FOUNTAIN-BRUSH.

Specification of Letters Patent.

Patented Jan. 2, rare.

To all whom it may concern V Be it known that I, JACQUES J. HARDIN, a citizen of the United States, and a resident of Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Fountain- Brushes, of which the following is a specification.

My invention relates to fountain brushes. Its principal object is to provide a simple, cheap, durable and effective form of device by which a liquid may be continuously sup.- plied as desired upon the brush proper from a self-contained reservoir. A. specific object is to improve, simplify and render more effective the brush holding means in fountain brushes, and to improve the flow of liquid upon the brush. A further object is to provide means for easily charging the receptacle. Further. objects and advantages will appear hereinafter. y In the accompanying drawings, which form a part of this specification, I have. illustrated a preferred form and several modified forms of one type of brush device embodying these improvements. In these drawings Figure 1 is a medial vertical section lengthwise of the complete device in a simple form; Fig. 2 is an enlarged View of the end portion of Fig. 1 showing the spring valve thereof somewhat extended; Fi 3 is an enlarged view showing a modified form of connection between the brush proper and the liquid receptacle, and also showing additional brush holding means; Fig. 4 is a broken longitudinal view, largely in section, showing piston means for refilling the receptacle; and Fig. 5 is an en larged sectional view of the end portion of the preferred construction and arrange: ment of parts in the specific type of brush device shown.

In all of the figures the receptacle lO may be of metal, glass, fiber, composition, orof any other suitable material. As in the form illustrated, the device is intended as a marking brush or one for applying any suitable liquid, such as paint, oil, medicaments, etc., in the manner of an ordinarypaint brush; the hollow cylindrical body portion or receptacle 10 is relatively'long and narrow so as to be readily. graspable by the hand. A readily removable cap 11, for cleaning and refilling purposes, is held fricztionally in one end, as in Fig. 1,.or, where a piston is employed, preferably a screw threaded cap 12, as in Fig. 4:, convenient for assembling or cleaning the device, is employed. The brush proper 14:, in the form illustrated, is of bristles or the like,

and is preferably substantially circular in preferably all the way around the circumference or periphery of the outermost turn or turns thereof, as at the annular line 17, thus making a tight joint between the end piece 16 and the spring. The. smaller or innermost end of the spring 15 is secured upon the brush proper 14:, preferably by simply winding the same tightly thereon for several turns of the spring, such winding being sufficient to hold the brush in the desired position. Ordinarily, the brush proper 14. should first be wound with cord or wire, as 18, so that it may be more easily handled when applying the spring 15 thereto, as well as to insure the desired security of the bristles. A cap 20 frictionally held on the end piece 16 maintains the brush proper from drying out objectionably as well as providing the feature of cleanliness to the brush proper and to other objects when the entire device is laid away.

In Fig. 3 I have shown the spring 15 as secured upon the annular brush holding device or end piece 22, which is shown as screw threaded into the container or receptacle 10 for ready removability, while in the other figures the end piece 16 is simply frictionally held by a tight fit at the joint 23. i

It will be noted that the turns of the spring 15 are normally tightly one upon the other; that there is a tight joint between the spring 15 and the surrounding container intermediate the brush proper 1eandthe are at the annular line 17, and also a tight joint being a Wall through which the liquid may not flow when in the normal relative position illustrated in Figs. 1, 3 and 4.' When,

however, pressure is applied to the end of the brush proper 14, as when it is desired to do painting or to apply to a surface the contents of the container 10, the brush proper 14 is forced inward, that is, farther into the body of the receptacle 10, the turns of the spring l5thereby becoming separated, as shown in .Figs. 2 and 5, whereby the liquid may flow between these turns and upon the brush proper. It will be noted that the brush proper is loosely positioned in the container 10, or'its end portion 16 or 22,'being spaced from the walls thereof at the open" end, as at 17; and it will also be observed that the brush is spaced from or is in loose relation to the turns of the spring 15 except at the innermost end thereof. The liquid in the container 10 may therefore readily flow outward upon the exposed portion of the brush proper 1a and be available for application.- Inusing the device it will naturally be in a more or less upright position and the liquid will flow by gravitation outward upon the brush as required, the pressure of the brush upon the surface being painted or otherwise treated opening the valve and permitting the flow to take place. As soon as the pressure of application is removed the spring 15 returns to its closed or normal position, stopping the flow.

In Fig. 3 I have'illustratedan auxiliary helical spring 25 secured as at 26 to the end piece 22 and taperin forward to the turns at 27, which turns bind more tightly the brush proper 14; and maintain the bristles or brush elements thereof against objectionable spreading when it is desired to have the end of the brush relatively small, as for marlringlettersupon boxes or for similar uses. The auxiliary spring 27 has the additional function of rendering the brush 14: more stifl so that the application of pressure at the end thereof will more readily communicate' to the spring 15 the desired valveopening pressure; and it has the further function of providing a feeding device or holder for the liquid flowing outupon the periphery of the brush" 14 at that portion encompassed by the spring 25. In practice the liquid is maintained by the spring 25 in'a readily'available quantity just'above the operating end. portion of the brush proper 14, and when the device is in operation the inward movement" ofthe'brush let causes the turns of the spring 25 to come closer together squeezing out some of the liquid contained thereamong and which then flows upon .the exposed portion of the brush proper. At the same 'timeadditional liquid ffows out of the container 102 upon .the

.spring .25 and when the operating: pressure is removed (which pressure is intermittent as stroke upon stroke is made) the spring 25 eXpands longitudinally and the new supply of liquid is-held about its turns without running freely upon the brush 1%. The turns o'fthe spring 25 are preferably somewhat closer together near the smaller end thereof forming a sort of pocket for the liquid. V V

In Fig. 4: a piston 28 on the rod 29 having a finger piece, such asthe eye 30,-enables the operator to recharge the device by merely inserting the brush end thereof into a can containing the liquid and drawing the piston 28 toward the cap 12, the spring 15 giving wayunder the suction pressure and modate slidingly the sleeve ortube 35 hav- 'ing its inner end enlarged as at 37 to prevent retraction of the tube. As'the brush 14: wearsaway, or to provide-alarger or smallerexposed portion of the brush proper according to the work 111 hand, the tube 35 .may be moved as desired.

It maintains the bristles from spreading, stiffens the brush proper. in its longitudinal direction, and also serves to control the liquid flow upon the operative end of thebrush. The brush 14. is loosely movable inward and outward in thetube 35, but as the bristles are held fairly closely together, the liquid among the bristles is held by capillary at traction so that it does not ooze out upon the exposed end of the brush proper except as drawn there by use.

While I have illustrated a preferred embodiment of these improvements, and have shown certain modifications of the device as a whole, the invention'is not limited to what is specifically illustrated and described, and reference should. be had to the appended claims to determine what I contemplate as being included in the improvements herein set forth. A

I claim:
