The follower plate is then brought down on to the FLANGING-MACHINES. 365 head by means of the screw and hand-wheel at the top. This follower is so made as to bearhardest at the outside, and comes down with an outward pressing motion, which keeps the. Clarks flanering-machiue. head straight and flat on the former while being turned. The machine is then set in motion,and the straight or break-down roll brought against the edge by means of the large screwin the bed. This roll is so mounted as to enable it to be pre-sented at any desired angle, and can then be gradually brought toa vertical position by means ofthe hand-screw on the carriage,being kept up to the head at thesame time by means of the largehand-wheel and screw. The fin-ishing-roll, which is made of theshape it is desired the head tobe, is at the opposite side of themachine, and is brought up tothe head in the same manner,though it is fixed in a verticalposition. As the first roll isbringing the edge of the headdown to the former, the finish-ing-roll is brought up and com-pletes the head. Hooks areplaced in the follower, whichtake hold of the lower edge ofthe head, so that it is drawn offby means of the hand-wheel andscrew on the top of the Boiler-Head Flang
