AN IMPROVED PUMP
Year: 1885

page_text: We GILBERT MURRAY and ROBERT TURNLEY of Elvaston in the county of
Derby respectively Land Agent, and Mechanic do hereby declare the nature of
our invention for AN IMPROVED PUMP to be as follows:-
This invention has for its object the construction of an improved pump for
raising or forcing water or other liquid and is especially applicable for use in
wells. We arrange a rising main of suitable depth carrying at its upper end a
closed air chamber having stuffing boxes in which works the crank or other
actuating mechanism. I arrange a long plunger of wood or other material carrying
a piston at its upper end working in a chamber or.extension of the said rising
main, this main communicates with a syphon pipe having its shorter leg fitted
with a perforated bulb or end arranged to enter the well or liquid. The top of
the syphon communicates with the rising main through a chamber formed above
the bend of the syphon. The top, bottom and intermediate web of this chamber
form seatings for a plug valve attached to a chain, cord or like device passing
through a bell mouth above the said chamber and syphon.
The valve is slotted to receive pins which act as guides and stops.
When the plunger is worked and the valve pulled up this starts the syphon.
The liquid flows to the chamber below the syphon forming the "long leg" it
then ascends and passes to the chamber above the syphon into the air chamber
at the top of the rising main allowing liquid to enter the said air chamber and be
expelled through an outlet. If desired we may actuate the plunger by a direct
acting steam cylinder in place of by a crank,

page_text: We, GILBERT MURRAY and ROBERT TURNLEY of Elvaston in the County of
Derby Land Agent and Mechanic respectively, do hereby declare the nature of our
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 has for its object the construction of an improved pump for
raising or forcing water or other liquid and is especially applicable for use
in wells.
Referring to the accompanying sheet of drawings and to the figures and letters
of reference marked thereon.
Fig. 1. is a sectional side elevation of a forcing pump constructed according to.
our invention the rising main being broken for convenience.
Fig. 2 is a section of the head where the water or liquid is only to be raised and
not forced, in these views a rock shaft operates the plunger.
Fig. 3. is a sectional front elevation of the head for working the pump by power
or handle from a crank.
Fig. 4 transverse section on line a. - - b Fig. 1.
We arrange a rising main A of suitable length, and which may be constructed
in sections, carrying at its end a chamber B having stuffing boxes C in which
works the crank D, or other suitable actuating mechanism may be used. In Fig. 3
E is a flywheel or driving pulley as the case may be accordingly as the pump is
worked by hand or power; its connecting rod F is jointed to a long plunger G as
shewn in Fig. 3. by pin and shackle or other joint.
In Figures 1 and 2 we pass a rock shaft H through stuffing boxes in the sides
of the chamber B and cause a lever or crank arm I on the shaft H to engage with
a slot J in a vertically sliding rod K carrying at one end a cupped leather bucket
or piston L and jointed at its lower end to the plunger G as before; in this case
(Fig. 1) we make an air hole M in the head of the case B to allow of the upstroke
of the rod K and bucket or piston L; this plunger & may be advantageously made
of wood or other material may be used.
The rising main A communicates with a sypbon pipe having its shorter leg N
fitted with a perforated bulb or end N₁ arranged to enter the liquid or well. The
top of the syphon O communicates with the rising main A through a chamber P
formed above the bend of the syphon,
The top, bottom and intermediate webs of this chamber P form seatings for a
hollow plug Qin which are seated two valves R R¹ being discs with three vertical
webs S in which are formed ports T. One or both sides of the plug are slotted
out at U to get these valves into position. Pins or stops V are fitted passing
through the hollow plug Q to limit the upward play of the valves R in the plug.
We attach a chain cord or like device W passing through a bell mouth X above
the said chamber P and syphon so as to lift the plug Q when required for cleaning
renewal or repairs of itself or its valves; the latter may be of metal in one piece,
or the disc portion may be of leather, rubber or like material. Y is a plunger or
bucket jointed to the lower end of plunger G and working in the bottom of rising
main A.

page_text: When the plunger G and its bucket V make the upstroke the syphon is started
by the lifting of the valve R the liquid being so allowed to flow from the short to
the long leg O.
On the downstroke of the plunger G valve R is shut and and valve R¹ lifted
whereby the liquid in the long leg of the syphon is forced into the rising main A
through the valve R¹.
·
On the next upstroke the valve R will open, valve R¹ shut and the liquid again
flow through the syphon ready for the next downstroke.
The water or liquid ascends through the rising main owing to the plunger being
of lesser diameter than the main and in the case of Figure 1 is forced into head
chamber B and the air chamber Z and out through outlet Z₁ or in cases where
water or liquid is not to be forced to great heights the air vessel Z is dispensed
with and the liquid flows into chamber B and is forced through outlet Z as in
Figures 2 and 3.
If desired we may place a steam or other motor cylinder above the chamber B
and work the plunger G by direct action. The bell mouth X allows the ready
play of the chain for raising and lowering the plug Q and also forms a wide exit
for water in the syphon flowing to the well again when the plug Q is lifted.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed we declare that what
we claim is
First. In combination with a syphon supplying liquid to the rising main of a
pump a hollow removable plug such as Q fitted with valves, means for raising
or lowering such plug and a chamber such as P forming a seating for the plug
and also a conduit to the rising main, substantially as described.
Secondly. In combination with the syphon O, the removable plug valves R R¹
chamber P with its bell mouth X and delivery port, the rising main A plunger G
and chamber B substantially as described.
