E. J. CHARLES SHAVING BRUSH Filed Jan. 25, 1955 mmmtoz J17? GarZea abhor/M 043 o.

Patented Jan. 9, 1934 UNITED STATES r Ara NT err! CE The invention relates to shaving brushes of the general type in which a container for shaving cream or the like (hereinafter referred to as shaving cream) is provided within the brush handle, and in which provision is made for discharging the shaving cream from the container into the bristle portion of the brush.

It is the object of the invention to provide an exceptionally simple and inexpensive brush of the character set forth, yet one which will be efficient, may be quickly and easily filled, may be kept clean and sanitary, may be easily operated to discharge any desired quantity of shaving cream, and will be generally desirable.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawing.

Fig. 1 is a vertical sectional view through a brush constructed in accordance with the invention.

Figs. 2 and 3 are detail perspective views or" parts hereinafter described.

A preferred construction has been shown and will be specifically described, with the understanding however, that within the scope of the invention as. claimed, minor variations may be made.

The numeral 10 on the drawing, denotes a bristle-carrying cup and 11 refers to the bristles carried thereby, said bristles being anchored in any appropriate way in the cup bottom 12, for instance by forming this bottom from rubber and 35 molding the bristle ends therein. This bottom 12 is formed with a central opening 13 through which a shaving cream discharge neck 14 extends, said neck being rigidly carried by a fixed disk 15 which is disposed within the cup 10 and pref 40 erably rests upon said bottom 12. The rim of disk 15 is provided with a continuous beveled face 16 which is presented toward the open end of the cup 10, and if the disk be formed from metal, the beveled rim may be provided by stamp 5' ing said disk into the shape shown. The neck 14' is snugly received in the upper end of a tube 17 of rubber or the like, said tube having a discharge slit 18 in its lower end and being preferably flat to normally seal itself against discharge of shaving cream. When the cream is discharged with force through the neck 14 however, the tube 17 expands, thereby opening the slit 13 and allowing the cream to discharge into the bristle portion of the brush.

A handle 19 is detachably threaded at 20 into the cup 10 and is provided with a continuous beveled inner end 21 fluid-tightly abutting the bevel 16 of the disk 15. This handle is formed with a central cylindrical bore 22 opening through both its inner and outer ends, and a cylindrical tube 23 is tightly fitted into said bore, against the .wall of the latter. A tubular shaving cream cylinder 24 is snugly, yet rotatably fitted within the tube 23 and is held against withdrawal from the latter by means of a rib 25 which abuts the inner end of said tube. The outer end of the cylinder 24 is secured to and closed by a cap 26 provided with a downturned rim flange 27 which surrounds the reduced outer end 28 of the handle 19, said flange 27 being corrugated or otherwise roughened at 29 so that it may bereadily turned with the thumb and fingers, for a purpose to appear. The cup 10 is also preferably corrugated or otherwise roughened as indicated at 30, so that it may be readily held in one hand while the handle 19 is being turned with the other hand, when it is necessary to remove said handle for refillingthe cylinder 24.

The tube 23 forms a lining for the wall of the bore and is provided with helical slots 31, which provide the lined bore wall with helical grooves. The cylinder 24 is formed with two straight longitudinal slots 32. A cream-ejecting piston 33 is disposed in cylinder 24 and is provided with studs 34 which pass through the slots 32 into the helical grooves or slots 31, said studs being preferably formed by the ends of a pin 35 passed diametrically through an opening in the piston 33. When the cylinder 24 is rotated by means of the cap 26, it similarly rotates the piston 33, with the result that the studs 34 are caused to move upwardly or downwardly by means of the helical grooves or slots 31, according to the direction in which said cap is turned. The movement of the studs 34, effected by the grooves or slots 31, causes corresponding movement of the piston 33. It will thus be seen that by simplyrotating the cap 26, the piston may be operated to eject a desired quantity of the shaving cream 36 through the neck 14 and flexible tube 17, into the bristle: portion of the brush, so that it is only necessary to wet the latter in order to provide for the production of shaving lather. Turning the cap 26 in the other direction, will of course retract the piston 33 preparatory to refilling the cylinder 24. When such refilling is to be accomplished, it is only necessary to unthread the handle 19 from the cup 10, retract the piston 33 and refill. Upon unthreading of the handle, its beveled end 21 leaves the beveled face 16 of the disk 15, and cylinder 24 leaves said disk, the

parts

24, 23, 26 and 33 remaining unitarily connected with the handle 19, while disk 15 and parts connected therewith, remain unitarily assembled with the cup 10. After refilling, the handle is rethreaded into the cup and tightened, and the brush is then in condition for further use.

It will be seen from the foregoing that a device has been provided which is simple and inexpensive, convenient, easy to operate, and may be readily kept clean and sanitary, there being no danger of leakage. If, after using the brush, the cap 26 be retrogradely turned to some extent, piston 33 will be retracted, thereby creating such suction as to cause the tube 17 to tightly collapse and remain in this collapsed and sealed state. Then, when the brush is washed, all unused lather within its bristle portion, may be readily washed out, andthere is no danger of any more cream entering said bristle portion until the cap 26 is operated, The bristles may therefore properly dry, with no danger of even the innermost thereof, remaining damp, with danger of deterioration. Preferably, the construction is such that cap 26 must be turned clockwise to eject paste, and counter-clockwise to retract the piston.

I claim:

1. A shaving brush comprising a bristle-carrying cup having a shaving cream discharge opening in its bottom, a handle, means for detachably connecting said handle and said cup and for holding them against relative rotation except when detaching one from the other, said handle having a central cylindrical bore which opens through both of its ends, the wall of said bore having helical grooves, a tubular shaving cream cylinder rotatably fitted in said bore, said cylinder being open at its lower end, being closed at its upper end and having longitudinal slots, a cream extruding piston in said cylinder having studs passing through said longitudinal slots into said helical grooves, and means on the upper end of said cylinder whereby the latter may be rotated with respect to said cup and handle to effect movement of said piston.

2. A shaving cream extruding assembly for reception in a tubular shaving brush handle, comprising a, cylindrical tube to tightly and nonrotatably fit within the brush handle, said tube being open at both ends and having helical slots, a tubular cylinder fitted rotatably within said tube and having longitudinal slots, a cap secured rigidly and fluid-tightly to the upper end of said cylinder, said cap projecting radially beyond said cylinder and abutting the upper end of said tube, the lower end of said cylinder being provided with a peripheral rib abutting the lower end of said tube, and a 'piston in said cylinder having studs passing through said longitudinal slots into said helical slots.

3. A shaving brush comprising a bristle-carrying cup having an opening in its bottom, a fixed disk within said cup having a rim provided with a continuous beveled face presented toward the open side of the cup, said disk having a shaving cream discharge neck extending through the aforesaid opening, a handle whose lower end is threaded detachably into said cup and held against rotation with respect thereto except when detaching said handle from said cup, the lower end of said handle having a bevel fluid-tightly abutting said beveled face of said disk and separable therefrom as the handle is detached from the cup, said handle having a central cylindrical bore opening through both of its ends, the wall of said bore having helical grooves, a tubular shaving cream cylinder rotatably fitted in said bore, said cylinder being open at its lower end, being closed at its upper end and having longitudinal slots, a cream extruding piston in said cylinder having studs passing through said longitudinal slots into said helical grooves, and means on the upper end of said cylinder whereby the latter may be rotated with respect to said handle and cup to effect movement of said piston.
