ABSTRACT:
The traction material dispensing apparatus mounts within the wheel well of a fender of a vehicle and is therefore visually and physically unobtrusive. The apparatus selectively dispenses traction material both in front of and behind a vehicle tire. A driver-accessed switch controls the apparatus dispensing of material. Of importance is that the manifolds, funnels, and nozzles are gravity fed by the vessel so that agitators and pressurized material flow assistance is not needed. Flappers within each manifold are controlled by the driver-actuated switch and control delivery of the traction material to the nozzles. As with the flappers, flow from the nozzles is controlled by a miniature DC (direct current) motor powered by the vehicle's electrical system. Screens ensure breakup of any clumps and therefore proper dispersion of traction material to the roadway.
