ABSTRACT:
A sand dispensing device designed to be carried in the trunk of a vehicle includes a housing having a partition forming two interior compartments. A supply of sand is stored in a first compartment and an electric air compressor is situated in a second compartment. A remote switch is operatively connected to a relay in the second compartment for energizing the compressor. An induction nozzle has a sand inlet extending through an aperture in the partition into the first compartment and is connected to an air supply tube connected to an output of the air compressor. An outlet tube in the second compartment has a first end connection to an outlet of the induction nozzle and a second end extending through a side wall of the housing. A pair of discharge tubes are connected by a quick release fitting to a second end of the outlet tube and a pair of discharge nozzles are provided on the discharge tubes for spraying a sand and air mixture adjacent drive wheels of the vehicle, to enhance traction on icy road surfaces. The device is conveniently removable from the vehicle trunk for replenishing the sand supply or for transferring between vehicles.
