A primary object of this invention is the provision of an apparatus for holding and positioning a workpiece with respect to a grinding surface on the grinding wheel of an electrolytic grinding machine.

As near as I can figure it's an adjustable work holding fixture for a surface grinder. Mount it on the electromagnet table and swivel, rotate, pivot, & slide adjust the work piece to the postion or angle you need to gring it at.

With a whole lot of 'legal speak' basically saying that in 5,000 words or more.

I think it would be used for custom grinding step drills, end mills, and other custom shop tooling.

But.... I could be wrong. It could be for grinding electrolytic machine parts.

By "Electrolytic" I believe it's a machine that looks like a surface grinder but is an EDM with a graphite wheel.We a couple at one time.The brand was Elox.We never used anything like the device in the patent as we had specific fixtures to do the limited number of tasks the machine was used for
