Abstract
An adapter which can be used to enable a sucker rod to be rotated by tubing tongs includes a rod-mountable assembly comprising a sleeve in which the rod to be rotated is received, and a door which is mounted on the sleeve to rotate between an open position, wherein the rod can be received in the sleeve, and a closed position, wherein the rod-mountable assembly is held on the rod. Included in a preferred embodiment is a holding assembly adapted to be connected to the tubing tongs to hold a lower rod against rotation. A method of rotating a rod relative to a string of rods used in a well is also disclosed.

An adapter, comprising:
- a sleeve, including a first longitudinal slot defined therein;
- and
- a door, including a second longitudinal slot defined therein, said door movably disposed on said sleeve so that said door is movable relative to said sleeve between a first position, wherein said first and second longitudinal slots are aligned, and a second position, wherein said first and second slots are not aligned, said door further including:
- a collar in which said second longitudinal slot is defined, said collar concentrically mounted on the outside of said sleeve;
- a retaining member disposed on the inside of said sleeve;
- and
- means for connecting said retaining member to said collar so that in said first position of said door said retaining member is spaced circumferentially from said first longitudinal slot, and in said second position of said door said retaining member overlaps said first longitudinal slot.

An adapter for a rod used in a well, which adapter adapts the rod to be rotated by tubing tongs, said adapter comprising:
- adapter body means for internally receiving the rod through a passageway defined in said adapter body means and for externally receiving the tubing tongs, said adapter body means including:
- a longitudinal slot defined therein as the passageway;
- and
- a lateral slot defined therein so that said lateral slot intersects said longitudinal slot;
- and
- door means, mounted on said adapter body means and movable relative to said adapter body means between a first position and a second position, for opening the passageway into said adapter body means when said door means is in said first position and for closing the passageway into said adapter body means when said door means is in said second position, said door means including:
- a collar slidably and rotatably mounted on said adapter body means, said collar being open longitudinally through one section thereof;
- a retaining member disposed inside of said adapter body means;
- and
- a pin connected between said collar and said retaining member so that said retaining member is spaced inwardly from said collar, said pin disposed for riding within said longitudinal and lateral slots.

An adapter for a rod used in a well, which adapter adapts the rod to be rotated by tubing tongs, said adapter comprising:
- adapter body means for internally receiving the rod through a passageway defined in said adapter body means and for externally receiving the tubing tongs;
- door means, mounted on said adapter body means and movable relative to said adapter body means between a first position and a second position, for opening the passageway into said adapter body means when said door means is in said first position and for closing the passageway into said adapter body means when said door means is in said second position;
- and
- said adapter body means including:
- a sleeve, including a lower body portion and an upper body portion extending collinearly between two ends of said sleeve, said lower body portion having a greater outer diameter than said upper body portion so that said lower body portion is adapted to be engaged by the tubing tongs and so that said upper body portion is adapted to receive said door means, said sleeve further including the passageway thereof characterized as a slot defined therein between said two ends of said sleeve and adapted to pass an end of the rod therethrough;
- an upper stabilizer member disposed in said upper body portion at one end of said sleeve, said upper stabilizer member communicating with said slot;
- a central stabilizer member disposed in said sleeve in adjacent portions of said upper and lower body portions, said central stabilizer member spaced from said upper stabilizer member so that a partially annular space is defined therebetween within said sleeve, and said central stabilizer member communicating with said slot;
- and
- a lower stabilizer member disposed in said lower body portion at the other end of said sleeve, said lower stabilizer member communicating with said slot.

A method of rotating a rod relative to a string of one or more rods used in a well, said method comprising the steps of:
- supporting the string of rods so that the rod to be rotated is at the top of the string above the mouth of the well;
- mounting an adapter on the rod to be rotated, said step of mounting an adapter on the rod to be rotated including:
- moving an adapter body relative to the rod to be rotated so that the rod to be rotated passes through a slot in the adapter body and is received within the adapter body;
- and
- moving a member, mounted on the adapter body, relative to the adapter body until the member covers at least part of the slot to hold the rod within the adapter body;
- engaging the adapter with tubing tongs;
- and
- actuating the tubing tongs to rotate the adapter and the rod on which the adapter is mounted.

A method of rotating a rod relative to a string of one or more rods used in a well, said method comprising the steps of:
- supporting the string of rods so that the rod to be rotated is at the top of the string above the mouth of the well;
- mounting an adapter on the rod to be rotated, said step of mounting an adapter on the rod to be rotated including:
- moving an adapter body relative to the rod to be rotated so that the lower end of the rod passes through a longitudinal slot in the adapter body and nests in a stabilizer portion of the adapter body, which longitudinal slot is conformed to the shape of the lower end of the rod to be rotated;
- rotating a collar, mounted on the adapter body, relative to the adapter body until a retaining member connected to the collar is aligned with the longitudinal slot;
- and
- lowering the collar and retaining member relative to the adapter body to a position wherein the retaining member is adjacent the stabilizer portion of the adapter body;
- engaging the adapter with tubing tongs;
- and
- actuating the tubing tongs to rotate the adapter and the rod on which the adapter is mounted.
