PROCESS FOR HEATING THE SINGEING MEMBERS OF CYLINDER SINGEING MACHINES.
Application filed December 4, 1925, Serial No. 73,290, and in Germany December 10, 1924.
My invention has reference to improvements in the operation of machines for singeing textile fabrics and the like, and it is directed more particularly to a new and improved manner of heating the singeing member of such machines.
In the prior art the singeing member, generally in the form of a rotating hollow metal cylinder, is heated by means of a flame of gaseous fuel, such as illuminating gas. OW- ing to the relatively large amount of air in the gas-air mixture the active surface of the singeing cylinder is subject to rapid oxidation with resulting scale formation. Ob viously the detachment of such flakes or scales results in injury, such as scarring and pittin of the singeing surface, which is then the cause of irregular and more or less incomplete singeing action, so that the treated goods present an unfinished, uneven, marred appearance and, at that, have to be passed over the singeing cylinder more than once in the attempt to improve the final effect.
Furthermore, in the prior art the singeing member is heated from within, that is the active singeing surface is not brought into direct contact with the heating flame, which has its disadvantages from a mechanical point of view.
For the purpose of doing away with the indicated and other drawbacks I propose to heat the singeing member b means of a fuel of oleaginous character an cause the flame to directly impinge upon the outside or active face of the singeing member. I use for my purposes purified petroleum or paraffin, crude petroleum, gas oil, or suitable mixtures thereof. Tar oils could be used also, but have been found to yield a less favorable thermic output, since a relatively high per centage thereof isliberated in the form of carbon. Extended experiments and practical use show that the singeing surface, when impinged upon by such a flame, is kept coated with an exceedingly light film of oil which effectively prevents oxidation of the metal surface. This protective action, undoubtedly, is further aided by the deposition on the singeing surface of minute amounts of carbon.
The singeing member, which conventionally is of copper, remains always, also in glowing state, perfectly bright, untarnished and scale-free, so that its singeing action is even and complete all over its active surface with no injury or blemish to the goods from the insignificant yet effective oil and carbon deposit.
In order to make my invention more readily understood I will now describe it in y, detail in connection with the accompanying drawing which illustrates in its single flgure a more or less diagrammatic vertical section through a singeing device, as shown in my prior Patent No. 1,443,587, dated January 30, 1923, by which myimproved method of singeing may be carried out to advantage.
. The burner body 1, which extends the entire width of the goods to be treated, is enclosed in the housing 2 and is provided with two longitudinal chambers 3 and 4 for the introduction of the oil fuel and air, which flow into the central mixing chamber 5 and issue therefrom in upward direction through the longitudinal narrow slot 6 in the form of a sheet flame 7. Above the flame is rotatably jurnaled the conventional singeing member 8, which is impinged upon at its lower longitudinal zone by the flame as shown. ly passed over the upper zone of the member 8 by the guide rolls 10 and. 11. For the purpose of concentrating the flame heat on the singeing cylinder and also for use in preheating the burner, there are provided on the burner top the walls 12 and 13 of re fractory material, flanking the central sheet flame. Between the central burner proper and the housing 2 there is formed a jacket or chamber 14, open below as at 16, to receive the secondary air and at the top communicating with the space between the two flanking walls 12 and 13 through a plurality of apertures 15.
For carrying out the invention I mix the liquid fuel either with air alone, or additionally with a combustible gas, and then force this mixture out of the slot orifice 6 against the singeing member 8, after the latter and the flanking heat-concentrating plates 12 and 13 have previously been heated to red heat in any suitable, well known manner. Upon the oil-containing fuel flame encountering the preheated singeing surface there will immediately be deposited on the latter a delicate film of oil. This phenomenon is caused, undoutedly, by the fuel mixture, owing to the high temperature of the pro-heated glowing member 8 and the enclosing likewise glowing Walls 12 and 13, being disintegrated into pure gases, and it is The fabric 9 to be treated is guidedthese latter whi h re gnit d- The mi ratio between the oil vapors and the air must be so controlled that there is no danger of explosion and that the flame Will not be of sooting character.
To further assist complete, sootless combustion of the fuel mixture, I conduct secondary air into the space formed between burner top, flanking Wall plates and singeing member througha plurality of air passages 15, the oxidizing action of this sec ondary air being restricted to the flanking Walls '12 and 18, as the heated zone of the member 8 is effectively protected against such oxidizing action by the non-oxidizing flame 7 L What I claim is 1. The method of heating the singeing member in singeing machines, which "comcontaining a proportion of Qil DQ directly consumed While carried in the flame, pr0- jecting such flame directly upon the active surface of a traveling singeing member as to cause the oil carried thereby to be 59 tinuosuly deposited in the form of a film upon said surface, and continually evapgp V ating and consuming the oil thus deposited by the heatof the member and action" of the flame. i a
