2"Claim's.

My invention relates to atomizers for'peri'umes and similar fluids.

The primary object -of -my invention is to provide an atomizer which is simple and easy to operate, and which can be made inexpensively and from a few parts, -all of which may be produced by the screw machine process and without bending or soldering.

A further object :of the invention is to provide an atomizer in which the fluid supply chamber is shut off when the device is not in use, and in which operation of the device automatically establishes communication with such chamber.

A further object of the invention is to provide a mechanism of this type in which a novel and extremely eicient arrangement for breaking up the stream of perfume into a spray or mist, or in other words for really atomizing the perfume, is provided.

Further objects and advantages of the invention will appear amore fully from the following description, particularly when taken iin conjunction with the accompanying drawing which forms a part thereof.

In the drawing:

Fig. 1 is a side elevation of an atomizer embodying my invention, with the top removed.

Fig, 2 is a vertical cross section.

Figs. 3 and 4 are Vcross sections on the lines 3-3 and 4-4 respectively of Fig. 2.

Fig. 5 is an enlarged perspective View of `the atomizing member. g

As shown in Fig. 2, the atomizing mechanism comprises a body portion or casing 2 having a chamber 4 therein Yfor receiving the perfume or other fluid Ato be atomized. This vcasing is provided in its top with an .opening 5 in which may be threaded a piston member vBxl'iaving a downwardly extending portion I6 which fills and closes the opening 6. A washer I2 of rubber or other suitable material may be placed between the bottom of the piston member 8 and the top wall of casing 2 in order to seal the joint therebetween.

Below the extension l!) piston member 8 has a further extension I4 of smaller diameter, also externally threaded, and smaller than aperture 6. On this member Id. is threadedly secured a tube I6, the lower portion of which is iirst tapered inwardly as at I8 and then has a smaller downwardly extending portion 2D which extends almost to the bottom of chamber 4. Within the tapering portion I8 is a ball 22 acting as a valve for which the tapering portion I8 forms the seat, and above this ball is a perforated retaining disc 24 suitably arranged to prevent the escape of the ball and `to ac t as a support for the spring to be described below.

The upper centralportio'n 26 of the :member 8 acts as a piston, and `outside of this portion is 4'5 an annular groove 28 and an annular outer wall or guide wall 38, integral with piston portion 26. Vertically slidable in'the annular groove .28 is a cylinder member 32, which iits -tightly within the groove and forms with piston member :8 a 10 space 34 cooperating as a cylinder with the piston portion 26. The top of the cylinder space 34 is closed by a wall 36, which is preferably rounded on top to provide a suitable smooth surface for operation by the finger of the user. T5

Piston member 8 is provided with a vertical central passage 38 through which extends a rod 40 slightly smaller in diameter than passage 38, and threaded at its upper end in the top wall 36 of cylinder 32. The lower end of rod 40 ex- 20 tends through tube or pipe I6, and is provided near the top of that tube with an annular flange 42 of greater diameter than passage 38. v.A coil spring 43 is arranged in vtube il'li, resting .at one end on plate 24 and at the other lend engaging "25 flange 42. The diameter `.of flange 42 is somewhat less than the inside diameter of 'tube I6, or in any event is so arranged that fluid may pass upwardly through .the tube, and also through passage 38, without interference from "3b flange 42 except when the saine is in its raised position against the bottom of member "8.

From the .cylinder 34, iiuid .may escape through passage 44 into recess l46. Recess y46 extends out to one side of top wall 36, :and with- 35 in the recess is arranged a nozzle member 48 having a nozzle opening 50 ofv reduced .size to permit the escape of V'atomized uid. The member 48 has a tube-like portion 52 extending with'- in tlie Ibore 46, and within portion `52 and the -40 bore is arranged a helix 54 (Fig. 5) which substantially lls the borre, and which consists of a plug or rod, of substantially the same diameter as extension 52, and provided with a pair of helical grooves in its surface. By this construc- 45 tion, the fluid passing through the bore is forced to follow the configuration of the helix. This imparts a swirling motion to the fluid and causes it to be atomized or broken up into a ne mist as it leaves the nozzle aperture 50.

The atomizer may be closed and covered when not in use by a cap or cover 56, which may be threadedly secured on the base or reservoir 2.

'Ihe operation of the device is very simple. The wall 32 iits very closely Within the groove 28, 55

so that the connection is substantially air-tight, or at least suiciently so for the operation of the device. If the cylinder member 32 is depressed with the finger, ball 22 will be in its lowered position and the air in the cylinder space 34 will be forced out through nozzle 48. When the pressure on the top 36 is released, the cylinder member 32 will rise suddenly and will create a reduction in pressure in the space 34 which cannot be immediately relieved through opening 50. This will cause some of the perfume to be raised up through tube 20 and past one-way ball valve 22 into the section I6. As this operation is repeated, the section I6 will gradually be filled and then perfume will be finally brought up intoy the chamber 34. Of course in continued operation thereafter each use of the atomizer will 'draw in more of the fluid and will thereby replace in the chamber 34 perfume which may have been removed therefrom.

AsA soon as the perfume is present in chamber 34, depression of member 36 will cause the perfume to be ejected through helix 54 and nozzle 50 in a fine spray. This perfume then escapes from the device in atomized condition as is desired.

Each time the member 36 rises under the action of spring 43, the flange 42 will be pressed against the bottom of the piston member 8 and thereby will close the lower end of passage 38. This will seal within the container all perfume below this level and will prevent losses by evaporation of any large quantities even though the device may stand for some time without use.

In order to ll the atomizer, the piston member 8 may be unscrewed as a whole, and the fluid poured through opening 6 into the reservoir.

Member 3 may then be replaced.
