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.
Claims1
A brake pipe end valve device interposable between the end of a brake pipe and a brake pipe coupling hose of a railway car for controlling communication therebetween, said brake pipe end valve device comprising:
- a. a valve body mounted between the lateral limits of the car with the axis thereof disposed perpendicularly to the longitudinal center line of the car, and including a valve element selectively rotatably operable about said axis of said valve body to an open position, in which said communication is open, or to a closed position, in which said communication is closed;
- b. a pair of operating handles, one each being operably disposed on opposite sides of the valve body, each of said handles being accessible from the respective side of the car on which it is disposed;
- c. a crossover member rigidly connecting said handles to each other for causing unitary movement thereof, notwithstanding that only one of the handles is manipulated from one side of the car;
- d. respective key members interposed between said opposite sides of said valve element and the respective operating handles for transmitting rotating movement of the handles to the valve element;
- e. locking means cooperatively interposed between one of said operating handles and said valve body for locking said one of said operating handles and, therefore, said valve element against rotation and in the selected position until deliberately operated to the other of said open or closed position;
- f. a hinge connection by which said one of said operating handles is connected at one end to the adjacent key member and is pivotable thereabout for unlocking the handle against rotation;
- and
- g. a fulcrum connection connecting the other of said operating handles, between the ends thereof, to the other of said key members, said other of said operating handles having one end pivotally connected to the adjacent end of said crossover member for transmitting pivotal movement of said other of said operating handles, through said crossover member, to said one of said operating handles for effecting movement of the latter about said hinge connection and consequent unlocking thereof.
