For a rove of 70/75 lbs. perspindle, the twist pinion is 35, with 2| drawing roller; rack pinion,15 ; and traverse pinion, 28 teeth. Note.—Roving Rack Pinion.—A mark on the side of one ofthe teeth in the pinion is put there for a guide. When you put ona rack pinion, the top catch should be into the marked tooth, afterthe rack is wound up.
