Title: The Innovative Contributions of Leo W. Riegel
Introduction
Leo W. Riegel is a notable inventor based in Ankeny, Iowa. He has made significant contributions to the field of welding technology, holding a total of 3 patents. His work focuses on improving the efficiency and precision of welding processes.
Latest Patents
One of Riegel's latest patents is a method for welding rectangular tubes. This innovative approach involves notching the first tube on two sides to ensure that the top and bottom walls touch the rounded corner of the second tube, creating a weld-receiving groove. This design eliminates gaps between the abutted tubes, allowing for repeatable and well-defined welds. To simplify the welding process, a small tab is included in the notched end of the first tube, which fits into an oversized laser-cut slot in the second tube. This arrangement ensures precise alignment during welding.
Another significant patent by Riegel is a weld fixture mounting method. This invention provides a precise and fastenerless connection of a fixture to rotatable headstock and tailstock positioners. It utilizes a ball and socket arrangement for centering the fixture on the rotational axis, while a tapered roller and grooved rollers ensure linear and central location. This innovative support system allows for misalignment of the positioners without binding the fixture, enhancing the overall efficiency of the welding process.
