A single encyclopedia entry defining the mangle, a machine for smoothing linen and cotton articles. It describes the common form, a weighted wooden chest of stones rolling back and forth on two cylinders over linen laid on a smooth bed, driven by a toothed wheel and pinion. It also mentions patent varieties, such as one in which linen is rolled on a cylinder pressed by hanging weights against a sliding curved bed, and gives the verb sense 'to calender'.
