FRANK OSKAR HANGAS, OF CHANNING, TEXAS, ASSIGNOR OF THREE-EIGHTHS TO
OTIS H. TWADDELL AND THREE-EIGHTHS TO SNEED H. TWADDELL, OF DALHART,
TEXAS. .M.
PUMP.Specification of Letters Patent. -Patented May 16, 1911.
Application filed May 14, 1908. Serial No. 432,771.To all whom it may concern:
Be it known that I, FRANK OSKAR KANGAS,
citizen of Finland, Russia, residing at
Channing, in the county of Hartley and
5 State of Texas, have invented certain new
and useful Improvements in Pumps, of
which the following is a specification, ref-
erence being had therein to the accompany-
ing drawing.
10 My invention relates to improvements in
pumps which move a long column of water
with each stroke but discharge a relatively
small quantity, and the objects are to econo-
mize power and improve the working of such.
15 pumps by counterbalancing that portion of
the water column which remains after each
discharge, and to provide means whereby the
length of the water column is maintained
even when there is some leakage of the
20 pump valves, the devices being adapted for
use in connection with drilled wells, or such
as have no space outside the well tube.
In the accompanying drawings, Figure 1
is a side elevation showing the main portions
25 of my apparatus in operative position. Fig.
2 is a like view illustrating a different con-
struction.
In these figures, A represents a well tube
having as usual at or near its lower end an
30 upwardly opening valve B capable of fully
closing the tube. The portion of the tube
just above the valve serves as a barrel or
cylinder in which works a plunger C, of any
approved construction, provided with an
35 upwardly opening valve D and having its
rod E extending upward beyond the upper
end of the tube and sliding in a suitable fixed
bearing F. The plunger is caused to recip-
rocate by means of a crank G of a power
40 shaft II driven by a wind, steam, explosion,
or other engine (not shown), the crank be-
ing connected to the plunger rod by a pit-
man I having a swiveled or hinged union
therewith. The crank shaft is further pro-
45 vided with a second preferably equally ec-
centric crank J upon which is supported a
counterweight K approximately equal in
weight to a body of water sufficient to fill
the tube A from the highest point reached
50 by the plunger to the point at which water
is discharged from the tube. This weight
is preferably made up of detachable parts K'
so that the total weight may be adjusted for
water columns of different weight.Water raised by the pump is discharged 55
through a conduit L into any suitable tank M.
Should there be any leakage at the valves
and should the pump be out of action for
some time, the water column sometimes sev-
eral hundred feet in length, might disappear 60
leaving the heavy weight unbalanced. To
avoid this result, a small pipe N leads from
the tank back into the tube and is provided
with a valve 0 which may be left open
slightly so that the level of the water in the 65
tube is always practically the same as in the
tank, and therefore the weight and the col-
umn always balance each other.
In Fig. 2 the column and plunger are
shown as counterbalanced by a weight P 70
suspended by a cable passing over a pulley
Q and attached at a'lower point to the plun-
ger rod R in such manner that weight tends
to draw the rod upward with material lat-
eral pull. This form counterbalances the 75
column, but in practical use it is a far less
desirable construction than that shown in
Fig. 1.
It is to be noted that my invention is ap-
plicable to pumps used in driven or drilled 80
wells, as well as in wells where access may be
had to the exterior of the tube, and that in
fact it is in such drilled wells, often from
two hundred to five hundred feet in depth,
that the use of the invention is of greatest 85
importance.
What I claim is:
1. The combination with a pump tube
having a valve at its lower end and a plun-
ger working in the tube above the valve, of 90
means for counterbalancing the weight of
the body of the water column in said tube,
and automatic means for maintaining a con-
stant amount of water in the tube to balance
the counterweight. - 95
2. The combination with a pump tube, of
a plunger in said tube, means for recipro-
cating the plunger, a counterweight ar-
ranged for balancing the plunger and the
main body of the water in the tube, a tank, a 100
conduit leading from the upper part of the
tube to said tank, and a small conduit lead-
ing from the tank into said tube at a point
below the discharge point whereby the water
in the tube being kept at the same height, 105
the counterweight remains balanced al-
though the lower valve should leak.
3. The combination with a pump tube992,358.
