Apparatus for blowing comminuted treating material onto plants and the like

Claim 1

AN APPARATUS FOR DELIVERING INTO THE ATMOSPHERE A JET OF AIR CARRYING COMMINUTED PLANT TREATMENT MATERIAL, THEREBY TO DIRECT A BLAST THROUGH THE ATMOSPHERE ONTO PLANTS AND THE LIKE, COMPRISING A CARRYING STRUCTURE, A BLOWER SECURED TO SAID STRUCTURE, AT LEAST ONE TANK CARRIED BY SAID STRUCTURE AND ADAPTED TO CONTAIN SUCH MATERIAL TO BE DISCHARGED IN COMMINUTED CONDITION, AND MEANS INCLUDING A NOZZLE BODY OF CIRCULAR CROSS-SECTION, SAID NOZZLE BODY HAVING A CLOSED END, AN INLET CONDUIT MEANS CONNECTED TO SAID BLOWER, SAID BODY HAVING ITS OPPOSITE, END OPENED TO CONSTITUTE A DISCHARGE END COMMUNICATING WITH THE ATMOSPHERE, SAID MEANS FURTHER INCLUDING A TUBE CONNECTED TO SAID TANK AND HAVING A DISCHARGE ORIFICE INTO SAID NOZZLE TO DISCHARGE SAID MATERIAL IN COMMINUTED CONDITION INTO THE CENTRAL REGION OF THE AIR FLOW FROM SAID BLOWER THROUGH THE NOZZLE WHEREBY AN AIR JET CARRYING SAID COMMINUTED MATERIAL IS DISCHARGED FROM THE NOZZLE INTO THE ATMOSPHERE, WHEREIN SAID NOZZLE INLET CONDUIT MEANS COMMUNICATES WITH THE NOZZLE BODY IN SUBSTANTIALLY TANGENTIAL RELATION THERETO AND THE NOZZLE BODY CONSTITUTES A MEANS FOR CAUSING SAID AIR FLOW FROM THE BLOWER TO BE FORMED IN THE NOZZLE BODY INTO A FREE SPIRAL VORTEX, WHEREBY THE JET DISCHARGED INTO THE ATMOSPHERE IS A ROTATING JET AND THE PRESSURES PREVAILING THEREIN ARE LOWER THAN THE ATMOSPHERIC PRESSURE.

Claim 2

AN APPARATUS FOR DELIVERING INTO THE ATMOSPHERE A JET OF AIR CARRYING COMMINUTED PLANT TREATMENT MATERIAL, THEREBY TO DIRECT A BLAST THROUGH THE ATMOSPHERE ONTO PLANTS AND THE LIKE, COMPRISING A CARRYING STRUCTURE, A BLOWER SECURED TO SAID STRUCTURE, AT LEAST ONE TANK CARRIED BY SAID STRUCTURE AND ADAPTED TO CONTAIN SUCH MATERIAL TO BE DISCHARGED IN COMMINUTED CONDITION, AND MEANS INCLUDING A NOZZLE BODY OF CIRCULAR CROSS-SECTION, SAID NOZZLE BODY HAVING A CLOSED END, AN INLET CONDUIT MEANS CONNECTED TO SAID BLOWER, SAID BODY HAVING ITS OPPOSITE, END OPENED TO CONSTITUTE A DISCHARGE END COMMUNICATING WITH THE ATMOSPHERE, SAID MEANS FURTHER INCLUDING A TUBE CONNECTED TO SAID TANK AND HAVING A DISCHARGE ORIFICE INTO SAID NOZZLE TO DISCHARGE SAID MATERIAL IN COMMINUTED CONDITION INTO THE CENTRAL REGION OF THE AIR FLOW FROM SAID BLOWER THROUGH THE NOZZLE WHEREBY AN AIR JET CARRYING SAID COMMINUTED MATERIAL IS DISCHARGED FROM THE NOZZLE INTO THE ATMOSPHERE, WHEREIN SAID NOZZLE INLET CONDUIT MEANS COMMUNICATES WITH THE NOZZLE BODY IN SUBSTANTIALLY TANGENTIAL RELATION THERETO AND THE NOZZLE BODY CONSTITUTES A MEANS FOR CAUSING SAID AIR FLOW FROM THE BLOWER TO BE FORMED IN THE NOZZLE BODY INTO A FREE SPIRAL VORTEX, WHEREBY THE JET DISCHARGED INTO THE ATMOSPHERE IS A ROTATING JET AND THE PRESSURES PREVAILING THEREIN ARE LOWER THAN THE ATMOSPHERIC PRESSURE.
