Abstract
Abstract A method of generating electricity by a wind blown turbine comprising mounting a generator aramture rigidly on a shaft; rotatably mounting a housing, a field coil and a wind turbine with respect to the shaft; electrically connecting the field coil through brushes and a brush plate; and mounting the shaft against rotation so that when air currents rotate the wind turbine, the housing, the field coil, and the brush plate will rotate whereby electrical current generated in the field coil will be transmitted to output lines. An apparatus for generating electricity comprising an armature rigidly mounted on a shaft and a wind turbine rotatably mounted on the shaft. A housing with a field coil is mounted within the wind turbine and surrounds the armature. A brush plate with brushes electrically connects the field coil. Air currents rotate the wind turbine to cause the field coil to rotate about the armature. Electrical current generated in the field coil is transmitted through the brushes to output leads.

Claim 1
Independent Claim
252 words
The method of generating electricity by a wind blown turbine, comprising, taking an electrical generator having a housing with an elongated drive shaft means in said housing and extending from said housing in at least one direction, an armature in said housing secured to said shaft, a field coil in said housing in spaced relation to said armature, and a bearing means between said shaft and said housing to permit relative rotational movement therebetween, rotatably mounting a brush plate with brushes thereon on said shaft outside said housing, rigidly mounting a pickup plate with electrical contacts on said shaft adjacent said brush plate so that said brushes are in slidable contact with said electrical contacts, taking a wind turbine having a rotational axis and aligning said axis with said shaft, rigidly linking said wind turbine, said housing, and said brush plate together so that they can rotate together in unison about the same axis when air currents engage said wind turbine and cause it to rotate, holding said shaft against rotation, electrically connecting said field coil with said brushes, electrically connecting said electrical contacts to electrical output lines, and rotatably mounting said wind turbine on a support means, whereby air currents rotating said wind turbine will cause said housing and said field coil to rotate about said armature to generate an electrical current in said field coil, and whereupon said electrical current will be transmitted to said electrical output lines through said brushes, and through said electrical contacts on said pickup plate.
