Abstract

"Thank you for information received, in yours of April 18th ## What would you say to a plan for winding an armature thusly. ## Instead of straight & regular; And one set of blocks; to split each section, just a set of blocks on each end of armature with brushes. and take one half the engine E. M. F. from each set of brushes. ## I.E. one of your regular machines, will give 'max' voltage of 125. It is proposed to half the section & put on an extra commutator, and brushes-- and take 62.5 Volts from each set of brushes. ## Of Course, the machines working in such a manner shall be separately excited. ## Do you think it would be profitable to experiment any in this direction. ## I think it possible to induce Gen'l Eckert to try such a scheme, on a small scale. Or perhaps you have already done so, and find objections. ## I do not recall any record fo such plan. ## The saving would be in floor space, belting etc and would be available only fo rthe W. U.: specially because of peculiar work required. ## I would be grateful for a word or minutess talk about this, and shall await your pleasure."
