Abstract
Abstract A bird frightener that may be removably disposed adjacent a tree or bush that bears fruit or berries that are attractive to birds as food. The bird frightener includes a pole that supports a prime mover on the upper end thereof, which prime mover rotates a number of spaced outwardly extending arms above the upper portion of the tree or bush. Each arm has at least one streamer thereon that waves as the arm rotates. Cam means operatively associated with the invention causes the arm to move upwardly and downwardly in what appears to an observer to be an erratic motion as the arms rotate. The upward and downward movement of the arms as they rotate, coupled with the waving streamers, is effective in frightening birds away from a tree or bush that has the invention mounted adjacent thereto, and as a result the fruit or berries on the tree or bush are not eaten by birds.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
238 words
A bird frightener that may be removably disposed adjacent a tree or bush that has fruit thereon to prevent the latter being eaten by birds, said bird frightener including: a. a pole that has first and second ends, said pole of such length that when said first end is embedded in ground adjacent said tree or bush that said pole extends upwardly through said foilage for said second second end to be disposed thereabove; b. a prime mover mounted on said second end, said prime mover including a driven member that is slowly rotated, said driven member having a cavity of noncircular transverse cross section extending downwardly therein; c. a first clutch member that includes a depending member of non-circular transverse cross section that slidably and snugly engages said cavity; d. a second clutch member axially aligned with said first clutch member and resting thereon; e. a head assembly secured to said second clutch member, said head assembly including a plurality of circumferentially spaced pivotally movable tubular members capable of being disposed in outwardly, upwardly and downwardly extending positions; f. a plurality of arms that extend outwardly, from said tubular members; g. a plurality of streamers secured to said arms; and h. cam means on which said tubular members rest when said head rotates, with said cam means imparting periodic up and down movement to said tubular members and arms as they rotate in said outwardly extending positions.
Claim 2
Dependent Claim
238 words
A bird frightener that may be removably disposed adjacent a tree or bush that has fruit thereon to prevent the latter being eaten by birds, said bird frightener including: a. a pole that has first and second ends, said pole of such length that when said first end is embedded in ground adjacent said tree or bush that said pole extends upwardly through said foilage for said second second end to be disposed thereabove; b. a prime mover mounted on said second end, said prime mover including a driven member that is slowly rotated, said driven member having a cavity of noncircular transverse cross section extending downwardly therein; c. a first clutch member that includes a depending member of non-circular transverse cross section that slidably and snugly engages said cavity; d. a second clutch member axially aligned with said first clutch member and resting thereon; e. a head assembly secured to said second clutch member, said head assembly including a plurality of circumferentially spaced pivotally movable tubular members capable of being disposed in outwardly, upwardly and downwardly extending positions; f. a plurality of arms that extend outwardly, from said tubular members; g. a plurality of streamers secured to said arms; and h. cam means on which said tubular members rest when said head rotates, with said cam means imparting periodic up and down movement to said tubular members and arms as they rotate in said outwardly extending positions.
Claim 3

38 words
A bird frightener as defined in claim 1 in which said first and second clutch members have first and second shallow engaging teeth thereon that permit said first clutch member to rotate relative to said second clutch member.
Claim 4
Dependent Claim
41 words
A bird frightener as defined in claim 1 which in addition includes: j. engageable means on said second clutch plate and engaging means on said head assembly that removably engage, to removably support said head assembly from said second clutch member.
Claim 5
Dependent Claim
72 words
A bird frightener as defined in claim 1 which in addition includes: i. a plate having a plurality of circumferentially spaced slots therein, and j. a plurality of rigid members that extend upwardly from said tubular vembers that may removably engage said slots in said plate, and said plate when said slots are so engaged serving to hold said tubular members and arms in outwardly extending positions in a common horizontal plane.
Claim 6
