OFFICE BRUSH Alfred Renschin, Chicago, Ill. Application July 26, 1932. Serial No. 624,816 V 2 Claims. (01. 488) This invention relates to brushes for use in wiping painted surfaces to produce motley effects.

To enhance the appearance of painted surfaces, such as walls, ceilings, floors, and the like, they are usually either wiped for a motley effect, or else stippled. The motley finish is more popular, but also more difficult to produce than the stipple finish.

To produce a motley effect, the surface is first painted with a base coating which is permitted to thoroughly dry. A thin coating of a different color is then applied and, while the second coating is still wet, it is wiped deftly to remove the thin coating in places, thereby exposing portions of the base coating to produce the desired motley effects.

I-Ieretofore, the wiping of the top coating has been done with paper, old'rags, or sponges, all of which have proved very unsatisfactory because, with such wipers, it is impossible to obtain uniform strokes. Moreover, if paper or rags are used, they must be discarded and cannot be used for more than a few strokes. Sponges can be used repeatedly, but they can be properly cleaned only with great diiiiculty.

The main objects of this invention are to provide an improved form of brush for use in wiping the top coating; to provide a brush having improved blades forming wipers for producing the desired motley effects; to provide improved means for mounting the wiping blades on the back; and to provide a brush of this kind which is so constructed that it may be readily cleaned.

An illustrative embodiment of this invention is shown in the accompanying drawing, wherein Figure 1 is a perspective of one of the improved brushes, portions thereof being broken away.

Fig. 2 is a transverse section, taken on the line 2-2 of Fig. 1. V

Fig. 3, is. a fragmentary bottom plan of the brush.

Fig. 4 is a perspective of two of the rubber blades prior to insertion into the back.

In the specific form herein shown, the improved brush comprises a back which may be made of wood or any other suitable material and which includes a pair of panels 1 and 2. j

Formed in the panel 1, is a plurality of socket 3 forming seats for a plurality of flexible rubber wiping blades 4 which are of greater width than the diameter of the sockets. One or more ofthese wiping blades 4 are seated in each socket.

To insert the blades in the sockets, they are bent as shown in Fig. 4. The folded portion 5 is then drawn or pushed through the socket by any suitable means so as to cause the folded ends of the tufts to be compressed and project through the panel 1, as shown at the right end of Fig. 1. The projecting folds 5 are then severed with a knife so as to leave only a small portion of the blades projecting above the panel 1. A layer of rubber cement or other cementitious material 6 is then applied to the top surface of the panel 1 so as to embed and firmly cement all of the tufts together. By reason of the fact that the folds 5 are cut off, the cement reaches the interior of the.

tuft so as to properly cement the blades.

In addition to being secured by means of the cement, the tufts are secured by a frictional gripe ping action to the back because the sockets are considerably narrower than the blades, so that the latter are compressed in the sockets.

The panel 2 may be attached to the panel 1 in any suitable manner and it is recessed, as shown at 7 to house the cement.

As will be apparent, the outer substantially flat wiping edges of the blades are disposed at various different angles relative to one another but they are all disposed in substantially parallel relation to the plane of the back.

In operation, after the is applied and dried, the top coating is'then applied. While the'top coating is wet, it is wiped with the improved brush to produce the desired motley effects. Any desired design may be produced, depending upon the stroke used in wielding the brush.

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that details of the construction shown maybe altered without departing from the spirit of the invention as defined by the following claims.

I claim:

1. A brush for wiping painted surfaces to produce motley effects comprising a back having a plurality of sockets therein, and a corresponding plurality of tufts seated and secured in said sockets, each of said tufts comprising a plurality offlexible rubber blades the of which are'compressed and gripped in said sockets and the outer extremities of which form wiping edges of greater widththan-said sockets said sockets, and a layer of cementitious mate-' rialfilling said recess in which the inner projecting ends of said blades are embedded, the

outer endsof said blades forming wiping edges disposed substantially parallel to said back.
