The details in the pictures are hard to see.
From the bottom, there is a pointed key sticking out of that outer shaft.
Is that key the same piece as the square shaft the hammer hits? So if it's
raised the square shaft will also be raised, and the hammer can hit it down
without shearing the cotter pin holding that shaft in?
How does the ratchet work? Does it automatically step with each hammer
blow? Or is it just spring loaded so that the outer shaft can rotate in
only one direction?
Is there any chance the hammer was designed to swing outward (180 degrees
from the picture) when it was being used? i.e., instead of intended to hit
that square shaft?
The outer shaft seems to be on a pivot from the base plate. Is that
correct? Could that pivot be what allows the ratchet to auto-step as it
moves up and down slightly?
The hammer head alignment doesn't seem like it will be flat with that
square shaft when you lower it. YOu don't have a picture with the hammer
head down. Is that correct? That and the fact that it seems to be a very
large hammer for a small delicate square shaft makes we wonder if it
actually was intended to hit that piece.
Ah, I wonder if the intent was for that floating shaft on the end to be a
pivot for the rest of the jig. The key and the hammer might be used to
wedge that piece into a center hole on the work piece. The rest of the jig
could then be pulled around in a circle with the ratchet preventing it from
going backwards. The adjustable shaft in the center would then be the tool
that was run around the outer edge of whatever the thing was, perhaps to
bend a band around it, or to seal a lid on it or something like that?
Or, maybe, the hammer was only used to remove the jig from the hole it was
stuck in by taping on the square shaft. And when turned outward, the
hammer would act as a lever to pull the jig around the work-piece.
The "work-piece" would be something round with a hole in the center that
needed something done to the outer edge. Wheel? Barrel? Gear?
