CHRISTOPHER A. GARVEY, OF CLAYTON, MISSOURI.

FOUNTAIN-BRUSH.

Specification of Letters Patent.

Patented Dec. 18, 1917.

Application filed November 18, 1916. Serial No. 132,109.

To all whom t may concern.'

Be it known that I, CHRISTOPHER A. GARVEY, a citizen of the United States of America, a resident of Clayton, in the county of St. Louis, State of Missouri, have invented certain new and useful Improvements in Fountain-Brushes, of which the following` is a full, clear, and exact description, reference being had to the accompanying drawing, forming a part of this specilication.

My invention relates to a fountain brush having an automatic regulating valve for controlling the flow of iuid to the brush. Prior to this invention fountain brushes have been provided with regulating valves Vunder the control of the operator, the ow of ink or other fluid being regulated by actuating va valve opening device, or by imparting an unusual movement of some kind to the brush. In using these prior devices, the flow of fluid is varied or predetermined by movements requiring the judgment and attention of the user. When a brush of this kind is moved rapidly over the stencil or other article to be marked or painted, the fluid will low rapidly from the` brush tip,

- Aand-in this event the fluid should iow at a correspondingly rapid rate'from-the reservoir to the brush. If the brush is moved slowly yover the stencil, or other article,- the uid will pass from the brush tip at a relatively slow rate of speed, and the flow from the reservoir should beregulated accordingly.

In othe'r words the best results may be obtained by regulating the flow of fluid in accordance with the speed of thebrush. In using the prior device, the rate of flow is under the control of the operator, but it is veryv difficult to predetermine just how fast or how slow the ink or other fluid should' flow. In actual practice no entirely satisfactory flow can be obtained for the reason that thebrush is continually fin motion, some strokes being very lrapid and others quite slow, so an adjustment suitable for the rapid strokes will cause aneXcess of fluid to flow to the brush during the slow strokes.. Moreover, the valves in the prior devices are usually actuated intermittently,

` whenever the operator notices that the brush is too dry, and as a consequence, the brushf is usually provided with either too much, or not enou h, of the fluid.

There ore, one ofthe objectsof the present invention is to provide a fountain brush and an automatic regulating valve for controlling the flow of iuid from the reservoir to the brush. In the preferred form of the invention, the regulating valve opens automatically in response to the movements which the user naturally gives the brush. The flow of ink is varied to compensate for variations in the speed of the brush. If rapid strokes are made, a correspondingly rapid flow of ink will be required, and the regulating valve will be actuated automatically to obtain this result. When the brush is operated slowly, the `flow of inkwill be decreased by the automatic movements of the' valve. The structure I have shown also includes means for retaining the automatic valve in its closed position-when the brush is not in service. j

With the foregoing and other objects in view the invention comprises the novel construction, combination and arrangement of parts hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown the preferred em-I tion, illustrating 'a fountain brush cony structed in accordance with the invention.

Fig'II is a section on line II-II, Fig. 1. Fig. III is an enlarged fragmentary section showing the automa-tic valve.

To illustrate the preferred form of the invention I have shown a fountain brush comprising a reservoir 1 adapted to receive ink or other iiuid, a discharge member 2 having a passageway 3, and a brush tip 4: secured to said discharge member. The brush tip may be made of bristles, felt, metal, or any other sui-table material.

A valve chamber 5 is provided with `a concave seat for a valve 6. 7 designates a stop member screwed into the upper portion of the discharge member 2, and adapted to limit the movements of the. valve 6. This stop member has a central opening which is in constant communication with the valve chamber 5 and reservoir l, the lower portion of said opening beingy flared to constitute anvabutment face for the valve. 6. A

helical compression spring 8, seated on the upper face of the valve 6 extends into thew central opening in the stop member 7, and if desired, this spring may be securedat its ends to said valve and stop member.

Lugs 9, extending upwardly from the stop member 7 may be grasped to facilitate the adjustment of the stop member. Itwill be apparentthat this stop member may be adjusted in the threaded upper end of thinJ discharge member 2, for the purpose of regulating the movements of the valve 6, at the same time varying the compression of spring 8.

The valve 6 is metal ball, and the restoring spring 8 is preferably made of line wire. When the brush is at rest, the spring 8 holds the ball valve in a slightlydepressed seat at the upper end of passageway 3, thus closing sald passageway to prevent leakage of iuidA from the reservoir. It will be observed that the heavy ball valve 6 is looselysupported on the concave face of the valve chamber, and that saidV valve 1s free to move 1n vari- A ous directions 1n responseto movements of lthe fountain b-rush.

When the brush is in service, the valve moves continually, the degree of movement imparted to the valve depending upon the speed of the brush. lf rapid strokes are made the` ink should be permitted to flow rapidly, and the valve will move automatically to positions wherein it will not materially obstruct the flow Aof ink. If the ybrush is operated slowly, the valve will move only slight distances, and the ink will then iiow slowly to the brush. From the foregoing it will be understood that thel ball 6 operates automatically in response to the movements which the operator naturally gives the brush; andrit regulates the flow of ink so as to compensate for variations in the speed of the brush.

preferably a large, heavy, v

:gamelle f being loosely supported and free to open automatically in response to the movements to which the article is subjected in service,

the movements of said automatic regulating valve.

2. A fountain brush comprising a ,reser- Voir vprovided with ya discharge passageway, ja brush member adapted to receive the Huid discharged through said passageway, said passageway including a valve chamber having a concave valve seat, an automatlc regulating valve 1n the Lform of a ball mounted on said concave valve seat and movable transversely of said discharge passageway to regulate the flow of) fluid therethrough, an `adjustable stop device screwed into said valve chamber, said adceive a portion of. said automatic regulatin valve, and a spring interposed between an y7o justable stop device being recessed to reseated` against said valve and the adjustable stop device, said valve being loosely supported and free to move,v in various directions- 'on said' concave seat in response to movements -to which the article is subjected in service, thereby Iautomaticall regulating the flow of Huid to thebrus member, the side wall of the recess in said stop device being located adjacent to said valve toy constitute a stop for limiting the movements ofthe valve, and said stop device being adjustable to mo've said wall toward and away from the valve."
