IMPROVEMENTS IN SUBMERGED FORCE PUMPS
Year: 1872

page_text: COMPLETE SPECIFICATION filed by the said Andrew Jackson Reynolds
at the Office of the Commissioners of Patents, with his Petition
and Declaration, on the 4th November 1872, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, Í, ANDREW
JACKSON REYNOLDS, Civil and Mechanical Engineer, of White Plains,
New York, United States of America, now of 449, Strand, Charing
Cross, London, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
SUBMERGED 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 I am the
true and first Inventor thereof.
NOW KNOW YE, that I, the said Andrew Jackson Reynolds, 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 forming a
part of this Specification.

page_text: The nature of my Invention relates as herein-after explained to a
pump which forces water or other liquids to a considerable distance.
And my said Invention consists in the peculiar construction of the same
(exclusively of metal without the use of packing, which is clearly
illustrated in the accompanying Drawing, by the aid of which I will
now proceed to fully describe its operation.
Like letters indicate the same parts throughout the Drawing.
The discharge pipe A and hollow piston A¹ is immersed in the well B,
and secured there by bolts a to the timber frame b. The hollow piston
and discharge pipe are preferably cast in one piece of iron or any other
suitable metal. The cylinder C is made of metal, and provided at the
bottom with two valves c', c³, and a valve c³ is also provided in the piston
itself; these connect by the passages with the hollow piston A¹ and
discharge pipe A.
The working gear of this pump consists of a lever d whose fulcrum is.
at d', operating a bell crank d; this bell crank is forked at one end and
embraces the cross head d. In this cross head tho--set screws d' are
tapped through and are adjusted to the connecting rod e, and to the
working gear of the cylinder, and furnish a bearing in which the cross
head works. The connecting rod e is provided with a set screw e¹,
whereby it is adjusted to the cross head of the bell crank d³, its lower
extremity es being connected to the cylinder C.
When the lever is worked on the down stroke the water rises in the
chamber and fills the upper part of the cylinder C through the
valve opening at the same time fills the bottom of the cylinder,
and the contents of the cylinder are compelled on the upstroke of the
lever d to open the valve and close the valve c³, c³, and to escape
through the channel c* into the discharge pipe A in the manner shown
by the arrows. As the cylinder is raised by the lever d the valve c*

page_text: opens, closing the valve c¹, and thus admits water into the top of the
cylinder C by the passage k, and through the channel into the
discharge pipe A, and is carried up through the pipe to the vessel placed
there to receive it.
I prefer to have an opening h¹ in the side of the piston, so that I may
admit of the introduction of the valve c³, and a pin h² projects downward
from the channel h, thus maintaining the same in its seat.
In the first modification of my said Invention I fix the cylinder C to
the timber frame 6 by bolts as before described. The hollow piston and
rod A' are preferably cast in one piece. A valve c¹ is provided in the
bottom of the cylinder C. A ball valve c³ of vulcanized india-rubber is
provided at the bottom of the piston which is inserted through a tube
and is self-adjusting to its seat and requires no fitting. At the top of
the cylinder I provide a ball valve c³ for the purpose of preventing the
return of the water on the upstroke of the piston; at the downstroke of
the piston this valve opens and admits water into the upper part of the
cylinder, and to the discharge pipe.
The working gear is the same as fully described above.
When the lever d is worked on the upstroke the water rises into the
cylinder through the valve c¹. Upon the downstroke of the piston A¹
the contents of the cylinder are compelled to pass through the valve c³,
and escape through the hollow piston and discharge pipe as shown by
the arrows, and at the same time closes the valve c¹ at the bottom of the
cylinder, and opens the ball valve c³ at the top of the same, whereby a
continuous supply is maintained.
In my second modification I prefer to use the whole of the valves of
vulcanized india-rubber, being. self-adjusting and very effective. The
operations of these valves will be the same as already described.
In my third modification I provide and use in connection with the
bell crank and lever a pitman g which I attach to the connecting rod e,
or I may attach-the same to the hollow discharge pipe A.
Having thus fully described my said Invention, and the manner of
performing the same, I wish it understood that I claim, -
First. The hollow piston and discharge pipe containing the double-
action disc valve c* and opening h¹ for inserting the said valve within

page_text: the said piston, the whole being constructed and operating in connection
with a double-acting pump cylinder, substantially as set forth.
Second. The hollow piston containing the ball valve within the said
piston, and operating in connection with a double-acting pump cylinder,
substantially as set forth.
Third. The cylinder C provided with two ball valves in combination
with the water passages, all arranged and operating in connection with
a double-action hollow discharging piston, substantially as and for the
purpose set forth.
Fourth. The arrangement of the bolts d* serving the twofold purpose
of pivots and set screws; the cross head d³, bell crank d², lever d, and
pedestal do, the whole being combined with and serving to operate a
water discharging piston and pump cylinder, in the manner and for the
purpose set forth.
Fifth. The pitman 9 in combination with the lever d and hollow
piston, in the manner and for the purpose set forth.
In witness whereof, I, the said Andrew Jackson Reynolds, have
hereunto set my hand and seal, this Twenty-fourth day of
October, in the year of our Lord One thousand eight hundred
and seventy-two.
