Barlow's patent "relates to an improved self-acting car-coupling by which two cars can be connected together without the presence of an attendant to enter the link as the bumpers come together, thus preventing many accidents." Intended for railroad car usage, his "improvement consists of a simple attachment which can be readily applied to the draw-heads at present in use, by which the pin or bolt which confines the ends of the link in the draw-head is held in the proper position to permit the entering link to automatically release it and allow it to drop through the link to the holding position." (Patent Number 133,006)
