Abstract
A tubing connector wrench having a rotating hub held by two independent pawls. An open end of the hub and casing of the wrench allows it to engage over a piece of tubing and thereafter be engaged on a tubing connector. The wrench may be employed to turn tubing connectors without removing it for repositioning. The two pawls insure that the hub remains engaged for one way turning of the connector.
Claims9
A kit for rotation of tubing connectors rotationally engaged upon tubing, comprising:
- an open end wrench casing;
- a swivel handle, said swivel handle having a forked end having a recess formed between opposing sidewalls of two forks;
- and
- a wrench extension member;
- said wrench casing comprises a wrench head having a first end opposite a second end and having a first side surface and second side surface both respectively extending between said first end and said second end of said wrench head;
- a hub, said hub having an exterior circumference, and having an interior aperture defined by an interior aperture edge surface of said hub;
- a gap communicating between said interior aperture and said exterior circumference;
- said hub rotationally engaged within a head aperture formed at a first end of said wrench head, said head aperture having an opening communicating between said head aperture and an exterior surface of said wrench head;
- said opening having an opening diameter sized at least as large as a diameter of said gap;
- means for a ratcheted engagement of said hub within said head aperture whereby said hub turns freely in only one rotational direction;
- said interior aperture edge surface forming an aperture shape which is complimentary to an exterior shape of an exterior surface of said tubing connectors;
- said wrench head having a projection extending away from said second end of said wrench head opposite said gap at said first end of said wrench head, said projection having opposing sidewalls communicating between a first side of said projection running parallel with said first side surface of said wrench head and a second side of said projection running parallel with said second side surface of said wrench head;
- said sidewalls of said projection removably engageable in a swiveling engagement between said two forks of said swivel handle;
- a wrench extension aperture communicating between said first side surface and second side surface of said wrench head, said wrench extension aperture formed in said wrench head between said second end and said head aperture, said wrench extension aperture configured to removably engage upon a distal end of said wrench extension member which is rotatable by a handle engageable at a first end of said extension member;
- said interior aperture positionable to a removable engagement of said aperture edge surface with said exterior surface of said tubing connector;
- said wrench head with said interior aperture in said removable engagement being rotatable by said swivel handle engaged with said projection at said second end thereof;
- and
- said wrench head with said interior aperture in said removable engagement being rotatable by rotation of said extension member engaged with said wrench extension aperture.
