The idea seems to be to have a complicated set of bowstrings on a kite which improves its concave curvature for flight.

A later patent by Robinson builds on this one and refers to it.

  • Inventor location: 105 Franklin Road, Harrogate, County of York
  • Inventor occupation: Engineer

This is a rare case in which the IPC category looks quite different from the CPC category.example
