  • nozzles 1-11 are shown in a somewhat irregular array in Figure 1, in practice, said nozzles are located on a fifty foot spacing on the longitudinal center line of the building in which they are employed at a convenient height approximately ten to twelve feet above the floor. " Such positioning of nozzles may be altered to be used in other building designs in order to secure adequate spray coverage and yet be well within the scope of applicants invention. For example, in a one hundred foot shorter building than that described in Figure 1, line 50 would be unnecessary. Therefore, the exact number of nozzles may be increased or decreased depending upon the building size. Further, it may be possible to locate panel 22 and lines 24 and 26 at or near the center of a building thus running conduit from panel 22 and line 26 each direction along the longitudinal center line of the building, again without departing from the scope of applicants device.

  • Attached to the top of nozzle 118 is a barbed connector 124 like that earlier described in connection with Figures 1 and 2.
  • conduit 126 Connected to barbed connector 124 is conduit 126 which delivers pressurized air to the nozzle 118.
  • Conduit 126 preferably is of the 3/8" outside diameter ⁇ " inside diameter polyethylene tubing type earlier described in connection with Figures 1 and 2.
  • tube 126 is forced onto barbed connector 124 thus providing an air-tight connection.
  • Nozzle 118 is connected at its lower end via a barbed connector 128 and tube 130 with the interior of the pesticide bucket or container 120 and the liquid pesticide 132 contained therein.
  • the spray-head or nozzle assembly 118 is supported above container 120 by a support element 134 through which tube 130 runs.
  • Container or bucket 120 generally has been of the five gallon capacity but, of course, one of a larger or smaller capacity could be employed without departing from the scope of this invention.
  • Pesticide 132 may be Pyronyl Poultry House and Barn Fly Spray which contains by percentage the following: Pyrethrins 2%; Piperonyl, Butoxide, Tehnical 4%; N- octylbicycloheptenedicarboximide 6.66%; and Petrol distillates 87.34% in concentrated form. In practice the above pesticide is mixed and sprayed in a 1 to 4 mixture with No. 1 diesel fuel or deodorized kerosine.
  • Nozzle 118 operates by use of the compressed air coming through tube 126 and by siphon action through tube 130 to atomize the insecticide siphoned to the nozzle and to force the thus atomized pesticide through four orifices 122 to the space surrounding the nozzle.
  • the passage of the compressed air from 126 into nozzle 118 through its internal structure creates a siphon-like action which pesticide 132 from 120 into the nozzle 118 to be atomized and sprayed into the area about the nozzle.

  • the foregoing parts are available from the Spraying Systems Company and fit within the structure of nozzle 118.
  • the pressurized air passing through the nozzles draws pesticide from the respective containers into the nozzles when it is atomized and sprayed out the four orifices in each spray head to fumigate or "fog" the area around the nozzle.
  • the spraying or "fogging" action continues until the time set by the operator on timer 100 expires, at which time the valve 102 closes and the system stops operation. The operation is then repeated when it is desired to fumigate or "fog" the enclosed space again.
  • the system is thus easy to operate and exceedingly effective in the fumigation of enclosed spaces. Further, the system costs only about twenty percent of the price of competing systems.
  • a major reason that system is economical is the use of a single small sized distribution conduit in all lines of any significant length i.e., all lines of the system other than the few feet of conduit (e.g. 24 and 26) immediately associated with the control equipment.
  • the system cost can be greatly reduce.
