To 'all whom it may concern:

Be it known that I, THOMAS K. S'rmrm, a citizen of the United States, residing at Rolette, in the county'of Rolette, State of North Dakota, have invented certain new and useful Improvements in Electrical Generators; and Ida hereby declare the following to bee full, clear, and exact description of the invention, such as will enable others skilledin the art to which-it appertains to make and use the same.

This invention relates to electrical'geneiators and particularly to one which may be easily and conveniently attached to. the usual windmill.

The object of the invention is to so arrange mechanism ofthis character upon-the usual windmill, that the wind wheel proper and its head may rotate in the usual manner and the current generated may-be distributed to any suitable point and for any use.

In the drawings :--F igure 1 is a side elevation of the device mounted upon theusuel windmill. Fig. 2 is a transverse sectional view taken on line 2-2 of Fig. 1. Fig. 3 is a vertical sectional view of the circular contact supporting member. Fig. i is a detailed perspective view of the arm for supporting contact brushes.

Referring to the drawings, the numeral 1 designates the wind wheel of anywell known form, said wheel being mounted upon the revolving head 2, the Wheel and head both being mounted upon the support ing legs 3. which are braced in the usual manner. Secured to the head 2 is a shelf 4 and on which is supported and secured a generator said gcncr'zitor having its arniaturc shaft 5 provided with a worm and supported at its extreme inner end by a brackct- 7.. said bracket beingsuitably se- 'curcd to 4110 shelf. Adapted to mesh with the worm i is a worm gear S'lhrough which a shaft S) pass-cs, said worm gear being rigidly secured to the shaft. The opposite ends of the shaft 9 are 'j ournaled in brackets 10, said brackets being secured to the shelf l. lligidly secured to the shaft 9 and between the brackcls it) is a gear wheel l1 and over which is passed a sprocket clrain 12, said sprocket chain leading to and passing around a sprocket wheel 13 l usual \vind whccl shaft.

The outer end of the armature shaft 5 is provided with the usual commutator l4,

and arranged in contacting relation there- .tions of weather.

member 22 are formed annular groovesj l (eyed to the with are positive and negative brushes 15 andlfi, and from which wires 17 and 18 lead to brushesv 19 and 20, said brushes be ing suitably secured and insulated from'ti downwardly extending arm '21, said arm being secured to the under side of the shelf 4-.

. Encirclmg the legs 3 is a. fiber member 22, said member being'formed in two sections to facilitate the application of the same to the legs, said sections being secured to the legs 3 by brackets 23. These sections are formed/from what, is commonly known in the trade as red fiber, such material being I especially adapted to Withstand allc0ndi- In the outer face of the and in which are placed copper rings and with which the brushes 19 and 20contach and travel over as the head 2-revolves carrying with itthe shelf 4 and the mecha-- nism thereon. Upon the lower face of the member 22 are secured binding post's'26 and 27 and to which the ends of wires 2.8'and 29 are connected, said Wires leading to storage batteries or directly connected to a. machine to be operated. Connected. to each 'ring and passing through suitable openings formed in the member 22 arewires Which have their lower ends connected to the. binding posts 26 and 27, sothat the circuit, is completed through the rings and binding posts as the brushes 19 and 20' travel around the rings 25. v

To protect the contact rings from the Weather and prevent short circuiting due to moisture i provide a casing 30, said casing being formed in twosections and having upper and lower curved flanges 31 and 32, said flanges contacting with the upper and lower faces of the fiber member 22, respectively. 0110 section of the casing 30 is formed'wi-th an oil set 33, and by which the same is socured in any suitable manner to the lower end, of the arni'21. I The operation hf the device is'as follows: As the Wind wheehrot-ates, the worm-gearing will be actuated by the sprocket 12, so that the armature shaft 5 is rotated, then.- by generating the current, which passes through the positive and negative wires to the brushes 19 and 20, and from thence through the rings 25 through wires 28 and 29 to its point of use.
