It differs from stops No. 1 and No. 2 in being capable which tiiriis switch' K, to close groove il', and open groove 1l, which shifts the position of the parts,'a'nd throws hooknin working position. v.

After pin/n leaves the bottom of track 2, it strikes :ory, iio matter which way the feeding mechanism is working, or. en which of, the rows. The .crossing over?1 of the yarn-'carrier from one side -to the other is accomplished with certainty, and always at` the rglittiine, by the peculiar construction ot' the caniopeniug 1f, stud p, and switch K.

By observing the operation of the machine in heel or dat work, it will be seen that the latch-lever P must be operated from-its front end to reverse the wormer,

By reversing the wormerjust/before it enters thc feed-rack', as is done hy'stop No. 3, this point is gained', as switch tis changed` in time to give the yarn-carrier'the proper movement to insure this result. j

The stops Nos. 1, 2, and 4de until it 'has passed neariythrough the feed-rack, and,l with the wormeiswitcli t, .is reversed,' whereby`.the yarn-carrier is tnrnedvback, and passesoiit throng-hI the saine spacev between the hooks a aby whichit enters, and no loop is left on the last hook, a, traversed by the looper-hook.
