Robert Gayfer - Watertown NY
Assignee:
New York Air Brake Corporation - Watertown NY
International Classification:
A62C 1376
US Classification:
248 75, 248 92, 248499, 24300, 24301
Abstract:
A hose support system for a rail car having a support which includes a flat strap having first and second ends and a tongue connected to the first end of the strap and extending along the strap towards the second end of the strap. A connector at one end of the strap is positioned in a car aperture and a connector at the other end of the strap is positioned in a hose aperture. A resilient element connects the loop at one end of the strap to its connector. A clasp is adjustably positioned on the strap between the ends of the strap and adjusts the length of the strap between the ends. The tongue extends through the clasp. At least one of the connectors may include a loop and a throat extending substantially tangential to the loop. Alternatively, one or more of the connectors may include a spiral. A bearing ring separates the connector and the strap.

Michael Spadaccini - Dexter NY
Assignee:
New York Air Brake Corporation - Watertown NY
International Classification:
B60T 818
US Classification:
303 969, 303 221
Abstract:
An empty-load system including a first housing having brake cylinder, control valve, equalization volume reservoir and pilot ports. The first housing also has a ratio means for controlling the connection between ports and has a piston responsive to a pilot pressure to operate the ratio means. The system also includes a second housing having a brake cylinder port and a pilot port connected, respectively, to the brake cylinder port and the pilot port of the first housing. The second housing also has a sensor means, having a sensor piston, for sensing the load of a railcar and has a sensor valve for connecting the brake cylinder port to the pilot port for a first position of the sensor piston.
Unidirectional Stability Choke For A Brake Control Valve
View pageUS Patent:
6709070, Mar 23, 2004
Filed:
May 20, 2003
Appl. No.:
10/441219
Inventors:
Eric C. Wright - Evans Mill NY
Robert P. Gayfer - Watertown NY
Robert P. Gayfer - Watertown NY
Assignee:
New York Air Brake Corporation - Watertown NY
International Classification:
B60T 1706
US Classification:
303 81, 303 38, 303 86
Abstract:
A service portion of a rail pneumatic brake control valve which includes a piston responsive to pressure differential between brake pipe pressure at a brake pipe port and reservoir pressure at a reservoir port and a first valve controlled by the piston to determine pressure in a brake cylinder for a service application. A stability choke and check valve are connected in series between the brake pipe port and the reservoir port. The check valve permits flow from the brake pipe port to the reservoir port and prevents flow from the reservoir port to the brake pipe port independent of the piston.
One-Way Check Valve

Assignee:
Ellcon National, Inc. - Greenville SC
International Classification:
F16K 15/14
US Classification:
137846, 137843, 303 81
Abstract:
A railway car control valve comprises a brake pipe port, an auxiliary reservoir port, a main piston configured to compare air pressures at the brake pipe port and the auxiliary reservoir port, and a one-way check valve positioned intermediate the brake pipe port and the auxiliary reservoir port. The one way check valve comprises a body having a bore extending from its first end to its second end, an elongated insert configured to reduce the rate of air flow through the body, and a sleeve received on the insert's outer surface. The insert is received in the body bore. One of the insert and the sleeve is configured to move between a first position and a second position that either allows air to flow or prevents air from flowing, respectively.
Air Brake Control Valve With Combined Graduated And Direct Release
View pageUS Patent:
54294274, Jul 4, 1995
Filed:
Sep 23, 1994
Appl. No.:
8/311111
Inventors:
Robert Gayfer - Watertown NY
Assignee:
New York Air Brake - Watertown NY
International Classification:
B60T 1556
US Classification:
303 36
Abstract:
A control valve is mounted to a pipe bracket which also includes a manual release valve and an emergency vent valve. The control valve operates with a single reservoir to perform service and emergency brake applications. A pair of interrelated pistons responsive to brake cylinder pressure, brake pipe pressure and control volume pressure operate a supply valve, a quick service valve end exhaust valve to maintain a fixed ratio of brake cylinder pressure to brake pipe pressure reduction. Quick service volume is continuously vented and appropriate valving is provided to allow plural sequential quick service operations. Structures provided to operate the piston stack so as to initially allow graduated brake release and subsequent direct brake release over the brake releasing range. An accelerated emergency release mechanism is also provided. The supply reservoir is only charged during the direct release mode.
Emergency Vent Valve
View pageUS Patent:
55015131, Mar 26, 1996
Filed:
Nov 15, 1994
Appl. No.:
8/340856
Inventors:
Robert Gayfer - Watertown NY
Assignee:
New York Air Brake Corporation - Watertown NY
International Classification:
B60T 1518
US Classification:
303 73
Abstract:
An emergency vent valve including a piston responsive to the differential pressure between the brake pipe and a control volume to open a vent valve to vent the brake pipe to atmosphere and includes an exhaust valve responsive to the differential pressure between brake pipe and control volume to connect the control volume to atmosphere through a service check and when the vent valve is opened through a second blow-down choke of a lesser rate which limits the exhausting of the control chamber. A choke valve connected to the piston connects the blow-down choke in series with the service choke when the vent valve becomes fully open.

Zdzislaw Samulak - Watertown NY
Assignee:
Knorr Brake Holding Corp. - Westminster MD
International Classification:
B61H 1300
US Classification:
188 52
Abstract:
A brake system wherein the single actuator is freely mounted to a first brake beam so as to align its force application axis with the axis of a first force transmitting rod connected at its other end to a transfer lever on a second brake beam. A second force transmitting rod connects the transfer lever back to the first brake beam. The mounts for the actuator and the transfer lever are designed for use with brake beams of dual actuator brake systems.

New York Air Brake Corporation - Watertown NY
International Classification:
B60T 1552
US Classification:
303 36
Abstract:
A single sided control valve wherein the service portion is mounted to the front face of a pipe bracket adjacent to the right face and the emergency portion is mounted to the front face adjacent to the left face. The brake pipe, brake cylinder and at least one reservoir port are on the back face and the brake pipe port is adjacent to the left face behind the emergency portion. Mounting brackets each include a horizontal flange with apertures to receive the fasteners which mount the mounting brackets to the vehicle and the horizontal flange which extends from the pipe bracket substantially past the front face and the center of gravity of the control valve. A combined dirt collector and cut-off cock is connected to the brake pipe port adjacent to the left face of the pipe bracket and includes a handle to the left of the left face.
