AN IMPROVED PUMP
Year: 1884

page_text: We, JOSEPH ARMYTAGE WADE of Hornsea in the East Riding of the county of
York, Timber Merchant, and JOHN CHERRY of Hornsea aforesaid, Brick and -tile
Works Manager do hereby declare the nature of the said Invention for AN
IMPROVED PUMP .to be as follows:-
Our Invention consists in the combination of a revolving screw or screws in
a tube or chamber with any suitable driving apparatus adapted to work the same
for impelling water or other fluid admitted to the said tube or chamber and forcing
it through pipes or otherwise as may be required.
The screw may be varied in form and extent to suit the purpose to which it is
to be applied.
For instance it may be formed with one or more blades continuous and encircling
completely or in part the boss or shaft upon which they shall be set in one or more
spirals or parts thereof and it may consist of several blades similar to a ship's
propeller, or gouge-shaped or in other or in various forms and describing one or
more spirals or part or parts of spirals either cast with or fastened to a casing
which will revolve with the screw or without any such casing and otherwise varied
to suit the particular purpose required-If preferred the surfaces of the screw or
blades may be corrugated.
The screw is or may be fitted so as to revolve within a chamber the internal
diameter of which corresponds or nearly corresponds with the diameter of the
screw so that all fluid admitted to the chamber must be passed through the screw
by the action of its blades or surfaces on such fluids.
This chamber is intermediate between the suction pipe and the delivery pipe
a foot valve being inserted in the suction pipe. The chamber can be opened as
required for the insertion of the said screw.
The driving apparatus may be varied either with or without gearing or strap
between the prime mover and the pumping apparatus as may be required. Also
the screw shaft may be arranged to work either horizontally or vertically and the
form of the pump may be either that of a horizontal body or a vertical barrel or
other suitable form.
In order to overcome the resistance offered to the rising water by the angle at
which the outlet for the water is arranged in relation to the chamber of the pump

page_text: we fix blades or beaters at and round the end of the screw or screws at intervals
and immediately under the outlet in order to aid the suction of the screw and also
to direct the stream of water as required.
If preferred a double right and left handed screw may be used to form a double
suction pump, and in this case the blades or beaters above mentioned would be
arranged round the centre of such right and left handed screw at intervals.

We JOSEPH ARMYTAGE WADE of Hornsea in the East Riding of the County of
York Timber Merchant and JOHN CHERRY of Hornsea aforesaid Brick and Tile
Works Manager do hereby declare the nature of the said Invention for “AN
IMPROVED PUMP" and in what manner the same is. to be performed to be particularly
described and ascertained in and by the following statement:-
Our Invention consists in the combination of a revolving screw or screws in

other suitable form.

In order that our Invention may be fully understood we will proceed to describe
it more particularly by the aid of the accompanying drawings in which are
represented different modes of carrying it into effect.

DESCRIPTION OF THE DRAWINGS.
Fig 1 is an elevation shewing the pump with the front half removed. Fig 2 is
a longitudinal vertical section taken in the line ab of Fig 1 Fig 2 A is a half
horizontal section on the line c d of Fig 1 shewing the screw chamber B and the
water space or channel F in their relative positions-Figures 3 and 4 show another
arrangement in which the beaters and screws are cast within a case which revolves
inside the pump case. Figures 5 and 6 represent another form of beater with
longer screws than those in Fig 2-Figures 7 and 8 show a smaller pump (drawn
to a larger scale) with a long screw at one side only of the case containing the
beaters. In this instance there is only one inlet pipe from the suction pipe and the
water space or channel is differently arranged. Fig 7 represents the said case
detached. Fig 8 is a longitudinal section taken through the pump case shewing
the screw and beater case in full.
In Fig 9 is shown a similar sized pump but drawn to an enlarged scale with
long screw arranged on each side of the beater case and with an inlet pipe at
each side forming the top of the suction pipe. In Fig 10 are shown the beater case
and beaters detached Fig 4 A (Sheet 1) represents in section a different form of
boss the blade of the screw being omitted.
.
In these several figures the same letters of reference indicate corresponding
parts.
A is the pump case B is the Chamber in which the screw C revolves such screw
being fixed on the shaft D which is intended to be driven by any suitable prime
mover and works in stuffing boxes as shown.. EE are beaters combined with or
applied to the screw and adapted to force the water through the water space
or channel F F formed at the top and bottom of the chamber B in which the
screw C revolves.
This Chamber is open at each end for the admission of water into the screw C
through which it passes into the water space or channel F whence it is forced by
the action of the beaters E E revolving with the screw C through the outlet G and
discharged from the pump by the delivery pipe which is not shown.
In the arrangement shown in Figures 1 and 2 the screw C is right and left
handed with the beaters E E between the two parts of the screw and on the water
being drawn into the pump case A from the suction pipe at the bottom it is caused
to pass in the directions indicated by the arrows in Fig 2 and enter the screw
chamber B whence by the revolution of the screw it is lifted to the upper part of
the water space or channel F (of smaller diameter) and being acted upon by the
beaters EE is thereby forced through or along the space or channel F (of larger
diameter) in the direction indicated by the arrows in Fig 1 until it reaches the
outlet at G connected with the delivery pipe.
Figures 3. 4. 5 and 6 merely represent variations of form and arrangement of
the screw and beaters the action whereof in the pump is similar to that above
described.
In Fig 4 A is represented a form of boss with converging curves adapted to lead
up the water to the beaters.
In Fig 8 is shown a pump in which the screw chamber B is open only at one
end for the admission of water from the suction pipe and the screw C is a spiral

page_text: with beaters E E at one end of the screw revolving in a water space or channel F
of a different section from that in Fig 2-In this instance also the screw chamber B
is a cylinder the internal surface of which corresponds or nearly corresponds with
the screw in its external diameter.
And in Fig 9 there is a cylindrical screw chamber B with a suitably formed
spiral C on each side of the case with beaters E E revolving in à water space or
channel F similar in form to that in Fig 8 and there are two inlets leading from
the suction pipe to the open end of each cylindrical screw chamber B but with
a common outlet from the water space or channel F.
j
We would have it understood that the precise forms and arrangements of the
screw, screw chamber, beaters and water space or channel, may be varied as
required, so long as these parts are combined in such a manner as to adapt them
for working as above described in the different modifications of our Invention.,
Having now particularly described and ascertained the nature of our said
Invention and in what manner, the same is to be performed we declare that what
we claim, is
The combination of a suitably driven screw or screws and blades or beaters
revolving respectively in a screw chamber and a water space or channel fitted
between the suction pipe and the delivery pipe in pumps substantially as and for
the purpose described.
