That's an old school percolator. That kind you set on a burner to heat the water, goes up a tube spurts out the top of the tube - visible through the lens at the top, then drips over the coffee grounds in a filter type cup. Best coffee ever, next to what you can get out of a coffee press.
Some are stainless, some aluminum with the enamal coating. Percolated coffee tastes a hell of a lot better than anything brewed via a "drip" maker.
Sorry you seem offended, that's how the thing works, find a nice video on youtube or such.
