Patent for an graduating valve that is used with air brake systems in railroad trains. The invention is meant to "produce a comparatively simple valve which is constructed in such a way that it is not likely to clog or get out of order, which is arranged so that successive regular reductions may be easily made in the pressure of air in the train service pipe, which is adapted to automatically act on the governor of the air pipe from pressure either above or below the main valve, which is constructed in such a way that if the train parts the pressure in the main reservoir will not be reduced, which generates excess pressure when the brake handle is in running position and acts through said excess pressure on the governor of the pump, which is not likely to leak, and which in general may be easily controlled and places the train brakes under the complete control of the engineer" (lines 11-29).
