-A communication from abroad by Thomas Hansbrow, of the City and
County of Sacramento California United States of America.
Sealed the 4th July 1862 and dated the 4th April 1862.
PROVISIONAL SPECIFICATION left by the said William Edward Newton
at the Office of the Commissioners of Patents, with his Petition, on the
4th April 1862.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Civil Engineer, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN PUMPS FOR SHIPS' USE AND OTHER
PURPOSES," to be as follows:-
This Invention consists in the arrangement of inclined valves on inclined
seats in combination with a horizontal or other suitable pump cylinder, and
with a piston, to which a reciprocating motion is imparted by means of a
sliding plate operated by a three-armed oscillating lever, whereby a pump is
obtained which can be easily operated, and will throw a large stream of water,
and in which sand or other solid matter that may be drawn in by the pump
will be prevented from lodging on the inclined valves or seats, and obstructing
the operation of the pump.
The Invention consists also in the employment of hinged swinging bolts,
which are made to catch into slotted ears made on flanges that project from
the bottom of the air vessel over the ends of the valve chest, which is placed

page_text: on the upper side of the pump cylinder. By the above arrangement the air
vessel can readily be fastened and unfastened, and detached from the pump in
order to obtain access to the interior of the valve chest without much trouble
whenever desired. A suitable packing is of course provided for making an
air-tight joint between the lower flange of the air vessel and the upper edge
of the valve chest.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Edward Newton in the Great Seal Patent Office
on the 14th August 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the County
of Middlesex, Civil Engineer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of April, in the year of our
Lord One thousand eight hundred and sixty-two, in the twenty-fifth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said William Edward Newton, Her special license, that I, the
said William Edward Newton, my executors, admors, and assigns, or
such others as I, the said William Edward Newton, my executors, adminis-
trators, 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 FOR SHIPS' USE AND OTHER
PURPOSES," being a communication from abroad, upon the condition (amongst
others) that I, the said William Edward Newton, 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 is 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 William Edward Newton, 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, reference being had to the Drawing hereunto
annexed, and to the letters and figures marked thereon (that is to say) :-

a reciprocating motion is imparted by means of a sliding plate, operated by a
three-armed oscillating lever, as will be herein-after more fully described,
whereby a pump is obtained which can be easily operated, and will throw a
large stream of water, and in which sand or other solid matters that may be
drawn in by the pump will be prevented from lodging on the inclined valves
or seats, and obstructing the operation of the pump.
The Invention consists also in the employment of hinged swinging bolts,
which are made to catch into slotted ears made on flanges that project from
the bottom of the air vessel over the ends of the valve chest, which is placed
on the upper side of the pump cylinder. By the above improvements the air
vessel can readily be fastened and unfastened and detached from the pump in
order to obtain access to the interior of the valve chest without much trouble
whenever desired. A suitable packing is of course provided for making an
air-tight joint between the lower flange of the air vessel and the upper edge
of the valve chest.
same.

In the accompanying Drawing, Fig. 1 is an external elevation of the pump
drawn in perspective; and Fig. 2 is a longitudinal vertical section of the
The pump cylinder A is secured by means of a plate or bracket B to
a suitable board or standard. The plate B forms the bearing for the rock
shaft C, on which the three-armed lever D-is mounted. The two arms a, a,
of this lever extend up to about the middle of the cylinder A, and are secured
to their ends by means of pivots 6 to the levers or handles E. The inner ends
of these hand levers, when the same are brought into a horizontal position, as
shewn in Fig. 1, are connected by two bolts c, or in 'any other desirable
manner, and when not in use these bolts are withdrawn, and the hand-levers
assume the position shewn in Fig. 2 in dotted lines.. The middle arm d of the
lever D is connected by a pivot e with a slotted ear f (Fig. 2), projecting
from the lower surface of the sliding plate F; this plate F is connected by
means of two standards 9 with the piston rod G¹ and piston G, so that by
imparting an oscillating motion to the rock shaft C a reciprocating motion of
the piston G is produced. The water enters through the suction pipe H into
the valve chest I, which communicates with the interior of the cylinder through
channels h, h. The receiving valves i close down upon the inclined seats j, so
that a small pressure is sufficient to raise them, and on the return stroke of
the piston the water passes out through one of the discharge valves k, which
close the apertures leading from the valve chest to the air vessel J.

page_text: The air vessel is secured to the top of the valve chest by means of the
swinging bolts K, which are pivotted at their lower ends to lugs / projecting
from the ends of the valve chest. These bolts K swing into slots m in cars n
projecting from the bottom of the air vessel as clearly shewn in the Drawing.
Thus by turning down these bolts K the air vessel is released, and may then
be easily removed. The water rises in the air vessel, and is discharged
through the exit aperture or pipe M.
By arranging the inclined valves above the cylinder, any sand or other
solid matter that may be drawn in by the pump is prevented from lodging in
the valves or in their seats, and thus obstructing the operation of the pump.
Furthermore by this arrangement the valves are kept tight, so that the charge
of water necessary to operate the pump cannot escape. By the sliding plate
arrangement to work the piston the latter is not only operated but kept in a
straight line also with the axis of the cylinder.
This Invention is particularly intended for ship's pumps, but it may be used
with advantage as a fire engine, or as a pump for any other purpose.
Having now described this Invention of improvements in pumps for ships'
use and other purposes, and having explained the manner of carrying the
same into effect, as communicated to me by my foreign correspondent, I claim
as the Invention secured to me by Letters Patent, as aforesaid,-
First, the general arrangement of parts herein set forth. I claim par-
ticularly placing the valves i, with their seats in an inclined position, and
arranging them with the suction pipe H and the exit valves above the pump
cylinder. I further claim the mode of actuating the piston as shewn and
described.
Second, I claim the mode herein set forth of adapting and securing the
air vessel to the valve chest or pump cylinder for the purposes above
mentioned.
In witness whereof, I, the said William Edward Newton, have here-
unto set my hand and seal, the Thirteenth day of August, in the
year of our Lord One thousand eight hundred and sixty-two.
