Blast wiper for motor vehicle lights
First Claim
1. A blast wiper for cleaning snow from a light of a vehicle having a compressed air system, said blast wiper comprising essentially,automatic control means for regulating a flow of air from said compressed air system into intermittent gushes of air, said automatic control means comprising a first timer for regulating a span between said gushes of air, and a second timer for regulating a duration of each of said gushes of air,supply tubing means for connecting said automatic control means to said compressed air system,nozzle means for directing said intermittent gushes of air toward a surface of said light, anddelivery tubing means for connecting said automatic control means to said nozzle means,whereby said intermittent gushes of air maintain said light of said vehicle visible when said vehicle is driving in snowy condition, and said automatic control means prevents a continuous outflow of air from said compressed air system.

Abstract
A wiping system for cleaning snow accumulating on the rear signalling lights of a vehicle, using intermittent blasts of air. The blast wiping system comprises timers and a solenoid valve for regulating a flow of air from the air reservoir of the vehicle into intermittent gushes of air. The wiping system comprises also supply tubing for connecting the solenoid valve to the air reservoir of the vehicle, nozzles for directing the intermittent gushes of air toward a surface of the vehicle'"'"'s lights, and delivery tubing for connecting the solenoid valve to the nozzles. Each nozzle of the blast wiping system is placed near a lower quadrant of the light surface. Each nozzle is further oriented to deflect a gush of air in a tangential upward direction relative to the surface of the light, whereby a layer of snow on that surface is lifted off and blown away in a patch-like formation. The components of the blast wiping system are pre-wired and pre-tubed such that an installation thereof on a vehicle by a person unexperienced with pneumatic does not compromise the safety purpose of the compressed air system of the vehicle.

16. A retrofit kit for a blast wiping system for cleaning light lenses of a vehicle having a compressed air system, said retrofit kit comprising essentially,
a protection valve means for connecting to said compressed air system for preventing an outflow of air from said compressed air system when a pressure in said compressed air system is below a pressure setting of said protection valve, an automatic control means for regulating a flow of air from said compressed air system into intermittent gushes of air, a single supply line tubing means connecting said protection valve means to said automatic control means, nozzle means for directing said intermittent gushes of air toward a surface of said light lenses, and delivery tubing means for connecting said automatic control means to said nozzle means.
