Deckel drawbar for jig boring head confusion....

I had two Deckel jig boring heads and what the first head had for a drawbar appeared the same as the first link-

But due to cost I emailed Singer to see if I could buy just the S20 drawbar by itself (figuring I'd make the thrust ring part) and got the below link to another drawbar setup.....which I don't understand....what the heck is the spring and the other two parts all about ??

Trying to fix those links for yah, Boss. Hang on a mo.

OK. Seems to have worked. Double-check me that they still reach the correct destination, please.

Then fix your original post, and delete THIS post as a mere distraction. Or I can delete it.

Sometimes one has to edit and shed all that tokenish tail-code overhead.

Commonly, it is session-unique and not "portable" to the next seeker and HIS browser's "visit".

Well, I have a guess - the clue is the word "sicherheitseinrichtung".

I had a High Speed Head of the newer kind. It had a safe type of drawbar tensioning.
I had to use an Allen key, which would be pushed out by a spring after use.
So you couldn't leave the key in by mistake and get it stuck in an eye or whatever.

This looks like the same arrangement.

Too lazy to Google just now. "security enrichment" literally.

That fits. Especially if there is a one-eyed Deckel operator out there. Or so he became.
