" Claims. (or. 29,948)

This invention is an improved form of head for atomizers and is particularly adapted for use in spraying or atomizing fluids such as permanent waving fluid, lacquers, and the like and provides 5 a device which will not easily become clogged, a matter which has made the-spraying of these quickly evaporable fluids impossible to the other types of atomizers.

A further object of the device is to provide ETI'Ei'OXHlZEI' head which may be easily disassembled for cleaning.

A still further object of this invention is the provision of a head for an atomizer which may j be easily closed.

A still further highly important object of this invention is the provision of a device of the described class which is simple to manufacture and which is composed of a relatively few number of parts.

Other and further objects of this invention will be apparent from the drawing and from the detailed specification which follows.

On the drawing Fig. 1 is a cross sectional view of the device showing particularly the'various operating parts hereinafter described and particularly how the needle extends into the downwardly extending tube of the atomizer head.

Fig. 2 is a cross sectional View taken of the line 2-2 of Fig. 1.

Fig. 3* is a side elevational view of the head attached to a conventional receptacle and having a conventional hand operated bulb attached to the same.

form of the device, this view particularly illustrating a modified form of closure for the exhaust aperture in the atomizer head.

As shown on the drawing, the letter A indicates a conventional bottle or similar receptacle adapted to hold a quantity of whatever liquid it is desired to atomize. The numeral I is used to indicate the main body portion of the atomizer head which is adapted to be preferably screwed onto an appropriately threaded neck of the bottle or receptacle A by means of integral screw threaded portion la. The main body portion I- is partially closed above the screw threads la by a transverse portion lbwhich, as shown 50 in Fig. 1:, extends substantially across the lowermost portion of the head proper and serves as a base or mounting for the normally perpendicularly extending tube 2 which is adapted as shown to extend substantially into the receptacle A and liquid contained therein- An aperture Ic is Fig. 4 is a side elevational view of a modified ing the conventional rubber tube B which, in

preferred form, connects to a manually operable bulb C supplying the necessary force of air to atomize the fluid.

The head I" is provided with an aperture at the top substantially as shown in Fig. l,- this aperture being internally screw threaded to receive the cap 5 which, as shown, is exteriorly threaded at its lowermost portion 5a so as to entirely enclose the top of the main body portion knurled rim 5!)" permitting the cap to be easily removed from body portion I. Further, as shown in Fig. I the cap 5 has an outwardly extending aperture which-is internally screw threaded as shown to receive the portion 6 which, being. exteriorly screw threaded as shown, is adapted to completely close the top of portion 5 whenin its forwardmost position. Portion 6 has: a knurled cap portion 6a which permits easy screwing of the portion 6 in or out of the cap as desired.

Placed on the end in relatively close juxtaposition to the screw threads 6b of portion 6 is an outwardlyextending needle I which is adapted to fit into the reduced portion 2a of the downwardly extending tube 2 when portion 6' is screwed to its farthest inwardly position. The purpose of the said needle or rod 1 is to close portion 2a and tube 2 and to serve additionally as a cleaning member for portion 2a;

The main body portion I of the invention is closable by a rotatable closure, the preferred form of which is shown in Figs. 1, 2 and 3', and a modifled form of which is shown in Fig. 4. In that preferred form shown in" the first 3' aforementionedfigures the closure consists of a disc- 8 which is bent inwardly as particularly shown in Fig. I sothat when it comesinto registry with aperture l d it: will snap substantially into said aperture effectively closing the same. The disc 8 has. a. downwardly extending. portion 811 which iscomposed of an integral. sheet. of metal the I. A preferred form of cap or top 5 is shown on the drawing, in preferred form having a side edges 8b of which are forced backwardly toward one another and over the downwardly extending substantially U-shaped portion 9a of the split ring 9. Ring 9 fits, as shown in Fig. 1, in an annular recessed portion of the body portion I and immediately under the knurled portion b, of top portion 5. Further, the ring 9 is split as shown in Fig. 2 at its rearward central portion permitting said ring 9 to expand and thus permitting disc 8 to slide around the side of main body portion I and also permitting the said disc 8 to snap substantially into a relatively fixed position in aperture Id thus closing the same.

In that modified form shown in Fig. 4 the only is shown in the side elevation. In this modified form the closure consists of an annular portion I0 substantially enclosing the uppermost part of body portion I and being widened at its forwardmost portion so as to practically enclose the entire foremost part of body portion I and being rotatable thereon in such a manner that when handle Illa, is turned at substantially a right angle to portion 4 or aperture Id the spray head is in operable position and when portion III is turned by means of handle IDa substantially to that position shown in Fig. 4 the aperture Id is covered and effectively closed. There is no spring-like action in the modified form shown in Fig. 4 as contrasted to that preferred form shown in Figs. 1, 2 and 3 and it is imperative, therefore, that portion II] be only slightly larger than the main body portion I and retained thereon by friction which must be suflicient to substantially close aperture Id when handle portion Illa and integral annular portion ID are in the position shown in Fig. 4.

It should be obvious, therefore, from the detailed drawing and from the above detailed description which I have made that I have provided a head for an atomizer or spray which may be easily taken apart for cleaning and which may be easily and effectively closed in such a manner that quick drying fluids will not easily clog the same. When it is desired to use my invention the portion 6 is screwed upwardly thus lifting the integrally formed needle I 'I out of the reduced portion 2a of tube 2 in which it normally reposes when portion 6 is screwed down to its lowermost position. Then, by turning the closure portion 8 or the'modifled form It] shown in Fig. 4 away from aperture Id, the device is ready for use. Partially open bulb C will force air across the uppermost opening in tube 2a and has a tendency in manner well known to atomize the liquid which is blown out through aperture Id. Any of the liquid which does not pass through aperture Id will be collected in the main body portion I and will seep back into the receptacle A through the aperture is in transverse portion I b.

The usual lacquers and hair drying fluids and the like are so quickly evaporable that it is necessary, in most instances, to close the atomizer and screw down portion 6 whenever the atomizer is to be put out of operation for even a short period of time. At such times all the operator need do is to push the closure 8 into registry with aperture Id or, in using that modified form shown,in Fig. 4, to rotate portion I0 so that it passes over the aperture Id, and then screw down portion 6 so that needle I extends substantially into the reduced portion 2a. of tube 2. Reversal of the aforementioned manner of handling again puts the atomizer head into operable position.

While I have described this invention in considerable and in quite specific detail I do not wish to be limited to the exact structure shown except as limited by the appended claims, and various changes may be made in the embodiment of the invention herein specifically described without departing from or sacrificing any of the advantages -of the invention or any features thereof, and nothing herein shall be construed as limitations upon the invention, its concept or structural embodiment as to the whole or any part thereof except as defined in the appended claims.
