UNITED STATES REX G. HAMAKER, OF HOUSTON, TEXAS.
CABLE BEARING FO'R WALKING BEAMS.
Application filed November 19, 1923. Serial No. 675,531.
To all whom it may concern:
Be it known that I, REX G. HAMAKER, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in a Cable Bearing for Walking Beams, of which the following is a specification.
This invention relates to'new and useful improvements in a cable bearing for walking beams.
One object of the invention is to provide an attachment of the character described specially designed for application to a walking beam and forming a cable bearing in which the pump operating cable works.
In pumping wells a walking beam is commonly employed, said beam being pivoted on a standard and connected, at one end, to the power through which it is reciprocated. At the other end the walking beam is connected to the pump rod by means of a rod clamp, secured to the rod, and a cable which is attached to said rod, and works in a cable bearing on the last named end of said walking beam. An object of this invention is to provide an improved type of cable bearing to be attached to said beam, and in which said cable works, without substantial injury to the cable.
Another object of the invention is to provide an attachment of the character described which may be readily fitted to the walking beam without cutting off or shaping the end of the walking beam to receive the same.
A further feature of the invention resides in the provision of a cable bearing through the operation of which a direct upward pull will be exerted, through the cable, on the pump polish rod, thus causing the uniform wear of said rod' as it reciprocates through the stuffing box.
A still further feature of the invention resides in the provision of a cable bearing which is of very simple construction, can be cheaply and easily manufactured, and easily applied to the walking beam, and which is very effective in use.
With the above and other objects in view, this invention has particular relation to'certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein:
Figure 1 shows a fragmentary side View of a walking beam showing the cable bearing attached thereto.
gigure 2 shows an end View of said beam; an
Figure 3 shows a fragmentary plan View thereof.
Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures the numeral 1 designates an upright standard on which the walking beam 2 is pivoted. The numeral 3 designates the pump tubing with the usual stufling box 4 at its upper end, through which the pump polish rod 5 works in pumping the well. The numeral 6 designates a polish rod clamp, of conventional construction, which is clamped on said polish rod.
One end of the walking beam is connected to the power through which said beam is oscillated up and down. This connection has not been shown, as it is in common use and well known. The other end of the walking beam is .connected to the olish rod 5 through connections present y to be described. Mounted on the last mentioned end of said beam there is a yoke 7. A cable 8 has its respective ends connected to the clamp 6 on opposite sides, said cable forming a loop, as 9, which works around said yoke 7, and the yoke has an arcuate groove 11) forming a bearing in which the cable works.
The yoke is secured to the beam by means of suitable bolts as 11, 11 and is also formed with an overturned transverse flange 12 which fits into a transverse groove 13, in the upper side of the walking beam, and serves as additional means for securing the yoke in place on said beam. For convenience in manufacture the yoke may be made in two sections, as shown in Figures 2 and 3.
Integral with the yoke on each side there are the depending arcuate cable guides 14, 14, which are grooved to form the cable bearings 15, 15. These guides fit closely against the sides of the walking beam, and are formed with ears 16, 16, which lie against said beam, and set screws 17, 17 are fitted through said ears and are screwed into said beam to strengthen said guides, and secure the yoke more firmly in position.
The guides 14 depend some distance below the walking beam, and braces 18, 18, are anchored to said depending ends, and to the walking beam, respectively, and strengthen said depending ends.
It is to be noted that the guides 14: converge downwardly, to coincide with the downwardly converging ends of the cable 8.
The cable bearings 15 are substantially arcuate, and form arcs of circles having their centers at the center of the pivotal mounting of the walking beam. The polish rodis thus substantially tangential to these cable bearings, at all times during the operation of the walking beam, and as a consequence a direct upward pull is exerted on said rod thus preventing the bending or uneven wearing of the same.
What I cliam is:
1. An attachment for walking beams including a yoke having a cable bearing, and a pair of cable guides depending from the yoke, on opposite sides of the beam.
2. An attachment for walking beams including a yoke having a cable bearing, and a pair of grooved cable guides depending from the yoke, on opposite sides of the beam.
