Electric conductor wrapping tool

In a conductor wrapping tool of the type having a case housing drive means selectively engageable with a drive shaft connected to a rotary bit, and having index means for stopping the bit in a predetermined position after disengagement of the drive means and drive shaft, the improvement which comprises:

• circular tongues of radially stepped configurations formed in the case,
• corresponding internal members each having a corresponding groove formed therein for receiving said tongues in rotation-opposing engagement therein;
• and
• at least one separate elastomeric member means frictionally engaged between the drive means and drive shaft for applying controlled torque such that the drive means is gradually arrested after driving disengagement from the drive shaft and stoppage of the bit.

A conductor wrapping tool, comprising:

• a case;
• a drive shaft positioned inside said case;
• drive means located at one end of said drive shaft, said drive means being supported by said case;
• a bit connected to the opposite end of said drive shaft;
• index means secured to said case for rotatably positioning said drive shaft;
• clutch means mounted on said drive shaft for rotation therewith and movement therealong between a first position in driving engagement with the drive means and a second position in stopping engagement with the index means;
• means mounted in said case for controlling actuation of the drive means and clutch means;
• and
• separate controlled torque means frictionally engaged between said drive means and drive shaft after indexing position has been achieved for gradually arresting said drive means after disengagement from the clutch means and stoppage of said drive shaft.

A conductor wrapping tool, which comprises:

• a case;
• a drive shaft positioned inside said case;
• drive means located at one end of said drive shaft;
• means including circular, radially stepped tongue and groove structure formed in said drive means and adjacent case for constraining said drive means against rotation relative to said case;
• a bit connected to the opposite end of said drive shaft;
• index means positioning said drive shaft for rotation;
• means including circular, radially stepped tongue and groove structure formed in said index means and adjacent case for constraining said index means against rotation relative to said case;
• clutch means mounted for rotation with said drive shaft and movement therealong between a first position in driving engagement with said drive means and a second position in stopping engagement with said index means;
• means mounted in said case for controlling actuation of said drive means and clutch means;
• and
• separate controlled torque means frictionally engaged between said drive means and drive shaft after indexing position has been achieved for gradually arresting said drive means after disengagement from the clutch means and stoppage of said drive shaft.
