slidingly receives an elongated connector rod 478 a connector stop plate 480 is secured to flat surface 444 over port 438 rod 478 is also slidingly mounted in connector plate 480 rod 478 has a connector bar 482 fixed to its lower end and a connector bar 484 connected to its upper end to keep both ends of the rod outside of the respective connector stop plates connector assembly 474 includes a connector stop plate 486 welded to flat surface 450 of connector plate 436 over port 438 an elongated connector rod 488 is slidably mounted in connector stop plate 486 connector rod 488 has a threaded end 490 threadedly mounted in top plate 336 the lower end of connector rod 488 has a connector bar 492 fixed thereon guide post 342 has a guide post stop 494 mounted on its upper end and held in position by a conventional screw 496 in operation when ram 306 is in its lowermost position cylinder 314 is in the attitude shown in fig1 that is all of the actuators are compressed as the ram 306 rises it pushes up on rods 318 and 320 to push up the cross beam 316 and thus pull pipe 338 upward which carries with it top plate 336 as the top plate 336 moves upward it extends actuator 334 until the actuator is fully extended the connector assemblies 474 then are connected to guide follower 332 to pull the guide follower upward and thus pull upward actuator 330 when actuator 330 is fully extended connector assemblies 472 pull.
