ABSTRACT:
A paint colorant dispenser has a notched gauge rod on a stop member. The notched gauge rod can be easily replaced to change the units of measure for the paint colorant dispenser and is also inexpensive to manufacture. A double notch at an extreme end of the gauge rod facilitates accurate metering of small quantities of paint colorant. The dispenser has a spool valve which includes a resilient sealing member which is biased against an inner surface of a valve bore by a strong spring. The sealing member provides a good seal and accommodates wear without leakage. With the exception of the spring, the valve may be made of plastic. The valve does not need to be manufactured to extremely precise tolerances. The paint colorant dispenser has a wiper assembly coupled to operate with the valve. The wiper assembly includes a resiliently mounted wiper which closes off a lower end of the nozzle except when the valve is set to dispense paint colorant through the nozzle.
