Patent number: 6619138Abstract: A flow adapter for measuring the rate at which air flows into the brake pipe. The adapter includes a housing, a flow valve and a transducer. The primary passage of the housing contains a primary orifice and a secondary passage contains a secondary orifice. The flow valve is disposed within a supplemental passage. When the rate of air flowing from the input passage into the input chamber is less than or equal to a predetermined amount, the flow valve closes the supplemental passage. When the flow rate into the input chamber is greater than the predetermined amount, the flow valve opens the passage to an extent determined by the magnitude of the flow rate. This allows air to flow through the supplemental passage, in addition to that flowing through the primary passage. The transducer generates a signal proportional to the difference in pressure between input and output chambers.Type: GrantFiled: July 7, 1999Date of Patent: September 16, 2003Assignee: Westinghouse Air Brake Technologies CorporationInventors: Paul J.

Patent number: 6249722Abstract: An improved method is used to control the pressure in the brake pipe of a train. The train is equipped with an automatic brake handle, an equalizing reservoir, a brake pipe control device and a computer for controlling the control device according to position of the handle. The method involves the steps of: moving the handle to a point along its range of motion; and storing in the computer as a setpoint the value desired for the pressure in the brake pipe. At whichever point the handle occupies along its range of motion, there is a particular pressure setpoint corresponding thereto. The method next includes the steps of: directing the computer to command the control device to modify the actual pressure in the equalizing reservoir to the setpoint thereby also causing the actual brake pipe pressure to approach the setpoint.Type: GrantFiled: March 11, 1998Date of Patent: June 19, 2001Assignee: Westinghouse Air Brake CompanyInventors: Gregory S.

Patent number: 6085608Abstract: A handle assembly, of the type used in railway locomotives, which includes a base plate, a cam mount attached to the base plate, a cam disk and a shaft assembly interconnecting the mount and disk to allow rotation of the disk. The improvement includes a yoke, a bail bar, first and second bearing members anchored to the plate and first and second switches attached to the plate. Pivotally connected to the disk and accommodating a handle, the yoke rotates along with the disk as the handle is moved along its range of motion and tilts as the handle is moved perpendicularly thereto. The bail bar is rotatable between the first and second bearing members. A first mechanism imparts a rotational force to the bail bar so that its middle section presses against an upper portion of the yoke. A stop limits rotation of the bail bar to a point at which the yoke and handle attain an untilted state.Type: GrantFiled: March 19, 1998Date of Patent: July 11, 2000Assignee: Westinghouse Air Brake Co.Inventors: Ralph Santoro, Jr., Paul J.
