PORCELAIN HANDLE BRUSH.

Application filed April 26, 1926. Serial No. 104,850.

It is common to provide the porcelain handles of brushes, especially of shaving brushes with a metal ferrulewhich receives the brush head and is connected with the upperend of the handle by using cement, pitch or the like. This attachment of the brush head hitherto has been incapable of practical application, however because the connectionbetween the handle and the ferrule becomes loose and the brush head comes out.

The present invention relates to an 'improvement in the connection of a porcelain handle with the metal ferrule receiving the brush'head, whereby the usual attachment with pitch or cement is omitted.

For this purpose I insert between the peripheral walls of the porcelainhandle and of the metal cap a ring of elastic material, for example of cork, rubber, pasteboard or the like. The porcelain handle and also the metal ferrule are shaped in a conical manner, so that the elastic ring lying between the conical surfaces is pressed strongly and owing to the natural. adhesive capacity of the elastic ring the connection between the cap and the handle is assured.

The annexed drawing illustrates two examples of the invention without defining its limits and shows in a longitudinal section in Figs. 1 and 2 a shaving brush handle with the metal cap attached thereto.

According to Fig. 1 the porcelain handle is recessed and formed on its upper end with an annular shoulder Z) on which is provided an outwardly flaring Wall 0. This wall part 0 receives a metal ferrule (Z which is provided with a conically shaped peripheral wall e and serves for holding the brush head in known manner. Between the walls of these tapered parts 0 and a is inserted a cylindrical ring 7 of elastic material, for example of cork, rubber, pasteboard or any suitable material. By the pressure of the metal ferrule against the elastic ring owing to the natural friction capacity of the latter v Fig. 1.-

ferrule is further provided on its upthe connection between the handle and the ferrule. is assured. According to Fig. shows also the flar ng wall 6*,Wl11l6 the -metal ferrule is provided with a cylinring lying between the walls 0 and e bears on the one side against the conical outer Wall of the handle and on the other side against the cylindrical inner wall of the metal fere rule. By this attachment the same. effect in connecting the handle and the ferrule is obtained as according to the constructionof The per end with an inwardly projecting annular' rim 9, by whicha good closure in upward direction is assured.

What I claim is:

- 1. A shaving-brush comprising a recessed porcelain body having an annular under cut wall forming a shoulder above the said recess, bristles mounted in said recess, a metal ferrule encircling the bristles and resting on said shoulder, an elastic ring between the under out Wall of the body and said ferrule, said ferrule having an inwardly projecting annular rim overlying the under out Wall and engaging the bristles.

2. A shaving brush comprising a recessed porcelain body having an annular under cut wall forming a shoulder above the said recess, bristles mounted in said recess, a

metal ferrule encircling the bristles and resting on said shoulder, an elastic ring formed on its inner side conically and on its outer side cylin'drically between the under cut wall of the body and said ferrule, said ferrule having an inwardly projecting annular rim overlying the under cut wall and engaging the bristles. 1

In testimony whereof I aflix mysignature.

LUDWIG FULD.
