The second elevator consists of two levers, connected by a bolt and cushion spring. The short lever carries a roller which operates on cam No. 6. The short lever operates the long lever, to carry the matrices from the first elevator to the distributor box. On the outer end of the second elevator lever is the bar plate and second elevator bar. The matrices are held on this bar by their combination teeth. On the right-hand end of the second elevator bar plate is a stop pawl. The stop pawl prevents the matrices being pushed too far to the right during the transfer from the first elevator to the second elevator, and keeps the matrices from striking the distributor box bar when the second elevator is being raised to its upper position.
When the elevator is at transfer point, the roller should be free of the cam. Adjust by the nut on the connecting bolt which connects the two levers. This is to assure the elevator seating in its proper position on the transfer channel to receive the line of matrices from the first elevator. The machine should be in normal position, the automatic stopping pawl resting on the upper stopping lever, when making this adjustment. With the machine in normal position, adjust so the connecting bolt is free to turn, with no end play between the head of the bolt and the adjusting nut. When this adjustment is properly made, and the machine is turned to transfer position, the roller will be free of the cam. When in normal position the second elevator bar will align with the bar of the distributor box. Unless the connecting bolt is free to turn when the machine is in normal position, the second elevator will not be properly seated in the distributor shifter guide, and the second elevator and distributor box bars will not align.
Second Elevator Starting Spring
Located just inside the machine frame, near cam No. 2, and connected to the short lever of the second elevator, is the second elevator starting spring and rod. When the second elevator is at transfer point the adjusting nut should touch the spring. The spring is to start the elevator down and prevent sticking at the distributor.
The most tension is on the spring when the machine is at normal position and as the cam revolves, the second elevator cam lever will get its proper movement when going to transfer position. The spring also causes a steady movement of the second elevator lever when going from transfer to normal position. This adjustment has become obsolete on the new machines.
Second Elevator Safety Catch
On the end of the second elevator lever, near cam No. 10, either beneath or at the back side of the shaft, is a projection for the purpose of preventing the elevator from falling and being damaged should anything catch or hold the lever momentarily from following the cam. This projection engages with a safety pawl on the machine frame. This pawl must be released before the lever roller can rest on the cam. When the elevator descends at its regular time, the safety catch is held open by a raised piece on the surface of cam No. 10.
MAIN CAMS
The main cams control the movements of the various levers of the machine and their operations are dependent on these cams.
The assembling and distributing mechanisms alone are independent of the main cams.
