Year: 1866

page_text: LETTERS PATENT to William Henry Phillips, of Nunhead, in the County
of Surrey, Engineer, for the Invention of "IMPROVEMENTS: IN ROTARY
PUMPS."
Sealed the 3rd October 1866, and dated the 5th April 1866...
PROVISIONAL SPECIFICATION left by the said William Henry Phillips at
the Office of the Commissioners of Patents, with his Petition, on. the
5th April 1866.
I, WILLIAM HENRY PHILLIPS, of Nunhead, in the County of Surrey, Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
ROTARY PUMPS," to be as follows:-
My Invention consists in so arranging rotary apparatus for lifting and
forcing water or other fluids that the momemtum communicated to such fluids.
by the rotation of the apparatus may be used as a constantly accumulated
force for lifting and raising the fluid, in place of such force being allowed to...
disperse itself as in rotary pumps,, where the fluid is lifted and forced by the:
action of centrifugal force only..
In carrying out my Invention, according to the mechanical arrangement: of
parts I prefer to employ, I mount a circular chamber upon a stationary
hollow axis, such chamber being caused to revolve upon such axis with
considerable velocity. Upon the stationary bollow axis, and. within the

page_text: revolving chamber, a cylindrical drum or chamber or one or more pipes is
fixed, and one or more passages are so formed around the circumference of
the fixed chamber or at the ends of the pipes, the openings being so formed as
to be in a direction opposite to the motion of the revolving chamber. Orifices
are formed through the hollow axis forming communications between the
interior of the revolving chamber, other orifices being formed through the
hollow axis communicating with the interior of the fixed drum, and a division
is placed in the hollow axis between the orifices communicating with the
outer and inner drum. One end of the hollow axis is connected by a pipe or
hose with the fluid to be raised, and upon causing the chamber above described
to revolve such fluid will be drawn through the supply pipe into the hollow
axis and through the first set of orifices into the revolving chamber, and by
the centrifugal force the fluid will be driven against its inner periphery.
Division plates or vanes may be fixed against the sides and in the periphery
of the revolving chamber, which by its continued revolution will force the
fluid by means of the momentum communicated to it through the passages
into the interior of the stationary drum, and from thence through the orifices
in the hollow axis, from which it will be forced into any suitable discharge
pipe or passage. The revolving drum may be buoyed up by surrounding it
with a chamber containing water or other fluid.
I would remark that the above arrangement of mechanical parts may be
greatly varied; for instance, the drum which by its revolution imparts the
momentum to the fluid may be enclosed within a fixed chamber to which
suitable inlets and outlets are provided, the revolving drum being fixed on an
axis to which motion is communicated outside the fixed chamber.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Henry Phillips in the Great Seal Patent Office' on
the 5th October 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENRY PHILLIPS, of Nunhead, in the County of Surrey, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of April, in the year of our Lord One
thousand eight hundred and sixty-six, in the twenty-ninth, year of Her reign,
did, for Flerself, Her heirs and successors, give and grant unto me, the said
William Henry Phillips, Her special licence that I, the said William Henry

page_text: Phillips, my exécutors, administrators, and assigns, or such others as I, the
said William Henry Phillips, 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 for "IMPROVEMENTS IN ROTARY PUMPS," upon the condition (amongst,
others) that I, the said William Henry Phillips, 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 Henry Phillips 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:
My Invention consists in so arranging rotary apparatus for lifting and forcing
water or other, fluids that the momentum communicated to such fluids by the.
rotation of the apparatus may be used as a constantly accumulated force for
lifting and raising the water or other fluid, in place of such force being allowed
to disperse itself as in rotary pumps, when the fluid is lifted and forced by the
action of centrifugal force only.
.
In carrying out my Invention I prefer to mount a circular chamber upon a
stationary hollow axis, such chamber being caused to revolve upon such axis
with considerable velocity.
And in order that my Iuvention may be most fully understood, and readily
carried into practice, I will proceed to describe the Drawing hereunto annexed.
DESCRIPTION OF THE DRAWING.
Figure 1 shows a longitudinal section, and Figure 2 a transverse section,
of a rotary pump for lifting and forcing water or other fluids arranged and
constructed according to my present improvements. Upon the stationary
hollow axis a, and within the revolving chamber b, a cylindrical drum or
chamber c (or it may be one or more fixed conducting pipes) is fixed. One
or more passages c¹, c¹, are formed around the circumference of the fixed
chamber c (or at the outer ends of the fixed pipes), the openings, cl, c', being
so formed as to be in a direction opposite to the motion of the revolving
chamber 6.

page_text: Inlet orifices or passages a¹, a¹, are formed through the hollow axis a,
forming communications between the interior of the revolving chamber b, outlet
orifices or passages c, c, being formed through the hollow axis a communi-
cating with the interior of the fixed drum c, and a division is placed or
Trranged in the hollow axis a, between the orifices or passages a'and c³, communi-
cating with the outer revolving drum or chamber 6 and the inner fixed drum
or chamber c. The end a' of the fixed hollow axis a is connected by a pipe or.
hose with the water or other fluid to be raised or forced, and upon causing the
chamber b above described to revolve by means of a driving strap or band
from a steam engine or other motive power passing over the driving pulley b¹
(forming part of the revolving chamber in the arrangement shown), the
water or other fluid will thus be drawn through the supply pipe a into the
hollow axis a, and thence through the first set of orifices or passages a¹ into
the revolving chamber 6, as indicated by the arrows, and by the centrifugal
force the fluid will be driven against the inner periphery of the revolving
chamber b. Division plates or vanes 6, 63, may be cast on or fixed against
the sides and around the inner periphery of the revolving chamber 6, which.
by its continued revolution will force the water or other fluid (by means of the
momentum thus communicated to it) through the passages c¹, c, into the
anterior of the stationary drum or chamber c, and from thence through the
orificesc, c, into the hollow axis a, from the outlet a of which it will be
forced into any suitable discharge pipe or passage connected therewith. An
air vessel or chamber may be combined with the outlet pipe or passage if
desired to equalize or accumulate pressure as is well understood. Suitable
valves are applied to the inlet pipe or passage to prevent the admission of
substances injurious to the action of the apparatus, and the parts are so
arranged as to afford ready access to the interior of the apparatus when
required.
The several parts of the apparatus shown are, by preference and for
convenience, made of cast iron; but I do not confine myself thereto as other
metal or materials may be employed in the construction of rotary pumps
according to my Invention if desired. The weight of the revolving drum &
may, if desired, be buoyed up by surrounding it with a chamber containing
water or other fluid.
I would remark that the above arrangement may be greatly varied, and
that the drum b, which by its revolution imparts the momentum to the water
or other fluid, may be enclosed within a fixed chamber to which suitable inlets
and outlets are provided, the revolving drum b in this arrangement being fixed
on an axis a, to which motion is communicated outside the fixed chamber c'.

page_text: Figure 3 shows a longitudinal section of an arrangement of this character,
in which a is the revolving axis, on which the revolving drum or annular ring
chamber b is fixed; a' being a driving pulley for giving motion thereto. The
inlet and outlet passages in this arrangement are formed in combination with
the collecting circular chamber c and with the outer fixed case or chamber
c. The inlet pipe or passage conducts the water or other fluid into the
annular space c³, from which it passes into the interior of the revolving chamber
b, and the momentum it acquires at the inner periphery forces it through the
openings or passages c*, and thence to the outlet passage ; the outlet passages
c* being of similar character to the passages c¹ of Figures 1 and 2. The
manner of constructing and arranging rotary pumps in accordance with my
improvements may be greatly varied without departing from the true character
of my Invention, which consists in the application of the force produced by the
momentum of the water or other fluid as it is carried round against the inner
circumference of a rotating drum or chamber, in order to discharge currents
through suitable discharge orifices arranged within the revolving chamber.
And I would remark that I do not claim the use of such apparatus for forcing
water for the purpose of extinguishing fires, a Patent having been granted to
me for this purpose bearing date October 5th, 1865, No. 2559; but I find
that apparatus of this character may be advantageously employed for lifting
and forcing water for a variety of useful purposes, particularly for discharging
a column of water for propelling vessels.
In witness whereof, I, the said William Heury Phillips, have hereunto
set my hand and seal, this Fourth day of October, in the year of our
Lord One thousand eight hundred and sixty-six.
