Claim 1

A fluid dispensing apparatus comprising a housing having a manually grasping handle; a manually movable trigger mounted adjacent said handle; means defining a plurality of fluid-containing chambers in said housing, each of said chambers containing a fluid having a characteristic different from the characteristics of the fluids in the other chambers; a plurality of laterally spaced nozzles mounted in said housing and pointing in the same general direction, said nozzles being oriented so that the central axes thereof intersect at a point which is a predetermined distance from said housing; a plurality of barrels, equal in number to the number of nozzles, slidably mounted in said housing for movement between retracted and extended positions, each of said barrels having one of said nozzles mounted at an end thereof; spring means urging each of said barrels toward its extended position; and releasable latch means for holding said barrels in their retracted positions, said latch means being released by manual movement of said trigger; fluid conduit means interconnecting each of said chambers with one of said nozzles for delivering fluid from said chambers to said nozzles, respectively; means for concurrently applying pressure to the fluid in all of said fluid conduit means in response to movement of said trigger to force fluid under pressure from said chambers through said conduit means and out of said nozzles, thereby forming a plurality of fluid streams which intersect at said point so that said fluids can interact.
