Touncouple, the pin or lock is revolved a frac-tion of a revolution by means of the handleon top of the coupler. The lock on eachcoupler must be unfastened in this way andthen the couplers can be pulled apart. In theact of uncoupling, the locks are automatic-ally thrown back into a coupling position sothat no further attention to them is required. The cam on thelock against which the spring presses is of such a shape that,when the locks are pulled clear around to uncoupling position,they will remain there until the locks are partially revolved in MOTOR CARS.
