A t Liverpool I investigated the overhead elec-tric railway. The overhead structure, the motors,methods of collecting the current, etc., were ex-ceedingly well designed and constructed and gaveevidence of goof working The central stationapparatus and design was not, however, up to thestandard of work here in recent electric railways. The series parallel control is used, but no rheo-stat, the designer seeraiug to realize that it mightjust as well be left out, and the equivalent resist-ance secured in the windings of the motors them-selves, with less apparatus and no appreciable dif-ference in economy or control. THE HEILMANN LOCOMOTIVE. In France I examined what I considered themost important electrical engineering develop-. HEILMANN LOCOMOTIVE. pinging upon bucketsnear the peripherv of a disk,so that the machine is somewhat comparable tothe Pelton water wheel. 1 he steam, which is pre-ferably used at a high pressure, and exhaustinginto a vacuum, is expanded in a nozzle beforereaching the disk, and reaches the buckets of thethe disk fully expanded, and hence, moving at avery high velocity, which the inventor claims is3,000 feet per second for steam at 85 pounds persquare inch, exhausting into the air, and exhausting into vacuum. The nozzle makesa very slight angle with the plane of thedisk. The admission of steam is controlledbv a centrifugal throttling governor. The numberof revolutions of the disk per minute varies fromabout to 15,000 in sizes from 5 to 50-H. buckets are milled out of a solid disk of steel,just inside of the periphery, so as to leave a solidband on the circumference. The edges of thebuckets are quite sharp. The disk in a case of a50 h.
