A portable liquid pesticide transfer assembly capable of being removably mounted on a side wall that extends upwardly from a bed portion of a conventional pickup truck. The assembly when so mounted permits liquid pesticide to be transferred through a closed system from the container in which it is marketed to a tank for dispensing purposes without danger of the pesticide contacting the user or the user being subjected to the fumes thereof. The container after the pesticide is removed therefrom is capable of being washed together with the assembly, without the user being subjected to inadvertent contact with the pesticide containing wash water. The assembly includes a closure for removably sealing the container when the container has a quantity of pesticide remaining therein.

In combination with a flat bed truck that has a side wall extending from said bed, a drum that holds a toxic liquid pesticide and has an opening defined by a circular upwardly extending bead in an upper portion thereof, a wash water containing drum that may be disposed adjacent said flat bed, and a tank to which the pesticide is to be dispensed, a portable assembly capable of being removably supported from said side wall for selectively transferring said pesticide in a closed path either directly from said drum when the latter is adjacent said sidewall, said assembly including: a. a closure assembly that includes a cup-shaped body insertable in said opening in said drum, said body having at least one longitudinal port therein, a first tube that extends downwardly from said cup-shaped body and supported thereby that is in communication with the interior thereof, normally closed spring-loaded valve means in said first tube that is open when subjected to a downwardly directed force, and flange means that extend outwardly from said body that sealingly and removably engage said bead to hold said closure assembly on said drum; b. first, second, third, fourth, fifth, sixth, seventh and eighth valves; c. a pump that has a suction and discharge opening; d. a fixture assembly that includes a shell that defines a confined space, a second tube that extends from said shell and is in communication with the interior thereof, said second tube removably sealing with the interior of said cup-shaped body, a tubular probe that extends through said shell and said second tube and cooperating with the latter to define an annulus-shaped space that is in communication with said confined space and the interior of said drum, lock means that removably secure said shell in communication with said confined space; e. an elongate vertically disposed metering cylinder that has longitudinal graduations thereof that indicate the volume of pesticide in said cylinder, said cylinder having a top that has first and second openings therein and a bottom that has a third opening therein; f. first, second, third, fourth, fifth, sixth, seventh, and eighth conduits, said first conduit connected to said first opening and first valve; said second valve connected to said second opening and second valve; said third conduit connected to said second valve and said wash water drum; said fourth conduit connected to said third conduit and said opening in said shell and having said eighth valve therein; a fifth conduit extending from said probe to said suction of said pump, said fifth conduit having said seventh, third and fifth valves therein; a sixth conduit extending from said fifth conduit between said fifth valve and suction of said pump to said first conduit, said sixth conduit having said sicth valve therein; a seventh conduit extending from said discharge of said pump to said dispensing tank, and an eighth conduit extending from said fifth conduit between said third and fifth valves to said third opening, said eighth conduit having said fourth valve therein; and the suction created when said pump operates causing liquid pesticide to flow from said drum in which it is contained to said dispensing tank when said seventh, third and fifth valves are open and the balance of said valves closed; said pump when said seventh, third and fourth valves are open and the balance of said valves closed causing liquid pesticide to flow from said drum in which it is contained to said cylinder to have a desired quantity of said pesticide in said cylinder; said pump when said first, fourth and fifth valves are open and the balance of said valves closed transferring liquid pesticide from said cylinder to said dispensing tank; said pump when said eighth, seventh, third and fifth valves are open and the balance of said valves closed causing wash water to flow from said wash water drum through said third conduit, fourth conduit, confined space in said shell, said annulus space, said longitudinal port, the interior of said pesticide containing drum, said probe, said fifth conduit, pump and seventh conduit to said dispensing tank, and said pump when said second, fourth and fifth valves are open causing wash water to flow from said wash water drum through said third and second conduits to wash the interior of said cylinder and discharge therefrom through said eighth conduit, portion of said fifth conduit, pump and seventh conduit to said dispensing tank; g. a frame that supports said cylinder and at least a portion of said valves and conduits; and h. first means for removably supporting said frame from a side wall of a flat bed of an automotive vehicle.
