NEW AND USEFUL USEFUL IMPROVEMENTS IN PUMP3 FOR ELEVATING FLUIDS
Year: 1855

page_text: LETTERS PATENT to William T. Vose, of the State of Massachusetts, of
the United States of America, for the Invention of "NEW AND USEFUL
PROVISIONAL SPECIFICATION left by the said William T. Vose at
the Office of the Commissioners of Patents, with his Petition, on the
26th January 1855.
I, WILLIAM T. VOSE, of the State of Massachusetts, of the United States of
America, do hereby declare the nature of the Invention for "NEW AND USEFUL
IMPROVEMENTS IN PUMP3 FOR ELEVATING FLUIDS" to be as follows:-
Of the accompanying Drawings, Figure 1 denotes a side view of one of my
improved double puinps; Figure 2 is a rear elevation of the same; Figure 3
is a transverse and vertical section of it, the same being taken through both its
barrels and pistons; the said pump, for the sake of illustrating its eduction and
induction pipes, being shown as applied to a reservoir for containing water
or a fluid.
The nature of my Invention consists in a peculiar manner of connecting two
pump barrels, and arranging their 'induction and eduction pipes or passages,
and the valves of their respective pistons, whereby two' valves in or on the

page_text: pistons are all that is necessary to the elevation of water by means of two
pump barrels. For the purpose of carrying out my Invention, two pump
barrels A and B'are employed, they being arranged side by side, and so con-
nected together at two of their adjacent ends by an arched pipe C, that there
may be a free communication between the bores of both. Each of the other
two ends of the said barrels is provided with a pipe (D or E) leading from
it, one of such pipes being the induction and the other the eduction pipe.
In the Drawings, the induction pipe is seen as leading from the lower part
of the reservoir F to the lower end of the pump barrel A, while the eduction
pipe is represented as passing from the lower end of the pump barrel B, and
bent upward, and inade to terminate over. the reservoir, so as to discharge
directly into it.
Each of the barrels A, B, is provided with a piston H or I, the rods of
which respectively play through two stuffing boxes a, b, arranged in the
connection pipe C. These rods are connected together by a cross bar or head
e, which is jointed to a brake or pump handle K, whose fulcrum f is at the
top of a moveable or vibratory rod or standard L, which at its foot is jointed
to the base plate M, by which the pump barrels and their reservoir are
supported.
יד
Each piston is provided with one or more passages h; leading through it,
and each furnished with a' valve, as seen at N or O, the valve of one. piston
being placed on one side or the top of it, while that of the other piston is
disposed on the other side, or the bottom of it, as seen in Figure 3. This
arrangement of the valves with respect to their pistons constitutes an
important feature of my Invention. A pump being so constructed, the two
pistons' are moved simultaneously in the same direction when the brake is in
operation. While the two pistons are being raised or depressed, the valve of
one will be opened, and that of the other closed. When they are raised, the
valve of that belonging to the barrel A is closed, and the air or fluid over
the two pistons will be drawn down through that of the barrel B, water or a
fluid at the same time always passing up into the barrel A, or space below
its piston. During the descent of the pistons, the space over them and in the
-barrels will be increased, so as to cause the valve of the piston of the barrel A
to open, and the water to flow or be drawn into such space, the water that
was in the other barrel and below its piston being drawn out thereof and a
through the induction pipe. Thus, at each upward or downward stroke of the
piston the water or fluid.will, be, elevated by atmospheric pressure, and
forced out of the pump by pressure of one of the pistons. In this pump
only two valves or set of valves are necessary, while in most, if not all, other

page_text: pumps which have two barrels and two pistons, four valves or sets of valves
are necessary. A great reduction of friction in the passage of the fluid
through the valve openings, compared with what occurs in other pumps, as
above mentioned, naturally results; the same not only reducing the power
required to operate the pistons, but also contributing to increase the flow and
delivery of the fluid, or the amount of it elevated. The simplicity of my
improved pump is also another advantage it possesses. As it has but two
sets of valves, it is not so liable to get out of order as it would be had it
four sets.
What I claim consists in connecting the two pump barrels at two adjacent
ends, as described, in combination with not only arranging the valves of their
respective pistons so that one of them shall be applied to one or the upper
side of one piston, while the other is applied to the opposite or lower side of
the other piston, as stated, but applying the eduction and induction pipes
respectively to the disconnected ends of the barrels, substantially as herein-
before specified.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Tileston Vose in the Great Seal Patent Office on
the 3rd May 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
TILESTON VOSE, of the State of Massachusetts, of the United States of America,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of January, A.D. 1855, in the
eighteenth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Tileston Vose, Her special. license that I,
the said William Tileston Vose, my executors, administrators, and assigns, or
such others as I, the said William Tileston Vose, 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 Invention
of "A NEW AND USEFUL IMPROVEMENT IN PUMPS FOR ELEVATING FLUIDS," upon
the condition [amongst others] that I, the said William Tileston Vose, 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
was to be performed, and cause the same to be filed in the Great Seal Patent

page_text: Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said William Tileston Vose, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
Specification and the accompanying Drawings, letters, figures, and references
thereof
Of these Drawings, Figure 1 denotes a side view of one of my improved
double pumps; Figure 2 is a rear elevation of the same; Figure 3 is a
transverse and vertical section of it, the same being taken through both its
barrels and pistons; the said pump, for the sake of illustrating its eduction
and induction pipes, being represented as applied to a reservoir for containing
water or other fluid..
The nature of my Invention consists in a peculiar manner of connecting
two pump barrels, and arranging their induction and eduction pipes or passages
and the valves of their respective pistons, whereby two valves in or on the
pistons are all that is necessary to the elevation of water by means of two pump
barrels. For the purpose of carrying out my Invention, two pump barrels
A, B, are employed, they being arranged side by side, and so connected at
two of their adjacent ends by an arched pipe C, that there may be a free
communication between the bores of both.
Each of the other two ends of the said barrels is furnished with a pipe
[D or E] leading from it, one of such pipes being the induction and the other
the eduction pipe. In the Drawings, the induction pipe is shewn as leading
from the lower part of the reservoir to. the lower end of the pump barrel A,
while the eduction pipe is shown as passing from the lower end of the pump
barrel B, and bent upward, and made to terminate over the reservoir, so as to.
discharge directly into it.
Each of the barrels A, B, is provided with a piston, as seen at H or I, the
ends c, d, of which respectively play through two stuffing boxes a, b, arranged
in the connection pipe C. These rods are connected together by a cross bar
or head e, which is jointed to a brake or pump handle K, whose fulcrum fis
at the top of a moveable or vibrating rod or standard L, which at its foot
is joined to the base plate M, by which the pump barrels and their reservoir
are supported.
Each piston is provided with one or more passages h, leading through it;
and each is furnished with a valve, as seen at N or O, the valve of one piston
being placed on one side, or the top of it, while that of the other piston is
disposed on the other side or bottom of it, as seen in Figure 3. This arrange

page_text: ment of the valves with respect to their pistons constitutes an important
feature of my Invention. A pump being so constructed, the two pistons are
moved simultaneously in the same direction when the brake is put in operation.
While the two pistons are being either raised or depressed, the valve of the one
will be closed, and that of the other opened. When they are raised, the valve
of that belonging to the barrel A is closed, and the air or fluid over the two
pistons will be drawn down through that of the barrel B, water or fluid passing
during the same time up into the barrel A, or space below its piston. During
the descent of the pistons the space over them and in the barrels will be
increased, so as to cause the valve of the piston of the barrel A to open, and
the water to flow or be drawn into such space, the water that was in the
other barrel and below its piston being drawn out thereof and through the
induction pipe. Thus, at each upward and downward stroke of the pistons,
the water or fluid will be elevated by atmospheric pressure, and forced out of
the pump by pressure of one of the pistons. In this pump only two valves or
sets of valves are necessary, while in most, if not all, other pumps which have
two barrels and two pistons, four valves or sets of valves are necessary. A
great reduction of friction in the passage of the fluid through the valve
openings, compared with what occurs in other pumps, as above mentioned,
naturally results; the same not only reducing the power required to operate
the pistons, but also contributing to increase the flow and delivery of the fluid,
or the amount of it clevated. The simplicity of my improved pump is also
another advantage it possesses. As it has but two sets of valves, it is not so
liable to get out of order as it would be had it four sets.
What I claim consists in connecting the two pump barrels at two adjacent
ends, as described, in combination with not only arranging the valves of
their respective pistons so that one of them shall be applied to one or the
upper side of one piston, while the other is applied to the opposite or lower
side of the other piston, as specified, but applying the induction and eduction
pipes respectively to the disconnected ends of the barrels, substantially as
herein-before explained.
In testimony whereof, I have hereunto set my signature and scal, this
Sixth day of April, in the year of our Lord One thousand eight hundred
and Gl fixes.
