I remembered reading about it in a CU report on coffee makers in the early 60s. It has a 4 cup capacity. Bought one years ago. Basically, the water goes in a can in the bottom with the percolator-style pump, then a plate above it and the coffee basket and spreader above that. As CU said, even though it does not look like a drip coffee maker, it meets the definition of a drip coffee maker in that the water only passes through the grounds once even though it is "perked" up onto them. If I can find the thing, I will send you the directions. 

The Dulane Coffyryte was an electric drip coffee brewer from the late 40s into the early 50s that was one of the early electric drip devices that preceded the Revere pot that Hans found.  I offer the link as a research resource. I have never found one of the Coffyrytes, but I have magazines with the ads. It, like the Revere Ware copper clad stainless steel deep well kettle, seems to be one of those housewares that was beautifully designed, but remained scarce and so is hard to find today.

Dulane was the company that made the Fryryte deep fryer.
