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.

[ What is claimed is:] [1.] A paint colorant dispenser comprising:a) a piston movable in a longitudinal direction within a measuring cylinder;b) a stop assembly comprising:i) a longitudinally movable elongated stop member capable of being fixed in position relative to the measuring cylinder and located to limit a range of travel of the piston within the cylinder;ii) a gauge rod extending along and detachably affixed to the stop member, the gauge rod having a plurality of notches spaced apart along a first edge thereof; and,iii) a blade selectively engageable in a selected one of the notches; rein, when the blade is engaged in one of the notches, the stop member is held in a position such that a stroke of the piston in the measuring cylinder through the range limited by the stop member causes a desired amount of paint colorant to be dispensed.
