A short dictionary entry describing the hat-finishing lathe, introduced by John T. Waring, in which a hat on a chuck is rotated while sanded or retouched. It explains the treadle-and-belt drive of the basic lathe in Fig. 1324 and the Eickemeyer oval hat lathe in Fig. 1325, which was developed for finishing oval hat blocks. It covers hat-making machinery rather than weaving.
