Sand dispensing device having plural compartments

Claim 2

A sand dispensing device for use on vehicles, comprising: a housing; said housing having an open top portion provided with a selectively closable cover; a carrying handle on said housing; a partition forming two compartments in said housing; a supply of sand in a first of said compartments; an electric air compressor in a second of said compartments; a relay in said second compartment operatively connected for energizing said compressor; a remote switch operatively connected for selectively closing said relay; means biasing said switch to an open position; an air supply tube connected to an output of said air compressor; an induction nozzle in said second compartment connected to said air supply tube; said induction nozzle having a sand inlet extending horizontally through an aperture in said partition into said sand in said first compartment; said induction nozzle having an air inlet disposed coaxially with said outlet, said sand inlet extending perpendicular to said air inlet and outlet, a connecting wall within said induction nozzle tapering forwardly toward said outlet; an outlet tube in said second compartment having a first end connected to an outlet of said induction nozzle and a second end extending through a side wall of said housing; a pair of discharge tubes connected to said second end of said outlet tube by quick release connection means; and a pair of discharge nozzles on said discharge tubes for spraying a sand and air mixture adjacent drive wheels of a vehicle.

Claim 3

A sand dispensing device for use on vehicles, comprising: a housing; said housing having an open top portion provided with a selectively closable cover; a carrying handle on said housing; a partition forming two compartments in said housing; a supply of sand in a first of said compartments; an electric air compressor in a second of said compartments; a relay in said second compartment operatively connected for energizing said compressor; a remote switch operatively connected for selectively closing said relay; means biasing said switch to an open position; an air supply tube connected to an output of said air compressor; a pair of induction nozzles in said second compartment connected to said air supply tube; said induction nozzles each having a sand inlet extending horizontally through an aperture in said partition into said sand in said first compartment; a pair of outlet tubes in said second compartment each having a first end connected to an outlet of one of said induction nozzles and a second end extending through a side wall of said housing; each of said induction nozzles having an air inlet disposed coaxially with said outlet, said sand inlet extending perpendicular to said air inlet and outlet, a connecting wall within said induction nozzle tapering forwardly toward said outlet; a pair of discharge tubes connected to said second ends of said outlet tubes by quick release connection means; and a pair of discharge nozzles on said discharge tubes for spraying a sand and air mixture adjacent drive wheels of a vehicle.

Claim 4

A sand dispensing device for use on vehicles, comprising: a housing; said housing having an open top portion provided with a selectively closable cover; a carrying handle on said housing; a partition forming two compartments in said housing; a supply of sand in a first of said compartments; an electric air compressor in a second of said compartments; a relay in said second compartment operatively connected for energizing said compressor; a remote switch operatively connected for selectively closing said relay; means biasing said switch to an open position; an air supply tube connected to an output of said air compressor; a pair of induction nozzles in said second compartment connected to said air supply tube; said induction nozzles each having a sand inlet extending horizontally through an aperture in said partition into said sand in said first compartment; a pair of outlet tubes in said second compartment each having a first end connected to an outlet of one of said induction nozzles and a second end extending through a side wall of said housing; each of said induction nozzles having an air inlet disposed coaxially with said outlet, said sand inlet extending perpendicular to said air inlet and outlet, a connecting wall within said induction nozzle tapering forwardly toward said outlet; a pair of discharge tubes connected to said second ends of said outlet tubes by quick release connection means; and a pair of discharge nozzles on said discharge tubes for spraying a sand and air mixture adjacent drive wheels of a vehicle.
