'ments in Soap-Feeding Shaving-Brushes;

and I do declare the following tobe a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i

This invention relates to fountain brushes,

I and more especially for those intended for shaving; and the object of the same is to produce a shaving brush having a soapreservoir in its handle, and between the handle and bristles an automatically operating check valve which will permit the expulsion of just one charge of shaving soap when the handle is squeezed. This object is accomplished by the construction hereinafter more fully described and claimed and as shown in the drawingswherein- Figure 1 is a side elevation of this improved brush; Fig. 2 is a central longitudinal section thereof, slightly enlarged; Fig. 3 is a cross section on the line 3 3 of Fig. 2; Figs. -4t and 5 are perspective' details of parts of the checkl valve. Inthe drawings the let-ter B designates the bristles of an ordinary shaving brush having a hollow handle H secured to the base of said bristles by a ferruleF, and the letter R designates a reservoir within the handle and in which in the present instance I propose to store liquid soap. The gist of the present invention lies in the construction of. parts whereby the reservoir may be charged with soap, and whereby when the latter is fed to and through the bristles only a limited amount will be ejected by pressure upon the bulb or reservoir R.

Coming now more particularly to the present invention, the hollow handle H 1s provided at one side with an opening 1 large enough to admit a fingerwhen pressure is to be applied to the rubber bulb R Y' 56 which forms the reservoir adapted to contain liquid soap. This reservoir is located within and rather closely tits the interiorof the handle H, and in its upper end is mounted an externally threaded nipple 2 which projects through a tubular boss 1 formed at this end-of the handle and has perforations 3 in its outer end located oi its axis, and a central plug 4a projecting outward.V Screwed o nto the latter 1s a cap 4 having a perforation through its axis,l and when this cap is screwed down tight its perforation is out of.

alinement with those in the nipple and is closed by said plug, but when it is unscrewed all perforations are open and thereservoir may be filled therethrough in a Amanner .which will be clear. The other end or neck of this bulb being closed, it will be obvious f thatif the cap is removed, the nipple ini serted into liquid soap,l and the bulbpressed upon as above described, when the pressure is released the suction set up by the opening out of the bulb.will draw in liquid soap sulicient to fill the reservoir. `Thereafter the .cap is reapplied and the parts are ready for use;

It Will be noted that the screw cap when screwed down onto the threaded end of the nipple contacts with the outer extremity of the boss 1 so that these parts are held closely together and the outer end of the reservoir R is held Within the outer end of the hollow or bulb-shaped handle H. This feat-ure of construction I consider of advantage because it prevents the displacement of the reservoir when compressed by the finger, either for ejecting the liquid therefrom through the measuring valve or for sucking in the charge of liquid through the nipple.

Between the neck 5 of the bulb and the base 6 of the brush is disposed my improved check valve which is by' preference constructed as follows: The lower member? is inserted within the base 6 and internally threadedlat its upper end as at 8, its lower end 9 being preferably contracted into an outlet along the axis of the bristles B. The upper member 1() is cylindrical and smooth Iinside and outside excepting for a surrounding bead 11 at its up er4 end over which the neck 5 of the bulb R 1s slipped and engaged; but the lower end of this member has an external flange 12 opposite which is an internal shoulder 13, and below said shoulder the entire member is reduced as at 14 and externally threaded lto engage the threads 8 of the lower member. The two members are ,shown screwed together in Fig. 2, the end face of the flange 12 being in contact with the upper extremity of the lower member so lthat the entire casing of the check valve stands along the axis of'this brush and its handle. ,tion 14 of the upper member forms one valve The lower end of the reduced porseat, and the shoulder 13 inM this member A. forms another; and through the bore or the lowermember 7 and holds the valve accurately upon lits seat.

The upper end of the stem is threaded as at 19 and engaged by a'nut 20 which is by preference formed integral with an upper valve 21,` an uppermost spider 22 serving as a jam nut to hold the nut audits valve after they have been adjusted upon the threaded stem. Finally an expansive coiled spring lower end resting upon the shoulder 13 and its upper end resting beneath the spider 22, and its expansive force tending to keep the lower valve 17 closed upon its seat. As clearly shown the lower` flanged section of the tubular member 7'isl embedded` in the confined upper ends of the bristles B and,

' further,by the employment of the contracted to' the bulb forming end of the said member,A the bristles are spread and securely held within the handle.

`llVit-h this construction of parts, the operation of my improved device is asfollows: The reservoir having been lled inthe manner above described, when the user desires to eject some of thevsoap for the purpose of A lathering his face,- 'Y

pressure 1s applied 1 in the hollow handle the yreservoir R. The liquid soap therein iiowing past the spider 22 and valve 21 and through the bore 15, un-

through the opening seats the valve 17 from its seat against the expansive tendency of the spring, and is ejected through the outlet 9 into and along the bristles B; the force of the pressure however, causing the upper valve 21 toclose upon its seat so thatl only a limited amount vis ejected. It is quite obvious that this amount may be regulated by adjusting the nut 20 upon the threaded stem 19 so as to set it farther from or nearer tothe valve 17 (tightening up the spider 22A after adjustment) and thereafter a greater or lesser amount will flow from the. interior of the 25 is provided, its

l. l reservolr into the space between the valves to constitute the charge. The release of pressure upon the exposed portion `of the reservoir` R permits the latter to 'expand Y again, and as it does so the spring 25 again expands and the checkv valve resumes the position shown in Fig. 2 'so that its lower head 17 closes against the Aseat at the lower end of the upper member of its casing'and nothing can pass in or out of the reservoir until the latter is again compressed.

I have described my invention as applicable to a soap feeding fountain brush, but it is clear that its uses are not limited to 'that alone because with or witho-ut modifica? tion of details it-might be adapted for many other purposes. This, however, is the preferred embodiment of my idea and its preferred use; but I do not wish to be confined to the exact details of construction, nor to the sizes, shapes and proportions of mate# rials of parts.

What is claimed as new is: A

A fountain brush comprising a bulb shaped handle having a', finger opening formed therein, bristles canried by the lower end of the handle, a tubular member comA posed of two sections, a measuring'` valve located in theupper detachable section, a section forming the lower portion ofl said member and having a contracted discharge end and' an upper annular flanged end, all of which is embedded in the bristles coniined within the handle, a lexiblevbulb located within the latter with its lower end removably secured to the upper section of the tubular member, and means for detachably' closing the liilling end of the flexible bulb immediately above the valve located in the tubular member.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
