Mounting means for positive yarn feeding device and stop motion on a circular knitting machine

Claim 1

In a circular knitting machine having a support ring and having a positive yarn feeding device comprising a roller and a tape running over a first portion of said roller for positively feeding yarn between said roller and said tape, said feeding device having lever means movable to an out-of-action position in which the yarn is moved onto a second portion of the roller in which it is out of engagement with said tape, the improvement comprising, a. a bracket carrying said feeding device and adapted to be mounted onto said support ring, said bracket having a passage therethrough, b. switch means operatively connected to said lever means and closed when the latter is in said out-of-action position, c. cooperating means on said support ring and said bracket for electrically connecting said switch means to a power supply, said cooperating mEans comprising conducting surfaces on said ring and conducting means extending from said switch through said passage in said bracket, said conducting means electrically engaging at least one of said conducting surfaces upon mounting said bracket onto said support ring, d. a stop motion for monitoring yarn emanating from said roller, said stop motion including a switch biased into closed position upon breakage of the monitored yarn passing therethrough, e. support means carried by said bracket for supporting said stop motion, said support means including a conductive portion electrically connected to another of said conducting surfaces on said support ring by means of a conductor extending through said bracket passage, and f. cooperating means on said stop motion and said support means whereby said stop motion switch is electrically connected to said another conducting surface upon mounting of said stop motion onto said support means.
