Abstract

An apparatus and method for improving the application of air brakes in the event a driver fails to apply the brakes upon exiting the driver area. The vehicles brakes will be applied automatically in the event the driver forgets. This will be done by blocking the air flow and exhausting the air that is present in the lines. The air will not be restored to said vehicle until the driver is back in control of this vehicle and manually resets the brake valve.

Claims

1. An electrically controlled and pneumatic system to stop the air flow to the brakes and at the same time evacuate the air present in said lines to allow the springs inside the tractor valve to take over and keep the vehicle from moving. This will be done whenever the driver activates a sensing switch by leaving the control position inside the vehicle and will need to be present to manually reset brakes before vehicle will move.

The electrical part of claim 1 is the power source that will supply the needed power to start activation.

The electrical part of claim 1 will be supplied to the system by means of an electrical conductor.

The electrical conductor in claim 1 will supply electricity to the sensing switch.

The sensing switch in claim 1 when activated will supply power to the relay coil.

The relay coil in claim 1 will activate and close or open a set of contacts contained within.

The relay coil in claim 1 will close a set of normally open contacts.

The contacts in claim 1 will supply power to a pneumatic solenoid coil.

The pneumatic solenoid coil in claim 1 will activate a valve body.

The relay coil in claim 1 will close a second set of contacts supplying power to a pneumatic coil.

2. The air reservoir tank in FIG. 2 Pneumatic Auto Brake Set-Air Brake series is comprised of air lines and tees needed to supply the air to the brakes or take the air present and evacuate it into the atmosphere.

Upon activation by the claim 1, these valves will shift to be in their normal state and will shift back to the opposite position upon de-activation of claim 1. Thus allowing normal operation of the brakes but requiring the driver to be present in the control position of said vehicles.

The air line is the delivery system that connects the air tank in claim to the rest of the system.

The solenoid valve body upon activation will close not allowing any more air to proceed past that point.

The airline four position tee in claim 2 is used to connect to more than one pneumatic solenoid valve.

There are two separate solenoid valves used to exhaust and evacuate the air pressure present at that point.

Is the atmosphere release of the air present in both solenoids in claim 2.

This is a tractor valve that is common in all air operated equipment and is in drawing for illustration purposes only. This valve is supplied by the O.E.M.
