The desirability ofcleaning motors, and electrical apparatus generally, by forcingair through the motor casings has long been recognized in shop apparatus. Figs. 1 and 2 illustrate the car now being used forthe tests at Camden. It will be noticed that in this equipmentthe funnel or hood is located on the top of the car, but in othertests the funnel has been placed at other points, above thecenter of the car, for instance, and in some it has been set in thedashboard (Fig. 3) or secured just below the platform of themotormans cab. This is a detail which may be determined bylocal conditions. Fig. 4 shows the truck of the Camden carupon which one of the exhausts is secured, and Fig. 5 is a planof the piping under the car showing the connections betweenthe motor casings and the pipe leading to the air collector. It. FIG. 1.—CAMDEN CAR EQUIPPED WITH RAILWAY MOTORVENTILATOR practice, and the plan followed in these investigations reallyutilizes the same principles, only in this case it is not necessaryto depend upon mechanical means for securing sufficient pres-sure to force the air through the motor casings. Natural draftis used, the air being admitted through a funnel or hood con-veniently located on the outside of the car, either in front orabove the roof, as may be desired. A pipe leads from this hood FIG. 4.—EXHAUST ON TRUCK will be noticed that both of the motor casings are connectedwith the air supply, the main pipe going directly to the firstmotor, and a branch leading to the casing on the rear axle. Inthe top of each motor case is a vent, from which a pipe is ex-tended to the outside line of the car body. The funnel-shapedhood at the end of this pipe, which serves as an exhaust, isfixed on the car truck in such a position that it will carry offthe hot air from
