Inventions - an automatic road roller, emergency exit on a bus and an "Expando" van.
No title. Transport devices and inventions.
Group of workers spread gravel on a road as a large roller is moved over it to flatten it down. The roller is pushed by hand. Another shot of the man pushing the roller. We are then shown a new invention - a motor roller which runs on petrol. C/U of the wheel of the roller. L/S of roller coming towards the camera. When the operator needs to go back the other way he simply throws over the roller's handle. The roller moves along by itself.
L/S of some kind of depot. A bus is driven past the camera. We then see 6 passengers inside the bus. The bus stops and one of the passengers opens the emergency exit on the upper deck. He folds down part of the bus and a lady steps out and onto the step ladder. The passengers then make their way out of the bus using this emergency exit.
Next up is an "Expando" van. The van is driven past the camera. The driver opens the door and turns a crank handle inside the van. The roof begins to lift automatically and the sides move sideways. "A self-contained mobile shop or office with ample room for shelves and showrooms." Two men sit inside the van smoking. They then climb out and the driver cranks the handle again to start the shrinking process. We see the sides move in and the roof lower. The man drives off.
