SHAVING-BRUSH.

Specification of Letters Patent.

Patented Nov. 8, 1921.

Application ied February 21, 1920. Serial No. 360,511.

T 0 all whom t may concern:

Be it known that I, RAYMOND F. Tin'rfrs, a ycitizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented. a new and useful Improvement in Shaving-Brushes, of which the .following is a specification.

This invention relates to self-feeding shaving brushes and, while it has more particulai` reference to the provision of a shaving brush for containing and feeding shaving powder, it will be apparent that certain of its features may be usable in the feeding of other shaving materials.

A principal object of my invention is the provision of a shaving brush which may contain shaving soap in powdered form and insure the accurate feed of desired and appropriate amounts of it. The feeding of soap of this character in a self-feeding shaving brush presents peculiar difiiculties because of the fact that the soap when in powdered or granular form does not readily fall into feeding devices of the usual character. My invention contemplates, among other features, the provision of positive means for abstract-ing the charges to be delivered to the bristles.

Another diiculty in the use of shaving powders in self-feeding brushes has resulted from the increasing of the tendency of the material to cake or compact itself into a solid mass upon the admission of any moisture into the powder reservoir and my invention contemplates as a further important feature the provision of a delivering device which will be moisture excluding.

The invention has for a further important object the provision of a shaving brush of the character described of simple, cheap construction, capable of easy operation, and consisting of parts so constructed and arranged as to prevent the necessity of frequent repair or replacement.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which taken in connection with the accompanying drawings discloses a preferred embodiment thereof.

Referring to the drawings,-

Figure 1 is a side elevation of a shaving brush embodying my present invention;

.Fig 2 is a central, longitudinal sectional view thereof;

Fig. 3 is a view similar to Fig. 2 with the l parts arranged in diiferent positions;

Fig. 4 is a section taken substantially on the line 4-4 of Fig. 3;

Fig. 5 is a section taken on the line 5--5 of Fig. 3;

Fig. 6 is a section taken substantially on the line 6-6 of Fig. 3; and

Fig. 7 is a perspective view of the feeding sleeve.

For the purpose of illustrating my invention I have shown on the drawing a shaving brush having the usual tuft of bristles 11 secured in a handle 12, which handle provides a reservoir for the holding of shavihg powder. The handle consists of a tubular body 13 of metal or other suitable material fast at its lower end in suitable fashion in the brush head 14. This brush head is provided with a central opening 15 in which the tuft of bristles 11 is secured. The tubular reservoir body is provided with a tapered orconical lower end 16 through which a tube 17 extends. This tube is fastened in the conical end and extends through the base 18 of the tuft providing thereby a portion extending out a substantial distance from the lower or feed end of the reservoir. J ust above the feed end of this reservoir the tube is provided with perfor-ations 19 in its side, which as will be presently described permit the soap material 21 to pass through into the inside of the tube where it may drop down into the bristles or be pushed down by a plunger provided for the purpose.

This plunger consists of a rubber body 22 fitting snugly within the tube and mounted upon the threaded end 23 of the plunger rod 24; The top of the body 13 of the reservoir is closed by a removable cap 25, having a central opening 26 through it. The plunger rod 24 extends through this opening and is provided at its outer end with a hand piece or buttonV 27 to facilitate manipulation.

I provide means in the embodiment of my invention shown on the drawing both for insuring that at each manipulation of the plunger soap powder will enter through the perforations in the tube and also insuring that the charges entering will be the predetermined amount desired. This .means consists of a sleeve 28 having a sliding lit about the tube. Near its bottom the material of the sleeve is cut and bent out in thev form of fins 29 which scrape the Vpowder from the body andcause it to slide down the fins and through the perforatlons, At

the topl the sleeve extends above the end of the tube and is provided with a cap 31 having a central perforation through which the plunger rod 24 extends. 33 are fixed upon the plunger rod, one of these collars 32 being provided between the cap 31 of the sleeve and the cap 25 of the reservoiigand the other 33 being located within the tube and at the upper end of the plunger. l'

In service the action of the brush is as follows: Fig. 2 shows the arrangement` of the parts in normal relation and this is the relation they-assume after each use ofthe brush. Tosupply soap to the brush the finger piece or button 27 is lifted moving the plunger upwardly so that it uncovers the ports or apertures in the tube. As it nears the top'of its stroke thecollar 33 is brought into lengagement with the cap 31 and further` lifting movement, which is slight, causes elevation of the sleeve to the position shown in F ig. 3.V -In this movement the fins scrape off and Vcause the desired. minute amount of powder to enter within the tube and immediately thereafter the sleeve closes the ports 19. Downward movement ofthe shown in Fig. 2, ejecting all plunger is next. accomplished by returning the button 27 to its normal position, pushing the plunger down and back to the position of the powder into the bristles. As the plunger nears the bottom of Vits stroke the collar 32 .on the plunger rod engages the outer surface of theV cap 31 and pushes the sleeve back to normal position, The upward movement of the plunger is of course limited by engagement of the collar 32 with the inner face of the cap 25. In order that the sleeve and tube may be maintained in relation to produce the desired relation between ports or aperturesl) and the tins 29 of the sleeve, I provide deformations 34 and-35 in the tube and sleeve respectively as may be seen in viewing F ig. 4. The deformation 34 in the tube extends merely a limited distance, i

being confined tothe within the reservoir. l

The 4rubber plunger fits with sufficient tightness in the tube to prevent leakage of moisture back into the powder and should portion of the tube the brush be wet before the plunger is manipulated and the soap ,applied to the bristles return of the plunger to normal position in .the soap delivering action wipes the inside of the tube dry, much after the manner of a window squeegee; The action of the parts in delivering the powder is such Two. collars 32 and that danger of water being admitted to the reservoir through the brush is negligible.

I prefer to -inclose the handle forming the reservoir within a covering sheet of leather 36 and to provide a similar sheet of leather 37 for the cap.

It is thought that the invention and many ofoit-s attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
