Definitions

  • the mechanism also includes a second member which normally occupies an operative position in which it projects under the trolley track to restrain forward movement of a trolley at the holding station.
  • a pneumatic piston-andcylinder device On receipt of a signal from the next holding station along the track that the preceding trolley is clear of this next station, a pneumatic piston-andcylinder device moves the stop arm into its inoperative position to cause a pusher to engage the driving dog of the detained trolley, and another such device allows the second member to move forwardly gradually into its inoperative position to cause a smooth forward movement of the trolley under the action of the pusher.
  • FIG. 3 is a plan view of the mechanism shown in FIG.
  • a conveyor according to claim 1, wherein said means comprises a fluid pressure circuit containing a fluid-pressure actuated .piston-and-cylinder device which is connected to said second member and the fluid pressure in which serves to counteract partially the driving force of a pusher on the driving dog of a trolley restrained by said second member.
  • said circuit also comprises a double-acting pneumatic changeover valye which is connected to said device, wherein said device is double-acting and is controlled by said change-over valve, and wherein said change-over valve is controlled by firstand second pneumatic valves.
