Abstract
A pipe positioner for holding an end of a drill pipe in an earth drilling machine which is especially suited for use during blast hole drilling. The pipe positioner is connected to the mast of the earth drilling machine in a tubular guide frame arrangement which will allow movement of the pipe positioner inwardly and outwardly with respect to the mast. The pipe positioner includes jaws provided by slide bar members positioned in the guide frame of the pipe positioner. A double acting hydraulic cylinder connected to a pivoted linkage moves the slide bars to engage or disengage the pipe. In a preferred manner, the frame member for the jaws is provided by telescoping tubular members and the mast is of the tilting type for angle drilling.
