The wire having been headed by a machine , the forged blanks are carried to the turning and nicking machine , and are placed in a hopper above the machine , from which they are taken one by one by a mechani- cal arrangement which places them in the machine , where the heads are first turned, then nicked, and lastly, re-turned to remove the burr left by the nicking saw.
Mr. Chamberlain, writing of this invention, says : — " The process may be shortly described.  The wire having been headed by a machine , the forged blanks are carried to the turning and nicking machine , and are placed in a hopper above the machine , from which they are taken one by one by a mechani- cal arrangement which places them in the machine , where the heads are first turned, then nicked, and lastly, re-turned to remove the burr left by the nicking saw.  The blank, thus nicked and turned, is then delivered by the machine into a bucket placed to receive it.
