y Patentecl Aug. 12, 1930 JOHN RANGITSCE, OF ST. PAUL, -ilnxrxmsoTe` STIPLPLING DEVICE Application filed March 14, 1928. Serial No. 261520;

My invention relates to a new and useful device for stippling painted surfaces and the main object is to provide a simple, highly eficient and inexpensive device of said kind and the use 'of which as hereinafter described produces a multi-colored mottled paint sur- 'ace which makes, when so desired, an imitation marble efiect very natural in appear ance.

The device is fully disclosed in the following specification reference being had to the accompanying drawing in which,-

F ig. l is a top view of my improved stippling device. e i

Fig. 2 is a side elevation of Fig. 1. I

Fig. 3 is a bottom View of the :front part of my device.

Fig.4 is an approximately full size sectional detail at the center of one of the square formations of the fiexible part of the device about as on line4-4 in Fig. 3.

Referring to the drawing by reference letters A designates a preferably wooden block or back of my device being in an elongated quadrangular form and having one end tapered as B to about a ooint C said tapered fiparts being preferably less than 907 degrees e apart for the purpose of enabling the operator of my device to reach in and stipple painted areas in square corners.

The said block resembles and corresponds to the back or top of any flat type brush such as a scrubbing brush but in place of the bristles or similar means used on such brushes I secure a pad D of fiexible material such as rubber to one face of the block A said e pad corresponding in s-hape to the shape of of the block and being glued or otherwise secured thereto. From the lower side of side rubber pad extends a number of fiat fingers F spaced slightly from each other and ar-` ranged to form a series of squares throughout the quadrangular part of the pad and also in the center of the tapered ends but the fingers F at the latter tapered sides making of course triangular formations with relation to the adj acent inner fingers (see Fig. 3) The free end of each said finger is preferably reduced by mitering or cutting the corners angularly, as` F' in Fig. 4 and each finger extremity thus comprises a short transverse and central face F". The base of each finger is flared as at for strength'only but it will be readily understood that all the fingers are rigid enough to maintain their relative positions.

In the use of my device it must first be understood that a wall or other surface to be stippled is first covered with a coat of paint comprising the base color, and which is first allowed to dry thoroughly. This basecolor may be white, cream or gray, for example. Then a coat of black paint is applied over a predetermined area of said base oaint but immediately after this coat is on the operater takes my stippling device grasping the handle in the same manner as a scrub brush and applies it to said painted wet area with a series of pounding strokes, the fingers F thus being forcibly pressed against the wet paint and the said fingers yielding or twisting in various directions because of the pressure eX- erted and causing the wet paint to be spread in short streaks or dabs in various directions thus producing a stippled effect resembling when observed from a short distance an area of granite or marble according to the colors used. A third coat of paint of any mutable color may be applied to the second coat after the latter has been treated as above described to produce a three color stippled area. It is obvious that the stipnling treatment of the second coat of paint causes some of the first coatof paint to be eXposed and the third coat of paint likewise treated will eXpose parts of the first and second coats. After the last coat has been stippled and all the treated area is dry a suitable coating of varnish may be applied producing an efiect of highly polished stone.

I claim z- A stippling device comprising a base block of solid material, a stippling pad of fleXible material fixed on one face of said base block a series of flat fingers formed integral' with said stippling pad and extending therefrom at right angles, said fingers being elongated and arranged -in quadrangular formations With their adjacent parallel edges in spaced relation, said base block and stippling block tapered at one end of said fingers of the stippling block being arranged at right angles to each other except on the tapered part, the fingers of said tapered part extendng from the tapered edge to form tr'angular y arrangement with relaton to the fingers in wardly thereof, substantally as shown and described.

In testmony whereof I affix my signature.

JOHN RANGITSGH.
