APPARATUS FOR VARYING THE TIME BETWEEN INITIATION AND SUBSEQUENT RELEASE OF AN EMERGENCY BRAKE APPLICATION ABSTRACT OF THE DISCLOSURE Apparatus for varying the time between the initiation and subsequent release of an emergency brake application on a locomotive and train of cars hauled thereby comprises either fluid pressure operated valve means operable, by fluid under pressure supplied for causing knockout of the locomotive power supply, to establish communication between two reser- voirs, separably charged from the train brake pipe, whereby substantially all of the fluid under pressure must be released from both reservoirs to atmosphere via a first restricted com- munication prior to the release of an emergency application thereby increasing the time between initiating the emergency application and the subsequent release, or fluid pressure operated valve means operably responsively to power knockout to establish another restricted communication between a single reservoir and atmosphere whereby substantially all of the fluid under pressure must be released from the single reservoir to atmosphere via the two restricted communications simultane- ously prior to the release of an emergency application thereby decreasing the time between initiating the emergency applica- tion and the subsequent release thereof.
