New Departure Controller coaster brake hub. This is an early one, notice the brake arm on the driveside(no cog affixed in the photo). It is also takes straight-pull(or sometimes referred to as button head) spokes.
New Departure began in 1888 producing doorbells and by 1898, they produced their first bicycle coaster brake hub. They later were purchased by General Motors in 1916. New Departure hubs, the later model D hubs particularity, were known for their great modulation in braking and were found on popular Schwinn Phantoms bicycles.
(from researching, this appears to be the only photographs of the New Departure Controller hub online. I hope to keep putting more weird and esoteric bicycle parts online)
