Appletons' cyclopaedia of applied mechanics: a dictionary of mechanical engineering and the mechanical arts . ine. A machine adapted to this secondsizing has been devised by Mr. J.Yero of Dewsbury, England, andimproved by Kirk, Shelmerdine, andFroygate, of Stockport, England.The improved apparatus has fourrollers driven all in the same direc-tion by gearing. The lower pair ofrollers is journaled in the station-ary frame, while the upper pair isjournaled in a swinging frame, whichcan be lifted up whenever the hat-roll is to be inserted or removed.The working surface of the rollersis formed of elliptical rings, madeof India-rubber, and placed so as tooverlap each other. Generally, tworolls of hats are kept in operation, one roll being acted upon while the positions of the hats in the other are being changed. Fig. 2299 represents a machine of this class. Two beaters act upon the ends of the hat-roll.Four cubical pressers are provided, so arranged that the hat-roll is pressed at each quarter revolutionof the pressers. These are journaled upon two swinging frames, which are so connected by links to.
