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.
