    _ . in and relating to Devices for Distributing Odors, Disinfectants^. i evolving of the fan and prevent the same from being thrown around the room and upon the table or other fan support. When a detachable band is used the same must be adjustable so as to fit the stationary guard of the different makes c 0± ±ans and to accomplish this I provide a longitudinally disposed slot, 20, in ° on^ 0 , *ne ^an(i into which the screw, 21, which is carried by the other end of the band fits. A thumb nut, 22, is threaded on the screw, 21, and forms means for securing the two ends of the band together in their adjusted position, n opeiation, as the fan is caused to revolve the liquid in the reservoir, 1, will i iv ^ agitated by centrifugal force and will pass through the small opening in the diaphragm, 10, carried by the inner ends of the tubes, 3, into the central opening, o, of each tube. The sponge, 9, prevents the said liquid from feeding too freely through the tube. The liquid then passes through the tubes and out thiough the small openings 6, and is caught by the pads, 8, which become thoroughly saturated with the odorous liquid and as the said liquid evaporates lo the blast created by the revolving fan blades will distribute the odors throughout the room. Any drippings which might escape from the pads, 8, will be caught by the felt guard, 19, and the odors arising from this guard as it becomes saturated will also be distributed throughout the room in the same manner so that none of the material used is lost. 29 In lig. T of the drawings the atomizing tubes are shown as curved at their free ends and the ends of the tubes are tapered or flattened out for the purpose of partially closing or reducing the opening at this end of the said tube so that a very fine spray will escape when the device is in operation. The interior of the tubes of this construction are provided with wicks 23, which 25 extend from the ends of the tubes to the reservoir, 1, The' wicks may simply enter the reservoir or they may be curled around inside the said reservoir so as to become thoroughly saturated with the odorous liquid. In the construction shown in Fig. 8 the rear face of the reservoir, 1, is made in the form of an inverted cone, the purpose of this being to allow of the 30 device being centered against the end of the fan shaft when being applied to the fan. In Figs. 6 and 7 the tubes are shown in such a proportion as to extend out to a point near the ends of the blades, this being the point of greatest agitation in fan motors. In Fig. 7 I have shown a modified form of securing means for the reservoir 35 consisting of the flexible wires, 24, which are held to the reservoir by means of the straps, 25, the said wires being twisted around the fan blades thereby holding the reservoir securely in position. My invention can also be applied to ceiling fans by securing the reservoir, 1, directly to the fan blade at a point near the central pivot and having one 40 tube, such as 3 exending from the reservoir to a point near the free end of the fan blades. I have found my device to be very useful in the sick-room for dis¬ tributing medicated vapors and especially advantageous in hospitals for this purpose. It has also received great favor for ordinary household and office use in furnishing a pleasing perfume to the atmosphere. 45 Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is : — 1. In a device for distributing odors the combination of a closed reservoir adapted to hold the odorous liquid, openings provided in the periphery of said 50 reservoir, atomizing tubes threaded into said openings and a cap or bag com¬ posed of absorbent material secured over the discharge ends of the atomizing tube for the purpose described. 2. In a device for distributing odors, the combination of a revolving reservoir adapted to be carried by the shaft of a rotary fan, hollow tubes threaded into 55 openings provided in the periphery of the said reservoir, a perforated diaphragm secured over the inner end of the tube, a filling of absorbent material provided
