[LB012347], Letter from Thomas Alva Edison to Henry Draper, May 18th, 1882

Editor's Notes

I received your letter of 14th inst and was sorry to hear that you do not get the results anticipated from the 55 volt armature owing to the imlpossibility of running your Gas Engine at the rate required##I will try and get an armature wound to gie the right volts at your regular speed but I think there must be some mistake about the revolutions as the machines are tested and give about nine candles at 2050 revolutions. Perhaps your belt slips or the commutator brushes are set too much forward in the direction of rotation. Please give it another trial and let me know the result.##Our Engineer (Mr Chas L. Clarke Edison Electric Light Co 65 Fifth Avenue) would go up to your house some evening and he would be able to see exactly what you want and calculate the size of wire to rewind your Bobbin within case you cannot get the present machine to work.##If you want Mr Clark please write him directly as I have advised him that it is possible you might do so.##When are you coming out to spend the day with me. I want you to come and to bring Mrs Draper with you. Nofity me by telegraph the night before and I will be here to receive you.##I shall certainly go up to spend a few hours with you when opportunity occurs but for some little time to come I do not expect to be in the City often
