Device for discharging a mixture of two liquids

A device for replenishing an animal dipping tank comprising, in combination, a dipping tank, a rocker mounted astride the dipping tank, a pan mounted to the rocker comprising compartments movable by the rocker from a first position to receive a first fluid to a second position to discharge said first fluid, a conductor positioned above the pan to deliver said first fluid into the compartments at their first positions, said conductor being positioned transversely of the pan at mid-length thereof, said movement being effected by the successive filling of said two compartments and being such as to empty at least partially the compartment which has just been filled and means for delivering a second fluid into the respective compartments, the operation of which is timed to deliver the second fluid into the compartment into which the first fluid is being delivered while the mixed first and second fluids are being discharged from the other compartment, comprising pump means positioned adjacent one side of the pan, said pump means including a piston and piston rods protruding from the opposite ends thereof and stops, said pump means being mounted to the pan so as to be moved in consonance with the pivotal movement of the pan about the pivot axis thereof and said stops being so located that pivotal movement of the pump means engages the piston rods with the stops and wherein engagement of the piston rods with the stops operates to actuate the pump means to alternately deliver a predetermined quantity of the second fluid to the respective chambers.
