What are the parts of a horizontal windlass?

Looking at a modest windlass used to raise the anchor of, say, a mid-sized motor yacht, we'll have some kind of electric motor to drive it. This will usually have a foot switch that actuates a solenoid to run the motor. The motor will drive a gear or gear set to spin the main drive shaft. This will drive the gypsy (which is used to engage the chain) through a clutch of some kind. There will be a locking mechanism of sorts as well as a manual recovery option, which will allow the anchor to be "ratcheted" or "hand cranked" and recovered. A housing of some kind will cover or enclose most of the working parts.
