Erastus Boise Kunkle, born on December 14th, 1836, learned the machine trade from his dad. Kunkle labored in a high pressure job before inventing the relief valve.
He worked in the locomotive shops for Pennsylvania Railroad where he invented a lock-up pop safety valve, designed to release steam pressure in locomotive engines. Boiler over pressure was a serious problem, yet relief valves were unheard of at the time.
Kunkle wanted to make his work site safer, protect his fellow man, and chase the American Dream. He was a curious inventor and diligent problem solver.
E.B. patented the pop safety valve invention in 1875.
Which of the following was not developed by Kunkle ?
1. Saftey valve
2. Water gauge
3. Egg beater
4. Steam condenser
>>>>> Answer– The steam condenser was not developed by Erastus B. Kunkle. In addition to a safer work environment, a lot of problem solving boiler solutions, we can thank E.B for the egg beater and subsequently the omelette.
The Fort Wayne Safety Valve Works, operated by E.B. Kunkle & Company grew and a 100 years later a modified version of the original invention was still in production and the eggbeater was a standard kitchen tool .
After Erastus passed away, the the firm was purchased in 1917 and renamed the Kunkle Valve Company.
In 1947 Kunkle Valve acquired the valve division of the Star Brass Manufacturing . The navy used Kunkle relief valves on ships and later on nuclear submarines.Valve shipments were over 1,000 a day in the 1970s.
In 1991, Kunkle Industries became a division of Anderson, Greenwood & Company. Anderson Greenwood (AGCO) is a current leader in pressure management valve solutions and has a unique back story all it’s own in aviation design.
