A dictionary entry for "Picker" from Knight's American Mechanical Dictionary, with two illustrations of cotton-picking and cleaning machines (Figs. 3694 and 3695). It describes how these machines open bale cotton and remove dirt and burs, then forms a lap. It also lists other senses of the word, including a cloth-burling implement, a priming-wire, a founding tool, and the picker of a loom's picker-staff that drives the shuttle through the shed.
