US Patent:
8267229, Sep 18, 2012
Filed:
Nov 20, 2007
Appl. No.:
11/943266
Inventors:
Joseph C. Kahr - Southern Pines NC, US
Timothy A. Rumph - Laurinburg NC, US
Assignee:
RFPC Holding Corp. - Wilmerding PA
International Classification:
F16D 65/04
F16D 69/00
US Classification:
188251R, 188250 G, 188250 B, 188251 M
Abstract:
A brake shoe without a metal backing has a metal insert comprising two spaced apart bodies, a connecting portion having a back face adjacent to the back surface of the brake shoe, and two generally parallel radially extending flanges integral with the connecting portion. The parallel extensions define a keyway, wherein when the brake shoe is emplaced on the brake head, the keyway extends through an opening provided in the brake head.

US Patent:
20070151817, Jul 5, 2007
Filed:
Dec 6, 2006
Appl. No.:
11/567559
Inventors:
Joseph Kahr - Southern Pines NC, US
Joseph Formolo - Laurinburg NC, US
Assignee:
RFPC HOLDING CORP. - Wilmerding PA
International Classification:
F16D 69/00
US Classification:
18825000R
Abstract:
A railway brake shoe including a first layer constructed of a composition friction material and a second layer constructed of a resilient composition material. The second layer is joined to the first layer. The second layer is adapted to receive at least one mechanical fastener therein to removably secure the brake shoe to a brake head. The resilient material of the second layer is capable of applying a circumferentially compressive force to the at least one mechanical fastener and prevent breakage of the composition friction material at the attachment location and/or enlargement of the attachment apertures due to vibration and lateral impacts.

Brake Shoe With Insert Bonded To Backing Plate

View page
US Patent:
6241058, Jun 5, 2001
Filed:
Aug 6, 1999
Appl. No.:
9/369983
Inventors:
Bruce W. Shute - West End NC
Joseph C. Kahr - Southern Pines NC
Assignee:
Westinghouse Air Brake Company - Wilmerding PA
International Classification:
F16D 6504
F16D 6902
F16D 6904
US Classification:
188250B
Abstract:
A composition brake shoe for use on a railway vehicle for reconditioning a wheel tread surface during a normal braking application on such railway vehicle is provided. The composition brake shoe includes a backing plate having a stirrup and a brake surface having a predetermined configuration and a predetermined surface area. It further includes a first friction type composition material extending over the surface area of such brake surface of such composition brake shoe. The composition brake shoe further contains a second friction type material, formed as at least one discrete insert, having a predetermined shape and molded into such first friction type composition material. Such second friction type material initially being completely embedded within such first friction type composition material. One surface of such at least one discrete insert being incrementally exposed as such first friction type composition material is eroded away due to frictional engagement with such wheel tread surface during normal braking operations, such second friction type material exhibiting greater abrasive properties than such first friction type composition material. Such at least one discrete insert of such second friction type material is bonded to such backing plate.

Disc Brake Shoe Assembly

US Patent:
54292166, Jul 4, 1995
Filed:
May 13, 1994
Appl. No.:
8/242690
Inventors:
Joseph C. Kahr - Southern Pines NC
Assignee:
Westinghouse Air Brake Company - Wilmerding PA
International Classification:
F16D 6900
US Classification:
188250R
Abstract:
A disc brake shoe in which a relatively thin gage, low-cost metal backing plate has bonded to one face a friction brake lining and is formed on the opposite face with a plurality of straps that are adapted to engage corresponding recesses formed in a complementary thick gage metal backing plate to interlock the respective backing plates into a unitary brake shoe assembly which can be easily disassembled to permit change-out of a worn brake shoe by simply substituting a newly lined, low cost backing plate for the existing backing plate having worn lining without the need to re-claim the backing plate for re-use.

Brake Shoe Mounting System

View page
US Patent:
63022478, Oct 16, 2001
Filed:
Dec 22, 1999
Appl. No.:
9/471533
Inventors:
Joseph C. Kahr - Southern Pines NC
Thomas W. McCabe - Southern Pines NC
Assignee:
Westinghouse Air Brake Company - Wilmerding PA
International Classification:
F16D 6504
US Classification:
188248
Abstract:
A brake shoe mounting system for railway vehicles includes a composition type brake shoe having a recessed center portion and two bracket-style backing plates integrally molded into the composition type brake shoe. There is one bracket style backing plate per each half of the brake shoe. Each bracket style backing plate further includes at least two projections extending outwardly from the convex surface of the composition brake shoe. The two projections extending outwardly are closely adjacent a first end of the brake shoe and at least one projection extends outwardly from the convex surface of the brake shoe closely adjacent the recessed center portion of the composition type brake shoe. The mounting system further includes a brakehead having a concave surface with a central projection for engaging the recessed center portion of the convex surface of the brake shoe. The brakehead includes a first recessed area closely adjacent a first end of the brakehead for receiving projections extending outwardly from the backing plate and a second recessed area closely adjacent the central projection for receiving the one projection extending outwardly from the backing plate.

Brake Shoe Having Fatigue Resistant Backing Plate

View page
US Patent:
55952674, Jan 21, 1997
Filed:
Jun 11, 1996
Appl. No.:
8/661820
Inventors:
Joseph C. Kahr - Southern Pines NC
Assignee:
Westinghouse Air Brake Company - Wilmerding PA
International Classification:
I16D 6900
US Classification:
188261
Abstract:
A composition type brake shoe for a railroad car in which the backing plate keybridge is filled with composition brake lining material to reinforce the keybridge. A recess formed in the braking face of the brake lining extends beyond the keybridge so that a relatively thin area of brake lining is formed between the recess and backing plate outboard of the keybridge opening, and to which thin section area cracks that may develop in the brake lining are encouraged to migrate in order to redirect backing plate flexure away from the critical keybridge area to a stronger area of the backing plate.

Fatigue And Impact Resistant Railway Brake Shoe

US Patent:
57044546, Jan 6, 1998
Filed:
Mar 29, 1996
Appl. No.:
8/625179
Inventors:
Joseph C. Kahr - Southern Pines NC
Assignee:
Westinghouse Air Brake Company - Wilmerding PA
International Classification:
F16D 6504
US Classification:
188247
Abstract:
A bonded composition type railroad brake shoe is disclosed in which the keybridge cavity of the brake shoe backing plate is filled with composition brake lining material for reinforcement and dampening of the keybridge. An insert located in the keybridge cavity comprises a pair of spaced-apart ribs that are upturned from a base plate such that the insert partitions the keybridge cavity. The insert is bonded in place by the composition brake lining material, which is formed with a keyway by the insert. The insert further serves to reinforce the keybridge in conjunction with the composition brake lining material therein.
