James Gayley

Early life

Gayley was born on October 11, 1855, in Lock Haven, Pennsylvania, to Samuel and Agnes Gayley; Samuel was a Presbyterian minister who emigrated to the United States from Ireland at around 1840. Gayley spent much of his youth in West Nottingham, Maryland, where he attended West Nottingham Academy. He entered Lafayette College at age 16, where he graduated with a degree in mining engineering in 1876.

Career

Gayley spent much of his early career working at various iron and steel companies throughout the northern United States. He began his career working for the Crane Iron Company as a chemist, a position he held for three years with an annual salary of $500. After leaving he spent two and a half years as a superintendent at the Missouri Furnace Company. Gayley left this job to assume a management position at the E&G Brooke Iron Company in Birdsboro, where he worked for another three years.

In 1885, Gayley began working for Andrew Carnegie at the Edgar Thomson Steel Works in Braddock, where he incorporated fuel saving strategies and introduced new appliances to the mills which significantly altered the steel making process. One such invention incorporated charging bins which would mix, rather than heap, the various materials used in steel processing, allowing the ingredients to burn more evenly while using less fuel. Another was a compound condensing blowing engine to force more air into blast furnaces, enhancing combustion. Additionally, he installed the first mechanical ore loader and the vessels necessary for their use. These changes were described by the American Institute of Mining Engineers (AIME) as "bringing American blast-furnace practice up to a plane never before attained." For leading these improvements, Gayley was given the post of General Superintendent to the entire Edger Thomson plant, and by 1897 became the managing director of the Carnegie Steel Company.

One of the most important of Gayley's inventions was his device which prevented water vapor in the air from entering the furnace - a process he called the "dry-air blast". The dry air blast sought to prevent excess water vapor in the air from entering the furnace where pig iron was being produced. Humid air contains a certain amount of vapor which is detrimental to the quality of the pig iron produced; this is a particular problem in iron-producing centers in regions with high humidity. Gayley was the first to mount a condenser within the blast engine of a furnace which removed the moisture from the air. Using the dry-air blast, production yields increased by as much as 20%. After its inception, this process was described as one of the "greatest achievements in modern metallurgical chemistry" by members of the Perkin Medal committee.

Gayley was closely connected with Carnegie for much of his professional life, and was part of Carnegie's board of managers during the final years of Carnegie Steel. Due to his prolific involvement and as recognition of his services, Gayley was appointed as the company's first vice president when Carnegie Steel merged to form the United States Steel Corporation in 1901. At his new position, he oversaw the shipping and transportation of ore, in upwards of 30,000,000 tons annually. Gayley served in this capacity until his resignation in 1908 due to illness.

Memberships

Gayley became a member of the AIME in 1880. Between 1896 and 1905, he acquired the positions of manager, vice president and president successively. He then assumed the role as president of the Board of Directors from 1905 to 1911. Gayley stayed on the board as a director until 1913.

Gayley was a member of both the American and the British Iron and Steel Institute, and the Lafayette College Board of Trustees from 1892 until his death in 1920.
