I would guess they are for putting a flare on copper pipe.
It is a Lead Pipe Expanding Tool. A friend has one exctly like this, and I found the following on the internet:
1. The lead pipe expanding pliers is a tool which has been devised to do the work of the several sizes of turn pins. By pressing the lever handles together, the conical end opens and spreads the pipe. The end of the cone is knurled, which tends to prevent the expanding cone from slipping out of the end of a heavy pipe in expanding it.
It will be seen that as the cone opens, it forms an ellipse instead of a true circle, and to make the expanded end of the pipe perfectly round, the expander must be constantly turned as it is being used.
They are still for sale even today:
