ADJUSTMENTS.

In setting the steel harness stop-motion the first thing to do is to either throw off the belt, or remove the key which holds the end of the shipper-lever in the shipper-handle (in our later looms), and place the shipper handle in the notch in the shipper-lock; this will bring the stop-motion into the same position as when the loom is running. Then turn the loom until the feeler-bars are in their extreme forward position under the girt. The knock-off link should be against its bearing in the hub of the cam, and the cam-follower should bear against the cam in its lowest place. The small casting on the same stud as the cam-follower, called the knock-off, should be so set that it will just clear the projections on the hub of the cam as the cam revolves on the cam-shaft.

The cam on this stop-motion is very similar to that used with the cotton hai^ness stop-motion. The position of the oscillator-cam is governed entirely by the harness-cams and should work in conjunction with them. When this cam is meshed with the harness-cams, which it does when the harness-cams are on the cam shaft, it must, of course, move with them; but when the harness-cams are on the auxiliary shaft, care must be used to run the oscillator-cam in the right position. In this case, when the harnesses are level or passing each other, the oscillator cam should be so set that the long axis of the cam is horizontally level, or in other words, so that the faces of the cam point directly to the front and back of the loom on a horizontal line with the floor.

The cam-follower is held in position by a spring on the stud to which it is fastened; if it does not follow the cam as quickly as it should, tighten this spring. Care should be taken, however, not to have too much tension on this spring, but just enough to make the cam-follower work properly; otherwise the
