10 Claims.

This invention relates to atomizers for perfume, toilet water, or the like, and particularly to such an atomizer of small and compact form for carrying in a pocket or purse.

The primary object of the invention is the provision of an atomizer of this character of improved construction, whereby to enhance the practicability and commercial value and to increase the operating efficiency thereof.

A further object of the invention is the provision of an atomizer of this character of unique construction and arrangement of parts, whereby the pump and liquid container are axially aligned and entirely separated and out of communication orie with another.

Other objects and advantages of the invention will be apparent from the following detailed description and from the accompanying drawing illustrating one embodiment thereof, in which- Figure 1 is an enlarged. central longitudinal section of an atomizer embodying the invention, with the parts in closed position and with parts in full; Fig. 2 is a similar view reduced in size from that of Fig. l, but enlarged with respect to commercial size, with the parts in completely separated position; Fig. 3 is a side elevation of Fig. 2 turned a quarter way around;

Fig. 4 is a similar side elevation in the same position as Fig. 2, and Figs. 5 and 6 are sections on the lines 5-5 and 6-6 Ataken respectively on Figs. 1 and 2, with the former reduced in s1ze.

By reference to the drawing, it will be noted that the device embodying the invention includes a compressor cylinder I and a receptacle 2, for

the liquid to be sprayed, disposed in axial alignment and one telescoped with the other to permit relative axial reciprocatorry movements thereof. In the present instance, the inner end of the wall of the cylinder I has an extension or tiiirt'portion 3 which telescopes over the side The receptacle 2 has its inner end closed to form a bottom 6, while its outer end is open preferably terminating in an outwardly directed radial edge ilange l.

A bushing 9` is flxedly secured in the outer end portion of the receptacle wall 4, being sealed therein in any suitable manner, and has its outer end ilanged to engage over the arged edge 1 of said wall. A plug I0 is removably threaded into the bushing 9 and has suitable gasket seating engagement therewith to prevent leakage.

A protecting sleeve II is provided on the receptacle 2 around its Wall 4 in spaced relation 55 thereto, so as to receive the extension or skirt end 3 of the cylinder I\ therebetween. This sleeve is attached to the receptacle by inwardly flanging its outer end and depressing such flange to provide a countersunk inwardly projecting edge ilange in coaction with the edge flange 1 of the receptacle wall and between it and the outwardly flanged edge of the bushing 9, which latter seats within the depressed portionof the sleeve end and serves both to center the sleeve relative to the receptacle and to hold the inturned sleeve end in engagement with the receptacle wall. in fixed engagement .with such wall but is free to turn relative thereto for the purpose hereinafter described.

A discharge nozzle I2 is mounted in the bottom or inner closed end `of the receptacle 2 adjacent to the outer edge of the bottom and has its bore in communication with the interior of the receptacle preferably through a porous packing material I3 of felt, or other suitable material, in the bottom of the receptacle. This nozzle is of shallow form and projects only a short distance from the end of the receptacle. The receptacle is also provided with a vent tube I4 which preferably opens into the receptacle near its outer end, While its other end is projected through an opening in the bottom of the receptacle near one edge thereof and preferably in a position substantially diametrically opposed to the nozzle I2. The outer end of the vent tube opens to the atmosphere and such end is substantially in the same cross plane of the device as the discharge end of the nozzle I2.

A stem I8 is fixed to the inner or bottom end of the receptacle 2 intermediate the nozzle I2 and vent tube I4 and projects axially therefrom into theA compressor cylinder I. In the present instancel this stem is attached to the receptacle by providing the inner end of the stem with an axially projecting lug I9 which is inse'ted into a centrally disposed inwardly flanged opening in the bottom of the receptacle and flrmlysecured therein by cementing, soldering, or any other suitable manner. The stem I8 projects through a web 20 in the inner end of the body portion of the cylinder' |suoh web cooperating with the outer closed end of the cylinder i to form a compressor chamber 2I. Within this chamber the ,stem I8 is provided with a compressor plunger 22 of anysuitable construction. The outer end of the chamber 2| is closed by a plug 23 which, in the present instance, is threaded in the cylinder and is pref- The sleeve, however, is not held erably sealed therein by cementing. An expansion spring 24 of the conical type is disposed in the chamber 2| with one end thrust against the plug 23 and its 'other end thrust against the piston 22.

The stem |8 has a longitudinally extending bore 25 therein extending to near the inner end of the stem with its outer end in communication with the interior of the compressor chamber 2| through a small passage 26 in a plug 21. which is secured in the outer end of the stern bore and serves, in the present instance, to attach the piston 22 to the stem. The instroke of the piston within the compressor chamber is limited by the outer end of the plug 21 striking an inwardly projected central portion of the plug 23.

A discharge orice 30 for air compressed within the chamber 2| is provided in the stem wall from the inner end portion of the stem bore 25 in position to direct its discharge across the outer end of the discharge nozzle |2 in impinging relation thereto, so as to draw liquid from the receptacle 2 through the nozzle and porous packing I3 and effect its discharge in spray-form from the nozzle transversely thereof and outwardly with respect to the stem. 'This spray discharge from' the nozzle is directed outwardly from the device through an elongated slot or opening 3| provided in the extension or skirt portion 3 of the cylinder wall .The opening 3| extends .from the inner open end of the Wall portion 3 to near the web 20 and is of suicient length for -the nozzle I2 to be exposed to the outside during substantially the' full operating stroke ofthe compressor. `When the cylinder and receptacle 2 are in completely telescoped or compressed relation, the outlet ends of the nozzle |2 and vent tubev Mabearagainst and are closed by a gasket 33 which' seats against the receptacle side of the web 20. It is thus apparent that when the two parts of the atomizer are in closed relation the two outlets from the receptacle 2 are sealed to prevent any leakage therefrom.

The stem 3 is preferably provided with a feather or rib 34 at one side thereof Working in a recess in the web to prevent relative turning of the' cylinder and receptacle 2. When the atomizer parts are in closed relation, substantially as shown in Fig. 1, the sleeve completely covers and closes the opening 3| in the skirt portion of the cylinder This sleeve also has cooperative action with such skirt portion to limit theinward Working strokes of the parts. so as to prevent a complete closing of the opening 3| during a spraying operation of the device, and also to effect a locking of the parts in completely closed relation. For this purpose, the skirt portion 3 is provided at opposite sides thereof with longitudinally extending :grooves or recesses 36 receiving guide pins 31 in the a-djacent end portion of the sleeve Such recesses have straight portions suiiiciently long to take care of the full operating stroke of the parts, such stroke being stopped at its inner end by engagement of the pins 31 with aligned shoulders 38 in the inner end portions of the recesses 36. The inner ends of the recesses 36 adjacent the shoulders 38 are oiset and then continue inward and laterally in bayonet slot form, as shown at 39, so that the pins may be turned into the laterally angled ends of such portions to lock the atomizer parts in closed relation with the gasket 33 in sealing engagement with the projecting ends of the nozzle I2 and vent tube I4.

In an operation of the device, presuming the parts to be in closed locked relation, the sleeve is rst turned to release its pins 31 from the laterally extending end portions of the recessed parts 39, thereby permitting the sleeve and detached receptacle 2 to be moved outward relative to the cylinder to the full limit of the outward stroke, by the action of the spring 24, which movement carries the piston 32 to the inner end of the cylinder. The operator may now effect successive inward movements or strokes of the parts ofA the device by applying successive pressure on the ends of the device between the thumb and a linger of a hand by which it is held. This action compresses air Within the compressor chamber 2| and such air forcefully discharges from the compressor through the orice 30 in a small stream which is directed across the liquid discharge nozzle |2, thereby effecting a drawing of liquid from the receptacle and a discharge of the same in spray-form laterally from the device through the opening 3|.

It is apparent that I have provided a very compact and eilicient atomizer of the character described, in which the compressor unit and liquid container are disposed at opposite ends, with the plunger of the compressor unit xedly projecting from the inner end of the container and also with the discharge from the container arranged between the adjacent ends of the compressor unit and container and adapted to have its discharge transversely thereof. It is also apparent that both the liquid discharge nozzle and the air vent are `disposed in enclosed protected relation Within the device and are completely sealed to prevent leakage when the compressor cylinder and container ar'e in cl'osed or compressed relation, and'also that there is no communication at any time` between the interior of the compressor cylinder and that of the liquid container.

I wish it understood that my invention is not limited to any specic construction, arrangement or form o'f the parts, as it is capable oi numerous vmodifications and changes Without departing from the spirit of the claims.
