Also known as the safety scoop and the car catcher, this device was designed to bring pedestrian deaths to a permanent halt. “This Roller Safety Device Sweeps Away Fallen Pedestrian,” declared a triumphant Modern Mechanix headline in 1931, elaborating that it “will literally sweep a fallen pedestrian before it and thus save him from being crushed to almost certain death beneath the heavy wheels.”
According to CityLab, the device featured a “grooved roller” attached to an extension beam on the car. Inactivated, it acted akin to a bumper. But when a pedestrian was in danger of getting hit, the driver needed only to pull a lever, and the grooved roller deployed to the ground.
“A flick of the lever, and the scoop has another mouthful,” the British Pathé narrator says, as the video shows a pedestrian catcher scooping up a jaywalker, demonstrated by one of the inventors. “When the scoop is open, a jaywalker simply can’t get run over, and sometimes that’s more than he deserves.”
The pedestrian catcher, however, was not as foolproof as it claimed. If the car was going too fast, or if the driver didn’t pull the lever fast enough, the pedestrian was in trouble.
