Old Vintage Delta, New Problem

The quill in this tailstock is extremely difficult to crank in or out. I took it apart as much as possible and had to beat out the quill from the back using a wood dowel and a hammer. It acts as though the quill lock is tightly engaged. The quill slides in easily until it contacts the lock.
Does anybody know of the quill lock collar that the black arrow points to is supposed to float free when the handle is loose or removed?
Thanks.

Go over to vintage machinery and do a search for delta, the schematic for that lathe/tailstock will be there. Then you can compare what you see in front of you with the document, and determine if something is awry. I have an old rockwell myself but the tailstock is a different design.

A schematic is what I’m looking for.
 
If you re-attach the locking handle and shine a light down the bore of the tailstock and rotate the locking mechanism back and forth you should
be able to identify the problem. As Gary mentioned above there is most likely a cam or eccentric lobe that engages the quill to lock it in place.
