Application April 21, 1937, Serial No. 138,182 .
15 Claims.
This invention is broadly a connector for use
in attaching a well pump polish rod to an operat
ing structure, such for instance as the working
beamof a deep well pump.
More especially the invention is a pump rod
adjuster and valve spacer.
Deep well pumps commonly involve a standing
valve and a working valve and it is very often
necessary or desirable to change the distal rela
10 tion of the valves, and it has been proposed to
accomplish this change by axial shift of the polish
rod as to the operating pump beam.
An object of the present invention is to provide
an extremely simple, very substantial and highly
15 effective connector of this class which is char
acterized by ease of adjustment to readily pro
vide for the desired relational change of the
spatial distance between the valves. A further
object is to provide for an angular adjustment
of the polish rod, and its suspended associated
2O pump parts so as to vary the working zones of
contact from time to time to distribute the wear
of the engaging surfaces.
An additional object of the invention is to pro
vide for the positive and ready angular adjust
25
ment of the rod and its pendant parts and to
(Cl. 255-18)
head being provided with stop latches ‘I, or other
suitable means, to prevent accidental dislodg
ment of the links from the body 6.
Concentrically swivelled in the head or body 6
is a barrel 8 having‘ a top rim 9 seating on an
anti-friction ball bearing 10 in the body; this
being of generally cylindrical form. The barrel
8 has a reduced, ?at-sided portion 8a extending
below the bottom of the body 6 to removably
receive a transverse handle H which is held in 10
place by a nut l2 screwed onto the externally
threaded end of the barrel 8.
The body _6 is provided with means whereby it
may be locked to the barrel 8 against relative
rotation except for intentional adjustment of the 15
barrel in the body 6. As here shown the body 6
is provided with a lateral or radial pocket l3
having» transverse mouth slots l4 and opening to
the body bore in which the barrel 8 is turnable.
Fig. 2 shows a bolt of one type in detail as work
20
ing in and passing through a bearing ring l6
against which rests an expansion spring I‘! react
ing against a shoulder of the bolt l 5a so that this
is normally pressed inward and is stopped by its
cross pin 15*’ engaging in slots I4 of the radial 25
pocket in which the bolt [5a is reciprocable, as
later set forth. A bolt l5 of this type is opera
tive in the pocket l3, Fig. 1, and its inner end
interlocks in a bolt hole 811 in the rotative barrel.
When the barrel is to be turnably released the
bolt [5 is pulled outward so that its cross-pin I 5*)
may be turned out of register with the slots I4
and then rested on the rim of the~ pocket mouth,
as shown in Fig. l, with the inner end of the bolt
provide for the locking of the rod adjusting means
as to a main body element of the connector.
Also an object of the invention is to provide a
30 highly ef?cient means to secure the attachment
of the sucker rod to the connector for the loads
and stresses of use in pumping.
The invention consists in certain advancements
in this art as set forth in the ensuing disclosure
35
\ clear of the barrel 8.
35 and having, with the above, additional objects
The bore of the barrel 8 is provided with screw
and advantages as hereinafter developed, and
whose construction, combination and details of threads 8° and these are engaged by means pro
vided to rigidly, axially hold the usual polish rod
means, and the manner of operation will be made
3 to the lower end of which the pump rod string
manifest in the description of the herewith illus
(not shown) is connected. The rod holding 40
trative
embodiment;
it
being
understood
that
40
'means
includes an elongate sleeve [8 screwing into
modi?cations, variations and adaptations may be
resorted to within, the scope, principle and spirit
of the invention as it is more directly claimed
hereinbelow.
Figure l is a sectional elevation of the con
nector as applied to a polish rod of a pump. Fig
ure 2 is a sectional detail of a locking bolt of the
assembly. Figure 3 is plan of a bolt engaging
ring forming a spline of the connector parts.
Pump beams have divers types of links 2 for
50
attachment of the pump polish rod 3 by one form
or another of connecting units.
In the instant case the links 2 are engaged
45
under heavy hooks 5 projecting from opposite
55 ‘sides of a main connecting body element 6; the
the threads 80 of the barrel, its ends extending
beyond the barrel. The rod 3 slidably ?ts in the
bore of the sleeve l8 and means are provided to
securely clamp the rod 3 at the desired place in 45
the sleeve. The clamp device includes duplicate
chuck thimbles 20 each having a cylindrical bore
and being threaded at 23 on the ends of the
sleeve 18.
Slidably mounted in each thimble 2B is a pair
of cylindrical bushings 2| each conically bored
complementally to and receiving a chuck skein
24 having endwise converging portions fitting in
the respective bushings 2| and being longitudi
nally slotted inwardly from each end. When 55

the thimble 20 is screwed well onto the near end
of the sleeve N3 the ends of the pair of bushings
2 I, therein, will abut, one against the. near end of
the sleeve I 8 and the other against an internal
shoulder 20a in the thimble 20 with the result
that the slotted skein will be positively contracted,
ceive and hold the rod, a barrel in which the
sleeve is turnably threaded, a body in which the
barrel is turnably supported, and means inter
locking the sleeve and the barrel to the body
against rotation.

by the bushings 2|, onto and clamp the polish
which said means provides for releasing either
rod 3 so that it is carried by the screw sleeve
l8 and may be raised or lowered, or rotated there
the barrel or the sleeve for relative rotation as to
10 by at will.
The slots 22 of the skein extend past
each other to give desired ?exure.
Means are provided to positively rotatively in
terlock the rod carrying screw sleeve I8 to the
main body 6 to insure the feeding of the screw
15 sleeve up, or down, to raise or lower the rod 3
as desired.
This means includes the spring-set
latch bolt 158*, Fig. 2, mounted in the upper end
of the body 6, and whose inner end engages in one
or another of notches 26 provided in the rim of
20 a dog-ring 21 which is sunk in the top end of
the body 6 and retained between the upper end of
the barrel 8 and a flush plate 28 fastened in the
top of the body 6, as by screws 29. The dog
ring 21 surrounds the sleeve loosely and has an
25
internal dog or spline 21*‘, Fig. 3, slidably ?tting
in a longitudinal key-way [8a in the sleeve l8.
If it is desired to angularly adjust, or turn,
the polish rod 3 and its suspended pump parts in
a well it is only necessary to draw the bolt l5
30. from looking engagement with the barrel 8, in
bolt hole 8*’, and turn the bolt IE to carry its
cross-pin l5b away from its pocket slot M, Fig. 1,
so that the bolt may rest in open position. At
the same time the upper bolt l5a is similarly
35 drawn to release the dog-ring 2'! and turned to
open-rest position. It is now possible to turn
the lever II and by it the threaded barrel 8 and
the friction of the rod loaded sleeve l8 on the
threads 8° of the barrel will cause the sleeve 18,
with the sucker rod ‘string, to be turned with and
by the rotated barrel 8. Therefore, the rod and
its attached pump parts will have been angular
ly shifted on or as to bearing surfaces engaged
thereby.
Following this adjustment the bolts
45. l5—-—l5a are tripped to spring into normal look
ing relation with parts 8 and 21, respectively to
prevent undesired rotation of the rod clamping
sleeve as to the connector body 6.
To effect a longitudinal shift of the sleeve I8
50 without releasing the rod 3 in the chucks v2f] it is
only necessary to draw the bolt l5 and turn it to
open rest position of its pin l5b, thus unlocking
the barrel 8. The barrel is now rotated by the
hand lever II while the dog-ring 21 is still bolted
55 at 15a to the body 6 with the result that the
threads 8% react to raise or to lower sleeve 18, ac
cording to the direction of rotation.
When the desired axial shift of the rod 3 is
completed by action of the barrel on the screw
60 sleeve, the bolt I5a is again tripped to engage and
lock the dog-ring 27 to the body '6.
Angular adjustment or longitudinal shift of
the sleeve [8 and its clamped rod 3 may be ac
complished at will without it ‘being necessary to
65 stop the pump action or break down the con
nector in any way. The operation of the lever
I l is preferably timed on the down stroke of the
pump rod apparatus, that is, following the lifting
or load stroke since the friction of the threads
70 of the sleeve I8 is then much reduced below the
lifiting friction.
This application is a continuation in part of
my Patent 2,087,174 of July 13, 1937.
