First portable steam fire-engine—Brithwaite and Ericsson, England, 1830.

Vulcanizing of rubber—Charles Goodyear, United States, 1839.

Pneumatic tire—R. W. Thompson, England, 1845.

Time-lock for safes—Savage, United States, 1847.

Match-making machinery—A. L. Denison, United States, 1850.

Railway air-brake, use of air-pressure in applying brakes to the wheels of a car. A strong spring presses the brake against the wheels. Air acts against the spring and holds the brake away from the wheels. To apply the brake, air is allowed to escape, reducing the pressure and allowing the spring to act—George Westinghouse, United States, 1869.
