Patent number: 10272894Abstract: A control valve includes a diaphragm with a flow path with a predetermined cross-section from a brake pipe to a first side of the diaphragm and another flow path having another predetermined cross-section from a second side of the diaphragm to atmosphere. A dump valve prevents flow from the brake pipe to atmosphere. A method for operating a control valve includes supplying brake pipe air to a first side of a diaphragm through a flow path having a predetermined cross-section and permitting or preventing reference air flow to atmosphere through another flow path having another predetermined cross-section. The method further includes supplying reference air to a dump valve that prevents brake pipe air flow to atmosphere.Type: GrantFiled: March 7, 2017Date of Patent: April 30, 2019Assignee: AMSTED RAIL COMPANY, INC.Inventor: Daniel Brushwood

Patent number: 10112594Abstract: Valves for maintaining brake cylinder pressure in freight car brake equipment are provided. A valve includes a first diaphragm defining a first side and a second side, and a second diaphragm defining a first side and a second side. The valve further includes a first port for receiving pressure from one of an emergency reservoir or a control volume, the first port in fluid communication with the first side of the first diaphragm; a second port for receiving pressure from a brake pipe, the second port in fluid communication with the second side of the first diaphragm; and a third port for receiving pressure from a brake cylinder, the third port in fluid communication with the second side of the second diaphragm.Type: GrantFiled: September 23, 2015Date of Patent: October 30, 2018Assignee: Amsted Rail Company, Inc.Inventors: Daniel Goujon, Patrick Adams, Roberto Correndo, Mickael Marechal, Daniel Brushwood

Patent number: 9915358Abstract: A valve includes a valve body and a handle operably connected to the valve body. The handle has a shut position that prevents fluid flow through the valve body and an open position that permits fluid flow through the valve body. A shut detent is configured to engage with the handle in the shut position, and the valve further includes structure for biasing the handle toward the open position.Type: GrantFiled: February 6, 2013Date of Patent: March 13, 2018Assignee: AMSTED RAIL COMPANY, INC.Inventor: Daniel Brushwood

Patent number: 6688559Abstract: A modular sensor apparatus for detecting the location of a movable track point includes a primary sensor and a secondary sensor disposed on a sensor mount that is movable with respect to a frame that is mounted on a switch machine. The secondary sensor is offset from the primary sensor in order to permit the secondary sensor to detect the need for imminent readjustment of the track point prior to the time at which the track point becomes maladjusted and in need of immediate readjustment. The sensor mount is threadably adjustable with respect to the frame, whereby once the primary sensor has detected the position of the movable track point when it is disposed against a fixed stock rail, the sensor mount can be moved a fixed threshold distance by rotating a thumbwheel a fixed number of turns.Type: GrantFiled: December 30, 2002Date of Patent: February 10, 2004Assignee: Union Switch & Signal, Inc.Inventor: Daniel Brushwood

Patent number: 6471163Abstract: An improved ergonomic hand throw arm for use in conjunction with a railroad switch machine includes an elongated shank and a head disposed thereon. The shank includes a longitudinal axis, and the head includes a first opening and a second opening that are each offset in opposite directions from the longitudinal axis. The head includes an elongated rib that is disposed between the first and second openings and that extends in a direction that is substantially parallel with and may be in register with the longitudinal axis of the shank. The first and second openings are each elongated and are sized to permit the entry of a gloved hand therein yet resist the entry of a toe of a conventional steel toed boot or shoe that is manufactured according to Standard Z41 of the American National Standards Institute.Type: GrantFiled: October 9, 2001Date of Patent: October 29, 2002Assignee: Union Switch & Signal, Inc.Inventor: Daniel Brushwood
