JOHN E. SHUTT, OF GANADO, TEXAS.
PUMP.Specificationof Letters Patent.
Patented June 15, 1909.
Application filed March 31, 1908. Serial No. 424,398.
To all whom it may concern:
Be it known that I, JOHN E. Sumr, a citi-
zen of the United States, residing at Ganado,
in the county of Jackson and State of Texas,
5 have invented a new and useful Pump, of
which the following is a specification.
This invention relates to double acting
pumps for pumping water from deep wells,
and has for its object to provide a simple and
10 durable construction of pump of this char-
acter which will withstand the most severe
conditions of service, and which will be re-
liable and will continuously elevate a large
volume of water, and which can be readily
15 secured in place and removed.
The invention further has for its object to
provide an operating mechanism for a
double acting pump by means of which a
very long stroke will be obtained and the
2 operation carried on in a very efficient man-
ner.
The invention also has for its object cer-
tain improved details of construction by
means of which the operation of the parts
25 will be facilitated all as hereinafter set forth
and claimed.
Referring to the accompanying drawings,
Figure 1 is a view in elevation of a pumping
apparatus constructed in accordance with
30 this invention, and, also, showing broken
away and in vertical section, a portion of a
well casing containing the lower ends of the
plunger rods and their plungers. Fig. 2 is
a plan view showing the construction of one
35 of the rocker levers. Fig. 3 is an enlarged
detail view showing the means for automat-
ically oiling the pivotal connection of the
rocker arms and levers. Fig. 4 is an en-
larged detail view showing the lower end of
40 the upper plunger rod and plunger. Fig. 5
is an enlarged detail view showing the lower
end of the lower plunger rod and plunger.
Fig. 6 is an inverted plan view of the lower
plunger.
45 The mechanism may be used either with
an engine or with a wind-mill pump.
1 is the lower plunger rod adapted to be
connected at its upper end to the lower
end of the pump rod of a wind-mill or other
50 operating device. 2 is the hollow upper
plunger rod having its upper end connected
to a cross head 3. The lower plunger rod 1
is secured to a cross head 4 by bolts 5 and
extends down through and is movable in the
55 upper plunger rod 2.
Pivotally connected to the cross heads 3and 4 by links 6 and 7 are two rocking levers
8 and 9, mounted to rock upon a pin 10 hav-
ing its ends secured to the cross beams 11,
connected to the wind-mill frame, by means 60
of pairs of yokes 12 having hook ends 13
engaging beneath the cross beams 11 and
projecting through the strap 13', and bolted
thereto by nuts 14, thereby clamping the
ends of the pin 10 securely to the cross 65
beams 11. The rocker levers 8 and 9 are
each constructed with two members, as shown
in Fig. 2, each member having a central,
partly curved portion 15, mounted on the pin
10 and branch arms 16 extending from said 70
central portion 15 and uniting at their outer
ends to form sockets 17 in which are piv-
oted the outer ends of the links 6 and 7. The
rocker levers 8 and 9 have their branch arms
16 disposed on the central portion 15 in dif- 75
ferent planes from each other, whereby the
adjacent lower edge 18 of one of said branch
arms will be parallel to the adjacent upper
edge 19 of the other branch arm. The up-
per edge 20 of one of the branch arms of 80
each rocker lever, and the lower edge 21 of
the other branch arm of each lever taper
from the center to their outer ends.
The rocker lever 8, constructed as shown
and described, is located within the rocker 85
lever 9 to move therein. The rocker levers
made in this way are prevented from bind-
ing, and, as shown in Fig. 1, they come quite
close together.
When the rocker levers are at the other 90
end of their stroke or opened to the fullest
extent, the cross heads are pushed far apart,
making a very long stroke which gives a
similar long stroke to the plungers.
22 is a stuffing box in the cross head 3, 95
through which extends and moves the lower
plunger rod 1.
Means for oiling the pivotal connection of
the rocker levers and the links connecting
them with the cross head is provided as fol- 100
lows:-23 and 24 are the pins connecting the
rocker levers 8 and 9 with the links 6 and 7.
The pin 23 is provided with a slot 23' ex-
tending partly about said pin, and extending
into the link 7 is a pipe 25 having its lower 105
end opening into the hole in which the pin
23 is located. On the top of said pipe 25 is
an oil cup 26 distributing the oil to said pin.
The pin 23 is held in fixed position by a
screw 26' and in the lowest position of the 110
links 7 and rocker levers 8 the end of the slot
23' is out of alinement with the lower end ofNo. 924,697.
