Application May 15, 1931, serial No. 537,733 21 claims. 4(o1. 13a-78.5)

This invention relates to devices involving permeation of powder or other solid particles, in operations such as dispensing, regulating, distributing, bolting, or gauging; or combinations of such operations.

A purpose of this invention is, first, to provide a novel reservoir powder puff having heretofore unobtainable advantages, such as hereinafter suggested, and, second, to extend one or more of these other new advantages to the greatest possible variety of other permeation operations.

Other objects will be in part obvious from the annexed drawing and in part' indicated from the following analysis of this invention, in which reference is made to the accompanying drawing illustrating an embodiment of my idea.

Broadly, my invention comprehends a distensible mechanism of positive action, appropriately embodied and adapted to useful operations involving permeation of particles of solid' matter, and characterized by interstices capable n of significantly variable permeability to solid particles, whose variations of permeability are effected by manipulation and are accompanied by proportionate variations in the total area enclosed or defined by the portion of the medium affected by such manipulation.

One of thepreferred embodiments of my invention is a reservoir powder puff such as shown in the accompanying drawing. In this particular device, the preferred permeation mechanism or medium is pliable and elastic, and is combined preferably with soft material such as cotton or silk, for applying the dispensed powder in the most pleasant and effective manner.

Although other permeation devices have been known, several very valuable additional advantages over the known devices are present in my improved arrangement. For example, powder puffs, although heretofore devised to hold powder and intended to dispense it, have never contained means whereby distribution could be regulated positively and evenly for any practicable `length of time, to say nothing of preventing loss of powder when the puff is not in use. Nor have any powder cans or containers been developed which, in certain operations for which my invention is useful, can dispense the powder with any comparable combination of evenness, speed, convenience, and adjustability of amount. For sifting, bolting, or grading of small particles, my invention also offers new means of especial value, by using only a single, simple, and compact screening medium capable of wide yet exact variations of permeability which are positively, quickly, and conveniently obtained.

In the accompanying drawing, Fig. 1 is a perspective view of a preferred form of a reservoir powder puff embodiment of my invention, shown with a portion cut away to reveal part of the insert and filling segment.

Fig. 2 is a perspective view of the complete puff, with filling valve shown slightly open.

Fig. 3 is a slightly enlarged sectional view taken through Fig. 2 on line 3 3.

Fig. 4 is a detailed view of` the structure of the body of the puff, showing the nature of a preferred form of `backing and of facing material attached thereto.

Fig. 5 is a perspective view of the elastic insert, with the filling segment partially attached thereto.`

The pull, as shown, is composed chiefly of two sections 1 and 2, each of which may be made up. of pile material 5 in combination with backing 8. Backing 8 consists preferably of rubber elements 6 interwoven with fabric elements 7. However, this backing might consist, especially in other embodiments, of any other appropriate materials desired, such as springs and wires or even rods, and having any other pattern, degree of porosity, proportion of elastic and nonelastic elements, manner of connection, or any other desired variation from the particular example herein shown, without departing from my invention, providing the resulting unit be distensible, contain interstices, and, under manipulation, vary in area circumscribed as the porosity of said interstices simultaneously varies. Moreover, and also within the scope of my invention, any

desired material other than the pile substance here shown, and attached in any other desired way, or merely loosely associated, may be used.

Continuing with the particular embodiment of my invention here shown, segment 4 preferably composed of elastic or distensibly pliable material, here rubber sheeting, is cemented or otherwise secured to insert 3 along edges 9, as indicated in Fig. 5 by the dotted strip 10 extending along one of said edges 9. Segment 4 is left open at both ends to form, in combination with insert 3, a valve for filling the puff with powder and at all other times to prevent passage thereof. If desired, means such as snap fasteners (not shown) may be used to keep thevalve more securely closed when not in use, and segment 4 could be fastened otherwise than as here shown, at its end. Insert 3 is also preferably ofrthin rubber sheeting, secured as by cementing to the back of o the outer end to section 11 asis done in the device shown.

As another variation within the scope of the puff form of embodiment of my invention, element 3, instead of being used as an insert, might be `used in place of section 2, thereby dispensing with the latter. In such case, element 3 might be joined to face 1 as by cementing the edges around the periphery only, thereby obviating the seam 11 of the device shown in the attached drawing.v

In the form shown, segment 4 is preferably first cemented as heretofore explained to insert 3 whereupon the latter, with the segment outside, is cemented or otherwise attached to section 2. Then sections 1 and 2,\with pile sides together, are sewed nearly around, turned inside out, finished as to sewing and slitted at the valve opening whereby with the outer end of segment 4 attached to seam lap of section 2, thereresults the finished article shown in Fig. 2. Whatever the form ofvv puff adopted, sections 1 and 2 contain spacebetween them sufficient to hold a supply of powder. It is to be noted especially that backing 8 can be so formed as to have any desired degree of porosity, preferably a negligible amount normally, that is, in the absence of manipulation intended to dispense powder. In the process of distension of this backing by manipulation or stretching, the non-elastic elements I also lengthen, yet prevent undue stretching of the unit. This lengthening of the non-elastic elements is made possible by such features as looseness of weave, twisted, knitted, or wavy structure of elements, or by decrease in cross-sectional area of the elastic elements when stretched.

It will be seen that by the arrangement of reservoir and dispensing means associated therewith, as above described, there is obtained the advantage of normal substantial impermeability of the dispensing means, due to the contraction of the elastic elements '7, whereas when the dispensing section is manipulated, the powder may pass through the interstices of the backing 8. Such passage or permeating is of course variable and dependent upon the degree of manipulation imparted and is effected in a positive manner with an even distribution of powder` The powder puff, in accordance with the above is compact, simple and of desirable appearance and positively retains the powder until it is desired to be applied. Its porosity is variable, thus suiting theneed or preference of an individual user.

While the preferred embodiment as described is in the nature of a powder puff, it will be understood that my invention comprehends many modifications, alternatives and equivalents, and all such are intended to be covered by vand included within the scope and range of the invention. Further, my invention is not limited to the foregoing terms but contemplates a wide variety, not only of different applications or embodiments but also of equivalents for any one application or embodiment, to-wit: every new and useful device or new and-useful element or combination of elements thereof, coming within the broadest purview and construction possible to the validity of the claims hereinafter appended.

Without further analysis the foregoing will so fully reveal the gist of this invention that `others can by applying current knowledge readily adapt it for various applications without omitting certain features that, from the standpoint of the prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and therefore such adaptations should and are intended t0 be comprehended Within the meaning and range of equivalency of the following claims.
