A NEW BRAKE TESTING MACHINE

The Inertia Machine Mark V, which can be used for recording deceleration, torque, and friction surface temperature in one operation, is described and illustrated. The machine is capable of dealing with any of the shoe or disc brakes used on railcars, and it should eventually deal in a similar manner with brake blocks for actual wheel rim braking. The design, generally, resembles a fully floating back axle, the motor taking the place of the differential gear, and the flywheels replacing the road wheels. The brake units are mounted on a shaft coupled to a torque recording gear carried in headstocks, which may be retracted axially to remove the brake units from their drums. The machine is a double-ended one to allow two brakes to be tested simultaneously, alternately, or individually. The flywheel specifications, torque recording system, and pyrometer are briefly described.
