Found this in my dad's stuff. One end it threaded, looks like 1/2 pipe thread but I didn't check it. The knob and shaft slide in the body and no
cutting edge on the tapered part. Not for flaring. I'm thinking it threads on to a pipe and struck with a hammer to smooth the cut end. The only
markings art show in the first picture.

The use of a pipe cutter with a rolling cutter wheel produces a ridge internal to the pipe where the metal deforms inward. this is often removed with a reamer, but could be easily wedged outward using that tool. Increasing the flow, reducing turbulance, and if used on pipe with wires (schedule 40 pipe) could save insulation shaving and binding. Jim
 
Interesting. Looks built heavy enough to be a tool, but if it's to be used as a tool I would have thought you'd see some witness of hammer marks on the head, or a ring around the cone where it struck the inside diameter of the pipe. I'm also surprised the cone would taper down so narrow, when it would only work for one pipe size.

It looks almost identical to a check valve we had on an old well pump - it also didn't have any sealing ring, and relied on gravity to seal the spool.
 
I think is is a swage tool as Jim suggested but for another reason. A NPT female swivel requires a small 45 degree seat on the I.D. of the male end. If a NPT female swivel is used to connect to a pipe the end of the pipe must be square and have a seating surface. I have used a 45 chamfer tool in a drill but that tool would be more accurate,, IF that is what its used for,,,,
 
I thought of that too, Butch. But I don't know that it could form a wide enough seat without cutting. Next time I get over there I'll bring it home for research and trials. I posted it on a FB old tool group and at least 20 said it's a rafter/stair gauge for a square.
 
It is NOT a stair gauge for a square. The slot in that gauge would not be rounded. The sides would be flat so they could securely grip the square.

I do not know what it is. But I do know what is is not.
 
Ha, you got whacky responses on FB because there are so many whacky people on there. One will say something, then others who have no clue jump in and say... yeah thats it.

Crazy
 
I blew up the pictures and it looks like PARKER in the third one so probably for pneumatic or hydraulic work. There is no nipple on the cone, just looks like it from the shadows.
 
The Parker name would suggest a fluid power fittings and/or tooling application. Maybe one of the resident Googlers with time on thier hands will search a while.
 
Since there is no nipple on the cone, I will post my first idea, a de burr tool for rigid conduit. The cone would blunt the sharp edge to a smooth surface.
 
I say a flaring tool of some kind for possibly installing the backup ring behind a flared line on a flared fitting or line for higher pressure hydraulic pressures. Or the double flare at the end of larger lines. If it screws down instead of being hit it might not show any hammer marks on it.
