5 Claims. (Cl. 74—522.5)
This invention relates to new and useful im
provements in well pumping equipment.
This application is ?led as a divisional applica
tion of my original co-pen-ding application ?led
December 15, 1933, Serial No. 702,548.
One object of the invention is to provide pump
ing equipment wherein an improved swing is em
ployed for transmitting motion from a pumping
power to a rod line.
An important object of the invention is to pro
vide an improved swing beam for transmitting
motion from a pumping power to a rod line which
is arranged so as to reduce rod line vibration to a
minimum, and which is so constructed that trans
mission ratios may be set up for controlling the
Figure 6 is a plan view (details omitted) show
ing the swing connected with a pumping power
and rod line,
Figure 7 is a view, partly in section and partly
in elevation of a modi?ed form of the swing, and
Figure 8 is a transverse, vertical sectional View,
taken on the line 8—8 of Figure 7.
In the drawings, the numeral ll] designates a
pumping power (Figure 6) which may be of any
suitable type. The usual‘pitman II has one end
pivoted to the eccentric ring [2 of said power. It
is customary to provide a shelf or rail l3 on which
the pitman may rest when it is disconnected from
the swing. The loop M at the other end of the
pitman is connected to a hook 15 carried by a
swing beam l6 which is mounted to swing on a
length of the stroke or travel of the rod line.
Another object of the invention is to provide an
post ll.
improved swing beam wherein the supporting
The hook I5 is attached to a bearing collar l8
bearing, as well as the bearings to which the pit
mounted in the beam (Figures 1, 4 and 5’) . A sec
ond bearing collar l9 also mounted in the beam is H
connected through a suitable “knock-oil” or dis
20 man and rod line are connected are constructed so
as to insure constant lubrication and to withstand
heavy loads, as well as being substantially dust
and water proof.
A further object of the invention is to provide
25 an improved swing which is capable of pumping
two wells at the same time and which is so de
signed that the well to be pumped or operated can
be located at most any angle with relation to the
connecting device 20 with a rod line 2|. The rod
line has connection with the usual pump jack
(not shown). The pump rods in the well exert a
pull on the rod line H which pull is applied to the
parts attached thereto and transmitted back to
the power [0. With the hook-off 2!] connecting
the rod line with the swing, the pull exerted by
pumping power, thereby making it unnecessary , the power l0 through the pitman is transmitted to
the rod line. With the hook-01f device disen- U O
for said well to be in direct line with said power.
Still another object of the invention is to pro
vide an improved swing which is adapted to be
connected with the usual pitman of a pumping
power and operated by a push and pull motion,
the swing having means whereby a suitable
“knock-off” or disconnecting device may be con
nected therewith.
A construction designed to carry out the in
vention will be hereinafter described, together
40 with other features of the invention.
The invention will be more readily understood
from a reading of the following speci?cation and
by reference to the accompanying drawings, in
which an example of the invention is shown, and
Figure l is a plan view of a swing beam con
structed in accordance with the invention,

bearing and support, and taken on the line 3—3

gaged, themotion from the pumping power will
not be transmitted to the rod line 2!. It is noted
that the pumping power and hook-off device 20
form no part of the present invention, the latter
being fully described in our co-pending applica a: bi
tion ?led December 15, 1933, Serial No. 702,548.
In fact it would be possible to eliminate the hook
off entirely and connect the rod line 2| directly
to the bearing IS.
The swing beam i6 is formed of top and bottom 40
channels 22 and 23, the upper one being inverted
so that their ?anges are inwardly opposed and
spaced apart. . These channels are provided with
bolt holes 24 and 25. The bearing I8 is secured
by bolts through the bolt holes 24 and this bearing as 5
includes a bearing cap 26 which is fastened to the
top channel 22 of the beam by bolts 26' which pass
through the openings 26 in said channel. A bear
ing step TI is secured to the lower channel in a
similar way by bolts 21’ which pass through the
bolt holes 24 in said lower channel. The bearing
18 is completed by a central collar [8’ located
and con?ned between the cap 26 and step 21.
This collar has a central well 28 which receives a
pivot stud 29 depending from the. cap. A stud 30
depends from the collar into a well 3| in the step.
The studs are hollow and the wells co-acting
therewith will hold ample quantities of lubricant.
Any suitable means for supplying lubricant to the
wells may be employed.
As is clearly shown in Figure 1, the bolt holes
24 are spaced substantially throughout the length
of the channel bars 22 and 23.
Thus, by remov
and the rod line which is coupled thereto, a num
ber of operations may be carried out. When the 5
standing valves become clogged with sand, the
stroke can be lengthened to. strike the‘ valves to
gether and jar loose the sand, or the top of a cor

roded working barrel may be cleaned by changing
moved longitudinally of the channel bars. Thus,

the stroke. The swing may be worked at an angle 10
the beam which is the post I‘! may be varied.
The additional spaced bolt holes 24 permit the
bearing to be fastened in the beam in any‘posi
15 tion therealong. When the position of the bear
ing l8 which is connected with the pumpingv pow-'
er I0 is varied along the length of said beam, it
will be obvious that the swing of the beam will be
varied, whereby the movement or stroke of the
rod line 2! will be varied. Therefore, by properly
adjusting the bearing l8 within the beam, the
desired‘r'lengthv of stroke of the rod'line may be
The bearing [9 to which the rod line 2'! is at
tached includes a cap 82 which is secured totthe
upper channel 22 by bolts 33 which extend
through the bolt holes 25'. A step 34Iis fastened
to the lower channel 23 by bolts 35 which pass
through the bolt holes 25 in this lower channel.
A bearing collar i9’ is located-between the cap
and step and is con?ned therein by a hollow stud
31 which depends from they cap132 into the cen
tral Well 38 of the collar.

ment on the beam l6, whereby the bearing I 8
may be shifted to amplify or reduce the swing of
said beam and the travel of the connecting rod
The collar has a de
and/more than one well can be operated thereby.
Because of the easy swing a smaller rod line may
be employed. Two wells may be pumped by the
same swing, one with a long stroke and the other
with a short stroke. The beam l6 may be mount
ed high. above the ground or close to it, as the
case may be.
When the pumping is to be stopped, the opera
tor merely has to wait until the beam swings to
the right (Figure 1) to complete its pull stroke,
and then uncoupletherod line 27!, by disengaging
the hook-oif. device 201
The beam‘v I6; may con
tinue to swing‘; however, where the hook I5 is
used, the pitmanrwillpushits loop 14 out of said
hook, thus ridingv on-the shelf l3' and. save the
swingfrom unnecessary‘ wear.
While the connection to the pitman l l is shown
by meansof the hook I5 and loop' Ill, whereby the
parts are automatically disconnected it is to be
understood that any desirable connection be- .
tween the pitman and bearing I8 may be made,
and the automatic disconnecting. feature may be
pending hollow stud 39 depending into the well
40 of the step 34; A rod Mbywhich connection
may be made withthe bearing: l9 extends trans
versely through the collar 19’. Thus, it is seen
It is pointed out that‘ because of the. proximity
of ‘the-swing beam iii to the pumping power ID,
the amplitude'of swing‘ of- said. beam is not as
great,.for a given rod line stroke, as Where the
that the bearings l8 and I9 are similar in‘con
siderable' distance from the pumping power,
swing‘beam (usually vertical) is located at a con
The'bearing collars l8’ and. i9’ have ?anged
bearing contacts with their caps.andfsteps,-which
contacts may be suitably packed whereby escape
which is thepresent oil' ?eldpractice. By short
of the lubricant from the wells of the bearings is
duced. This not only cuts down vibration and
side whip, butreduces wear of the parts and
reduced to a minimum. The bearing contacts are
large and the oil baths make for adequate lubri
cation and cool journals. Further, it is noted that
the packing at the contacts not. only prevents es
cape of lubricant but also makes the bearings
substantially dust and water proof.
sup'portingthe inner end'of the beam l6‘ on
I‘! so that said‘ beam may undergo a
swinging movement, a bearing member is- pro
vided. This member includes abearing step 43
fastened‘to the post by U-bolts144 (Figure 3).
hub 45~is journaled betweenthe step 43 and a
v! in
cap 46 whichis held on the post by U-bolts-ill.
The hub is formed with brackets 48iwhich extend
contiguous toithe channels 22 and‘ 23 of‘ithe beam,
being secured to said channels by bolts 49. This
60 bearing member is of the oil bath type and is
similar to the bearings “land IS. The ‘step has
a well d3’ which receives a hollow stud M’ de
pending from the hub‘. The upper‘ end of. the
‘step ?ts in the bottom of the hub around the
stud. The upper end of thehub engageszin the
bottom of'the cap 46 around a stud 46' which de
pends into a well 45' in the hub. The joints’may
be suitably packed and lubricating oil maybe
constantly fed to the wells 45’ and d3’. 'I‘hebear~
ing members are large and adequate to. support
the beam.
From the above, it will be. seen that a most
rigid swing beam is had. All bearings. are pro
vided with‘ an oil bath and are substantiallywater
and dust proof.- Becauseeofvthe- bearing adjust
ening the arc of the beam travel, lateral move~
ment or side play in the post. H. is. greatly re
makes" for an 1 easy operation.
In Figures '7 and 8, another means for adjust
ing the'collar bearing 18 is shown. The cap 26' is
arranged to slide longitudinally of the beam IE
on one side of a-track 50; while the step 21 is
mounted to slide on one side of a track 5|. A 50
bottom worm screw 52 is journaled in hangers 53
and threaded through an ear 54> onthe adjacent
side of the step 21. This screw has its head pro
jecting from the outer; end of the'beam'. By turn
ing the screw 52 the co1lar'l8-is adjusted longi- 1
tudinally of the beam. Any other form of ad
justment may be used.
