US4131079A — Wind rotated reflective scarecrow

Claim 1

Independent Claim 118 words

A scarecrow, comprising A. an elongated post for vertical mounting in a field; B. an elongated resilient wire having one end thereof extending axially from, and rotatably mounted on, one end of said post; C. at least one highly reflective disc rotatably suspended from the other end of said wire; D. the wire portion intermediate said ends forming an arc opening downwardly in response to its own weight and the weight of said disc to provide an oscillatory motion in response to slight forces on said other end, E. said wire and said disc both rotatably responsive to wind forces on said disc to thereby direct light reflected from said disc about a substantial area surrounding said post.

Claim 2

Dependent Claim 118 words

A scarecrow, comprising A. an elongated post for vertical mounting in a field; B. an elongated resilient wire having one end thereof extending axially from, and rotatably mounted on, one end of said post; C. at least one highly reflective disc rotatably suspended from the other end of said wire; D. the wire portion intermediate said ends forming an arc opening downwardly in response to its own weight and the weight of said disc to provide an oscillatory motion in response to slight forces on said other end, E. said wire and said disc both rotatably responsive to wind forces on said disc to thereby direct light reflected from said disc about a substantial area surrounding said post.

Claim 3

Dependent Claim 41 words

A scarecrow according to claim 1 (1) in which said disc is suspended from said wire by means of a yoke connected to said wire; and (2) which includes a plurality of highly force-responsive and light-reflective discs suspended from said yoke.

Claim 4

Dependent Claim 17 words

A scarecrow according to claim 2 in which said discs are each rotatably suspended from said yoke.

Claim 5

Dependent Claim 33 words

A scarecrow according to claim 3 in which said discs are suspended from said yoke by means of threads connecting the respective discs to the yoke and providing low torsional restraint to rotation.

Claim 6

Dependent Claim 24 words

A scarecrow according to claim 2 in which said yoke is suspended from said wire by a thread providing low torsional restraint to rotation.

Claim 7

Dependent Claim 27 words

A scarecrow according to claim 1 in which said disc comprises a generally circular thin disc coated with a material of high reflectivity on opposed faces thereof.

Claim 8

Dependent Claim 145 words

A scarecrow comprising A. an elongated post for placement in the ground in an area to be protected, B. an elongated resilient wire having a first end rotatably mounted in, and extending axially from, an upper end of said post and having a second end thereof extensible radially of said post and forming a downwardly opening arc highly responsive to vertical forces applied to said second end, C. a yoke rotatably mounted on said second end of said wire, D. a plurality of highly reflective discs rotatably suspended from said yoke and supported by said wire in cantilever fashion radially outwardly of said post, said discs being responsive to wind forces thereon to rotate about a plurality of generally vertical axes and oscillate about a plurality of horizontal axes to thereby cast light beams erratically in varying directions and at various distances from said post.

Claim 9

Dependent Claim 145 words

A scarecrow comprising A. an elongated post for placement in the ground in an area to be protected, B. an elongated resilient wire having a first end rotatably mounted in, and extending axially from, an upper end of said post and having a second end thereof extensible radially of said post and forming a downwardly opening arc highly responsive to vertical forces applied to said second end, C. a yoke rotatably mounted on said second end of said wire, D. a plurality of highly reflective discs rotatably suspended from said yoke and supported by said wire in cantilever fashion radially outwardly of said post, said discs being responsive to wind forces thereon to rotate about a plurality of generally vertical axes and oscillate about a plurality of horizontal axes to thereby cast light beams erratically in varying directions and at various distances from said post.

Claim 10

Dependent Claim 31 words

A scarecrow according to claim 7 in which said discs are connected to said yoke by means of threads of low torsional resistance to facilitate rotation in response to wind forces.

Claim 11

Dependent Claim 32 words

A scarecrow according to claim 8 in which said yoke is connected to said wire by means of a thread of low torsional resistance to facilitate rotation in response to wind forces.

Claim 12

Dependent Claim 39 words

A scarecrow according to claim 9 in which said discs comprise generally circular thin plates of plastic material, each in excess of four inches in diameter, and each coated on opposed faces thereof with a highly reflective metallic coating.
