[Communicated from abroad by the Firm of Kocn & IIeller, of Avenue du Mail, 15, Geneva, in the Republic of Switzerland, Manufacturers.] Improvements in Apparatus for Facilitating the Inhalation of Medicinal Vapours. I, Henry Harris Lake, of the Firm of Haseltine, Lake & Co., Patent Agents, 45, Southampton Buildings, in the County of Middlesex, do hereby declare the nature of this invention to be as follows ; — The invention consists of an inhaling apparatus constructed so as to be used 5 either for inhaling hot filtrated air or dry or wet vapours of any suitable medicinal product or both. The base of the apparatus consists of two portions which are intended to contain a reserve of medicinal products to be used witli the. apparatus. The said base carries a cylindrical casing having a laterally extending portion and containing 10 an alcohol-lamp. The cylindrical casing is provided with openings and carries the boiler tiaversed by the stove which is provided with a cover which latter when shut causes the lamp to be extinguished. The boiler is provided with a double wall forming an air-gap around the inner portion which contains the water to be vaporised. 15 The inner portion is provided with a safety-valve. The steam produced in the said inner portion is used either in the left portion of the apparatus or in the right one or in both at the same time if two persons use the apparatus at once. The left portion of the apparatus consists of a cock connected by one tube to the inner portion of the boiler, by a second tube to the water bag or receptacle and by a 20 third tube to the infusing vessel. If water is to be filled into the boiler the water receptacle is first withdrawn and the second tube then allows the water to escape and to indicate that the same has reached the desired level in the boiler. In the infusing vessel there are provided two sieves intended to carry material 25 to be fused and prevent it falling down into the cock. The top of the infusing vessel carries a removable horizontal tube to which is affixed an adjustable) carrier which supports a glass-tube and a drop-cup. If steam is produced in the boiler and if the cock is open, the said steam is caused to traverse the material contained in the infusing apparatus and to escape 30 from the removable tube through the glass-tube into the mouth of the person using the apparatus. The right-hand portion of the apparatus is constructed as follows: The air-gap of the boiler is connected by means of a tube to an air-filter in which a suitable sterilizing material is contained. The said tube and filter are placed 35 in line with the tube connecting the air gap with the chamber or laterally extend- [.Price Sd.]
