Abstract
An improved spray apparatus designed to optimize the pattern of the texture material and the performance of the spray apparatus to look and perform similar to a hopper texture gun or texture spray rig used by professionals. The spray apparatus, has a housing defining a cavity. A transfer wheel is rotatably mounted to the housing, the transfer wheel having a hub defining a hub axis, and a plurality of transfer flaps. A propeller is rotatably mounted to the housing and positioned above the transfer wheel, the propeller having a spindle and a plurality of fins. A firing pin is attached to the housing above the propeller. An actuator is mounted to the housing to cause the propeller to rotate. A gate may be provided to control the flow of the material to the transfer wheel.
Claims26
A spray apparatus, comprising:
- a) a housing defining a cavity, wherein the housing comprises a lower section, an upper section, and a middle section therebetween, wherein the housing defines an opening into the cavity at the upper section;
- b) a transfer wheel rotatably mounted to the housing inside the cavity, the transfer wheel comprising a hub defining a hub axis, wherein the transfer wheel comprises a plurality of transfer flaps;
- c) a propeller rotatably mounted to the housing and positioned above the transfer wheel and inside the cavity, the propeller comprising a spindle and a plurality of fins;
- d) a firing pin attached to the housing above the propeller;
- and
- e) an actuator mounted to the housing to cause the propeller to rotate.

- c) a propeller rotatably mounted to the housing and positioned above the transfer wheel, the propeller comprising a spindle and a plurality of fins;
- d) a firing pin attached to the housing above the propeller;
- and
- e) an actuator mounted to the housing to cause the propeller to rotate, wherein the transfer wheel, the propeller, and the firing pin are positioned relative to each other such that actuation of the actuator causes the propeller to rotate in a first direction, rotation of the propeller causes a first fin to abut against the transfer wheel, the abutment of the first fin against the transfer wheel causing the transfer wheel to rotate in a second direction opposite the first direction, while a second fin abuts against the firing pin causing the second fin to bend in the second direction until further rotation causes the second fin to abruptly spring back in the first direction.
