Ingraham ,1879 , used a similar method to this Ansonia N movement, while New Haven, and others, used a 3-leafed washer, compressed by a pin through the centre wheel shaft, with a raised circular wall to keep the pin in place. I prefer the Ansonia / New Haven method.
Obviously both have stood the test of time, as we see them still working well to this day. The clutch or friction washer type featured on the New Haven may cause trouble if an oversized diameter pin has been forced into place, kinking the leaves and causing tension to be lost in the hand setting. The trick is using a smaller diameter pin and relying on the leaf tension and raised circular wall to hold our pin in place.
So why not remove the risk altogether and go with the Ansonia system..as you can see, it can be cleaned thoroughly. As mentioned, both have lasted and performed outstandingly; perhaps there is more skill involved in maintaining the New Haven system. Maybe the simple design and reduced manufacturing costs made Ansonia the outright winner!
