Pump for dispensing measured liquids in a consistent proportional amount

Abstract

A pump that dispenses measured liquids in a consistent proportional amount includes a plurality of cylinders, a plunger associated with each cylinder and a lever operatively connected to each plunger. Each of the cylinders is connected to a container having a chemical by an input tube. Each cylinder is also connected to a single outlet tube via a plurality of outlet tubes. The cylinders are sized and positioned to dispense a consistent proportional mixture regardless of the length of stroke of the handle.

What is claimed is: 
     
         1 . A pump comprising:
 a plurality of cylinders;   a plurality of plungers wherein one of the plurality of plungers extends into each of the plurality of cylinders;   a lever pivotally connected to the plungers;   wherein the cylinders are sized and positioned to dispense measured liquids in a consistent proportional amount based upon a length of stroke of the lever.   
     
     
         2 . The pump of  claim 1  further comprising a pair of check valves disposed within each of the plurality of cylinders. 
     
     
         3 . The pump of  claim 1  wherein the plurality of cylinders are disposed within a housing and the lever extends through a side wall in the housing. 
     
     
         4 . The pump of  claim 1  wherein the lever has one or more elongated members. 
     
     
         5 . The pump of  claim 1  wherein an input tube is connected to each of the plurality of cylinders at one end and to a container having a chemical at the opposite end. 
     
     
         6 . The pump of  claim 1  wherein an output tube is connected to each of the plurality of cylinders at one end and to a single output tube at the opposite end. 
     
     
         7 . The pump of  claim 6  wherein the single output tube is connected to a dispensing device.
