I have recently taken two Universal I presses out of storage and am getting them going for the first time so, I’ll be making quite a few postings here in the next few weeks. My first question is regarding the gripper assembly. One of my presses is a later model Illinois Tool Works press, serial #29465 dating it to 1972, I believe. The gripper cam on the press is connected internally to the impression cylinder instead of lifting out with the entire assembly as I have seen in the past. The gripper cam was initially stuck so that the grippers were in the up position. I’ve worked the cam loose but the spring that sits at the far end of the cam on the operator’s side of the press is remaining compressed so that there is no tension in the cam to raise the grippers. My manual is not particularly helpful, as the illustration simply cuts off mid cam spring.
The second question is regarding the trip/print flipper (techinical term?), which is stuck in the up, trip, position. I believe the adjustments of the various rods/arms that actually engage the flipper are a little off but that is not really the problem. Nothing is impeding it from going down into the print position in those adjustments. Nevertheless it is stuck. Once again the manual is not particularly illuminating. If any one has any insight I would be extremely grateful. I move on to a Uni I with an automatic carriage next.
All best and hello,
