INsurrnniron.
Application filed February 18, 1924.-. Serial o. 693,716.
To @ZZ yiti/tom it may concern.'
i" it known that l, Fannnnrci; A. VL-insta a citizen of United States, residing at Columbus, in the county of ianldin and State of DOhio, have invented certain new and useful improvements in lns'uliiators, of which the following is a full, clear, and exact description.
ihis invention relates to insufilators, and has for its object to provide a device of this character which will spray or dust powders into the nose, etc., with an etciency equal to that with which liquids are sprayed by the ordinary atomi/zer.
ln spraying liquidsV the compression of the air bulb causes a partial vacuum in the upper end of lthe liquid-raising tube, and atmospheric pressure on the surface of the liquid ca'uses the liquid to be raised in the tube and it is then atomized by the air pressure. rllhis method cannot be followed in the use of powder for the reason that atmospheric pressure on the upper surface of the powder is insuflicient to discharge the latter, and a stronger pressure would tend to pack the powder and would fail to blow it out of the. nozzle in the desired manner.
To overcome the foregoing difiiculties, I have devised the present construction in which the air is conducted to a point'adjacent the nozzle and therefore acts only on a small portion of the powder at a time.
ln the drawings:
Figure l is a longitudinal section thro'ugh the insufi'lator.
Figure 2 is an end view of the air bulb, and
Figure 3 is a horizontal section taken on line 3--3 of Figure l.
Referring to the drawings more in detail, the numeral l indicates a drum or cylinder which may be made of glass or other similar material. Attached to the cylinder at one end thereof is a nozzle 2 which, in this particular instance is shown as curved although it may be of other designs to adapt it to particular purposes. The nozzle is shown as provided witha shoulder 3 against whichV an end of the drum 1. abuts, and this end of the dr'um or the nozzle may be roughened if desired in order to more securely connect these parts. Or, the nozzle may be formedY integral with the drum by drawing out the end of the latter.
Attached to the opposite end of the drum l isan air bulb al of rubber or the like which has formed thereon a stopper-like protuberance rllhe protuberance 5 is inserted in the end of the drum l and vthe latter may be tapered slightly as indicated by numeral G in order to form a seat therefor. The head of the stopper 5 is provided with an aperture 7 in which is positioned a glass tube or the like S. The tube S extendsvlongitudinally of the drum l to a point adjacent the wall of the nozzle 2 and is adapted to conduct air expelled from the b'ulb to a point adjacent the mouth of vthe nozzle. lt should be here noted that the position of the tube 8 within the bulb 4l may be varied so as to vary the space intervening; between the lower end of the tube and the wall of the nozzle, thus regulating the amount of powder dispensed at each operation of the instrument.
ln operation, it being desired to lill the drum' l with a powder, it is merely necessary to remove the nozzle 2, place the powder in the drum and return the nozzle to its position on the lower end of the drum. If it is now desired to spray the nose with the powder, the nozzle is placed in the nose, and the bulb 4 squeezed thereby forcing air through the t'ube 8 to a point adjaceut the mouth of the nozzle, thus forcing out a small portion of the powder from the lower part of the apparatus. The removal of pressure from the bulb will cause air to be again drawn into the same and may also draw some small part of the powder into the tube 8. This will not be objectionable, however, as any powder drawn into the tube 8 will be blown out when pressure is again applied to the bulb 4.
By this construction it will be apparent that I have devised an insuftlator consisting of relatively few parts and one which applies the spraying force at a point adjacent the nozzle mouth thus ejeeting the powder in substantially measured quantities. It will also be apparent from the foregoing description that the air is applied adjacent the bottom of the load of powder rather than at the top thereof, thus avoiding the tendency to pack the powder at the bottom of the instrument.. lVhile the device is described in connection with medicine in powdered form, it will be underill) stood that the same is equally Well adapted for use as a distributer for insecticides and the like.y
In accordance with the `patent statutes, I have described what I now believe to be the best embodiment of the invention, but I do not wish to be understood thereby as limiting myselfL or the scope of the invention, as lnany changes and inodiications may be made Without departing from the Spirit of the invention; all such I aimto include in the scope of the appended claims.
Having fully described the invention, what I claiin as new and desire to secure by Letters Patent is:
Y Y l. An insuHator including a drum, a nozslidably connected to said air bulb and terminating at a, point adjacent the mouth of the nozzle.
2. An insufllator including a drum, a curved nozzle on one end of the drum, an air bulb on the opposite end of the drum, and a tube Slidably connected to said air bulb and terminating at a point adj acent the outer convex Wall of the nozzle.
3. An insufllator including a drum, a nozzle on one end of the drum, an air bulb including a hollow, apertured protuberance seated in the opposite end of the drum, and a tube slidably mounted in the aperture of said protuberance and terminating at a point adjacent a Wall of the nozzle.
