around the terminal whicli is inserted in hole a of the rotating member. 

 The connecting wire is inserted at b and is anchored by a slight force 

 against the outer stationary member of the tool. As the inner member 

 rotates, the connecting wire is stretched and formed around the terminal 

 until all of the wire length is used. It should be noted particularly that 

 all of the wire is used, making it unnecessary to clip a wire end as in 

 other wiring methods. This is an important detail in avoiding wire clip- 

 pings which sometimes cause unwanted cross connections in wired equip- 

 ment units. The tool tip described can be operated by a hand trigger 

 or by motor. Fig. 36 shows a hand powered tool primarily for installation 

 and repair service. Fig. 37 shows a production type tool driven by air 

 l)ressure developed by the Western Electric Company at the Hawthorne 

 Works. Fig. 38 shows a tool driven by an electric motor used by the 

 Kearn}' Works of the Western Electric Company. Fig. 39 shows a 

 wrapped connection on a wire spi'ing relay prior to soldering.
