Fig. ll is a perspective view of the brushguard.

For the purpose of illustrating the present invention, the description below relates to a fountain-type dispensing device which is adapted to dispense a cosmetic such as, for example, a nail polish o-r lacquer., but .it will be understood that the present embodiment of the invention -is -by way of illustration only and that the device be used for dispensing other liquid or semiliquid mediums as. for example, mucilage, paint and the like. Referring to the drawings, the cosmetic-dispensing device embodies a barrel indicated generally at I5 and comprising a cylindrical tubular-member consisting preferably of metal, although a suitable plastic material may be used, and having a plurality of external screw threads I6 at its forward end, the threadsv being terminated rearwardly on the forward end of the barrel by an annular relief-recess il. The forward end of the barrel I5 has an end-closure or end wall I8 provided with an axial aperture I9 communicating with the front and rear faces' 29 and 2I respectively of the end wall I 3, the sides of the aperture I9 converging slightly from the outer face 2U to the inner face 2i of the end wall i8. The cuter face 2B of the barrel is shown as a shallow countersink, but may be a planar surface at substantially right angles to the longitudinal axis of the barrel, whereas the inner face 2I of the end wall I8 constitutes a relatively-deep frusto-conical countersink, the forward end of which intersects the rear end of the aperture I 9, and the rear edge of which intersects the forward end of the substantially-cylindrical vbore 22 of the barrel. The diameter of the internal bore 22 of the barrel is substantially uniform from its forward end rearwardly to a point substantially one-third the overall length of the bore 22, as indicated by the annular shoulder 22a, the diameter of the bore rearwardly of the shoulder 22a being slightly larger, for the purpose hereinafter described. The rear end of the barrel I5 is provided with an external helical screw thread Z3 having a relatively-steep pitch, the threads being coarse and substantially rectangular in cross section. The rear end of the barrel is adapted to be closed by an apertured disk-shaped plug 24 which in the present embodiment seats against the shoulder 25 of a counterbore 26, theplug 24 being held securely on its seat by an annular flange 21 spun over the outer edge of the rear face of the plug 24. The latter is a preferred construction but it willbe understood that any other equivalent means may be used for securing the plug 24 in the counterbore 26 at the rear end of the barrel. The aperture 28 of the plug 24 is adapted to support a bushing 29 having a cylindrical bore of uniform diameter and comprising an external shank-portion 30 and a stem-portion 3I of reduced diameter, the latter being adapted to t tightly in the aperture 28 of the plug 24. The rear end of the stem-portion 3I of the bushing is shown peened over the annular rim of the plug-aperture 28 and is adapted thereby to effectively hold the front face of the plug 24 tightly against theannular shoulder 32 at the lower end of the shank-portion 30 of the bushing. In accordance with the aforesaid construction, al1 joints between the plug 24, the barrelcounterbore 26 and the bushing 29 are effectively sealed so as to preclude any leakage therebetween, the plug and bushing-assembly constituting an apertured end-closure or bottom for the rear end of the barrel. l

Mounted on and arranged to slide freely along the barrel I5 is a cylindrical sleeve 33, the forward end of which is provided with a relativelyshort substantially-longitudinal indenture constituting a spline 34 adapted to engage in a longitudinal groove 35 formed in the outer surface of the barrel (see Figs. l, 3 and 4), to prevent rotation of the sleeve relative to the barrel, the longitudinal barrel-groove 35 extending uninterruptedly from the rear end of the barrel forwardly to the relief-recess I'I. The rear end Vof the sleeve 33 is upset to provide a cylindrical cuff -portion 36 of substantially uniform diameter and having relatively-thin walls, the internal diameter of the cuff being substantially equal to the outside diameter of the sleeve. In the present embodiment, the cuff is formed as an integral extension of the rear end of the sleeve and in a manner such that the rear end of the sleeve forms an annular internal shoulder 37 at the forward end of the cuff.

The cuff-portion 36 of the sleeve is adapted to rotatably support the forward end of a substantially cylindrical applicator manipulating means indicated generally at 38.l The latter comprises a cylindrical thimble or finger-piece 39 of relatively-thin wall section, the forward end of which is characterized by a rim-portion 40 of relatively-thick cross section hereinafter referred tov as a retaining-band, the thickness of the latter corresponding substantially to the thickness Aof the body-portion of the sleeve. The outside diameter of the retaining-band 40 is substantially equal to the inside diameter of the cuff 36 of the sleeve whereby the retainingband portion of the Alnger-piece is adapted to be assembled in the cuff and to have a close rotatable t therein, the forward end of the linger-piece being in abutting relationship with the shoulder 3'I of the sleeve. The finger-piece 39 is adapted to be retained in its assembled position in the cuff by spinning over the rear end of the latter beneath the annular shoulder 4I of the retaining-band 40. The applicatormanipulating means 38 is thus held from moving longitudinally with respect to the sleeve 33 but is enabled'to rotate freely in the cuff-portion 36 thereof. The rear end of the finger-piece 39 is provided with a substantially-solid head 42. the outside diameter of which corresponds substantially to the outside diameter of the barrel I5, for the purpose hereinafter described, the head being provided with a finger-grip comprising an annular flange 43 which is hexagonal in shape so as to provide a plurality of flat surfaces 44 adapted to prevent the device'from rolling when placed on a flat surface or the like. The forward end of the linger-piece 39 is provided with an internal screw thread 45 corresponding in size and pitch to the screw thread at the rear end of the barrel, the screw thread 45 being adapted to engage the screw thread 23 at the rear end of the barrel to advance and retract the sleeve relative to the barrel, as hereinafter described.

The head 42 is provided preferably with a substantially-flat end 46 for temporarily supporting the device in an upright position on a table-top, chair-arm or the like', and has an axial aperture 41 adapted to receive and support a rod 43, the rear end of which is secured in the aperture 4T of thekhead 42 vby fastening-means comprising a pilot-screw 49 and lock-screw 5I), both of which aalnalja bore-of.:.th bushing 'zralthoughipermittingf the bushing-.to slideilongitudi'nally'orrthero'drASs: zThe rear .vendor bottom of ithezbarrel is 'thussupporte-dl and rgui'de'dl' byfthe; rodi 48 f for'. :longitudinal movement in tne;rearend oflt'he sleeve'ian'dlin the forwardzendor'lingerie-piece; 39::'of`i1he applicator# malnipulatinglmeansei38, the,internal diameters: of the-:sleeve andlngerepiecefbeing: equal, so: asfto provide' :a continuousxboref of. uniform :'diametei'.; It will hemlear: that zthe:reart endzsofith'egbarrel is efectivelynclosedaby"the plug,1.,.bu'shin`g andirde assembly,Y as .ai consequenceof'whichLithel internal i bore 22. of thetbarrelf constitutes aV cavityclo's'ed at :on'eiend and .capableiof retaining 2a' liquidbm'e-l dium: .The' 'barrel-bore' T22-I is; ,th'eref'ore, hereinafter. referred-.toras.the*fbarrelereservoirior-ffreservoirj;v l Secured to orrformedaintegrally onine-'forward end of .1:l1e1.ro'd'=48lis .amrenlarged substantially frusta-1conicallyshaped-head53 vvhichicon'stitutesA a valvee'headxorluclosing; oith'e aperturef-l-'S in theiforwardlendof thefbarrel; :as hereinafter-2described.y x A1 longitudinal aperture: 5411s drilledllor otherwise' formed axiallyl'in .the .forward endgcf theerodfASand-iits valve=headi53 tol'accommodate theferrule of an applicator Whichfintherpresent: embodiment, comprisesl a. `brush-P56Y Itawill .be/ understood; however.;thatrapplicatcrsvof 'varia ous iormsllmaylbe us'edf-- Th'e`. fer-rulefli off-.the

InZ this of: the barrel, the cap is adapted to be slipped over the rear end 112 of the linger-piece 39 (which is of'corresponding diameter) when the device is in use, as indicated in Fig. 6.

At this point, it vmay be pointed out that the several elements constituting the applicator of this invention are adapted to take several different positions relative to each other in carrying out the several functions of the device. Figs. 1 and 2 of the drawings illustrate the device when it is capped and tightly sealed for transportation, the elements being in the relationship shown in Fig. 2, which is hereinafter referred to as the "carrying position of the device; Fig. 5 shows the related positions of the elements after the cap has been removed from the forward end of the barrel, the device being hereinafter referred to as being in its normal position. Fig. 6 shows therelated positions of the elements ofthe device when the brush has been advanced for use, the device being hereinafterreferred to as being in its operating position and Fig. 7 shows .the related elements of the device in the position for introducing a liquid into the reservoir and for filling the brush, which position is hereinafter referred to as the charging position of the device. .The operation of the device may be described briefly as follows:

Assuming that the cap 'l has been threaded onto the forward end of the barrel, as shown in Figs. l and 2, so as to seat its stopper l2 in the aperture I9 in the end wall of the barrel, in so doing, the rear end Mof the cap' will have engaged the forward end of the sleeve 33 and-displaced the latter longitudinally rearwardly on the vbarrel l5 to the position shown in Fig. 2 corresponding to its carrying position and in so doing'will have retracted the applicator-manipulating means 3S, together with the rod 48, brush 56 and brush-guard 58, into the body of the reservoir 22 against the force of the compressed spring 69, in which position the brush and brush-guard are Withdrawn out of the aperture I9 in the end of the barrel, the latter being completely sealed by the stopper T2. With the elements of the applicator in this assembled relationship, the applicator is adapted to be carried successfully in :a ladys pocketbook, handbag or the like, without fear of leakage.

It will be appreciated, however, that before it is possible to vdisplace the sleeve and its attached brush-manipulating means longitudinally rearwardly relative to the barrel, the threads 45 Vof the finger-piece 39 must have been disengaged previously from the threads 23 of the barrel .by rotating the finger-piece 39 relative to the barrel, inacounterclockwise direction, which is the direction of rotation of the finger-piece forretracting the brush into the reservoir off the barrel.

On displacing lthe brush-manipulating means rearwardly longitudinally relative to the barrel', the threads of the finger-piece 39 will be carried out of engagement with thek threads of the barrel l5, as a consequence of which the brushrnanipulating means is temporarily disabled so that in the event its finger-piece 39 lshould be rotated while the cap 'I0 is in place,the brush would not bemovcd forwardly against its stopper 12, thereby precluding damage from this `caus'e,". the1brush,. brush-guard and brush-mal0 is unscrewed, the gradual forward movement of the cap relative to the barrel permits'the spring-loaded brush, brush-manipulating means and sleeve to move forwardly until the leading thread of the cap engages the rearmost thread of the barrel, at which time the head 66 of the brush-guard will engage or be in close proximity to the countersink 2l in the end wall I8 of the barrel, at which time the cap has been disengagedand vwithdrawn from the forward end of. thebarrel. The elements of the applicator are now in their normal position, as shown in Fig. 5, in which position the threads of the finger-piece 39 are in a position to engage the threads of the barrel l5 so that by rotating the finger-piece 39 in a clockwise direction, the brush, brush-supporting rod and valve-head will be moved forwardly longitudinally into operating position, as shown in Fig.4 6. As pointed out above, when the cap 'I0 is off and the elements are in their normal position of Fig. 5, proximity-of the guard-head' to the end wall i8 reduces the effective size ofVL its aperture I9. Moreover, with the brush in its retracted position with respect to the guard, the brush is embraced by and substantially lls the aperture El inthe head of the guard, as a consequence of which evaporation of liquid from the reservoir 22 is appreciably reduced. Itwill be understood, however, that if the device were inverted, liquid within the reservoir would seep through the bristles of the brush and form drops `at the end thereof. However, when 4the device is ready for usefas shown in Fig. 6, the brush 55 will have been ,advancedA out of the aperture 6l of the brush-guardby rotating the finger-piece 39 in a clockwise direction, and vthe guard-head 66 and valve-head 53 of the rod S8-will have been brought into tight engagement with the counterbore 2l of the end wall f8 and the valve-seat 68 f of the applicator-guard respectively, so as to effectively close off the open end of the reservoir. Consequently, wheninverted and in use, liquid is positively prevented from escaping from the aperture i9 in .the forwardend of the reservoir. Assuming now thatthe device has been used until the liquid contained in the brush has been eX- hausted, then to bleed more liquid to the brush, it is only necessary to rotate the finger-piece 39 in a ccunterclockwise direction sufficiently to unseat the valve-head 53 of the brush-supporting rod from the valve-seat 68 of the brush-guard,

to permit a small quantity of liquid to flow from the reservoir 22 out of the aperture S7 of the guard-head and onto the brush, the amount of liquid` which flows to the brush being regulated bycontrolling the size of the opening allowed between the valve-head and its valve-seat. Upon obtaining a suihcient amount of liquid in the brush, the `finger-piece 39 maybe rotated again ina clockwise direction to close the valve against its seat topreventadditional liquid from flowing to the brush.

In some instances itmay be desirable to charge the brush with a large amountof liquid.. In this event, the finger-piece 39 is rotated in a counterclockwise direction sufficiently to 1 retract the brush into the brush-guard and'to disengage the threads of the Ylinger-piece from the threads of agcriars .v9 the barrel, 'after' -which the' ringer-piece, includving the -rod;'=-brush, brush-guardand-fsleeve vmay bedrawn rearwardly` longitudinallyy on the barrel so as -to-y immerse the sbrushand brushguard assembly inthe liquid ofthe-reservoir, as shown in Fig. 7.? Thereafter, the ringer-piece may-be moved forward-ly longitudinally 4rela-tive -to the barrel to Vre-en'g'age its -threads'with -the threads of the barrel and subsequently rotated clockwise to advance the-'brush outof-theforward end ofthe barrel. Thespeed'at which'the brush is advanced out ofthe aperture of -the' guard will determine to Vsome degree the'amount'of` liquid which'will `loe-retained in the brush.'l Thus, if the brush is 'advanced rapidly,` ythen a large amount of Vliquid will be retained within the brush, whereas, if Vthe brush is advanced slowly, a large proportion of the '-liquidwill"drain V'off' of the 'brush 4back; into the reservoir. Varying `the speed at which the brush isadvancedV from "the reservoir has, therefore, substantiallythe same eiect as wiping the'brush tofremoveiexcess `material therefrom.

As an additional `feature of the invention; it will be noted that when Athe device is in its operating position as showninFigr, the guardhead v-Bi and valve-head' 53' 'effectively '.close" the rear end of the aperture I9 'in the forward end of the barrel so that the `forrnerconstitutes, in effect, a shallow cupeshaped'pocket or reservoir at-the base of the brush.V .Intheevent a" large amount of'liquid is contained in the brush by the charging action described above, then this excess'material may drain back into the overflow reservoirat the base of the brush and supply the brush with the liquid as it isneeded.

Referring to Figs. 8, 9'and 10, the invention also embodies a safety featureadapted tominimizeA thelikelihood of improperly assembling the capon the -barrelin such away as toallow the liquid therein to leak out. vTo this end, the'barrel is provided withan index-mark constituting a shallow recessed groove 15 which may be colored with a suitable paint or lacquer, the forward edge 16 of the index-mark beinglocated on the barrel at adistance from the threads at the base thereof such that 'when-the trailing edge 18. of the 'rearmost'thread23 of the barrel rides on the leading edge 19 of the foremost thread 45 of the brush-manipulating means, as indicated in'Fig. 8, the sleeve will have-been displaced rearwardly on the barrel a distancev vcorresponding substantiallyto' the distance'between the rear end 14 of the cap and the 'rearmost thread in the forward end-thereof. In this position of the brushmanipulating means 38, the 'forward edge '16' of the index-mark will show as a narrow colored linetwhich'indicates that the threads o'f the cap may catch the threads -at the` forward end of the barrel, so that the cap-may be successfully screwed thereon, in themanner'pointed out above. Inthe event, however, that the brush-manipulating Ameans were not rotated 'counterclockwise suiciently to uncover the forward edge 16 of the index=mark, the distance from the forward edge of the sleeve to the threads at the forward end `of the barrel would be less than the distance between the rearmost thread of the cap and its rear edge 14, as a consequence of which'the cap could not 'be threaded onto the barrel. Hence, the relatively-narrow color-band which Will be revealed /when the brush-manipulating means has been displaced rearwardly sufliciently to permit the cap to be threaded onto the barrel, serves to indicate the proper relationship of thebarrel, cap and 1-0 sleeve-forlsecuring the cap to the Vbarrel in leakproof relationship. Fig. Sl'showsthe` cap assem-v bled on the barrel. cap onto thev barrelfas described-above, moves the'sleeve rearwardly on'thebarrelso that there is no longer anyopportunity for-the'threads'of the brush-'manipulating' means to engage the threadsV of' the-barrel. Moreover.,4 when thev cap is fullythreaded on the lbarrel' so as` to seal the aperture I9 therein'lby its stopper 12, the'rear end 1,4 of the cap will 'be substantially'c ipposite the rear'edgel 1-1 oftthe index-mark ofthe barrel, beingv Vsuilicientlyshort thereof, :as indicated Ain Fig. 10,-to leave a-narrow colored band. This narrow band'servesto indicate thatthe cover is properly secured to' the end'of the'barrel and that thereservoir is sealedby the stopper ofthe cover.

`On the other hand, a relatively-wide index-mark or bandwoul'diindicatel that the cover was .not screwedl fully onto the barrel.

' Although'the-device described is' designedA piefn .erably for 'applying nail'polish or lacquerA 'for fingernails and to this end embodies a reservoir 1 capable ofholding'an* amount offliquid substantially Aequivalent. to the standard-fsize Acosmetic bottle, itwil'lbeunderstood that the size ofthe applicator may` vary depending `upon 'the spcic use to which it is to Ibe put, and that otherlliquid mediums may belemployed such as, Yforexam'ple, a liquid rougeflipsticlr,` or mucilage, paintsand the like.

In a device ofthe class describedin combination: a barrel having a reservoir, an apertured end Wall communicating there-with and external screw threads at opposite ends thereof; a sleeve to support said barrel, said sleeve having a telescoping connection Vtherewith for longitudinal movement with respect thereto; an applicator supported in the reservoir of said barrel; applicator-manipulating means comprising a nger-piececonnected to said applicator, said iinger-piece being rotatably connected to said sleeve and adapted tohave screw-threaded engagement with the extreme threads at the lower end of said barrel so as to be effective upon rotation in one direction to advance said applicator" through said reservoir Vout of the aperture in the end Wall of said` barrel and upon rotation in the opposite direction to retract said applicator into said reservoir; and closure-means for said device comprising a cap having a stopper, said cap being adapted to have screw-threaded engagement with l the apertured upper end orsaid barrel and to abut the forward end of said sleeve so as to be effective upon rotation in a direction to threadedly engage the apertured. end wall of said barrel to force the stopper into the aperture in the end Wall of said barrel and seal the latter and simultaneously to more said sleeve rearwardly on said barrel so as to displace said ringer-piece out of position for screw-threaded engagement with said barrel, thereby to preclude operation of said applicatar-manipulating means.

7. In a device of the class described, in combination: a barrel having a reservoir, an apertured end wall communicating therewith and external screw threads at opposite ends thereof; a sleeve to support said barrel, said sleeve having a telescoping connection therewith; a spline interconnecting said barrel and said sleeve to permit longitudinal movement only of said sleeve relative to said barrel; an applicator supported in said reservoir; applicator-manipulating means comprising a finger-piece rotatably connected to said sleeve and adapted to have threaded engagement with the external threads at the lower end of said barrel; a rod secured at its rear end to said finger-piece and extending forwardly through said reservoir, said rod having an aperture in its forward end to removably support said applicator; an applicator-embracing guard slidably mounted on the forward end of said rod; a barrel-bushing in the -bottom of said reservoir and mounted on the rear end of said rod to slidably support the inner end of said barrel; and resilient-means carried on said rod arranged to engage at its forward end against said applicatorembracing guard and at its rear end against the barrel-bushing of the reservoir to urge said guard into engagement with the apertured end Wall of said barrel whereby said guard is adapted to partially close the latter and in cooperation with the embraced applicator to minimize evaporation of liquid from said reservoir, said resilient means being adapted also to urge the finger-piece into position for threaded engagement with the external threads at the lower end of said barrel whereby rotation of the finger-piece in one direction effects the retraction of said barrel rearwardly relative to said sleeve to project said applicator through said guard and out of the aperture in the end wall of said barrel.

8. In a device of the class described, in combination: a barrel having a reservoir, an apertured end Iwall communicating therewith and external screw threads at opposite ends thereof; a sleeve to support said barrel, said sleeve having a telescoping connection therewith; a spline interconnecting said barrel and said sleeve to permit longitudinal movement only of said sleeve relative to said barrel; an applicator supported in said reservoir; applicator-manipulating means comprising a finger-piece rotatably connected to said sleeve and adapted to have threaded engagement with the external threads at the lower end of said barrel; a rod secured at its rear end to said finger-piece end extending forwardly through said reservoir, said rod having an aperture in its forward end to removably support said applicator; an applicator-guard slidably mounted on the forward end of said rod; a barrel-bushing in the bottom of said reservoir mounted on the 14 rear end of said rod to slidably support the inner end of said barrel; resilient-means carried on said rod arranged to engage at its forward end against said guard and at its rear end against the barrel-bushing of the reservoir normally to urge said guard intoengagement with the apertured end Wall of said barrel whereby said guard is adapted to partially close the latter so as to prevent evaporation of liquid from said reservoir, said resilient means being adapted also to urge the finger-piece into position for threaded engagement with the external threads at the lower end of said barrel whereby rotation of said nger-piece in one direction effects the retraction of said barrel rearwardly relative to said sleeve to project said applicator through said guard and out of the aperture in the end wall of said barrel; and closure-means for said device comprising a cap adapted to close the aperture in the end wall of said barrel, said cap being adapted to have screw-threaded engagement with the apertured upper end of said barrel and to abut the forward end of said sleeve so as to be effective upon rotation in a direction to threadedly engage the apertured end wall of said barrel to move said sleeve rearwardly relative to said barrel and thereby to displace said applicator-manipulating fingerpiece out of position for threaded engagement with said barrel.
