    Provisional Specification. Gamgee 8f Maitland's Impts. in Medicating Cotton and other Fibres. sulpho-carbolates, permanganate of potash and charcoal as disinfectants, antiseptics, or deodorizers, according to their respective natures, or with solutions of opium, morphia, hydrate of chloral or other narcotics and sedatives, in order to obtain wadding, felt, cloths, or wool charged with these medicinal agents for surgical or sanitary purposes, 5 The manner in which it is preferred to impregnate the cotton or other fibre with these medicinal agents is as follows :—When the agent employed is a liquid, the lap of fibre from a carding engine is made to pass through a trough in which the liquid is contained. The fibre after having become saturated in the trough is conducted between a pair of 10 squeezing rollers by which the excess of liquid is forced out, and it will be found convenient to have these rollers adjustable, so that the pressure put upon the lap may be regulated according to the quantity of liquid it is required to leave in the fibre, The lap then passes qn to the drying cloth, after which it is recarded. If the liquid employed is. an acid, or 15 one which will act upon and break the fibre, the recarded lap is placed in layers between outer layers of long fibre, impregnated or not. When the agent employed is in the state of powder, such as. charcoal, it will be found convenient to sprinkle it upon the lap by means of a dredger or similar device attached to the carding engine, and then to submit the 20 fibre to pressure in order that the whole body of the fibre may become impregnated with the powder. The fibre thus impregnated may be enclosed between layers of unimpregnated fibre.
