Wow!
That's very nice!

And in 1907 you could buy an after market springer to attach to your fork.

Amazing spring fork!

This 1907 article suggests Racycle offered both spring forks. When was the Iver Johnson fork introduced?

Interesting history.

Here you go.... I knew I had seen it on here, just took awhile to find it! The patent for the Racycle dual leaf:

Patent searching can be very informative, it appears that Mr Schenck was also the filer for the triple spring fork:

Very accurate patent drawings.
The drawings could be converted to 3-D CAD drawings if there were measurements.

Even more interesting, Mr Schenck applied for patents on the same date March 18, 1907 for both designs.

I'd also found a patent for Racycles "New, Improved Crank Hanger" dated to 1906 (file date) while it had actually been being sold since 1904!
