- INVENTOR 20ml? 1 .izlwlzsolz BY W W M ATTORNEY Patented Mar. 7, 1933 v UNITED STATES PATENT OFFICE LOUIS V. ARONSON, OF NEWARK, NEW JERSEY, .A SSIGNOR TO ART METAL WORKS, INC.,

A CORPORATION OF NEW JERSEY n'romzan This invention relates to atomizers of the type adapted to be supported on a table or the like or, carried in the pocket or in a hand bag, and particularly concerns improvements in the atomizer shown in my co-pending application Serial No. 306,148 filed September 15, 1928, atomizers, this application having matured into U. S. Letters Patent No. 1,791,440, granted February 3, 1930.

An object of the invention is to simpl fy the practical operation of the device, to 1ncrease the economy of its manufacture, and to enhance the durability of the construction and hence lengthen the operative life of the atomizer.

Further and more specific objects, features, and advantages will more clearly appear from the detailed description given below taken in connection with the accompanying drawings which form part of the specification, which illustrate certain embodiments of the invention, and in which:

Fig. 1 is a perspective view of a preferred form of the improved construction;

Fig. 2 is a vertical longitudinal section taken through the device shown in Fig. 1;

Fig. 3 is a perspective view of a modified form of the device shown with the cover in closed position;

Fig. 4 is a similar view showing the cover in open position;

Fig. 5 is a vertical longitudinal section through the device with the cover in open position;

Fig. 6 is a partial similar section of the top of the device showing the cover in closed position;

Fig. 7 is a transverse section taken on the line 77 of Fig. 6.

Referring to Figs. 1 and 2, what I now consider to be the preferred form of the device comprises a relatively tall thin casing 10 to which a top plate 11 and a bottom plate 12 are suitably connected, as by welding, and forming therewithin a chamber 13 for liquid, such as perfume. Upon the bottom plate.

12 is mounted a plate 14 welded or otherwise fastened thereto, this constituting a further closure. Plate 14 has an offset socket portion 15 with a threaded bore 16 to receive a threaded plug or stopper 17, on the lower end of which is an enlarged head 18 lyin flush with the lower face of plate 12in the 0 set portion or recess formed bysocket portion 15. By turning head 18 the stopper 17 can hennscre'wed topermit fresh liquid to be introduced into the chamber 13. A washer 19 lies between the head 18 and the adjacent face of the offset portion of the plate 14. The stopper 17 is preferably made of metal and has an inner recess 20 to tightly receive a metal cap 21 having an aperture loosely retaining the end of a chain or flexible connection 22. The other end of the chain 22 is slidably con' nected to a tube 23 within the casing. Thus when the stopper is removed it is connected by the chain to an element within the casing so that it cannot be removed and lost.

Mounted on the top plate 11 is metallic head 24. This head or block 24 has therein a horizontal passage 25 and a vertical bore 26. Passage 25 opens at the inner end into the bore 26 and at the other end to the face of the block 24. A nozzle member 27 is threaded into the open end ofthe passage 25, and extends laterally across the top of the atomizer; The bore 26'receives a plug 28 having a flat head 29 lying in a recess 30 in the top of the block 24. The plug 28 has a central bore 31 and cross bores 32 leading to a pcripheral groove 33 connecting the bore 31 with the bore 25 in the block 24. The lower end of the plug 28 is threaded to receive the upper threaded end of the air tube 23. Just below the top plate 11 the tube 23 is slightly enlarged, as at 34, and when the plug 29 is turned by inserting a screw driver in the slot 35 in the head 29, the tube 23 will be drawn up into closer engagement with the plug 28, and the enlarged portion 34 will be drawn tightly against the face of the top plate 11. The lower end of the tube 23 is connected to the bottom of an air pump cylinder 36. The bottom of the cylinder 36 is closed by a cap 37 welded therein, and resting on the inner face of the closure plate 14. The upper end of the cylinder 36'is fitted tightly in an aperture in the top plate 11 and closed by a cap 38 threaded therein. The cap 38 has a flange 39 resting on the top of the plate 11.

A central aperture 40 in the cap 38 ermits of the passage of the pumppiston ro 41, on the upper end of which the operatlng head 42 is threaded. This head 42 is provlded with a lower outwardly extending circular flange 43 functioning as hereinafter described. The lower end 44 of the piston rod 41 is reduced and .threaded and slidably receives two metallic washers 45 and 46 between which the flexible washer 47 is disposed and acts as a piston in the cylinder 36. A hollow interiorly threaded cup-shaped cap 48 is threaded on to the lower threaded end 44 of the piston rod 41, and holds the washers 45, 46 and 47 in place. Thiscap 48 has an aperture 49 in its end wall through WlllCll extends the lower end of a valve stem 50. Midway of the stem 50 is a valve 51 pressed against the valve seat 52 on the lower end 44 of the piston rod 41 by means of a valve spring 53 housed within the cap 48'. The upper end of the valve stem 50 extends into a bore 54 in the lower end 44 of the piston rod 41. The upper end of this bore 54 openslaterally into the cylinder 36 above the piston washer 45 to provide passage for air ,from one side of the piston to the other. Between the cap 37 in the bottom of the cylinder 36 and the lower piston washer 46 is disposed a coiled spring 50a, the upper end of which is coiled around the cap 48. This spring tends always to move the piston rod 41 upwardly out of the cylinder.

A liquid tube 55 extends downwardly into the chamber 13. The upper end of this tube is preferably welded to the inner wall of a hollow threaded sleeve 56 threadably adjusted in an aperture in the top plate 11. This sleeve has a top flat head 57 by which it is turned, and which rests against a washer 58 disposed on top of the plate 11'. A liquid nozzle member 59 is suitably fitted into the upper end of the tube 55 and extends above the top of the plate 11 to a point on a level with the horizontally extending end of the air nozzle member 27. Y I

When the device is not in use the nozzle member 59 is engaged by a flexible stopper element 60, preferably a sleeve of-rubber, to keep the liquid within the chamber from evaporating and dirt from getting into the nozzle. This stopper 60 is supported on a stem 61 dependent from a threaded cap 62 screwed into an aperture on a cover member. The cover member comprises a top wall 63 and a dependent side wall 64 which, when the cover member is in its closed position shown in Fig. 2, will enclose the air and liquid nozzles and the block 24. The rear end ofthe cover is provided with a projecting ear 65. This ear lies over the flange 43 on the head of the piston rod 41 when the cover is in its closed position and the head 42 is in its lowermost position. This relation is shown in Fig. 2. The cover is pivoted on a menace? shaft 66 disposed at the rear of the block 24. Intermediate the ends of the shaft 66 the block 24 is cut away, as shown at 67 in Fig. 1, to form a recess to house a spring 68, which is coiled around the shaft 66 with one extended end bearing in a groove 69 in the top of the block 24, and with the other end of the spring 68 bearing under the top wall 63 of the cover. The tendency of this spring is to snap the cover to its open position at all times.

Also carried by the cover is a second stopper 70, similar in construction and operation to the stopper or sleeve 60 above described, and adapted to be disposed over a vent nipple 71 on the top plate 11 when the cover is in its closed position. This vent nipple 71 ordinarily allows air to flow into the chamber 13 as the liquid is drawn out through the nozzle 59.

Considering the parts in the position shown in Fig. 2, the plunger head 42 when depressed, will permit the spring 68 to snap the cover up to open position. This uncovers the air, liquid, and the vent nozzles. Reciprocation of the piston rod by the finger will cause air to be forced out through the nozzle 27 horizontally across the top of the liquid nozzle 59, thus drawing the liquid out of said nozzle and projecting it in a fine spray. When the plunger is moved down to its lowermost position and the cover then closed, the plunger, if then released, will move up until the flange 43 strikes beneath the car 65, and this upward tendency of the plunger, due to the action of the spring 50a, will keep the cover in its closed position. This interlocking action will also keep the plunger in its depressed position. Because of the circular flange, the plunger will engage beneath the car 65 no matter in what position the plunger may be due to its having been rotated. When the device is to be filled with liquid, the stopper 18 is unscrewed and the liquid poured into the openingthus formed, the stopper being retained suspended upon the chain 22, and thus cannot be lost. It is obvious that the construction above described, is simple and yet rugged enough to insure a long life to the device under constant use. It is small and yet of a size and design to be readily carried in the pocket or in a hand bag.

In the modified form shown in Figs. 3-7 inclusive, the device comprises a casing 72 having top and bottom plates 73 and 74 with an innerclosure plate 75 at the bottom, which is provided with an offset portion 76 forming a recess 77 for a stopper 78. The stopper has a head 79 lying flush with the bottom plate 74. A stem 80 extends from the head 79 and has a threaded outer end 81 adapted to be thread- 1 ed into a threaded bore in the bottom of the oflset portion 76. The ofl'set portion 76 has a plurality of lateral passages 83 through which liquid will flow into the chamber 84 when the stopper 78 is removed and the liquid is poured into the chamber through the opening in the bottom plate 75.

In this form of the device, the liquid tube 85 extends from near the bottom of the chamber 84 through the top plate 73 and is fastened to the base 86 of an L-shaped plate suitably connected to the top plate 73. To the upright leg 87 of the L-shaped plate, is connected the horizontally disposed upper end of the air pipe or nozzle 88 on a level with the upper.

end of the liquid pipe or nozzle 85. The air pipe extends downwardly into the chamber 84 and connects to the bottom of the air pump cylinder 89 which rests on the bottom of the chamber on the plate 75. The upper end of the cylinder 89 is threaded, as at 90, andis adapted to receive a threaded plug 91 having a flange 92 resting on the top of the plate 73. This plug also threads into a threaded opening 93 in the top plate 73 beneath which the upper end of the cylinder 89 lies. This plug 91 has a central opening 94 through which slides a piston rod 95 having an upper head 96 provided, if desired, with a suitable notched flange which is suitably secured to a lower outwardly extending flange 97.

The lower end 98 of the piston rod 95 is reduced and threaded, and on this portion are slipped spaced washer plates of metal 99 and 100, between which is disposed a washer 101 of flexible material such as packing, to act as a piston. These washers are held in place on the piston by means of a threaded cupshaped cap 102 which is screwed on to the lower end of the piston rod 95. Within the cup-shaped cap 102 is disposed a valve 103 bearing against the lower end of a bore 106 in the piston rod 95 and held thereagainst by a spring 104. The lower wall of the cap 102 has an opening 105 leading to the lower portion of the cylinder 89. The bore 106 has a lateral passage 107 connecting with the upper side of the piston washer 101. Beneath the piston is disposed a coiled spring 108 bearing at its upper end against the washer 100, and at its lower end against the bottom of the cylinder. This spring tends at all times to force the piston rod 95 upwardly out of the cylinder.

The top plate 73 has a vent hole 109 (see Fig. 4) therein. The vent hole 109 and the nozzles 85 and 88 are normally covered by acover having a top wall 110 and a curving dependent side wall 111 which at its front end is provided with an outwardly flared curved flange 112 to fit around the base 86 of the L-shaped plate shown in Fig. 4. It will be seen from this. figure that the upright leg 87 of the L-shaped plate is also curved to conform to the inner shape of the forward end of the cover, so that when the cover is down over the liquid nozzle 85 said nozzle. is snugly enclosed to prevent evaporation of the perfume or liquid contained within the chamber 84. The nozzle 85 is not only en closed but a pin 113 on the cover enters the nozzle opening when the cover is in closed position, to further prevent evaporation and to prevent dirt from entering the nozzle. A pin 114 also on the cover, is adapted to close the vent hole 109 when the cover is in closed position. The side plate 111 of the cover at the rear thereof, is pierced with apertures to receive a shaft 115, the ends of which rest in apertures in spaced bearing plates 116 and 117 extending upward from the top plate 73. Around the shaft 115 within the cover, a spring 118 is coiled, one end of which bears against the under face of the cover, and the other end of which rests on the top plate 73, as shown clearly in Fig. 5. This spring tends always to snap the cover to itsopen position. At its rear end the cover is provided with an ear 119 which, when the cover is in closed position, as shown in Fig. 6, will lie over the flange 97 on the plunger head 96 when said head is in its lower position, and will prevent the head from rising further under the influence of the spring 108. The action of the spring 108 on the plunger head 96 will also help to keepthe cover in its closed position.

In the operation of this form of the invention, the slight depression of the plunger head fromthe position shown in Fig. 6, will permit the covcrto snap .up and uncover the nozzles and then the plunger is operated by the finger, while holding the device in the hand, to force air out of the nozzle 88 across the top of the liquid pipe 85 and draw liquid therefrom and'project it in a fine spray. To look the cover and the plunger in inoperative positions, it requires only that the plunger be moved to its lower position and then that the cover beclosed.

After this the plunger can be released and "it will then strike. under the ear 119, and

will thus be prevented from rising further, and will tend to keep the cover in closed position due to the pressure of the spring 108 on the plunger. The stopper 78 is removed for filling the chamber 84, by unscrewing the head 79 which removes the stem 81 from the threaded bore 82. This construction permits the stopper to be very firm- 1y seated in the offset portion 76. This device is simple, compact, and durable, and so constructed that when the parts are in their' inoperative positions no liquid canevaporate and no dirt can get into the vital parts. Also the cover and the plunger are kept in their closed positions, which permits them to be kept out of the way and not projecting so that they would catch in the'clothing or in the lining of a hand bag in which the device might be kept.

While I have described my-improvement in detail and with respect to a preferred form thereof, I do not desire to be limited to such 4 I I moans? details or form since many changes and modifications may be made and the invention embodied in other forms without departing from the spiritand scopeof the invention in its broader aspects.
