Nov. 15, 1949 G. E. w. LEWIN SCARECROW Filed Dec. 15, 1947 ,J 2 i? N ATTORNEY FIG 4 INVENTOR. GUNNAR ERIK WERNER LEWIN 6 g w v 2 6 FIG- m 4. 7 2 F s Patented Nov. 15, 1949 OFFICE 1 SCARECROW Gunnar Erik Werner Lewin, Lidingo, near Stockholm, Sweden Application December 15, 1947, Serial No. 791,800 In Sweden May 6, 1947 6 Claims.

The present invention relates to a scarecrow consisting of a strip of metal foil or other suitable material.

The essential feature of the invention consists in that the strip is provided with bulged portions curved alternately in opposite faces of the strip.

By this construction the strip brings about a highly crackling sound when it is bent in one or the other direction. When the strip is suspended at one of its ends and is actuated by a gust of wind it is bent by the wind pressure, so that it forms a curve, by which the bulged portions are bent over from one face of the strip to its other face and effects a highly crackling sound. Thereupon the bulged portions tend to take again their original position, and as soon as the wind lessens the strip takes again its normal position, when the bulged portions again are bent over with said result of crackling sounds, etc.

In the accompanying drawing an embodiment of the invention is illustrated.

Figure 1 is a plan View of a strip according to the invention. Figure 2 shows to enlarged scale a section taken on the line I l-H of Figure 1. Figure 3 shows a longitudinal section to a further enlarged scale a bulged portion at the normal position of the strip. Figure 4 shows the same bulged portion of the strip as in Figure 3 in position after the strip has been curved by the wind. Figure 5 shows to enlarged scale a section taken on the line V-V' in Figure 1.

On the drawing l designates the bulged portions, 2 the material between said bulged portions in the longitudinal direction of the strip, 3 upper holes for suspending the strip, 4 lower holes for suspending the strip in reversed position, 1 longitudinal rows of the material between the bulges and 5 a layer of luminous material at the margins of the bulges in order to obtain a further scare for the animals.

As shown on the drawing the bulged portions 1 are elongated in the longitudinal direction of the strip and rounded at their ends. Further the drawing shows that the bulged portions I are positioned in rows in the longitudinal direction of the strip with the bulges in each row curved alternately to the bulgesin the adjacent row or rows.

The scarecrow according to the present invention may suitably be formed by a machine, in

2 which the strip by rolling is provided with harder compressed portions forming the bulges and less compressed portions forming the material 2 and 1 between the bulges.

What I claim is:

1. A device for producing sound comprising a strip of flexible, foil-like and resilient, metallic material provided with substantially parallel rows of elongated spaced depressed portions in each face of said strip, the depressed portions in adjacent rows being staggered and adjacent depressed portions in each row being oppositely depressed, agitation of said strip producing flexing of said depressed portions, thereby increasing the sound producing characteristics of said strip.

2. A device for producing sound comprising a strip of flexible, foil-like and resilient, metallic material provided with a plurality of depressed portions having a thickness less than that of the strip, said depressed portions being longitudinally and transversely spaced, agitation of said strip producing flexing of said depressed portions thereby increasing the sound producing characteristics of said strip.

3. A device for producing sound comprising a strip of flexible, foil-like and resilient, metallic material provided with longitudinally disposed rows of spaced depressed portions having a thickness less than that of the strip, the depressions in adjacent rows being staggered, agitation of said strip producing flexing of said depressed portions thereby increasing the sound producing characteristics of said strip.

4. A device for producing sound comprisin a strip of flexible, foil-like and resilient, metallic material provided with longitudinally disposed rows of elongated spaced depressed portions having a thickness less than that of the strip, the depressions in adjacent rows being staggered and adjacent depressions in each row being oppositely depressed, agitation of said strip producing flexing of said depressed portions thereby increasing the sound producing characteristics of said strip.

5. A device for producing sound comprising a strip of flexible, foil-like and resilient metallic material of such a guage that said strip if suspended may be fluttered by movement of air and may be readily distorted in any direction, said strip being provided with a plurality of depressed portions having a thickness less than that of the strip, said depressed portions being longitudinally and transversely spaced, agitation of said strip producing flexing of said depressed portions thereby increasing the sound producing characteristics of said strip.

6. A device for producing sound comprising a strip of flexible, foil-like and resilient metallic material of such a guage that said strip if suspended may be fluttered by movement of air and may be readily distorted in any direction, said strip being provided with longitudinally disposed rows of elongated spaced depressed portions having a thickness less than that of the strip, the depressions in adjacent rows being staggered and adjacent depressions in each row being oppositely depressed, agitation of said strip producing flexing of said depressed portions thereby increasing the sound producing characteristics of said strip.
