Patent RU-1909-41312

This application received provisional protection certificate 41312 when it was filed in 1909; we have no evidence that it was granted.
Most likely it descends from one of Ruthenberg's German filings pertaining to windwheels, such as Patent DE-1908-227004, which seem to have many international correlates.
