US Patent 7377715 Tire deflation tool delivery device

This tire deflation tool deployment device is designed for use in situations where law enforcement officials desire to stop a vehicle in a chase situation. The device disclosed deposits a spiked deflation tool from beneath a command vehicle into the pathway of a target vehicle so as to puncture a tire of the target vehicle. The device includes a deflation tool storage and release housing. A fabric panel attached at one end to the housing has a second end wrapped about the tool and serves to lower the tool toward the pathway in an even and controlled manner before the tool leaves the fabric panel. From its release from the housing, movement and attitude of the tool are controlled by tether lines interconnecting the tool with the housing and payed out to a given extent limiting the distance the tool is towed behind the command vehicle.
