June 4, 1957 H. A. SCHUELER PAINTING ROLLER Filed Jan. 13, 1955 INVENTOR. HENRY A.SCHUELER ATTORNEY United Sttes PAINTING ROLLER Application January 13, 1955, Serial No. 431,577 3 Claims. (Cl. 15-239) This invention relates to painting and decorating, with particular reference to a roller for spreading paint or other coatings, liquid or semi-liquid, or impressing or stippling a design on a fiat surface.

The principal object of my invention, generally considered, is to provide painting equipment comprising an improved paint roller applicator for spreading paint evenly over a desired surface.

Another object of my invention is to provide a paint roller device comprising a rod formed with a handle portion, an axle portion disposed at an angle thereto, a roller with a paint absorbent cover, and provided with bearing members rotatively mounted on said axle portion, cap members and a pair of spacer bars extending rigidly from one cap member to the other, the ends of which are respectively secured to each other and to said cap members by said bearing members acting as hollow rivets, each spacer bar having outwardly embossed, longitudinally extending, ribs adapted to press into and bitingly engage the inner surface of the roller cover to hold it firmly in place during use.

A further object of my invention is to provide a paint roller with connecting members extending longitudinally thereof and arranged to firmly engage the internal surface of its cover between its ends, so as to hold it in position.

These and other objects and advantages of the invention will become apparent from the following specification taken with the accompanying drawings. In the drawings wherein like reference characters denote like parts in the several views:

Figure 1 is a side elevational view of a paint roller embodying my invention.

Figure 2 is a transverse sectional view on the line I[-Il of Figure 1, in the direction of the arrows.

Figure 3 is an elevational view, with parts in axial section, of the roller head comprising end caps and spacer bars which hold the roller cover or hollow cylindrical paint-carrying portion, a fragmentary part of which is shown in axial section.

Figure 4 is a transverse sectional view on the line lV-lVof Figure 1, in the direction of the arrows.

Figure 5 is a fragmentary axial sectional view on the line V-V of Figure l, in the direction of the arrows.

The present invention involves structural refinements in a paint roller for the application of paint or other coating liquid or semi-liquid and/or for impressing or stippling a design upon a fiat surface. The roller device of my invention is so constructed that the head may carry a removable pile roller cover. That is, the cover is easily removed for cleaning or discarding purposes, while during use it is held-tight enough so that undesired displacement is avoided. This ease of replaceability, in combination with desirable structural features hereinafter described, are important features of the invention.

Referring to the drawings in detail, like parts being designated by like reference characters, there is shown a roller painter device generally designated 10, and having a combination handle and axle member formed from atent O 2,794,202 Eetented June 4, 19 57 2 a desirably steel rod 11. The free end of the handle or hand-adjacent portion of this rod 11 is provided with a desirably wooden handle or hand grip 12, of a shape oval or elliptical in cross-section, as shown in Figure 4, to comfortably fit a users hand, and from which the rod extends straight a convenient distance. The rod is then shaped or bent at approximately a right angle, providing a straight portion 13., It is then shaped or bent again at a right angle, to form aportion 14, generally parallel to the portion to which the wooden handle directly connects. The rod is then shaped or bent at a right angle, or so as to be generally parallel to the portion 13, to form an axle or. journal portion 15. This portion 15 has mounted thereon a paint roller head, generally designated 16. It is also,

provided with a stop member or portion 17 which may be crimped or otherwise secured to the axle portion 15', to limit movement of the roller to the right, as viewed in Figure l, as by serving as an abutment for the adjacent bearing member thereof. Movement to the left is limitedby the attaching screw 27 threaded into the end of the axle portion 15, as shown in Figure 5. i

The paint roller head or frame structure 16 has a paint-dispersinghollow cylindrical cover IPOI'lllOIl 18, which may be formed ofac onvenient length and diameter depending upon the area to be painted and the depth of the pile thereon. This cover portion 18 is slidable and tightly held on the roller, head 16. It is desirably formed as a core 19, covered by a fabric 21 possessing a pile of dynel, nylon, oran or similar synthetic or naturalmaterialwhich holds a desired amount of paint or other The depth of this pile may be short or coating material. long, depending on the type of coating to be used The core 19 of the roller cover is desirably formed of resin-plasticdmpregnated heavy paper tubing which will not absorb or be aifected by paint, and will not disintegrate, crack, rustor dissolve throughout a normal life.

A suitable material is that sold by the Cleveland Container;

Corporation, Cleveland, Ohio, under the name of Cleve lite? grade BE tubes. However, 1 do not wish to be limited to the use of this material. The fabric 21 is cut to a desired size and fastened .to the core portion in any desired manner, asby means of a suitable adhesive, preferably in a spiral fashion. The spiral winding of the fabric is employed to eliminate undesirable breaks in its continuity.

The roller head 16 comprises a pair of spacer members or bars 22, desirably formed of light metal such as aluminum, .032 inch thick, channeled as illustrated, and provided with longitudinal corrugations 23 intermediate the ends thereof. These corrugations may protrude outwardly from the normal surface of each bar, a distance of about one-sixteenth inch or .062 inch, and be rounded in-outline. In the present embodiment I show five of such corrugations on each spacer bar, evenly spaced about 18 degrees. The whole circumferential dimension of each bar may be about degrees, as illustrated. As will be seen from Figure l, the corrugating of the bars contract them in width slightly between their ends. The, ends of said-bars are flanged inwardly or bent toward one another, leaving the portions therebetween a convenient length, such as about 6 /2 inches, overlapped, and connected to end caps 24. These end caps 24, are also desirablyformed of aluminum of the same thickness'as the barsw They comprise centrally apertured circular end portions, desirably dished inwardly slightly around their apertures, and hollow cylindrical flanges desirably of uniform length around the'periphery and extending toward one another. The end flanges of the spacer bars and theend caps are secured 'togetherby means of bearing members 25.

These bearing members are each desirably formed of ayroanoa a non-rusting cuprous metal such as bronze or brass, apertured to receive the mounting axle portion 15, headed on the outer end, as indicated at 26 to engage at the one end of the roller the abutment 1'7, and .at the other end the attaching screw 27. The other end of each abutment is upset or riveted over after assembly of the parts, as indicated at 28, to cause said bearing members to function as hollow rivets connecting the'en'd caps 24 to the adjacent flanged ends of the spacer members 22, over which said end-caps telescope.

As will be seen in Figure 3, the spacer bars 22 not only have their ends bent at approximately right angles to overlap one another and receive the-connecting bearings, but they are ofiT-set slightly inwardly, as indicated at 29, so that they provide indentations receiving the flanges .31 of the caps 24. In other words, the outer surfaces of the flangesfilare desirably at the same radius from the axis of the roller, as the uncorrugated portions of the spacer bars 22. This means that intermediate portions of said spacer bars lie approximately in the cylindrical plane of the cap side wall portions or flanges and the coverportion 18 may be applied without much friction, even though the fitis fairly close with respect to each end cap 24, until it reaches the corrugations 23 which, as will be seen, decrease in length from the center one toward those on either side thereof.

Upon reaching the corrugations, the interior surface of the core 19 of the roller coveris slightly expanded, or the corrugations sequentially bite thereinto .as the roller cover is gradually moved to normal position centered over the head.16. After being positioned, theroller cover 18 is thus tightly held in place by the frictional or biting engagement between the corrugations 23 and the interior surface of the core .19, whereby thereis not only during normal or conventional use, no undesired relative turning between the cover 18 and the roller head 16, but there is also no undesired longitudinal movement therebetween. At the same time the fit between the roller cover 18 and the end caps 24 is so close that no appreciable amount of paint, or other coating material, gets inside of the roller during use.

Although I have specified the roller parts, with the exception of the bearings, as being made of aluminum, I do not wish to be limited to this material, as other materials including steel, preferably the stainless variety to avoid rusting, may be employed. The rod 11 although desirably formed of steel, is not limited to this material. If steel is employed it is desirably plated or galvanized, if not of the non-rusting variety.

Having'now described this invention in detail in accordance with the requirements of the patent statutes, various changes and modifications will suggest themselves to those skilled in this art, and it is intended that such changes and modifications shall fall within the scope and spirit of the invention,'as defined in the following claims.
