Abstract:
A mud applicator for applying mud to wall board, which includes:a housing having a front open surface through which mud can pass, a plate pivotally movably connected within said housing such that said plate moves toward and away from said open surface, and wherein said housing has a mount member fixably disposed to said housing rearwardly of said plate with respect to said front open surface; anda pneumatic drive mechanism connected to said mount member and operably connected to said plate to cause said plate to move toward said open surface in a manner such that when mud is disposed in said housing, said plate forces said mud out of said front open surface and further includes means for automatically returning said plate toward said mount member, wherein said pneumatic drive mechanism includes a cylinder connected to said mount member and operatively disposed adjacent said plate, a piston operably reciprocally disposed in said cylinder such that said piston reciprocates in and out of said cylinder thereby contacting said plate in a driving manner toward said front open surface, and means connected to said cylinder for supplying pneumatic pressure to said cylinder and forcibly driving said piston toward said plate.
