Just purely a guess and a similar facsimile, but this cat Alfred H. Worrest looks to be the designer of the Infallible(Oct. 16, 1911): http://www.google.com/patents?id=fd1jAAAAEBAJ&printsec=abstract&zoom=4 . Here is an earlier version submitted in July 1910: http://www.google.com/patents?id=1ap9AAAAEBAJ&printsec=abstract&zoom=4 . Hopefully some can set me straight and confirm or deny.

Kind Regards,
