JACKIE. PYRTLE, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR TO SERVICE PRODUCTS MANUFACTURING CO., OF CHICAGO, ILLINOIS, A CORPORATION ILLINOIS.

FOUNTAIN BRUSH.

To all -w/i0n'1 it may concern:

Be it. known that I. JACK E. 'P'rn'rLn, a citizen of the United States, and a resident of San Francisco. county of San Francisco, State of Calitornia, have invented av new and useful Fountain Brush of which the following a specification.

This invention relates to tountain brushes wherein the handle forms a receptacle for whatever fluid it is desired to use in the brush, and particularly to the type oi such brushes which are adapted to hold volatile cleaning liquid such as benzol and the like for the cleaning of typewriter typeyremovi119; spots from clothing and other cleaning purposes.

The objects of my invention are to effect improvements in a brush ofthis kind result ing in utmost simplicity and consequent cheapness ot production. while at the same time providing: a serviceable article having a reliable control for the liquid feed to the hairs of the brush, a perfect closure, an easily removed tip so that the liquid may be ejected freely to any spot without the medium of the hairs it desired, an easily refilled reservoir, and a sight indicating reservoir for the fluid.

I attain the objectives outlined by the fountain brush structure shown in the accompanying drawings and in which:

Figure 1 is a perspective view of my complete brush as fitted with a transparent or glass handle reservoir.

Figure 2 is an enlarged central section of the upper portion of the brush showing its interior construction.

Figure is a cross section of Figure 2 along the line 3*?) thereof showing the liquid teed.

Figures 4 and show optional methods of securing the removable end to the reservoir handle.

In further detail the drawings show at (1) a hollow handle or reservoir for the liquid, in this illustration a gr] ass tube forms the handle so that the liquid (2) is visible thus indicating at a glance whether the reservoir is full Or empty.

The lower end (3) of the tubular handle is closed and at the upper end is fitted a cork or other stopper (.1) having a. metal gripping flange (5) and having an extension carrying a ferrule forming a holder for the brush hairs (7).

In Figure? the interior arrangement is shown and the ferrule- IlS seen to be closed at the lower end (S).with a threaded tube (9) extending into the ferrule and which tube Y is closed small plug (10). r r The brush hairs (7) arc held in the ferrule by the latter, being crimped or contracted at the outer edge shown at (11).

The ferrule supported by engagement of.

its threaded. tube (9) with an exteriorly threaded stem extension (12).. or feed pipe, passing' through the stopper (4.), and the feed pipe hold securely to the stopper by a washer (13) riveted to one end and clamped by the flange (5) which is threaded over the pipe.

lVit-hin the pipe is a liquid passage (14) terminating; at the upper end in a very small orifice (15). The extreme upper end of the feed pipe is rounded as shown at (1(5) so that UPOUSCI'OWlIlQf the :terrule down over the pipe, the end impinges the block (10) and thereby closes oil the small orifice (15).

Small liquid feeding: passages extend from between the tube space and the hairs of the brush either taking the form of perforations (17) in the tube or the form of slightly flattened sides ot the plug '(10) shown at (18), see Figure 3. so that when the ferrule is unscrewed slightly to uncover the orifice the liquid will run through the passages and into the hairs ot. the brush. 1 To get a quick action the brush may be given a violent shake or two to start the flow.

It is desirable that the ferrule screw snugly over the threads of the extension stem (12) so that the liquid will not back up along the threads during; use.

'No air vent lSOldllllllll) necessary in the at its inner end by a reservoir as the cleansing liquids used are through the hairs ot the brush.

Instead of the stopper fitting within the hollow handle as described, it may take the torm of a sleeve (19) surrounding the handle and har ing a gasket ring (20) interposed as shown in Figure 4-, or itmay be screwed to the outside of the handle as shown. in Fig wte 5 in which latter case it would be desirable that the bemade of a metal tube.

Having thus described my invention it will be seen to effect the desired elejjects inan extremely simple and cheap Way and it is the construction shown including; reasonable modifications as may come Within the spirit of the invention. that I wish to cover projecting therefrom, a bristlecarryin'gc U1- bular element surrounding and securing-the ing over the pipe, said. socket having a stop adapted-E to abut and close the: end of the pipe upon screwing the element, and a port 20 from. the socket to the bristles adjacent the stop.

2. A fountain hrush coinprising a tubular reservoir handle with a stop-per frictionally fitting one end, a pipe threadedly engaging 25 and extending through the stopper and clamped there-against by nuts on the pipe at opposite sides of the stopper, a brush head having av retaining ferrule and screwed on thepipe, and a valved port between the pipe 30 and brush head closed or' opened by screwing-the ferrule;
