    N° 280 A.D.1904 Date of Application, 5th Jan., 1(J(J4 Complete Specification Left, 4th Oct., 1904—Accepted, 10th Nov., 1904 PROVISIONAL SPECIFICATION. 10 16 20 30 An Improved Vaporizer or Fumigator, I, George Cup it Fowler, of 58 Louisville Road, Upper Tooting, in the County l London, Manufacturing Chemist, do hereby declare the nature of this inven- of tion to be as follows 6 The invention has for its object an improved vaporizer or fumigator which will effectually vaporize the liquid employed for fumigation without the risk of set¬ ting fire to or injuring such liquid when the latter has become thoroughly heated or is vaporizing. For this purpose I use an outer shell, preferably of metal, which has perfora¬ tions or openings as usual at the lower part to supply air to tfye lamp or burner in the interior thereof, and perforations or openings in the upper part with or without a crenulated top for the exit of the heated air and products of combus¬ tion. The top may be surmounted by a ring shaped deflector for further security. The shell may be simply placed over the lamp or burner, or it may have an opening, closable by a door, through which the lamp or burner is inserted. According to my invention, with a view to prevent the flame passing to and firing the vapor given off from the liquid or firing the contents of the container, I interpose between the lamp and the fluid container a diaphragm, which may be solid or may be made of perforated metal or wire gauze. When solid, it is preferably made of asbestos, and when using a solid diaphragm, outlet openings are formed in the body of the shell below such diaphragm in addition to open¬ ings above the latter. The diaphragm may be either fixed or removably mounted on or in the outer shell or it may be carried by the liquid container. The liquid container is preferably of such form as to cause the liquid therein to gravitate towards the centre, and it is preferably carried at a short distance 25 above the diaphragm. The outer shell may be made in two parts adjustable telescopically in order to permit of regulation of the heat transmitted to the fluid container. The invention is also applicable to the use of fumigating material sold in a solid form. Dated this 5th day of January, 1904, HARRIS & MILLS, 23 Southampton Buildings London* Agents.
