Patent number: 11745715Abstract: A brake cylinder maintaining system that combines a brake cylinder maintaining check valve and a quick service limiting valve into a single unit to have lower hysteresis, and thus more precise BCM regulation pressure and a smaller pressure offset. The check valve and quick service valve are coupled to provide a single system having multiple valve seats for selective communication between quick service pressure and brake cylinder pressure on one hand, and between a brake cylinder maintaining pressure and brake cylinder pressure on the other hand.Type: GrantFiled: January 25, 2021Date of Patent: September 5, 2023Assignee: NEW YORK AIR BRAKE, LLCInventors: Derick Call, Howard E. Huber, Jr., Brian Graves

Patent number: 9623855Abstract: A brake system for a rail vehicle including a brake cylinder having a housing, a port on the housing for receiving fluid pressure signals, a pressure piston carried inside the housing, and a shaft connected to the pressure piston. The pressure piston and the shaft form an actuator to apply and release the brakes of the rail vehicle. A parking brake locking mechanism is connected to the actuator and is responsive to fluid signals from a fluid charged brake pipe to lock and unlock the parking brake locking mechanism. Further included is a manual release device configured to unlock the parking brake locking mechanism from the locked position.Type: GrantFiled: May 23, 2008Date of Patent: April 18, 2017Assignee: NEW YORK AIR BRAKE LLCInventors: Howard E. Huber, Simon Czypionka

Patent number: 9327739Abstract: A slack adjuster having a single, unitary housing that changes in length to compensate for brake pad wear in a rail car braking system. A threaded tension rod extends a variable length from the housing depending on rotation of the tension rod relative to the housing. A clutch assembly enclosed within a rod guide controls rotation of the tension rod and an overtravel assembly positioned in the single housing controls whether the clutch assembly will allow or prevent rotation of the threaded rod. A control rod and actuating tube transmit the controlling forces to the overtravel assembly so that the tension rod will be retained in a new length when the slack adjuster needs to take up slack in the braking system.Type: GrantFiled: September 17, 2014Date of Patent: May 3, 2016Assignee: New York Air Brake, LLCInventors: Howard E. Huber, Jr., Ann Gibson

Patent number: 9272718Abstract: A slack adjuster that is protected against environmental contaminants via a series of holes positioned circumferentially around each end and covered by a sleeve having a slot is aligned with one of the series of holes while covering the remaining holes. The sleeve protects against infiltration of contaminants at the ends of the slack adjuster and allows any contaminants that do infiltrate the slack adjuster to be expelled through the aligned hole and slot. The central portion of the slack adjuster may also be protected by including a series of circumferential holes that are selectively covered by a sleeve having a drain positioned to align with the lowest holes while covering the remaining holes.Type: GrantFiled: August 19, 2014Date of Patent: March 1, 2016Assignee: New York Air Brake, LLCInventors: Howard E. Huber, Jr., Eric C. Wright, Jeffrey Sauter

Patent number: 9180853Abstract: In a rail vehicle hand brake having a release activated by a pneumatic cylinder, the present control system includes a manual valve having an output connected to a source of pressure at an input when manually activated. A volume is to be charged by the source of pressure. A choke connects the volume to exhaust. The volume and the choke prolong the time the source of pressure is connected to the pneumatic cylinder after the manual valve is activated.Type: GrantFiled: June 11, 2014Date of Patent: November 10, 2015Assignee: New York Air Brake LLCInventors: Derick Call, Steven R. Newton, Lawrence E. Vaughn, Jeffrey F. Sauter, Howard E. Huber, Jr.

Patent number: 8991568Abstract: A brake system includes a brake cylinder having a piston rod and a brake lever connecting the piston rod to a brake beam and a slack adjuster. An actuating lever is connected to the brake beam and the brake cylinder. A trigger of the slack adjuster is connected to the actuating lever. The actuating lever is pivotally and rotationally connected to the brake beam and swivelably connected to the brake cylinder. Also, a piston stoke indictor including an indicia positioned on a support structure of a brake cylinder to be adjacent the end of a portion of a brake piston at its extended position.Type: GrantFiled: March 8, 2010Date of Patent: March 31, 2015Assignee: New York Air Brake CorporationInventors: Derick Call, Howard E. Huber, Jr., Steven R. Newton, Jeffrey F. Sauter, Eric Wright

Patent number: 8919892Abstract: The dual vent valve includes a housing having brake pipe, emergency input and exhaust ports, and first and second valves. The emergency output port is fluidly connected to the emergency input port. The first valve selectively connects the brake pipe port to the exhaust port by opening the first valve in response to an emergency signal on the brake pipe port. The second valve selectively connects the brake pipe port to the exhaust port by opening the second valve in response to an emergency signal on the emergency input port.Type: GrantFiled: November 8, 2007Date of Patent: December 30, 2014Assignee: New York Air Brake CorporationInventors: John M.
