Okay, I admit it; this one is an utterly premeditated teaser. I'm evil that way. Also, I'm interested to see who, if anyone, will know/guess it. So have at it in the comments and make your best guess; I'll refrain from clearing comments for publication until I blog the answer.
Y'know, looking at it again, it's possible this may be too easy...
It is a take down framing square.

Take-down square?
ReplyDeleteOnly thing i can think of that I've seen with adjustable measurements from one axis and not the other is one of those spade bits that everyone picks up at a garage sale because the tool is in pristine condition and then later realizes it is because nobody ever takes the time to set it up properly to use it.
ReplyDeleteAdjustable auger bit?

Looks like a adjustable spade bit for a brace but I'm sure I'm way off
ReplyDeleteI just noticed that I gave the wrong patent in my earlier post. It looks like the Eagle take down square from Aug 18 1914.

The cutting wing on my only adjustable auger is bummed beyond repair. Hope yours (many I assume) work better.
