EDWARD BITTER, OF NEW YORK, N. Y.

ELECTRIC VAPORIZER.

Application filed December 3, 1924.- Serial No. 753,664. b

ToaZZ whom it may concern: Be it known that I, EDWARD BITTER, a citizen of the United States, residing at New York city, borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvements in Electric Vaporizers, of which the following is a specification.

This invention relates to incense or perfume dispensers and more particularly to devices of that-nature which operate in conjunction with a heating unit..

Among the objects of this invention is to provide an incense or other perfume or fluid dispenser which is mounted adjacent to a heating unit so that the rate of evaporation.

of the fluid is greatly increased, said dispenser comprising a casing for fixing the rate of evaporation.

Another object of this invention is to provide a device fordispensing any'fluid in the form of a vapor or a gas, said device comprising for this purpose a heating unit for evaporating the fluid, and a casing for envelopi ng said fluid and said heating unit to conserve theheat for the sake ofeconomical and eflicient operation.

Another object of this invention is to provide a gas or vapor dispenser in connection wlth a lamp COIIIPIISHlg means for containing a fluid, and a casing to support said fluid container in movable relation so as to permit said casing and said lamp to be mounted in upright or in downwardl directed position while the fluid containing means is always upright position to cor tain the fluid. 1

Still another object of this invention is to "provide in connection with a lamp. or the like, a fluid dispenser to utilize the'heat thereof for purposes of evaporation or g'asification, said dispenser comprising heat enveloping means comprising a plurality of "parts having novel engagementwith each otherand with the container "for the fluid. Wi-th the foregoing and other objects in view the invention-consists in the arrangement and combination of parts hereinafterdescribed and claimed and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had'to the accompanying drawings in which like,

reference characters designate the same parts in the several views, and in which Figure 1 is an elevational cross-section of the device looking in the direction of line 11 of Fig. 2;

Fig. 2 is an external view of the device. Fig. 3 is a-sectional view of the device mounted in a difi'erent position, parts thereof being broken away.

Fig. 4 is a sectional view on the line H of Fi 1.

Refbrring now more specifically to the drawings, I show the fluid dispenser comprisinga heating unit, such as a lamp 10 or the like which is operative preferably by electricity, supplied through a suitable plug connection such as a standard base or plug 11. Mounted adjacent to the lamp is a fluid container 12 which is cons ructed preferably of an annular form so a to receive a portion of the lamp body within the in ner' walls 13 thereof. A heat envelopingmeans, such as a casing 14 is used to coverboth the lamp and the fluid containing means so as to control the circulation of air about said containing means, thereby conserving the heat of said lamp, andcontrolling the. rate of evaporation .of the fluidf Said heat enveloping means comprises preferably an extension of neck 15 at an end of which the standard plug 11 is formed, as about the annular portion or shoulder 16'to which the threaded metallic thimble 17 is secured by means such as cement 18. The circuit for the lamp is made in'the usual manner through wires 19 and 20 having contact respectively with said thimble and with a center contact 21 which is supported by suitable insulation 22. Mounted along said neck is a means spaced from the plug aforesaid and having electrical engagement with said plug and said lamp for supplying current to the latter. This takes preferably the formof a socket 23 for receiving the base or plug 24 of the lamp, said socket being secured to a porcelain base 25 as by means of screws 26 having engagement with the lugs 27 of said socket. A central spring contact 28 is also provided to complete the circuit therethrough and through the screw 29 which supports the same in the usual manner. This socket arrangement is mounted in an suitable manner, thoughv it is cemented in place by cement placed within ferring again to the plug 11 i casing as shown,

the clearance between the base and the wall of the neck. As a means for insulating said socket arrangement from direct contact with the hot gases within the casing 14, insulation such as a plate or disk of mica 30 is provided which is preferably threaded upon said socket, and is of somewhat larger diameter than the neck 15 so as to abut against the converging sides of said casing as shown at 31, thus making an effective gas seal. Re-

onnection with the socket 23, it will be seen that my invention comprehends the principle of arran ing in conjunction with a heating unit sue i as an electric lamp and means for providing a relatively static and high temperature heat zone about the lamp, of a plurality of connectors such as a plug and socket which are in electrical circuit, one of them such as the plug having connection with a line circuit or the like, while the other has connection with said lamp for supplying current thereto, said plug and socket being spaced from each other whereby the former is positioned more remotely from said heating unit to be less affected by the heat thereof. This arrangement also permits of the ready insertion or removal of a lamp, and, as specifically disclosed, provides a neat and inexpensive construction and one which is highly adapted for the uses to which this invention can be put.

The fluid container 12 is mounted in a suitable manner within the heat and evaporation controlling means 14, and preferably upon a casing part or device having detachable engagement with said means. More specifically, said device takes the form preferably of a covert-32 which is provided with lugs 23 formed along anofl'setextension or shoulder 34 so as to lie within a rib 35 or the like, said lugs having suitable engagement with said rlb, as by means of a spring follower arrangement 36, to bear upon said rib and retain said cover in engagement with the casing 14. Said follower arrangement comprises preferably a spring pressed face or screw which has slidable engagement with a head 37 of a screw 38, whereby it is secured to said lug. While the rib 35 is extended entirely along the free edge of said ceive said follower. Whenthe cover is detached from said casing, the pressure, upon the follower screw caused by abutment of the flange 40 of's aidoffset extension against the edge of the rib being released, the spring elongates, moving the follower screw outwardly of the head 37. Therefore to permit of proper engagement of said followerwith said rib, abevel-or cam face 41 is formed thereon at said slot, thereby permitting said follower to ride 11 on to the dwell 42. Since in the preferre arrangement, I

. provide a pair of supports or followers, the

it is slotted as at 39 to relowers when the same abut thereon. While 7 the. fluid container can be made of any suitable material, it is preferably formed of metal so as to absorb more readily the heat of the lamp. But such construction permits the same to be mounted upon the screws 38 as by being sprung therebetween. hfore over, the container can likewise be readily removed in the same manner, thereby permitting the lamp to operate for the sole pur pose of giving light, and consequently at a lower temperature. It will be seen therefore that the cover 32 is readily engaged or disengaged from said container as by means of a rotational movement, and that a resilient engagement is provided which takes care of expansion resulting from changes in the temperature of the glass. Moreover, said cover provides in conjunctionwith said casing a more uniform and accurate means for controlling the character or temperature of the heat zone about said lamp and the rate of evaporation of the fluid from the container 12. This result is effected by providing for a passageway for the hot gases through the device which takes the form preferably of a plurality of openings 44 -within' said casing and openings 45 co-operating therewijh within said cover. As the rate of evaporation depends not only upon the temperature within said casing, but also upon the pressure and the humidity of the I filled with fluid by holding said cover in the position shown in Fig. 1 and then inverting the same for,mounting u on the casing, the lamp passing through t e inner wall 13 of said container as before. The specific arrangement of said container relatively to the heating unit is such as to be retained in substantiallythe same relation to the heating unit, as to the filament of the lamp, whether the dispenser is used in the upward or downward position, thereby insuring a uniform operation or evaporation of the fluid in the two positions.

The construction lends itself directly for ornamental or aasthetic purposes as well as the utilitarian functions set forth above. Thus the outer globe or shell may be made to simulate a rose or other attractive object. Also it will be obvious that since the liquid container may be snapped into or out of place in the cap or cover, it may be removed readily when the. device is to be employed for lighting purposes.
