This cranetakes motors and armatures out of trucks and deposits them on the floor, where the armatures can be rolled towithin reach of the revolving cranes at the machine shop equipment was originally designed to handle armatures and motors. These are now operatedas four-motor equipments. In order to increase the motorcapacity that could be put on a single truck with insidehung motors, the G. motor was designed, which has. FIG. 2.—CRANE FOR HOISTING MOTORS a motor casing which overhangs the bearings. The motorcasing is not divided into halves, as had been the practicein electric railway motor designing in America previous tothe time that this motor was brought out. It has, instead,an opening in the end of the case, through which the arma-ture is taken out. To remove an armature in this way, ofcourse, required somewhat radical changes from any pre-vious practice in removing armatures from motors. For
