All the rest were assigned to the Fowler Car Co. It would be nice to
see what they actually covered, and if there were any additional
patents issued in the U.S. I would suspect that by 1913, when the car
side patents were applied for, the basic steel framing was all prior
art, and the only thing left to patent were improvements in details.
It would be interesting to see what they were, never the less.

Large city (Carnegie Library of Pittsburgh, for one) or University libraries often have US and Canadian patent files, either in book form or on film.
