s Claims. (cl. 1st-121.3)

This invention relates to painting and decorating equipment, and has particular reference to a roller for spreading paint or other coating liquid, or semi liquid, or impressing orV stippling a design upon a at surface, and a pan or tray for applying such liquid to said roller.

The principal object of my invention, generally considered, is to provide painting equipment comprising an improved paint roller applicator, and a pan for spreading paint evenly overl the entire peripheral surface of` the roller, thereby avoidingundesired dripping during operation.

.Another object of my invention is to provide a paint roller comprising a'rod formed wtih a handle portion, an axle portionfdisposed at an angle thereto, a roller with a paint-absorbent cover mounted byV bearing members for rotation on said axle portion, cap members and a pair of resilient spacer bars bowed away from each other, the ends ofwhich are respectively secured to each other and to said cap members by said bearing members riveted thereover, said roller being internally engaged and resiliently held in place between its ends by said bowed spacer bars.

'A further object of my invention is to provide for use with a roller, such as above described, a metal pan for holding and applying paint to the absorbent cover of said roller, said pan comprising a bottom wall from which upstand side and end walls defining a reservoir, the side walls being spaced apart only slightly more than the length of the roller, the end walls being spaced a greater distance apart, and a device for elevating one end of the bottom wall above the other end, comprising a channel-shaped metal member with a web to stand upright at one end of said bottom wall, a relatively narrow flange to `directly underlie and connect with said wall, a relatively wide flange to engage the top of a support, and a relatively short flange extending directly from, and at right angles to, at least one of lthe web and the relatively wide flange, to form an element engageable with the bottom of theY support.

A still further object of my invention is to provide a paint roller with resilient members extending longitudinally thereof and arranged to frictionally engage its internal surface between its ends soas to hold it in position.

Other objects and advantages of the invention will become apparent as the description proceeds.

The invention to be subsequently described in detail involves structural refinements in a paint roller and accompanying pan or tray used for the application of paint or other coating liquid and/ or for impressing or stippling of a design upon a flat surface.

The roller of my invention isso constructed that the head may carry a removable pile roller cover. That is, the cover is easily removed for cleaning or discarding purposes.v The ease of replaceability, in combination with av spring tension feature hereinafter described, are important features of the invention.

Referring now to the drawings in detail, like parts being designated bylike'reference characters, and first consideringk the roller vdevice illustrated in Figs. l to 4, inclusive, there is showna rod 11, one end of the main or hand-adjacent portion oft-which is provided with a desirably wooden handle v12,01?. a shape oval-orA elliptical in section, asshown in Fig. 4, which comfortably lits the Y users hand, and from-which the rod 11 extends, aconvenient distance. It-is then bent at afright angle asv indicated at 13, ,again at a right angle to form a portion 14 parallel to the handle-connected portion, and then at a right angle to form a portion 15 parallel to the portion 12. This portion 15 provides an axle or journal on which is mounted a paint roller, generally designated 16. The axle portion is provided with a stop member or portion 20, which may be a hollow cylinder fitting the axle and fastenedthereta The member 20 desirably has an end flange facing the associated roller 16.

The paint roller 16 has a paint-dispersing hollow cylindrical cover portion 17 which may be formed of a convenient length and diameter, depending upon the area to be painted and the depth of the pile thereon. This cover portion 17 slides over and is resiliently held on the roller head 18. It is desirably formed as a core 19 covered with a fabric 21 possessing a pile of Dynel, nylon, Orlon, or similar synthetic or natural material which holds the desired amount of paint or other coating material. The depth of this pile may be short or long depending on .the type of coating material used.

The core `19 of the roller cover is absorb or be affected by paint, and will not disintegrate, crack, rust or dissolve throughout a normal life. A suitable material is that sold under the name Clevelite grade EE tubes. The fabric 21 is cut to a desired size and fastened to the core portion in any desired manner, as by 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 18 comprises a pair of oppositely arched spacer bars 22, desirably straight or flat transversely except for a central strengthening rib or channel, as illustrated, the ends of which are bent toward one another and connected to end caps 23 by means of bearing members 24. The bearing members are each desirably initially formed as hollow cylindrical portions 25 functioning also asY rivet Shanks, and a relatively-wide flange or Patented June 4, 1957 to more clearly illusfor holding a paint pan in posi-` desirably formed of l resin plastic-impregnated heavy paper tubing that will not head 26 at the outer end. They are assembled with the end caps 23 and the spacerV bars 22 by passing them through registering apertures thereof and having the ends of the cylindrical portions 25, opposite the flange portions 26,riveted over as indicated at27, thereby simultaneously connecting the spacer bars to one another and to the end caps. These spacer bars, before or after assembly, are desirably formed so that when stress-free or in normal position they are bowed away from each other to normal spacing distance, as shown in Figi. 3, so that they are compressed to an adjustable desired extent upon application of theroller member 16, thereby holding said roller member frictionally in position. This frictional holding effect is augmented by making each spacer bar wide enough as viewed in Figure 2, to subtend nearly 90, so that its side edges may bite into the inner surface of the hollow cylindrical paint-dispensing portion at four approximately evenly spaced positions around the periphery. The central strengthening rib of each bar 22 is desirably sufficiently shallow, as illustrated, to not interfere with such edge engagement.

The end caps 23, however, are formed to exert no pressure outwardly on the roller member, merely serving to prevent entry of paint thereinto, as guides for application of said roller member, and as protection for the enclosed ends of the spacer bars. The inner ends of said caps 23 are each formed with two laterally-spaced tongues desirably extending inwardly beyond the cap flange 51 into respective engagement wtih the spacer bars 22, as shown most clearly in Fig. 3. These spacer bars are desirably formed of resilient material, such as steel, preferably the stainless variety to avoid rusting, or spring brass. However, I do not wish to be limited to the material as other metals, including aluminum, may be employed. The end caps are desirably formed of aluminum for lightness, `as no resiliency thereof for holding the cover poition in place is relied on. The bearing members 24 are desirably formed of bronze or brass, and the rod 11 of steel, desirably plated or galvanized if not formed of a non-rusting material. The assembled roller 16 may be held in place on the axle portion 15 against the stop 20, by a screw 30 threaded into the end of said -axle portion.

The pan or tray 28, illustrated in Fig. 5, is formed of sheet metal, desirably of light material such as aluminum, and of a width to just accommodate the roller and its axle portion without unnecessary clearance. It is of a shape to provide a reservoir or well, to contain the paint or coating material, with its bottom extending from a deep portion 29 to a shallow portion 31.- The bottom wall at the shallow portion 31 is desirably formed with corrugations or embossments 32 of desired depth, serving the purpose of extruding excess amounts of coating material from the roller cover, and to better distribute said material thereover. provide an upstanding lip 33, with bifurcations defining a V-shaped notch of such size and acute angularity as to biftingly receive and frictionally grip the rod 11 (shown in dot-dash lines) of the roller 16 and adjustably hold it in a desired position on the sloping bottom of the tray, when' said roller is in a position of rest.

In order to perform the double function of holding the tray with the upper edges of its side walls horizontal and the bottom wall or floor sloping at a desired angle, when resting on a support such as a table, as well as for holding such a tray inv similar position from the top of a step la'd'der by having a portion engaging the under surface of the 'top step 50 thereof, I provide a foot or inclining device 34, Ialso 'shown separate from the pan 'in Fig. 6, U'shaped in cross-section. The foot 34 comprises an upper flange 3S, normally inclined like the bottom of the pan 28, aperturcd as indicated at 36, 37 and 38 to receive connecting means or bolts 39 which pass through corresponding apertures in the bottom of the tray 28 At the shallow end, I desirably o adjacent its shallow end, for holding said foot thereon. Associated with the bolts 39 may be washers or gaskets 40 to prevent leakage through the pan apertures, although it will be understood that these apertures are generally above a normal paint level, indicated at 41.

Depending from the flange 35 is a normally vertical web 42 and extending from the bottom edge thereof is a normally horizontal flange 43, desirably wider than the flange 35. For stiffening the angles between the web 42 and its flanges, the ends of all of said portions are desirably bent over to provide flanges 44, 45 and 46 at each end of the foot member. The flange 46 has a normally horizontal top edge. These flanges are desirably connected together, as by having overlapping portions spot welded, or by having the portions `at the meeting points upset inwardly, as indicated by the diagonal lines 47, and as shown in detail in Fig. 7 to take care of the excess material at such places. As an alternative, the flanges may be cut apart before bending the foot to U-shape, and a tab on one flange, formed to fit a slit in the adjacent flange, inserted in said slit and bent over, to thereby hold the parts rigidly in position, after bending to the illustrated shape.

Referring now to Fig. 8, there is shown an alternative form of foot'or support 34a comprising an upper flange 35a, normally sloping like the bottom of a pan to be supported, provided with apertures 36a, 37a and 38a like the foot of the preceding embodiment for connection with a pan, such as that designated 28, in a simliar manner. In the present embodiment however, the foot 34 although having a lower, relatively-wide normally-horizontal flange 43a, is not provided with end flanges, the

desired supporting function being taken care of by slit ting andV bending from the normally-vertical web 42Sl a flange 48, to normally-horizontal position, which leaves a corresponding aperture 49 in the web. In the present embodiment the upper surface of the flange 48 is disposed at the proper distance below the flange 35a, corresponding with the distance between the upper edge of the flanges 46 and the flange 3S of the preceding embodiment, so as to engage the under surface of a support, such as the top 50 of a step ladder, for holding a connected pan in desired position.

Although I have disclosed a special form of pan 28 for use in applying paint to a roller and a foot for holding the pan with its bottom inclined and the top edges of its side walls horizontal, yet as an alternative I may use such a foot with an ordinary baking pan, of the proper size for receiving the roller, but with rectangular, rather than tapering side walls, and end walls of equal depth. In such a case, however, the pan when in use would be desirably connected at one end to a foot of one of the forms disclosed, to have one end elevated above the other so as to provide the desired sloping bottom. Such a pan couldconveniently be one of the well-known commercial type in which the metal forming the walls and bottom is dimpled or rippled over its entire surface and tin plated, whereby' rusting would be avoided.

From the foregoing disclosure it will be seen that I have devised improved painting or coating apparatus, involving a paint roller having a head comprising spring members with sufficient resiliency to frictionally engage and hold the roller cover in desired position, while not interfering with ease of application and removal, mushroom type bearings being provided which perform the additional function of rivets holding the ends of the spring spacerV members to the desirably aluminum end caps which prevent entry of paint or coating material inside of the roller cover. For use with such a roller I provide a desirably light metal or aluminum tray with U-shaped means of sheet metal, light but strong enough to holdits bottom wall in a sloping position, either when resting on a flat surface such as a table, or when supported by engaging the under surface of the top of a step ladder.

Although preferred embodiments of my invention have been disclosed, it will be understood that further modiications are contemplated. It will also be understood that although I have mentioned tubes manufactured by the Cleveland Container Corp., of Cleveland, Ohio, under the trademark Clevelite grade EE, as desirable for use in the manufacture of my roller, I do not wish to be limited to the use of such material.
