    N 6823 A.D. 1897 Date of Application, 16th Mar., 1897 Complete Specification Left, 15th Dec., 1897—Accepted, 12th Mar., 1898 PROVISIONAL SPECIFICATION. A New and Improved Disinfecting and Antiseptic Block. We, James Laing Mortimer and Joirx Hubert Williams, both of 45a, Dale Street, Liverpool, Diysalters, do hereby declare the nature of this invention to be as follows: — A combination or mixture of permanganate of potash or permanganate of soda with naphthaline, camphor ^ na])hthaline, camj)hor or soap & the object is to sur¬ round each crystal or particle of the so<la or potash with a material that is slightly soluble in water or of a volatile nature, so that as the material evaporates or is dissolved, the potash or soda will become exposed & subjected to the action of any liquid passing over it disinfecting same automatically. In forming the blocks we heat the permanganate of potash or soda with the naphthaline, or camphor naphthaline or camphor to Fahr. and thoroughly mix them, this mixture is then transferred to moulds of the size & shape rec^uiied, the materials may be used in any proportions but we find a suitable proj>ortion for general purposes to be 75 parts of the potash or soda to 25 parts of any of the 15 other ingredients. In making the soap combination we mix the potash or soda with soap when the latter is in a liquid state, or if we use a milled soap when in a powder A mould to the required size & shape. The blocks may be made any size or shape to suit the particular trap, drain, 20 sink, flush pipe, chamber or cistern, for which they may be required. We claim that this method of using permanganate of potash or ]>ermanganate of soda is much more economical than using them alone in the form of crystals or powder; a sufficient quantity is given off only when the drain or flush is used. After first fixing in position a continuous & regular supply of a disinfectant 25 & antiseptic will be ensured for a considerable time without further attention. Dated Fifteenth day of March 1897.
