page_text: LETTERS PATENT to Michael Henry, of 68, Fleet Street, in the City of
London, Patent Agent, for the Invention of "IMPROVEMENTS IN CENTRI-
FUGAL PUMPS, AND IN THE JOINTS OR JUNCTIONS OF PIPES AND TUBES."-A
communication from abroad by Louis Coignard, of 33, Boulevart Saint
Martin, Paris, France.
Sealed the 31st May 1867, and dated the 19th December 1866.
PROVISIONAL SPECIFICATION left by the said Michael Henry at the
Office of the Commissioners of Patents, with his Petition, on the
19th December 1866.
I, MICHAEL HENR., of 68, Fleet Street, in the City of London, Patent
Agent, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN CENTRIFUGAL PUMPS, AND IN THE JOINTS OR JUNCTIONS OF PIPES AND TUBES,"
communicated to me from abroad by Louis Coignard, of 33, Boulevart Saint
Martin, Paris, France, to be as follows:-
The wheel is divided by helical, winding, or spiral vanes of two or more
threads or turns, their curve being generated by two lines, each having one
end tangential to the boss of the wheel, and each moving in the direction of
its axis in parallel planes, and also in a direction round such axis, so that in
their path their point of contact describes a helicoidal curve on the surface of
the boss, supposing it to be cylindrical. The wheel is thus divided into spiral
Perine Rd 1

page_text: channels whereof the surfaces are so inclined that when the fluid is admitted
they act upon it and work through it without concussion, and carry it by gentle
curves to the periphery, where they leave it in a direction as tangential
thereto as may be, the vane terminating in a surface which meets the sides of
the wheel very obliquely and in the line of the generatrices of the vane, that is
to say, at a very inclined curve or acute angle to the sides. The wheel is so
constructed that an annular opening is left for the exit of the fluid, such
opening being formed by the sides of the wheel it of course turns with the
vanes,so that the water issues at or nearly at-right angles to-the plane of the
wheel instead of in the direction of the plane of rotation. This may be done
thus, the outlet side is extended and bent or formed so as to extend
beyond the vanes and leave between itself and the other side of the wheel an
annular or circular opening parallel or nearly so with the plane of rotation
and the water issues thence. The wheel does not turn directly in the receiver
into which the water is forced but in a casing in which it turns close to but
not quite in contact with the same, no packing being required. The pump
may have its sides open at the centre so that air may be withdrawn from one
end while the water enters freely at the other. A suction pump or air pump
may be combined with the centrifugal pump and worked by its axis through
a worm wheel or otherwise (with appliances for putting it out of gear at
pleasure); it draws the air from the centre of the wheel and drives it into
the force pipe or elsewhere. An air pump for extracting or exhausting air
may be applied to or combined with centrifugal pumps other than those cou-
structed according to this Invention. Sometimes the pump axis may be
vertical, the water being introduced at top, and if the pump be submerged
no suction pipe, trap valve, stuffing box, nor air pump will be required, one
of the sides not being open at the centre.
Two such wheels or pumps may
be mounted on one axis, their suction sides towards each other, the suction
passage being between them. No packing is required at the suction but only
at the force opening. The axis midway between the wheels may be sur-
rounded by a chamber wherefrom the air is extracted, and instead of using a
pump an air hole may be made in the top of the chamber. The chamber
into which the water is forced may form a circular or annular chamber
whereof the sections taken through the planes containing the axis of the
pump are equal. Sometimes two such pumps may be mounted on one axis
with the delivery ends towards each other. In order that the pipes or
passages fitted to the pumps may be readily turned they may be connected by
moveable flanges made of wrought iron or other like material and placed in
position before casting the pumps. The same arrangements may be applied

by the said Michael Henry in the Great Seal Patent Office on the
19th June 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MICHAEL
HENRY, of 68, Fleet Street, in the City of London, Patent Agent, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of December, in the year of our
Lord One thousand eight hundred and sixty-six, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Michael Henry, Her special licence that I, the said Michael Heury,
my executors, administrators, and assigns, or such others as I, the said
Michael Henry, 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
CENTRIFUGAL PUMPS, AND IN THE JOINTS OR JUNCTIONS OF PIPES AND TUBES,"
communicated to me from abroad by Louis Coignard, of 33, Boulevart Saint
Martin, Paris, France, upon the condition (amongst others) that I, the
said Michael Henry, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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 Seul Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Michael Henry, 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, as communicated to me, reference being had
to the accompanying Drawings, and to the letters and figures marked
thereon, that is to say:-
The Invention relates to centrifugal pumps consisting of two main portions,
one being a revolving wheel in which centrifugal force is developed, and the
other is a stationary casing surrounding it. The wheel is divided by helical,

page_text: winding, helicoidal, or spiral vanes of two or more threads or turns, their
curve being generated by two lines, each having one end tangential to the
boss of the wheel, and each moving in the direction of its axis in parallel
planes, and also in a direction round such axis, so that in their path their
point of contact describes a helicoidal curve on the surface of the boss, sup-
posing the boss to be cylindrical. The wheel is thus divided into spiral channels,
whereof the surfaces are so inclined that when the fluid is admitted they act
upon it and work through it without concussion, and carry it by gentle curves
to the periphery, where they leave it in a direction as tangential thereto as
may be, the vane terminating in a surface which meets the sides of the wheel
very obliquely, and in the line of the generatrices of the vane, that is to say,
at a very inclined curve or acute angle to the sides. The wheel is so con-
structed that an annular opening is left for the exit of the fluid, such opening
being formed by the sides of the wheel it of course turns with its vanes, so
that the water issues at or nearly at right angles to the plane of the wheel
instead of in the direction of the plane of rotation. This is done thus,-
the outlet side is extended and bent, or formed so as to extend beyond the
vanes and leave between itself and the other side of the wheel an annular or
circular opening parallel or nearly so with the plane of rotation, and the
water issues thence. The wheel does not revolve directly in the receiver into
which the water is forced, but in a casing in which the wheel turns close to
the sides of such casing but not quite in contact with the same, no packing
being required. The pump may have its sides open at the centre, so that air
may be withdrawn from the one end while the water enters freely at the other.
A suction pump or air pump may be combined with the centrifugal pump and
worked by its axis through a worm wheel or otherwise (with appliances for
putting it out of gear at pleasure); it draws the air from the centre of the
wheel and drives it into the force pipe or elsewhere. An air pump for
extracting or exhausting air may be applied to or combined with centrifugal
pumps, other than those constructed according to this Invention. Sometimes
the pump axis may be vertical, the water being introduced at top, and if the
pump be submerged no suction pipe, trap valve, stuffing box, or air pump will
be required, one of the sides not being open at the centre. Two such wheels
or pumps may be mounted on one axis, their suction sides towards each other,
the suction passage being between them, no packing is required at the suction,
but only at the force opening. The axis midway between the wheels may be
surrounded by a chamber wherefrom the air is extracted, and instead of using
a pump an air hole may be made in the top of the chamber. The chamber
into which the water is forced may form a circular or annular chamber,

page_text: whereof the sections taken through the planes containing the axis of the pump
are equal to each other. Sometimes two of these pumps may be mounted on
one axis with their delivery ends towards each other. In order that the pipes
or passages fitted to these pumps may turn readily, they may be connected by
moveable flanges made of wrought iron or other like material, and placed in
position before casting the pumps. The same arrangement may be applied to
elbow and other pipes, and to joints of flexible and other tubes and pipes.
The accompanying Drawings exemplify these improvements.
Figure 1 is a longitudinal sectional elevation, Figure 2 an end view, and
Figure 3 a plan of a pump constructed according to this Invention, and
having one centrifugal wheel; Figure 4 is a view of this wheel.
A is the centrifugal wheel, it consists of a chamber connected by arms or
vanes of particular form with a boss a keyed on an axis B, to which rotary.
motion is communicated by means of gearing 6, or other ordinary contrivance,
thus causing the wheel A to revolve. The wheel A is open at its pole or
end d, and it may also be open if desired at its pole or end c. An annular
opening or slot e is formed in its periphery. The fluid enters the wheel at the
centre and issues from it at the periphery. The wheel A revolves within a
stationary casing C, C, C, furnished with a short tube D, into which the
inlet passages or suction pipe leads; the casing is also furnished with a
short tube E, into which the exit passage or force pipe leads. The wheel
is separated by a fixed base plate from the water contained in the force
chamber F.
In the example shown in these Figures, the wheel A is formed on one side
by a flat surface f, and on the opposite side by a curved surface g, the shape
of which is a figure generated by a curve which runs into the inlet or passage
through which the water enters the pump. These two sides f, g, are united
together, and they are connected with the boss a by the vanes h; these vanes h.
are plates formed of winding, spiral, or helicoidal surfaces, they are of a
peculiar spiral form; this, in the instance represented in the Drawings, has
two threads or turns, but it may have more than two. This spiralis generated
by the motion or path of two curved lines, which have one end tangential to
the boss of the wheel, and move in the direction of the axis of such boss in
planes parallel to each other, while at the same time they move in a direction
around the boss, so that in this compound motion their point of contact may
be said to describe a helicoidal path on the surface of a boss supposed to be
cylindrical. The interior of the wheel A is thus formed of passages or fluid
ways curved spirally, and the surfaces which carry the fluid in the wheel
towards the outlets are inclined in such manner that they strike the fluid and

page_text: pass through it on its entering the wheel without disturbing it violently, and
carry it by gentle curves to the periphery where they leave it; the fluid as it
parts from the vanes pursues a direction which is in a line as tangential as
possible to the said periphery. For this purpose the vane terminates in a line
which meets the sides f, g, of the wheel in a very oblique direction, and the
surfaces of the vane intersect with the sides of the wheel according to the
generatrices of the vanes, and the curve thus presented is sharply inclined
towards the periphery and forms a very small angle therewith. The arrow i,
Figure 4, indicates the direction in which the water enters the wheel while
the latter is revolving in the direction indicated by the arrow j.
I do not lay down in this description any one particular curve as being
absolutely essential to the success of the Invention, as many curves will be
suitable; however, I especially mention a spiral line as being particularly
suitable for adoption as a generatrix of the vanes, and as the best mode of
obtaining the results above set forth. The fluid is not delivered from the
wheel in the direction of the plane of rotation of the vanes, but the side g is
extended and bent or curved in such manner as to conceal the vanes, and yet
so as to leave between its inner side and the ends of the vanes a free con-
tinuous annular space or slot / quite open at the sides f, the plane of which is
parallel or nearly so to the plane of rotation, in which the fluid is delivered
from the wheel, and from this said slot or outlet / the fluid is expelled from
the wheel in a direction nearly at right angles to the plane of the wheel. The
water passes into a receiver or passage F', which I call the force chamber, and
from which the force pipe E leads. The wheel A is freely suspended in its
casing C, C¹, C, its outer surface comes as close as possible to the inner
surfaces of the casing, but it is not in actual contact therewith, and it does
not require packing, the wheel has thus sufficient play to turn in the casing
without touching it or rubbing against it at any point. Thus, as shown in
Figure 1, the wheel turns between stationary sides which form its casing
instead of turning directly in the force chamber or receiver into which the
water is forced; the wheel therefore cannot transmit its motion to the fluid
mass contained in the force chamber, and thus it will only carry with it by its
frictional action the very slender film of water which is between its outer
surface and the close sides of its fixed casing.
In the single wheel pumps, Figures 1, 2, and 3, the two sides of the wheel
are open at the centre, as if the fluid entered at both sides. In this arrange-
ment the air may be withdrawn from one of the poles or ends c, so as to allow
of the fluid being freely admitted through the opposite pole or end d. G is a
single-action suction and force pump, which is used for removing the air which

page_text: may happen to collect in the centre and affect the priming of the pump.
This air pump G is actuated by the axis of the centrifugal pump A by
means of a worm or endless screw keyed on the axis in gear with a worm
wheel, on which is the stud which works the crank of the piston rod
of the air pump, but other gearing may be used. A clutch or disengaging
arrangement may be used in order to throw the air pump into and out of gear
with the axis of the centrifugal pump A as required; the air pump G draws
air from the centre of the wheel through the opening c and a pipe m, and
forces it out through a passage n into the force pipe or delivery pipe of the
centrifugal pump, or if the arrangements of the outlets or force pipes should
render this inconvenient the air pump may discharge its air elsewhere. I wish
it to be understood that this air pump can be combined in like manner with
centrifugal pumps of constructions other than those herein described.
As in the arrangement of centrifugal pump, above described, the water is
admitted threugh one pole or end of the wheel ouly; the pumps may be used
with advantage for the pumping of water from wells and for like objects. For
such purposes the pump is upright, that is to say, its axis is vertical, and it is
arranged in such manner that the water may be admitted at top. If the
pump be submerged it will not require a suction pipe, foot valve, stuffing box,
or air pump. In these pumps the plate is not open at the centre, so that the
weight of the wheel and its rod will be balanced by the pressure of the column
of water forced out from the pump, as hercin-after explained.
In Sheet 2, Figure 5 is a vertical section, and Figure 6 a horizontal
section of a double or compound pump, that is to say, the arrangement in
which two or more of the wheels or pumps above described are mounted on
one axis; Figure 7 is a section of the same taken through the axis of the
suction pipe. In this arrangement, which I call the ordinary speed compound
pump, the streams discharged from the two wheels are conducted into one
and the same force pipe or delivery outlet; this pump may be described as
consisting of two single centrifugal wheels or pumps constructed as above
described and mounted on one axis, opposite each other, symmetrically by their
like poles, that is to say, those wheels or pumps are disposed on the axis side
by side, as shewn in the symmetrical manner represented in the Figures. In
the example shown in Figures 5, 6, and 7 the two wheels are connected
together opposite each other by their suction passages, and the water is
admitted between the two wheels; this pump has this advantage, that it does
not require a stuffing box at the suction end. P is a stuffing box at the force
pipe end.
An air pump may be combined with this pump, as described in
reference to the single wheel pump. The air is drawn in through a pipe which

page_text: surrounds the portion of the axis B that lies between the two wheels A, and
on this pipe is a passage which communicates with the air pump, but as
afterwards described these suction pumps can expel the air they may contain
without requiring an air pump or other appendage. H, in all the preceding
Figures 1 to 7 inclusively, is a plummer block or pedestal which supports the
axis B; two such supports are generally used in order that no portion of the
axis may lie in the water. T is a casting or frame on which the compound
pump is supported; but of course any convenient arrangement of framing or
support may be used.
Inext proceed to describe the reduced speed compound pumps,thatis to say,
double or compound pumps in which the lifting power of each one of all the
wheels are combined together, instead of the streams forced from the wheels.
Figure 8 is a longitudinal vertical section of one of these reduced speed,
compound pumps; it consists of two or more wheels or pumps constructed
like the pumps referred to in the description of the preceding Figures, but, as
before stated,instead of the streams delivered from the pumps orwheels being
combined their lifting actions or powers are combined; Figure 9 is a vertical
section on the line x of Figure 8. If a pump receives water from a vessel
situated above it and have to lift it into a second vessel placed over the first
it would only have to make one effort, or if it is a centrifugal pump it would
only have to revolve at a velocity corresponding with a height equal to the
difference of the levels of the two superimposed vessels. A like result would
be obtained if two pumps were worked at the same time, and if the water
forced out of the one were conveyed to the suction pipe of the other. The
first would raise water through the second in the force pipe of the latter to
a certain height, and the second would only have to lift it from this point to
the point at which the water is to be discharged, and so on for the others if
there are more than two. Now in this arrangement the velocity of the
wheels at the periphery, and hence the number of revolutions with a given
diameter may be reduced as required, so that they will lift water to any desired
height.
The pump shown in Figures 8 and 9 is an example of this improved con-
struction; it consists of two centrifugal wheels A,A¹,separated by a partition B.
The water forced out from the wheel A passes into the wheel A' through a
passage C, partly represented in red lines. The pump being thus arranged,
and its centrifugal wheels being of the same diameter (though this latter
point is not essential), they will only revolve at a velocity corresponding with
half the height to which the pump really lifts the water. In this arrangement
stuffing boxes are not required at the suction passages.
The pump is

page_text: furnished with air chambers a, a¹, Figure 8, and X, Figure 5, perforated at
top at y, Figures 5 and 8, by means of which it will eject into the force pipes
all the air which it receives from its suction pipe without requiring the
addition of an air pump. This arrangement of air chamber can be used iu like
manner in centrifugal pumps of other constructions than those described in this
Specification. D is the suction pipe, and E the force pipe. If the pump has
nore than two centrifugal wheels the following arrangements may be used:-
When the pump is at work the water between the outer sides of the wheel
and the inner sides of the stationary casing exerts at that part a pressure
proportionate to the height to which it is forced, which is in equilibrio on each
side of the wheel, except at the part of the side which is closed at the centre,
and which comes opposite the portion of the side open at the other pole for the
admission of water. The result is a sort of thrust which tends to displace
the wheel and to force it in a direction opposite to that in which the water is
drawn in; the effect of this thrust must be neutralized. In the single
wheel pumps an opening is made at the centre of the wheels in the flat side,
the sectional area of such opening being equal to that through which the
suction takes place; but in the compound pumps the effects of the said
thrust are neutralized by different means, varied according as to whether the
axis of rotation is horizontal or vertical. If the axis is horizontal the thrust
is neutralized by so arranging the pump that the sum of the effects of the
thrusts on the wheels whereof the threads or spirals of the vanes are directed
towards the right are equal to the sum of the thrusts which are exerted in a
contrary direction on the wheels, the threads or spirals of whose vanes are
directed to the left. In pumps which have horizontal axes the direction of
suction of the wheels whereof the spirals of the vanes are to the right are in
an opposite direction to that of the suction of the wheels whose vanes have
their spirals directed to the left, and the suction pipe is placed within the
pump or wheel. It is obvious that equilibrium will be obtained by com-
bining a number of pumps in which equilibrium is produced as above, such
pumps being mounted on the same horizontal axis and all arranged so that
each one shall force water into the suction pipe of the next. If the axis of
rotation is vertical equilibrium may be otherwise obtained. The wheels here
revolve in the same direction, their suction openings being on the upper side.
The thrusts made in those closed parts of the wheels which are opposite the
inlets, and which thrusts are exerted as above described in a direction opposite
to the direction in which the water enters the wheels, and the action of such
thrusts being combined with each other, are brought into equilibrium while

page_text: the pump is in action by the weight of the wheels and their rods which is
exerted in a contrary direction.
The Drawings do not represent this vertical arrangement, as their action
may be readily understood from what precedes, but it may be added that the
combination which the Inventor thinks most convenient consists in super-
imposing a series of single wheel pumps in which the force chamber instead
of having the pipe placed as usual is connected by a central tube with the
suction pipe of the wheel or pump-next below it, and-so-on-as regards-the
others. The same arrangement may be used for pumps with horizontal
axes, in which case a set of wheels whereof the spirals of their vanes in one
direction are placed opposite a like set of wheels having the spirals of their
vanes in a contrary direction. In this instance the suction pipe is within
the pump, and the pumps which have more than one wheel do not require
stuffing boxes in their suction pipes.
I wish it to be understood that this arrangement in which the suction pipes
are placed within centrifugal pumps may be applied to centrifugal pumps of
constructions other than those herein described. In punips which have vertical
axes, the axis passes through the suction passage. The Inventor recommends
that the pumps be completely submerged as they then do not require stuffing
boxes nor foot valves, but when that is impossible and when an outside suction
pipe is required, a tight packing must be employed at the part at which the
axis passes through this suction passage. Instead of an ordinary stuffing box
a hydraulic joint may be used constructed as follows:-The stuffing box e,
Figure 10, which is disposed as usual or nearly so (for it may be a little more
shallow) it is closed merely by a valve or disc b, in leather or other elastic or
plastic material which on the inside is of the shape of a hollow cone, the base
of which is turned towards the opening through which the air enters; the
open part of this cone is filled by the packing e which is rolled round the axis in
such manner as to form a sort of cushion, on one side of which the flat flange d
is pressed, and on the other side it is pressed against the axis by the cone.
Water is introduced into the stuffing box e through a small passage f pro-
ceeding from the force pipe, such water being always kept at a certain
pressure; g is a collar or washer placed in the boxe and turuing with
the pump axis. The front face of this collar is grooved in such manner, as
to carry the surrounding water with it in its centrifugal motion. It thus
retains at its central part the air which may penetrate through the flexible
lip of the valve b, and prevents it from being introduced into the pump.
This hydraulic joint may be used for both single and compound pumps, and

page_text: indeed it is applicable to all centrifugal pumps which have their suction pipes
on the outside, and consequently require a tight joint at the part at which the
axis passes through such pipe. o, o, are moveable flanges which are employed
in the improved mode of forming the joints or junctions of pipes and tubes;
this mode is especially useful when applied to the pipes fitted to these pumps,
as it allows of their turning readily and being properly flexible. The move-
able flanges o, o, are made of wrought iron, and they are made and put into
position before the pumps are cast. The same arrangement may be adopted
for the cast metal elbow pipes or bends for other pipes, especially for the
flexible pipes used for drainage purposes.
I wish it to be understood with respect to the use of the air pump, the
internal suction pipe, and the air chamber above described, I do not restrict
their application to the constructions of pump herein described, but the same
may be applied to centrifugal pumps of other constructions, and such appli:
cation is herein claimed.
I also wish it to be understood that I do not confine myself to the particular
mechanical details herein-before described for carrying out the Invention,as
the same may be varied without departing from the nature of the Invention
as set forth.
Having now described the nature of the said Invention, and in what manner
the same may be performed, I declare that I claim, -
First, the construction of wheel and the division thereof into fluid ways
formed of winding, spiral, helical or helicoidal surfaces which impinge upon,
impel, and eject the water, substantially as above described.
Second, the free annular passage which turns with the vanes, whereby the
water immediately on its leaving the vanes does not impinge directly on the
stationary surfaces, but is ejected in a direction at right angles or nearly so to
the plane of rotation, as described.
Third, enclosing the whole surface and periphery of the wheel by a
stationary casing very close to it, but not in contact with it, and which sepa-
rates it from the force chamber, as described.
Fourth, the arrangement of the force chamber in such manner that the
sections thereof in the planes in which is the axis of the pump shall be
substantially equal to each other, as described.
Fifth, the combination of an air pump in the manner described and for the
purpose set forth with centrifugal pumps whether of the construction herein
described or of other constructions.
Sixth, the arrangement whereby the pumps with horizontal axes may be
converted into pumps with vertical axes, as described.

page_text: Seventh, the construction of double or compound pumps, substantially as
described, and I especially claim herein placing the suction pipe within the
pump, as described.
Eight, the improved joint or junction for pipes and tubes herein-before
described according to which moveable wrought-iron flanges are prepared
and placed in position before casting the pumps, as set forth.
Ninth, the employment in centrifugal pumps of a suction pipe placed
within the pump, whereby stuffing boxes, packings, or glands at that-part
may be dispensed with, as described.
Tenth, the employment in centrifugal pumps of an air chamber with dis-
charge opening at top communicating with the force pipe, such chamber
being on or in any part of the suction pipe, so that air may be discharged from
the pump without the use of an air pump, the pump discharging into the
force pipe gases or vapours which it may have drawn in.
And, eleventh, in respect of double or compound pumps or pumps with two
or more wheels whose lifting actions are combined, so that thus combined
they act as a single pump, I claim the use of the arrangements whereby
thrusts tending to displace the wheel may be neutralized, as described.
And, twelfth, I claim the general arrangement and combination of parts
of improved centrifugal pumps herein-before described.
In witness whereof, I, the said Michael Henry, have hereunto set my
hand and seal, this Nineteenth day of June, One thousand eight
hundred and sixty-seven.
