cient apparatus for pumping wells wherein the
lli use of sucker rod equipment is ineiilclent, costly
and not infrequently impossible.
' A'iurther object is to provide an apparatus of
the character described which utilizes the in

`and increase production.
' A further ,object of the invention is to eliminate
the use of sucker rods in well pumping equipment.
With the above and other objects in view the
w invention consists in the ‘novel- combination of
parts hereinafter described, illustrated in the
accompanying drawing, and set forth in the
claims hereto appended, it being understood that
various changes in form, proportion, size and

This step may be accomplished by alternately
applying to the tops of said liquid columns a force
from alternately actuated power plungers or rams
whereby to depress one column and raise `the
other and vice versa as aforesaid.
Inasmuch as the forces of equilibrium of the
two liquid columns function in the pumping op
eration; but a relatively small «power increment is
required to cause theliquid columns, to flow
from the top of the well.

In carrying out one embodiment of the present
45" invention, independent liquid columns capable
4of cou'nterhalancing> one another are created in
the well to be pumped either by providing parti
tioned or divided pipe lines or by utilizing inde
pendent pipe lines within the well casing or by
50 any suitable means.' Next, the coliunns are in
. teractively connected so that a counterbalancing
cient length/to‘ provide the plunger stroke desired.
The pipe line 3A terminates in the casing or> bar
rel 8. The plunger barrel 'l is positioned and
secured oil-center, Figure 2, in the ,casing 8 for
the purpose of accommodating, in small bore ap
paratus, the several valved ports later described. _ .
The lower end of the casing 8 is disclosed as at
9 with relation'to the plunger barrel l.
Within theplunger barrel ‘l is fixed the par
tition, I0 through and in which the tubular
plunger rod Il is slidably mounted. The upper
end of the rod Il is provided with the piston or
plunger head I2 operating in the upper portion 50
of the barrel 1 against the liquid column 6, there
being an opening I3 through the plunger l2 to the ~
the liquid in said columnsis interactively applied » bore of the plunger rod l I which opening is con
. iorce'derived from the hydrostatic equilibrium of
- from one to the other of the columns. This
_ l5 procedure creates `substantially counterbalanced v
trolled bythe upwardly opening check valve |14.
Atfits lower end and within the extension I5 55
oi' the plunger barrel 1, the extension I! being
oi such 'bore as to provide the ratios oi’ plunger
I 'head areas requisite or desired, the tubular rod
or plunger II constitutes or carries the plunger
head I8. Port openings I1 communicate with the
bore Il controlled by the check valve I4 in plung
er head I2. 'I'he extension or'plunger barrel I5 is
providedv with the liquid inlet opening I3 com
municating'with the well supply and controlled
by the inwardly opening check valve 20 and the
outlet openings 2Ir communicating with the liquid
coiumn 4 which Ireelysurrounds the plunger bar
rels 1 and I5. 'nie outlet openings 2I are con~
trolled by the outwardly opening check valves 22.
15 Below the partition _I3 the plunger barrel is pro
vided with the inlet openings 23 forming a sealed
passage through the liquid column 4 and com
municating with the well liquid supply, admission
oi which to the plunger barrel is controlled by the
20 inwardly opening check valves 24. Above the
partition III and below the plunger head I 2, when
the latter is in its lowermost stroke position, the
plunger barrel is provided with the openings or
ports 25 freely permitting the liquid of the liquid
25 column 4 to have inlet and outlet flow relative
to the movement o! the plunger head I2 in rela
tion to the ilxed partition I0.
The tops of the pipe lines 3 and 5 forming the
‘ liquid -columns 4 and 6 are closed as at 26 and‘21
30 with the exception of the vent valves 23 and 23
and. the pipe line connections 30 and 3l for con
nection of the liquid column actuating power
source. In simple form, a power operated plung
er or ram 32 is connected with the upper end of
35 line 3 and a similar -power unit 33 is connected to
the upper end of line l. These power units are
synchronously driven by any suitable means of
power application not shown. The power units 32
and 33 are provided with the outlets 34 and 35
40 through which liquid ilows or ispumped from the
well and by means of which the entire system
may be primed or charged with liquid.
'I‘hat portion of the plunger barrel below the
ilxed portion I3 is divided by the plunger head
Il into the chambers A and B whereby the appa
ratus-is of -the double action type> wherein dis
charge of the liquid to be pumped occurs on each
stroke oi the piston.
Operation is as follows:
during the upstroke oi’ the plunger C, liquid from
well supply enters chamber B through the inlet
valved port I9.
'I'he pumping power increment is now applied
to the ram 33 causing the liquid therein to ilow
into the column 6 whereupon' the plunger C is
caused to make .the down stroke. During this
down stroke the liquid oi’ column 4, caused by the
ram 32 to iiow through the ports 2_5 to raise the
plunger C, is now caused by the ram 33 to ilow
out through the ports 25 into the liquid column 4
and in addition causes the liquid in the chamber
B, closed to the well supply by the check valve20, to flow through the outwardly opening check
valves 22 into the column 4. Upon the initial up
ilow of the liquid in column 4, the ram 32 is re
tracted to the position shown thereby exposing
the outlet 34 through which the stroke volume of
chamber B flows from the well. 'I'he movements
described constitute a pumping cycle continu 20
ance of which will pump the well.
It will now be apparent that the plunger’en-f
semble C is interactive between the lower “ends”
of the liquid columns 4 and 6 and exercises from
one liquid column to the other the forces of hy 25
drostatic equilibrium and in addition exerts upon
either liquid column, when stationary or while.
moving, any force applied to the other, while con
currently maintaining-the independence of the
liquid columns.v
It should be noted that the stroke oi' the plung
er ensemble C may be determined and regulated
by the stroke of the rams 34 and 35.
The embodiment of the invention shown in
Figure 4 operates under counterbalanced liquid
columns E and F having pressure applied there
to alternately in the same manner as in the pre
viously described form of the invention. Thel
plunger head 40 at the top of the plunger 4I is
exposed to the lower end of column F whereas the 40
lower vside of said plunger head is exposed
through the openings“ to the other column E
whereby the plunger is eiIective to transmit the
interactive force of said columns from one to the
other thereof while maintaining said columns 1n 45
depen'dent of one another.
The plunger barrel 43 in which the plunger 4I
operates has a valved intakeopening 44, com
municating with the supply of liquid inthe well.
