DEFINITION

Classification: 112/80.44

Means to disconnect needle and drive:

(under subclass 80.4) Device for making and braking a motive coupling between (1) the strand inserting means and (2) an element which imparts reciprocation to the strand inserting means to cause the strand inserting means to penetrate the material.

(1) Note. This subclass includes devices (1) means to disconnect a needle bar and a needle to prevent the needle from reciprocating or (2) means to disconnect a needle bar and the bar's drive means.

(2) Note. A device having merely a switch which turns on a

tufting machine's drive motor is not included in this subclass.
