Abstract
A rotary railroad car coupler is described as having a rotary connector with a spherical butt end for seating engagement in a spherical cavity formed in an adjacent front follower.
Claims7
A rotary coupler, comprising:
- (a) a yoke having an opening in the front end thereof;
- (b) a front follower disposed in the yoke in spaced relation from the opening in the front end and having a concavity recessed therein and facing the opening in the front end;
- (c) a connector rotatably mounted in the yoke between the opening in the front end and the front follower, the connector having a butt end which is matingly configured for seating engagement in the concavity of the front follower;
- (d) a coupler head having a shank extending therefrom through the opening in the front end of the yoke into the connector;
- and
- (e) means for mounting the coupler shank to the connector for unitary rotation therewith.

A rotary coupler, comprising:
- (a) a yoke having a longitudinal axis and an opening in the front end thereof;
- (b) a front follower disposed in the yoke in spaced relation from the opening in the front end and having a spherical concavity facing the opening in the front end;
- (c) a connector having a convex spherical butt end for seating in the spherical concavity of the front follower, the connector being mounted in the yoke between the opening in the front end and the front follower for rotation about its longitudinal axis which parallels the longitudinal axis of the yoke, the area of the spherical butt end of the connector being greater than the spherical concavity of the front follower, the connector being restricted for radial movement relative to the longitudinal axis of the connector and for axial movement longitudinally of the yoke and the connector having a spherical concave seat in spaced relation from the convex spherical butt end thereof;
- (d) a coupler head having a shank extending therefrom through the opening in the front end of the yoke into the connector, the shank having a convex spherical butt for seating engagement in the spherical concave seat of the connector;
- and
- (e) means for mounting the coupler shank and the connector for unitary rotation.
