Title: Innovations by Robert L. Underberg
Introduction
Robert L. Underberg is an accomplished inventor based in Mequon, Wisconsin. He has made significant contributions to the field of optical instruments, holding two patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of Underberg's latest patents is the Level Transit. This telescope of the level-transit features two mirrors positioned at a 45-degree angle to the light path. A first mirror is securely fixed in the telescope housing, while the second mirror is designed for pendulating action, allowing the instrument to automatically compensate for deviations from level. When used as a transit, the telescope can tilt to measure vertical angles, locking the pendulum in a center position. Conversely, when used as a level, the telescope is locked against elevation or depression, enabling the pendulum to operate freely for automatic compensation. The pendulum weight includes an inverted conical member that interacts with a leaf spring, ensuring precise alignment and functionality.
Another notable invention is the Optical Sighting Instrument. This device utilizes the image of a floating bubble in a spirit level as a self-compensating index mark. It indicates a reference line of sight at a specific angle to the earth's normal surface, enhancing accuracy in various applications.
