Abstract
A high pressure, airless paint spray gun having a body with a nozzle at the forward end, a reciprocating valve operator for the nozzle and a pivotal hand lever for operating the valve operator and permitting paint to flow through the nozzle. Dual safety devices are provided for preventing the accidental depression of the hand lever and the accidental discharge of high pressure paint from the nozzle. One safety assembly consists of a pivotally mounted thumb lever on the back of the gun body that selectively receives or blocks a stem projecting rearwardly from the valve operator. The other safety assembly includes a trigger pivotally mounted on the hand lever that grabs a projection extending downwardly from the body and selectively prevents accidental pivotal movement of the hand lever.
