    A.D. 1900 N° 16,856 Date of Application, 21st Sept., 1900 Complete Specification Left, 19th June, 1901—Accepted, 20th July, 1901 PROVISIONAL SPECIFICATION. “ An Improved Appliance for Disinfecting by Means of Fumigation.” I, Charles Thomas Kingzett, F.I.C., of Elmstead Knoll, Cliislehurst, in the County of Kent, Chemical Manufacturer, do hereby declare the nature of this invention to be as follows: — My invention relates to an improved means of disinfecting bv fumigation and 5 consists in the use of an absorbent solid block such as a casting of plaster for taking up a quantity of volatile disinfectant powder or for soaking up a quantity of formic aldehyde solution or other volatile liquid disinfectant from which the said disinfectant is afterwards generated in the form of fumes or vapour by the use of a spirit lamp or other heating appliance and in connection therewith ot 10 the use of means by which a disinfectant liquid or water can be made to drip upon the said absorbent block with the object of increasing the supply of disin¬ fectant agent or of facilitating the generation of its fumes or vapour. In the case of formic aldehyde it is very difficult to expel the whole of this substance from its aqueous solution and the operation takes much time whereas 15 by employing such an appliance as is described in this specification the whole of it may be generated therefrom in the form of vapour in a much shorter space of time and the use of this appliance also enables the operator to produce aqueous vapour at the same time which is a distinct advantage as the aqueous vapour increases the volume and acts as a carrier of the disinfectant fumes and 20 brings them into intimate contact with the articles and things to be disinfected. As instances of solid disinfectants that may be employed in connection with such an appliance as is herein described, corrosive sublimate and paraformal¬ dehyde may be named, and as instances of liquid disinfectants that may be employed there may be named formicaldehyde in aqueous solution, “ Sanitas 25 oil, and liquid carbolic acid. The apparatus consists of a cage of metal, wire or gauze or the like having at its bottom a lamp above which is supported the block of absorbent material which is preferably contained in a metal tray or basin. Above the block is a vessel containing water or other liquid and provided with small holes wicks or 30 other appliances to allow the liquid to slowly drip onto the upper surface of the block. Dated this 20th day of September 1900. C. T.
