Title: Innovations by Paul E Ritchey
Introduction
Paul E Ritchey is a notable inventor based in Madison, IN (US). He has made significant contributions to the field of construction machinery, particularly in the development of slip-form pavers. With a total of 3 patents to his name, Ritchey has demonstrated a commitment to enhancing the efficiency and effectiveness of concrete paving processes.
Latest Patents
One of Ritchey's latest patents is for a slip-form paver with a laterally moveable paving tool. This innovative design allows for the paving of concrete lanes in a manner similar to asphalt spreading. The paver's spreading and leveling mechanisms are strategically positioned behind the traction members, enabling the slab to be wider or offset from the tractor's distance. Additionally, the final paving tool can move laterally, independent of the tractor's steering, allowing for more precise turns. The elevation of this tool can also be adjusted using a string line, ensuring the desired pavement surface contour is achieved.
Another significant patent is the dowel bar placing attachment for slip-form pavers. This attachment features side plates and surface plates that engage the freshly formed concrete slab. The side plates can move laterally to accommodate any deviations in the slab's path, while the surface plate inclines upward to maintain the slab's contour during the insertion of dowel bars.
