    Guenirfs Impts. in the Manufacture of Mustard and other Plasters. sheets (this being the only kind suitable for the purpose) previously masticated by passing between toothed rollers in a closed apparatus, and digest it at a temperature of from 80 to 90 degrees Fahrenheit in about 5 or 6 lbs. of benzine having a density of about 17 oz. per pint. This 5 operation is continued for twenty-four hours, after which I introduce the mass into a tinned metal apparatus provided with a stirrer similar to a churn, and well agitate the contents, simultaneously with which I add in small quantities at a time about 15 lbs. of essence of petroleum. After this has been done I pass the viscous liquid obtained through a 10 wire sieve when it is ready for immediate use, as it loses its glutinous properties by keeping, and becomes unsuited for producing the adhesion of the mustard flour. Various light hydrocarburets obtained by the distillation of schists and other matters with lime and oils of naptha may also be substituted for the essence of petroleum before referred to. 15 Blisters and other medicative plasters may also be similarly prepared by the aid of the rubber solution without affecting in the least the pro¬ perties of the powders made use of. I also prepare a mild kind of sinapism in the following manner for children and delicate or nervous persons:—I take 40 parts of white mustard flour, 40 parts of black 20 mustard bran reduced to a fine powder (both being deprived of their oil), and 20 parts of black mustard flour, the whole being well mixed. I then prepare the plasters therewith in sheets in the manner herein-after described. It will be understood that I do not limit myself to the precise proportions of the above ingredients, as they may be varied to 25 suit the degree of strength desired. When prepared in the proportions indicated the plaster will have a slow progressive action requiring about twenty minutes to attain its maximum effect. It will be also understood that instead of using bran or white mustard I may introduce into the mixture an inert powder, such as linseed, for example, but with less 30 advantage, I will now describe the machinery for the manufacture of mustard and other plasters according to this Invention.
