Railway Locomotive Brake Controller

View page
US Patent:
6435624, Aug 20, 2002
Filed:
May 4, 2001
Appl. No.:
09/849738
Inventors:
Robert C. Kull - Olney MD
Robert D. Dimsa - Jefferson Hills PA
Assignee:
Westinghouse Air Brake Technologies Corporation - Wilmerding PA
International Classification:
B61L 2300
US Classification:
303 15, 303 7, 303 3, 303 16
Abstract:
An integrated locomotive braking and ECP braking control on a lead locomotive for implementing braking effort on all locomotives in a manner relative to braking effort applied on ECP freight cars. On the lead locomotive, a data interface can be established between an head-end-unit and a brake controller. The head-end-unit can electrically signal each ECP freight car to carry out braking commands. The integrated brake control can include a CPU, as part of either the brake controller or the head-end-unit, which can be programmed to provide braking effort on the lead locomotive relative to the braking effort applied on the ECP freight cars. The braking on the lead locomotive is implemented by the brake controller by controlling the independent brake relative to the braking effort commanded on the ECP freight cars. The independent brake on non-ECP trailing locomotives is connected to the lead locomotive independent brake via a standard independent brake pneumatic connection. As a result, the same braking effort applied on the lead locomotive via the independent brake is automatically implemented on the non-ECP trailing locomotives via the independent brake pneumatic connection such that all locomotives are braked relative to braking on the ECP freight cars.

Appl. No.:
11/607831
Inventors:
Edward W. Gaughan - Greensburg PA, US
Robert D. Dimsa - Jefferson Hills PA, US
Gary M. Sich - Irwin PA, US
Michael J. Veltri - Pittsburgh PA, US
Assignee:

Locomotive Equipment Carriage

View page
US Patent:
50257340, Jun 25, 1991
Filed:
May 3, 1990
Appl. No.:
7/518385
Inventors:
Michael E. Romansky - North Huntingdon PA
Robert D. Dimsa - Elizabeth PA
Howard R. Munday - Jacksonville FL
Assignee:
Westinghouse Air Brake Company - Wilmerding PA
International Classification:
B61C 1700
US Classification:
105 2605
Abstract:
An equipment carriage for locomotive air brake valve components including a box-like frame having a rear section separating parallel end sections. The frame is arranged to guidably receive, through an open front section, a group of one or more unitized valve assemblies stacked in vertical, side-by-side relationship, such that an end face adjacent the rear section engages a mating face of a respective header bar that is affixed to the frame at the rear section thereof to provide a pipe bracket to which the locomotive air lines are connected. Such an arrangement, in addition to providing optimum space utilization, permits removal of individual unitized assemblies from the frame without requiring removal of the frame itself or any of the other unitized assemblies, and without disturbing the air line connections.

Dual Valve Fitting For Enabling Quick Measurement Of Pressure

View page
US Patent:
60708549, Jun 6, 2000
Filed:
Nov 12, 1997
Appl. No.:
8/968271
Inventors:
Vincent F. Troiani - New Florence PA
Gregory L. Johnston - Tarentum PA
John B. Carroll - Irwin PA
Gary M. Sich - Irwin PA
Wei Li - Pittsburgh PA
Robert D. Dimsa - Elizabeth PA
Michael J. Veltri - Pittsburgh PA
Daniel G. Scott - Pittsburgh PA
Assignee:
Westinghouse Air Brake Company - Wilmerding PA
International Classification:
F16L 3728
US Classification:
2511496
Abstract:
A dual valve fitting enables quick measurement of pressure contained within a housing. The fitting includes a valve body, a valve retainer, first and second sealing rings and a biasing mechanism. The valve body defines a flow passage within which is situated the valve retainer. The valve body is designed at its protuberant end to mate with a female coupler of a quick connect device and at its threaded end to screw into a threaded bore of the housing. The valve retainer defines around itself first and second annular recesses each of which spaced apart from the other to match the spacing of outer and inner annular valve seats formed in the flow passage. Forming a first valve, the first sealing ring retains in the first annular recess so as to be seatable against the outer valve seat. Forming a second valve, the second sealing ring retains in the second annular recess so as to be seatable against the inner valve seat. The valve retainer is biased within the flow passage so that the first and second sealing rings seat against the outer and inner valve seats, respectively, thereby rendering the first and second valves normally closed.

US Patent:
55646573, Oct 15, 1996
Filed:
Nov 16, 1994
Appl. No.:
8/340525
Inventors:
Robert D. Dimsa - Elizabeth PA
Gary L. Bailey - Baden PA
Gregory S. Balukin - Pittsburgh PA
Vincent Ferri - Pittsburgh PA
Robert J. Jenets - North Huntingdon PA
Paul J. Kettle - Pittsburgh PA
Craig A. Miller - Pittsburgh PA
Daniel J. Wolf - Pittsburgh PA
Assignee:
Westinghouse Air Brake Company - Wilmerding PA
International Classification:
B61L 300
US Classification:
246187A
Abstract:
An electrically controlled railway locomotive throttle controller including a power source connected to a central processing unit disposed on such locomotive. An encoder device is disposed on such locomotive for providing at least one electrical signal to such central processing unit. This at least one electrical signal being at least one of a signal indicative of a throttle position, a signal indicative of dynamic braking and a signal indicative of a reverser. A digital control device is disposed on such locomotive and is connected to receive a signal from such central processing unit to provide a digital control signal that controls the voltage being applied to a trainline. An analog control device is also disposed on such locomotive and is connected to receive a signal from such central processing unit to provide an analog control signal that controls a dynamic brake reference voltage being applied to such trainline.

System For Automatically Delaying Application Of A Snow Brake For A Railway Vehicle

View page
US Patent:
43347118, Jun 15, 1982
Filed:
Oct 27, 1980
Appl. No.:
6/201094
Inventors:
Richard J. Mazur - Pittsburgh PA
Robert D. Dimsa - Irwin PA
John T. Pekarcik - Murrysville PA
Assignee:
American Standard Inc. - Wilmerding PA
International Classification:
B60T 712
US Classification:
303 16
Abstract:
A "snow brake" control system for a railway vehicle in which an electronic timing circuit is operative in response to the operator's brake valve device being moved to its brake release position to provide an output signal that acts through a relay switch to deenergize a magnet valve that normally interrupts communication of "snow brake" control pressure to the system relay valve in order to withhold "snow brake" operation for a predetermined period of time sufficient to allow the vehicle brake units to release the brakes and thereby effect operation of the brake unit slack adjuster mechanism. When the time period expires, the timing circuit output signal disappears and the magnet valve becomes energized to reestablish "snow brake" control pressure during the remainder of the brake release period to maintain a light brake application in effect.

Dual Valve Fitting For Enabling Quick Measurement Of Pressure

View page
US Patent:
6029700, Feb 29, 2000
Filed:
Aug 31, 1998
Appl. No.:
9/144676
Inventors:
Vincent F. Troiani - New Florence PA
Gregory L. Johnston - Tarentum PA
John B. Carroll - Irwin PA
Gary M. Sich - Irwin PA
Wei Li - Pittsburgh PA
Robert D. Dimsa - Elizabeth PA
Michael J. Veltri - Pittsburgh PA
Daniel G. Scott - Pittsburgh PA
Assignee:
Westinghouse Air Brake Company - Wilmerding PA
International Classification:
E03B 100
US Classification:
137613
Abstract:
A dual valve fitting enables pressure within a housing to be quickly measured. The fitting defines a passage between its threaded and protuberant ends. The threaded end screws into the housing. In an upper section of the passage, a first valve atop a valve stem features a poppet head that is seatable against an outer valve seat. A first biasing mechanism compels the head against the outer seat to keep the first valve normally closed. In a lower section of the passage, a second valve features a seat piece and a valve retainer. On its periphery, the seat piece carries an o-ring which sealingly secures the piece within the passage. The piece defines an inner bore between its ends and has an inner valve seat on its bottom. The top of the retainer is extendable through this inner bore to a point a dead space apart from a bottom of the stem. Around its bottom, the retainer carries an annular check valve.
