See Espacenet advanced search on Harold Edward Sherwin Holt. Via this search there are 92 patents filed, 49 of which were filed in his native Britain, beginning in 1894 with electricity and instruments, touching much non-aero, then segueing through aiming and other military applications before getting into aviation per se, largely though not exclusively via illumination devices attached to wings, by around 1912. His work with parachutes seems to have developed after our years of primary interest.
