From Gatling mechanisms to revolving gun chambers

The search for a higher rate of fire began with mechanically ambitious concepts inspired by the Gatling gun and revolver. That priority followed the Royal Navy's long institutional emphasis on firing faster than an opponent, including its experience at Trafalgar. Royal Navy proposals considered multiple barrels as well as rotating chambers loaded, cleaned, and checked at different positions. Scaling those arrangements to naval shells produced very large, heavy turrets and difficult sealing problems. Their weight and maintenance burden kept many ideas on paper, leading designers toward quicker and safer single-barrel breech operation.
