Title: Otto E. Kersten: Innovator in Hydraulic Technology
Introduction
Otto E. Kersten is a notable inventor based in Milwaukee, WI (US), recognized for his contributions to hydraulic technology. He holds 2 patents that showcase his innovative approach to engineering solutions.
Latest Patents
One of his latest patents is the Industrial Hydraulic Door Operator. This invention features a door operator equipped with a fluid drive motor and a manual override. The bidirectional hydraulic motor connects to a drive shaft through a power train that includes a shiftable quill-type manual clutch mechanism. This design allows for an alternate connection of the drive shaft to a manually-operated wheel. When the cable that shifts the clutch for manual drive is pulled, a switch disables the control for the hydraulic motor. Additionally, when the motor is not supplied with pressured fluid from the pump, a hydraulic brake engages the motor.
Another significant patent is the Ceiling Access Door Assembly. This assembly is designed for ceiling access and includes a frame that can be attached to the supports of the ceiling, mounted in a generally horizontal position. The door fits within the frame and has one edge hingedly connected to it. This hinge allows the door to swing between a closed position within the frame and a lowered open position. A constant-force return spring urges the door to the closed position, while an automatically engageable lock holds the door closed. The frame and door feature closely adjacent Z-shaped frame members, and the door is constructed from heat-resistant material, ensuring a fire-retardant design.
