0ct..10, 1933. E. HELMENSTEIN 1,930,358 APPARATUS FOR PAINTING CIRCULAR ORNAMENTS ON WALLS, CEILINGS, AND THE LIKE Filed Nov. 2, 1929 Patented Oct. 10, 1933 UNITED STATES APPARATUS FOR PAINTING CIRCULAR ORNAMENTS ON WALLS, CEILINGS, AND

THE LIKE Erwin Helmenstein, Dieringhausen, Germany Application November 2, 1929, Serial No. 404,443,

and in Germany November 18, 1928 3 Claims. (or. 33-27) This invention relates to an apparatus for painting circular ornaments on walls, ceilings and the like. Apparatus are known having a centre support fitted with an arm of adjustable radius on which a brush is mounted and adapted to be used like a compass for drawing circular ornaments.

The invention differs from the known constructions essentially in that the centre support is provided with two diametrically opposite arms which are not themselves adjustable but are formed as clamps with various holding points in which the brushes can be secured at various distances from the centre support. The provision of two arms presents the advantage that a counterbalancing is established which greatly facilitates the turning of the holder arms, further that if brushes are fitted at the same radius on the two arms for example for drawing a circular ornament only a half rotation is necessary and therefore the work can be carried out much quicker, and if brushes are clamped on the two arms at different radii diametrically opposite semi-circular ornaments can be drawn with a half rotation, and finally when carrying out work in different colours the brushes are situated at a sufficient distance apart to enable them to be easily dipped in the paints. The arrangement of a plurality of clamping points in the arms offers the advantage that the drawing of concentric circular ornaments can be effected in a single operation with a number of brushes. In a particularly practical manner a rubber suction disc is used for centering the rosette compass, which 1 disc adheres sufliciently tightly to the surface of the wall without damaging the same.

An embodiment of the invention is illustrated by way of example in the accompanying drawing in which:

Fig. 1 shows an elevation of the compass part section. V

Fig. 2 is a top plan view of the apparatus.

Fig. 3 shows a part elevation of the apparatus in use. I

On a rod (1 the outer end b of which is knurled, two arms 0, (1 each composed of two resilient wooden bars cooperating to hold one or more brushes and each provided with semi-circular notches e are rigidly clamped by means of screws f, this being made possible by a flattened portion g of the rod a. Clamping screws h serve for fastening brushes i, inserted in the openings e of the arms. The rod it carries also a head plate 10, by means of which it is guided in a bore 1 in an intermediate part m also accommodating a spring n, and held by a plate 0. The intermediate part m has an extension p, on which a rubber suction disc 4 is slipped, which disc rests against the wall 12 when the apparatus is in use. A bored handle 1' also slides on the rod a which handle serves solely for facilitating the manipulation of the apparatus and is prevented from slipping off by a rubber ring s slipped onto the rod a. The arms of the apparatus are divided along the line t so that it is only necessary to loosen two clamping screws in order to clamp the brushes in the arm 0, for example. Care must be'taken that, when the rubber disc q comes in contact with the wall 1', the brushes 1' are still a slight distance therefrom. Only when the rod a is pressed on in compressing the spring n, should the brushes touch the wall and, rod a being rotated at the same time by hand, draw the desired circular ornaments. Washers it serve to reduce the sur-' face friction between the individual parts.

I claim:

1. An implement for painting circular ornaments on walls, ceilings and other surfaces, comprisingin combination a rod, two arms each composed of two bars clamped on said rod and extending from opposite sides thereof, said bars adapted to cooperate to hold one or more brushes and to be rotated by turning said rod, and means on said rod for resiliently supporting said rod on the surface to be painted.

2. An auxiliary implement as specified in claim 1 in which the two arms are made of resilient material.

3. An implement as specified in claim 1 comprising in combination with the rod, an intermediate part surrounding the end of said rod, a head plate on said rod resiliently mounting it in said intermediate part, and a rubber suction disc on said intermediate part.
