WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Eleventh day of February, in the ninth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Charles Tetley, my exors, admors, and assigns, Her especial licence, full
power, sole privilege and authority, that I, the said Charles Tetley, my
exors, admiors, and assigns, or such others as I, the said Charles Tetley,
my exors, admors, and assigns, should at any time agree with, and no others,
from time to time and at all times during the term of years therein expressed,
should and lawfully might, make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, and in the Islands of Guernsey,
Jersey, Alderney, Sark, and Man, and also in all Her said Majesty's Colonies
and Plantations abroad, my Invention of "CERTAIN IMPROVEMENTS IN MACHINERY
FOR RAISING AND IMPELLING WATER AND OTHER LIQUIDS, AND ALSO THEREBY TO
OBTAIN MECHANICAL POWER;" in which said Letters Patent is contained a
proviso that I, the said Charles Tetley, shall cause a particular description of
the nature of my said Invention, and in what manner the same is to be per-
formed, to be inrolled in Her said Majesty's High Court of Chancery within
six calendar months next and immediately after the date of the said in part

page_text: recited Letters Patent, as in and by the same, reference being thereunto had,
will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Charles Tetley, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, are fully described
and ascertained in and by the following statement thereof, reference being had
to the Drawings hereunto annexed, and to the figures and letters marked
thereon, that is to say :-
In order that my improvements may be understood, reference must be had to
the accompanying Drawings, marked Figures 1, 2, and 3, the first and last of
which are drawn very nearly to a scale of one and a half inch to the foot, and
the second to a scale of very nearly three quarters of an inch to the foot: •
In reference to Figure 1, a is a pipe, the lower extremity of which is sup-
posed to extend down into the water or liquid to be raised. The upper end at
6 diverges into two branches marked c, c. At the top end of each branch is
an air-tight iron box, each of which is marked d, d, and each having a move-
able lid at the side marked e, e. ff.f, is a pipe of small diameter, forming a
passage for air from one box to the other, by which means one exhausting air
pump answers for both boxes. 9, 9, 9, 9, is an iron case made air-tight: i, i,
is a wrought-iron shaft, at one end of which is either a pulley or a toothed
wheel marked j. k, k, are two journals or bearings fixed in the inside of the
boxes d, d, for the purpose of carrying the shaft i, i.
m is a stuffing box,
passes into the box d,
which makes the passage through which the shaft i, i,
air and water tight. n, o, p, is a pipe which joins to the under part of the
case g, g, g, g, by means of the bend at o, and which may, when desirable, be
enlarged at o, and provided with valves opening upwards. In the interior of
the case g, g, is placed a hollow wheel, having hollow spokes or radial arms.
of which q, q, are two; r, r, I call the nave, which is hollow; and s, s, are two
hollow shafts, one at each side of the wheel. t, t, are two stuffing boxes, truly
bored, and the shafts s, s, are truly bored to fit them.
In the interior of the naver there is a boss or plate of metal marked u, which is
cast in at the time the wheel is cast, and which carries the wheel in the manner
shewn in the other section, marked Figure 2.
The shaft i, i, passes through
On the end of each of the
the centre of this plate and is firmly keyed in.
hollow spokes q, q, is fixed a short piece of pipe or tube, made of leather or of
india rubber or other flexible and waterproof material or materials, and which
are marked v and w; the one marked v being shown as open, and the one
marked w being shewn as shut or collapsed. These flexible valves are to be
secured in a firm and air-tight manner on to the ends of the spokes by clamps

page_text: or other secure means. x is an exhausting air pump for drawing air out of
the machine, and y is the piston rod thereof. z, z, are two vanes, a front
view of which (in the interior side) is shown in Figure 3, and which are
fastened on to the shaft i; i, so as to revolve with it. A manhole is to be
provided in some part of the case 9. g, but which is not shewn in the Drawing.
All the parts which have now been described (in Figure 1) are represented in
cross vertical section, with the exception of the air pump, the pipe n, o, p, and
the pipe f f f of which three the Drawing shews merely an external view.
The top end of the pipe n, o, p, the lower part of the pipe a, and the top end
of the pump rod, are represented as broken off, it being to be understood that
of the former the first may be conducted where the liquid is desired to be
conveyed, and the second into the well or liquid to be raised, while the pump
rod may be connected to the moving power in any way most convenient.
Figure 2 represents a vertical section of the hollow wheel already described
in Figure 1, taken through the dotted line c², c², or through the plane in
which the wheel revolves. This Figure is drawn to half the scale of Figure 1.
7, 7, &c., are the hollow spokes; v, v, and w, w, &c., are the flexible valves,
five of which are shewn as open and three as collapsed; u is the boss or plate
of metal carrying the wheel; i is the hole therein for the solid shaft. From
an inspection of this Figure it will be seen how the plate u is made to carry
the wheel, while from an inspection of Figure 1 it will be seen that the hollow
spokes are enlarged in their cross section at the ends next the nave, so as to
admit the liquid to pass at each side of the plate u into the spokes.
The operation of the machine is as follows:-Let the attendant first close all
the flexible valves at the ends of the hollow spokes, and then put the air pump
x into operation to exhaust the air from the interior of the wheel, the boxes d, d,
the pipes c, c, and a. As this exhaustion takes place the liquid will rise up the
pipes'a, and c, c, and fill the boxes d, d, and the wheel. After the exhaustion of
the air just mentioned has begun to take place all the flexible valves will remain
closed and air-tight, in virtue of the external pressure of the atmosphere, so
long as the machine is at rest. After the wheel has become filled with the
liquid, let it be put into rapid rotatory motion by means of the pulley or toothed
wheel j. The speed at which the hollow wheel revolves must be so regulated
as to communicate to the liquid which now fills the hollow spokes such degreé
of tendency to fly off (or out) by virtue of the centrifugal force imparted thereto
as will cause it to force, open the flexible valves, notwithstanding any pressure
of air externally thereon, and fly out. The liquid will be received into the iron
case g, g; as one portion of liquid comes out of the hollow wheel, a corre-
sponding portion will ascend up the pipes a and c, c, to supply its place. Now,

page_text: if it be not intended to raise the water more than twenty-eight or from that to
thirty-two feet, that is to say, not higher than the force of the atmosphere would
lift it in vacuo (computing such distance from the surface of the water to be
raised to the hollow shaft), then the water or liquid may at once be drawn from
the case and conveyed where desired, the machine as now described being
sufficient. In such instances, however, it is not requisite the case should be
air-tight, but may be open at the sides, and in some instances there need be no
case at all. But if it be desired to raise the water higher than such distance
without employing two machines, then the case must be air-tight, and the further
operation will be as follows:-The pipe n, o, p, may be filled with the water or
other liquid to be raised, and either by the aid of a forcing air pump or any
other ready method known for such purposes, the air-tight case is to be filled
or charged with as much compressed air as will balance the column of liquid
in the pipe n, o, p, whatever may be the height of the column, without suffering
the liquid to rise high enough in the case to submerge any part of the wheel.
Means must also be provided to renew such compressed air from time to time
as may be required. Inasmuch as this can always be done by a forcing air
pump, as well as several other methods which are well known, I have not
exhibited any means of doing so in the Drawings, it being unnecessary. Now
the case being filled with air so compressed, and the hollow wheel with its
supply pipes being filled with the liquid to be raised, as before described, then
such speed in the rotation of the wheel must be communicated as will throw
the liquid out of the wheel into the case, notwithstanding the latter being
charged with air so compressed. The liquid so thrown out of the wheel
will fall to the bottom of the case, and the pressure of the compressed air
on its surface will force it out by the pipe n, o, p, with the same velocity
with which the wheel introduces it into the case, and by that means
prevent the liquid rising in the case to impede the rotation of the wheel.
By this means the liquid may be raised the height desired above thirty-two
feet, care being taken to make the case and all the other respective parts
of the strength requisite to sustain the pressure. I would, however, observe
something upon that law of hydraulics by which the motion of liquids
ascending decreases in speed in proportion to the height or length of the
ascending pipe or channel. For example, if the hollow wheel in Figure 1 be
thirty feet above the surface of the water in the well, then the liquid would not
rise up the pipes a and c, c, with near the same velocity as it would do if the
wheel was but twenty feet above the liquid to be raised. Therefore, if the pipes
a and c, c, are made of such diameter as only to have the same area for the
passage of the water up them as is the area of the shafts of the hollow wheel

page_text: they will in such case not supply sufficient water for the wheel. It is found
that the decrease in speed of water ascending perpendicular pipes is nearly as
the square root of the distance between the water to be raised and the point of
discharge. Upon this I found one part of my Invention or improvements,
namely, to make the pipes a and c, c, of such internal area over and above
the internal area of the hollow shafts of the wheel, as will cause them to pass
as much water, notwithstanding the slower motion thereof up such pipes in'
consequence of their length, as will supply the wheel with all it can discharge.
Now, in the Drawing these pipes are shewn of two small a diameter to give full
effect to this improvement if they are of any considerable length. This being
understood, I would now say, that I prefer to make the area of such pipes as
many times greater than the area of the hollow shafts as is the square root of the
distance between the surface of the water to be raised and the said hollow shafts,
or thereabouts. I would next observe, in regard to the vanes marked Z, Z, in
Figure 1, which form another part of my Invention or improvements, that
although I do not consider them necessary to the action of the machine, yet,
in cases where the height of the column of water in the supply pipes a and c, c,
is such as to become nearly a balance to the pressure of the external atmo-
sphere, then by their oblique action upon the water these vanes expedite or
force the water into the wheel, which in some degree becomes necessary in
consequence of the water not being pressed in by the atmosphere with the same
force it would when the column of water in the ascending pipes is a short one.
The screw now in use for propelling steam vessels may be substituted for
these vanes, or their configuration may be varied in any manner so long as
such oblique action upon the water is secured as will expedite its passage into
the wheel.
The operation of the machine having now been explained, and its general
principles exemplified by the Drawings, I now proceed to explain the several
points following, namely:-
Where the terms "liquid" or "water" are used in this my Specification,
I mean the same to imply either water or any other liquid not injurious
to the materials used in the construction of the machine.
In this sense
of course acids are excepted. I do not confine myself to the use of iron where
other metals or other materials may be substituted. I do not confine myself to
the use of pipes or tubes as channels for conveyance of the liquids, but propose
to use vessels of any desired configuration. I do not in all cases propose to
have a solid shaft passing through and carrying the hollow wheel, but in some
cases to dispense with the same, and to cause the hollow wheel to revolve on
its own hollow shaft passing through stuffing boxes. In some cases I propose

page_text: also to dispense with hollow shafts for the wheel, and merely to have an
opening at each side of the nave for admitting the liquid. In some special
cases I propose to have an entrance for the liquid into the wheel at one side
thereof only, and to counterbalance the suction arising therefrom, by producing
a corresponding degree of suction at the other side, without admitting the
liquid at the last-mentioned side. Where the term "suction" is used in this
my Specification, I mean and intend the same to signify the difference pro-
duced by the abstraction or partial abstraction of air from the inside, and the
pressure of air externally to the supply pipes. If any gasses or elastic media,
other than atmospheric air, are used, with which to charge the case, I claim
the sole right to do so. In reference to the hollow wheel, I do not confine
myself to the number or to the use of hollow spokes, but in some cases pro-
pose to substitute circular dises, with a narrow water channel between, and a
valve or flexible valve or valves on the circumference; and generally I propose
to construct the wheel of every variety of configuration so long as the same is
constructed so as to have a channel or channels in the interior thereof for the
passage of liquids, and shall be adapted to neutralize the effects of suction
by having a corresponding or proportionate degree of suction at each side;
nor do I confine myself to a form or configuration or manner of connecting
together any other parts of the machine, but I propose to vary the same.
The manner in which I propose to obtain mechanical power, as signified in the
title of the Patent granted unto me, is by useing water raised by this machine
as a moving power when wind is applied to this machine to raise the water,
such water so raised forming a reservoir of power during the existence of
calms. In reference to the flexible valves at the ends of the hollow spokes, I
prefer to make each of them of two halves or pieces lengthwise, and sewed or
otherwise fastened up each side, by which means they collapse according to
their weakest form, and are thereby rendered more air-proof. In lieu of the
exhausting air pump the machine may be primed by any more convenient and
ready method. In lieu of the stuffing boxes, joints may be made air-tight by
leather, or any suitable means. In some places I propose to place the air-tight
case in the liquid to be raised, dispensing altogether with the supply pipes a
and c, c. I also propose to place the hollow wheel horizontally, or in any other
position as may be desirable.
Having now explained the manner in which my machine operates, or in
which my Inventions act, and pointed out that the machinery by which the
said Inventions act may be varied almost to an indefinite extent in the manner
of its construction, I shall now proceed to explain more particularly what I
claim as my Invention or Inventions. I do not claim to be the discoverer that

page_text: liquids may be raised by centrifugal force, nor do I claim in any way the sole
application of machinery for raising water or other liquids by centrifugal force,
. except only when the same is used as a means of introducing liquids into
compressed air or other elastic fluids, as specified herein-after in my fifth
claim. Now, therefore,-
First, I claim as my Invention and application the means of neutralizing
or diminishing the effects of suction at one side of the wheel by causeing
the same degree (or such other proportionate degree as may be required)
of suction at both sides thereof, whereby a considerable saving of power is
effected.
Second, I claim as my Invention and application the means of increasing
the action of the machine by causing the liquid to enter the wheel at both sides.
Third, I claim as my Invention and application the means of economising
the power required to move the wheel, by causing the same to be mounted on
a solid shaft (or a shaft of small diameter) passing through its centre to carry
the same.
Fourth, I claim as my Invention and application to this machine, or to the
hollow wheel, flexible and collapsible valves, that is to say, valves made of
leather, or leather combined with other suitable flexible substance or substances,
or other suitable flexible and collapsible substance or substances without
leather.
Fifth, I claim as my Invention and application the construction of machinery
for raising and impelling water and other liquids by means of introducing
such water or other liquids into compressed air or other suitable elastic fluid,
in virtue of centrifugal force imparted thereto by such machinery, and causing
such compressed air or other elastic fluid to operate as the lifting, raising,
impelling, or forcing power to impel such water or other liquid upwards.
Sixth, I claim as my Invention the application of an exhausting air pump
to maintain a vacuum of air to such of these machines as act by the mainte-
nance of the vacuum of air in the hollow wheel and its supply pipes.
Seventh, I claim as my Invention and application, where pipes or channels
are used to convey water or other liquids up to the hollow wheel, to make
such pipes or channels of such internal sectional area over and above the area
of the opening or openings into the hollow wheel as will enable them to pass
liquid to supply the wheel at a greater rate than could be done if such pipes or
channels were not of such increased area.
Eighth, I claim as my Invention and application the use of vanes or screws
whose oblique action upon the water shall impel the water more rapidly out of
the supply vessels into the hollow wheel.

page_text: Ninth, I claim the application of the before-mentioned Inventions both
when all used in combination, or when used severally.
In witness whereof, I, the said Charles Tetley, have hereunto set my
hand and seal, the Eighth day of August, One thousand eight hundred
ond forty-civ

DISCLAIMER AND MEMORANDUM OF ALTERATION entered by the said
Charles Tetley with the Clerk of the Patents of England.
WHEREAS the following part of the title of the said Invention, namely,
"and also thereby to obtain Mechanical Power," and the part of the said
Specification contained in the following words, namely, "The manner in
which I propose to obtain mechanical power, as signified in the title of the
Patent granted unto me, is by using water raised by this machine as a
moving power when wind is applied to this machine to raise the water, such
water so raised forming a reservoir of power during the existence of calms,"
have been respectively objected to as not describing or referring to anything of
practical value or utility; wherefore I do declare that I hereby disclaim such
part of the said title of the said Invention, and such part of the said Specifi-
cation respectively.
And whereas it has been alleged that the making pipes or channels for the
supply of water of an area greater than the area of the shaft of the wheel or
the aperture of the raising apparatus was known at the date of the said
Letters Patent, I do hereby déclare that I disclaim the part of the said Speci-
cation contained in the words following, namely:-"Upon this I found one
part of my Invention or improvements, namely." And I also disclaim the
part of the said Specification contained in the words following, namely:-
"which form another part of my Invention or improvements." And I also
disclaim the seventh claim and claiming clause contained in and being part of
my said Specification.
And whereas the following passage of the said Specification, "I do not

generally I propose to construct the wheel of every variety of configuration
"so long as the same is constructed so as to have a channel or channels in the
"interior thereof for the passage of liquids, and shall be adapted to neutralize
"the effects of suction by having a corresponding or proportionate degree
"of suction at each side," has been alleged to include a wheel such as is
described in the two several Specifications of Iales' Patents, which Patents
are respectively dated the Twelfth day of January, in the year of our Lord
One thousand eight hundred and thirty, and the Thirteenth day of October, in
the year of our Lord One thousand eight hundred and thirty-one; wherefore
I hereby declare that I disclaim the words, "and generally I propose to
"construct the wheel of every variety of configuration so long as the same
"is constructed," and the words "shall be" contained in the above-recited
passage of the said Specification.
And whereas it has been objected and alleged that the third, fourth, sixth,
and eighth claims, contained in and being parts of the said Specification, amount
to and are respectively claims of and to distinct and independent Inventions,
I do therefore hereby disclaim such last-mentioned parts of the said Specifi-
cation respectively.
66 For
And whereas no other elastic fluid is more suitable or economical than air.
I therefore disclaim in the said Specification that part thereof contained in
the words following, namely:-"If any gases or elastic media other than
atmospheric air are used with which to charge the case; I claim the sole right
to do so;" and also that part thereof contained in the words following:
other elastic fluids, as specified herein-after in my fifth claim;" and also the
words "or other suitable elactic fluid" in and part of the fifth claim of the
said Specification; and also the words "or other elastic fluid," also in and part
of the same fifth claim. And in order to make the said Specification, after the
parts thereof herein-before mentioned shall have been disclaimed as aforesaid,
consistent, I do hereby declare that I alter the said Specification by expunging
the word "to" in the part of the said Specification following, namely, "to make
the pipes a and c, c, of such internal area over and above the internal area
of the hollow shafts of the wheel as will cause them, &c." And I further alter
the said Specification by adding and substituting the word "I" in the place
and stead of and for the word "to" so expunged as last aforesaid.
And whereas the sentence and words following are contained in and form
part of the said Specification, namely, "this being understood, I would now say
that I prefer to make the area of such pipes as many times greater than the
area of the hollow shafts as is the square root of the distance between the

page_text: surface of the water to be raised and the said hollow shafts or thereabouts, and
it has been pretended and alleged that the said last-mentioned sentence is not
so certain as it might be. Now, therefore, I declare that I alter the said
Specification by introducing to and into the said last-mentioned sentence and
part of the said Specification the words "in feet" immediately after the
word "distance" in the said last-mentioned sentence, and between such word
"distance" and the word "between," also contained in the said last-mentioned
sentence and part of the said Specification. And in order further to make
the said Specification, after the parts thereof herein-before mentioned shall
have been disclaimed as aforesaid, consistent, I do hereby declare that I alter

year of our Lord 1853, the aforesaid Charles Tetley came before our said
Lady the Queen in Her Chancery, and acknowledged the Disclaimer aforesaid,
and all and every thing therein contained and specified, in form above

page_text: In the Matter of a Patent granted to Charles Tetley, or brauiora, m
the West Riding of the County of York, Stock and Share Broker,
for "CERTAIN IMPROVEMENTS IN MACHINERY FOR RAISING AND IMPELLING
WATER AND OTHER LIQUIDS, AND ALSO THEREBY TO OBTAIN MECHANICAL
POWER," bearing date at Westminster, the Eleventh day of February,
One thousand eight hundred and forty-six, and to which a Specifi-
cation has been duly enrolled.
DISCLAIMER AND MEMORANDUM OF ALTERATION proposed to be
entered by the said Charles Tetley with the Clerk of the Patents of
England, pursuant to an Act passed in the fifth and sixth years of the
reign of His late Majesty King William the Fourth, intituled "An Act
to amend the Law touching Letters Patent for Inventions."
WHEREAS near the end of the Specification of the said Letters Patent is
introduced a Disclaimer, by which it was supposed that a wheel described in
the said Specification, whether consisting of hollow spokes or of a channel or
channels between discs, was, when considered apart or separate from the other
machinery, disclaimed; and since the inrolment of the said Specification a
further Disclaimer of certain parts thereof has, according to the Statute, been
entered with and filed by the Clerk of the Patents of England. But it has
lately been held by a Court of Law that notwithstanding these Disclaimers,
such wheel is claimed apart and separate from the other machinery; for
which reason, and in order to make the Disclaimers more certain in regard to
such wheel, and to prevent a like construction being put on the said Specifi-
cation in regard to the separate and individual parts of which the machinery
consists, I hereby alter the Specification by introducing immediately before
the claiming clauses, near the end of the said Specification, the following
words, videlicit, "I disclaim any exclusive right to wheels, whether consisting
"of hollow spokes or of a channel or channels between discs, when considered
"apart or separate from the machinery described. And I also disclaim any
"exclusive right to the parts of the machinery when they are each considered
And I have found that
"apart or separate from the machinery described."
the Invention claimed as the first part of my improvements, though new, has
not come into general use, for which reason I wish to disclaim and I do
hereby disclaim that part of the Specification which is contained in the first.

page_text: claiming clause near the end of the said Specification, and also the following
words, which occur at an early part of the said Specification, "f, ff, is a pipe
of small diameter, forming a passage for air from one box to the other, by
which means one exhausting pump answers for both boxes." Also, further
on in the said Specification, the words "and the pipes f,f,f;" also the word
"three" in the same paragraph, and also the part of the Drawing showing
such pipe and passages thereto; and also the following words, "In some
special cases I propose to have an entrance for the liquid into the wheel at
"one side thereof only, and to counterbalance the suction arising therefrom,
"
86
"
by producing a corresponding degree of suction at the other side, without
admitting the liquid at the last-mentioned side." And I have also found
that the employing compressed air, described in my said Specification, though
useful in the cases mentioned, is beneficial only when in combination with the
other part of my Invention, and that there is consequently no advantage in my
still retaining a claim to compressed air separate from and independent of my
Invention which remains claimed in the said Specification, for which reason
I disclaim the following parts of my said Specification, "except only when
the same is used as a means of introducing liquids into compressed air," and
"Third, I claim as my Invention and application the construction of machinery
for raising and impelling water and other liquids by means of introducing
such water or other liquids into compressed air, in virtue of centrifugal
force imparted thereto by such machinery, and causing such compressed air
to operate as the lifting, raising, impelling, or forcing power to impel such
water or other liquid upwards." And as the last claim contained in the
Specification would be inconsistent and unmeaning after such Disclaimer has
been made, I disclaim the part of my Specification contained in the following
words "Fourth, I claim the application of the before-mentioned Inventions,
both when all used in combination or when used severally."
In witness whereof, I, the said Charles Tetley, have hereunto set my
hand and seal, this Seventh day of April, in the year of our Lord
One thousand eight hundred and fifty-four.

page_text: enrolled. And having considered the said application, and the objections to
the same, I have granted leave to the said Charles Tetley to file his said
Disclaimer and Memorandum of Alteration, pursuant to the Statutes in that
case made and provided.
Dated this Nineteenth day of April, in the year of our Lord One thousand
eight hundred and fifty-four.
AND BE IT REMEMBERED, that on the Seventh day of April, in the
year of our Lord 1854, the aforesaid Charles Tetley came before our said
Lady the Queen in Her Chancery, and acknowledged the Disclaimer afore-
said, and all and every thing therein contained and specified, in form above
written. And also the Disclaimer aforesaid was stamped according to the
tenor of the Statute made for that purpose.
