Definitions

  • FIG. 1 is an elevation of one part of the device.
  • the broaching cutter 8 is carried by the impact pin 7 which has two parts, i.e., an upper part 24 bearing in the adaptor 19 and a lower part 25 bearing in the bearing sleeve 22.
  • the broaching cutter 8 is carried on the part 24 of the impact pin 7 and rests against a step 26 between the two parts 24 and 25.
  • the part 25 of the impact pin 7 projects from the bearing sleeve 22.
  • a stop in the form of a washer 27 and a nut 28 is carried on the end 29 of the impact pin 7 where it projects from the adaptor 19.
  • the control rod 1 then continues to fall freely until the downwardly projecting impact pin 7 of the broach strikes an impact stool 32 situated at the foot of the control rod channel.
  • the im pact pin 7 is arrested by the impact stool 32 and due to the impact the broaching cutter 8 is forced along the liner 9.
