Locomotive brake control apparatus suited for remote multiple unit operation

Abstract

Abstract BRAKE CONTROL APPARATUS FOR THE LEAD LOCOMOTIVE OF A MULTIPLE UNIT LOCOMOTIVE CONTROL SYSTEM WHEREIN THE BRAKE VALVE ON THE LEAD LOCOMOTIVE IS MANUALLY OPERABLE CONVENTIONALLY TO CONTROL APPLICATION AND RELEASE OF THE BRAKES ON THE FORWARD PORTION OF THE TRAIN FROM THE LEAD LOCOMOTIVE AND ALSO TO EFFECT CORRESPONDING CONTROL (VIA RADIO-TRANSMITTED SIGNALS INITIATED BY MANUAL OPERATION OF THE BRAKE VALVE ON THE LEAD LOCOMOTIVE) OF THE BRAKES ON THE REMAINING PORTION OF THE TRAIN FROM THE BRAKE VALVE ON A SLAVE LOCOMOTIVE REMOTELY LOCATED IN THE TRAIN. DIFFERENTIAL-PRESSURE-OPERATED MASTER CONTROLLER SWITCH DEVICES, SELECTIVELY OPERATED IN CORRESPONDENCE TO THE MANUAL OPERATION OF EITHER THE AUTOMATIC OR THE INDEPENDENT BRAKE VALVE ON THE LEAD LOCOMOTIVE, ESTABLISH SUITABLE CONTROL CIRCUITRY FOR RADIO TRANSMISSION OF APPROPRIATE BRAKE CONTROL SIGNALS FROM THE LEAD TO THE SLAVE LOCOMOTIVE SO AS TO CAUSE A VARIATION OF THE PRESSURE IN THE EQUALIZING RESERVOIR PRESSURE ON THE SLAVE LOCOMOTIVE, OR A VARIATION OF THE PRESSURE IN THE BRAKE CYLINDERS ON THE SLAVE LOCOMOTIVE, IN CORRESPONDENCE WITH THE VARIATION EFFECTED ON THE LEAD LOCOMOTIVE BY THE RESPECTIVE BRAKE VALVE THEREON, THEREBY INITIATING AN APPLICATION OR A RELEASE OF THE BRAKES ON THAT PORTION OF THE TRAIN COUPLED TO SLAVE LOCOMOTIVE CONCURRENTLY WITH THAT INITIATED ON THAT PORTION OF THE TRAIN COUPLED TO THE LEAD LOCOMOTIVE, OR TO CAUSE INDEPENDENT APPLICATION AND RELEASE OF THE BRAKES ON THE SLAVE LOCOMOTIVE SUBSTANTIALLY SIMULTANEOUSLY WITH THAT ON THE LEAD LOCOMOTIVE.
