    N° 5237 A.D. 1806 Date of Application, 9th Mar., 1896 Complete Specification Left, 9tli Dec., 1896— Accepted, 30th Jan., 1897 PROVISIONAL SPECIFICATION. An Improved Disinfecting* and Deodorising* Apparatus. I, Joseph Thomas Freestone, of 1 Kerfield Terrace, New Ferry in the County of Chester, Chemist, do hereby declare the nature of this invention to be as follows : — This invention relates to a disinfecting and deodorising apparatus in which the 5 disinfecting and deodorising is effected by slowly evaporating, by heat, a suitable liquid containing eucalyptus, terebene or the like, the object being to provide a simple and cheap apparatus in which an ordinary night light or fairy lamp may be used as a source of heat and in which the liquid to be evaporated is supplied continu¬ ously and automatically to an evaporating dish containing the disinfectant. 10 According to my invention I construct such apparatus as follows ;— The evaporating dish is carried by suitable supports some distance above the base of the apparatus w'bich is adapted to hold the night light or the fairy lamp, as the case may be, and the heat from the latter heats the evaporating dish and slowly evaporates the liquid therein. The liquid for replenishing the evaporating dish is 15 contained in a conical reservoir closed with the exception of an outlet at the apex thereof; the evaporating dish is about half filled with the liquid, and the conical reservoir is filled, then inverted and placed with the outlet in the liquid in the dish, the outlet being closed by means of the finger until it is below the level of the liquid in the dish. The reservoir is supported in this position, the outlet being of 20 course sealed by the liquid in the dish. The lamp is now lighted, and as the disinfectant liquid in the dish is evapor.iteil its level of course falls and as a result the outlet of the reservoir is unsealed, air is thus allowed to enter and a corre¬ sponding amount of disinfectant escapes and so replenishes the supply to the dish. In this way a slow but continuous evaporation is ensured and an effective and 25 economical distribution of the disinfectant results ; the night light or fairy lamp in addition to supplying heat serves its usual purpose as an illuminant, so that the apparatus is particularly useful in a sick room.
