Application March 20, 1937, Serial No. 132,004 10 Claims. This invention relates to what is generally known as a fountain paint brush. This application is a continuation-in-part of a prior application, Serial No. 70,092, filed March 21, 1936, 5 entitled “Fountain paint brush device.” The chief object of this invention is to provide a fountain brush or like device construction which will eliminate the dipping of the brush into the material to be applied by the brush. 10 Another object of the invention is to provide for the ñowing of the paint or like from the brush in band o1' stream form. Another object of the invention is to arrange l5 the brush such that as the bristles wear the im- mediate supply means for supplying paint to the bristles may be adjusted in accordance with bristle wear. Another object of the invention is to flexibly connect the immediate paint supply means of the 20 brush when desired, so that for certain classes of work (other than :dat Work) flipping of the paint due to bristle exposure of the supply means, is prevented. . The chief feature of the invention consists in 25 the construction of a fountain brush capable of accomplishing the foregoing objects as well as all the objects recited by the aforementioned copending application and the features specifically disclosed herein are in .addition to the features 3.0 disclosed in the before mentioned copending application. Still a further feature of the invention consists in providing a remote control device for the brush and mountable upon the brush to permit 35 the brush operator to hold the brush in anyone of several diifei‘ent manners and yet at the same time have complete control over the paintsupply. Another feature of the invention consists in the addition of flared flexible tips upon the ends 40 of the bristle enclosed flexible paint supplying tubes, which ileXible tips are also bristle enclosed. Another feature of the invention consists in the detachable association of the several parts so 45 that not only can cleaning of the entire brush be effected most expeditiously and efficiently but the ' tive detachable parts are of such character lespec that for replacement purpçses’ when th b e rus h, bristles are worn out, there 1s required only a new _ _ 50 base with the new bristles supported thereby and new tube tips, if necessary. Other features of this invention will be more fully' Sel', ÍOl’th hereinafter in the detailed description. 55 The full nature of the invention will be under-_v (Cl. 15-128) stood from the accompanying drawing and the following description and claims: In the drawing, Fig. 1 is an enlarged central sectional View of a fountain brush embodying the invention, the valve control portion being shown 5 in elevation, the dotted lines indicating the ñnal adjustment possible when the brush is prac tically Worn out. Fig. 2 is a sectional view of the brush shown in Fig. lbut is taken at right angles thereto and 10 on line 2-2 of Fig. l and in the direction of the arrows, said brush, however, being shown pro vided with a remote control attachment. Fig. 3 is a view similar to Fig. 2 and of a modi fied form of brush, the remote control attach- 15 ment being omitted for clearness. In Figs. 1 and 2 of the drawing, I0 indicates a base provided with a plurality of apertures II extending therethrough, the apertures being herein shown in alignment and parallel to each 20 other. A central aperture I3 is also provided. The bristles I4 are suitably secured to the base. This may be of molded rubber, or the like, if de sire-d. The aperture I3 may be threaded to re ceive the externally threaded tubular member I5 25 having the coaxial opening I6 therein. Press-ñtted or molded in the base I0 and posi tioned in the apertures II, are the tubes I1 in ternally threaded as at I8 and terminating in a frusto-conical mouth I9. 30 A head structure 20 includes a chamber 2| and a flange 22, the latter bearing on the gasket 23 of suitable material and interposed between the flange and the base. The head 20 is nested in a well formed by the band 24 suitably secured to 35 and peripherally enveloping the base Ill andy pro jecting in opposite directions therefrom to enclose the bristles adjacent their connection to the base and to form said Well. The head 2e is apertured as at 25 adapted to receive a tubular portion 26, 40 the bore of the latter being internally threaded as at 21 and Deal" its lOWel“ end being DTOVÍdSd With ÈTEHS‘ÉSFSÉ ‘ports 01' passages 23 discharging t0 the Cham er - _ _ The tubular pomo“ 26 Sultably Supports a' 45 thumb Operable Valve 29 and Connects a? at 30 to a tubular handle structure broadly designated by the numeral 3|, the latter terminating in a threaded tubular end 32 which mounts a retain ing threaded Collar. 01. nut 33_ The paint supply 50 is Connected to end 32_ A remote Control arrangement may be asso Ciated with said Valve and the same is illus trated in Fig. 2. It includes an apertured an choring end 34, a hand engageable portion 35, 55 2,127,000 2 the latter portion being channel or U-shaped in cross section and the sides 36 partially em bracing the handle 3|. Portions 35 and 36 are oiîset laterally and outwardly as at 31 and 38, respectively, and thence downwardly as at 39 and 49, and the latter portion merges with the extension 4I of the portion 39. Suitably secured to the interior of portion 31 is a clip 42 and the same is adapted to lie below the head of the valve 29 while the portion 39 lies above the same. The side portions 46 adjacent thereto thus form with portions 39 and clip 42 a four-sided pocket that receives the head. This remote control attachment is readily ap plied to the brush handle by merely removing the nut 33 and telescoping the apertured portion 34 over the exposed threaded end 32 and in this movement registering the remote control device such that- the head of the valve 29 nests in the pocket, as shown in Fig. 2. 'I'hereupon the nut 33 is replaced which secures the handle in position and permits valve control by manipulation of the remote control device. This permits the brush operator to operate valve 29 to control the supply of paint to the bristles, such control being effected by the operator independent of the posi tion in which he holds the brush. This device, therefore, prevents fatigue and does not neces sitate the brush operator always holding the brush in a predetermined position-that is, a position wherein the thumb always must be in registration with the valve 39. It is to be under stood Figs. 1 and 2 relate to the same brush, al though the latter figure shows the addition of the remote control attachment. Reference will again be had to Fig. 1. In this íigure the handle structure adjacent the valve 29 is shown provided with a shoulder 43 and between said shoulder and the embossment 44 on the head 40 is interposed a gasket 45. Slidably mounted in each of the tubes I1 is a flexible tube 46. This tube, as shown clearly in the lower left hand portion of Fig. l, is a double wound spring, the exterior tubular spring struc 45 ture being indicated by the numeral 46a and the interior by the numeral 46h. The upper end of the tubular portion supports an externally thread ed tubular head 41 having a. diametrical slot 48 therein for screw driver engagement. If desired, 50 ’the connection between the tube 46 and the tubu lar head may be of rotative character. In normal operation, however, the two are rigidly associated together. In either event, the rotation of the tubular head secures axial adjustment of the tube 46. The limit of such adjustment is shown by the dotted lines in the left hand portion of Fig. 1 about the middle of the ligure. The lower end of the tube 46 is provided with a metallic tip having the tubular portion 49 and 60 the ñattened ilared portion 56. The same sup ports and discharges into an elongated flexible tip structure having the tubular portion 5I and the flattened portion 52. A split ring or lock 53 secures the metallic tip to the end of the tube 46 and when thus secured, it will be obvious that the flexible tips are simultaneously secured to the tubes. Whenever it is desired to yieldingly associate the ilexible tubes together for substantial unit 70 movement and prevent undue relative movement therebetween, the purpose for which will be read ily apparent to painters, there is provided a ñexi ble connection. This may be merely a leather strip 54 apertured at 55 and the tubes 46 are posi tioned inthe apertures. Thus, all the tubes 46 are connected together for relative unitary move ment, although relative independent movement within the limits 0f the tying or connecting de vice is permitted. Each of the apertures II is provided with a Cn tube I1 and each tube I1 supports a tubular structure such as last described, provided with the ñexible leather tip 52. The central tubular supply means is mounted slightly differently and reference will now be had to substantially the central portion of Fig. 1. Tubular member I5 has its coaxial opening I6 internally threaded in the same manner as the interior of the tubes I1 are threaded as at I8. It also is externally threaded near its upper end 15 as at 56 and is threaded into a nut 51 embedded or molded in the chamber exposed face of the base I6. A nut 58 is threaded upon the opposite end 59 of the enlarged portion I5 and bears against the bristle supporting face of the base. 20 Thus, member I5 is rigidly locked in and to and supported by the base I6. The tubular extension 59 terminates at its lower end in a frusto-conical portion 60, portions 59 and 60 being substantially similar to the bristle exposed portion of tube I1 25 and its frusto-conical end I9. The interior of extension 59 is threaded as at 6I similar to the threading I8 in tube I1, so that one of the flexible tube units 46 with its tubular threaded member 48 may be associated therewith and with mem 30v ber I5. » Somewhat similar to the anchorage between the handle and the base shown in the before men tioned application, there is herein illustrated an anchorage as follows: Portion I5 includes an 35 opposite tubular extension 62 which may or may not be internally threaded, as desired. It is, however, externally threaded as at 63 to receive the internally threaded portion 21 of the tubular portion 26. Member I5 by reason of its threaded 40 engagements with the respective nuts 51 and 58 is non-rotatably mounted in the brush base I0 and when the tubular portion 26 of the handle structure is inserted in the aperture in the head 20 and threadedly engages the threaded exten 45 sion 62 of the member I5, the handle and the base are drawn together with the gaskets 45 and 23 interposed therebetween and with the head structure 20 between the gaskets. Thus, a closed and relatively sealed supply chamber is provided, paint being supplied through the tubular handle and discharging to the tube I1 by way of the chamber`2l fed by ports 28, the central tubular structure being fed direct from the handle. From the foregoing it will be obvious that, as the several threaded members 41 are grad ually elevated toward the base I0 to retract the discharge ends of the tubes in accordance with bristle wear or for flow adjustment and smooth ness of operation, the life of the brush is de terminable by the wear to which the bristles are subjected and the ñnal limit of tube adjustment. For cleaning purposes, the chamber may be readily opened by disconnecting the handle from the base which exposes the interior of the handle for cleaning purposes, the head exposed portion of the base for cleaning purposes and the head passage and chamber. The metallic tip and the ñexible tip may be readily detached from the free end of each ñexible supply tube, and then if the connecting member 54 is employed, it may be removed from all of the tubes. Thereupon each of the members 41 together with the tubes 46 may be unthreaded from the tube I1 and these tubes 46 cleaned. Then the tubes I1 and 59 as 2,127,000> Well as the bristles may be cleaned. In this way the entire brush may be made ready for subse quent use with a different color or paint ma terial. v By the terminology “paint” herein, the same is used broadly and refers to any liquid surface covering material that may be applied like paint, even though not specifically of paint character, such as for example, enamel, and the like. In Fig. 3 there is illustrated a modiñed form of the invention and for clearness only a portion of the handle is illustrated and the remote con trol attachment intentionally has been omitted. In this disclosure, there is illustrated a base H5 15 to which is suitably secured bristles IM and the band |24 is suitably associated therewith. A head member |20 includes a chamber |2|. The head member bears on a gasket |23 and bear ing on the head member is a gasket |45. The handle |3| having the valve structure |29 in cludes the compression shoulder |43. The brush shown herein is not a wide flat brush but a single feed brush, the base HB being pro vided with a bore H3 therethrough and having 25 suitably secured thereto the nut |57. The tubu lar member ||5 has threaded connection with the nut |51 and is clampingly associated with the base by the nut |58. The tubular member ||5 includes the tubular extension |59 having 30 the frusto-conical end ISB receiving the flexible tube |46, the latter supporting the metallic tip |50 secured as at |53 and supporting the flexible tip |52. The member || 5 includes an opposite exten 35 sion |62 which is externally threaded .and is adapted to have threaded connection with the interiorly threaded extension on the handle |3|, which extension is substantially identical to that shown at 26 in Fig. l. It is, of course, to be un» 40 derstood that threaded within the tubular por tion |59 is the threaded member 41. While the invention has been illustrated and described in great detail herein, the same is to be considered as illustrative and not restrictive 45 in character. The several modifications herein illustrated and/or described as well as others which will readily suggest themselves to persons skilled in this art, are all considered to be within the broad scope of the invention, reference being 50 had to the appended claims, although the sub ject matter common to the present invention and the invention disclosed in the before mentioned copending application is specifically disclaimed herein, because it is claimed in the copending 55 application.
