1. An adjustable gas nozzle comprising, in combination:

  • a nozzle body member having an elongated passageway therethrough with an inlet opening at a first end and an outlet at a second end;

    a conduit connected to the nozzle body member;

    an adjustment member disposed intermediate the conduit and the nozzle body member and having a first restricted orifice;

    a coupling between said conduit and said body member to permit first and second alternative positions therebetween;

    a by-pass passageway around the adjusting member and said first restricted orifice;

    cooperative surfaces in said first position to seal between said body member and said adjusting member to close off flow through said by-pass passageway to permit a first gas flow through the two outlets in series so that gas flow rate is regulated by said first restricted orifice;

    cooperating means associated with said adjusting member and said conduit upstream of said cooperating surfaces for limiting the displacement of said nozzle body member relative to said conduit in said first position;

    said nozzle body member being moveable into said second position relative to said conduit to relieve the seal between the said body member and said adjusting member to permit a second gas flow of an amount greater than said first gas flow through the combination of said first restricted orifice and said by-pass passageway; and

    a seal provided between said conduit and said nozzle body member to preclude leakage of gas therebetween, said seal comprising integral surfaces on said nozzle body member and said conduit.
