WILLIAM FAWCETT of Burton Salmon in the County of York, Gentleman, and
ARTHUR THOMLINSON of Darrington in the County of York, Engineer, do hereby
declare the nature of our invention for IMPROVEMENTS IN THE CONSTRUCTION AND
MANUFACTURE OF PUMP BUCKETS, to be as follows:-
In the case of an ordinary force pump as an illustration-we make the plunger,
or sucker, or, bucket hollow, with one or more inlets in both the upper and lower
surfaces to admit the water the bucket being fitted with one or more double seated
valves, by which means the valves open to admit the water on each side alternately,
according to the direction of the stroke, and close again by the succee.ling stroke
in the opposite direction the water so admitted to the bucket, being discharged by
means of one or more pipes attached to the end or ends of the bucket.

Improvements in the Construction and Manufacture of
Pump Buckets.
We WILLIAM FAWCETT of Burton Salmon in the County of York, Gentleman,
and ARTHUR THOMLINSON of Darrington in the County of York, Engineer do
hereby declare the nature of our invention for IMPROVEMENTS IN THE CONSTRUCTION
AND MANUFACTURE OF PUMP BUCKETS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, that is to say :-
Our invention of improvements in the construction and manufacture of pump
buckets has for its object, to construct a pump of simple formation and few parts,
and that shall discharge the liquid through its tubular pumprod. It may be used
for either a single or double action pump.
And in order that our invention may be clearly defined and understood we
annex a sheet of drawings in which the same letters of reference indicate the same
parts in any of the figures.
Fig. 1, is a sectional elevation of a pump fitted with our improved bucket.
Fig. 2, shows the adaptation of ball valves.
Fig. 3, elevation of complete bucket.
In carrying our invention into practice, in the construction of a double acting
force pump as illustrated in Fig. 1, of the drawings,
A is the cylinder or working barrel of the pump, which is shown as secured to
the framework by the bolts or screws B-C is the hollow pump rod, attached
to the bucket D, and passing through an ordinary gland or stuffing box E, on the
cylinder cover F, G is the suction pipe leading down into the well and communi-
cating with the cylinder A, either through the inlet valve H to the underside of
the bucket, or through the valve H and the waterway I to the top side of the
bucket.
When the bucket is rising water is drawn into the cylinder through the valve H,
and when the bucket descends water is drawn through the valve H' and the
passage I into the upper side of the cylinder.
Instead of clock valves as shown in Fig. 1 we may use ball valves as shown
in Fig. 2.
The bucket is constructed in the following manner, (its outward configuration
being shown in Fig. 3, and a section in Fig. 1.)—
There are two entrances to the interior of the bucket, one marked J, through
the bottom plate, the other K, through the top is covered by the archway L;
between K and J which are prepared with seatings, is placed a ball valve M, which
when the pump is in action, alternately closed the said entrances.
The two side pipes N conduct the water to the tubular pump rod C, through
which it is conveyed to any desired place.
O is an elastic packing, set up by the ring P and adjusting screws Q not shown
in this Fig. R, is a bottom plate.

page_text: The action is as follows-when the tubular pump rod with the bucket is raised
by any suitable means, and drawn upwards in the cylinder, water is drawn through
the valve H into the lower part of the cylinder which is filled by the time the
bucket reaches the top; at the commencement of the downstroke the valve H
closes and the water forces up the ball M and closing the entrance K, makes its
way up the passages N, and into the tubular rod C.
During the downward movement of the bucket just described, water is drawn
through the valve H¹, and fills the upper part of the cylinder.-When the bucket
again rises, the water above the bucket is prevented returning by the closing of
the valve H, and is forced through the archway L and the opening K (the ball
being now at its lowest position and closing the opening J) into the passages N, N,
and so up the tubular rod. These movements and actions are constantly repeated
during the working of the pump and thus a constant stream of water is delivered
from the top of the pump rod or through any attachment fixed thereto.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is or may be carried into practical effect,
we declare that what we claim is :-
1st. The construction and manufacture of pump buckets, arranged to discharge
the liquid through the hollow pump rod for the purpose specified and substantially
as herein described and illustrated.
2nd. A pump bucket constructed with two inlets J, and L, passages N, leading
to the tubular pump rod C, valve M to close the two ports L and J alternately, for
the purpose specified and substantially as shown.
