- Still another object of the present invention is to provide a spinner unit for a swivel spindle whereby the swivel spindle may be rotated simultaneously and independently of continued rotation of the well string in a well bore whereby a tubular member supported by the swivel spindle may be either threadedly connected or disconnected into the rotating well string.
- Still another object of the present invention is to provide a power spinner for the spindle of a swivel which is constructed and arranged to selectively engage and rotate the spindle in either a clockwise or a counterclockwise direction as desired.
- Still a further object of the present invention is to provide a power spinner for a swivel spindle wherein a source of power is connected to operate the spinner, the power supply also functioning as a means to lubricate certain components of the spinner of the present invention.
- Yet a further object of the present invention is to provide a spinner unit for rotating the spindle of a swivel which is normally disengaged from the spindle but which automatically engages with the spindle when power is supplied to the spinner unit.
- Yet a further object of the present invention is to provide a spinner unit for rotating the spindle of a swivel which is normally disengaged from the spindle but which automah.
- Still a further object of the present invention is to provide a spinner unit for the spindle of a swivel which may be used for performing various operations on a well location.
- Still a further object of the present invention is to provide a spinner unit for the spindle of a swivel which may be used for performing various operations on a well location and which may be easily and quickly positioned on the spindle and easily removed for repair or replacement when necessary.
