Patent number: 8469464Abstract: A parking brake assembly for a railway car includes a ratchet mounted for rotation on a threaded piston rod of a brake actuator and a holding pawl engageable with the ratchet for maintaining a push rod of the parking brake assembly to apply braking force when the air pressure is lost in the brake pipe and releasing the push rod to accordingly release the braking force when the supply of air pressure in the brake pipe is restored. An operating lever and a cylinder connected thereto are provided for selectively rotating the holding pawl. Valve is provided for supplying air pressure to and evacuating it from the cylinder. Release mechanism is provided for manually releasing the braking force. The parking brake assembly is employed with either truck-mounted or carbody-mounted braking system.Type: GrantFiled: July 6, 2011Date of Patent: June 25, 2013Assignee: WABTEC Holding CorpInventors: Howard Sommerfeld, Jonathon Marlow, Michael J.

Patent number: 7341128Abstract: A brake rigging for a railway vehicle having a singular truck-mounted brake apparatus for generating a braking force and a plurality of disk caliper assemblies for applying the braking force to each wheel. Wedge-like elements are rigidly attached to the braking beams of the truck-mounted brake apparatus and engage a pair of rollers that are pivotably mounted on corresponding ends of a pair of pivoted levers disposed within a disk caliper assembly. The wedge-like elements transmit a generated braking force to the levers, the rocking of which in opposite directions is effective to force the brake shoes against the respective opposite sides of a disc brake rotor to exert the braking force thereon.Type: GrantFiled: December 9, 2004Date of Patent: March 11, 2008Assignee: WABTEC Holding Corp.Inventors: Michael E.

Patent number: 6619443Abstract: An overload protection device for a truck-mounted railcar brake assembly, comprising a body member having a first end, a second end, and at least one cavity of a predetermined size and shape disposed within the body member. A compression member of a predetermined size, shape, material, and load rating is compressed to a predetermined initial load and disposed within the cavity of the body member. A first means is secured to and disposed on the first end of the body member for engagement with a portion of a brake assembly. A second means is disposed on the second end of the body member for attaching to a force-transmitting member. A first portion of the second means is engageable with the compression member for transmitting an excess force generated from such railcar brake assembly to the compression member, whereby the overload protection device will compensate for a potential railcar brake overload condition.Type: GrantFiled: June 7, 2001Date of Patent: September 16, 2003Assignee: Westinghouse Air Brake Technologies CorporationInventors: Michael E.

Patent number: 6148966Abstract: An adapter system for use in railway vehicle braking systems for increasing the height of a slack adjuster with respect to a force transfer lever in the braking system is provided. Increasing the height of the slack adjuster in the system results in better clearance of the slack adjuster through an opening of the truck bolster through which the slack adjuster extends in single-cylinder, truck-mounted braking systems. The adapter system of the invention comprises a J-shaped member which is engageable with the transfer lever of the braking system. This J-shaped member has a first portion extending above and substantially parallel with at least a portion of the transfer lever, a second portion positioned below an end of the transfer lever, and a third portion positioned adjacent an edge of the end of the transfer lever. The transfer lever is connected between the first and second portions of the J-shaped member.Type: GrantFiled: March 22, 1999Date of Patent: November 21, 2000Assignee: Westinghouse Air Brake CompanyInventors: David W. Daugherty, Jr., Michael J. Moriarity, Eric S. Graves

Patent number: 5069312Abstract: A handbrake system for use with a truck-mounted, single-cylinder brake rigging including truss-type brake beams, there being a single handbrake pivotal lever supported intermediate its ends by a twisted transfer link that is, in turn, fixed to the brake rigging transfer lever. A fulcrum end of the handbrake lever is free to engage the bearing surface of a thrust block mounted on the brake beam at the juncture of the beam tension and strut members in order to allow the point of engagement between the fulcrum end and the bearing surface to change with rotation of the handbrake lever. In addition, the fulcrum end of the handbrake lever is arranged with two, spaced-apart arcuate segments that successively engage the bearing surface of the thrust block during rotation of the handbrake lever to change its lever ratio and, accordingly, limit the degree of rotation of the handbrake lever.Type: GrantFiled: October 15, 1990Date of Patent: December 3, 1991Assignee: Westinghouse Air Brake CompanyInventors: Wajih Kanjo, Mark S. Krampitz, Michael J. Moriarity
