An improved compressed air spray gun includes a conventional compressed air spray head unit connected to a mounting block. The mounting block is fabricated from an integral block of material and includes radially extending passageways intersecting within a medial portion of the mounting block and communicatively connecting at their intersection point with an outlet on the upper face of the mounting block which communicatively connects with the fluid inlet of the spray head unit. The passageways extend outwardly through the mounting block to form outlets on the peripheral side edge portions of the block. Fluid inlet ports are positioned on the lower face of the mounting block and extend into the block and communicate with respective ones of the passageways. Each fluid inlet port has connected thereto a fluid holding canister. A valve means is positioned in each of the radially extending passageways and controls the amount of fluid which can be delivered from an individual fluid holding canister so that the flow of fluid from each of the canisters can be individually and selectively regulated to spray singly or in combination the fluids contained within each canister.

An improved compressed air spray gun comprising a spray head unit having a nozzle outlet, a compressed air connection means adapted for communicatively connecting to a compressed air line, and a fluid inlet means adapted for communicatively connecting to a fluid line or fluid holding canister and adapted to draw liquid upwardly therethrough by a vacuum draw and mix with compressed air to be discharged from the nozzle outlet, an integral mounting block having upper and lower faces and peripheral side edge portions and an outlet on the upper face in a medial portion thereof and extending into said mounting block, said outlet communicatively connected to said fluid inlet means of said spray head unit, said mounting block including therein a plurality of radially extending passageways, extending into and through said mounting block and intersecting at said medial portion of said mounting block, and communicatively connecting at their intersection point thereof with said outlet on the upper face of said mounting block, a plurality of fluid inlet ports positioned on the lower face of said mounting block in spaced relation to each other and to said peripheral side edge portions, said fluid inlet ports extending into said mounting block and communicating with respective ones of said radially extending passageways, a plurality of depending fluid holding canisters having connection means for removable connection and communication to a spray head unit or fluid line to allow fluid or paint contained in said canister to be drawn upward by vacuum, said canisters being individually and removably connected by said connection means to individual ones of said fluid inlet ports so that a fluid flow path is established from each of said canisters through a respective passageway communicating therewith and into said spray head unit, and a valve means positioned in each of said radially extending passageways for controlling the amount of fluid which can be delivered from an individual fluid holding canister into the mounting block, whereby the flow of fluid from each of said canisters can be selectively regulated to spray singly or in combination the fluids contained within each canister.
