    Sarrower Sf Stuarfs Improved Spray Froducer. And under one modification this Invention or its features of novelty, particularly and essentially consists in constructing the steam generator in the form of a vertical hollow internal and external ‘‘ walled ’’ conical vessel of a double, tubular, or annular form in horizontal section and triangular in radial vertical section, by having the lower part of its outer 5 case cylindrical, either attached to or formed by the upper part of the ordinary hollow vertical cylinder forming the main portable case con¬ taining the usual spirit or other lamp passed in through a door or lateral opening in the side near the flat bottom on which the lamp rests and the whole stands, and having the handle secm^ed to and projecting out 10 laterally from the lower part of this case, where there is little or no heat, for the greater convenience and comfort of lifting and carrying the apparatus in its operation and use. This improved construction of the steam vessel set concentrically over the lamp besides being stronger gives a much longer and greater heating surface to the internal conical 15 tube forming the actual heating surface and funnel of the vessel, and the outer crown being also conical gives greater elegance, strength, and height to the vessel, besides giving a longer, narrow, or tubular water space all round the lower and greater part of the heating surface, and gives a greater height and capacity of steam space at the top of the 20 vessel or boiler above the water inlet, exposed also to a small part of the direct heating surface of the top so as to insure pure steam slightly dried or superheated passing off at the very top, where the branch pipe is formed for inserting and jointing the hack end of the steam tube of the actuating nozzle through which the jet of steam acts, which are 25 as short as possible to prevent condensation therein, which improve¬ ments taken together enables this apparatus to he set to work sooner after applying the lamp with less waste of heat, and prevents ‘‘priming or the blowing out of hot water through the steam tube and nozzle, and is a great security to its proper working without trouble or management, 30 and safety against hmming the person using the apparatus over those heretofore in use. The steam tube and nozzle being set by preference in a horizontal position, while that of the liquid nozzle attached to it at right angles descends vertically from it into the phial or other small vessel containing the medicinal or other liquid desired to he made into 35 fine spray or vapour placed at the side of the main case within a small sheath or case attached near the upper part thereof for its reception, and inserted therein by preference from the under side of the sheath so as to go up over the liquid tube through the open mouth, or a hole
