The Myers Power Spray Pump 



With patent Automatic Pressure Governor, has all the desirable features found in any 

 Spray Pump, viz., vertical cylinders, renewable brass valves and seats, 

 large stuffing boxes fitted with brass glands and followers, large air 

 chamber, machine cut gears, ample crankshaft and connecting rod 

 bearings, etc. In addition it is fitted with a patented Automatic 

 Pressure Governor which eliminates the trouble-causing relief valve, 

 and briefly, has the following advantages 

 over the ordinary construction. Safety — 

 Pressure relief is not dependent on the oper- 

 ation of a sluggish or defective relief valve. 

 Uniform pressure regulation — The governing 

 mechanism is not exposed to the clogging or 

 corrosive action of the spray liquid which 

 always effects the operations of the relief 

 valve. Elimination of unnecessary wear — 

 Plungers and valves are in action only when 

 spray material is passing through the nozzles. 



Fig. 1739 



In operation the Automatic Pressure Governor has for its object the positive control of the 

 pump pressure. This is accomplished by a simple arrangement of a combined lever and 

 spring on each plunger connecting rod. [See A and B, Fig. 1739] which, when the pressure 

 reaches a predetermined limit, automatically stops the operation of the plungers without 

 interrupting the driving power, and again permits them to resume operation when the 

 pressure falls below this limit; also removes the entire load on engine causing it to run 

 idle [saves gasoline]. All wearing parts thoroughly lubricated.
