ABSTRACT:
A brake pipe end cock provided with a pair of operating handles disposed respectively on opposite sides of the end cock, whereby the end cock may be operated from either side of the car, because one handle, which is self-locking on one side, is connected by a crossover bar to the other handle on the opposite side, which may or may not be self-locking, as desired, to provide concurrent movement of the two handles as a unit, said crossover bar being necessary to unlock the self-locking handle in order to effect operation of the valve device if the non-locking handle is the one manipulated.
