From google patents: "26,289. Coma, C. Dec. 4. Screw propellers.-A number of screw propellers or blades arranged on a boss are so disposed with respect to each other that they are close together and overlap as shown in Fig. 1. It is stated that by this arrangement the water is acted upon by successive blades without producing whirls. . . . [Reference has been directed under Section 7 of Patents &c.

This patent essentially matches Patent FR-1908-397263 and is therefore quite likely also a descendant of designee Patent BE-1907-12-11 Clément Coma. The priority date reference is found only on the French patent.
- Inventor locations and occupations: Coma: At time of provisional submission: 9 rue Brémontier, Paris, Seine ; at time of complete spec: 17 rue Carnot, Montmagny, Seine-et-Oise ; Doctor
