Abstract
A mixing and dispensing apparatus for liquids that react chemically with each other from plural independent sources mixes same, and then cleans itself by injecting a terminal portion thereof into a mold. The mixing and dispensing means is intended to be incorporated into a system that provides measured quantities of the respective liquids, has control valving external of the mixing and dispensing means of the invention, and can recirculate the respective liquids except during actual mixing and dispensing. The mixing and dispensing apparatus has porting and passageways in its housing to permit recirculation and has a plunger which can be adjusted in its stroke to cover or uncover a certain amount of the mixing ports through which the respective liquids flow into the mixing chamber thence into the mold cavity. A stroke of the plunger sweeps the terminal portion of the reacting liquid mixture out of the mixing chamber, forcing it into a mold, thus cleaning the mixing chamber and packing the mixture in the mold cavity.
