Odd (early?) chain construction

[DelombardR]

This chain is on a ca 1884 Mascotte tricycle.  The chain is comprised of steel cylinder sections connected by U-shaped rods, flat plates, and tiny cotter pins.
It has a tendency to roll off the sprockets and jam. I have tried re-aligning the front and rear sprockets and also measuring the pitch to see if it is 'stretched'.

Has anyone else had experience with a chain like this?

It looks like a variation of the Morgan patent chain. Placing a straight edge alongside the sprockets will tell you if they are actually in alignment. It might be my imagination, but it appears that some of the bushings are oval shaped instead of being concentric. The chain shouldn't be tight.

Thanks, Craig!  I see now.

It might take a little work to get the two sprockets into alignment. They are slightly non-planar. I had rotated the mechanism holding the front sprocket so the lower edges are more aligned.  I have to await better weather for more road-testing! 

I have thought of replacing all those cylinders if they are warped and have lengthened the pitch.
