw crank shaft H mounted in
bearings at the apexes of the A-shaped standards, the cranks being coupled to the
ונ...D

page_text: buckets G through stirrup-shaped connecting rods I jointed at i to the respective
bucket rods K. The rods K slide in guides Lin cross-bars fixed on top of the delivery
chamber D. The buckets are provided with the usual valves g and the barrels have
foot valves at a through which communication with the suction chamber is controlled.
Although I have described the pump as provided with three barrels, I do not limit
myself to that number as I may use two, three, or more pumps operated from a corre-
sponding number of cranks.
.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same 18 to be performed, I declare that what 1
claim 18;
The herein described construction of portable hand pump, substantially as specified.
