🔎 UNIDENTIFIED Cast iron crescent shaped whatsit

[robertk]

I found this at a home site dating to the late 1800s and early 1900s. It appears to be cast iron, fairly heavy. I don't recognize it as part of a cast iron stove (though I have found plenty of stove parts here). Maybe a part of a car, or part of a piece of farm equipment? Does anyone recognize it? Here are photos from all angles, plus size references. Click to enlarge any of them.

#5-possible foot pedal, tractor.

#5-possible foot pedal, tractor.

Apologies, that particular photo is misleading. I balanced it against the spike piece to take a photo of that angle and it’s not obvious. Here is that same angle without the spike piece holding it up. I will edit the original post as well.

Maybe from a crank (wind) out window.

Maybe a stop for some type of winch?

I think that is close? I would say the latch to hold the brake pedal down on a tractor?

Some type of dog/pawl to engage a crank or ratchet. Possibly for a large chainfall.

No idea, but it sure is an interesting (relatively complex) casting! 😀

I think this line of thought — that it’s a dog or ratchet or latch type thing — makes a lot of sense.

I don't know what it is.
Nobody knew what this was either....

I thought this might be some kind of latch (or slide bolt?) too.
Do you think they might fit/go together? 🤣

I guess anything is possible.

 

[robertk]

Not an exact match, but it looks similar to the ratchet arm on this old jack (found online):

I wonder if the little "tooth" on the end of my find is really a separate piece that has just been fused by rust, and maybe was able to move back in the day? Maybe I should dump it in Evaporust...

Another clue is the hole pointing towards 8 o'clock in the first pic is beveled for a countersunk screw.

It's hard to tell. The holes were both full of dirt and rust when I dug it up, and I used the tip of one of the dug nails to clean them out. I can't say for sure if it's countersunk, or that's just how the rust makes it look.

It looks countersunk to me too, but I'm wrong a lot. 😏
It's still (likely) a screw hole--just a question of flat head vs. round/pan head.
