I got the following from my dads collection of stuff.

I have no idea what they are used for. They are about 4 inches in diameter and 1 inch thick. The one with a straight knurl on one edge has a keyway in the center hole, so I assume it is a driven wheel. Therefore I guess something was pinched between the two and pulled along. Ideas?

It looks like a knurling tool for making the guts of old style shower heads. the lower part could be a gage for the housing that holds the knurled part.

Thats just a guess but I bet I could use it to make a brass shower head.

He wasn't a sheetmetal mechanic was he?If so they might be wheels for a Pittsburg machine.

That's almost certainly what they are- wheels for a sheetmetal edger/tipper.

The one's kind of sharp, but "shearing" wheels were available for the same machines.

From the evidence in the photos, they appear to be some sort of BUG CRUNCHERS :D
