  • Patent number: 10273762
    Abstract: An on-off tool for latching a sucker rod to a plunger rod has a housing, a pawl, guide pines, and a key. One end of the housing is connected to the sucker rod, and an interior of the housing defines a key slot terminating at a seat inside the interior. The pawl is disposed in the interior of the housing and is biased longitudinally preferably by disc springs. Bearings in the form of elongate pins are engaged between the pawl and the housing and dispose longitudinally in slots to guiding longitudinal movement of the pawl in the interior and preventing rotation of the pawl. The key has a head at its distal end that is passable through the key slot, interlockable with the pawl, and seatable on the seat. The key's head preferably defines a waist thereabout to provide the head with greater load bearing surface to engage the housing's seat.

  • Patent number: 4413689
    Abstract: According to a depicted embodiment thereof, the novel earth bit comprises a shank having a threaded end and a bit head centrally bored and threaded to receive a shank. A stack of apertured discs, however, is interposed between the threaded bore or cavity in the bit head and the threaded end of the shank. The discs intimately engage, and bridge between, the shank and bit head threads, and communicate torque therebetween. The bit head cavity has a bearing surface or land upon which the discs are supported, and the shank has an annular shoulder which bears upon the stack and, thus, compressive forces are communicated from the shank to the bit head. The bit head, of the invention, then, comprises the aforesaid bit head, having the stack of discs secured therein by a retainer, for use, in a plural-part earth bit having a threaded shank.
