P0117 DER DISPENSER.

Application led .Tune 20, 1924.` Serial No. 721,207.

T o all whom t may concern Bc it known that I, JOHN J; CROWLEY, citizen of the United States, residing at Caniibridge, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Powder Dispensers, of which the following is a specification.

This invention relates chiefly to means for dispensing talcum and other toilet powders.

One object of this invention is to provide a dispenser including a powder reservoir, a distributing nozzle, and an air ejector cooperating with the reservoir and nozzle in such manner that a forcible discharge of powder from the reservoir through the nozzle may be caused by air forced by said ejector without liability of escape of powder from the reservoir when the ejector is not in operation.

Another object is to providea dispenser characterized as above stated, the distributing nozzle being adapted to cause the scattering or wide distribution of the discharged powder, so that a considerable area may be quickly and evenly powdered.

Of the accompanying drawings forming a part of this specification,-

Figure 1 shows in longitudinal section, a powder dispenser embodying the invention, a portion of the air ejector and the air nozzle being shown in elevation.

Figure 2 is a section on line 2 2 of Figure 1.

Fig. 3 shows partly in section and partly in elevation, a different and the preferred construction of thedistrilmting nozzle.

F igure i is an enlargement of a portion of Figure 3.

Figures 5 and 6 are views similar to Figure 3 showing modifications.

The same reference characters indicate th same parts in all of the figures.

In the drawings, 12 designates an air nozzle which may be a length of tubing of any suitable material. The air nozzle is enclosed for the major portion of its length in a powder reservoir 13, preferably cylindrical and of glass or other suit-able material. In this instance, one end of the reservoir is formed by a head 14 screwed upon the body of the reservoir, as shown by Figure 1, the other end of the reservoir being formed by a breast 15 which may be integral with the body, as shown by Figure 1, or detachably secured thereto, as shown by Figtracted intake portion 17, a contracted outlet portion 18, and an intermediate enlarged portion or chamber 19. While the distributing nozzle may be substantially spherical, as shown by Figure 1I prefer to form it as shown by Figure 3, the breast 15 forming one wall of the enlarged portion or chainber 19. Vifith the air nozzle 12 is associated an air ejector 2O which may be a normally expanded compressible rubber bulb having the usual valve adapted to admit air when the bulb expands and to be closed when the bulb is compressed to force air through the air nozzle. As here shown, the bulb is provided with a neck 21 secured upon a thread-- ed nipple on the head 14. The intake end portion of the air nozzle passes through a stuffing box 22 on the head, preventing air forced by the ejector from entering the reservoir.

I provide means for permitting a limited flow of powder from the reservoir to the distributing nozzle, the arrangement being such that air forced through the air nozzle induces a flow of powder from the reservoirv into the distributing nozzle and ejects it from the latter.

In the preferred arrangement shown by Figures 1, 3 and 4, the discharge end of the air nozzle 12 is seated on the breast around the contracted portion 17, and is provided with notches 23 constituting vents through which a limited quantity of powder passes when air is forced through the air nozzle. In the arrangement shown by Figure 5the discharge end of the Vair tube is slightly spaced from the portion 17 to form an annular vent 24. In the arrangement shown by Figure G, the discharge end of the air nozzle is seated on the bore portion 17, and is provided with orifices 25 constituting vents wholly within the air nozzle. It will be seen that the reservoir has a powder' outletformed either by a plurality of vents or by a single annular vent communicating with the distributing nozzle, and of relatively small capacity, which is much smaller than that of the air nozzle. The, result is that a jet of air forced through the air nozzle sucks powder into its path and forces the powder through the distributing nozzle. Owing to the relatively Small capacity of the outlet connecting the reservoir with the distributing nozzle, there is no liability of acciden tal escape of powder fromk the reservoir. rlie powder laden air expands in the portion or chamber 19, so that the powder is agitated and held in suspension in said chamber. The air is com-pressed before passing through the outlet portion 18 and eX- pands in leaving said outlet portion, so that the powder is scattered inV the form of a v fine mist or spray. The dispenser is therefore well adapted for distributing or dusting toilet powder evenly on large surfaces of a human body, and` may be manipulated to powder the back as well as the front portions ofl the body.

I claim:

A powder dispenser comprising an air nozzle, a powder reservoir enclosing the air nozzle, and having a distributing nozzle alined with the air nozzle, and an air ejector associated with the air nozzle, means being provided for permitting a limited flow of powder from the reservoir into the distributing nozzle, the arrangement being such that air forced through the air nozzle induces a flow of powder from the reservoir and ejects the powder from the distributing nozzle, said distributing nozzle having a contracted intake portion, a contracted outlet portion, and an intermediate enlarged chamber portion, the nozzle beingV adapted to cause an agitation of powder forced through it and the scattering of the discharged powder.

In testimony whereof I have aiiixed my signature.

- JOHNv J. CROWLEY.
