Regulator for Oil-Gas BurnersPatent No. 1,253,578, issued to Charles E. Crane ofSeattle, Washington, shows a regulator for oil-gas regulator consists of a mixing chamber having a verticalcentrally disposed intake tube and a cylindrical outer and spaced from the outer wall is a perforatedcylindrical wall which forms the burner, and this burnerextends above the cylindrical outer wall. Secured to the outerwall is a dome-shaped cap which deflects the oil downwardly. into the mixing chamber, after it enters through the oil is sprayed through the tube from a nozzle and thetube is formed telescopically, so that the distance betweenthe upper end thereof and the cap can be adjusted, to varythe amount of air entering the mixing chamber with the oilspray. Hydraulic ValvePatent No. 1,253,013, issued to William A. Doble of SanFrancisco, California, and assigned to the Pelton Water WheelCompany of San Francisco, discloses a novel form of needlevalve for controlling the flow of water. Much difficulty hasbeen experienced in valves of this nature due to the intensevibration of the valve when it is moved to a position adjacentthe valve seat. The flow of water past the valve pro-
