This is an addition to a patent filed 1909-02-06 which we would designate as Patent FR-1909-409039. Said parent patent is one in which the bibliographic data on Espacenet is very patchy, and the original is missing. It is still searchable via patent number and the IPC and CPC comport well.
This addition also refers to a Belgian filing dated 1909-02-06. This latter may likely itself have been a “perfectionnement” within the Belgian system
