Vehicle all-weather braking aid
First Claim
1. An all-weather braking aid system for a vehicle having a brake mechanism wherein a mechanical brake releases air pressure from a tank through a relay valve, which system comprises:
- motion detector means to swing freely in response to inertia of said vehicle;
sensor means operatively engaged with said motion detector means;
oscillating timer means activated by said sensor means;
valve means in advance of said relay valve to regulate said air pressure, said valve means normally in an open position to allow flow of said air pressure and movable to a closed position to interrupt said air pressure; and
switch means activated by said oscillating timer means in order to close said valve means for one selected duration and then open said valve means for another selected duration, thereby providing controlled intermittent braking.

Abstract
An all-weather braking aid for a vehicle having brakes actuated by air pressure. The all-weather braking aid includes at least one motion detector responsive to inertia of the vehicle. A sensor is operatively engaged with the motion detector and a switch is activated by the sensor. The pressurized air is directed to a valve, the valve is normally in an open position to allow flow of the air pressure and movable to a closed position to interrupt the air pressure. The timer is engaged with the switch in order to close the valve for one selected duration and then open the valve for another selected duration, thereby providing controlled intermittent braking.

19. A method of controlled intermittent braking for a vehicle having a brake mechanism wherein a mechanical brake releases air pressure from a tank through a relay valve, which method comprises:
-
(a.) sensing forward inertia or lateral inertia of said vehicle by sensor means which are activated by movement of motion detector means allowed to swing freely in response to said inertia; (b.) supplying electrical power responsive to inertia to oscillating timer means in response to said forward inertia or lateral inertia; (c.) intermittently supplying said power to switch means by said oscillating timer means; and (d.) regulating said air pressure by a valve in advance of said relay valve controlled by said switch means in order to close said valve means for one selected duration and then open said valve means for another selected duration, thereby providing controlled intermittent braking.
