Here is a picture of a 1917 Schwinn using the truss frame.
Harley Davidson also had a truss frame from 1917-1921.

I know I have seen a Henderson from that same period with that frame. Henderson as you know was a bicycle company turned motorcycle company that was bought out by Schwinn. Althought the bikes have an interesting look they are very heavy. The only time I have seen Major Taylor on one of these was in an ad where he raced it for publicity purposes. He preferred the regular double diamond model from everything I have seen and read.
