Specification of Letters Patent.

Patented N (W. 2, 1920.

Application filed November 7, 1918, Serial No. 261,483. Renewed May 17, 1920. Serial No. 3822003 Be it known that I, FRED G. lVI-iiin, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, 4500 Wabash avenue, have invented certain new and useful Improvements in. Diffusers; and I do declare the fol lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to a diffuser for impregnating air with a suitable disinfectant perfume or the like and it is particu larly adapted for use in theaters, auditoriums and similar places of amusement.

One of the objects of the invention is to provide an inexpensive, efiicient means for diffusing a liquid in the form of a vapor so as to impregnate the air for the purpose of disinfecting the same. As disinfectants are ordinarily objectionable on account of their offensive odors I have provided means whereby the materials to be diffused may be interchanged. For example, first the disinfectant or germicide may be utilized and the objectionable odor counteracted by a suitable perfume.

In the drawings Figure I is a perspective view of a device constructed in accordance with my invention and applied to an ordinary electric fan. Fig. II is a detail view, partially in elevation and partially in sec tions showing the construction of the device detached, Fig. III is an enlarged view of the end of the diffuser tube; Fig. IV is an end view of one of the clamps to attach the device to a fan; Fig. V is a side view of the clamp; Fig. VI is an edge view of the clamp and Fig. VII is a detail view of one of the wick-carrying members.

Referring now to the drawings by numerals of reference,

1 designates an ordinary fan provided with the usual shield 2 having a central disk 3 concentric with the fan shaft. 4: designates an elon ated tube, open at its respective ends but adapted to be closed by the caps 5 and 6 which carry the wick supporting devices 7. The wicksupporting devices as shown in detail in Fig. 7 each comprises a wire bent intermediate its ends as at 8 and 9 to prbvide with retaining fingers and the free end of the wire is bent to a semi-loop as at 10 and provided with a downwardly projecting finger 11 to assist the fingers 8 and 9 in retaining the wick 12 in position to absorb the liquid germicide or disinfectant. The wires 7 are preferably riveted to their caps 5 or 6 as the case may be and each cap is provided with a down wardly struck finger 13 to engage a slit 14. in the top of the tube which is provided with openings 15 serving as nozzles through which the germicide or disinfectant may be evaporated. Between the ends of the tube 4: an upstanding inlet port 16 adapted to receive a tubular nozzle 17 on the metal screw cap 18 of the liquid container 19 which holds the disinfectant or germicide or perfume, as the case may be.

In order to secure the device to the disk 3 of the fan guard I provide the slidable clamps 20 and 21; each clamp consists of a plate 22 having a central opening 23 and flanges 24c and 25, in the latter of which is a screw 26. When the clamps are slid on the tube 4: so that the lips or flanges 24: will ongage the inner surface of the disk 3, the disk will be clamped between said flanges and the tube 4:. The tube cannot turn in the openings 23 because the tube is substantially elliptical in cross section and engages the substantially elliptical openings 23.

l/Vhen the device is secured in place with the container 19 filled or partially filled with the desired liquid, for example, the germicide, the wicks will absorb the liquid to such a degree that liability of the liquid leaking out through the openings 15 will be avoided. The fan is set in motion and blows a draft over the openings 15 so that the air will be come impregnated with the material carried by the wicks which have been supplied by the contents of 19. If a germicide is first used and it is desired to overcome the obj eotionable odors by perfume the container 19 will be removed and a substitute container applied; it being understood, however, that the caps 5 and 6 with their wick supports have been previously removed and other wicks substituted to absorb the perfume; or if desired, the caps and wick supports can be removed so that new wicks may be substituted for those previously contained.

It will be apparent that the air of a comparatively large theater or auditorium may be sufliciently impregnated with the desired liquid in a comparatively short time," due to the continuous draft over the openings 15.

What I claim and desire to secure by Letters-Patent is:

1-. In a device of the class described, a tube,

removable caps on the ends of said tube, meanso'n-thecaps for engaging slots in the tube, wick containers carried by said caps adjacent to openings in said tube and a fluid receiving nozzle carried by the tube.

2. In a device of the class described, a tube having a notched end, a removable cap'on the end of the tube provided with a downwardly projecting finger for engaging the notch in said tube, a longitudinally extending wick support fixed with respect tothecap 'and'having intermediate fingers to be engaged by wick strands running parallel with said support.

3. In a diffuser of the class described, a

vertical tube to receive an inverted receptacle, oppositely extending right angularly disposed tubular members communicating with the Vertical tube and having openings alongthe top edges thereof, removable caps engaging said tubular members and having depending fingers to engage slots in the tube in line with the openings, and wick supports carried by thecap.

L'In a difiuser of the class described, a horizontal tube having openings in the top thereof and a longitudinal slot adjacent to one open end, a removable cap to close said endrhaving a depending finger for engagement with theslot, and a wire wick support rigid with thecap and having upwardly and downwardly extending fingers to be engaged by a wick strand, said wire wick support being insertible in the tube.

In testimony whereof I aflix my signature.
