No. 4 Trip/Print lever

I’m hoping this is a simple question. What part of the trip/print lever on the No. 4 maintains the lever arm in trip? When I depress my lever into trip and the arm moves upward, but it doesn’t stay engaged and immediately falls back down along with the trip wedge (back into print). I’m not sure what to adjust to keep it engaged. Thanks!

    It may be that the lift arm block *(MS-276) wasn’t in the correct postion when the screw the holds the lift rod was tighten. Retighten in trip mode.
    Also, check the pin (MS-170) in the lift arm block that contacts the left handle (MS-138). If thepin is flat rotate it. Or build up iwth tape like we did on the Silver Buckle press at Hamiltion in November.

    I have a CM-37 ball knob. Email me.

    one more picture to show that the knob (missing) is down as far as it can go. There’s no more available excursion there.

    I addressed tightening the internal nut on the short bar and now the lever stay in trip, but I have another issue. When the lever is in trip (and is pushed as far as it can go), the wedge is only elevated about half way. The good news is, that it doesn’t interfere with how the cylinder works. The wedge is up far enough for the trip roller to proceed unhindered. I’ve adjusted the lift arm and it is up as high as it could go given the available excursion from the lift lever. Should I just let it be since it works?

    Thank you Paul, this is exactly the information I was searching for. I’ll let you know how it goes.
