1 Claim. (Cl. 299-95) This invention relates to improvements in atominers, particularly those applicable for use with perfumes or toilet waters.

Broadly it is an object of this invention to the supply port through spring and diaphragm media; the port being opened upon displacement oi' the valve to permit pressure discharge in atomized form of the liquid, the spring and diaphragm media being adapted to return the valve to initial position for sealing the port upon-re-l lease of the valve displacing mechanism.

Still further, it is an object of this invention to provide, in an atomizer of the character described, spring and diaphragm elements for maintaining the valve oi the atomiser in seated condition with respect to a supply port, the diaphragm complementing the spring for returning the valve to seated condition, while at the same time serving as a seal for the chamber leading' from the port to the discharge aperture o! the atomizer.

These and other advantages, capabilities, and features of the invention will appear from the subjoined detailed description or one specic embodiment thereof illustrated in the accompanying drawing, in which Figure 1 is a front elevation, partly in section, of the atomizer control in closed position.

Figure 2 is a front elevation, partly in section, of the open control.

Figure 3 is a plane view in section, taken along lines 3-3 of Figure 1.

Referring to the reference characters in the drawing, numeral I0 represents ,the hase of the atomizer in the iorm of a container, herein shown of glass, though the same may be of metallic or non-metallic substance. The control mechanism II is carried on plug I2 from which extends syphon tube I3, leading interiorly of the base, the said plug I2 being carried on the wall I4 forming the neck of the base, there being disposed between the shoulder I5 of the plug and I6 of the base, gasket I1, of rubber or like material, the plug being locked to the base by means of cap I8, interiorly threaded to acton the exterior threads of the neckof the base, as at I8, said cap Il having aninwardly extending rim 20 pressing against the annular rim 2i of the plug to form a firm lock between the plug and the base.

Within the plug I2 is formed a reduced bore or port 22 leading to delivery chamber 23, in 5 which there is formed cup formation 24, leading to bore or discharge port- 25,- directed substantially at right .anglesto bore 23. A seat 26, of substantially annular form and projecting slightly above the base oi'- chamber 23 surrounding the l0 bore 22.

Within the side wall of plug I2 there is formed a threaded aperture 21, in which is disposed screen of iine mesh 28 and nipple 29, the screen being maintained in aperture 21 against the wall 1l of the bore 2l, by contact with the inner peripheral edge o! the nipple thereagalnst. The nipple 29 has bore 30 of gradually 'decreasing diameter leading to a substantial pin point BI at its extremity, to provide the necessary atomizing 20 nozzle.

Within wall '32 of the plug I2 there is carried the valve control mechanism II for the atomizer; said valve control mechanism comprising a head 3l having an exterior threading cooperating with 25 the interior threading of the plug I2 as at 3 4, and having an annular rim resting on the upper shoulder of wall 32 of the plug I2 to seal the same.

Within the head there is positioned a valve stem 30 38, the base of which comprises two interlocking sections, 31 and 38, the latter of which has rmly ilxed therein valve 39 formed of rubber or like material, and having a flat base 40 resting against seat 26 surrounding bore or port 22, and having 35 a'teat 4| of diameter substantially to rest in bore or port 22. This :dat formation 40 resting against the seat 26 and the teat 4I resting within bore 22, due to the resilient nature of the valve 39, forms a double seal for the supply outlet at 40 port 22.

Between interlocking sections 31 and 38 there is disposed an annular diaphragm 44 formed, in this instance, of rubber, said annular diaphragm being locked between said sections at its inner 45 periphery, and being maintained rigidly therebetween upon intermeshing of the threaded formation 45 of these members. The outer periphery of the diaphragm rests between rim 46 of the plug and shoulder 41 of the head, and is rigidly main- 60 tained in such position insofar as its outer periphery is concerned, through intermeshing of the threaded sections of said head and plug.

Mounted on valve stem 36 between the shoulder 48 ot interlocking section 31, and inwardly ex- 55 tending annular groove Il oi' the head ll, there is disposed compression spring Il, normally maintaining the valve stem and the valve structure carried thereby in position on seat oi' the plug, for sealing the port 22. The valve stem Il, as shown in Figure 3, is bifurcated to provide arms Il and l2, between which passes pivot pin il, on which is mounted lever Il, having interior slot Il and ball gripping portion Il, the lever Il being of thickness equal to the width of the slot l1 between the furcations of the valve stem, so that it may be slid down therein when not in use. A cap Il, shown in Figures l and 8, is provided for sealing the device when not in use.

As shown in Figure 2, to operate the device the lever Il is lifted upwardly, so that its end contacts with the pivot pin Il of the valve stem, and so that one of its surfaces Il presses against surface il of the head. When the ball l0 at the end of the lever is displaced in the direction of the arrow in Figure 2, with surface ll of the head serving as the fulcrum valve stem l0 is moved upwardly in the direction of the arrow against the compression of spring Il and against the resistance of diaphragm u, causing a compression of 'spring Il and annular displacement and distortion of the body portion of the diaphragm u in the direction of the arrow. thus placing the same under tension. By this action the valve ll is displaced from its seat 26 and the teat 4l displaced from bore 22, permitting liquid medium contained within the base Il to pass, by virtue of the gaseous pressure therein, through port 22, into chamber 28, to bore 2l, through screen 2l, into bore Il of the nipple, and through the tine aperture 8| at the extremity thereof; the. liquid under gas pressure, at the time it reaches the aperture 3l, being, by virtue of its tortuous path, through reduced apertures, brought tol a condition of tine atomization, as it strikes the air. When pressure against lever M is released. diaphragm I4 and spring 50 collectively tend to return to their original position, bringing valve 3l back onto seat 2l, 'to seal the bore or port 22.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claim.

I claim:

In an atomizer, a container for liquids to be sprayed, a conduit in the head of the container leading from the interior to an outlet thereof, a valve for sealing said conduit between the interior and the outlet, a coil spring acting axially, and a diaphragm acting peripherally of said valve to maintain the same in sealing position, and a lever attachable to one end of the said valve and adapted to be fulcrumed on the head of said container for displacing said valve against the action of said spring and diaphragm, said valve having s. chamber in which said lever rests when not in use, the said lever having a slot and said valve a pin, whereby said lever may be displaced from the valve chamber for fulcrumlng action on the head of said container at right angles to said valve.
