- Editor's Notes
- [FOR WO LIBRARY?] Upon receipt of your order of the 11th inst. Requesting us to furnish you with a full set of patents on Dynamos and Motors, Electric Brakes, and transformers, we wrote to the Patent Office for an estimate of the cost of six copies of all patents issued relating to those classes. We enclose the estimate herewith, which shows that under the class of Generation of Electricity, the following number of patents were issued: Magneto-electric 768; Induction coils, 112; and Systems of Distribution, 136, making a total of 1016; under the class of Electricity-Motive Power, the following were issed: Motors, 337; Car Brakes, 74; Transmission of Power, 82; and Locomotion, 408, making a total of 846. The total number of patents issued under these two classes is 1862, which we can obtain for you at the rate of ten cents per copy. If you do not care to take all the sub-classes mentioned in the estimate, indicate those which you do not want, and send us a check for the balance at the above rate.####You will notice that the estimate mentions patents issued in eleectrical signalling, this however has nothing to do with the copies you want. These were ordered in connection with another matter. Please return the estimate to us
