英文释义

名词 n.
  1. A hand-operated jumper. Scotland
    — It may be noted here that all the holes were bored with an ordinary boring ratchet, and although the hole is larger than the one prepared for powder, yet it was not considered that any extra labour was taken in the boring owing to the boring ratchet being used instead of the ordinary jumper or kirner.
