Patented Jan. 7, 1936 UNITED STATES PATENT GFFICE DISPENSING FOUNTAIN BRUSH Weldon D.'Henderson, Hollywood, Calif. Application October 9, 1934, Serial No. 747,550

4 claims. (c1. 15-135) I 'Ihis invention relates to dispensing fountain brushes.

The general object of the invention is to provide a dispensing fountain brush which'is of novel construction.

A more specific object is to provide a fountain brush wherein the brush head can be removably mounted on a tube of shaving cream.

yA further object of the invention is to provide a novel brush head for use with a tube of shaving cream.

Another object of the invention is to provide a novel collapsible tube end structure which is particularly adapted for use with a fountain brush head.

Other objects and the advantages of my invention will be apparent from the following description taken in connection with the following drawing, wherein:

Fig. l is a side elevation of a dispensing fountain' brush embodying the features of my in vention;

Fig. 2 is a fragmentary longitudinal sectional view through the operating portions of the brush;

Fig. 3 is a fragmentary sectional view taken on line 3--3 of Fig. 2 and drawn to a larger scale;

Fig. 4 is a view similar to' Fig. 3 showing parts in another position; and,

Fig. 5 is a fragmentary view similar to Fig. 2 showing a position of the parts with the cream being extruded.

Referring to the drawing by reference characters, I have shown my invention as embodied in a fountain brush indicated generally at i0. As shown I employ a novel collapsible tube il which may be filled with a suitable shaving cream l2 and which has a shoulder I3 which terminates in a reduced neck I4. 'Ihis neck is provided with external threads I5 and with internal threads I8. Normally a closure cap may be applied to the external threads I5 or a plug may be applied to the internal threads.

The member lli includes a head i3 in which bristles of any desired length are suitably secured in the usual manner. Ihe head i8 is preferably made of hard rubber or bakelite. Mounted within the head I3 I show an outer valve member 20 which is preferably made of die cast metal and includes a cylindrical rear portion 2i and a frusto-conical forward portion 22. This outer member 28 is preferably cast in the head `I3 and portions 23 of the head material fit pockets 24 in the member 28 to hold the parts I3 and 2l rigidly assembled.

The cylindrical portion 2| is provided with internal threads 25 which engage the external threads l5 on the tube neck il. 'I'he outer valve member 2li is provided with an end wall 2i which has an aperture 21 therein. One portion of this aperture 21 is arcuate and the other portion is a 5 chord `uniting to the ends of the arcuate portion (see Figs. 3 and 4).

Within the exterior member 20 I show an inner metal cylinder 28 which is rotatably mounted `within the member 2li and is secured in position by a headed fastening member 28 the head of which engages the `outer face of the end wall 26 of the outer member. The cylinder 28 is provided with a threaded rear portion 30 on its exterior surface which ilts the interior thread i6 on the tube neck i4.

In the end wall 26 of the member 28 I provide an inwardly extending pin 3| which is positioned in an arcuate slot 32 in the end of the member 28. When the member 28 is rotated relative to the member the pin 3| restricts the rotation of the member 28 to 180 degrees of travel.

'I'he member 28 has a longitudinal bore 33 therein which at the rear end is circular. One wall 34 of the bore 33 convergently tapers forward towards the opposite side and at the forward end terminates in an opening 3l which is 'of the same shape as the aperture 21 in the end wall 26 of the member 2li.

In operation when the opening 35 of the member 28 registers with the aperture 21 of the member 20 as shown in Figs. 2, 3 and 5 and pressure is applied to the tube li the contents l2 thereof is forced out of the tube neck I4 into the bore 33 of the member 28, through the bore 33 and out through the aperture 21 in the member 28 into the brush bristles I8, as shown in Fig. 5.

After sufficient amount of the material I2 has been discharged into the bristles the operator holds the brush portion lli and rotates the tube il to the right. As the tube Il is thus rotated the member 28' is moved with it until the pin 3| prevents further movement thereof. In this position the opening 35 of the member 28 is out of register with the aperture 21 in the member 2l as shown in Fig. 4 and thus passage through the opening 35 is restricted by the end wall 28 of the member 20.

In the use of my invention the brush element with the contained valve may be distributed free by the seller of the shaving cream or there may be a small charge made for this brush. Thereafter, the purchaser will usethe cream until the tube is exhausted after which he will purchase another ,tulaerto` il the brush head. Since, my improved tube having the internal and external vthreads on the'neck is necessary to cooperate with the brush head the owner of a brush head will be compelled to buy the particular shaving cream which is contained in my improved tube so thus sales will be increased and the user will be assured of a consistently satisfactory product.

From the foregoing description it will be apparent that I have invented a novel fountain brush which can be economically manufactured and which is highly eiiicient in use.

Having thus described my invention, I claim:

1. The combination of a collapsible tube and a shaving brush, said collapsible tube including a neck having external and internal threads thereon, said brush including a bristle portion and a head, said head having an external valve member rigidly secured therein, said external valve member having interior threads thereon tting the outer threads on said'neck, and a rotatable cylindrical valvevelement within said valve member, said valve element having external threads thereon tting within said neck.

2. The combination of a collapsible tube and a shaving brush, said collapsible tube including a reduced discharge neck having external and internal threads thereon, said brush including a head having a bristle portion thereon, said head having a valve member therein, one end of said valve member extending into said bristles and having a. discharge opening in the end thereof positioned at one side of the :longitudinal center thereof, the opposite end of said valve member including a threaded portion engaging said external threads of said tube neck, a valve element rotatably mounted in said valve member and means to secure said valve element to said valve member to limit relative longitudinal movement, one end of said valve element including a threaded portion engaging said internal threads of said tube neck, said valve element having a longitudinal conduit therein, one end of said conduit communicating with the interior of said tube neck and said conduit converging towards the opposite end to form a discharge opening positioned at one side of the longitudinal center of the valve element.
