Lab sample jet dyeing machine

In a jet dyeing machine for treating textile material in generally rope form with a treating liquid which includes means defining a closed vessel providing an endless path for circulation of a length of the textile material through treating liquid held in said vessel;

• means in said path for forming a jet-like flow of the treating liquid and for directing such liquid flow against the textile material so that such flow at least assists in circulating the textile material around said path;
• means for withdrawing treating liquid from said vessel means and supplying treating liquid under pressure to said means for forming said jet-like flow wherein the improvement comprises an adjustable means for forming the jet-like flow of treating liquid including a hollow jacket member secured to said machine and having top, bottom and sidewalls each of which is provided with means defining an opening extending therethrough in at least a portion of their respective wall areas;
• first and second nozzle assemblies, said first nozzle assembly extending within said jacket member and being removably secured within the opening in the top wall of said jacket member;
• said second nozzle assembly extending within said jacket member and being slidably retained within the opening in the bottom wall of said jacket member, so that said first and second nozzles are aligned and spaced from one another with the portions extending into said jacket member having inwardly and downwardly tapered inner ends, defining an orifice therebetween and wherein said flow means is connected to the opening in said sidewall so that treating liquid will flow through said jacket member, and moving means for incrementally moving said second nozzle assembly with respect to said first nozzle assembly so as to define a variable orifice therebetween through which treating liquid is directed toward the textile material.

• a first nozzle assembly removably secured in one side of the hollow jacket member;
• a second nozzle assembly slidably secured in the opposite side of said hollow jacket member;
• said first and second nozzle assemblies each having portions thereof extending into said hollow jacket assembly with each having inwardly and downwardly tapered inner ends which are spaced from one another so as to define an orifice therebetween and means for incrementally moving said second nozzle assembly for incrementally varying the size of the orifice.
