An opening 27 is provided in the side wall of the In the form of the inVentOn ShOWIl in Fig- 1 housing l0 in position to register with the open is illustrated a lamp arranged t0 be pled 1113011 end 23 of the tube 21 and the body of substance a table or the like and constructed so as to procontaining `the volatile perfume or deodorant is 105 vide both direct and indirect lighting. For this adapted to be inserted through the opening 27 purpose, the housing or shade 10 is opaque and and into the open end `230i the tube. may be made of sheet metal or the like and the For .this purpose a vial 28 may be provided for upper open end thereof is flared or bell-shape, containing the volatile substance. The vial may l as shown at 11. contain cellulose or other 4suitable nbrous mate- 10 rial, impregnated with the volatile perfume or deodorant, as shown at 29. The tube 21 may be provided near its other end with an indentation as shown at 3G to act as a stop to limit the position of the vial therein and the vial may be retained in position by means of the cover plate 31 which ts over the opening 27 and is held in position as by the spring catch 32, a washer 33 of rubber or the like being preferably provided upon the inner side of the cover plate to engage the `closed end of the vial 28.
An opening 34 is provided in the upper wall oi the tube 21 adjacent to the open end of the vial 28 and a valve may be provided in this end portion oi the tube. This valve may be substantially cupshape as indicated at 35 and of such size that it has a turning iit within the tube 21. One side or" the open end portion of the valve may be bent inward or reduced as at 36 so that when the same is turned to the position shown in Figs. 1 and 4, the opening 34 in the upper wall of the tube is uncovered.
t will be seen that by rotating the valve until this reduced portion 36 thereof is moved away from the opening 34, the straight or cylindric portion of the cup-shaped valve will register with the opening 34 entirely closing the same.
An opening 37 is formed in the end wall or the cup-shaped valve 35 and is arranged to register with a similar opening 38 in the adjacent side wall of the housing 10 when the valve is in the open position as shown in Figs. l and 4. The knob 39 is provided with a reduced portion journaled through the sidewall of the housing 10 and iixed to the end wall of the valve 35 so that by rotating said knob the valve may be turned to open or closed position.
It will be seen that the light from the incandescent bulb 12 will be directed upward through the `upper open end of the shade or housing 10, producing an indirect lighting and if it is desired -to provide direct lighting, transparent or trans lucent panels of any desired size, shape or design, as indicated generally at 40, may be provided in suitable openings 41 which may be formed in the side walls of the housing l0 for that purpose. If desired, the shade or housing 10 may be formed of glass or other transparent or translucent material.
As shown in Figs. 2 and 3, the improved deo'dorizing lamp may be in the form o1n a floor lamp, in which case the shade or housing indicated generally at l0 may be supported upon a pedestal adapted to stand upon the floor.
This pedestal may comprise a-spacing sleeve or tube 43 located between the housing or shade 10 and the base indicated generally at 44, the
. upper end of said tube surrounding the depending reduced neck 45 formed at the lower end of `the housing 10', and abutting the shoulder'v46 upon the housing at the upper end of said neck, while the lower end of the tube surrounds the reduced* upwardly extending neck 47 upon the base 44 and abuts the shoulder 48 at the lower end of said neck.
A tie rod 49 is located within the tube 43, the lower end of the tie rod extending through a. central opening 50 in` the base 44 and being provided with a nut 51 while the upper end of the rod extends through a conical' block 52 located within the tapered throat 53 of the housing, a nut 54 being mounted thereon for tightly Vclamping the housing 10 and base 44 together` upon the spacing tube 43. l
cated within the upper portion of the shade or' housing 10 and mounted within a socket 13 supportedwithin the central annular iianged portion 14 of th cup-shaped bracket 15 which may be connected to the inner walls of the housing by any suitable and well known manner such as spot welding or the like, and which is provided with one or more openings 15 in order to provide for a passage of air upward through the housing 10.
The electric cord 17 of usual construction may be connected to the socket 13 and extended through an opening 18 in the lower portion of the housing 10 and is provided at its end with an attaching plug i9 as in usual practice, for connection to a suitable base receptacle or the like. The socket 13' may be of the form usually provided with a chain pull switch and the chain 20' thereof may be located through an opening 20 in the side of the housing 10 and provided with a knob or button 20 for manipulating the switch.
The body of substance containing ythe volatile perfume or deodorant may be located at anyr point within the housing in a direct route of air to or from the source of heat, and for the purpose of illustration the same is shown as .located below the incandescent .bulb 12' and so arranged that it may be in a direct route of air thereto.
The tube 21 may be located within the lower portion of the housing 10', one end thereof butting tightly against the adjacent inner wall of the housing as at 22, the other open end thereof being preferably spaced from the opposite wall or the housingv as indicated at 23.
This tube may be secured in position within the housing by means of the ears 22" formed at the end 22 of the tube and spot welded or otherwise attached to the adjacent inner wall of the housing 10.
An opening 27 may be provided in the side wall of the housinglO in position to register with the open end 23 of the tube, and thev body of substance containing the volatile perfume ordeyodorant may be inserted through the lopening 27 and into the open end 23 of the tube.v
A vial 28 may be provided kfor this purpose and may contain cellulose or other suitable fibrous material` impregnated with the volatile perfume or deodorant as indicated at 29.
An rindentation 30 may be formed near the other end of the tube to act as a sto-p to limit the position of the vial within the tube and the vial may be retained in position by means of the .'1'30 cover plate 31 which iits over the. openingv 27 and is held in position as by the spring catch 32. The upper wall of the tube is provided with yan opening 34 adjacent to the open end of the vial and a valve may be provided in this end portion of the tube similar to the valve 35. shown in Figs. 1 and 4. This vaive is indicated generally at 35', being substantially cup-shaped as above described and of suchsize that it has a turning fit within the tube 21. One side of the y k scribed. The incandescent light'bulb 12 may be lo- From ine above it win be evident that'the light from the incandescent bulb 12 will be directed upward through the upper open end of the shade or housing, producing, an indirect lighting effect. It should be understood that a direct lighting effect may be produced in this floor lamp type of the invention in the same manner as illustrated and described with reference to the form of the invention shown in Fig. 1.
The operation or" both forms of the invention is the same. With the valve open, air enters through the opening in the side wall of the housing, passing through the cup-shaped valve and against or in contact with the body of substance containing the volatile perfume or deodorant and is then drawn upward through the opening in the top of the tube 21 or 21', as the case may be, and through the upper portion oi the housing or shade and out of the upper open end thereof, the heat from the incandescent bulb causing a continual circulation of air, cold air being drawn in at the lower end of the housing Where it picks up the odor of the volatile perfume or deodorant and then rises through the housing or shade as it becomes heated.
Although the invention has been illustrated and described as an odorizing lamp for the purpose of furnishing light and at the .Garne time vaporizing a perfume or deodorant, it should be understood that the invention may also be used simply as a vaporizer with any other form oi electric resistance than an incandescent bulb, and instead of vaporizing a perfume or deodorant, the housing may contain a volatile insecticide such as is used for destroying moth and other insects.
