Greathead invented and built his own design of a shield as the contractor for that project, under Peter W. Barlow who was the engineer. Since Beach was a patents lawyer, it is likely he discovered the 1869 Greathead patent and the patent application by Barlow from 1864, using an imitated Barlow's patent design for engineering the PTS tunnel design.
