Abstract
Abstract This invention in a preferred embodiment is directed to a truck or automobile having associated with at least one or more rear wheels, and preferably with also front wheels separate vessels, one for each wheel, actuateable by either brake or special actuation switch means or both to release vessel sand and/or salt contents through a directed outlet opening in front of the respective tires, and also behind the rear tires, the mechanism being separate for each of the front-of-tires release and the behind-tires release as controlled by the gear shift lever such that the anti-skid composition or mixture will be released on the track or path behind the tires only when backing and otherwise only in front of the tires when the vehicle is geared for forward motion, each vessel including a heating means for maintaining temperatures thereof and the contents thereof in an abovefreezing state and a vibrator associated with each vessel for facilitating gravity feed of solid contents of the vessel down an inclined wall and out of the outlet of the vessel, the vessel being mounted on rubber mounting structure itself mountable onto the vehicle, the period of actuation and feed being for typically one cycle of a one-cycle motor connected for revolving a feed gate at each vessel outlet opening for thereby feeding a controlled amount per actuation by virtue of a coil induction switch remaining closed for continuing a closed circuit until the one motor-cycle is completed, there being a master switch for activating and deactivating the entire system''s electrical circuitry.
