  • the amount of displacement of the second rod 32 depends upon the torce ot puh and on the qualities and initial tension of the springs.
  • the maximum path of a rod upon pull or shock is given by the distance between the sleeves 103 kor 106 respectively from the ledge 1 or other suitable abutment. It is convenient that this path be considerably larger than half the distance that both drawrods 32 can move to or from each other.
  • the spring 48, the spring seats 100 and 119 are only on one rod 32, which is slidable with respect to the connecting sleeve 93, upon shock and draft.
