  • the lower portion 42 of the outer surface of the cylindrical portion 39 is threaded. so as to threadedly receive a nut 47. as seen in FIGS. 5 and 6.
  • the top edge ofthe nut 47 engages the ring 46. so that the position of the ring 46 and the end member 43. relative to the bent bar 37 can be adjusted by turning the nut 47 engaging the threaded portion 42 of the bent bar 37.
  • the lower end of the end member 43 is pivotally connected to the chain 48 by a chain pin 49 through a U- shaped connector 44. as shown in FIGS. 4 to 6.
  • the U shaped connector 44 has arcuate edge surfaces 441:.
  • the pipe member a and b are aligned by engaging a part of the threaded portions thereof. as shown in FIG. I.
  • the pipe-holding chain 18 of the first holding means A is released from the hook 4. and the vice-pieces II are placed respectively in a proper position on the peripheral surface of the first pipe member a.
  • the chain [8 is wound around the pipe member a. and it is looped by connecting a suitable part of the chain 18 to the hook 4 of the body 1 by a chain pin 9.

  • the not 47 is turned in such a manner that the end member 43 of the chain 48 is moved away from the pipe member b.
  • the chain 48 is tightened against the peripheral surface of the second pipe member b. while causing the serration 32 of the swingable bar 30 and the arcuate surface 44a of the connector 44 to engage the peripheral surface of the second pipe member b.
  • the swingable bar 30 is turned about the longitudinal central axis of the aligned pipe members a and I). while the hydraulic cylinder 27 itself is slightly swayed about the shaft 24.
  • the first holding means A is held stationary. for instance by connecting the bracket or the body 1 to a stationary member (not shown).
  • the turning of the swingable bar 30 results in a rotation of the second pipe member b in a direction. as shown by arrow 55 in FIGS. 3 and 4.
  • the coil spring 50 provides a kind of buffering action in the pipe turning operation by the swingable bar 30. and the serration 32 assists in transmitting the turning movement of the bar 30 to the pipe member b.

  • the piston rod 28 may be retracted to to the cylinder 27 by suitable hydraulic action, the operating engagement of the serration 32 with the peripheral surface of the second pipe member b being released.
  • the reverse movement ofthe piston rod 38 i.e.. the movement toward the hydraulic cylinder 37. will cause the bar 30 to swing back. but the chain 48 slides along the peripheral surface of the pipe member b without turning the pipe member b. because the friction between the two pipe members a and b at the threaded portions thereof is large enough to allow the sliding reverse movement of the serration 32 and the chain 48 on the peripheral surface of the second pipe member b.
  • the second pipe member b will axially move toward the first pipe member a in response to the aforesaid rotation of the former. due to the threaded engagement therebetween. Such movement of the two pipe members in the axial direction thereof will be absorbed during the sliding reverse movement of the chain 48 of the second pipe-holding means B and by sliding of the hydraulic cylinder 27 on the shaft 24.
  • the power wrench of the present invention can be used to cause the second pipe member I: to rotate in a direction opposite the arrow 55, eg, for releasing the threaded connection of the second pipe member h to the first pipe member a.
  • the first holding means A may be mounted and tightened on the second pipe member 11 and kept stationary by a suitable means (not shown). and the second holding means B may be operatively mounted on the first pipe member a.
