2Claims.

V This invention relates to shaving brushes of the self-feeding type in which the supply-of soap is within the brush holder and charges of soap are discharged into the brush when desired to be used in latherin'g.

Among the objections to those heretofore proposed are, projecting parts; uncertainty in operation; difficulties in re-e-harging; and multiplicity of parts and complicated character of the same. The object of this invention is to provide an improved combined shaving brush and soap holder made of a few parts and which maybe made of plastic, and which will be simple in construction and operation, at the same time providing means for facilitating the filling, and for completely discharging the soap supply.

The invention consists in a hollow cylindrical body member internally :screwthreaded to which a brush holding cap-is secured by a combining member, which member presses against the base ,of the brush to press it in position against the inner part of the cap, the cap having an external diameter equal to that of the body portion and having an internal'diame'terand internal threads of the same diameter and pitch as those of the body member, with the combining member having external threads along a length of the member, about one half engaging the threads of the cap, and about the other half engaging the threads of the body portion, and with a hollow finger engaging thimble having external threadsengag-ing the internal threads of the body portion, with the internal contour of the thimble and the internal contour of the combining member preferably in conformity, whereby with these four parts, the

shaving brush with it hardened base with a central bore is held within the cap with the bristles protruding out of the same. The combining member has a bored nozzle to pass through the bore of the base of the brush. A slight rotation of the thimble discharges a charge of soap from the body portion, through the nozzle into the brush in the central part of the bristles from which it is distributed during the lathe-ring process.

The invention will be further described in connection with an embodiment of the same, as shown in the drawings; and will 'be finally set forth in the claims.

In the accompanying drawings,

Fig. 1 is a central vertical section of the improved combined brush and soap holder;

Fig. ,2 is .a spaced view 01. the parts;

Fig. .3 is a section like Fig. 11 without the brush and showing the thimble at the end Of its run;

Fig. '4 is a detail view showing the body mom, her and the thimble at the end of its run, to show the manner of removing the spindle, and v,

Fig. is a detail enlarged sectional view to show the manner of combining the body member and th brush holding member, by the combining member, the external and internal Stirfaces being identical and in alignment with each other.

Referring to the drawings and more particularly to Figs. 1 and 2, the cylindrical body member 1'0 is preferably smooth at its exterior, and is screwthreaded at its interior, as shown by lil, throughout its interior length.' A brush holding member or cap I? has a smoothexterior, preferabl-y, and is screwthreaded at its interior, as shown by l3, from its open end-up to a point 13a The outer diameter of the body member "l0 and theouter diameter of the cap member 12 is identical. The pitch :of the interior screwthreads if and of 13, are identical.

Within these members and 12 which abut each other at 1'4, there is a combinin member l5, scre-wthreaded at its exterior to match the common screws/threads of both members lil and I2, and which combines the members together. This combining member 15 has a soap receiving and guiding interior surface I 6 leading to a centrai bore 17 for the passage of the soap to the brush, at its -lower side, and has -a substantially flat upper surface F8 for the seating of the hardened end base which hold the bristles together, and also has aynoz'zle-like-extens'ion it having a bore 20 in continuation withthe bore 1-1. l he length of the nozzle extension I9 is such as to enter the central part of the brush bristles and it discharge enc1 2 l is spaced somewhat above the top end 22 of the brush holding member 1-2, so as to suitably distribute the soap among the bristles. The cap -l2 has a bent in portion 1211. against which the base of thebristles 31 may bepressed, and a-flaring outward portion 12b, the walls of the opening formed. by the flange or bent in portion l2a encompassing the bristles.

Thecombining member 15 preferably by the curved surface 23 presses upon the bottom harde ened portion or base 30 of the bristles 3|. As the brush (without the usual handle) is utilized, the bristles have a tendency to spread out laterally from their hardened base, and when these are gathered and compressed, so to say, and 'released, whilefheingguided throughthe end opening ;22 of the member 12, their expansive force presses against the rim .of the opening, and thus holds the "brush "in position so that often it is not necessary to press the hardened base entirely against the curved end portion [2a.

The lower open end of the body portion, In is closed by a thimble 25, which has exterior screwthreads 26 to engage the interior screwthreads H of the body member 10, and has a base portion 21 preferably radially disposed, with a hollow 28 to enablea thumb or finger to enter and press upon the walls for turning the thimble. Preferably, the interior surface is provided with lands 28a. The upper surface 29 of the thimble has a contour in conformity with the inner contour 29a of the combining member, so that every portion of the soap between these surfaces may be squeezed into the bore l1, when the thimble is at the end of its working run. The external screw threads 26 of-the thimble are identical in pitch with the external screw threads of the combining member l5.

With the brush in position and held by the combining member [5, with about one half of the body member I5 extending outside of the cap member, the body member I0 is screwed on to the projecting end of the combining member so as to take the position shown in Fig. 5. The interior of the body member has been filled with shaving cream or with a cylinder of moldable soap. The thimble is then screwed in to the body member to the extent of having the radial surfaces 21 in the transverse plane passing through the end of the body member as shown inFig. 1, and a slight turn of the thimble is sufficient to eject from the nozzle the necessary amount of soap or cream for the face lathering. The device is then ready for its next use, when again the only thing necessary is a slight rotative movement of the thimble.

When the thimble'25 reaches the position as shown in Fig. 3, a new supply of soap is necessary. The cap I2 with the brush and with the combining member I5, as an'entity, is then separated from the body portion Ill, by unscrewing.

The thimble 25 is then moved further along thev body portion Hi from its position asshown in Fig. 4, until the thimble 25 is entirely separated.

The interior of the combining member I5,- and its bore 20, as also the interior of the body portion I0 and the exterior of the thimble 25, may then be cleaned, and after the thimble has been re-inserted into the lower open end of the body portion ID, the interior of the body portion is again filled with a supply of soap or cream, and the body member is screwed on to the combining member.

The preferred dimensions, without limitation thereto, are: Length of body member 2 outer diameter of body member 1 /2"; length of brush holding cap 1; bore of nozzle 1%"; outer diameter of the upper endof nozzle 1%"; of the lower end 4''; length of screwthreaded part of combining member -7 height of thimble *4"; thickness of wall of thimble, body member and cap A diameter of bore of thimble hollow 1%"; all threads to be 16 per inch. Contents 2.495 cubic inches.

The parts are made of a suitable plastic material.

The brush cap l2 and the soap enclosing body member II! are designed to permit of easy separation so as to permit the loading of a semihard cylinder of soap which could not be accomplished should the soap chamber contain any mechanical units for the purpose of operating the brush. It is preferredto introduce the use of the soap cylinders due to their ready adaptability but the many forms of soap cream can be used.

The brush chamber I2 is also purposely designed With a view to using the present form of shaving brush knot into which will be introduced a hole of sufficient diameter to receive the spigot or nozzle 19. The brush upon being worn can be easily removed and a new one inserted without destroying any of the four parts of the complete assembly. a

The four parts have been designed with a view to having the whole assembly molded of some suitable plastic material without the necessity of introducing any metal parts into the completed product. However, the parts may be made of aluminium or other metal. It is also designed-so as to give a maximum of soap capacity without being a cumbersome unit to handle and this is accomplished by keeping the soap chamber free of all internally operated mechanical assemblies.

With the preferred dimensions described, the combined brush and soap holder has a capacity sufiicient to permit approximately 60 shaves without re-loading. By actual experiment, it was discovered that the inside of the soap chamber.

is left absolutely clean of any of the soap as the thimble assembly is worked forward, to the end of its run. I

The directing conception is the enclosing of a body of soap by a shell-like structure, in which the brush is held at one end and partitioned from the soap body, and into which brush charges of the soap body may be distributed, with the parts readily separable for cleaning and re-loading, and as readily assembled, all without projecting parts within or without the enclosure.

I have described an embodiment of my invention, but obviously various changes may be made in the details enclosed without departing from the spirit of the invention as set out in'the following claims.

I claim:

.1. In a combined shaving brush and holder, the combination of a shaving brush having one end of each bristle encased in .a hardened base having one end of each bristle encased in a hardened base having a fiat surface, abrush holding cap external screwthreads of said combining member unengaged by said internal screwthreads'to allow freedom of movement of said cap onsaid combining member, said combining member having a fiat surface abutting against said flat surface of said base and facing said inward flange and spaced from said inward flange to the extent of substantially theheight of the base of the brush, said combining member being capable of being screwed into said cap to secure the base of the brush between said flat surface of said combining member and said inward flange, whereby said inward flange of the cap is adapted to press against said base, and said base against said surface, to hold the brush from turning and to provide a seal against entrance of water, and on the separation of said combining member from said cap, a new brush may be substituted.

2. The structure of claim 1, in which said cap at its screwthreaded end has a cylindrical exterior, and,a terminal end, and said combining member having a bored central nozzle passing through said base, combined with a soap holder of cylindrical shape having its outer diameter equal to the outer diameter of said cylindrical exterior of said cap and having a terminal end abutting against said terminal end of said cap, and having interior screwthreads engaging the screwthreads of said combining member not engaged by said cap screwthreads, said screwthreads of said soap holder extending along the length of said soap holder, and means within the soap holder having exterior screwthreads engaging the interior screwthreads of said soap holder, which means are adapted to move inwardly of said soap holder'and press any soap in said soap holder into and through said bored nozzle,
