April 1956 w. ST. J. WILLIAMS DEVICE FOR DIFFUSING THE VAPOURS OF LIQUIDS Filed Jan. 5, 1951 Inventor 4-! 'hl'k WILLIAM ST JOHN WILLIAMS United States Patent O DEVICE FOR DIFFUSING THE VAPOURS F LIQUIDS William St. John Williams, Llaugefni, Anglesey, North Wales Application January 5, 1951, Serial No. 204,600
2 Claims. (Cl. 21-126) This invention relates to a simple, safe and reliable device or apparatus for expediting the dilfusion or dissemination, into the surrounding atmosphere, of vapours produced by the evaporation of liquids such for instance, as perfumes, disinfectants, or deodorisers, or produced from aromatic solids or crystals.
According to my invention, I provide a fanor impeller, preferably multi-bladed (hereinafter, for convenience of description usually designated fan), revolubly disposed within an open-ended ring or tunnel housing over which a perforate liquid absorbent covering, or a perforate carrier for solids, is, or may be applied, and said fan being adapted for actuation at required speed by a spring or other suitable source of power.
Where a liquid absorbent covering is used, a receptacle is provided for containing liquid to be evaporated and disseminated.
Preferably, said liquid container is in the form of a trough provided with a circular aperture around the margin whereof is an upstanding wall adapted to fit over the fans open ended housing. The absorbent material is placed so as to shroud the top of the wall and extend down the outside thereof into contact with the liquid and to be soaked therewith.
I will further describe my invention with the aid of the accompanying sheet of explanatory drawings, which illustrate, by Way of example only and not of limitation, one mode of embodying same.
In said drawings:
Fig. 1 is a part-sectional elevation of the apparatus disposed within an outer casing.
Fig. 2 is a plan view of the upper portion of the apparatus with the outer casing removed; and
Fig. 3 is a side elevation of the apparatus also with the outer casing removed.
a denotes a multi-bladed fan or impeller of sheet metal disposed within a circular tunnel-like housing b carried between a pair of side or check plates 0 which are secured together and spaced by transverse rod-like members c Said fan housing b is positioned in slots 0 provided in the cheek plates 0, and located by tongue-like members a cut in cheek plates 0 and screws 0 passing through housing b and engaging with tongues c Said fan a is mounted upon a spindle a the upper and lower ends whereof are revolubly located respectively in bearings b of said fan housing b, and a support bearing 6 secured to one of the cheek plates 0.
The lower portion of said fan spindle a is in the form of a worm gear and the spindle is rotated by a coil spring e of time-piece type at a high speed through the gear train f, g, h, j, k, l and m. Said spring is wound up by means of a key co-operating with the ratchet wheel n and a pawl 0 with leaf spring p. Fitted around said fan housing is a circular trough q having, at the margin of a central aperture formed therein, an up-standing flange or wall r. Covering the top of said Wall r and so that of fan housing b, and extending down the outside of the wall into trough q is a piece of fabric gauze s. Said apparatus is contained within an outer casing t provided with air inlets u and a removable dust cover v.
In use, dust cover v is removed, spring e is wound-up to cause the fan to rotate at the required speed, and the liquid to be evaporated is poured into trough q and by absorption soaks toward the middle of the fabric gauze whence, by the air impelled by the fan, it is evaporated and disseminated into the atmosphere.
It is to be understood that the liquid to be dealt with by my apparatus may be contained in any convenient manner other than as hereinbefore described and illustrated, as, for instance, a liquid receptacle may be formed around the exterior of easing t, the liquid being conducted to the fabric top s, say, by absorbent wicks.
Further, whilst the device as .illustrated is spring-operable and self-contained, said fan a may be actuated by any other convenient means, say, by a self-contained battery-driven electric motor, or by an electric motor driven by a remote source of power.
As will be clear, aromatic crystals or solids may be used in the device as described in place of liquid, these being preferably placed upon fabric top s above fan a. If, however, the device is intended for use exclusively with solids, the liquid container may be omitted and a Wire gauze carrier substituted for the liquid absorbent top .5.
What I claim is:
1. A self-contained portable device for disseminating vapors from liquid perfumes, disinfectants, and deodorisers, comprising a casing having a removable closure, a pair of spaced cheek plates, transverse rods disposed within said casing connecting said plates, a vertical tunnel housing carried by the upper portions of said check plates, a multi-bladed impeller revolubly mounted Within said tunnel housing, a spring motor mounted between said check plates, a gear train operatively connecting said motor to said impeller for rotating the same, a trough for liquid connected to and surrounding the upper part of said tunnel housing, and a loosely woven liquid absorbent fabric disposed over the upper end of said tunnel housing and extending downwardly into said trough for making all round contact with the liquid therein whereby the portion of said absorbent fabric extending over the upper end of said housing is continuously wetted by capillary action.
2. A self-contained portable device for disseminating vapors from liquid perfumes,, disinfectants, and deodorisers, comprising a casing having a removable closure, a pair of spaced cheek plates, transverse rods disposed within said casing connecting said plates, a vertical tunnel housing carried by the upper portions of said check plates, a multibladed impeller revolubly mounted within said tunnel housing, a spring motor mounted between said cheek plates, a gear train operatively connecting said motor to said impeller for rotating same, a circular trough mounted around said housing and having a central aperture, an up-standing flange provided on said trough at the margin of said aperture, and a loosely woven liquid absorbent fabric covering the top of said wall and extending down the outside of said wall into said trough.
