BRUSH.

Specification of Letters Patent.

Patented Oct. 25, 1910.

Application filed January 15, 1910. Serial No. 538,176.

To all whom it may concern:

Be it known that I, Jnssr. L. HITZ, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Brushes, of which the followingis a specification.

This invention relates to brushes, and.

more I particularly to that class of brushes wherein the brush is provided with a magazine or reservoir for containing a supply of the material to be used with the brush.

- The object of this invention is to provide an improved form of construction for brushes of this type; to provide means -whereby the brush proper and the conduit and valve thereof may be readily cleaned.

Another object is'to provide a brush, having a fixed handle, with a reservoir or magaprovements, Fig. 2 is a plan view thereof,

Fig. 3 is a cross section taken on the line 33 of Fig. 1, Fig. 4 is a cross section taken on the line'44 of Fig. 1, Fig. 5 is a cross section taken on the line 55 of Fig. 1.

The invention has been shown in the accompanying drawings as applied to a tooth brush, but it will be readily understood from this specification that the invention may be applied equallyas well to brushes of other forms, such as hair brushes, paint brushes, *markingfbrush'es and the like, and I desire therefore ,to be understood "as not intendingto limit myself to; tooth brushes alone.

- *In the drawings, 1 10, i represents an"- ordi i narytooth brush, ha vin'g; aback 11, inwhich the bristles 1'2, ar-e secured-'- and a handle 13*,"

fixedto the tack The handle 13,-ma y be formed-integral with thebackll, ifdesired, *or"itma'y= comprise aw's'e'parat'e piece secured" "thereto, as for instance by means ofri vets 14. j The handle j is preferably concave-con? veil in "'cross'"=section, in order to receivefand accommodate the reservoir} as will fhereafter complishing this purpose.

'The neck'25, communicates withthehollow'stem 22,:and aninternally threaded 'coupling 27, is provided: for se'curing the tube upon said hollowstem 22. In the form ."shown, said hollow 'stem provided upon 1 appear, and the forward end of said handle is bent up with overhan ing flanges 15, that engage with the upper ace of the back 11.

This construction 1s preferably used where the back of a standard tooth brush is used and the handle fitted and secured thereto.

' The back 11, is preferably provided with a lug or projection 18, which, if desired, may

comprise a separate piece, secured thereto as for instance by a rivet 19, and a nipple 20, which extend through the back. The opening or port 21, of the nipple forms part of an L shaped duct or passageway 16, that extends from the bristles and out through 7 the lug 18. Said port 21, communicates with the interior of avhollow stem 22, through a port 23, in said stem. The stem is removably seated in the longitudinal bore 17 which forms part of the L shaped duct 16, 7

and by properly turning said stem 22, the port 23, may be brought into or out of register with the port 21, which leads to the bristles.

Resting in the hollow of the handle is a 30 magazine or tube 24, which is adapted to contain the tooth paste or dentifrice when the invention is applied to a tooth brush, or to contain the substance which it is desired to apply to the bristles when the device is used upon any other kind of a brush.

The tube or reservoir 24, may be of any well known form of soft metal tube, having the usual externally screw threaded neck 25,

through which the contents are forced out by squeezing together the sides of the tube. In securing the tube upon the handle, the rear end of the tube is preferably flattened down and folded around the end of the handle as shown at 26, in Figs. 1 and 2.

This provides a simple form of means for connecting this end with the end of the handle, although it is obvious that various other 'expedients may be provided for acone end with an outwardly projecting flange 28, and the "coupling- 2Z, is provided -'with a flange 29, which overhangs' thefiange 28, of

" the I hollow stein 22 -If desired a washer 30, may be i terposed "between the flanges of the hollow stem and coupling-fto' prevent .Jeakage: The coupling 27 g is screweddown upon the neck 25, of the tube to connect the two parts, and the hollow stem 22, is left free to turn in the coupling. A pin or other projection 31, extends out from said hollow stem and forms a handle by means of which the stem may be turned to bring the port 23, into or out of register with the port 21. A stop is provided for the pin 31, and as shown, comprises a notch 32, formed in the flange 15, of the handle. The paste tube is positively. prevented from any longitudinal movement upon the handle by the seating of the pin 31, in the notch, and consequently is secured thereon against accidental displacement. The folded end 26, of the tube which is wrapped around the end of the handle, assists in holding the ends of the tube and handle together.

In the use of the brush, the tube or reservoir 24, is coupled with the hollow stem 22, by means of the coupling 27, the stem slid into the bore 17, the pin 31, swung down into the notch 32, and the rear end secured to the end of the handle. By lifting the pin 31, and thereby turning the hollow stem 22, until the port 23, registers with the port 21, communication is established between the interior of the tube and the bristles of the brush. By pressing upon the tube near its rear end, the contents may be forced out through the hollow stem, port 21, and in between the bristles of the brush. When sufficient material has been fedto the bristles, the pin 31, is swung. back into the notch 32, thereby closing the port to the bristles and locking the tube to the handle. VVhenever it is desired to clean the brush, the pin 31, is lifted out of the notch and the connected paste tube and hollow stem withdrawn from the bore 17 whereupon water may be passed through the ports in the brush.

I am aware that various alterations and modifications of this device are possible without departing from the spirit ofmy invention, and I do not therefore desire to limit myself to the exact form of construction shown and described.

I claim as new and desire to secure by Letters Patent:
