Apparatus For Aligning Female Connector In Fixture For Use In Reconditioning Of Articulated Connector

US Patent:
7171734, Feb 6, 2007
Filed:
Mar 21, 2005
Appl. No.:
11/085296
Inventors:
Richard A. Brueckert - Chicago IL, US
William A. Guess - Omaha NE, US
Donald F. Kroesch - Minooka IL, US
Assignee:
TTX Company - Chicago IL
International Classification:
B23B 39/00, B23B 45/00, B23P 23/00, B23K 9/04, B23Q 17/00, B23K 31/00
US Classification:
29 26A, 29566, 29 565, 228119, 228 491, 219 7614, 408108
Abstract:
An apparatus for semi-automatically reconditioning an articulated connector while it is still mounted to the end structure of a rail car is disclosed. The apparatus is mountable to the connector and measures to find areas and amounts of wear on portions of the connector. The apparatus then applies weld metal to the worn portion of the connector. The excess weld metal is automatically machined away by the apparatus so that the connector falls within the required dimensions. The apparatus can again measure the weld area to ensure that the specified dimensions have been achieved. A method of aligning an articulated connector to a reconditioning fixture is also disclosed. The method includes securing the fixture to the connector and the use of gauges and tools to appropriately align the objects.

Yaw Damper For Railway Cars

US Patent:
5570640, Nov 5, 1996
Filed:
Dec 27, 1994
Appl. No.:
8/364353
Inventors:
Donald F. Kroesch - Minooka IL
Assignee:
Railway & Industrial Services, Inc. - Joliet IL
International Classification:
B61F 524
US Classification:
1051991
Abstract:
A yaw damper for railway cars comprises a pair of rotary hydraulic units connected to the laterally extending truck bolster of a railway truck assembly on opposite sides of its central pivot bearing member, a pair of connecting plates secured to the corresponding laterally extending car body bolster under a railway car in position on the truck assembly on opposite sides of the corresponding pivot bearing member of the car body bolster, the rotary hydraulic units on the truck bolster connected to respective ones of the connecting plates on the car body bolster by respective ones of a pair of longitudinally adjustable connecting rods. The connecting rods are connected at one end to the pivotable crank or stabilizing lever of respective ones of the hydraulic units and at the other end to connecting lugs of respective ones of the connecting plates. The hydraulic units are positioned against a forward or rearward side wall of the truck bolster in abutting relationship thereagainst to resist torque forces which would otherwise tend to rotate the housing of the rotary hydraulic unit when torque forces are applied to its pivotable crank or stabilizing lever. Such location forwardly or rearwardly of the truck bolster also enables use of a large hydraulic chamber able to provide greater torque and damping effect to control and minimize yaw of railway truck assemblies.
