roller 212 then swings arcuately around arbor 222 as seen in fig1 bending leg 324 around the mandrel to form a hook 328 during the movement of bending lever 200 tension spring 214 keeps cam follower 208 in contact with cam 196 and roller 210 travels along channel iron 211 to maintain the desired orientation of the bending lever the degree of overbend of hook 328 is governed by the adjustment of locking nut 192 on piston rod 190 it should be noted that the axis of cam follower 208 does not move below the projected axis of piston rod 190 on the return stroke of piston rod 190 pusher cam 196 comes into contact with arm 240 of bell crank 234 causing the bell crank to pivot about pin 236 against the action of spring 248 and moving pusher plate 230 outwardly from head 220 to move hook 328 laterally off mandrel 222 as seen in fig1 of the drawings each hooking mechanism 16 is then retracted on spindle 86 by hydraulic unit 304 in the final operation step carrier 12 advances coil spring blank 320 to station iv between opposed wire cutters 18 when the operator again depresses treadle 70 to load the carrier for the wire cutting operation each wire cutter 18 is adjustable in three mutually perpendicular directions and may be exactly located by 1 adjusting clamp 254 on slide bar 256 as indicated by arrow 330 in fig1.
