## Abstract

The invention is an ultrasonic whistle that screws onto the valve stem of a vehicle tire. A variety of alternative embodiments utilize a housing that screws onto the valve stem with variations as to how air travels across the whistle. As the vehicle's tires rotate, wind passes across the whistle, which in turn produces sound that is audible to animals and in turn alerts animals of the oncoming traffic.

## Claims

### Claim 1

A whistle that attaches to a valve stem of a tire comprising:
(a) a housing;
wherein the housing attaches to the valve stem of a tire by an attaching means;
wherein the attaching means involves an opening with internal threading that corresponds with the external threading of a valve stem of a tire;
(b) a side hole;
wherein the side hole is located along a surface of the housing;
wherein said side hole opens into a resonating chamber;
wherein the resonating chamber generates a whistle sound as air passes from the exterior of said housing and into the side hole upon the rotation of a tire; and wherein said whistle sound is an alarm to animals and people of an approaching vehicle.

### Claim 2 (depends on 1)

The ultrasonic whistle as described in claim 1 wherein the housing is made from a material comprising plastic, metal, wood, or a glass.

### Claim 3

A whistle that attaches to a valve stem of a tire comprising:
(a) a housing;
(b) a valve cap;
wherein the housing attaches to the valve cap by a fastening means;
wherein the valve cap attaches to the valve stem of a tire by an attaching means;
wherein the attaching means involves an opening with internal threading that corresponds with the external threading of a valve stem of a tire;
(c) a side hole;
wherein the side hole is located along a surface of the housing;
wherein said side hole opens into a resonating chamber;
wherein the resonating chamber generates a whistle sound as air passes from the exterior of said housing and into the side hole upon the rotation of a tire; and wherein said whistle sound is an alarm to animals and people of an approaching vehicle.

### Claim 4 (depends on 3)

The ultrasonic whistle as described in claim 3 wherein the housing and outer housing is made from a material comprising plastic, metal, wood, or a glass.
