ATTORNEYS Patented Oct. 6, 1953 PAINT APPLYING ROLLER Osborn P. Magoon, Alameda, Oalit, asslgnor to Leonard C. Davey, Alameda, Calif.

Application April 5, 1949, Serial No. 85,528 11 Claims. (01. 15-128) This invention relates to paint applying devices in general, and more specifically to a roller type paint applying device. a

In the applying of stipple enamel r fiat stipple paint, the customary procedure is to first apply the paint with a brush, and to then give a stipple finish to the paint so applied by running a carpetroller over the same. Such rollers, in themselves, are quite common, having a handle, and the outer surface of the roller being of carpet material having a pile to give the desired stipple finish when rolled over the paint.

The above procedure is time consuming and messy.

One of the objects of the present invention is I the provision of means for simultaneously applying the paint and performing the stippling operation, and. which operation is performed without requiring the step of repeatedly dipping a brush into a paint bucket or the like for transfer from the brush to the surface to be painted.

l-leretofore in the applying of ordinary fiat wall paint to ceilings and walls, the step of washing the dirt off the Walls and ceilings is many times omitted, since this step is relatively costly and is not always necessary. However, in applying the paint with a brush, the dirt usually becomes loosened and mixes withthe fresh paint, thereby advertsely affecting the color of the latter. The dragging of the bristles over the old surface is what causes the dirt to become loosened.

The present object of the invention is the provision of means for applying stipple or ordinary paint over a soiled or dirty surface without loosening the dirt, whereby the paint that is applied will remain clean and will have better adherence to the surface that is painted.

Another object of the invention is the provision of means for applying texture material to walls and ceilings in a more efficient and clean manner than heretofore. I

A still further object is the provision of a device for applying paint and the like to a surface, and which device includes a paint applying roller and means for quickly changing the paint applying surface material of the roller, either for replacement or for use of thedevice with a diiferent colored paint. An additional object is the provision of a device of the foregoing character that is easily cleaned of old paint whereby a different colored paint can be quickly and safely used, or the device can be stored in a clean condition for future use.

Another object is the provision of a simple, economical, pressure feed paint applying roller. in

which the paint is applied to the surface of the roller from a point outside the roller, and in which the paint is retained on the roller until transferredto the surface to be painted, thus making the painting operation a relatively clean and neat one.

Other objects and advantages will appear in the description and in the drawings.

In the drawings,

Fig. 1 is a part sectional and part elevational view of the paint applying device. The feed system is diagrammatically indicated.

Fig. 2 is a cross sctional view taken along line 2--2 of Fig. 1.

Fig. 3 is a cross sectional view similar to that of Fig. 2, but showing a slightly modified type of feed chamber for feeding relatively heavy plasterlike texture material to the roller.

In detail, the device comprises a shield I that is generally in the form of an elongated channel having corresponding sides 2, 3 that may be arcuately curved in cross sectional contour with their concave surfaces generally facing each other and in which shield said sides substantially follow a common cylindrical contour about a common axis.

' The bottom of said channel is formed to provide an elongated recess 4 extending longitudinally thereof, one side of which recess opens into the space between sides 2, 3 of the shield.

Recess 4 has a bottom 5, which bottom is formed with an opening 6 centrally between its ends. I The shield has opposite end walls 1, 8 that close the ends of the channel, said end walls being respectively slotted at 9 (Fig. 2) for receiving the ends of a shaft 10. I

The ends of said shaft may be formed with flat surfaces II on two opposite sides for sliding the ends of the shaft between the sides of the slots, so that the shaft will not rotate. The shaft itself may have heads I2 at said ends that may be integral withthe shaft, orthey may be threadedly connected with the latter as desired. One or more slightly outwardly projecting portions I3 on end walls I, 8 adjacent the sides of the slots 9 may serve to releasably hold the ends of the shaft in the slots, but upon exerting a predetermined force on the shaft in a direction outwardlyand longitudinally of the slots, the heads [2 will slip over said'projections and the shaft will be free from the shield. 'Any other suitable means may be provided for releasably securing the ends of the shaft to said end walls of the shield.

Bearings I5 are rotatable on said shaft at opposite ends of the latter. Each of said bearings includes a central hub I6 through which the shaft rotatably extends. Said hubs extend toward each other. A web I1 extends radially outwardly of each hub, and each web is formed with an annular flange I8 at its outer edge. Each flange I8 is turned slightly radially inwardly along its free edge, as indicatedat I 9 (Fig.1).

The flanges I8 of the bearings I5 are directed toward each other and extend over the opposite outer ends of a generally cylindrical core member 20. v

The core member is formed at its opposite ends with an annular radially outwardly directed.

recess in which the inturned edges'la of flanges I8 are adapted to fit. The core member is preferably of resilient spring lii'eta'l'and is split longitudinally along one side as at 2I so that they portions of the core extending away from the said. lit 2! a o o e. s de the eq Hi l Sprin apart, thereby yi debbc' oldin e en P tioos of the co e. thin the fl n es.

Different patterns may be formed on the surface material: in order" to produce different designs. on the wall uponpainting the same with a material that will hold such design without its flowing together.

"Secured withln'the recess 4? is an'elongated length'of tubing generally designated-'25; which, in' the presentin'stance is indicated as being square'orr'ectangular in cross sectional contour. The "end w'alls l. 8 may close the endsofthe tubing',"or separate plugs "ma be provided, if desired. Leakage past the ends of the tubing is not" harmful, "if" small, and may be beneficial. Side 28 of'said tubing extends across the sideof recess 1 at anoint about'wli'e'rethe said sideopens into the space between the sides 2, mime shield'lj and said side zfiiiis 'form ed with a longitudinally extndingrow of openings 21 that are directed "toward the roller that has the paint 'applying'1material thereon when the shaft carrying: the' roller is secured slots;

The 'e'ndsection 30 may be in two parts with part 32 having said exlternally'threaded endwhile the opposite end may be internally'threadedto threadedlyrecelve'one nd 'of a valve body" having a thumb controlled valve. 34 therein,

The opposite end of said valve body connects.

4 with said flexible conduit 3|. A button 36 is adapted to be pressed by the thumbs of the hand that folds the valve body.

Valve body 33 and section 3I together form the rigid handle adapted to be grasped by the hand of an operator for rolling the roller over the surface to be painted.

Paint or whatever similar material is to be applied, is conducted to the roller through conduit 3I' from a source 31 of said material under pres- 7 sure.

There is a space 38 between the side 26 and taller surface 23 which permits distribution of the paint along the full length of the roller. The sides 2, ma be'in substantially wiping engagefnent withthe external surface of the device. At least wiping engagement may be along the edges of the shield. A very slight clearance between the shield and roller permits the desired amount of paint to be drawn from the space. tit-by the. roller and then carried from withn the. shield to the; su ac o e painted.

The tubing 25 forms a chamber or compartment in which the, paint is distributed from end to end thereof for discharge of the paint material through openings 2,! into the carpet material of the roller, and the latter will carry the paint onto the wall where it will evenly deposit the same.

If stipple paint or. enamel is used, the same will be applied and stippled at. the same time since its viscosity is such thatit will retain the pattern impressed upon. it.

If flat ordinary paint is used, it is self levelling, and willnot retain the. stippled finish. The same. or a difierent cylinder may be used where the walls. are. merely. to. be. painted with flat oil or. water base paints.

Where relatively heavy texture. material is to be applied; a member. 45 (Fig. 3) may be sub.- stituted for: the. tubular member 25, and this member 45 isopen along the side facing outwardlyo'fthe shield so as to. offer. little. resistance to the'depositing ofthe texture material. onto the rollers. "In such form, there. may be slightly greater clearance between sides 2, 310i; theshield and the roller.

'In any event, handle Nils-secured. to the member 25, or {5 and not-directly tothe-shield; These members-26; '45 areusually of cast material, and are quite strong andr-igid; whereas, the shield may be of relatlvely light sheet-metal. Thusthe memhere 25 or 26 ;Will=furn. ish asupportfor the shield.

'The opposite sides of saidshield maybe forced lnwardly'ftoward each other and slightlyover the member 25, as indicated; at 4 7; for holding the member 25"(or 459 within the shield when the shleldf is separate from the handle.
