of Gloucester, Engineer, for the Invention of "IMPROVEMENTS IN AND
APPLICABLE TO PUMPS."

Sealed the 23rd January 1874, and dated the 22nd August 1873.
PROVISIONAL SPECIFICATION left by the said William Warren at the
Office of the Commissioners of Patents, with his Petition, on the
22nd August 1873.
I, WILLIAM WARREN, of Cheltenham, in the County of Gloucester,
5 Engineer, do hereby declare the nature of the said Invention for "Im.
PROVEMENTS IN AND APPLICABLE TO PUMPS," to be as follows, that is to
say:
This Invention relates to improvements in that class of pumps for
which Letters Patent were granted to me, and dated the Eighth day of
December 1866, No. 3242, in which the lift and foot valves are so
arranged as to allow of the contents of the pump barrel and feed pipe
being discharged when required to the source of supply, the object of my
present improvements being to render such pumps self-charging after
having been so emptied,

page_text: My improvements are applicable with special advantage to force
pumps.
To carry out my Invention I apply round the feed pipe of the pump
(at such distance below the surface of the ground as to be in no danger
of freezing) a cylindrical or other suitably shaped chamber or receiver.
The feed pipe from the pump barrel extends a short distance through
the top of this chamber. The top of the next length of feed pipe is
placed at a short distance below the bottom of the first length, so as to
leave a space between these pipes open to the said chamber. Some
small holes or other suitable openings are madein the feed pipe from or ]
_near the bottom of the said chamber, and the feed pipe below the bottom
of the said chamber is formed into or with a syphon
bend.
or shaped
By this arrangement, when the pump barrel and feed pipe are emptied
to prevent the water or other liquid being, frozen in cold weather, or for 1
any other purpose, a portion of the contents thereof will pass from the
feed pipe into the said chamber' through the space left between the two
pipes at the top thercof, but by reason of the smallness of the exit there-
from by the said holes or opening at the bottom thereof the said chamber
will remain partly charged after the water in the feed pipe has returned
to the source of supply. From the said chamber thus partly charged
the water will then dribble-into the feed pipe and fill the syphon or
shaped bend, so that when the pump is to be again used this liquid
will be raised into the pump barrel by the lifting of the bucket, and tho.
pump will become charged without it being necessary, as at present, to
pour water into the top of the pump to charge it after it has been
emptied.
In applying my improvements to the suction pipe of force pumps the
valves of the pump must be arranged by known means, so that the pump:
barrel may be emptied of its contents, which is not the case with force:
pumps as hitherto constructed.
My improvements are applicable to dumps at present constructed.

TO. ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WARREN, of Cheltenham, in the County of Gloucester, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of August, in the year.
of our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors, give.
and grant unto me, the said William Warren, Her special licence that
I, the said William Warren, my executors, administrators, and assigns,
or such others as I, the said William Warren, my executors, admin-
istrators, 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
AND APPLICABLE TO PUMPS," upon the condition (amongst others) that I, the
said William Warren, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, 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 William Warren, 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 hereto annexed
and to the figures and letters marked thereon, that is to say:-
This Invention relates to improvements in that class of pumps for which
Letters Patent were granted to me and dated the Eighth day of December,
One thousand eight hundred and sixty-six, No. 3242, in which the lift
the
and foot valves are so arranged as to allow of the contents of t
pump
barrel and feed pipe being discharged when required to the source of
'

page_text: supply, the object of my present improvements being to render such
pumps self-charging after having been so emptied.
My improvements are applicable with special advantage to force
pumps, the valves of which must be arranged to allow of the pump
barrel being emptied.
To carry out my Invention I apply round the feed or suction pipe of
the pump (at such distance below the surface of the ground as to be in
no danger of freezing) a cylindrical or other suitably shaped chamber or
cistern. The feed or the suction pipe from the pump barrel extends a
short distance through the top of this chamber. The top of the next
length of feed pipe is placed at a short distance below the bottom of the
first length, so as to leave a space between those pipes open to the said
chamber. Some small holes are made in the feed pipe near the bottom
of the said chamber, and the feed pipe below the said chamber is formed
into or with a syphon or shaped bend. Or the feed or suction pipe
may extend nearly to the bottom of the said chamber or cistern, and the
next length of pipe commence a short distance from the top of the said
chamber. In this case the said holes and syphon are not required. I
prefer this latter arrangement.
By this latter arrangement, when the pump barrel and feed or suction
pipe are emptied to prevent the water or other liquid being frozen in
cold weather, or for any other purpose, a portion of the contents thereof
will pass from the feed or the suction pipe into the said chamber, and
nearly fill the same, so that when the pump is to be again used this
liquid will be raised into the pump barrel by the lifting of the bucket or 2
of the plunger, and the pump will become charged without it being
necessary, as at present, to pour water into the top of the pump or other-
wise to charge it after it has been emptied.
In the first herein-before described arrangement the contents of the
pump barrel, instead of remaining in the said chamber, will dribble 8
through the said holes in the feed or suction pipe into the syphon, and
will remain there ready to recharge the pump when required.
My improvements are applicable to pumps at present constructed.
Having thus described the nature of my Invention I will proceed more
particularly to describe the same, and the best means I am acquainted 3
with for carrying it into effect by reference to the accompanying
Drawing.

page_text: Figure 1 is a section shewing the arrangement I prefer for carrying
out my Invention.
A is the lower part of a pump barrel, and B the feed pipe or the
suction pipe of the same, as the case may be. The valves of the pump
must be arranged as herein-before described to allow of the pump barrel
being discharged down the pipe.B. C is the cylindrical or other shaped
chamber, which I apply round the feed or suction pipe B, such pipe
extending nearly to the bottom of the said chamber or cistern. The
next length of pipe B' commences at a short distance from the top of
the chamber or cistern C, and passing through the bottom thereof
extends downwards to the source of supply. In this arrangement it will
be easily understood that if the contents of the pump barrel be dis-
charged, as herein-before described, the said contents will pass down the
pipe B, and out at the bottom thereof into the chamber C, and will
remain there, or so much thereof as can be contained therein, below the
level of the top of the pipe B². When it is required to recharge the
pump the liquid contained in this chamber can be raised into the pump
barrel by the mere lifting of the bucket or plunger, thus charging the
pump without it being necessary to take away any part or parts of the
pump, as has hitherto been necessary. In Figure 2 the feed or suction
pipe B from the pump barrel A. passes a short distance through the top
of the chamber C, the top of the next length B¹ being placed at a short
distance below the bottom of the first length B. d, d, are the holes in
the pipe B, and D' is the syphon. In this arrangement, when the
contents of the pump barrel are discharged, as herein-before described,
the said contents or a portion thereof will pass into the chamber C
through the space D between the two pipes B, B', and will then pass
through the holes d, d, down the pipe B' into the syphon D¹, and will
remain there ready to serve for recharging the pump when required in
a similar manner to that described in the first arrangement.
Having thus described my said Invention, and the best means I am

Secondly. The employment in combination with the said chamber or
cistern of a syphon, substantially in the manner herein-before described
and represented in Figure 2 of the accompanying Drawing.
In witness whereof, I, the said William Warren, have hereto set
my hand and seal, this Third day of March, in the year of our
Lord One thousand cight hundred and seventy-four.
