uni-i-gripper-opener-springI’m struggling with the automatic gripper on my Vandercook Universal I. I took it off, cleaned it, oiled it etc. but it still doesn’t jump back in position to open the grippers automatically. I wonder if the spring that sits between the side of the bed and the lever is not the cause.
Can you tell from my photo if this is the case? I already did send an e-mail to Fritz Klinke to see whether he’s got a new spring.

    Yep, that’s right, B doesn’t snap back into position. The spring that pushes B back is fine.

    I did pull the knurl pin out, and it functions once beautifully, after that the latch doesn’t return to its initial position. I get the impression that the spring that I circled doesn’t push the lever back enough. By the way, nice clean layout!

  3. It’s the other spring that work with the auto gripper function. You may have inadvertently pushed the knurl pin (A) down, which keeps the spring compressed. To release the pin, give it a slight twist while pulling up.
