Description
Patented Jan. 6, 1942 UNITED STATES PATENT *OFFICE NECK DUSTER Dewey Cory, Dousman, Wis.
Application March 29, 1940, Serial No. 326,613
1 Claim.
This invention relates to improvements in brushes, and more particularly to a novel brush of the type known as a neck duster.
An object of the invention is to provide a device of the type which will dispense talcum powder or the like directly on the surface to be dusted. Other devices of the type now in use dispense the powder into the bristles of the brush. and in no case do they apply the powder to the surface on which it is to be used.
Another object of the invention is to provide a device of the type which will prevent caking of the powder within the container, and which will blow the proper amount of powder when operated by the user.
Other and further objects of the invention will appear as the description appears, reference being had to the accompanying drawing, in which:
Fig. l is a view in elevation of -a neck duster embodying my invention.
Fig. 2 is a view partly in elevation and partly in section of the device showing the powder reservoir and blower tube.
With reference more particularly to the drawing, the numeral III refers to the base of the brush. which 'is substantially cylindrical in form, having a cup formation or central bore at Il thereof, and the reduced bore at I2. The brush bristles I3 are embedded in conventional manner g at Il of the base III. A cap I5 is threadedly attached at I6 to the cylindrical wall I1, and serves as a retainer for the powder or the like I8.
The cap I5 is apertured at I9 thereof to seat the elastic or rubber bulb 20. A plug 2I having a central longitudinal bore is fitted into the neck 22 of the bulb 20 to retain the latter in said cap.
An ejector tube 23 is fixed in the reduced bore I2 of the base I0, and terminates in a flattened aperture 2l at its lower end 25. The upper end 28 of the tube 23 encircles the lower end of the cap I5. Adjacent the upper end 26 of tube. 23 are a plurality of apertures 21, and these may be placed in the reservoir portion of the tube with the placement thereof a matter of choice.
In use, particles of the powder IB will generally shake through the apertures 21 into the tube 23 during normal dusting movements of the brush, and when the bulb 20 returns to normal form after the compression thereof, a partial vacuum is created to draw powder from the cup formation II through the apertures 21 into the tube 23. In this way not too much of the powder I8 is ejected at one time, as would be the case if the reservoir or cup Il were subject to the direct draft of air expelled from the bulb 20. The restricted aperture 24 also causes some of the air to penetrate under pressure through apertures 21 into the cup II whichfserves to agitate or cloud the powder I8, which, as it settles, will in part fall through some or all of the apertures 21.
It will be understood that the device is capable of many modifications in structure and design, without departing from the spirit of the invention, within the scope of the appended claim.
plug 2l freely to permit removal of the reservoir a Having thus described my invention, what I claim and desire to secure by Letters vPatent of the United States, is:
A brush of the class described, comprising `a head having a centrally arranged passageway
