This is actually a really cool idea. I doubt it would be practical with the variety of modern body and wheel types, not to mention the fact that modern tires need air far less frequently, but it’s still nifty.
TIRE INFLATOR WORKS WITHOUT HUMAN AID
Putting air in the tires of your car should be a pleasure instead of a nuisance,according to Ellis E. White, of Los Angeles, who has just perfected an automatic tire inflator. To get air in the tires of his car, the driver need not get out from behind the wheel.
When his tires need air, he drives up a runway at the service station. He passes a box with a lever and a graduated scale, and with a touch of his hand he sets the lever to the number of pounds pressure he wishes in his tires.
At a certain point on the runway his wheels drop into a groove and close an electric contact, setting the intlator in action. Air nozzles advance from each side and press against special connections on the wheel’s hubs. Air flows into the tires. When the tire is full a bell rings and the air is shut off. To use the novel service, a car must have special air nipples that fit over the hub of his car’s wheels and have a pipe connection to the tire valve to complete the operation.
