Abstract: A contaminant mitigation device for use with a slack adjuster for a railway brake rigging to protect the critical operating area of the slack adjuster. The critical operating area of a slack adjuster includes the components that are configured to operate together to adjust the brake rigging. The slack adjuster includes at least a main housing portion, a cone nut housing portion enclosing the critical operating area of the slack adjuster, and an overtravel housing portion. The contaminant mitigation device includes a sealing system configured for cooperating with at least one of the main housing portion, cone nut housing portion, and overtravel housing portion to seal the critical operating area against entrance of fluid and/or contaminants therein and/or to at least reduce the exposure of this area to fluid and/or contaminants. The contaminant mitigation device can also include a drainage system associated therewith.

Abstract: A handbrake for a railroad car includes a handbrake body having one or more gear train components therein and a drive shaft operatively connected to the one or more gear train components. An intermediate pinion shaft is operatively connected to the drive shaft through one or more gears. A shaft alignment link is adapted for maintaining a relative spacing between the drive shaft and the intermediate pinion shaft during rotation of the drive shaft. A gear box housing is provided to enclose at least a portion of the drive shaft, the intermediate pinion shaft, and the shaft alignment link. The shaft alignment link is movable relative to the gear box housing due to any eccentric movement of the drive shaft to maintain the proper spacing between the drive shaft and the intermediate pinion shaft, thereby eliminating a possibility of gear binding. A method for aligning internal gear components within a handbrake and an alignment system for use with a railway vehicle handbrake is also provided.

Abstract: A drainage system for use with a slack adjuster for a railway brake rigging. The drainage system allows fluid and other contaminants to drain from the slack adjuster to prevent the fluid and contaminants from accumulating within the slack adjuster, contacting an operating area of the slack adjuster, and interfering with the operation of the slack adjuster. The slack adjuster includes a main housing portion, a cone nut housing portion enclosing a critical operating area of the slack adjuster, and an overtravel housing portion. The drainage system includes at least one aperture extending through a sidewall portion of the overtravel housing portion. The at least one aperture is configured to allow fluid and/or contaminants to drain there through to reduce exposure of the critical operating area to fluid and/or contaminants. A plug and/or patch can be provided to sealingly and/or removably engage the at least one aperture.
