3 save/wives now be readily understood is a pin on which the stop roller 46 is journaled A crank arm 47 which is keyed to the other end of the shaft as carries a pivot 48"to which isconn'ected the forward end of a rod 49 which carries-an. adjustable collar 50 to which is pivotally connected oncn ar1n5l ofga lever WlllCll 1s ournaled on av the beginning of the operation, sucker 10 having been lowered to the top cardboard sheet of the pile P. Closure 25 being in closed position, the top sheet seals the pneumatic system in such a way as to cause an immediate evacuation of t'he'cylinder which is accompanied by an upward movement of the piston therein and sucker 10 connected thereto. The parts now assume the positions shown in Fig. 3, in which the roller" stop 46 has moved rearwardly, while the sucker 10 has been elevated, thus serving to admit a blast of air beneath the rear corner and edge of the cardboard sheet. Cam 33 has by this time reached a position which permits the clamping foot 3-1 to'drop to the'pile in therear of the top sheet, thus assuming thejposition shown in Fig. 4:.
This movement permitsthe pin 4% carried by "the forward end of lever 29, to drop upon the cam rod 43 which projects rearwardly from the socket ll, thus causing the 40 stop roller 46 to be elevated, the top sheet being thereby released to move forward upon the blanket of air. This movement is also accompanied by a downward moveent of the closure 25 which opens the lower end of the pipe fitting 24 thus breaking the suction in the pneumatic system which releases the top sheet. As soon as the cam 33 has again operated thelever 29, the closure 25 is forced into closed position when the mechanism is ready for another operation. 1 i
