Abstract
Propeller with blades of variable position to interchangeable characterized by establishing a nucleus determined by two bodies of frusto-conical configuration and coupling with each other, each of which has in its part measured a well-conical drill to pass the drive axle some smaller diameter fices that surround the central perforation allowing the passage of adjustment and pressure screws and half-jaws equidistant from each other and which are complemented by those provided in correspondence on the other body that forms the core, completing the assembly with a large nut with play in the threaded end of the drive shaft and with some blades each of which is constituted by an arm or fin that ends in the area through which it must be embedded in the core in a conical terminal that penetrates any of the jaws with which it coincides in structure and in whose housing it is firmly held by the pressure exerted by the coupling and adjusting screws, the nut provided at the end of the drive shaft cooperating with this same function, which is what definitively secures the assembly once mounted.
