tandem with odd details
A really nice photo of an 1895 4-man tandem:
http://flickr.com/photos/nmsi/254755...57605170495840 As the caption mentions, the captain was the co-founder of Rolls-Royce. (The site calls the quad a "duad" because the cursive "Q" looked like a "D" to someone.) Here's the large version of the photo, with a few details marked: http://home.comcast.net/~carlfogel/download/quad.jpg (The large version is so big that tinypic reduces it--3504 x 3045 pixels. The front wheel should just fit a 1280 screen.) Like most tandems, lots of spokes--56, front and rear, with two broken spokes visible on the rear. Nice lamp for night rides. Odd gearing arrangement: two small front sprockets using small chain on sharp-toothed inch-pitch chain, connecting to two slightly bigger sprockets with much blunter teeth and heavier inch-pitch chain. The final drive off the big sprocket switches back to sharp teeth and small chain. Cheers, Carl Fogel |
