| 121 | Railroad car coupler alignment device | US602803 | 1984-04-23 | US4586620A | 1986-05-06 | Russell J. Andrews |
| An alignment device for railroad car couplers including a central flexible portion with a pair of swivelable end portions connectable between couplers of adjacent cars. Each of the end portions includes a protruding stud adapted to engage an opening preformed in the knuckle body. The device end portions and their studs are inserted between misaligned adjacent couplers. One steady pull of the engine aligns the couplers so that two cars may then be quickly joined together without requiring the trainman to stand between the cars during the coupling operation. | ||||||
