Application led January 22, 1920, Serial No. 353,132. Renewed .Tune 21, 1922. Serial No. 569,880.
and State of Tennessee, has invented certain new and useful Improvements in Shavlng Brushes, of which the following is a specification.
This invention relates to improvements in shaving brushes.
The prime object of the invention is to provide a brush with a reservoir for receiving plastic soap, and means for ejecting same into the bristles, and so arranging the parts as to form a vacuum in the reser voir to withdraw surplus soap after use of the brush, to prevent waste.
A further object of the invention is to provide a brush mounting to permit of the convenient assemblage or separation of the parts to maintain the brush in a sanitary condition. f
A still further object of the invention is to provide a brush structure having a plastic soap reservoir, and a powder container which 1s absolutely water-proof.
Another object of the invention is the provision of duct or tubular means for expressing the soap to the bristles, and arranging the brush head and associated parts to form a frictional grip between the handle, brush head and tubular means for convenience in holding the elements together.
The invention also comprehends improvements in the details of construction and arrangement of parts which will be hereinafter described and particularly pointed out in the claims.
In the accompanying drawing:
Fig. 1 is a sida elevation of my improved brush.
Fig. 2 is a vertical, central section of the same.
Fig. 3 is a detailed prospective View of the combined powder container and soap plunger. j
Fig. 4 is a detailed View of the brush head.
The numeral 1 indicates a cylindrical reservoir which is internally kthreaded as at 3. Engaging the threads 3 at the lower end of the reservoir is an inverted bottom cup member 4, provided with a shoulder 5, against which the lower edge of the cylindrical reservoir seats. The cup member 4 is hollow on its under side, as shown at 6,
vtom edge of the cup member.
and is further provided with a central tube 7, which extends below the piane of the bot- The top of the cup member is flat, and forms the bottom wall of the reservoir, and the opening through the tube communicates with the said reservoir to provide a passage for the plastic soap.
Fitting within the hollow portion 6 of thc cup member, is a brush head 8, formed with a central opening 9, and hollow on its under side, as shown at 10'. Depending centrally in the hollow portion 10, is an outwardly tapering projection 11, through which the opening 9 extends, and the inner side wall of the hollow portion of the head is corrugated as at 12. The bristles forming the brush are forced into the hollow portion 10, and are confined between the tapered wall 11, and the corrugated wall 12 which serves to maintain said bristles in the fixed position in the head. By this construction a cavity 13, is formed in the center of the bristles to receive a rubber or other flexible tubular member 14, frictionally supported on the tube 7. The opening 9, in the brush head is of suiiicient diameter to permit the tubular rubber member 14, topass therethrough when the parts are assembled, as clearly shown iu Fig. 2.
The brush head frictionally engages the wall 6 of the bottom cup member, while the wall of the opening 9, frictionally'engages the rubber tubular member 111. This frictional engagement between the head and the cup member forms a means for holding the brush in fixed relation, and is one which permits ready and convenient assemblage or removal of the parts. Engaging the threads 3, of the cylindrical yreservoir 1, is a hollow plunger 16, formed at its lower end with a threaded portion 17, and provided at its upper end with threads 18, below which is an annular fiange 19. Snugly fitting over the cylindrical reservoir 1 is a sleeve 20, Vthe upper end of which engages with the flange 19, and in the sleeve, below the flange are vent openings 21, to permit the exit of air as the plunger is adjusted in or out in the reservoir, when using the brush. This sleeve constitutes an enclosing or finishing member between the cylindrical reservoir 1, and the hollow plunger, while the openings 21 prevent the accumulation ot K interiorly screw-threaded, as at 23, and engaging the same is a cup shaped cover 24, provided with an opening 25. Fitting over the cover, and engaging the threads 18, on the plunger is a cap 26.
Assuming the parts are in the position shown in Fig. 2 and plastic soap is in the reservoir between the bottom of the plunger 16, and the bottom cup member 4, and powder is in the hollow portion of the plunger 16,- by turning the cap 26, it engages the flange 19, and forces the sleeve down on the outer surface of the plunger and expels the air from between the parts through the openings 21, and also forces the plunger down on the soap and expels the same through the tubes 7 and 14 and into the center of the` bristles. Obviously, when the bristles are moistened, the plastic soap is converted into lather, the rubber tube readily yielding when the brush is used.
After the brush has been used, the plunger is rotated slightlyvin the opposite direction, which creates a partial vacuum in the reservoir, the excess plastic soap in the tubes being thereby withdrawn into the reservoir, so that when the bristles are subsequently washed, there is no chance-of the soap remaining in the bristles, thus avoiding the possibility of an uns'anitary condition aris-` ing with the bristles.
The construction described has been designed to produce a` practical, convenient and sanitaryy shaving brush.y It folglgows' from the foregoing description that the expulsion of the plasticsoap into the bristles will be such that thel soap vwill be sustained within the bristles until worked up into lather, and that liability of the soap` being retained in the bristles after the plunger is withdrawn is practically impossible. The hollow plunger contains' powder, and after shaving the cap is removed from the handle and the brush is inverted and the powder` is sifted through theopening 25. The arrangement of the cover 24, prevents undue waste of the powder, and when the cap is applied it serves as a cover for the opening as well as a Iconvenient knot for rotating the plunger.
What I claim is:
1. A shaving brush comprising a handle, an inverted cup arranged in the lower end of the handle a-nd having a central tube projection openingA thru the cup, a flexible tube fitting over the tube projection and extending below the same, a brush head having a Wall fitted within the inverted cup and an annular projection within said wall adapted to overlie the fieXible -tube to bind said flexible tube between said wall and the wall projection of the cup, the space between the wall and annular projection of the brush head being formed to receive the brush bristles.
2. A shaving brush comprising a handle formed at its lower end with an inverted cup from which depends a tube, a rubber tube forced o-n the first mentioned tube, a hollow brush head having a central projection formed with an opening, the rubber tube frictionally engaging the wall of the opening and the side of the brush head frictionally engaging the wall of the inverted cup on the handle to lock the head and handle together, and a plunger in the handle to force soap through the tubes to the bristles.
3. A shaving brush comprising a hollow internallythreadedy handle, an inverted cup having a reduced portion externally threaded and engaging the internally threaded portion of the handle, the inverted cup having l a central reduced tubular extension, a ilexible tube frictionall'y held on the tubularextension and depending below the latter, a brush head having a central projection, the brush head frictionally engaging the walls of the inverted cup and the central projection frictionally engaging the flexible tube and binding the same on the .tubular extension of thecup, whereby to hold the brush head on .the handle, anda plunger for forcing soap thru the tube to the bristles of the brush.
In testimony whereof I aflix my si ature.
