Abstract: A texture sprayer comprises an air compressor, a motor, a spray gun, an airflow switch, and a pressure switch. The air compressor is disposed to send the pressurized gas down a pneumatic line, and is driven by the motor. The spray gun receives pressurized gas from the pneumatic line, and expels the gas when actuated. The airflow and pressure switches are both disposed on the pneumatic line. The airflow switch is situated between the spray gun and the air reservoir, and powers the motor when gas flows through the airflow switch. The pressure switch powers the motor whenever pressure within the pneumatic line falls below a threshold value.

Abstract: A motor assembly includes a shaft, an electric motor operatively connected to the shaft to drive the shaft in a first rotational direction, a clutch assembly connected to the shaft, and a fan connected to the clutch assembly and configured to supply the electric motor with cooling air. The clutch assembly drives the fan when the electric motor drives the shaft and allows the fan to freewheel in the first rotational direction when the electric motor is not driving the shaft. A method of operating a fan cooled electric motor includes energizing the electric motor to drive a shaft in a first rotational direction using the electric motor and de-energizing the electric motor so that it no longer drives the shaft, allowing the fan to freewheel in the first rotational direction.

Abstract: The striper has a solid direct drive axle 12 powered either by chain, belt, gears, hydraulics, etc. 14. Two wheels 16 are attached to a solid axle 12 by means of adjustable friction devices 18 that transfer torque—stacked hardened thrust washers 20 with spring washers 22 to maintain a constant drive torque with ability to have limited slip at a specific load range. The spring washers 22 allow consistent load over long periods of wear. When each tire 24 is properly loaded “equally” the striper 26 will have natural ability to travel in a straight forward motion over bumpy surfaces specifically grass (turf), not common with standard type differentials that power only the least resistant wheel 16. When cornering the inside wheel 16 will slip as necessary based on the turning radius. When the wheels 16 are overloaded, wheels will slip, preventing damage to the drive mechanism (transmission) 28.
