Patent number: 10059314Abstract: A bail compensating joint may include a threaded push rod, a ratchet in threaded connection with the push rod for rotational motion thereon, and a helical joint including a first bearing and a second bearing mounted on the ratchet for facilitating rotation of the ratchet. The second bearing is supported by an annular composite race member formed by a metal annular inner race member joined with a resiliently deformable annular outer member. In another embodiment of the bail compensating joint, a pair of spherical joints is disposed on opposite sides of the ratchet, the spherical joints supporting the respective first and second bearings.Type: GrantFiled: October 1, 2014Date of Patent: August 28, 2018Assignee: Wabtec Holding Corp.Inventors: Michael Koziol, Richard Wayne Plegge, Peter Paul Gregar

Patent number: 10059352Abstract: A corrective device for correcting uneven brake shoe wear on a brake mechanism for a railway vehicle, wherein the railway vehicle includes a brake beam having a tension beam coupled to a compression beam, a brake head with brake shoes provided at each end of the brake beams, and a slack adjuster. The corrective device is configured to cooperate with at least one of the compression beam and the slack adjuster to minimize or prevent the compression beam and the tension beam from rotating relative to the wheels and side frames of the railway vehicle. A braking system including the corrective device and a method for correcting uneven brake shoe wear on a brake mechanism for a railway vehicle is also provided.Type: GrantFiled: June 10, 2014Date of Patent: August 28, 2018Assignee: Wabtec Holding Corp.Inventor: Michael Koziol

Patent number: 9856933Abstract: A debris eradicating brake head for use in a side frame mounted braking system in a railway vehicle. The brake head being mounted on an end of a brake beam and including a brake shoe carrier associated with the brake head, a brake shoe secured to a face portion of the brake shoe carrier, and a brake head extension extending from a side portion of the brake shoe carrier for associating the brake head within a unit guide in a side frame of the railway vehicle. The brake head extension including at least one of a first and a second tapered surface configured for breaking up and pushing debris out of the unit guide in the side frame. Eradication of debris within the side frame increases the braking efficiency of the railway vehicle as it reduces the amount of force necessary for applying the brake shoes to the wheels.Type: GrantFiled: May 11, 2016Date of Patent: January 2, 2018Assignee: Westinghouse Air Brake Technologies CorporationInventors: Michael Koziol, Scott Lee Natschke

Patent number: 9540021Abstract: 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.Type: GrantFiled: June 26, 2014Date of Patent: January 10, 2017Assignee: Wabtec Holding Corp.Inventors: Shaun T.
