Walter Schlage’s first invention, patented in 1909, was a door lock that had the ability to turn lights on and off. Around 1920, Mr. Schlage left his job at Western Electric and opened his own shop where he developed tools for manufacturing the first lock with a push-button device centered in the doorknob. In the early 1920s, Walter Schlage advanced the concept of a cylindrical pin-tumbler lock by placing a push-button locking mechanism between the two knobs. In 1923, Mr. Schlage moved his fledgling company to new quarters where he went into full-scale production of the push-button lock, which was destined to revolutionize the door lock industry. In 2013 Schlage - and the rest of the Ingersoll Rand Security Technologies - became part of 23 global brands to join forces under Allegion. Allegion is North America’s 1 manufacturer of security and safety products, security consulting and systems integration.
