Pierce's patent "relates particularly to that class of machines known as feather-edging or channeling machines for chamfering the edges of soles, (to be used in the manufacture of 'turns') in which the inner surface of each sole is generally made with a straight or nearly straight cut or gash at some distance from the edge of the sole, dipping down toward said edge, and thereby forming a flap and channel, at the bottom of which the stitches enter, and with a channeled or chamfered edge."
