Morton memorial; a history of the Stevens institute of technology, with biographies of the trustees, faculty, and alumni, and a record of the achievements of the Stevens family of engineers. pulse Wheel Co., New York, as assistantto the consulting engineer, at the same timeacting as consulting engineer for the Rush-more Dynamo Works. In September, 1897,he became chief engineer of the latter works,and with Mr. S. W. Rushmore brought out THE ALUMNI 457 the new multi-voltage dynamos. The arcdynamo suppHes any number of separate andparallel circuits of arc lamps, being the onlyone of the so-called multi-circuit arc ma-chines in which the circuits are not reallyin series. The multi-voltage dynamo doesaway with the troublesome and expensive booster, as feeder-circuits can be taken athigher potential from the same dynamo. In1898 he again entered the engineering de-partment of the American Impulse WheelCo., and during the Spanish-American Warhe had charge of the draughting-room of theRushyiore Dynamo Works, which were socrowded with government work that hishealth was considerably impaired. In 1899he designed for these works the largest dy-namo for D. C. arc lighting that had ever. R. T. KiNGSFORD been built, carrying two parallel and inde-pendently regulated series circuits of 150lights each. In 1900 his health was so poorthat he was compelled to give up work andspend a year in the Adirondacks. In April,1901, he went with the New York SafetySteam Power Co., New York, as chief en-gineer and engine-designer, but after a fewmonths he returned to the Adirondacks. For technical journals Mr. Kingsford, inconjunction with Mr. W. H. MacGregor(, 96), has written the following arti-cles: Test of an Otis Electric Elevatorwith Leonard Motor Control System/ Elec- trical Engineer, 1896; Method of Deter-mining the Indicated Horse-Power of an En-gine under Varying Load, Power, 1896,—both extracts from the graduating thesis ofMessrs. Kingsford and MacGregor. has also wr
