Office," Southampton Buildings, London, for the Invention of
"IMPROVEMENTS IN COMBINED LIFTING AND FORCE PUMPS."-A commu-
nication from abroad by Isaac H. Gustin, of Middletown, Indiana,
United States of America.
Sealed the 15th November 1870, and dated the 4th October 1870.
COMPLETE SPECIFICATION filed by the said George Haseltine at
the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 4th October 1870, pursuant to the 9th Section
of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," Southampton Build-
ings, London, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
COMBINED LIFTING AND FORCE PUMPS," and have petitioned Her Majesty to
grant unto me, my executors, administrators, and assigns, Her Royal
Letters Patent for the same, and have made solemn Declaration that it

page_text: has been communicated to me from abroad by Isaac H. Gustin, of
Middletown, Indiana, United States of America.
NOW KNOW YE, that I, the said George Haseltine, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed, in and by the following
statement, reference being had to the accompanying Drawing, making
a part of this Specification:-
My Invention relates to the construction of an ordinary lifting pump
in such a manner that it may be converted into a force pump at will,
and the said Invention consists in dividing the stock of the pump into
an upper and lower chamber by means of a water-tight core, and
providing the said core with an opening which unites the two chambers
and a suspended valve that when closed with the core separates the
two chambers so as to cut off communication with the upper chamber
and put the lower one in communication with an auxilliary air chamber,
from this air chamber the water is expelled by the force of the air
therein against the constant supply of the water from the lifting pump,
so that the latter may be converted into a forcing hydrant and used with
a hose in case of fire or for other purposes.
DESCRIPTION OF THE DRAWING.
Figure 1 is an elevation of a pump embracing my improvements;
Figure 2 is a vertical section showing the parts arranged as for an
ordinary lifting pump; Figure 3 is a similar section showing the
several parts arranged as for a force pump; Figure 4 is a top view of
the said pump.
A represents the pump stock fitted with a supporting plug B at its
lower end through openings in which water enters, and is held therein
by a valve C at its top. It is divided near the middle of its length into
an upper and a lower chamber E and D, and is provided with the usual
valved sucker G, bandle H, and egress spout I. The connecting rod J
of the valve sucker passes through a central opening in the division plug P,
and is packed in any suitable manner. The two chambers of the pump
thus formed communicates with each other through an opening a in the
division plug P, but may be separated to cut off this communication by
means of a suspended valve K, the connecting rod Q of which passes
through the opening a in the plug P, and up through an opening in

page_text: the cap R to which it is held. It is kept from falling too far by a pin c
and locked when raised to close the opening in the division plug P by
a latch d pivoted to the cap R, as shown in Figure 3. The suspended
valve K is made conical and its position is sufficiently far below the
division plug P to clear the opening, but when drawn up by its rod Q
it is made to fit the correspondingly shaped mouth of the communicating
opening a so as to seal it. When this valve is open the sucker lifts the
water and discharges it through the spout I, but when closed the lower
chamber E is put into communication with an auxilliary air chamber L,
arranged on the outside of the pump stock A by means of a pipe M,
communicating with the lower end of the said air chamber and the
upper end of the lower pump chamber E. This air chamber is located
near the top of the pump stock and secured thereto by any suitable
means. It is provided with an ingress valve fat its lower end, and a
stop-cock N and an egress nozzle O, to which a hose may be attached when
desired. The water is pumped into this chamber through the connecting
pipe M. and valvef; to compress the air therein, and when the faucet N
is open the water is forced out through the hose and will be thrown a
distance equal to the pressure of the air in the chamber L aided by the
constantly supplied steam from the lower chamber E. The division
plug P is fitted tightly upon a seat within the chamber of the pump,
and is secured by a screw o so that it may be removed if desirable.
Having thus fully described the said Invention, as communicated
to me by my foreign correspondent, I wish it understood that I
claim,―
First. The division plug P with its water passage, in combination
with the upper and lower chambers D, E, of the pump and the
suspended valve K, constructed and operating substantially as herein
described.
Second. The auxilliary air chamber L arranged on the outside of the
pump and communicating with the lower water chamber E thereof, in
the manner and for the purpose herein described.
Third. The sealing valve K of the lower water chamber, united
to and operated by means of a connecting rod Q held up when closed
by the latch d, and supported when open in the manner and for the
purpose herein described.
Fourth. The means herein described and shewn for converting an
ordinary lifting pump into a forcing pump or hydrant.

page_text: Fifth. The combination in a lifting pump of the division plug P, the
upper and lower water chambers D, E, the communicating opening a,
the suspended valve K, with its opening and closing connecting rod Q,
the auxilliary air and water chamber L, with its connecting pipe M, and
nozzle and stop-cock N, the whole constructed, arranged, and operating
substantially as herein described.
In witness whereof, I, the said George Haseltine, have hereunto
set my hand and seal, this Fourth day of October, in the year
of our Lord One thousand eight hundred and seventy.
Witness,
