    Nc 19,833 A.D. 1893 Date of Application, 21st Oct., 1893 Complete Specification Left, 21st July, 1894—Accepted 15th Sept., 1894 PROVISIONAL SPECIFICATION. Improvements in Ventilating* Apparatus. T, Fernand Diets, of 16 Rue Notre-Dame des Victoires, Paris, in the Republic of France, Jeweller, do hereby declare the nature of this invention to be as follows :— My invention relates to ventilating apparatus particularly applicable to ventilating 5 rooms and apartments, and the chief object of my invention is to ventilate without causing a draught, to purify the air entering by the ventilator, or to charge the air with scent or any antiseptic. In applying my improved ventilator to a window I propose to remove one pane of glass and fix the ventilator to the outside of the window frame, or it might be to 10 the inside. A convenient arrangement consists of a casing composed of two end frames preferably wider at the top than at the bottom and secured to the window frame one at each end of the opening from which the pane of glass has been removed. The end frames are about equal in depth to the opening and are connected by say a sheet of glass. 15 In order to admit air to the ventilator I cover the upper part of the casing with a sheet of glass or other suitable material held in a frame pivoted on brackets carried by the end frames near the window opening at one end, and at the other by adjustable rails carried also by the end frames and mounted in such manner that the back portion of the glass can be readily raised by means of the rails so as to 20 admit more or less air as required. In order to prevent impurities passing through the ventilator into the room I propose to employ a sheet of wire gauze or other suitable fabric which is stretched across the ventilator casing below the movable sheet of glass. If it be desired to scent the air admitted, or to charge it with an antiseptic, a 25 convenient plan is to fix below the gauze a perforated pipe extending from end to end of the ventilator casing and filling this writh sponge or other suitable material charged with scent etc., the perforated pipe being preferably made in two parts and hinged together for this purpose. This improved ventilator is readily cleaned, it offers but little obstruction to the 30 free admission of light, and when desired it can be applied in a similar manner to a door or other convenient opening into a room or building. Dated this 20th day of October 1893. H. B. BARLOW & GILLETT, Agents for Applicant. 35 COMPLETE SPECIFICATION. Improvements in Ventilating* Apparatus.
