Title: Innovations by Lawrence F. Iles
Introduction
Lawrence F. Iles is an accomplished inventor based in Madison, WI (US). He has made significant contributions to the field of muffler technology, holding a total of 2 patents. His innovative designs focus on improving sound attenuation and efficiency in exhaust systems.
Latest Patents
One of his latest patents is for a muffler construction that features improved sound attenuation characteristics. This design incorporates a tapered tubular metal screen within the outlet conduit of the muffler, which is aligned concentrically with the conduit’s axis. The closed end of the screen faces downstream with respect to gas flow, while the open end is attached to the conduit. This innovative screen effectively reduces sound levels without increasing the overall size or weight of the muffler.
Another notable patent by Iles is the particulate trap exhaust muffler, specifically designed for use with diesel engines. This muffler consists of a casing divided into an inlet chamber and an outlet chamber by an internal wall with multiple openings. Within the outlet chamber, a series of generally parallel tubes are mounted, with one end in the openings of the divider wall and the other end closed. Each tube features perforations along its length, allowing exhaust gas to flow into the tubes and through the perforations into the annular chambers formed by cylindrical particulate traps. This design not only decreases sound energy but also effectively traps and burns off particulate material before discharging the exhaust gas.
