    Gueniris Impts. in the Manufacture of Mustard and other blasters. I first wind tlie paper or other fabric (on which the mustard and other powder ’is to he applied) on a drum A, whence it is led beneath a roller B in a trough C, disposed beneath a reservoir D containing the adhesive solution, which is caused to discharge its contents on to the paper in the trough before it passes under roller B, the supply being 5 regulated by a cock E operated by a treadle E or otherwise. The reservoir D may however be dispensed with, as in Eigure 3, the adhesive solution being simply poured by hand on to the paper in the trough; in either case the roller B serves to spread the solution over the surface of the paper. On leaving the trough the paper sheet or fabric is passed 10 between two scrapers G- for reducing the adhesive substance thereon to a uniform thickness, and is then caused to travel beneath a hopper or case H, having a perforated or reticulated bottom through which the powder is sifted on to the paper, the hopper containing a supply of the mustard flour or other substance to be applied. This hopper H has a 15 vibratory or reciprocating motion imparted to it by two connecting rods I, I, each of which is pivoted at one end to the hopper H and at the other to a crank pin carried on a pinion J. These pinions J are keyed on the same shaft and are driven by the winch handle K through the train of gearing shown. The hopper H is supported and slides on 20 two parallel rods E, which pass through a sleeve bearing on the hopper* the rapidity with which the latter vibrates being regulated according to the thickness of the layer of powder required. M is an open frame¬ work of round iron, on which a number of wires are stretched lengthwise to serve as a support for the paper or fabric whilst receiving the powder, 25 and until it reaches the travelling creeper O, hereafter described. The mustard or other powder discharged from the hopper H falls on to the sheet of paper or other fabric A1 (shown in red lines), where it is retained by the adhesive solution previously applied, any powder in excess falling into a receptacle N placed below the wirework M, and forming a 30 framing on which the gearing and hopper H are mounted. The frame or receptacle N is fitted with doors N1, by which access may be had to the interior for removing the powder there accumulated. The paper is caused to travel from this point in the arrangement shown in Eigures 1 and 2, on an endless web O, beneath which travelling surface is disposed 35 a galvanized metal casing P, forming a table in which steam is intro¬ duced by pipes P1 for drying the solution on the paper with the deposit of mustard. Other pipes Q are provided for the exit of the steam and
