Publication number: 20040183368Abstract: The present invention discloses a hand brake mechanism having a gravity based release hold mechanism with a visual indicator to prevent unwanted application of the railcar brakes and indicate such release hold condition. The release hold mechanism comprises a gravity based member pivotally linked to a release shaft preventing reverse rotation of the release shaft causing an unintended take-up of the chain. A detent retaining device disposed within the railcar hand brake housing further provides improve reliability of the operation. The gravity based member incorporates an indicator portion having a reflective coating to indicate such release hold position of the railcar hand brake.Type: ApplicationFiled: March 21, 2003Publication date: September 23, 2004Inventors: Staffan Brandt, Howard Sommerfeld, Scott Natschke, Wajih Kanjo

Patent number: 6761253Abstract: A spring applied parking brake assembly for a railway vehicle is provided which automatically activates upon removal of a railway car from the pneumatic braking system of the railway vehicle. The spring applied parking brake assembly comprises a casing which is mounted on or within the braking system, typically alongside the air cylinder. This casing contains a spring member and a piston assembly, both of which are mounted for longitudinal movement within the casing upon the application and/or removal of pneumatic pressure within the casing. The piston assembly includes a piston rod which is associated with the force transfer lever of the braking system such that upon a removal of pneumatic pressure within the casing, longitudinal movement of the piston rod causes this force transfer lever to rotate and apply a force to at least one force transmitting member in the vehicle braking system to initiate a brake application.Type: GrantFiled: February 24, 2000Date of Patent: July 13, 2004Assignee: Westinghouse Air Brake CompanyInventors: Wajih Kanjo, Scott Natschke

Publication number: 20030111897Abstract: An automatic application hand brake mechanism is provided for automatically applying at least one brake member secured to a railway vehicle with the hand brake assembly. The mechanism comprises an operating member having at least one ratchet. The at least one ratchet is engageable with at least one gear of a gear assembly disposed in a housing member of the hand brake assembly for operating the gear assembly in a direction which will cause an application of the at least one brake member. The apparatus also includes an application cylinder mounted on the railway vehicle and a drive arm extending from an end of the application cylinder. The drive arm has a first portion which is connected to the operating member. The drive arm is capable of reciprocating with respect to the application cylinder upon the application of a force thereto to supply a predetermined pressure to the operating member at least a sufficient amount so as to cause an application of the at least one brake member.Type: ApplicationFiled: August 13, 2002Publication date: June 19, 2003Inventors: Michael E. Ring, Scott Natschke, Robert Herron

Patent number: 6394233Abstract: An apparatus for operation a railway car vertical wheel hand brake. A hand brake wheel has a hub fixed on an operating shaft. The operating shaft is rotatably mounted on the hand brake. The hand brake wheel further has a reaction member. A brake release mechanism is fixed on a brake release shaft that is rotatably mounted on the hand brake. The reaction member is engageable with the brake release mechanism when the hand brake wheel is rotated, whereby the position of the brake release mechanism will provide a visual indicator of the brake status.Type: GrantFiled: July 13, 2001Date of Patent: May 28, 2002Assignee: Westinghouse Air Brake Technologies CorporationInventors: Wajih Kanjo, Michael E. Ring, Scott Natschke
