ApplicationMay 20', 1946,' SerialA No. 67130865 filaims.. 1
The present invention relates to a vapQr-lZer. More particularly, it relates to a vaporizer for inhalant material that usually is provided in.a.j.elly or salve-like form, which; vaporizer may conveniently be carried in the pocket, and-which has an igniter and flame supporting means readily operable so that the medicine may be vaporized` whenever it is needed.
This invention is an improvement upon copending application Serial No. 615,362, ledSeptember 10, 1945, by this inventor.
It is an object of thel present invention to provide a vaporizer of this type inK which the height of the flame may be easily adjusted. A particular object is to provide for the flame adjustment by an adjustable connection between a casing and a fuel cartridge barrel, providing for adjustment.
of a wick.
A further object ofI the invention.- isto provide ondary air to be available for the iiameV atthewick.
Further objects include the provisionof a. device of this kind that may be easily and inexpensively fabricated, and yet which will be durable and, de.- pendable in use.
Other objects will appear from the description to follow and from the drawings, inwhich:
Fig. 1 is an elevation of the device;
Fig. 2 is an elevation from the rightv side of Fig. 1;
Fig. 3 is a transverse section,taken on. the line 3-3 of Fig, 2; `and Fig. 4 is an extended View of the severalparts, showing the manner inY which they intert.
The device consists of an outer casing C that is generally tubular. It has a lower cylindrical part I with threads I I; and it has an upper flaring part l2 terminating in a, sleeve-like portion I'S. The upper part is provided with a suitable number of openings I4 which provide air to the wick, and also provide escape for combustion gases. The top part of Vthe lower section lil-is `also provided with additionall openings I5 to; provide air to the wick.
Immediately above the openings I5 and at the junction of the lower and upper sections I0 and I2 of the casing C, there is a ame baffle I8, in the form of a flanged disc that is permanently united to the casing C at the point indicated. The baffle I8 has a central opening I9. This central opening I9 receives the wick, as will appear.
The lower part ID of the casing C is adopted to receive an inner cartridge 22 that is generally tubular. The cartridge 22 has threads '23 that are designed to. inter-.operate with. the threads I,I.v on thelower casing section Ill. Bythis means, the cartridge- 22 may be adjustably located at agproper point within the lower. section, I0.
The Acartridge 22. hasasomewhat taperingupperl end wall 24., Vwhich.providesa center opening. 2,5,.to. receive and hold a Wick 2,6.. Thiswick. extendsv down into thecartridge 22 and is.. embedded. in-4 suitableliquidfuel holdingmeansll, such as 'cot-1. ton.
Whenv the cartridge 22.is insertedjntothe casing l0. and the threads.- engaged, a. closure cap 2S!4 may be irictionally slid over the projectingpart, of the cartridge '22;` and sealed, tightly therewith. Preferably, the cap 29, has a band. of; insulatingI material, such4 asplastic, around it. This furnishes a, mean to hold. the vaporizer evenl should, it b ecome hot.
The lower section Ill of the casing- C; at.. oneside supports a flint sleeve 3 2. Thisr sleeve, in turn, supports an abrasive wheel 3,3 at its top end. It. also contains a flint 'thatis urgedupwardly by a coil spring l under controlofaplunger 3,6,.withj a suitable handle thereon. In order to permitconf.
venient replacement of 1iin ts, va n4 opening 3 1'. isV
provided in the side of thesleeve 32,'. When the plunger 36 is drawn downwardlmianew flint may` be inserted intoplace.
The wheel 33 projects .through anopening 3!! in the side of the upper section and' is arranged. so that, when the wheelis turned; Vitv will deliver a spark to the wick.
The sleeve I3'- at the'top' ofthecasing' Q supports a pan 42 that preferably is. permanently attached into the casingalthoughrit may be. re,-
movable if desired; The pan Miisanged at 4 3:
to limit its downward movement in thesleevelike topv sectionA lf3 of thecasing, Itis adapted also to receive a closure capV 44' thatjtjs o verjit above the flange; 43.
In operation, the pani 4-2 will containa vapore* izahle medicine. This maybe in the form Qf a jelly or it may be supplied as a disereadilyin'- sertable into the pan 4:2: for being kept'in the pocket, the cap 44" will be disposed over the top of the pan 42, so that the material cannot escape therefrom. When it is desired to inhale fumes of the medicant, the cap 44 is removed. Then the wheel 33, which projects conveniently outside of the casing, is rotated to deliver a spark to the projecting part of the wick 26, which is, of course, supplied with suitable liquid fuel from the cartridge 22. This fuel ignites and thereby provides a flame on the bottom of the pan' 42 which causes the jelly or For storage, such'. .as i
the like to vaporize and supply fumes that may be inhaled.
The primary air for the wick is supplied through the openings I5. These openings can deliver fair to the wick owing to the fact that the -center part of the top wall of the cartridge 22 projects upwardly, as appears clearly in Fig. 3. Secondary air is provided through the openings I4, these openings also providing for the escape of the gases of combustion from the wick itself.
When it is desired to refuel the cartridge, it is necessary only to pull the lower cap 29 off of the cartridge and pour in the necessary amount of fuel.
It will also be understood that the refueling of the medicine pan 42 is equally easy. This may be done by filling the pan with medicine in any well known way, or the medicine may be supplied in cartridges that .fit readily into the pan 4Z.
One of the features of the present invention is the flame adjustment. It has been found that the amount of flame must be controllable in order to avoid the possibility, for example, of ignitingr the fumes of the medicine where the medicine consists of a combustible material. Also, it is desirable not to have excess flame because the same is awkward to handle :and is apt to burn the user. And too much flame produces excess heat- `ing of the device itself.
On the other hand, too little flame will not provide adequate vaporization or will operate too slowly.
The proper flame can be obtained in the present device by adjusting the amount of projection of the wick 25 through the port I9 of the flame baille plate IE. This adjustment is easily obtained by turning the cartridge 22 (or merely the lower cap 29), so that threads 23 in the cartridge nteroperating with the threads I I on the casing, move the wick upwardly or downwardly to dispose the wick 26 properly through the opening IS. As the wick is raised, the size of the flame is increased.
By the foregoing arrangement, which is obviously both inexpensive and durable, a proper flame may be provided. The danger of igniting the fumes is eliminated, and yet the vaporization may be obtained at desired speed.
It will be seen that this device accomplishes the objects set forth for it, and affords a con-l venient and satisfactory pocket type of vaporizer.
