In 1904 Loughead obtained a job as a mechanic for the White Steam Car Company in
San Francisco, where his brother Allan joined him in 1906. He claimed in his patent application that the force the rod applied was uneven and tended to shift between the wheels whenever an automobile moved. His design, contrariwise, involved a plunger mechanism that used fluid to apply force to the brakes, so that the force could not shift. He patented his new design in 1917. These
hydraulic brakes were adopted by
Duesenberg for their
1921 Model A. Loughead continued to revise the braking system and applied for 21 more patents for it, one of which was filed in Canada, between the years 1917 and 1924. In 1919, Malcolm and Allan were awarded the
Order of the Golden Crown by
King Albert of Belgium. In 1922 Loughead, who had recently moved to
Detroit, Michigan, filed for a patent for the flexible hose that streamed fluid into the hydraulic brake's plunger. It was reinforced with an incompressible tube inside of it so that changes in pressure would not cause it to expand outward and thereby impede the brake's operation. Because people kept mispronouncing Loughead as "log-head", Malcolm and Allan Loughead began to respell their surname as "Lockheed" and established the
Lockheed Aircraft Company in 1926 under the new spelling. Gold mining drew Lockheed to
Mokelumne Hill, California in 1930, where he invested in it; in 1942, however, the profits disappeared after the US government banned mining that did not contribute to the nation's effort in
World War II. ==Personal life==
