Abstract
Abstract An air scoop is positioned to receive and compress air in response to movement of a vehicle or its radiator-cooling fan. The compressed air is conducted to a whistle for producing sound at a frequency somewhat above human hearing range. The whistle is preferably provided with a dished reflector for forwardly beaming the sound. The reflector can optionally also be the air scoop.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
104 words
An accessory for a moving vehicle for scaring birds and/or animals away from the path of movement of said vehicle, said accessory comprising: an air scoop adapted to be fixed to said vehicle and positioned for collecting and speedwise proportionately compressing air in response to operation of said vehicle, whistle means connected to means constructed to forwardly emit sound at a frequency that is substantially above the audible range of the human ear, and means including a tube for operatively connecting said air scoop to said whistle means for continual sound emission therefrom and speedwise volumetrically in response to said operation of said vehicle.
Claim 2
Dependent Claim
104 words
An accessory for a moving vehicle for scaring birds and/or animals away from the path of movement of said vehicle, said accessory comprising: an air scoop adapted to be fixed to said vehicle and positioned for collecting and speedwise proportionately compressing air in response to operation of said vehicle, whistle means connected to means constructed to forwardly emit sound at a frequency that is substantially above the audible range of the human ear, and means including a tube for operatively connecting said air scoop to said whistle means for continual sound emission therefrom and speedwise volumetrically in response to said operation of said vehicle.
Claim 3
Dependent Claim
30 words
Structure according to claim 1, said whistle means comprising a whistle and said sound emitting means being a dished sound reflector connected to and positioned around and behind said whistle.
Claim 4
Dependent Claim
15 words
Structure according to claim 2, said air scoop and said reflector being the same element.
Claim 5
Dependent Claim
36 words
Structure according to claim 2, said air scoop being adapted for mounting behind the radiator fan of said vehicle for insuring operation of said pneumatic means when vehicle air-speed is low and/or for producing pulsed sound-emission.
Claim 6
Dependent Claim
40 words
Structure according to claim 2, said sound reflector having its open face covered by a flexible membrane for preventing its acting as an air scoop and producing sound-reducing back air-pressure, and for preventing whistle-clogging foreign matter from entering said reflector.
Claim 7
Dependent Claim
27 words
Structure according to claim 2, said sound reflector being paraboloidal and the sound-emitting aperture of said whistle being located close to the focal point of said reflector.
