Abstract
A spray applicator to discharge plaster or another texturizing material in a spray pattern against a wall surface or the like. There is a manually operable air cylinder and piston assembly which discharges pressurized air through a first nozzle, with an air jet traveling through an area where the plaster or the material descends from a container, with the air jet carrying some of the plaster through a forward discharge nozzle to cause a spray pattern. There is rotatable fluid discharge nozzle portion which is, by said rotation, moved toward and away from an air discharge nozzle.
Claims20
A spray applicator to discharge a fluid material in a spray pattern by means of pressurized air, said applicator comprising:
- a. a fluid discharge section comprising:
- i. a mounting portion;
- ii. a forwardly positioned fluid nozzle portion providing a fluid discharge nozzle means which is located on a longitudinally extending discharge axis;
- iii. said fluid discharge section defining a fluid discharge region located adjacent to and rearwardly of said fluid discharge nozzle means;
- iv. a fluid containing portion mounted to said mounting portion and adapted to contain said fluid material, said containing portion having a fluid discharge opening positioned to deliver said fluid material into said discharge region;
- b. an air pressurizing and supply section connected to said fluid discharge section and comprising:
- i. a housing defining an air chamber;
- ii. an air nozzle portion positioned at a forward end of said housing and providing an air discharge nozzle means which is located at said fluid discharge region rearwardly of said fluid discharge nozzle means;
- iii. a manually operable pressurizing member mounted in said housing for motion on a pressurizing stroke to provide pressurized air in said air chamber which is discharged through said air nozzle means to cause fluid material in said discharge region to be discharged through said fluid discharge nozzle means, and also for a return stroke;
- c. at least a portion of said fluid discharge section being arranged for forward and rear movement relative to said air pressurizing and supply section in a manner that said fluid discharge nozzle means moves toward and away from said air discharge nozzle means in a manner to control discharge of said fluid material through said fluid discharge opening means, each of said air pressure and supply section and at least said portion of said fluid discharge section being configured to be manually grasped so as to facilitate manually initiated movement toward and away from one another.

- ii. a forwardly positioned fluid nozzle portion providing a fluid discharge nozzle means which is located on a longitudinally extending discharge axis;
- iii. said fluid discharge section defining a fluid discharge region located adjacent to and rearwardly of said fluid discharge nozzle means;
- iv. said mounting portion having a mounting connecting means adapted to connect to a fluid containing portion adapted to contain said fluid material into said discharge region;
- b. an air pressurizing and supply section connected to said fluid discharge section and comprising:
- i a housing defining an air chamber;
- ii. an air nozzle portion positioned at a forward end of said housing and providing an air discharge nozzle means which is located at said fluid discharge region rearwardly of said fluid discharge nozzle means;
- iii. a manually operable pressurizing member mounted in said housing for motion on a pressurizing stroke to provide pressurized air in said air chamber which is discharged through said air nozzle means to cause fluid material in said discharge region to be discharged through said fluid discharge nozzle means, and also for a return stroke;
- c. at least a portion of said fluid discharge section being arranged for forward and rear movement relative to said air pressurizing and supply section in a manner that said fluid discharge nozzle means moves toward and away from said air discharge nozzle means in a manner to control discharge of said fluid material through said fluid discharge nozzle means, each of said air pressure and supply section and at least said portion of said fluid discharge section being configured to be manually grasped so as to facilitate manually initiated movement toward and away from one another.
