I’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.
I trust that you cleaned and lubricated the slide under the spring, too. I wont see a Universal until September. Hopefully Fritz or someone else will have an answer before then.
Yep, that’s right, B doesn’t snap back into position. The spring that pushes B back is fine.
Thanks. I’m still tweaking it.
Do you mean that (B) doesn’t snap back to the stop after the carriage is rolled forward?
I think the other spring is fine.
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.
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!
