The object of my invention is to arrange a coupling with valves in the same, especially applicable to the pipes connected with what is known as a vacuum-brake for steam railway-cars.
The common objection to a vacuum-brake has been that if one or more of the cars became detached from the rest of the train, the control over the train was utterly lost the moment a separation took place, because the efficacy of the brake depends on the vacuum in the pipes. If a single end be open the air cannot be sucked out. I therefore so arrange valves in the couplings that when the connection between the cars is made the valves will be held away from their seats, thus leaving a clear passage for sucking out the air and in case of the breaking apart of the cars, as would ordinarily happen in case of an accident, the valve in the coupling so separated will close, and thus the engineer retains full control over all the cars remainingin the train attachedto the locomotive, by the action of the pump on the enginein applying the vacuum pressure principle on the brakes.
When the couplings are connected together the pivoted lever G in the male pipe B is necessarily pressed down at its short point, and,
consequent on this movement, the long arm of the lever working through an eye on the valve, the valve 0 is raised from off its seat. In the female pipe A, when the connection is being made, the pivoted lever G is necessarily pressed upward at its short point, and conse- ..quent on this movement the valve 1] is raised from off its seat. When the couplings are connected the valves are held away from their seats, thus leaving a clear air-passage.
- When the couplings are disconnected, the valves go back to their seats. To aid this backward movement, I arrangea cross-head, D, in the pipe through which the back spindle E passes. Around the back spindle is a spiral spring, F. The proper working of the valves, however, in no way depends on the springs F, because when the engineer works the pump and sucks the air from the pipes to apply the brakes, the creation of a vacuum in the pipes brings into play the atmospheric pressure of, say, fifteen pounds to the square inch on the face of the valves, and so forces the valves backward to their seats and holds them there. 'But the arrangement of crosshead, spring, 850., is desirable in contributing to the neat working of the parts, as at the end of the train of cars, or when an accidental separation of cars takes place.
When the cross-head and spindle are notused, a simple device, such as a slot and pin, will prevent the valve from dropping out.
Rubber or other elastic packing may be used on the seats or other parts. A rubber ring, I, may be used outside to make the coupling joint absolutely air-tight.
Vfheu the male and female pipes are coupled, outside springs H H holdv them together. When the couplings are pulled asunder, the springs allow a separation without doing damage to any of the working parts. Each end of a car may be provided with a double set of connecting pipes and couplings.
My device makes an arrangement simple and efficient, not liable to get out of order, not expensive, and insures the proper working of a vacuum-brake under any and all circumstances.
Having thus described my invention, what levers G G, all arranged substantially in the I claim as new, and desire to secure by Letmanner and for the purpose herein described ters Patent, is-- and set forth.
