In 1893, an engineer broke from the Roots Blower Company and started the Connersville Blower Company. In the early 1900s Roots Blower Company invented a three-lobe blower to reduce pulses in the air flow. This engineering contribution would have its greatest impact nearly a century later as tri-lobe blowers were
