Improvements in the Construction of Deep Well Pumps.
We JOHN KILNER and THOMAS WILLIAM MATTHEWS both of Imperial Iron
Works Renshaw Street, West Gorton near Manchester in the County of Lancaster
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:-
This invention relates to the construction of pumps to be used in deep wells or
borings, such as artesian wells, and other similar wells where the working barrel is
placed at or near the bottom of the well or tube the objects of the invention being to
increase the efficiency of the pump and to reduce the strain upon the pump rod.
The nature of our said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the annexed sheet of drawings and the following explanation thereof.
Fig. 1 on the drawing represents a vertical section of the working barrel and lower
portion of the tube of a deep well pump showing the application of our invention.
thereto.
Fig. 2 is a plan view of the clack valve and
Fig. 3 a plan view of the pump bucket.
The principal feature of novelty in our invention consists in placing the working
barrel of the pump at the extreme lower end of the tube and placing the clack valve
above, instead of below the working barrel.
a represents a portion of the lower end of the well tube and is the working barrel,
d is the pump rod, e the pump bucket and the clack valve the latter being of course
a fixture and the pump rod dworking up and down through the central boss fx thereof.
We may here state that the pump bucket and clack valve may be made of any
other suitable form but for the purposes of our invention and to obtain the maximum
amount of effective lift of water with a given diameter of working barrel we prefer to
make them in the form shown on the drawings.
The valve of the pump bucket e we make in the form of a ring ex and to limit its
action we key onto the pump rod above it a guard g.
The clack of the valve we also make in the form of a ring f**, and we fix above
the same a guard or check ring which is carried by a bridge piece i the central
boss ix of which (as well as that of the valve f) is bored so as to allow the pump rod d
to work freely through it.
We prefer also to perforate the lower part of the working barrel & with holes kand
to fix in the extreme lower end thereof a ring for the purpose of preventing the
pump bucket from falling out in the event of the breakage of the pump rod or
its cotter.
By the above construction and arrangement of clack valve and pump bucket we are
enabled to work the pumps much quicker than usual and to obtain a greatly increased
delivery with a given diameter of working barrel, and the pump never becomes choked
with sand or other solid matter accumulating between the top of the clack valve and
the bottom of the bucket as frequently occurs with pumps of the ordinary
construction.
Having now 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
as our improvements in the construction of deep well pumps is
The combination substantially as hereinbefore described and illustrated of a working

below the same as usual) and the pump rod working freely through the centre of the
clack valve.
