Unique Triangle Sprocket Featherstone, 1896?

[carlalotta]

I got this incredible 1896(?) Featherstone bicycle for Christmas. It has a very strange triangle sprocket with an off-set rear sprocket. The sprocket system has a three to one ratio. When the peddle sprocket is rotated to the low point the rear sprocket is off-set to the rear to keep the slack out of the chain. I have never seen anything like this. It is not homemade. Anyone have any information on this bicycle?

Nice! I have a 93 Columbia (project) Century with an elliptical sprocket, an 1898? IDE (also project) tandem with curved spring cranks, a dual position elliptical Rocket Sprocket, I've never seen a triangular one...

Very different and unique to say the least. I'd love to just see a video

of that pedaling on those stands just to get an idea of how the whole

contraption works.......
