Different from Silverston's other patents which were more aeronautical. This one is more mechanical. It has to do with a shaft driven by a motor. The shaft may connect multiple motors to multiple propellers or propeller blades. The phrase "fluid displacing" may mean a motor driving an impeller/propeller that moves air fluid around, as opposed to the fluid displaced by the existence of the motor.
From top section of patent spec text, via google patents OCR, compressed:
- "This invention relates to fluid displacing motors, and has for its primary object[ive] to provide an improved fluid displacing motor which shall be light, durable and which can be economically manufactured.
- [and to provide:]
- improved construction for fluid displacing motors [such that] the usual fly-wheel may be dispensed with.
- improved means for obviating the formation of eddy currents and thereby increasing the fluid displacing capacity of the propeller.
- improved means in a fluid displacing motor for counterbalancing the gyrational effects produced therein.
- an improved combined cooling jacket and propeller.
- an improved construction, combination and arrangement of parts for a fluid displacing motor.
- Tech classes: CPC B64C11/48 Units of two or more coaxial propellers; and CPC B63H5/10 Arrangements on vessels of propulsion elements directly acting on water of propellers of more than one propeller of coaxial type, e.g. of counter-rotative type
- Inventor location: Milwaukee, WI, US (FIPSloc=55079, imputed by HistPat)
- Inventor signed/dated the spec on Sept 21 1909, but it wasn't recorded as filed at patent office until Oct 14 1909.
