Schlage (pronounced /ˈʃleɪɡ/ SHLAYG) is a lock manufacturer founded in 1920 by Walter Schlage in San Francisco. Schlage also produces high-security key and cylinder lines, Primus, Everest and Everest Primus XP. Schlage is one of the most popular brands of consumer and commercial locks in the United States.
The Schlage Manufacturing Company was founded by inventor Walter Schlage in 1920 with the help of three businessmen who each contributed $10 to become equal partners. Walter Schlage had already secured several patents dating back to 1909, when he patented a doorknob that would also complete an electrical circuit so that, for instance, the lights would turn on when the door was opened. However, Schlage's key invention was the bored cylindrical lock, which evolved through several iterations, including a 1917 filing for a mortise mechanism which locked when the knob was tilted; two filings in 1920 (in April for a lock requiring one hole and a surface rabbet rather than a complex mortise pocket and October for a mortise with the lock mechanism activated by a button coaxial to the knob). This series would ultimately culminate in U.S. Patent 1,674,841, filed in 1923, which was sold commercially as the Schlage "A" series lock. Schlage would later make a 1925 filing for a push button cylindrical lock fusing the two 1920 patents with the 1923 patent.
Schlage's first shop was at 229 Minna Street, and he moved to 461 Bush Street, where many of his key patents were developed. The first factory (in 1923) was at 49 Shotwell Street. Because the bored cylindrical lock had a decided ease of installation advantage over the contemporary mortise lock, demand for the Schlage-designed lock rose and the company would purchase land in Visitacion Valley in 1925, which would eventually become the company's Bayshore factory and administration complex. Eight buildings were eventually erected at the Bayshore complex, the first two of which (the Old Office and Plant 1) were dedicated in a ceremony on June 25, 1926 attended by dignitaries including Mayor James "Sunny Jim" Rolph.
