Cyril and Louis Keller, the brothers who invented the world\u2019s first compact loader (later named the Bobcat skid-steer loader), have been selected as 2023 inductees for the National Inventors Hall of Fame (NIHF) in the USA.\u202fThe NIHF annually recognizes inventors, promotes creativity and advances the spirit of innovation and entrepreneurship.<\/p>\n How it all began<\/strong><\/p>\n In the 1950s, brothers Cyril and Louis operated a small machinist-blacksmith shop in Minnesota together, building and repairing machinery for local farmers. A farmer approached them with a need for a self-propelled loader light enough to be lifted to the second floor of a turkey barn and small enough to clean around the barn\u2019s upright poles. In response, in 1957, the Kellers built a three-wheeled loader with two drive wheels in front and a caster wheel in the rear \u2013 the predecessor to the modern skid-steer loader.<\/p>\n The loader came to the attention of Melroe Manufacturing Company (now Bobcat), which invited the Kellers to demonstrate their invention in their booth at the Minnesota State Fair in 1958. After a successful demonstration at the fair, the Melroe Manufacturing Company was awarded exclusive manufacturing rights to the machine on a royalty basis and hired the Keller brothers to refine the design and put the machine into production.<\/p>\n World\u2019s first true skid-steer loader<\/strong><\/p>\n To improve on the design of the loader, a second set of drive wheels was added to the back of the loader in 1960. With this four-wheel drive, the M400 became the world\u2019s first true skid-steer loader. \u2018Skid-steer\u2019 describes the unique steering system, which enables the machine to turn within its own length. Later, the Bobcat brand name was established because of the machine\u2019s toughness, quickness and agility.<\/p>\n Joe Keller, son of Louis, said, \u201cThe Bobcat loader has positively impacted the lives of thousands of employees who have worked for the company, dealers who sell the machines, and customers who use the equipment every day to build their livelihood. While we may not always realize its impact, it is an integral part of our everyday life\u2014from supporting farm operations that result in food on our tables to hauling materials around a jobsite building our homes and offices.\u201d<\/p>\n Sixty-five years later<\/strong><\/p>\n As Bobcat celebrates 65 years since the invention of the machine that created the compact equipment industry, it has continued to forge the future of the industry through innovation and forward-thinking.<\/p>\n Bobcat now offers more than 100 products in the compact, grounds maintenance and industrial equipment industries, and produces more than 150 families of attachments.<\/p>\n Other awarded inventors<\/strong><\/p>\n Other NIHF 2023 inductees include Rory Cooper, who invented wheelchair technology; Luis von Ahn, who co-created the website security program reCAPTCHA; Angela Hartley Brodie, who discovered and developed a class of drugs called Aromatase Inhibitors that stop the production of hormones that fuel the growth of cancer cells; and 14 other innovation pioneers. This year marks the 50th anniversary event of NIHF\u2019s founding in 1973, when Thomas Edison was the sole inductee.<\/p>\n Acknowledging the award on behalf of his father and uncle, Joe Keller<\/strong> said, \u201cThis recognition is a great honour to dad and Cyril\u2019s families, but it is not just for us. It is a recognition for all of the early and current Bobcat employees who have helped bring our little \u2018Keller loader\u2019 to be the Bobcat machine it is today. It has been a great honour to have had a front-row seat watching this invention revolutionize the way work gets done around the world.\u201d<\/p>\n For more information about Bobcat and Bobcat products, visit the website www.bobcat.com<\/a><\/p>\n \u00a0<\/u><\/p>\n","protected":false},"excerpt":{"rendered":"![\"\"](\"https:\/\/www.constructionplantworld.com\/news\/wp-content\/uploads\/2023\/01\/Cyril-Keller-200x300.jpg\")
