This class relates to the distribution of fluid to brake motors, i.e., the utilization of fluid-pressure in the operation of brakes.
LINES WITH OTHER CLASSES
Systems for the distribution of pressure fluid to a plurality of motors other than brake motors are, for the most part in Class 60, Power Plants, subclasses 6, 97, 420, 484, and their respective indented subclasses, and Class 91, Motors: Expansible Chamber Type, subclasses 165+ and 508+.

60, Power Plants,
325+, for a pressure fluid source supply motive fluid to an
output motor of general utility, particularly subclasses 533+ a master-slave system. See the Search Class reference to Class 303 in subclass 533 of Class 60 for the line between these classes as to pulsators.
73, Measuring and Testing, 39, for devices for testing fluid brake systems and triple valves.
91, Motors: Expansible Chamber Type,
508+, for a system of plural expansible chamber motors of general utility and appropriate subclass for an expansible chamber motor, per se.
96, Gas Separation: Apparatus, for apparatus for gas separation, per se, which merely dry or separate foreign matter from gaseous brake fluids or which deaerate brake liquids.
116, Signals and Indicators,
55, for signal train-pipes supplied with fluid under pressure, the train brake-pipe, when used for signaling, being found in this subclass.
137, Fluid Handling, appropriate subclasses for fluid handling systems of more general application, and in particular see
203+, for devices for collecting and discharging condensate from a low point in the system, subclass 381 for shields to protect exposed valves, subclasses 545+ for devices for separating foreign matter from the brake fluid, and subclass 598 for distribution systems including a flow passage between a master cylinder and a brake cylinder and means to control the fluid flow, e.g., "hill holders", and see the Note to the definition of this subclass (598).
188, Brakes,
152+, and 154 for application of fluid-pressure operated brakes to motor-vehicles and to all road-vehicles.
246, Railway Switches and Signals,
167+, for operations on the air-distribution system from points on the railway-track. 252, Compositions, for fluids for hydraulic brakes or for other hydraulic devices.
293, Vehicle Fenders,
5, for the application of a fluid pressure operated brake to a motor vehicle combined with vehicle fender structure.
