IMPROVEMENTS IN FORCE PHIMPS
Year: 1866

page_text: LETTERS PATENT to Thomas Joseph Reader, of 17 and 20, Cullum
Street, Fenchurch Street, in the City of London, for the Invention of
"IMPROVEMENTS IN FORCE PHIMPS
Sealed the 14th September 1866, and dated the 16th March 1866.
PROVISIONAL SPECIFICATION left by the said Thomas Joseph Reader
at the Office of the Commissioners of Patents, with his Petition, on
the 16th March 1866.
I, THOMAS JOSEPH READER, of 17' and 20, Cullum Street, Fenchurch
Street, in the City of London, do hereby declare the nature of the said'
Invention for "IMPROVEMENTS IN FORCE Pumps," to be as follows:-
This Invention has for its object improvements in force pumps. In
constructing a double-acting pump according to this Invention the pump
barrel or cylinder may be fixed in a horizontal position or in an upright
position: When the barrel or cylinder of a force pump is fixed in a
horizontal position, the piston rod works through a stuffing box formed on
one of the end covers of the cylinder or barrel: At each end of the cylinder
or barrel, and at its under side is formed an induction way or opening for
the water from the source of supply to enter the cylinder or barrel. To this
opening or induction way is fixed the upper end of a suction or supply pipe
having a lifting valve in a valve chamber forming part of the cylinder where
-

page_text: the suction pipe is fixed by means of a screw, coupling, or otherwise, so as
readily to admit of the valve being got at when desired at the upper side,
and at each end of the cylinder or barrel is formed an outlet passage for
the water to pass out of the cylinder or barrel; over each of these outlet
passages is a valve which is arranged to open outwards, and connected with
each passage is a pipe to convey the water in any desired direction or
directions. Hence it will be seen that there are two suction pipes one at
each end of the cylinder or-barrel, and also two outlet pipes, one at each
end of the cylinder or barrel, by which arrangement any desired sizes of
inlet and outlet passages may be obtained, and the water allowed to enter
and to leave the cylinder or barrel with great freedom. When the cylinder
or barrel of a force pump, constructed according to my Invention, is fixed in
an upright position, then the lower induction valve chamber to which one of
the induction pipes is fixed forms part of the lower cover of the cylinder or
barrel, whilst the induction pipe for the upper end of the cylinder or barrel
is fixed to a valve chamber forming part of the upper cover of the cylinder.
or barrel. The outlet passages and the valve,chambers thereto are formed
at the side of the barrel or cylinder; by this arrangement, as in the one
previously described, there are two induction pipes and two outlet pipes.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Joseph Reader in the Great Seal Patent Office
on the 15th September 1866...
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
JOSEPH READER,, of 17 and, 20, Cullum, Street, Fenchurch Street, in the City
of London, send greeting.
WHEREAS, Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of March, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, 'for Herself, Her heirs and successors, give and grant unto me,
the said Thomas Joseph Reader, Her special licence that I, the said Thomas
Joseph Reader, my executors, administrators, and assigns, or such others,
as L, the said Thomas Joseph, Reader, my, executors, administrators, 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

page_text: Invention for "IMPROVEMENTS IN FORCE PUMPS," upon the condition (amongst
others) that I, the said Thomas Joseph Reader, my executors or adminis-
trators, 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 Thomas Joseph Reader, 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 thereof, that is to say :-
This Invention has for its object improvements in force pumps.
In constructing a double-acting pump according to this Invention the pump
barrel or cylinder may be fixed in a horizontal position or in an upright
position. When the barrel or cylinder of a force pump is fixed in a horizontal
position, as is shown in Figures 1, 2, and 3 of the Drawings annexed, the
piston rod 6 works through a stuffing box formed on one of the end covers of
cylinder or barrel a, a. At each end of the cylinder or barrel a, a, and at its
under side, is formed an induction way or opening c for the water from the
source of supply to enter the cylinder or barrel. To this opening or induction
way is fixed the upper end of a suction or supply pipe d having a lifting
valve e in a valve chamber of forming part of the cylinder, where the suction
pipe d is fixed by means of a screw coupling or otherwise so as readily to
admit of the valve e being got at when desired. At the upper side and at
cach end of the cylinder or barrel is formed an outlet passage 9 for the water
to pass out of the cylinder or barrel a; over each of these outlet passages
is a valve h which is arranged to open outwards, and connected with each
passage is a pipe i to convey the water in any desired direction or directions.
Hence it will be seen that there are two suction pipes d, d, one at each end
of the cylinder or barrel a, and also two outlet pipes i, i, one at each end of
the cylinder or barrel a. By which arrangement any desired sizes of inlet
and outlet passages may be obtained, and the water allowed to enter and to
leave the cylinder or barrel a with great freedom.
When the cylinder and barrel of a force pump constructed according to
my Invention is fixed in an upright position, as is shown in Figures 4, 5, 6,
and 7 of the Drawings annexed, then the lower induction valve chamber f, to
which one of the induction pipes d is fixed, forms part of the lower cover of
the cylinder or barrel a, a, whilst the induction pipe d for the upper end of
the cylinder or barrel a is fixed to a valve chamber f. connected with the

page_text: upper cover of the cylinder or barrel a. The outlet passages g, g, and the
valve chambers thereto are formed at the side of the barrel, or. cylinder a.>
By this arrangement, as in the one previously.. described, there are two.
induction pipes and two outlet pipes.
:.In' witness whereof, I, the said Thomas Joseph Reader, have hereunto
I set my hand and seal, this Twelfth day of September, in' the year of
our Lord One thousand eight hundred and sixty-six..
