Show CHARLES FRANCIS BRUSH A great inventory career and anc cm ST chronicle charles francis brush WM born in a farmhouse near cleveland march 1819 just thirty one years ao hi father 18 a wealthy farmer and land owner ft man of fine personal appear ance and alio most congenial man ners aho vho is familiarly known to old Clev elanders us colonel brush the aon entered the high school in this city in 1863 and is remembered a a very proficient student and a general favorite he was graduated in a four years course in two and a half years and then went to gan university where he graduated as a raining engineer in 1869 on year ahead of the class he entered with returning to cleveland he established u laboratory and conducted the business of an analytical chemist for about thre years becoming noted for the accuracy of his work and the skill displayed in his manipulations in a lawsuit in which he was pitted against professors bilu man chandler and other well known chemists he waa quite successful in overturning their evidence shortly after this ho went into the business in which he remained four years in 1875 his attention was called to the subject of electric lighting by the experiments teiei triei in paris and london with the gramme and siemens machines he had given the general subject great deal thought in previous years some of his electric researches going back to his early school days in 1862 at the age of 13 while at school he made his first experiments avith marnets and batteries paying an old blacksmith five cents to bend up an iron rod for an electro magnet while at the high school in 1864 he became much interested te in the subject of microscopes and tole cocea making ft number of them for himself and companions grinding abo lenses and making every part of the instrument in the game year he devised A plan fr turning gas on to the tret lump lighting it and then turning it oft again by electricity he made a working mo delbut finally concluded that such a system involved certain difficulties that deprived it of any practical economic value nd he therefore carried hl investigations no further all other systems since have failed for like reasons youn brush alo constructed number of induction coila and sold them to his schoolmates for shocking purpose throughout his school days he was constantly working at one chinor of thi general cht racier some of the in lighting which he has since developed were the outgrowth of his eions and experiments white he was at school and college A peculiarity of hia methods in work early developed itself he uever made any merely empirical experiments and in fact he made very few of any kind when his at tension wa called ta a particular subject by the necessity for macje im proved methods and machines bis habit was not to loo c op text hooks and reference volumes to fiad what others had done and endeavor to improve on their work but if possible to strike out a road and avoid the ruts he iho rare faculty of placing before his minds eye in the clearest any of his new conceptions and there examining them from all files most thoroughly without the slightest aid from drawings or models after thus selecting the mot approved method and after it to the keenest mental scrutiny ecru tiny the next step is usually the making not of a sketch or hasty drawing but of the complete working drawing with full details to scale ready for the patternmaker pattern maker the whole tub been so thoroughly worked out in his mind that in nine out of ten the very first machine or piece of apparatus made from his drawing is found to be perfect in every minute detail and ready for practical use it was in 1875 aa above stated that his attention was specially called to the state of the art of electric lighting and in a conversation with george W Sl ockley the president of the telegraph supply company of cleveland the question came up as to whether there was not a field and likely to be a demand for a dynamo electrio machine entirely different dif Terent froni the gramma and siemens the then best known machines and superior to them As a result of this conversation an arrangement ran gement was made that sir brush waa to have such facilities as be needed in the factory of the company and if he produced the desired ma cune the company would undertake its and introduce tion mr brush made no promises whatever to mr yi ockley ivea though be was an old school friend and very little WM heard from and nothing seen of the machine which mr brush was quietly constructing at home n bis laboratory in less than two months from the time of the conversation above al eluded to mf brush quietly came down to the factory one morning bringing the with him in a buggy it was set up in the en of the shop and connected by a belt with the main shaft and by wires to an old style clockwork electric lamp with carbon points in tho usual manner the power was applied revoked ta current of electricity was generated and the lamp alye forth its brilliant light U was a gratifying aud res roar kable success not a pra roie had been niage no ono in he fao lory not fiven mr stockley had seen tho anichino until that moment and
