BOSTOCK, of Rugeley, aforesaid, Plumber. "IMPROVEMENTS IN PUMPS."
In pumps as ordinarily constructed the end of the suction pipe or pipes by which
the water is drawn into the pump simply dips into the water, the end of the pipe
entering the water being of the same diameter as the other portions of the pipe
The result of this arrangement is that when the pump is worked the water in the
well or sinking is much disturbed, sand or gravel is raised into the pump to the
injury of the valves and bucket.
The first part of our Invention has for its object to provent sand or gravel rising
into the pump, and thereby to preserve the pump from the injury to which pumps.
as ordinarily constructed are hable by the action of the sand or gravel raised with
the water.
Instead of making the suction pipe of the pump terininate in the usual way we
attach to the bottom of the said suction pipe a semicircular pipe, the upper end of
which terminates in a hollow bulb pierced with a large number of small holes, the
said semicircular or turned up pipe constituting a prolongation of the suction pipe
The said turned up pipe and bulb we make by proference in two parts, connected
by flanges and screw bolts, or otherwise we make the semicircular or turned up pipe
in one piece, and the hollow pierced bulb in another piece. We do not however
limit ourselves to any particular method of manufacture
By the use of our Invention the water enters the suction pipe from a higher level
than usual, and being divided into a great number of very small streams little dis-
turbance of the water is produced. As the finer particles are taken away the largoi
particles form a filter around the rose or tube This part of our Invention is
applicable to all kinds of pumps.

page_text: The second part of our Invention consists in introducing into the suction pipes of
pumps a trap constructed in the following manner - -The said suction pipe at a
considerable height above the level of the water has a double bend, that is, the said
suction pipe at the part indicated turns down, and then turns up, the said part
having nearly the figure of the letter S turned from its vertical into a horizontal
position The bent part terininates in an an vessel, the pipe communicating direct
with the pump, entering the top of the an vessel, and descending to a point below
the level of the top bend in the suction pipe On working the pump the water
first uses over the first or highest bend, and falls into the lower bend, from which it
is drawn by the pump upwards By this improvement the water can be readily
raised forty-two feet from the surface of the water in the well, a greater height
than that to which it can be raised by.pumps of the ordinary construction

In pumps as ordinarily constructed the end of the suction pipe or pipes by which
the water is drawn into the pump simply dips into the water, the end of the pipe
entering the water being of the same diameter as the other portions of the pipe
The result of this arrangement is that when the pump is 'worked' the water in the
well or sinking is much disturbed, sand or gravel is raised into the pump to the
injury of the valves and bucket
1
The first part of our Invention has for its object to prevent sand or gravel rising
into the pump, and thereby to preserve the pump from the injury to which pumps
as ordinarily constructed are liable by the action of the sand or gravel raised with
the water
Instead of making the suction pipe of the pump terminate in the usual way wo
attach to the bottom of the said suction pipe a semicucular pipe, the upper end of
which terminates in a hollow bulb pierced with a large number of small holes, the
said semicircular or turned up pipe constituting a prolongation of the suction pipe
The said turned up pipe and bulb we make by preference in two parts, connected
by flanges and screw bolts or other wise We make the semicircular or turned up
pipe in one piece, and the hollow pierced bulb in another piece We do not however
limit ourselves to any particular method of manufacture.
By the use of this part of our Invention the water enters the suction pipe from a
higher level than usual, and being divided into a great number of very small
streams little disturbance of the water is produced As the fine particles are taken
away the large particles form a filter around the bulb rose or tube This part of
our Invention is applicable to all kinds of pumps
The second part of our Invention consists in introducing into the suction pipes of
pumps a trap constructed in the following manner -The said suction pipe at a
considerable height above the level of the water has a double bend, that is, the said
suction pipe at the part indicated turns down and then turns up, the said part
having nearly the figure of the letter S turned from its vertical into a horizontal
position The bent part terminates in an all vessel, the pipe communicating direct
with the pump entering the top of the air vessel, and descending to a point below
the level of the top bend in the suction pipe On working the pump the water
first rises over the first or highest bend, and falls into the lower bend, from which
it is drawn by the pump upwards By this improvement the water can be readily
raised forty-two feet from the surface of the water in the well, a greater height than
that to which it can be raised by pumps of the ordinary construction.

page_text: We will now describe with reference to the accompanying Drawing the manner
in which our Invention may be performed, the said Drawing representing partly in
section and partly in elevation an ordinary lifting pump with which our improve-
inents are combined.
a is the suction pipe of the pump, having at its bottom end the semicircular or
turned up pipe b, the said pipe 6 constituting a prolongation of the said suction pipe,
as represented The upper end of tho turned-up pipe b terminates in the hollow
perforated bulb or rose c The tuned up pipe band perforated bulb or rose c arc
made by preference in two parts, connected together by flanges and screw bolts at
d The semicncular or turned up pipe 6 is connected to the suction pipe a by
flanges and screw bolts at e By the use of the said turned up pipe b and pierced
or perforated bulb or rose c the advantages herein-before pointed out are secured.
The suction pipe a at a considerable height above the level of the water in the
well or sinking has a double bend f, g, made in it, the said double bend resembling
somewhat the letter S in a horizontal position The bent part 9 terminates in the
air vessel h, which is joined to the part g by flanges at i The pipe in connection
with the pump bairel enters the top of the air vessel h, and descends to a point
below the level of the top bend fin the suction pipe, as represented In the top of
the bend g is a valvo m opening upwards On working the pump the water flist
rises over the highest bend f, and falls into the lower bend g, from whence it passes
into the air vessel h, from which it is drawn through the pipe k to the pump bariel
1, the water drawn into the air vessel being prevented from returning into the bend
g by the valve m at the highest part of the said bend
Having now described the nature of our Invention, and the manner in which the
same is to be performed, we wish it to be understood that we claim as our Invention
of improvements in pumps,-
First Attaching to the bottom of the suction pipe or pipes of the pump a semi-
Cucular or turned up pipe terminating in a hollow piciced or perforated bulb or
rose, for the purpose and substantially as herein-before described and illustrated in
the accompanying Diawing
Secondly Placing in the course of the suction pipe or pipes of the pump, and at
a considerable height above the level of the water to be lifted, a tiap or pipe having
a double bend in combination with an au vessel, for the purpose and substantially
as herein-before described and illustrated in the accompanying Diawing
In witness whereof, I, the said Henry Bennet, have hereunto set my hand
and seal, this Second day of August, in the year of our Loid One thousand
eight hundred and seventy-seven
