FOUNTAIN LATHER BRUSH.

Application filed March 2, 1921. Serial No. 448,984.

To all whom t may concern.'

Be it known that I, GEORGE G. FLOYD, a citizen of the United States, residing at Riverside, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Fountain Lather Brushes, of which the following is a specification.

My invention relates to fountain brushes in general, but concerns more particularly, although not restrictedly, brushes of this general type designed for the application of lather preliminary to a shaving operation.

To this end, the supply of soap or shaving cream is contained in the handle' of the brush and is delivered in small quantities as occasion requires to the bristles of the brush, ready for the formation of the lather.

One object of the invention is to be able to use a collapsible rsupply tube whereby the soap or cream is always maintained in a cleanly and sanitary manner until actually used.

A further purpose of the invention is the employment of a suitable valve to control the discharge or deliveryr of the soap or cream to the brush and to prevent an unintentional feed thereof to the brush.

Another salient characteristic of the appliance embodying the invention is the employment of means to assure the collapse of the compressible supplyv tube without increasing any of its transverse dimensions, or, differently stated, confining the width of the collapsed portion of the tube so as not to exceed its original diameter. y

An additional outstanding feature of the invention resides in anim )roved cover for` the brush which may be app ied and removed with facility and dispatch and which permits the brush to stand with its bristles disposed downward to aid their draining and drying.

In order that those skilled in this art may have a full and complete understandving of the manner in which the foregoing and other desirable advantages ofthe invention are obtained in a structure embody-rA ing the invention in question, have illustrated in the accompanying drawing a preferred and desirableV embodiment of such invention, like reference characters throughout the several views applying to the same parts.

In this drawing: Y y

Figure 1 is an'elevation of the complete fountain brush with the bristle cover in position; f

Figure 2 .shows the same with the cover removed illustrating the brush portion proper; v

Figure 3 is a'fragmentary central longitudinal section through the appliance with theA brush cover removed g Figure 4 is a horizontal section on line --l of Figure 3; and

Figure 5 is a plan view of the rider or bridle employed in connection with the collapsible supply tube.

Referring to the drawing, it will be perceived that the structure comprises a sheetmetal cylindrical shell 11 open at one end and' provided at its opposite end with a circular rib 12, an adjacent external annular groove 13, and an inwardly-converging, centrally-apertured end-wall 17 fastened securely to a round supporting member 18 internally screw-threaded to detachably or removably receive the threaded neck 19 of a substantially-cylindrical, collapsible supply-l tube 21 containing a charge of soap or shaving cream. y

lSuch supply-tube is intended to be concealed or housed in a cylindrical sheet-metal cover 15, having an inturned edge portion at `1d, and longitudinally slit at a plurality of points at 16 to give the open end of the cover a degree of elasticity, whereby it may be sprung over the bead or rib 12 and detachably held inV position by the part 14 fitting inthe groove 18 behind the rib.

The two parts 17 and 18 may be rmost conveniently secured together by fitting a reduced portionof the latter in the central hole of they former,r and then upsetting such part asis fully depicted in Figure 3.

Element 18 also has a threaded aperture 22 receiving the corresponding threaded terminal part of' a tube or pipe 23 and holding the longitudinal passage through the same 'in register with the mouth tof the supply-tube. l

The upper or outer end of such tube or pipe is closed, but it has two lateral apertures 211 through which the soap or cream may be expressed into the centraly portionof the brush, the tube or pipe having an enlarged head 25 with a central groove 26 for the application of a screw-driver when the pipe is applied to or removed Vfrom the member 18.

A brush head or base element 27 has a round part adapted to fit and slide in the shell 11, an enlarged hollow rib 28, and an inturned portion 29 designed to firmly grip and hold the base portions of the bristles of the brush.

Internally the member 27 accommodates a sheet-metal element having a cylindrical portion 32 fastened to the inner face of the part 27, an intermediate disc portion 31, and a Vvalve sleeve 33 fitting over and adapted to slide on the pipe or tube 23 to open and close the valve ports or openings 24.

The brush proper 34 is composed of suit able bristles whose inner ends are securely held between the parts 27, 28 and 29 and th( valve sleeve 33, whereby the latter and the brush are fastened together and are adapted to move in and out as a unit.

To normally maintain the brush inV projected position and the valve ports closed, a coil-spring 35 is interposed between the elements 17 and 31, surrounding the support 18.

In order to prevent the collapsible supplytube 21 from expanding or enlarging in any direction when it is squeezed to deliver a portion of its contents through the delivery pipe 23, it is equipped with a tapered conflning rider or bridle 36 constructed of a band of liexible sheet-metal, one end of which has a slot 37 therethrough for the ren ception of a tongue 38 on the other end of the band, the tongue or lip 38 being' bent back after passing outwardly through theY slot to hold the ends of the band togetherV adjustably and to give the rider a definite size conforming to that of the tube with which it is used and around which it is fitted as shown. p

Internally, the confining rider has two, opposite, longitudinally-tapered, hollow ribs 39, 39, made of suitably-shaped sheetmetal members having top and bottom tongues or lips 41 and 42 bent over the corresponding edges of the element 3G to hold or maintain the ribs in position.

The open-ended cover 42 for the bristle portion of the brush comprises two, sheetc metal substantially semi-cylindrical shell v elements 43 and 44 hinged together at 47'by an eyelet passing through overlapped ears 45 and 46, the cover near one end having a hollow bead 48` adapted tol fit over the annular/rib 28 of the brush, with the portion 49 of the cover between such riband the shell 11. y

At such end of the cover, the one element 44 has ears 51 on its opposite sides overlapping the companion element of the cover and provided with indentations 52 forming internal bosses adapted to fit in recesses of the parts which they overlie.

' The other ory outer end ofthe cover is flat and open, the'edges of the two parts do not touch in the contracted or closed condition of the cover lleaving longitudinal openings style of brush occurs practically as follows:

The rider or bridle 36 is clamped around the lower portion of a soap or cream supplytube 21 and forced part way along the same towards its neck to provide substantial ex- Y ternal grooves in the tube by the ribs 39.

Such infolding of the thin metal at these two opposite points assures that when the tube beyond or below the rider is squeezed or collapsed to expel its contents, the tube will not expand sidewise beyond the original diameter of the tube. Y

This permits the employment of a cover over the tube not much larger in diameter than the tube itself.

The supply-tube having thus been fitted with the groove-producing or metal-folding band or strap, the neck of the tube 19 is screwed into the threaded socket in the supporting member 18. Y

To feed some of the soap or cream to the bristles, the brush 34 and its head or base are pushed inwardly with one hand causing the valve sleeve 33 to open the valve ports or apertures 24, and at the same time with his other hand'the operator squeezes orcompresses that part of the tubev below or beyond the rider, thereby expelling into the brush proper any desired quantity of the tubes contents.

As soon as this hasbeen accomplished, the brush is released and the valveiimmediately closes automatically, thus effectually preventing any further discharge of the soap or cream, which sometimes tends to occur with collapsible tubes of this character. i

Thereupon, the cover or handle part V15 may or may not be attached to the appli` ance over the tube and the brush structure as a whole employed in the usual way, although some persons preferto omit the application of the handle cover and to use the supply tube itself as a handle.

From timey to time` as occasion requires,

the bridle or'rider 36 is forced along the tubev to preliminarily form the side grooves or deformations in the tube before the latten is collapsed or compressed to feed its contents. Y f

The use of the brush having beenY completed and its bristles having been"'washed or rinsed to remove the surplus lather as is customary, the hinged cover is applied over the ,brush by turning its hinged sections together over the bristles, thus more or less automatically compressing the brush which has a natural tendency to expand. The complementary parts of such cover 4are held in this closed relation by the cooperating catches or locks52 and the presence of a portion of such cover betweenthe bead 28 and the end of the shell 1l prevents the inward movement of the brush and consequently prevents the opening of the soap or cream supply valve.

Accordingly there is no danger of a discharge of the contents of the tube so long as the bristle cover is in place.

If any of the bristles tend to project through the slits or cracks in the cover, they can be easily withdrawn therefrom by merely turning the cover somewhat on its own axis.

Inasmuch as the end of the cover is positioned slightly beyond the ends of the bristles, is open, and is flat, the whole struc ture may be caused to stand on such open.

end thus facilitating draining of the wet or damp bristles.

Those skilled in this art will readily understand that the invention is not limited and restricted to the precise structure shown and described since radical changes may be made in the same without departure from the substance and essence of the invention and without the sacrifice of any of its substantial benefits and advantages, and it will be furthermore understood that the brush itself is not confined to the particular use specified since it is capable of satisfactory employment in many relations.

The collapsed or flattened part of a supply tube of the type indicated is of a width ordinarily more than one and one-half times the original diameter of the tube, and one purpose and function of the progressivelyadvanced rider or confiner is to prevent such sidewise expansion during the flattening of the tube. In the present embodiment of the invention the width of the collapsed part of the tube is confined or restricted to the original diameter of the tube, but, of course, reasonable variations are permissible.
