The spray gun also includes a removable motor, a forearm rest, an adjustable nozzle and a corresponding stand with a bottom base, an upright vertical backing and a c-shaped top that secures the drywall spray gun in place while the drywall material is poured into the hopper. ## Claims ### Claim 1 A drywall spray gun that disperses drywall material, comprising: a hopper that receives said drywall material to be dispersed by said spray gun; a casing that houses a flip lever and a fan that cools said casing and said drywall material when moving through said casing; a slide lock trigger that is disposed below said casing and disperses said drywall material in said hopper to a desired location when depressed; a trigger shield that is disposed below said casing and protects said slide lock trigger from being struck or touched unintentionally; a rechargeable battery pack that includes a pair of rechargeable batteries that is connected to said casing by a handle and provides electrical power to said drywall spray gun; a removable motor that provides power to the drywall spray gun to disperse drywall material; a forearm rest that is disposed on a rear portion of said casing and provides an area to be used by a user with a pair of forearms to rest said forearms on while dispersing said drywall material; an adjustable nozzle that is disposed on a proximal end of said casing and includes a plurality of adjustable openings to accommodate and dispense a plurality of different said drywall material; and a corresponding stand with a bottom base, an upright vertical backing and a c-shaped top that secures said drywall spray gun in place while said drywall material is poured into said hopper. ### Claim 2 (depends on 1) The spray gun according to claim 1, wherein said hopper includes a lid lock. ### Claim 3 (depends on 1) The spray gun according to claim 1, wherein said hopper has a rounded pouring edge and a triangular-shaped pouring edge to pour said drywall material out of said hopper if needed. ### Claim 4 (depends on 1) The spray gun according to claim 1, wherein said hopper has a handle and an ergonomic tab to grasp and maneuver said hopper. ### Claim 5 (depends on 1) The spray according to claim 1, wherein said hopper is funnel-shaped. ### Claim 6 (depends on 1) The spray gun according to claim 1, wherein said flip lever is in contact with said slide lock trigger when said slide lock trigger is depressed to activate said drywall spray gun to disperse said drywall material that is contained in said hopper. ### Claim 7 (depends on 1) The spray gun according to claim 1, wherein said rechargeable battery pack includes a plug-in charger unit. ### Claim 8 (depends on 1) The spray gun according to claim 1, wherein said upright vertical backing receives and accommodates said drywall spray gun as said drywall spray gun is placed against said upright vertical backing. ### Claim 9 (depends on 1) The spray gun according to claim 1, wherein said c-shaped top accommodates and stabilizes said hopper of said drywall spray gun as said drywall material is poured into said hopper. ### Claim 10 A drywall spray gun that disperses drywall material, comprising: a funnel-shaped hopper with a top perimeter that receives said drywall material to be dispersed by said spray gun; a casing that houses a flip lever and a fan that cools said casing and said drywall material when moving through said casing; a slide lock trigger that is disposed below said casing and disperses said drywall material in said hopper to a desired location when depressed; a trigger shield that is disposed below said casing and protects said slide lock trigger from being struck or touched unintentionally; a rechargeable battery pack that includes a pair of rechargeable batteries that includes a plug-in charger unit that is connected to said casing by a handle and provides electrical power to said drywall spray gun; a removable motor that provides power to the drywall spray gun to disperse drywall material; a forearm rest that is disposed on a rear portion of said casing and provides an area to be used by a user with a pair of forearms to rest said forearms on while dispersing said drywall material; an adjustable nozzle that is disposed on a proximal end of said casing and includes a plurality of adjustable openings to accommodate and dispense a plurality of different said drywall material; and a corresponding stand with a bottom base, an upright vertical backing and a c-shaped top that secures said drywall spray gun in place while said drywall material is poured into said hopper. ### Claim 11 (depends on 10) The spray gun according to claim 10, wherein said hopper includes a lid lock. ### Claim 12 (depends on 10) The spray gun according to claim 10, wherein said hopper has a rounded pouring edge and a triangular-shaped pouring edge to pour said drywall material out of said hopper if needed. ### Claim 13 (depends on 10) The spray gun according to claim 10, wherein said rounded pouring edge and said triangular-shaped pouring edge are positioned 180 degrees across from each other along said top perimeter of said hopper. ### Claim 14 (depends on 10) The spray gun according to claim 10, wherein said hopper has a handle and an ergonomic tab to grasp and maneuver said hopper. ### Claim 15 (depends on 10) The spray gun according to claim 10, wherein said hopper has a capacity of approximately 2.0 gallons. ### Claim 16 (depends on 10) The spray gun according to claim 10, wherein said flip lever is in contact with said slide lock trigger when said slide lock trigger is depressed to activate said drywall spray gun to disperse said drywall material that is contained in said hopper. ### Claim 17 (depends on 10) The spray gun according to claim 10, wherein said rechargeable batteries are replaced with a charged lithium battery. ### Claim 18 (depends on 10) The spray gun according to claim 10, wherein said removable motor is an approximate 3,000 rpm removable motor. ### Claim 19 (depends on 10) The spray gun according to claim 10, wherein said upright vertical backing receives and accommodates said drywall spray gun as said drywall spray gun is placed against said upright vertical backing. ### Claim 20 (depends on 10) The spray gun according to claim 10, wherein said c-shaped top accommodates and stabilizes said hopper of said drywall spray gun as said drywall material is poured into said hopper.
