UNITED STATES HENRY FREDERICK EBERT, OF NEW YORK, N. Y.

SHAVING BRUSH.

Application filed August 16, 1922. Serial m. seams.

To all whom it may concern:

Be it known that I, HENRY FREDERICK EBERT, a citizen of the United States, and resident of the borough of Queens, county 6 of Queens, city and State of New York,

have invented certain new and useful Improvements in Shaving Brushes, of which the following is the specification.

The handles of shaving brushes are usualin ly made of celluloid, bone, hard rubber or wood or combinations of these substances and it is well known that when the brush is placed in hot water to sterilize it, as is the custom with most users, the material it from which the handle is formed swells or becomes distorted to such an extent that the hairs of the brush become loosened either individually or in their entirety.

Means have been provided whereby the knot or innermost ends of the hairs are so secured that they will not readily loosen individually even upon the application of heat. but heat or hot water swelling the brush handle will allow the entire knot to become loosened.

It is to overcome this loosening of the hairs as'a whole, that I have devised and invented the construction which I am about to describe, the principal object of which 80 is to allow the brush to be introduced into and removed from the handle as a unit and to provide means for preventing the distortion of the handle, because of the application of heat and to provide means whereby a new brush may be inserted into the handle at any time, thus making it possible and practical to make brush handles more carefully than they have in the past been made and as ornate and artistic as the user may desire.

Other objects and the details of construction will be set forth as the specification progresses and the accompanying drawing should be referred to for a complete understanding of the specification which follows.

In the drawing Fig. 1, is a side elevation of my device.

gig. 2, a partial, sectional view thereof, an

Fig. 3, a sectional view, through the handle portion and a modification.

Slmilar reference numerals indicate like parts in all the figures where they appear The handle part may be of any desired shape or size and while I have in the drawing shown a shaving brush constructed according to my invention, it will be understood that brushes for other purposes may be similarly made.

The handle that I have shown may be made in two parts, that is, a grip part 5 and an enlarged portion 6, into which the brush is to be secured.

As, in many brushes, these two parts may be of different material, the grip portion 5 being of horn and the enlarged member 6 being of hard rubber or any other suitable or desirable combination may be made.

These two parts are secured by screwthreading or otherwise, but as this is com men and well understood I will not describe it.

At. one end of the member 6, I produce a bead 7, the bead surrounding the open portion of the member 6 into which the brush is to be introduced.

In the open end of the member 6 I introduce a screw-threaded cylinder or thimble 8 and the outer end of this thimble is spun over the bead 7 as shown at 9. As this member 8 is continuous, the bead 9 will be completely annular and will serve effectively to retain the open end of the member 6 against distortion.

Into the screw-threaded member 8, I introduce a second screw-threaded thimble or cylinder member 10 upon which is secured a knurled operating ring 11 and into this cylinder 10, I introduce the knot 12 of the brush 13 securing the knot by means of suitable cement as indicated at 14 and upon the cement and within the end of the cylindrical member 10, I may place a metallic disc 15.

The brush 13 may be formed of hair or bristles as requirements may dictate and its shape will also be controlled by the requirements of the service in which it is to be put.

When assembled as shown, it will be fully appreciated that the brush and the cylindrical member 10 may be withdrawn from the handle as and when desired and a new brush substituted if such shall ever be required.

In Fig. 3, a cylindrical member 16 is shown having a slot 17 and the cylindrical member 18 which receives the brush is not screw-threaded, but is provided with pins 19, which operate in the slot 17 in the manner well known in bayonet joints and while nee other means for securing the parts may be employed, I prefer the whole as first above I set. forth.

Having carefully and fully described my invention, what I claim and desire to obtain:-

A brush head and a non metallic handle therefor, said handle being provided with a. brush head receiving recess, a cylindrical metallic member withm said recess, one end portion of said cylindrical member being spun over the end of the handle adjacent said recess, a cylindrical, metallic member within which the brush head is secured and means upon both said cylindrical members for securing them in operative relation.

Signed at the borough of Brooklyn, county of Kings, city and State of New York, this 14th day of August, 1922.

HENRY FREDERICK EBERT.
