Claim 10

Dependent Claim 47 words

The combination of claim 5 wherein said rotary actuator includes a spur gear attached to the arm, to rotate therewith, a rack meshed with said gear, and a linear actuator connected with the rack to linearly displace the rack, and thereby rotate the gear, arm and head.

Claim 11

Dependent Claim 36 words

The combination of claim 1 including means to temporarily block pivoting of the arm to said first position until the wire section is located in predetermined position to be gripped by said clamp on the head.

Claim 12

Dependent Claim 59 words

The combination of claim 10 including a locating clamp associated with wire strand severing and insulation stripping apparatus, to located a succession of wire section in said predetermined position, and an actuator to operate said locating clamp to successively clamp said sections in said predetermined position and to release same when the clamp on the head grips each section.

Claim 13

Dependent Claim 61 words

The combination of claim 10 wherein said temporary blocking means includes a part swingable with said arm, a stop movable between a primary position in which it is engaged by said part, and a secondary position in which the stop allows completed swinging of the arm to said first position, and yieldable means to urge the stop into said primary position.

Claim 14

Dependent Claim 35 words

The combination of claim 12 including means to control said yieldable means to allow completed swinging of the arm to first position after clamping of the wire section in said predetermined position to be gripped.

Claim 15

Dependent Claim 40 words

The combination of claim 2 including a stop shoulder on the head engaged with a stop shoulder associated with said terminating means, to limit extension of the arm in said second position when the wire section is positioned for termination.

Claim 16

Dependent Claim 23 words

The combination of claim 14 including said terminating means, which is non-integral with wire section supply means relative to which said arm pivots.

Claim 17

Dependent Claim 15 words

The combination of claim 15 wherein said terminating means includes wire section peening hammer structure.

Claim 18

Dependent Claim 49 words

The combination of claim 15 wherein said terminating means includes hammer and anvil structure characterized in that the hammer bodily deflects the wire section toward the anvil, said telescopic interfit of the guide and locating guide providing sufficient clearance to permit corresponding bodily deflection of the head and clamp.

Claim 19

Dependent Claim 22 words
