I, JOHN SYMINGTON, Engineer, of 20, Buccleuch Street, Glasgow, do hereby declare
the nature of this invention to be as follows:-
This invention relates to pumping machinery and it has for its object to improve
the construction of such machinery.
The invention relates to that class of pumping machinery wherein the rising main
is constituted by hollow pump rods.
In carrying out the invention I prefer to use two sets of pumps so as to give a

double action and thereby produce a continuous flow of water.
rods of each set are formed of thin malleable iron or steel tubes. The upper section
of each set of tubes has a pivot pin or bearing arrangement secured to it to which a
forked lift rod is secured. Each lift rod is attached to a bell crank and the bell
cranks are secured together by means of a cross head or connecting rod so as to be
operated simultaneously from the same prime mover.
The upper section of each set passes through a stuffing box at one end of a receiver
and the receivers are connected together by a cross pipe or tube or a hollow bridge
which is secured in place at the top. of the mine shaft or other place. Connected
with the cross pipe or bridge is a discharge pipe.
If it is desired to force water up to a distance above the discharge pipe
aforesaid a pipe connection is coupled to the discharge pipe and led to the height
desired.
As each pump operates the upper tubular sections work in and out of the receivers
and deliver the water into the cross pipe or bridge from whence it is discharged or
forced into the discharge pipe and its connection.
The bell cranks are so arranged that when one pump is on the down stroke the
other pump is on the up stroke.
The invention can be applied under a modification to a single acting pump.

I, JOHN SYMINGTON, Engineer, of 20, Buccleuch Street, Glasgow, 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 pumping machinery and it has for its object to improve
the construction of such machinery.
The invention relates to that class of pumping machinery, such as described in the

page_text: Specification of my prior Patent No. 5287 of 1897, wherein the rising main is
constituted by hollow pump rods.
In carrying out the invention I prefer to use two sets of pumps so as to give a
double action and thereby produce a continuous flow of water. The hollow pump rods
of each set may be formed of thin malleable-iron or steel tubes.
And in order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings, whereon,
Fig. 1 is a front view and Fig. 2 a side view of part of a double acting mine-pump
constructed in accordance with my invention.
Fig. 3 shows a single acting pump.
As will be seen from the drawings of the double acting pump (Figs. 1 and 2) the
upper section a of each set of pump tubes has pivot pins 6 (or a bearing arrangement)
secured to it to which a forked lift rod c is secured. Each lift rod c is attached to a
bell crank d and the bell cranks are secured together by means of a cross head or
connecting rod e so as to be operated simultaneously from the same prime mover.
The upper section à of each set of pump tubes passes through a stuffing box gat
one end of a receiver h and the receivers are connected together by a cross pipe or
tube i or a hollow bridge, which is secured in place in any suitable manner at the
top of the mine shaft or other place. In Figs. 1 and 2 a cross beam j is shown as
supporting the cross pipe or bridge. Connected with the cross pipe or bridge is a
discharge pipe k.
If it is desired to force water up to a distance above the discharge pipe aforesaid a
pipe connection is coupled to the discharge pipe and led to the height desired. For
collieries it is found advantageous to have a pipe (Fig. 3) through which water can
be delivered for washing coal. A twoway valve m is fitted on the pipe and so
arranged that when necessary the water can be cut off from the pipe and delivered
to the discharge pipe k or vice versa.
As each pump operates the upper tubular sections work in and out of the receivers
and deliver the water into the cross pipe or bridge from whence it is discharged or
forced into the discharge pipe and its connection.
The bell cranks are so arranged that when one pump is on the down stroke the
other pump is on the up stroke.
In the case of a single acting pump as shown at Fig. 3, the cross pipe, has a blind
flange n on it. With this arrangement whenever it may be so desired, the pump
may be inade double-acting by fitting a second pump and pump tubes beside the
first and connecting the upper section of the pump tubes to the cross pipe i after
the removal of the blind flange n. In the case of a single acting pump of course only
one bell crank d and its lift rods are required.
The pump tubes are arranged to work between guiding and staying rollers o placed
at intervals in the pit shaft.
The hollow pump rods are preferably made of mild steel tubes having welded
flanges.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I consider novel and desire to claim is :-
Pumps of the class set forth having the parts constructed arranged and combined
together substantially as herein before described with reference to the drawings
annexed.
