10 Claims. (01. 219-45) 1.- to be supported thereby and so as to utilize the radiant heat thereof in aid of the operative vaporizing and disseminating processes.

This invention has for an object to provide a vapor emanator of the kind and for the purposes mentioned comprising, a chambered member of annular form provided with vapor vents, said member being charged with a vaporizable agent or substance capable of emanating vapors or fumes of desired character, together with means for operatively relating said member in attached supported relation to an electric light bulb in such manner that warm air in the vicinity of the lighted bulb is so controlled as to be caused to move in ascending streams adjacent to the vapor vents to thereby assure a rapid and eflicient dissemination and diffusion to the surrounding atmosphere of the vapors or fumes emitted from said vents.

The invention has for another object to provide a vapor emanator characterized as above stated, wherein the body of the annular chambered member constituting the same is provided with air admission means to receive, for passage through the body interior, a portion of the warm air in the vicinity of the lighted bulb to which the body is applied, whereby not only is the vaporizing of the contained agent or substance assisted and hastenedbut the emission of the resultant vapors and fumes is also expedited.

Other objects of this invention, not at this time more particularly enumerated, will be understood from the following detailed description of the same.

Illustrative embodiments of this invention are shown in the accompanying drawings, in which:

Fig. 1 is an elevational view of one form of the novel vapor emanator according to this invention as operatively applied to an upstanding electric light bulb; Fig. 2 is a similar view showing the emanator operatively applied to a pendant electric light bulb; Fig. 3 is a top plan view of the emanator per se; Fig. 4 is a bottom plan view of the same; and Fig. 5 is a vertical cross-sectional view of the same, drawn on a somewhat enlarged scale.

Fig. 6 is a vertical cross-sectional view of a somewhat modified form of. the novel vapor emanator operatively applied to an upstanding electric light bulb; and Fig. '7 is a bottom plan View of this emanator per se.

Fig. 8 is a vertical cross-sectional view of another modified form of the novel vapor emanator operatively applied to a pendant electric light bulb.

Fig. 9 is a top plan View, and Fig. 10 is a vertical cross-sectional view of still another modified form of the novel vapor emanator.

Similar characters of reference are employed in the hereinabove described views, to indicate corresponding parts.

Referring to Figs. 1 to 5 of the drawings, one embodiment of the vapor emanator according to this invention, as therein shown, comprises an annular bottom section I I of U-shape or other selected cross-sectional shape, the same providing an interior chamber l2 open at its top side. Cooperative with the open top side of said bottom section II is a top section or cover [3, preferably adapted to telescope thereover to close the open top of said interior chamber 12. Said top section or cover I3 is preferably of upwardly arched cross-sectional shape, and formed therein, between the annular central axis thereof and its inner margin or periphery is an annular row of spaced perforations which serve as vapor vents l4 leading outwardly from the interior chamber 1 2, and, by reason of their described disposition, directed inwardly toward the surface of an electric light bulb B when applied in operative assembled and supported relation to the latter.

Formed in connection with the inner wall of said bottom section II, adjacent to the upper margin thereof, are a plurality of outwardly pressed hollow bosses or ribs I5 open toward the interior chamber 12. Said bosses or ribs 15 are thus circumferentially spaced around the inner side emanator, so as to provide intervening gaps or passageways H5. The under sides of said bosses or ribs I5 are placed to provide air intake openings H, in such manner that the upper sides of said bosses or ribs overhang these openings so as to provide deflector sections l8 which deflect or turn upwardly moving air into the interior chamber l2 of the emanator.

The bottom of said interior chamber l2 provides a basin l9 within which is deposited an agent or substance 20 of suitable character capable, when evaporated, to emit vapors or fumes for desired effects of deodorization, disinfection or perfuming of the surrounding air into which they are emitted and disseminated.

The agent or substance 20 may be furnished in any suitable form, 1. e. of either liquid, solid, powdered, or pastry form. For example, a volatile substance'capable of yielding vapors or fumes, adapted to permeate the atmosphere for a desired eifect, may be mixed with or incorporated in paratfin, a low melting point solid, so that when the latter is cool and solidified, said substance is imprisoned therein with tendency to suppress evaporation thereof when functional operation of the emanator is not desired; but, when heat is applied sufficient to melt the-parafiin, said substance will be liberated and readily evaporated. Such combination of low melting point carrier and a selected volatilev active substance has the advantage that, when cool and solidified, it will not spill, and consequently the emanator charged with the same can be more conveniently handled both during commercial distribution and by the ultimate user. While such combination is perhaps preferred for the reasons given, I do not limit myself solely thereto, since so far as the novel structure of the emanator as a container is concerned, it is indiiferent to the particular form or kind of volatile substance employed, or to the condition of said substance used either alone or in combination with a suitable carrier or vehicle. I

The internal diameter of the annular emanator device is somewhat less than the maximum external diameter of an electric light bulb B with which it is to be operatively associated. The emanator device is provided with resilient retainer member which may be utilized to hold the device against displacement. when applied upon the top end portion of an electric light bulb B disposed in an upstanding position. In a preferred form and arrangement thereof, said retainer members comprise a pair of circular loop members 2| made of. spring wire, the same being respectively anchored or afiixed to diametrically opposite points at the exterior underside of the bottom section II, and so as to fold flatly against the latter when not in use (see Fig. 4). When desired to be used, the free sides of the loop members 2| are flexed to turn the same downward so as to permit the bulb B to pass upward therebetween until the emanator device seats itself on the bulb top, whereupon, when said loop members 2| are released the same spring inwardly toward and around the bulb sides so as to grip the bulb, and thus anchor the emanator device thereon (see Fig. 1). If the emanator device is applied to a pendant bulb, the retainer loop members 2| need not be used, but remain folded against the underside of the bottom section thereof (see Fig. 2). I

.When the emanator. device is adapted to the electric light bulb B, the bosses or ribs l5 con tact the bulb sides so as to space the inner wall of the bottom section therefrom. Inasmuch as there are gaps l6 between adjacent bosses or ribs l5, free or open air passageways are provided intermediate the emanator device and the bulb. When the bulb is lit, the air surrounding the same will be heated by heat radiated from the bulb, and being lighter will naturally tend to rise,

izab-le content, so that the desired vapors or fumes are liberated. By reason of the provision seminated in the surrounding atmosphere.

of the air intake openings I1 formed in the undersides of the ribs or bosses i5, and which cooperate with the overhanging deflector sections IB, a proportion of the rising heated air will be caused to enter the interior chamber I 2 of the emanator device, and by its movement and pressure therein will not only assist in the vaporizing efi'ects upon the substance 20, but will set up a circulation or draught through the interior chamber I 2 which will efficiently carry the liberated vapors or fumes outwardly through the vents M to join the rising air streams flowing upwardly through the passageways l6 and thus to be carried quickly away from the bulb and dis- It will be noted that the vents M are so located at the. sloping inner area of the top section or cover l3 that the vapors or fumes emitted therethrough are directed definitely toward the rising air streams so as to be readily mingled therewith and carried away thereby.

' In Figs. 6, 7 and 8 there is shown a somewhat modified construction of the novel emanator device according to this invention, the same comprising an annular bottom section 30 of suitable cross-sectional shape and provided with a closing top section or cover 3| having vapor or fume vents 32 leading from the interior chamber 33. Pressed out from the inner walls of said bottom section are ribs or bosses 34 to engage the sides of a bulb B to which the device is operatively applied, and so as to produce intermediate passages for the upward flow of air as above referred to. The means to introduce a portion of ascending air into and for circulation through the chamber 33 and its vents 32, is of somewhat different form, and comprises tubular ducts 35 affixed to the bottom of the section 30 to extend upwardly through the interior thereof and its content ofvaporizable substance 20 to the space above the level of the latter, thus conducting warm air, the heat of which may be radiated from the duct walls directly to the substance 20, while at the same time the circulation of the currents of air through the interior aids in carrying members 36 may be aflixed to the emanator del vice, as shown in Figs. 6 and '7, in place of the resilient loop members previously described.

In Figs. 9 and 10 there is shown a simpler form of the emanator device of this invention, which, however, still embodies certain of the novel principles of this invention. In this simple form thereof, the device comprises an integral annular body 40 suitably shaped to provide a trough-like bottom section M and inner and

outer top sections

42 and 43, so formed and related that the free marginal portion of the outer section 43 is spaced from and somewhat overhangs the free marginal portion of the inner section 42, thus providing an annular inwardly described vent mouth 44 which is directed toward the sides of a bulb to which the device is applied in use. Pressed out from the inner side of the body 40' are circumferentially spaced ribs or bosses 45 providing intermediate air passages 46 to serve the purposes already above described.

In all of the above described constructions, the projectional extent of the bulb contacting ribs or bosses may be selected or predetermined so as to dispose the body of the emanator nearer to or farther from the sides of the bulb according to the desire to increase or diminish the effects of heat. radiated from the bulb in aid of evaporation of the content of the device. Ordinarily the closer the emanator body is disposed relative to the bulb, the greater the effective heat and more rapid the evaporation, but if the emanator body is further removed from the bulb sides, the less effective is the heat and the slower the evaporation.

It may also be pointed out that order to assist in stabilizing the attached relation of the emanator device to the bulb, the bulb contacting ribs or bosses of the former may be coated with a tacky more or less adhesive substance, such e, g. as latex, rubber or other suitable gum, which will afford a non-slipping contact with the glass of the bulb.

Although the invention has been described in detail, it is not to be limited to the exact construction as shown, since variations may be made within the spirit of this invention and the scope of the here following claims.
