Car-Coupling. (open access)

Car-Coupling.

Patent for a simple and inexpensive car-coupling that improves on the pin-and-link car-couplings and "will be capable of coupling automatically and which may be readily uncoupled without going between cars" (lines 13-15). After the car has been separated, this coupling automatically puts its parts in position to be re-coupled. It also enables a "flying kick" to be transmitted to the car.
