Westinghouse resistances have been modified to givemore room for ventilation, and make it possible to take thespools apart easily. One of these resistances is shown inFig. 15. During rush hours, at present writing, 860 motor carsare run, and on Sunday 1200 motor cars. About twentymen are employed in the armature repair FIG. 12.—TESTING FRAME SCALES AND MOVABLE CONTROLLER WITH LEADS AND PLUGS M. H. Logan, electrician of this department, has madeout a table of data on motor windings used by the com-pany for convenience and quick reference, which, throughhis courtesy, is here given, as it may prove of use to othersin similar work. Mr. Logan is also preparing for referencepurposes a set of prints showing the core commutator andthree or four coils of each type of armature. With theseany armature winder can learn the winding of an armaturehe is not familiar with in a very short time, and with littleother instruction. MASTER MECHANICS RECORDS With the consolidation of so many car shops and housesunder one management, Lee Massengale, master me-chanic, appreciated more fully than do many the impor- used. The foremen turn these in to the master mechanic,and by 10 oclock the next morning the master mechanichas a good idea of what was done on the road the previousday. The workmans r
