A portable implement for providing a source of electrical energy, where the implement has an electric generator with a drive shaft rotatable about a shaft axis and at least one set of electrical output leads, a support housing with a lower ground engaging base, an upper support plate with a central access opening, a bracket in the housing to mount the generator with the shaft axis extending generally vertically through the access opening and a platform on the housing to fixedly attach a standard lawn mower with a cutter blade rotatable about a blade axis onto the housing with the blade axis extending generally parallel to and generally aligned with the shaft axis. A universal shaft coupling carried by the drive shaft and extending through the access opening, which coupling has a lower section connected to the drive shaft for rotation about the shaft axis and an upper section with a nest to receive the cutter for rotation of the upper section about the blade axis.
A portable implement for providing a source of electrical energy, said implement having an electric generator with a drive shaft rotatable about a shaft axis and at least one set of electrical output leads, a support housing with a lower ground engaging base, an upper support plate with a central access opening, a bracket in said housing to mount said generator with said shaft axis extending generally vertically through said access opening, a platform on said housing to fixedly attach a standard gasoline driven lawn mower with a cutter blade rotatable about a blade axis onto said housing with said blade axis extending generally parallel to and generally aligned with said shaft axis and a universal shaft coupling carried by said drive shaft and extending through said access opening, said coupling having a lower section connected to said drive shaft for rotation about said shaft axis and an upper section with a nest to receive said cutter blade for rotation of said upper section about said blade axis.
A method of driving an electric generator by a drive shaft having an upstanding coupling with an upper section in the form of a circular disk provided with at least one diametrically extending blade receiving slot, said upper section spring biased in the direction of said shaft, said method comprising:
A portable generator for providing a source of electric energy, said generator having an upstanding drive shaft with a universal coupling having an upper section with upwardly facing cutter blade receiving nest and a lower section rotatably secured to said drive shaft whereby a gasoline driven lawn mower can be mounted on said coupling with said blade of said lawn mower drivingly engaging said nest.
