FOUNTAIN SHAVil TG BRUSH.

T0 aZZ iii/tom it may concern:

Be it known that we, lionnnr hit ZEARING. Jr, and CHARLES J. Orrnnmnxn, citizens of the United-States, residing in Phiiadelphia, Pennsylvania, have invented. a Fountain Shaving Brush, of which the following is a specification.

Our invention relates to shaving brushes, andinore particularly to improvements in that type of brush known as the fountain, and which comprises a reservoir or container fo a shaving soap in the form of a cream or the and means for discharging the lllfl'LEl'ltll from the container into the bristles of the brush.

One object of the invention is to provide a brush in which as many of the working parts as possible are permanently associated with the soap reservoir, thereby eliminating from the brush properall complicating parts tending to prevent proper cleansing and maintenance of a sanitary condition.

Another object of the invention is toprovide a novel form of container for the soap in the form oi a cartridge adapted for insert-ion in the body of the brush, said cartridge possessing oanufacturing advantages and comprising-suchelements as may necessary for discharging the contained material.

A further object is the provision of a cartridge having means for discharging the contained material such that in its operation the cartridge is destroyed, thereby. to prevent re-use as a containenfor the soap.

In the attached drawings:

Figure 1, is a transverse longitudinal section through the body of a brush and the cartridge contained thereby; f

Fig. 2, is a transverse section on the line 22, Fig. l; P g. 3, is a'section on the Fig. at, is tridge, and

ii 5, is a view in perspective of details of the piston by means of which the materialis fed from the cartridge.

With reference to the drawings, 1 indicates the tubular handle or body of the 33 ig. t

-i a view in perspective of the carline 'brush made in the present instance of sheet metal having pressed therein a thread 2' extending over the greater portion of the length ofthe handle, the latter having the bottom end 3 thereof enlarged, and said enwith the threads a of the lower portion 3 of the handle, the sleeve 6 being retained in the handle by the headed over top edge '7 of the cover.

*As clearly shown .in Fig. 1, the handle portion 1 has at the top and secured thereto in such manner asto be capable of rotation with respect to. the handle proper, a sleeve 8, there being a suitable recess in the interior of the said sleeve and at the bottom thereof for theireception of an annular extension 9 at the top ofthe'handle '1', which annular extension is formed in the present instance by turning over the upper edge of the said handle. y means of this extension 9 and the formation of the sleeve 8, the latter, while being retained at the top of the handle, is capable of free rotational movement thereon. The upper portion of the sleeve. 8 has,in the present instance pressed therein, a thread 10 by means of whicha cap 11 is secured at the top of the handle 1, said cap- 11 being in the present instance, as in the case of the other parts of thedevice, formed of sheet metal and having a thread 12 pressed in the lower portion thereofcorresponding to the threads 10 at the top of the sleeve 8. The cap 11 is also threaded at the top as designated by the numeral 13 for the receptioniof the internally threaded bristle-carrying member let.

As best shown in Fig. 2, the cap ll is apertured atthe top, this aperture being in the form of a central circularopening 15 having extending from opposite sides rectangular slots 16, 16, and similarly the bristle-carrying member 141s provided with .a central opening 17 extending upwardly into the base of the bristles themselves. The apertures 1516 of the cap element and opening 17' of the bristle-carrying member are for the reception of the upper nozzletop the said nozzle-like extension 20, from the base of which at opposite sides extend wings or lugs 21, 21;

The bod of the cartridge 19 is is preferably ma e-- of waxed paper ore the like,

and has in the interior thereof -a-,-piston or plunger 22 which has extending from the sides blades 23 which pass through the sides of the cartridge and which have secured to the outer ends thereofan'dexteriorly of-the cartridge a threaded sleeve 24:, said sleeve in the present instance being of sheet metal and having the threads therein pressed to conform with the threads of the handle 1.

The form of the piston-22 is best shown in Fig. 5, and theblades 23 are formed in the present instance by means of-a single element 25, which is secured 'in the interior of the plunger andeXtend'through slots'26, 26, in theroppiosite sides thereof. The corners of the element 25, are notched, as clean ly shown in thedrawings, and the sleeve 24 is so formed that its edges occupy the notches of the element'25, therebybeing secured in place. The upper edges of that portion of the member25 which passes through the sides ofthe cartridge-are sharpenedso'that as the piston 22 is fed upwardly in the cartridge by means hereinafter to be described, these edges cut the sides of the cartridge 19, as illustrated in Fig. 1. To assist in the rupturing of the cartridge, the latter may be "scored on the line traveled by the blades.

As shown in Fig. '1, it is preferred to place a disk '27 -of a comparatively soft ma terial such as fibre or felt at the top of the piston 22, thereby preventing the passage of any of the contained material past the edges of the piston and its subsequent escape'through the'slits in the side ofthe'cartridge. The cartridge 19 fits within the handle 1, as clearlyillustrated in Fig. 1, the ex tension, 20 passing upwardly through the openings 15 and 17 in the cap and bristlecarrying member respectively and having its upper end in which there is an aperture 28 established atthe base of the bristles-29, the wings 21, 21, passing through the slots 16, 16, of the aperture 15, and thereby effectively preventing th'eiturnin'g ofthe cartridge 19 in the hand-1e. v

The operation'ofjthegdevice is as'fol'lows: A full cartridge is established "as shown and described theiinterior of the handle '1 and the cover ascrewed into placewhereby the cartridge {is confined. When it -is desired to di-schar e soap from the-cartridge into the 'kbase oft e bristles, the sleeve 8 or the brushscarrying element 1a is gripped with one hand and the handle 1 rotated with the other, the result being thatfthe sleeve 2 1 the threads of which engage "the "threads of the handle l-is fed upwardly in the handle idgther- WEith the" piston "'22 in the o'l expelling a portion of the contained material "into'the base of the bristles. When the piston 22 finally reaches the top of'the cartridge 19,. the cap 11-with its associated ,parts is unscrewed from the top of the sleeve 8, after which the expended cartridge :19 may he easily removed through the top of the casing, a new cartridge being inserted inithe usual manner.

It will be noticed that none of the working parts of this device which come in contact with the soap, with the exceptionof the bristles-themselves, is connected with the brush itself, these parts being associated with and forminga part'proper of the cartridge 19. As a consequence, none ofsthe parts of the brush is contaminated bythe soap, and cleanliness is insured. :This natural cleanliness is :materially assisted --b y the construction of the brush, which provides for the separation from the handle. of the brush-carrying member 14,1and-for the removal of the cap 'lland the covert, thereby leaving the body 1 in the form of an open-ended tube, the cleaning of which isan easy matter.' The device has the further great advantage of providing apartridge which is destroyed inuse, therebypre' venting its being refilled with a soapiother than that originally contained.

We have described 'OUF'JIIVGIltlOIl in its preferred form, but it will be understood that considerable modification of the device is possible with no departure from the' essential featuresof the invention.
