You do realize that's nothing, right?
A few stats for the “Oriten:”
Built in 1896
23 feet long
305 pounds
Required two miles to get started
20 mph to remain upright
Fixed gear; no brakes
45 mph cruising speed
More info: July 1992 Bicycle Guide

Apparently history is silent on what happened before you got that thing up to 20 mph!

Most cyclists of the day actually removed the brakes from their bikes because they were considered “feminine.”
“Braking” this thing involved putting the biggest, heaviest rider at the back. The “brakeman” would just start resisting the pedals with all his weight while the guy steering tried to stay on course.
The subtitle of the article is “truly unsafe at any speed.”

Each crank has two rings. the front rider's ring (lets say 42) turns a synchronizing ring of the same size (42) on the crank immediately behind it, and then that crank has a (lets say) 48t ring that turns a 48t ring on the crank immediately behind it, and then that crank has a 52t ring that turns a 52 on the crank behind that, which has a 56t ring, and so on.
does that make sense ?

Exactly right smd4
here's a bike I'm going to restore. I think I'm going all 753 tubing, full Super Record, with Martano rims and Clement Setas. What do you think ?

Putting aside what mpetry912 brought up since I haven't worked it out...
How can they be pedaling at the same rate when they each have different gearing ?

Anyone who has tried a tandem ... you don't have to pedal at the same rate ... the driver or stoker can do all the pedaling and the other can try to fight .... but it is like braking on a brakeless fixie. You have to fight to push back on the pedals ... or you can just hold your feet up and let the other guy do all the work.

How did the frame or the wheels not break? Does the captain have a whistle in his mouth?

The article says it was on display at the Henry Ford museum. I wonder if it still is?

It could be phased by 1 to 1 progressive as posted above. Except for the rearmost guy, as evidenced by the photo. He marches to the beat of a different drum if you will.

I'm pretty sure that, as described above, the gear ratios of each crank to the others is 1:1. The best explanation I have for increasing chainring sizes, rather than just a larger last chainring, is that as you go back each chainring has more torque on it, so larger chainrings make it less likely to shear off teeth. Maybe the rear cog was built from a higher quality material?
