1 Claim. (oi. sl--5.5l

The present invention relates to a stippling device and more particularly for use in removinfl brush lines from freshly painted surfaces.

In the decoration of interior surfaces, such as 5 wells and ceilings in buildings and homes, it is often desirable to stipple the freshly painted surfaces in order to remove brush marks and smears that give an unsightly appearance to the completed work.- For this purpose heretofore, decorators have used a flat brush in various sizes having outwardly flared bristles.

the brush marks and leaving a dappled or spotted surface in its place.

This pounding method of stippling is used exclusively today by decorators in so far as applicant is aware. 'It is a slow method of work and uncleanly as in stippling adjacent wall boards, door casings and picture molds, the bristles come in contact with the woodwork causing paint smears and marks which must be cleaned up after the stippling is completed. No matter how accurate the worker may be this smearing lSbOllIld to occur with this pounding stippler. A further disadvantage is the fact that the bristles absorb the paint as does the ordinary paint brush tending to cause the bristles to stick together and making a splotchy surface unless the brush is frequently cleaned. Many years ago a revolving brush was suggested having long flexible bristles extending radially from a central core. Experiments with this type of brush show that it has the some disadvantages as the poundlngistippler. The flexible bristles spatter or kick the paint picked up by the bristle ends, smearing the'woodwork around which the stippling is being done. v'Illhe bristles tend to stick together causing the roller to slide, smearing the painted wall. This type of brush must also be cleaned frequently to prevent sticking of the bristles and the paint solvents and cleaning materials used for this purpose tend to break down the bristles. As these bristle brushes are expensive, the use of them adds considerable to 45 the cost of the work. Moreover, continuous pounding with the flat type of brush frequently opens cracks in the plaster that must be repaired. Various kinds of rotary bristle brushes have been tried. Short bristles or bristles placed in a 50 straight linetend to slide over the surface smearing the paint. Since plaster walls contain irregularities and slight depressions the short bristled brush frequently rolls over spots without touching or stippling them causing shiners and giving 55 the finished wall a dull app arance, Brushes This brush was pounded against the painted surface removin of the rotary bristle type have been used i'or graining metal surfaces in imitation of wood where a surface entirely different from a stippled hm? isdesired and may be satisfactory for this wor i A principal object oi this invention is to provide a stippler that is inexpensive to manufacture, is durable and one that may be renewed or easily cleaned as desired.

Another object of this invention is to provide 10 a stippler that will tend not to absorb paint and will not smear the painted surface nor spatter at on adjacent woodwork.

A further object of this invention is to provide a stippler that will stlpple uneven surfaces 15 and will save time and labor in per! the stippling operation.

Still other and further objects of my invention will be pointed out or indicated hereinafter or will be ant to one skilled in the art upon 20 an understanding of the invention or its employment in practice. c

For aiding in the disclosure oi the invention, there is shown in the accompany n drawing, forming a part of this speciilcation certain ar- 25 rangernents of mechanism by reference to which "the device is descrlbed.' It is to be that this description and dra are ented for purpose of illustration only and are not to be construed so as to limit the scope of the ap- 3o pended claim unnecessarily.

In the drawing:

Fig. l is a plan view of a roller stippler em.- bodying the present invention: and

Fig. 2 is a sectional view through the roller 35 stippler taken on the line 2-2 of, Fig. l.

In a preferred embodiment of this invention a cylindrical wooden or metal roller is used. This roller may be hollow i'or lightness if desired and in this case disks or end members are used for so the purpose of journaiing the roller within an operating handle. Over the rolleris'positioned a material having the characteristics of short fine hairs or napextending outwardly from a resilient body portion and forming a nap that apparently repels paint relative to normal brush bristles. When rotated over a plaster surface for 1 a stippling operation the resilient body portion,

under slight pressure, will permit the nap to enter depressions formed in the surface and prevent the possibility of shiners or a dull appearance to the finished wall. At the same time, the shortness and softness of the nap will prevent a skidding or smearing action of the stippier and its softness will do away with the normal tendency spatter paint over adjacent woodwork or the operator.

With reference to the embodiment shown in the drawing, the stippler includes a roller member l journaled at either end in a bifurcated supporting frame l2. An operating handle l4 extends outwardly from the frame l2 and may be rounded or otherwise formed to fit an operator's hand.

Over the roller member I0 is positioned a stip- I pllng means l6. This maybe fastened tothe roller in any suitable manner but preferably is removably aflixed thereto for the purposes hereinafter set forth.

The stippling means I6 preferably comprises a resilient or deformable base portion I! having outwardly extending flexible nap or closely as-- sociated hairs l8 that meet with and stipple the freshly painted walls. When this material is applied to the roller, the roller itself acts as a firm support behind the stippling means to give the proper amount of pressure and to prevent a skidding or sliding of the stippler such'as would be probable if only the nap surface as in the use of a bristle brush.

For this stippling means a carpeted material has been found to meet the requirements necessary for practical stippling. A carpet of the Brussels type affords a sufficiently soft base to permit the stippler to follow imperfections in the wall surface. Its short, soft, heavy nap will not absorb paint rapidly nor spatter the paint during a ,rolling operation.

Care should be taken in attaching the stippling cover member IE to the roller l0. A careless attachment will leave marks upon the walls which will be repeated at regular intervals depending upon the length of travel of the roller over the wall. If the roller is wooden, small headed, fine tacks 20 may be used adjacent the meeting edges of the covering material. These tacks should be countersunk within the base portion. I! of the covering so that the hop l8 will extend up around and over the tack heads concealing and enclosing the same. An adhesive may be applied to the itself engaged the wall 1 roller and the covering material carefully laid on over that so that the ends thereof are in juxtaposition and held fast in that position. A further method of attachment may be by sewing the two ends of the covering material together to form a seam 22 beneath the nap I 8. The last two attachments may be used on wooden or metal roll- The cover may be easily removed and replaced by using any of these attaching means.

.At the end of a days operation, or when saturated, the stippling means I 6 may be removed from the roller member ID and thrown away in the case of Brussels carpet, as the expense of the material is slight, and a new piece of material may be placed thereon for further use. This covering may be easily and quickly washed, however, and used many times. over. Various grades of coarse and fine. stippling may be done merely by varying and changing the grades of stippling or covering material.

Preferably the covering material l6 terminates evenly with the ends of the roller member l0 and the nap I8 is carried out to the edge of the base portion II. By forming the 'stippler in this manner it is possible to roll around door casings, baseboards and other framework without smearing them with paint.

For the purpose of exemplification,- one embodiment has been set forth herein. Structural modifications are possible without departing from the spirit of the invention. All such modifications are intended to come within the scope of the appended claim.

I claim:

In a roller for stippling walls, a hollow cylindrical body portion, disk-like end members closing the ends ,of said body portion, a bifurcated supporting frame journaled in said end members, a carpeted material including a resilient base portion'having a short relatively paintaepellent nap mounted on said body portion with its edges in meeting relationship, said edges being attached together and to said body portion through said base portion and beneath said nap.
