That is a nice design.  I've got one, and hadn't thought about the fact that it would work in tighter spots.

I take it the screw is there for storing the wedges.  I can't recall how mine stores them.

[UncleBill]

That's right.  The screw just holds the wedges inside the socket so it stays together as a set.

Also I have it set up incorrectly in the 3rd picture.  Your supposed to insert the broken bolt through the end hole and then insert the wedge through the side hole and push down until it locks on the bolt threads then crank the ratchet to free the bolt.  I tried it on a loose bolt and it grips pretty tight, so it seems like it would work fine.

My Proto version has a clevis with a spring loaded ball to keep the wedges in the housing. I have owned mine for over 35 years.

I like it,  nice find. I got a chuckle out of the description "works close to the dash". in 1936 I guess that they still called the firewall the "dash board" ... horse buggy terminology. The thing inside the car was the instrument panel.

Luckily the original owner was very descriptive on how it worked.  It was a good thing because when I first saw it I couldn't really figure out what the use was considering it looks like your regular socket at first glance.
