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.
