Anotlier peculiarity of tliis machine is the large number of poles feature, which in ordinary designs would be bad practice, is avaluable one of this pecviliar style of design, enabling the builders togreatly shorten their armature conductors, and to use on alltheir armatures what may be described as the cylindro-hex-agonal style of drum winding. In this winding, all parts of every con-ductor of any particular layer on the armature lie in the same cylin-drical surface, and the windings do not bend down over the end of thearmature core at any point, and the conductors being placed throughthe core and below the surface, no binding wire is necessary. Fig. ID is a view of complete brush holder arrangement. The brushholders project outward, and leave the entire outer end of the commu-tator free and accessible. The whol
