Abstract
A mounting system for a fill-up and circulating tool on the rig hoisting system is disclosed. In the preferred embodiment, the tool is supported on one of the bails and it driven to rotate around the longitudinal axis of one of the bails. A combined vertical and rotational movement is imparted by the mounting system to allow the fill-up and circulating tool to be raised and swung out from between the bails to allow normal drilling or tripping. In the other position it can be swung over the tubular and lowered for sealing contact to allow fluids to pass in both directions to or from a pumping and storage system on the rig.

An apparatus, mounted to a hoisting system in a rig having a longitudinal axis, defined by a pair of bails supporting an elevator, for selective positioning of a fill-up and circulating tool in a first position for contact with a tubular in the elevator and in a second out of the way position to allow drilling or tripping pipe, comprising:
- a frame supported on the hoisting system;
- a mechanism mounted to said frame and supporting the fill-up and circulating tool;
- said mechanism capable of selectively translating the fill-up and circulating tool to move the fill-up and circulating tool into or out of alignment with a tubular in the elevator or to raise or lower the fill-up and circulating tool for selective contact with the tubular.
A handling apparatus for a fill-up and circulating tool, comprising:
- a pair of bails, each having a longitudinal axis, and supporting an elevator;
- a frame mounted to one of said bails;
- a mechanism connecting the fill-up and circulating tool to said frame;
- said mechanism capable of selectively translating the fill-up and circulating tool to move the fill-up and circulating tool into or out of alignment with a tubular in the elevator as well as to raise or lower the fill-up and circulating tool for selective contact with the tubular.
