This invention relates to rod-line weights. In handling strings of sucker rods in oil wells it is customary to raise and lower the rods in e derrick by means of s hoisting line connected at the upper end of a. string of rods and running over a. pulley at the top of the derrick and thence down to a power operated reel. Sucker rod strings are comparetively light in weight and the hooks and other tackle used with the hoisting line for connection with sucker rods are relatively smell. It has been found that hooks'of small weight retard the operation of handling the sucker rods because they will not descend at e sufficiently high speed or perhaps not at all. In order to speed up the downward trevel of the hoisting hooks rod-line weights have been introduced. These weights used in connection with the hooks should be so constructed that their connect-ions will be free to allow the weights to swivel or rotate because the rods have-e tendency to spin or rotate when hoisting. These weights may weih as much as five hundred pounds. Accoringly. when they are rotating due to the.
twisting action cit" the hoisting cable they have s lerge momentum which can not be destroyed by the operetors without liability oil their being injured. Furtheorethe rotating or spinning weights may by engagernent with the operators or structures essometed with the derrick cause more or less p Referring. rst to Figs. 1 end 2, 1 is inury. Furthermore it is necessary that wen-each stand of rods is hoisted in the derrick their connecting joints be unscrewed which would be prevented or interfered with in case the heavy weights were'spinning. Referring to the accompanying drawing, Fig. 1 is e central vertical section of one form of e weight with the hooks end their shenks shown in side elevation.
Fig.2 is s topplan view of Fig.1.
Fig. 3 is a view similar in character to Fig. l but showin e modification. h
t e body of the weight which is made of metal and 2 are hooks connected to the upper and lower ends'of the weight.
As the structures at the opposite ends of the weight are identical the same reference nunot reach to the bottom thereof. The hooks have shanks or stems 6 having their longitudinal axes in the control longitudinal axis of the weight and extendin into the recesses 3 where they are provide with the nuts 8 between which and the inner ends of the plugs are positioned roller bearings 9. The plugs are prevented from rotation by means of the screws 10 located partly in the plugs and partly in the well 0 the weight.
The weight is provided with oil passages 11 leading from the periphery of the weight to the recesses 3. The outer ends of the passas 11 are provided with Alemite or other suitable fittings, their outer ends not extending out to the periphery of the weight.
The opening in each hook 2 is closable by the link or closure 14 secured to the hook et the opposite ends of the openin by the- bolts 15 and 16. In order to open seek the bolt 16 may be removed and the link 1% swung outwardly as shown in dotted lines in Fig. 1. Referring now to Fig. 3, the weight is composed of two members 1a andrlb united on a transverse plane preferably-midway be tween the ends of the weight. The assembled members 1a and 1b resemble the integral weight 1 shown in Fig. 1'. The recesses 312 have their inner ends open while the shanks of the hooks-2 are mounted in the bod of the members 1a and 1b. The said mem rs are held together by the bolts 19 extending longitudinally through the members und heving their heads 20 in recesses 21 in themember lb and the securing nuts 22 in the recesws 23 in the member la. The heads 20 and'the nuts 22 us well as the upper ends of the bolts 19 do not reach the surface of the weight.
In both fee of my invention the ends or" lie the weight are inclined outwardly toward l the center portion of the weight. ese ends are substantially dome-shaped or frusto-conicel in order that the weights may not onage an object and be stopped thereb or do I damage thereto. The ends of the weight will elther move laterally when they engage an object or the object will itself move later- 5 ally with no tendency of the weight being blocked by the object or carrying it along therewith.-
In Fig. 3 thehook 20 has been modified from that shown in Fig. 1.' The hook in Fi 3 is carried by the transverse pivot 18.
claim: 1. A weight having oppositely disposed o enings at its ends, removable bushings in t e openings, hooks having axially-rotatable 5 shanks extending through the bushings and into the openings beyond the bushings, enlar ements on the inner ends of the shanks, an antifriction bearings between each bushing and the adjacent enlargement.
2. A weight divided transversel and having recesses at their meeting ends, ooks having axially-rotatable shanks in'axially-aline'd openings in the members of the weight and extending into the recesses, means in the re- 25 cesses for retaining the shanks in the openings, and means for securing the members of the weight together.
3. For hoistin hooks, a weight having bushings screw into its ends, swiveled members rotatable in the bushings and supported by the inner ends of the same, a screw engageable by each bushing and the adjacent portion of the weight to prevent the bushings from rotation, oisting hooks carried by the swiveled members, and openin' in the weight to transmit lubricant to the frictionally engaged surfaces between the bushings and the swiveled members.
In testimony whereof, I hereunto aflix my signature.
