Large Whatsit Replacement Wrench Jaws

[wvtools]

I am listing these 3 replacement jaws on Ebay and have no idea what wrench they may have fit.

Thanks,

They look like jaws for a three jaw lathe chuck.

Yes, they do kind of look like lathe chuck jaws.  I will have to go through some of the old jobber catalogs like Jackson & Tyler tomorrow and see if I can find a match.  I should have thought of that.  I just had adjustable wrench on the brain.  Thanks.

Chuck jaws are usually precision machined - these look to be cast, and much more primitive... However, as the teeth are offset from one jaw to the next, it is likely they are set 120 degrees apart...

Similar are found on ratchet diestocks, to centralise the pipe being threaded

I agree with Billman, I was thinking exactly the same thing, but then I couldn't see how those jaws could grip pipe, so I kept pondering?! I suppose they could grip some sort of flanged fitting?

Are the little triangular teeth the same from jaw to jaw?  Or are they offset from one to the next.  The reason I ask is that it might be a set of jaws for grabbing a threaded end of a piece of pipe.  For making close nipples maybe?  They sure look like lathe jaws, but could they be from a pipe threader machine?

Could be the jaws for a modern pipe cut off machine to grip and move the pipe to a precise length
to be cut, There would not have to be too much pressure to move the pipe lengthways.

We are having a party for my mother-in-law's birthday today, so I will have to look at them tomorrow.  I looked in some old pipe tool jobber's catalogs that I have.  It was kind of hard to see in the pictures, but the jaws do look more like the jaws on large industrial pipe threading machines than the lathe chuck jaws shown in machinists' jobbers catalogs.
