I would think this piece is a replacement for the original screw adjuster. the back end should be threaded to accept the threads of the slide hammer. No need to weld it to the slide hammer unless you wanted a dedicated tool. My slide hammers have a thread on the end and each attachement is held on with a nut; an axle puller flange, and an L shaped fork as well as bearing pullers.

Speaking of the L shaped fork, you can use such a bracket to hold the timberlok screw and yank with the slide hammer. I will try it in the next couple of weeks if not this weekend.
For broken off nails, I bought and old fashioned nail puller. It's over 100 years old probably. It has a handle that extends and a foot attched to one of the jaws so as you apply force to the handle, it acts to clamp the nail more while pulling it. I haven't used it much yet, but in the next month will be denailing some timbers and trying it more extensively.
