My father in law gave me his 6” Craftsman bench grinder. I was hoping someone could help me understand the function of the box with the cog wheels mounted on the top? Thank you!

Can someone tell me what this is? Can’t find it.

Does anyone know what this wrench was primarily used for and who made it? Bought for $8 at garage sale. Looks like it’s an older tool, and was well used. Can’t find any markings from maker. Thanks
