Patent number: 10029713Abstract: A prolonged release system having a locking member pivotally mounted on a post within a hand brake and having an arm that contacts a clutch assembly to prevent the clutch assembly of the handbrake from engaging after it has been manually released. Rotation of the hand brake wheel causes a pawl on a ratchet gear to move into contact with a cam of the locking member so that the arm of the locking member moves out of contact with the clutch assembly. By maintaining the clutch assembly in a released position, the prolonged release system ensures that the brake chain drum is decoupled from the driveshaft of the hand brake and prevents the inadvertent application of the brakes. When a user turns the hand brake wheel, the locking member is disengaged from the clutch assembly and the hand brake can be set by a user.Type: GrantFiled: January 9, 2015Date of Patent: July 24, 2018Assignee: New York Air Brake, LLCInventors: Jeffrey F.

Patent number: 9963126Abstract: A computer controlled locomotive brake (CCB) configured for setting and releasing the automatic parking brakes of the railcars of a train. The CCB may initially recharge the brake pipe to a pressure slightly less than the parking brake unlatch pressure. The CCB may then continue charging to this level until the brake pipe flow, measured at the CCB on the controlling locomotive and the brake pipe pressure on the last car, as measured by an end of train device, indicate that the pressure in the braking system reservoirs are substantively equal to the brake pipe pressure. Once the reservoirs are substantively charged, the CCB may complete the brake release and recharge by recharging the brake pipe pressure to its final charge so that all parking brakes are released and the train has sufficient braking system recharge to safely control movement of the train.Type: GrantFiled: February 21, 2017Date of Patent: May 8, 2018Assignee: NEW YORK AIR BRAKE, LLCInventor: Eric C.
