Abstract
Abstract A device for collecting a charge of static electricity by rotating a disc or wheel carrying a plurality of individual conductors in proximity to a pair of stationary conductors. Four stationary brushes are arranged in two pairs to wipe the charge from the individual conductors which is initially induced by the natural imbalance in static charge between the stationary and moving conductors. The charges from each pair of brushes are returned to the stationary conductors and stored on an appropriate capacitor.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
173 words
An electrostatic generator comprising, in combination: a. a first pair of conducting brushes electrically connected to one another; b. A second pair of conducting brushes electrically insulated from one another and from the brushes of said first pair; c. first and second electrical conductors mounted on a common first support and electrically insulated from one another, d. means electrically connecting one of the brushes of said second pair to said first conductor, and the other to said second conductor; e. a plurality of individually insulated additional conductors mounted on a common second support; f. means for causing movement of said additional conductors relative to said brushes, in successive winding contact with brushes of opposite ones of said pairs, and to said first and second conductors, in physical proximity thereto close enough to allow significant mutual influence of the respective electrical charges of said additional conductors on said first and second conductors, but electrically insulated therefrom; and g. means forming an electrical capacitor with the plates connected respectively to said first and second conductors.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
22 words
The invention according to claim 1 wherein said additional conductors are arranged in a circular configuration and said relative movement is rotary.
Claim 4
Dependent Claim
30 words
The invention according to claim 2 wherein said additional conductors are arranged on an insulating disc which is rotated while said brushes and said first and second conductors remain stationary.
Claim 5
Dependent Claim
32 words
The invention according to claim 3 wherein said brushes and said first and second conductors are carried on an electrically insulating backing plate which also supports motive means for rotating said disc.
Claim 6
Dependent Claim
38 words
The invention according to claim 4 wherein said disc and said backing plate are arranged in closely adjacent, parallel planes and said first and second conductors are on the opposite side of said backing plate from said disc.
Claim 7
Dependent Claim

Claim 9
Dependent Claim
46 words
The invention according to claim 6 wherein said additional conductors are carried on the side of said disc which faces said backing plate and said brushes are spaced 180* from the other brush of the same pair and 90* from the brushes of the opposite pair.
Claim 10
Dependent Claim
71 words
The invention according to claim 8 wherein said first conductor includes two enlarged portions, electrically connected and spaced 90* from one another on the path of a circle in a plane adjacent the plane of rotation of said additional conductors, and said second conductor includes two enlarged portions, electrically connected and spaced 90* from one another and from the two portions of said first conductor on the path of said circle.
Claim 11
Dependent Claim
23 words
The invention according to claim 9 wherein said backing plate is supported on a base whereon the plates of said capacitor are arranged.
