Unitcd States Patent 3,441,355 PRESSURE-SUPPLIED PAINT ROLLER Roger S. Brown, 401 Poplar Drive, Thomaston, Ga. 30286 Filed May 12, 1967, Ser. No. 638,121 Int. Cl. B44d 3/28, 3/00 US. Cl. 401219 4 Claims ABSTRACT OF THE DISCLOSURE A valved reservoir provides a handle which has a pickup hose at its trailing end and a delivery hose at its leading end. An L-shaped rod provides a shaft and shank, the latter being joined to said leading end. Usual type roller rotates on the shaft. A curvate shield and manifold unit is adjustably bracketed on the shaft. The manifold receives pressurized paint, has orifices which feed paint through ports which are aligned with plurality of diagonal slots formed distributively in a spreading plate in wiping contact with rollers applicator sleeve.

Background of the invention It is old in the art to force paint from a pressurized source of supply through a hose into a hollow handle and to deliver the paint under pressure through a valved line or hose to a shield equipped with a manifold and, as a matter of fact to so construct the shield and manifold that the paint will be spread on the roller-sleeve for distributive application to a wall or other surface which is being painted. This combination of admittedly old features is shown in the paint applicator roller of the patent to Magoon 2,654,107 and also in a slightly more significant and broadly analogous patent, namely, Whitfield et a1. 2,898,618.

Summary Briefly, the improved combination herein comprehended is characterized by an elongated handle-forming reservoir capable of dispensing a supply of paint under pressure and having a pickup and supply hose communicatively joined to a trailing end of said handle, the leading end of said handle having a communicable paint delivery hose attached thereto, a rod providing a roller journal or shaft in front of and at right angles to said leading end, said rod having a rearwardly laterally directed shank at one end, the rearward end of said shank being axial with and operatively joined to the leading end of said handle, a paint applying roller mounted for free rotation on said shaft and peripherally covered with an absorbent applicator sleeve, an elongated concave-convex shield commensurate in length with the length of said roller and having its concave side opposed and proximal to and having wiping 3,441,355 Patented Apr. 29, 1969 contact with a cooperating segmental surface portion of said sleeve, said concave side having paint distributing slots and complemental ports registering with said slots in a manner to effectually soak rotating surface portions of said sleeve with ample ready-to-use paint, an elongated manifold fixed atop the crest of the convex side of said shield and having paint dispensing orifices communicating with said ports and slots, means operatively mounting the ends of said manifold on the respectively coacting end portions of said shaft, and a paint inlet nipple carried by said manifold to which the aforementioned paint delivery hose is communicatively connected.

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.

Brief description of the drawing FIG. 1 is a view in perspective of a pressure supplied paint roller constructed in accordance with the objectives and principles of the present invention.

FIG. 2 is a view on an enlarged scale looking at the front of the roller construction and with a portion at the left broken away and appearing in section to emphasize certain of the details of construction.

FIG. 3 is a bottom plan view of the improved shield and manifold unit and which emphasizes the slotted liner or plate which features the oriented and coordinated diagonal spreading and distributing slots.

And FIG. 4 is an enlarged detail section taken on the plane of the section line 4-4 of FIG. 2 looking in the direction of the arrows.

Description 0f the preferred embodiment Referring now to FIG. 1 the numeral 6 designates the elongated cylindrical hollow barrel which constitutes a handle and also a reservoir whose trailing end at the right is provided with a neck 8 for the attachment thereto of a hose 10 which in practice is connected with a source of supply in the manner shown diagrammatically in the aforementioned patent to Magoon 2,654,107 and also (Fig. l) of Whitfield et al. 2,898,618. The forward or leading end of the reservoir is tapered and reduced to provide a generally conical neck 12 to the right of which a suitable control valve 14 is provided. This neck in turn is provided with an auxiliary neck 15 with which a delivery hose 16 of the type illustrated is connected. The neck 12 is also provided with a terminal enlarged head 18 which carries a substantially L-shaped rod member 20. One leg or limb provides a shank 22 and the other laterally directed leg provides an axle or shaft 24 on which the hub 26 of the paint roller 28 is mounted for free rotation in the manner suggested in FIG. 4. The roller 30 has its surface provided with an absorbent sleeve 32.

The essence of the present contribution to the art resides in the novel means which is adjustably and detachably bracketed on the shaft 24 and which functions to spread and distribute the pressurized paint. This means comprises an arcuate or concave-convex elongated first plate which is here designated as a shield 34 and which cooperates with a quarter-segment of the freely turnable paint roller 30 as brought out particularly in FIG. 4. The leading lengthwise edge at the left in FIG. 4 is denoted by the numeral 36 and the rearward or trailing lip or edge is denoted at the right as at 38. The median portion between these two lips or edges 36 and 38 is provided with longitudinally spaced ports 40 which are arranged in a straight row. These ports are located so that they align and register with orifices 42 provided in the underneath or bottom part of the complemental tubing 44 which, more specifically, provides and constitutes the aforementioned paint delivering and distributing manifold. It should be noted that the tubing is slightly longer in length than the shield and that the end portions 46 project beyond and overhang the adjacent transverse ends of the shield. Then, too, these end portions are open in a manner to accommodate plugs 48 which as shown in FIG. 2 carry a screw-threaded fastener 50 and an accompanying washer 52. A first bracket 54 is provided at the left as shown in FIG. 2 and it has its lower end portion 56 suitably attached as at 58 to an end portion of the roller supporting shaft. The upper slotted end portion 60 of this bracket is detachably and adjustably fastened to the means 48 and 50. A similar construction is found in the second or complemental bracket 62 at the right. This is to say the bracket has a lower end portion 64 which is provided with a cleat 66 and fasteners or retainers 68 which are arranged and function to secure the bracket and cleat to the bent end portion 70 of the aforementioned shaft. Hereagain the upper slotted end portion 72 is connected to the assembling and retaining members which in this instance are the same as at the left and are therefore denoted by the same reference numerals 50 and 52. It follows that the combination shield and manifold, as a unit, is detachably and adjustably mounted on the shaft whereby the concave or underneath side of the shield fittingly applies itself to the sleeve or applicator 32 in the manner illustrated in FIG. 4. To the ends desired the concave side is provided with spreading and distributing means for the paint. More specifically the means comprises an arcuate elongated plate 74 which is superimposed upon and fixed to the coacting surface of the shield. This plate provides a liner and is novel in that it is provided with a plurality of spaced parallel angularly or diagonally disposed paint receiving and distributing as well as spreading slots 76. The slotted construction is shown in FIG. 3 wherein it will be observed that the slots are approximately as long as the width of the liner plate 74 and that they are in close spaced parallelism and that, what is more important, the aforementioned orifices 42 and ports 40 are lined up with the median portions of the slots. Consequently, when the paint is flowing under pressure it is distributively spread and applied to the roller in what is believed to be an evident manner. It follows that the invention well serves the purposes for which it is intended, that the features and advantages and the manner of use, being self-evident, a more detailed description is deemed to be unnecessary.

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.
