Manually controlled variable pitch propeller

Abstract

Abstract PROVIDED IN EACH OF THE FLAT SURFACES OF SAID SLEEVE HAVING THE ECCENTRIC STUD ON THE FLANGE OF SAID BLADES ENGAGED THEREIN WHEREBY AS THE SLEEVE IS MOVED LONGITUDINALLY WITH RESPECT TO SAID HUB THE ANGULAR PITCH OF SAID BLADES CAN BE SIMULTANEOUSLY ADJUSTED TO ANY POSITION BETWEEN A FORWARD DRIVE POSITION AND A REVERSE DRIVE POSITION, H. ONE END OF SAID SLEEVE INCLUDING AN EXPOSED CIRCUMFERENTIAL GROOVE THEREIN SPACED FROM THE EDGE OF SAID SLEEVE, AND I. A MANUAL CONTROL LEVER HAVING A YOKE AT ONE END DISPOSED SO THAT SAID YOKE IS POSITIONED IN SAID SLEEVE GROOVE FOR LONGITUDINALLY SHIFTING SAID SLEEVE AND VARYING THE PITCH OF SAID PROPELLER BLADES WHILE THE ASEMBLY IS BEING ROTATED BY SAID DRIVE SHAFT. 1. A VARIABLE PITCH PROPELLER ASSEMBLY FOR MOUNTING ON THE DRIVE SHAFT OF A MARINE ENGINE COMPRISING: A. A TUBULAR HUB MEANS ARRANGED FOR SECURING ON THE DRIVE SHAFT FOR ROTATION THEREWITH, B. SAID HUB MEANS HAVING A RADIALLY DEPENDING FLANGE AT ONE END THEREOF, C. A PLURALITY OF PROPELLER BLADES, EACH BLADE HAVING A MOUNTING SHAFT AND A FLANGE AT THE END OF SAID SHAFT OPPOSITE SAID BLADE, D. THE OUTER SURFACE OF SAID FLANGE HAVING A STUD EXTENDING OUTWARDLY THEREFROM WHICH IS ARRANGED ECCENTRIC TO THE ROTATIVE AXIS OF SAID BLADE SHAFT, E. A PAIR OF BLADE MOUNTING RINGS HAVING A COMMON INTERFACE AND ARRANGED TO BE FIXEDLY ATTACHED TO THE OUTER EDGE OF SAID HUB RADIAL DEPENDING FLANGE, F. A PLURALITY OF RADIAL BORES FOR SAID PROPELLER BLANDES DISPOSED AT THE INTERFACE OF SAID PAIR OF RINGS, SAID RADIAL BORES BEING EQUI-ANGULARLY SPACED AROUND THE CIRCUMFERENCE OF SAID RINGS AND SIZED TO ROTATIVELY MOUNT THE BLADE SHAFTS THEREIN, G. A CYLINDRICAL SLEEVE ARRANGED TO BE SLIDABLY MOUNTED ON THE OUTER SURFACE OF SAID HUB MEANS AND ARRANGED TO HAVE A FLAT OUTER SURFACE CORRESPONDING TO THE FLANGE OF EACH OF THE PROPELLER BLADES, A LATERALLY EXTENDING GROOVE BEING
