In Canada June 6, 1946 "Introduction The invention relates to atomizers, and more particularly to a portable atomizer for dispensing perfume. A

The invention comprises an atomizing nozzle which is simple to manufacture and assemble as well as easy to maintain. The. majority of pocket atomizers, which are adaptable for dispensing perfume, comprise, along with the fluid reservoir and pump, a. tube .connected with the fluid reservoir and another tube. through which air is, pumped. As the proper atomizer function depends upon the relative position of the ends 'of these tubes,.proper adjustment is difficult to maintain, and as the tube connected with the fluid reservoir would permit free leakage of the fluid, it has been necessary to cover the end of this tube for atomizers which were to be, carried in the pocket or purse.

As will be understoodthe adding of movable 7 parts likely to become deformed, makes continual maintenance necessary.

Objects An object of this invention is the provision of an atomizing nozzle which is contained within the body of the-atomizer, and which eliminates the use of any moving parts suchas a cover.

A further object of this invention is the provision of a perfume atomizer which is simple in construction and. simple in operation.

Another object of thisinvention is the construction of an atomizer body from a single billet of alloy material, impervious to perfume, which provides for cheaper manufacture.

Preferred structure A preferred structure fulfilling the'objects of this invention comprises a thin substantially rectangular casing, made from a solid billet of material, in which borings constitute a fluid chamber, a pump cylinder, and a recess which holds the atomizing nozzle in communication with fluid chamber and the pump cylinder. The atomizing nozzle, which will be more fully explained later, comprises two parts, namely a primary body member and a secondary insert. Borings and clearances withinand between the primary and secondary members provide an air passage and a fluid passage, which in conjunction with a piston workable in the pump cylinder, dispenses perfume in atomized or spray form.

Detailed description Still other features will be apparent in the course of the following detailed description in which reference is made to the accompanying drawings, wherein:

Figure 7 is an end view of the secondary insert member showing the flats on the bevel face of this member.

Referring to Figure 1 of the drawing, the,cas-

ing I0 is a solid billet of material in which the vertical boring l2 forms a fluid chamber and the V verticalboring [4 forms a pump cylinder which are connected to a horizontal, transverse boring IBby the passages 18 and 20. The transverse boring I6 is closedat its rear end by a plug I l and. opens at its opposite, forward end through an oblique edge surface l9 defining a relieved cornerportion ofthe generally rectangular billet or casing I0. Forced, to a dry fit, into the opening of the chamber I 2, is a collar 22. A boring in. this collar is threaded toreceivea closure 24, which is suitably sealed against leakage of fluid by a washer 26. A minute boring 28 in the collar 22 provides for the egress of air, from the fluid chamber I2, which is displaced as the closure 24 is being screwed up to a point of ultimately sealing the chamber. Air may escape through the boring 28, up to the time of being sealed by the washer 26. A lateralgroove 30 in the outside face of the closure 24- is provided so that the closure may be tightened or unscrewed by the use of an ordinarycoin, I I

The piston which forms a movable part of the pumping mechanism comprises a solid stem 32 which is threaded at one end to receive a washer 34. This washer 34 forms a base for a leather sealing ring 36 which has an upwardly extending 'collar, which is forced outwardly by a metal engaging head, consisting of a fluted wheel member 48 is retained on the lower end of the stem 32 by a snap ring 50 which is engaged in the detents 52 on the wheel and 54 on the stem 32. Protruding wing members 56which are formed on alternate quarters of the circumference of the wheel member 48, are caughtunder the flange head of a retaining screw .58 which is screwed into the body l0. As will be understood, a quarter turn of the head}!!! will release the wings .56 from'c'ontact with the retainer screw 58,'there'- *th'e'boring 72 in a dry fit sealing same.

3 by allowing the plunger to extend to an.

open positionby force of the spring 44.

Atomieer nozzle assembly is a reamed out beveled face joining the outside 7 circumferences of the two bores as shown at 16.

Through the casing to the boring 12 'is a port 18 15 adapted to communicate with the boring iii in the body member 10, when the casing "ii! is forced into the open, enlarged end of the transverse passage [6. The-portion of this port 18 which communicates. with the fluid char'nberv i2 is 20 countersunk at 80 to provide a globular formation to the fluid as it enters the boring l2."

The secondary insert consists ofa'cylindrical member, of hollow plug, 82 having a step-down*"- diameter, that isthe portion 84 is-ofa' circumference adapted to fit into the circumference of The diameter of the portion 86' is slightly smaller than the diameter of i2 or 84 so that when the hollow plug 82 is inserted into the boring T2 the difference in' circumferences form a 'chambe'rtii which is in communication in the fluid chamber I2 by the boring i8 and the port 18 which co "incide. The end of the insert 82 adjoining the circumference '86 is machined .down to'form a be'vel face fifi matching and fitting thebevel face Hi-in the primary member. A central boring 92 through the secondary insert is connected with a smaller boring 94 completi t 1 'the insertw-A' tube 96 having a minute central 40 orifice-is inserted in the small boring 94. This tube96 may beeliminated if the manufacturer finds that-a boring ofsmall enough circumference L may be achievedany other way. Flats 98 are .machined on the beveled surface 90, forming a communication from the chamber 88 to the clearance between the outside circumference of tube ,96 and the boring 14. Withthe atomizer. nozzle, consisting of outer casing 10 and the innercylindrical.member-82 in assembled relation and disposedwithin the enlarged forwardend of the transverse passage IS, the forward end of the nozzle projects through theoblique. surface I 9 of the block and lies With- .in-the. relieved corner or, in other Words within 5 the. space defined by projections of the side and edgefaces of. the casing or billet l0.

Operation .The operation ofthis atomizer uses the same law which governs most types of atomizers, namely that of a stream of. airpassing an orifice ,containing liquid and in so .doing drawing the liquid from its container, the pressure of the air vapourizing the liquid as it is drawn out. As 55 will be noted, with reference to Figure 1, the air is forced from the. pump cylinder through the borings 2D and I6. into the boring 92 of the sec- 'ondary insert. and thence through the minute opening in the tube 96.130 the atmosphere. .Perfume which has been allowed toenter the chamber d8 of the nozzle, by shaking or normal. car.- rying of the atomizer-in a pocket or purse, is distributed around the circumference 86. The passage of the air through the orifice in tube 9.6

, art.

llcauses the perfume to be drawn out past the j flats 98 and to mix with the air in the opening 14 of the primary body member, the velocity of thev pumped air causing the minute quantity of perfume to break up into particles and to emerge from the borings 14 with the air in an atomized form.

Advantages As will be noted by the detailed description and the operation of this atomizer, the only moving part for the operation of the atomizer is the piston of the pump. The tube 96 of the secondary insert of the nozzle is protected by the somewhat rounded :and blunt nose of the primary body member of the nozzle. Therefore, it will be seen that replacement or maintenance due to everyday use will be almost eliminated.

A further advantage of this type of atomizer is that the amount of perfume which may be dispensed at any one time is limited to the amount of perfume which is held in the chamber 88 'in the nozzle assembly, therefore, there .is no chance of having the air stream draw a large quantity of perfume from the reservoir and deposit it more or less in its solid form.

In the preferred form tested, the clearance betweenthe circumference 86 and E2 is approximately /1000 of an inch, therefore, limiting the amount of perfume contained within the chamber toa very minute quantity.

-A further advantage of this type. of atomizer is that with the use of a solid billet'forming the body, the collars 22 and 38 are driven tightly into the borings and the nozzle assembly is also assembled and fitted into the body by a dry fit, thus eliminating all soldering and cutting down on the time and cost factor in manufacturing.

It will be understood that, without departing from the scope ofthe claims, various modifications may be made in the specific expedients described. .The latter are illustrative only, and not offered in a restrictive sense, it being desired that only such limitations shall be placed thereon as may. be required. by the state of the prior The sub-titles used throughout the specification are merely to simplify reference thereto and should otherwise be disregarded.
