Christian E. A. Gronbech, of Woodhaven, New York. Shaving Brush.
1,409,168. Specification of Letters Patent. Patented Mar. 14, 1922.
Application filed November 11, 1919. Serial No. 337,123

To all whom it may concern:

Be it known that I, Christian E. A. Gronbech, a citizen of the United States, residing at Woodhaven, Long Island, New York, have invented certain new and useful Improvements in Shaving Brushes, of which the following is a specification.

My invention relates to improvements in shaving brushes of the type in which the handle constitutes the receptacle for shaving soap or paste, which may be forced into the brush by suitable means such as a plunger.

The principal object of the invention is to provide a simply constructed and efficiently operating device, which is sanitary in use, sightly in appearance and may be economically manufactured.

In the form of the invention illustrated, the handle serves to receive the shaving soap or paste and from which the paste may be forced into the head of the brush which is provided with a chamber or cavity for the reception of the paste.

In the accompanying drawing, wherein a preferred form of the invention is illustratively exemplified,

Fig. 1 is a substantially vertical sectional view of my improved fountain brush.

Fig. 2 is a transverse sectional view taken on the lines 2—2 of Fig. 1.

Fig. 3 is a bottom plan view of the base of the handle portion.

Fig. 4 is an elevational view illustrating the mode in which the handle may be filled with shaving soap or paste.

In Fig. 1 the handle 10b is provided with oppositely disposed longitudinal internal guide ribs 19a, and an integral bottom 12b having a depending internally threaded collar 12y to receive the threaded head 15b of the brush 16 having a chamber 18 through which the paste passes from the interior of the handle 10b to the bristles of the brush itself. Extending lengthwise of and rotatable within the handle 10b is a threaded shaft 23 passing through a composite plunger consisting of oppositely disposed discs 24 and an intermediate washer 25. The plunger is provided with diametrically opposite peripheral indentations 26 into which the guide ribs 19a extend to prevent rotation of the plunger in the handle. Resting on the upper end of the handle 10b is a knurled cap 27 to which one end of the shaft 23 is secured by a screw 28 the head of which rests in a countersunk portion of the cap. The opposite end of the shaft 23 rests on the top of the base 12b, and adjacent this end of the shaft the latter is provided with an axial bore 29 in alinement with the opening 17b in the head of the brush. Ducts 30 are formed in the bottom of the shaft 23 leading to the bore 29 to permit the passage of paste from the handle 10b through the ducts 30 and bore 29 into the chamber 18 in the brush head.

This form of the invention is especially adapted for refilling, and Fig. 4 shows the manner in which the handle 10b may be filled or refilled. The bottom 12b (Fig. 3) is provided with a filling opening 31 and an air escape vent 32, and in order to fill handle 12b a full tube 33 is connected by means of a union 34 to the filling opening 31 and the contents of 33 forced into 10b. As 10b fills with the paste, the displaced air will be forced out of the casing 10b through the vent opening 32.

The invention operates in the following manner:—The cap 27 and shaft 23 being rigidly interconnected turning of the cap will cause rotation of the plunger 24—25. The plunger is held against rotation by the ribs 19a and indentations 26, but as the shaft 23 is rotated in the proper direction the plunger will be caused to descend exerting pressure on the paste contained in the casing 10b and forcing a part of the paste through the ducts 30 the bore 29 and into the chamber 18 of the brush. When the handle 10b has been emptied of paste it may be refilled as illustrated in Fig. 4 in the manner above described and which need not be repeated.

What I claim is:—

1. In a fountain shaving brush employing soap paste, a hollow handle member having one end provided with a full bore opening and the other end provided with restricted openings, a spindle having communicating passages leading to and opening into one of said restricted openings in the end of said handle and the other of said restricted openings adapted to be used to refill said hollow handle, a brush attachable to the end of said handle having the restricted openings and an inlet in the head of said brush adapted to register with the restricted opening communicating with the passage in said spindle, said refill openings being closed by the head of said brush, and a plunger mounted on said spindle and adapted to traverse the length of the latter to eject the soap paste through the passage into the brush.

2. In a fountain shaving brush employing a soap paste, a hollow handle member having one end provided with a full bore opening and the other end provided with restricted openings, a screw spindle rotatably mounted in one of said restricted openings and provided with communicating passages leading from the interior of the handle to the restricted opening holding the spindle, a brush attachable to the end of said handle having the restricted openings and an inlet in the head of said brush adapted to register with the passage communicating with the interior of the handle, a non-rotating plunger reciprocable in said handle and provided with a threaded opening adapted to receive the threads of said screw spindle, and a cap fixed to the free end of said spindle and provided with a flange embracing the sides of said handle adjacent its open end, said cap capable of rotating said spindle to move the plunger axially of the interior of said handle.

3. A device of the character described, comprising a hollow handle member adapted to receive paste, said handle member having one end provided with a full bore opening and the other end provided with restricted openings, one of said openings being centrally located and the other openings arranged on opposite sides of said central opening, one of said last named openings being provided to permit soap paste to be injected into the interior of said hollow handle and the other of said last named openings being provided to permit the escape of air which is replaced by the incoming paste, a brush attachable to the end of said handle having the restricted openings and an inlet in the head of said brush adapted to register with the central restricted opening in said handle and the adjacent surface of said head adapted to close said refill openings, and a piston adapted to traverse the bore of said hollow handle member.

4. In a fountain shaving brush employing soap paste, a hollow handle member having an end closure provided with a plurality of restricted openings, one of the same being provided to permit soap paste to be injected into the interior of said hollow handle, and a second of the same being provided to permit the escape of air which is replaced by the incoming paste, a brush attachable to the end of said handle having the restricted openings, the head of said brush having an inlet adapted to register with one of the restricted openings in said end closure, and the adjacent surface of said head being adapted to close all of said openings except the one with which said brush inlet registers, and a piston adapted to traverse the bore of said handle member.

In testimony whereof I have affixed my signature in presence of two witnesses.

Christian E. A. Gronbech.
