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.

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.

US Classification:

213 62R

Abstract:

This invention provides a locking wedge assembly capable of exerting a predetermined pressure in at least one direction. Such assembly removably secures a male connection member to a female connection member of an articulated coupling arrangement. Such articulated coupling arrangement used to secure one end of a first railway car to an adjacent end of said railway car in a semi-permanent fashion. The assembly includes a wedge-shaped member having a surface engageable with a surface located in an opening in a side wall portion of a cavity at an outer end of the female member and another surface engageable with a surface on a shaft member of a spherical bearing carried by such male member. An aperture is formed through such wedge-shaped member along a longitudinal axis thereof. A bolt member is disposed through this aperture and an aperture formed through a bottom wall on the outer end of such female member adjacent the side wall opening.

Abstract:

This invention provides a connecting pin member which facilitates a rotatable connection being achieved between a female connection member and a center bowl portion of a bolster. Such connecting pin member has a substantially round rod-like member which is tapered at each outer end thereof. A groove-like portion carrying a resilient member is disposed in an outer surface of such rod-like member. The present invention further provides a method of producing such connecting pin member as well as an improved center plate member for use with such connecting pin member. Such center plate member incorporates an arrangement for the removal of such connecting pin member if it should be accidently sheared off during service.
