FOUNTAIN-BRUSH.

Specification of Letters Patent.

Patented J an. 15, 1918.

Application filed February 27, 1917. Serial No. 151,264.

To all whom it may concern:

Be it known that I, CONRAD J. BUSCH, a citizen of the United States, residing at WVyomissing, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Fountam-Brushes, of which the following is a specification.

The present invention relates to improvements in fountain brushes of that type embodying means for feeding a substance suitably contained in the body of the brush to the bristle portion thereof. 7

In carrying out my idea the invention is illustrated herein as adapted for shaving brushes but it will be clear that the scope of the invention is not restricted to such embodiment.

An important phase of these devices lies in their construction by means of which the assembling of the parts is readily accomplished and the renewal or replacement of such parts effected with ease. It is, there fore, comprehended by my invention to provide ejector means for the brush assembled in a unit and including a plunger or piston operable in a feeding tube with which it has interlocking connection enabling the feeding means to be connected with or mounted upon the brush body or displaced therefrom by manipulation of said plunger element.

WVith the above and other objects in view, this invention consists in the novel construction, combination and arrangement of parts, as hereinafter more particularly pointed out and illustrated in the accomwherein: V

Figure 1 1s a longitudinal sectional view of a. brush constructed in-accordance with my invention. a r r Fig. 2 is a side elevation of the ejector means for said brush. 7 7

Figs. 3 and 41 are sectional views on the lines 3-3 and H respectively of Fig. 1.

Throughout the following detail description, and on the several figures of the drawing, similar parts are referred to by like reference characters.

Referring to the drawing 1 designates the bodyor handle portion of the brush'connewbi s-matt r of h invention, said body portion being provided with a chamber 2 to receive the substance which is designed to be fed to the bristle portion 3 of the device. The bristle portion ismounted in a head 4 which has threaded connection with the lower extremity of the handle as indicated'at 5 and a threaded aperture 6 extends through the lower portion of the handle so as to receive the ejector means hereinafter more particularly set forth. 'At the opposite end the handle is provided with a threaded filler cap ing a central opening through which the feeding means aforesaid extends.

The feeding means above referred to, as clearly shown in Fig. 2 constitutes a unit capable of being attached to the body of the brush for supplying the substance in the chamber 2 to the bristle portion 35 as hereinbefore premised. This unit consists of a feeding tube 8 having an exterior threaded portion 9 adapted to be screwed into the threaded opening 6 in the brush body. The tube 8 extends longitudinally of the handle and through the chamber 2, being formed preferably with a beveled seat 10 for the cap 7. Operable within the tube is a plunger 11, the upper end of which (BX-1 tends through the cap 7 and is provided with a knurled head 12 by which the operator is able to reciprocate the plunger forthe purpose of effecting feed of the substance from the chamber 2. a

The tube 8 just above the threaded portion is provided with a feed opening or openings preferably the latter, 13, and above these openings the tube 8 is oppositely slotted as at 14, said slots communicating with the feed openings 13 just described. Extending transversely of the plunger and mounted therein so as to project through the feed openings 13 is a guide member or pin 15 and a spring 16 preferably embraces the tube seating upon the said pin at one end and against the opposite extremity of the tube as clearly shown in Fig. 2. The plunger through the instrumentality of the spring is maintained in its innermost position effectively closing the feed tube 8 against discharge ofits contents. Upon ret t owf e Plu r 11! oe ypf th 7 havbody, the lower extremity thereof is brought into a position above the threaded portion 9 of the tube and uncovers portions of the openings 13 through which the contents of the chamber 2 pass into the tube 8. Upon movement of the plunger inwardly of the tube said contents which have entered the tube are ejected into the bristle portion 3,

v latter will not become clogged and will more I ing a hollow effectively pass into the feed tube. It is to be understood that in this particular device the chamber is to contain soap either in liquid, powder, or paste form.

The pin 15 by reason of its operation in the feed openings 13 and the slots 14 readily permits reciprocatory movement of the plunger but rotation of the plunger will obviously effect rotation of the tube by virtue of the interlocking connection afforded by this pin in the slotted walls of said tube.- Thus the ejecting means may readily be connected to the body of the brush or disconnected therefrom by suitably rotating the head 12 of the plunger; This is an important feature of this" device.

When it is desired to fillthe chamber 2,

the cap 7 is unscrewed and by slightly retracting the plunger 11, the soap may be introduced into the chamber 2, it being understood that the plunger is not withdrawn in this filling operation sufficiently to uncover the feed openings It will be apparent from the foregoing description that the bristle or brush portion 3 maybe renewed as occasion may require by reason, of its detachable connection with the handle 1 and the body portion may be sterilized whenever necessary or the ejecting means may be easily removed for replacing of parts or cleansing owing to the facility of the removal of the parts as above described.

Having thus described my invention, what I claim as new is: r

1. A brush of the class described comprismg a hollow body constituting a supply chamber and means for ejecting the contents of said chamber including a feeding tube having means for connecting the same to the body and into which the said contents are received from the chamber, and a plunger operable in said tube and having operative connection with the latter whereby, on rotation of the plunger, to connect the tube to the body.

2. A brush of the class described comprisbody constituting a supply chamber and means for ejecting the contents of said chamber including a feeding tube having means for connecting the same to the body and into which the said contents are received from the chamber, a plunger including a manipulating handle operable in said tube, and. pin and slot connection between the plunger and tube for connecting the tube to the body upon rotation of the handle.

8-. A brush of the class described comprising a body having a supply chamber and a bristle portion, feeding means for feeding the contents of the chamber to the bristle portion comprising a tube arranged to receive the contents of the supply chamber thereinto and having a threaded portion for connection with the body, able in said tube, the plunger with the tube for rotation therewith to effect the connection aforesaid while permitting free reciprocal movement of the plunger. 7 V

4. A brush of the class described comprising'a body having a soap chamberand a bristle portion, feeding means for feeding the contents of the chamber to the bristle portion comprising a tubeextending longitudinally through the chamber aforesaid and having an opening communicating therewith, a plunger in said tube, and projections on the plunger extending through the feed opening aforesaid into the chamber and constituting agitating means for the contents of the chamber, said projections connecting the tube for rotation with the plunger but permitting free reciprocatory movement of the latter. 7

5. A brush of the class described comprising a body having a soap chamber and a bristle portion, feeding means for feeding the contents of the chamber to the bristle portion comprising through the chamber a slot therein arranged within the chamber aforesaid,'a plunger operable in the tube and extending outwardly of the body portion, and projections extending through the a feeding tube extending aforesaid, and having a plunger operand vmeans interlocking slot in the tube and constituting an inter- 7 locking connection between the plunger and tube whereby the latter may be rotated by the plunger. j V

6. In a shaving brush, the combination with a hollow handle and a bristle portion, ofej'ecting means comprising a feed tube extending from the handle into the bristle portion and having a threaded portion for connection with the handle, said tube having a lateral feed opening, a plunger operable in said tube, a pin projecting laterally from the plunger and through the feed opening aforesaid, a spring embracing the tube and seated against said pin for efiect-,

ing movement of the plunger in reciprocation thereof, and a "closure cap for the handle through which the plunger extends and having connection with the feed tube aforesaid.

7. Ejecting means for fountain brushes comprising a feed tube having lateral feed openings at opposite sides, a plunger operable in said tube and normally closing the feed openings aforesaid, a pin mounted in the plunger and extending laterally throu h the feed openings aforesaid for establis 10 mg interlocking connection between the plunger and the tube, and a spring seated upon said pin for holding the plunger in position normally closing the feed openings.

In testimony whereof I aflix my signature. 15
