PROVISIONAL SPECIFICATION.
Improvements in Artesian Well and like Pumping Apparatus.
We, JOHN CHARLES PUSILL and HARRY GEORGE FEATHERBY, both of 272,
Moston Lane, Manchester, Engineers, do hereby declare the nature of our said
invention to be as follows:
Our said invention consists of a new or improved pump for raising stone, sand
or other matter removed in the sinking of artesian wells, and our invention has
for its object to enable a greater volume or bulk of matter to be raised, with
greater expediency than is possible with existing modes.
In accordance with our invention we employ a cylindrical casing or tube of
metal and in the lower end thereof we provide a clack valve-box, sustained in
position by a rod or spindle which passes up centrally through the casing afore-
said to a point above the casing where it is sustained by a cross-head and tapered
cottar pin. Said valve box is slightly tapered on its exterior and formed with a
slight shoulder and the mouth of the casing into which it fits and against which
the shoulder abuts is also tapered, so that when the valve-box is placed in posi-
tion and fixed by the tapered cottar it is caused to fit in, and close the casing end.
Within the said casing also is a pump bucket or piston, with rubber or like valves,
and sustained concentrically in the casing by a set of rods which extend upwards
and through the top end of the casing to a point beyond the extremity of the
central rod aforesaid, and are there joined together by a suitable bridge-piece and
stay.
The operation is as follows:-The apparatus being lowered into the well by.
means of a (wire) rope secured to the cross-bar of the pump bucket rods, the
weight of the casing causes the pump-bucket or piston to lie at the top end.
Immediately the debris is reached, and the casing is supported, the pump-
bucket sinks to the lower part of the casing, any water previously within the
casing and beneath the bucket making its escape through the valvular openings
in the bucket. When fully lowered, the pump bucket is then quickly hoisted
up, and in consequence of the vacuum produced, the debris immediately rushes
through the aforesaid valve box in the lower end of the casing and follows the
pump bucket.
By repeating such operation 2 or 3 times the casing becomes filled, and when
filled the apparatus is then hauled up to the surface and the clack valves close
under the weight of matter above them.
From the jib or head gear from which the rope is suspended the apparatus is
swung over a truck or tank. The tapered cottar in the clack-box rod is then
removed, and the clack box allowed to retire out of the casing to an extent which
permits the contents of the casing to fall out, and be dislodged into the tank. For
the next filling of the pump the clack box is replaced and fixed by the cottar,
and the apparatus is again lowered into the well. The extent to which the clack-
box can retire, out of the casing is determined by the length of the central rod,

page_text: the top end of which is formed with a collar or knob which drops on to the
bridge-piece beneath.
To cushion the impact between the said knob and bridge-piece also between
the pump bucket and clack-box or pump bucket and the bridge-piece of the
central rod above, we provide washers of "dermatine'
like character.
or other substances of a
"feather"
The lower end of the casing is cut away in parts to allow of the debris to readily
flow into the casing, and to ensure of the clack-box being properly adjusted or
set in relation to such cut away parts, we provide the central rod with a
or key-way, which engages with the keyway, or feather on the bridge-piece.

Improvements in Artesian Well and like Pumping Apparatus.
We, JOHN CHARLES PUSILL and HARRY GEORGE FEATHERBY, both late of
272, Moston Lane, Manchester, and now of Bleak House, Gillingham, Kent,
Engineers, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement;-
-
Our said invention consists of a new or improved pump for raising stone, sand,
or other matter removed in the sinking of artesian wells, and has for its object
to enable a greater volume or bulk of matter to be raised, with greater expediency,
than is possible with existing apparati used for the purpose.
In accordance with our invention, we employ a cylindrical casing or tube of
metal, and in the lower end thereof we provide a clack valve-box, sustained in
position by a rod or spindle which passes up centrally through the casing afore-
said to a point above the casing, where it is sustained by a cross-head and tapered
cottar pin. Said valve box is slightly tapered on its exterior and formed with
a slight shoulder, and the mouth of the casing into which it fits, and against
which the shoulder abuts, is also tapered, so that when the valve-box is placed
in position, and fixed by the tapered cottar, it is caused to fit in, and close the
casing end.
Also within the said casing is a pump bucket or piston with rubber or like
valves, sustained concentrically in the casing by a set of rods which extend up-
wards and through the top end of the casing to a point beyond the extremity
of the central rod aforesaid, where they are joined together by a suitable bridge-
piece and stay.
The action is as follows:-The apparatus being lowered into the well by means
of a rope secured to the bridge piece of the pump bucket rods, the weight of the
casing causes the pump-bucket or piston to lie at the top end. Immediately the
debris is reached, and the casing is supported, the pump bucket sinks to the lower
part of the casing, any water previously within the casing and beneath the bucket
making its escape through the valvular openings in the bucket. When fully
lowered, the pump bucket is then quickly hoisted up and in consequence of the
vacuum produced, the debris immediately rushes through the aforesaid valve box
in the lower end of the casing and follows the pump bucket.
By repeating such operation 2 or 3 times the casing becomes filled, and when

page_text: filled the apparatus is then hauled up to the surface, and the clack valves close
under the weight of matter above them. From the "jib," or head gear, from
which the rope is suspended the apparatus is swung over a truck or tank. The
tapered cottar in the clack-box rod is then removed, and the clack box allowed
to retire out of the casing to an extent which permits the contents of the casing to
fall out, and be dislodged into the tank. For the next filling of the pump the
clack box is replaced, and fixed by the cottar, and the apparatus is again lowered
into the well.
In order that our said invention may be more readily understood and carried
into practical effect we have hereunto annexed a sheet of drawings and will now
proceed to describe the same with the various figures and letters of reference
marked thereon.
Fig. 1 is an exterior view, and Fig. 2 a longitudinal section of our improved
pumping apparatus. Fig. 3 is a transverse section on line a-b, and Fig. 4 a
transverse section on line c-d.
(A) is the casing or body of the pump about 10 feet long and 2 feet diameter,
or other proportionate length and width to suit the size of boring.
(B) is the piston fitted with rubber valves (C), and sustained and operated
within the casing (A) by rods (1)), which pass out through the upper open end of
the casing (A) and are joined to each other as shewn, and by the cross-bar (D¹).
(E) is the clack valve-box, and (F) the clack valves.
Such valve-box is slightly tapered, or stepped on its exterior, and thereby
designed to fit tightly in, or against, the lower end of the casing (A) as illus-
trated under the adjustment of rod (G) which passes up centrally through the
piston (B), and within the casing (A), to a point above the bridge or cross-bar (H),
at the top of the casing (A), where it is slotted and fitted with a wedge-like
cottar (I), which serves to give the desired "nip" between casing and valve-box.
To prevent the rod twisting we provide a feather or long key (G) engaging with
key way in cross-bar (H).
The rope for raising, lowering and operating the pump is attached to yoke (D2).
With the pump casing in a state of rest at the bottom of the boring the several
parts occupy the position shewn in Fig. 2; any water, silt, sand, etc., in the
boring, and into which the pump has been lowered, having found its way into
the casing through valves (F), under the weight or fall of the casing (A), and
through valves (C), under the weight or fall of piston (B).
In proceeding to fill or charge the casing with debris, the piston (B) is raised
to the top end of the casing, which latter owing to its weight remains stationary,
thus drawing in a charge of sand, etc., beneath and displacing the water above
through the top end of the casing. To fully charge the casing the piston is lowered
and raised 2 or 3 times. When so filled the whole apparatus is then raised, the
charge being effectively retained by the valves (F).
After
When raised to the surface the apparatus is swung over a truck, or tank, the
cottar (I) removed, and the valve-box (E) allowed to drop out of the lower end
of the casing (A), and discharge the water, sand, etc., into the tank.
emptying the casing the valve box is replaced, the cottar (I) put into position
again, and the whole apparatus again lowered, until the casing (A) again reaches
the bottom of the boring, receives a further charge, and is again lifted and
emptied, and so on, continuously.
To limit the movement of piston (B), and cushion the contact between it and
the cross-bar (H) each time the piston is raised, we provide the tubular exten-
sion (J), and washer or facing of packing material (K), such as
« dermatine," also
to cushion the contact between said piston and the top of the valve box (E), we
provide similar packing (L). The piston (1) is, by preference, an easy
fit, but may be fitted with packing rings if desired.
All the parts are made in a simple form, and easily renewable in case of
breakage.
To permit of the ready flow of debris into the apparatus the bottom edge or

page_text: part of valve box (E) is cut away as illustrated, or provided with legs on which
to stand.
Having thus particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In apparatus for lifting debris from artesian wells and the like, the use of a
pump casing, fitted with removable valve-box, valvular piston or pump bucket,
rods and cottar, to operate said piston, and adjust said valve box, and all mounted
and operating substantially as herein set forth, and illustrated on the accom-
panying drawings.
