[D8954ADG], Letter from Dyer and Seely to Thomas Alva Edison, October 14th, 1889

Editor's Notes

"We enclose the tracing of your application No. 716 for multipolar machine. The Examiner has made the objection to this case that the arrangement shown in the drawing is inoperative for the reason "that though the device would generate a current in the position shown in Figure 1, when the device has rotated 90 [degrees] the current becomes nil. While at 180 [degrees] the coils are still in the same polarity as in the figure, while the brushes connect to the neutral points 90 [degrees} removed and hence of reverses polarity."####We would be glad if you would have some one study this out and see whether it is correct. If the drawing is wrong we should have it coorected and Mr. Kennelly or some one at the laboratory can probably show us how. If the drawing is right and the Examiner wrong, we would like to be furnished with such explanation as we can use to convince him of his error.####Kindly return the tracing with your reply.####Yours truly, Dyer & Seely####Mr Tate####The examiner is right and the correction is made in the accompanying sketch which should replace fig I. If desirable the M.SS. Might be sent us here to look over before being sent in again.####Yours Truly####A.E.K####[name mentions: Dyer & Seely, Thos Edison, U.S. Patent Office, A.E. Kennelly, A.O. Tate]
