Abstract
An ejection mechanism, which in one embodiment selectively ejects pipe joints to either side of a pipe arm and method for manufacturing the same. A pipe arm contains a plurality of pipe receptacles for receiving pipe joints. Pipe ejection arms are operatively connected to an ejection control mechanism. In one embodiment, at least one torsional member and/or at least one hydraulic actuator allow an operator to selectively eject pipe joints to either lateral side of the pipe arm as needed during drilling and production operations.
