The patent narrative says it is a material holder for a grinding operation. Quite a bit more elaborate than my bilateral vice on my drill press, but the same theory.

except that there is nothing to hold workpiece. I've had two machine shops look at it and they had no idea. That was before i found the patent pdf.

I would think it is for a vertical round billet held in place as in figure 3. Figure 5 shows the degree to which it can be accurately rotated or supined to produce different angles on the billet. Just a WAG.
