New Departure Coaster Brakes

New Departure was for many years one of the top brands of coaster brake. Most models use a stack of discs, alternating steel and bronze as the braking "shoes." Every other D-28 disc in the stack has three tabs that engage slots in the hub shell. These discs always turn with the hub.
The alternate D27 discs have flatted holes and engage the disc support sleeve (D22) These discs do not rotate.
When the brake is applied, the thread in the Driver (D2) presses the Clutch Sleeve (D3) against the Brake Clutch (D6) which in turn presses against the stack of discs. The friction between the discs slows the bike down.
When you pedal forward, the thread in the Driver (D2) pulls the Clutch Sleeve (D3) against the narrowed section of the hub shell. The serrations in the tapered end of the Clutch Sleeve grab the matching surface of the hub shell interior.

Here are some images from the 1938 Island Cycle catalogue.
