United States Patent 3,331,093 PRESSURIZED PAINT SUPPLY ASSEMBLY VITEI EXTENSION APPLIEATOR Frank E. Mayden, Springfield, IlL, assignor of one-half to Theresa E. Mayden, Springfield, Ill. Filed Nov. 12, 1964, Ser. No. 410,455 9 Claims. (ill. 575) This invention relates to a novel and useful pressurized paint supply assembly and more specifically to a paint supply assembly including a roller applicator and means for conveying paint from the reservoir to the roller applicator.

The paint supply assembly is specifically adapted to provide a means whereby a roller type paint applicator may be continuously or selectively supplied with desired quantities of paint. The roller applicator of the instant invention includes liquid spray dispensing means supported adjacent the roller applicator and positioned relative thereto so as to evenly spray liquid on the roller applicator when the liquid spraying dispensing means is actuated.

The paint supply assembly of the instant invention includes a plurality of types of roller applicators which are each specifically defined for a particular painting operation.

The main object of this invention is to provide a paint supply assembly of the pressurized type including a paint applicator and means for continuously or selectively supplying the applicator with the desired quantity of paint.

Another important object of this invention is to provide a paint supply assembly including a plurality of paint applicators each designed to perform a specific function and communicated with the pressurized liquid reservoir of the supply assembly by means of a flexible conduit provided for the purpose of conveying paint from the reservoir to the paint applicators. In this manner, the plurality of paint applicators may be selectively utilized as required by a painter.

Yet another object of this invention is to provide a novel means of connecting the paint conveying flexible conduit to the liquid reservoir of the paint supply assembly in a manner such that maximum freedom of movement of the paint applicators is afforded without undue tangling of the flexible conduits communicating the paint applicators with the pressurized reservoir of the paint supply assembly Still another important object of this invention is to provide a pressurized paint supply assembly in accordance with the preceding objects constructed in a manner whereby the entire assembly is readily portable from one location to another.

A final object of this invention to be specifically enumerated herein is to provide a pressurized paint supply assembly with extension applicators in accordance with the preceding objections which will conform to conventional forms of manufacture, be of simple construction, easy to use so as to provide a device that will be economically feasible, long lasting and relatively trouble free in operation.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 6 is a side elevational view of the modified form of extension applicator illustrated in FIGURE 5 illustrating the manner in which the modified form of a paint applicator may be utilized to paint a cylindrical member, portions of the modified form of extension ap plicator being broken away and shown in vertical section;

FIGURE 7 is an enlarged fragmentary vertical sectional view taken substantially upon a plane indicated by the section line 7-7 of FIGURE 6; and

FIGURE 8 is a fragmentary enlarged end elevational view of the modified form of extension applicator as seen from the right side of FIGURE 7 and showing the manner in which the lower applicator portion thereof is removably supported therefrom.

Referring now more specifically to the drawings, the numeral 10 generally designates the pressurized paint supply assembly of the instant invention which may be seen, as shown in FIGURE 1, to include a paint supply reservoir 12 including ground engaging support Wheels 14 and a pressure tank 16 of conventional design which is communicated with the interior of the reservoir 12 in any convenient manner.

The reservoir 12 includes a front depending support leg 13 and a rearwardly and upwardly directed handle 20 for the purpose of supporting the reservoir 12 when the latter is stationary and pushing the assembly 10 from one location to another, respectively.

The opposite sides of the reservoir 12 are provided with pairs of support hooks 22 and the assembly 10 includes a pair of extension applicators generally referred to by the

reference numerals

24 and 26 which may be remova-bly supported from the corresponding pairs of supporting hooks 22.

As can best be seen from FIGURES 1 and 4 of the drawings the paint reservoir 12 includes a flanged outlet neck 28 to which the lower end of an upstanding outlet pipe generally referred to by the reference numeral 30 is swivelly supported by means of a swivel coupling assembly 32. The upstanding outlet pipe includes an upper section 34 and a lower section 36. The lower section 36 terminates at its upper end in a laterally directed and flanged outlet end portion 38 and the lower end of the upper section 34 terminates in a laterally directed end portion 40 including a swivel connection assembly 42 which swivelly connects the lower end of the upper section 34 to the upper end of the lower section for rotation about a substantially horizontally disposed axis extending transversely of the upper and

lower sections

34 and 36.

The upper end of the upper section 34 is provided with a T-fitting 44 and corresponding ends of a pair of flexible paint conveying conduits 46 and 48 threadedly engaged with the opposite end portions of the cross leg 50 of the T-fitting 44.

The other pair of corresponding ends of the flexible paint conveying conduits 46 and 48 are connected to corresponding valve assemblies 52, and 54 of the

extension applicators

24 and 26, respectively. The valve assemblies 52 and 54 include valve actuators 56 and 58, respectively, and to which the inlet ends of a pair of

rigid pipe sections

60 and 62 of the

applicators

24 and 26, respectively are secured.

Each of the

applicators

24 and 26 includes an elongated handle portion 64 from which are corresponding rigid pipe sections are supported by means of suitable double ended clamp assemblies 66.

The

rigid pipe sections

60 and 62 generally parallel the corresponding handle portions 64 and it may be seen that a roller applicator support frame generally referred to by the reference numeral 68 is supported from the end of the handle portion 64 of the extension applicator 26 remote from the valve 54 thereof. The roller support frame 68 is generally U-shaped in configuration and includes a pair of generally

parallel arms

70 and 72 interconnected at one pair of corresponding ends by means of a bight portion 74, the approximate center of the bight portion 74 being fixedly supported from the corresponding handle portion 64 as at 76. The free ends of the

legs

70 and 72 include inwardly directed

stub axle portions

78 and 80, the stub axle portions 78 being fixedly supported from the leg 70 and the stub axle portion 80 being axially shiftable relative to the leg 72 and urged into the extended position illustrated in FIGURE 3 of the drawings by means of a compression spring 82.

A paint roller applicator 84 including a longitudinal shaft portion 86 journalled from the

stub axle portions

78 and 80 and the end of the rigid pipe 60 remote from the valve 54 has a T-fitting 88 connected thereto supported from the bight portion 74 as at 90. A pair of

branch pipes

92 and 94 and adjacent end portions communicated with the T-fitting 88 and have

spray head assemblies

96 and 98 supported from the remote end portions, the

spray head assemblies

96 and 98 also being supported from the bight portion 74 as at 100 and 102, respectively. The T-fitting 88 defines a portion of a third spray head assembly generally referred to by the reference numeral 104 and accordingly, it may be seen that the

spray head assemblies

96, 98 and 104 are disposed in communication with a rigid pipe 60 for receiving paint from the reservoir 12 upon actuation of the valve 54. The spray head assemblies 96, 98 and 104 are positioned beneath the paint roller applicator 84 in a manner such as to direct an upward spray of paint on the roller applicator 84 upon actuation of the valve 54.

With attention now invited to FIGURES 8 of the drawings it may be seen that the extension applicator 24 also includes a generally U-shaped roller applicator supporting frame generally referred to by the reference numeral 110 including a pair of generally

parallel legs

112 and 114 interconnected by means of a generally shallow V-shaped bight portion 116. The leg 112 includes an inwardly directed stub axle portion 118 corresponding to the stub axle portion 78 and the free end of the leg 114 has a generally V-shaped notch 120 formed therein and a pivoted latch member 122 rotatably supported therefrom for movement between the phantom line position in FIGURE 8 of the drawings opening the slot 120 and the solid line position illustrated in FIGURE 8 of the drawings closing the outer end of the slot 120.. The extension applicator 24 includes a paint roller assembly 124 including a stub axle portion 126 on one end which is receivable in the slot 120 and a diametric blind bore 128 at its outer end in which the stub axle portion 118 is receivable. Accordingly, the roller applicator 124 may be removably journalled from the frame 110 of the extension applicator 24 by first inserting the stub axle portion 118 into the blind bore 128 and then moving the stub axle portion 126 into seated engagement within the slot 120 and subsequently pivoting the pivoted latch 122 from the phantom line position illustrated in FIGURE 8 of the drawings to the solid line position illustrated in FIGURE 8 of the drawings.

The end of the rigid pipe 62 remote from the control valve 52 is communicated with a sprayer head assembly generally referred to by the reference numeral 130 and supported from the center of the V-shaped bight portion 116. The sprayer head assembly 130 is positioned to direct a spray of paint upwardly onto the roller applicator 124 and it may be seen from a comparison of FIGURES 3 and 7 of the drawings that the roller applicator 84 includes brush portions 84' defining a substantially cylindrical roller while the roller applicator 124 includes

brush portions

132, 134 and 136. The brush portions 136 define a reduced diameter portion disposed between two larger diameter portions thereof defined by the

brush portions

132 and 134 and accordingly, as can be seen from FIGURE 6 in the drawings the roller applicator 124 is particularly well adapted to apply paint to cylindrical surfaces such as the fence post 140. As can be seen from FIGURE 1 of the drawings the roller applicator 84 is particularly well adapted to apply paint to substantially the planar surfaces.

The swivel connections or

assemblies

32 and 42 enable the flexible conduit 46 and 48 to be shifted in posi-.

tion relative to the reservoir 12 without the conduits 46 and 48 becoming unduly tangled.

Further, it may be seen from FIGURES l and 2 of the drawings that the

rigid pipe sections

60 and 62 are slightly inclined relative to the corresponding handle portions 64 and therefore that the

pipe sections

60 and 62, in combination with the corresponding handle portions 64, provide improved handle means for the

extension applicators

26 and 24, respectively.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
