LAMBERSON'S ANNUAL SEED CATALOG, 1902. 71. Fie:. 1187, "Kerowater" Spray Pump, is designed for mechanically mixing and spraying kerosene and wa- ter or crude petroleum and water. The oil and water are so thoroughly mixed and blended that the discharge from the nozzle is a milk-like emulsion. Either 5, 10, 15, 20, or 25 per cent oil can be used. Construction is simple. As shown by cut a galvanized iron tank, containing oil, goes inside of a barrel, contain- ing water. Inside of oil tank is a small pump, and out- side of oil tank is another pump, similar in design, but larger. Both pumps are operated by one common lever, and while one draws oil from the oil tank, the other draws water from the surrounding barrel. They both discharge at a common point, where the water and oil are blended. Percentage of oil is varied by changing a pin in the head of lever, which shortens or lengthens the stroke of oil pump. Pump is a positive measuring device and de- livers exact percentages of oil. Outfit is readily removed from harrel. Oil tank and pump can be removed and the water pump used for general spraying with Bordeaux Mixture, etc. Price with barrel $ With two mounted 10-foot lead s 4-ply hose and softzle $ Fig. 1187.
