Appl. No.:

09/747154

Inventors:

David Daugherty - Plainfield IL, US

International Classification:

B61G009/00

US Classification:

213/06200R, 213/050000

Abstract:

A retainer member for use in either an articulated coupling arrangement and/or a slackless drawbar arrangement for retaining a spherical member in an operating position within a male connection member for connecting together adjacently disposed ends of a pair of railway vehicles in a semi-permanent manner is provided. The retainer member comprises a one piece circular member which is engageable with at least a portion of an inner surface formed by an aperture in a modified male connection member. The circular member is engageable within this aperture of the male connection member to hold the spherical member within the aperture of the male connection member and to form a substantially spherical surface upon which the spherical member rotates against, enabling the male connection member to rotate with respect to the female or car connection member of the railway coupling device.

Abstract:

A device for providing self-lubrication to a slackless coupling system for a railway vehicle, specifically an articulated connector. The device comprises a self-lubricating member having a predetermined size and shape. The self-lubricating member is integrally formed from a non-stick material. The self-lubricating member has an inner surface and an outer surface, whereby such non-stick material will provide sufficient lubrication between the inner surface of the self-lubricating member, and a first surface of a spherical member coming in contact with the inner surface of the self-lubricating member, thereby allowing unrestricted movement of such spherical member there against, thus causing a reduction in L/V ratio when such self lubricating member is used in such coupling system.

US Classification:

213 75R

Abstract:

A male connection member utilized in an articulated coupling arrangement is provided by this invention. Such male connection member includes a first end portion engageable with and connectable to one end of a railway car to be connected in a semi-permanent manner. This male connection member has a second end portion formed integrally with such first end portion and disposed axially opposite thereof. The second end portion includes an outer end surface configured such that it will ensure that no contact will be made between such outer end surface and any other component of such articulated coupling arrangement. An aperture is formed through such second end portion to receive a bearing assembly therein. Such aperture has a longitudinal axis disposed transverse to a longitudinal axis of such male connection member and is in a substantially horizontal plane. A portion of such second end is adapted to enable securing such bearing assembly within such aperture formed in such male connection member.

International Classification:

B61G 502

US Classification:

213 75R

Abstract:

The present invention provides a strengthening mechanism for a female connection member used in a articulated coupling arrangement. Such female connection members include a first end portion configured for connection to one end of a railway car center sill member and a second end portion formed integrally with such first end portion. A cavity is formed in such second end portion and is defined by a bottom wall portion, a rear wall portion and a pair of side wall portions. Such cavity being open adjacent the front and top surface thereof. An opening is formed through a portion of each of such side wall portions. Each such opening includes a slot-like portion and a generally arcuate portion spaced below such slot-like portion. At least one strengthening mechanism is formed integrally with at least one of such pair of side wall portions adjacent such second end portion and is disposed adjacent such slot-like portion adjacent such top surface of such at least one of such pair of side wall portions to provide the requisite amount of force absorbing capability to such female connection member during service in a train consist.

International Classification:

B61H 1300

US Classification:

188 52

Abstract:

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. The jaw member portion of the slack adjuster is secured with the first portion of the J-shaped member such that a longitudinally disposed centerline of the slack adjuster is positioned a predetermined distance above a predetermined horizontally disposed plane of the transfer lever.

Abstract:

A friction clutch for a draft gear assembly includes two outer stationary plates having outer surfaces engageable with the inner surfaces of a gear housing. A slot formed in each outer stationary plate receives a lubricating insert to prevent clutch sticking after closure and during a release of such gear. A pair of movable plates have outer surfaces frictionally engaged with inner surfaces of such outer stationary plates for absorbing energy during closure of such gear. A pair of inner stationary plates have outer surfaces frictionally engaged with inner surfaces of such pair of movable plates for absorbing energy during such closure. An inner surface of each inner stationary plate is tapered. Another slot formed in each tapered stationary plate adjacent an outer surface receives another lubricating insert which prevents clutch sticking during release of the gear. A pair of wedge shoes having a tapered outer surface frictionally engage an inner surface of such tapered stationary plates for absorbing energy during closure.
