Definitions

  • Fig. 2 is a side view partially in section of one embodiment of the invention.
  • the arrangement is such that a buff force applied to either the rod 30 or the rod 3I results in full compression of both springs when rigid connection is established between the draft gear and the vehicle.
  • the rods 30 and 3l are yieldingly connected together in the same manner as in Fig. l by a rod spring 5T.
  • the rod spring 51 bears against spring followers 58 and 59 mounted for longitudinal movement on the ends of the rods 38 and 3l.
  • the rod spring 51 presses the followers 58 and 59 against abutments BIJ and 6I on the rods 38 and 3
  • the rod spring 32 is mounted within the frame spring 33 and bears against followers 34 and 35 toforcel them toward the'abutments 33 and 31 on the rods 42 and 43.
  • the rod 43 is provided with an abutment 54 engaged by a plate 46.
  • a tube 38 surrounds the rod spring and has a flange 39 at one end engaging the outer face of the follower 34 and a flange 4B at the other end engaging the outer face of a collar extending from the abutment 31.
  • a draft gear for vehicles comprising a frame extending longitudinally of the vehicle, a rod extending longitudinally of the frame, abutments on saidrod, followers engageable with said abutments, a spring interposed between said followers, stops on said frame, one of said stopsl being directly engageable by one of said followers, a twopart spacer interposed between the remaining follower and stop, arcuate levers supported by one spacer part with one of said ends engaging the other spacer part and the remaining ends in position to be engaged by one of said abutments to effect movement of the second spacer part away from the first spacer part, and means for limiting movement of the followers toward each other.
  • a draft gear for vehicles comprising a frame extending longitudinally of the vehicle, a rod extending longitudinally of the vehicle, two stops on said frame, members engageable with said stops, a spring tending to maintain said members in engagement with said stops, one of said members being expansible, means for moving the other member toward the expansible member upon movement of said rod in one direction, expanding means for said expansible member, and means on said rod engageable with said expanding means to actuate the same.
