Latest Patents

One of Harding's latest patents is titled "Methods of making clutch driven plates." This patent describes a method of manufacturing clutch driven plates by sandwiching a castellated core plate between two clutch facing annuli. The thermosetting binder used in this process is substantially uncured, allowing for effective bonding once the assembly is clamped and heated. The friction material of the facing annuli is designed to push into the spaces between the castellations of the core plate, ensuring optimal performance without substantial bonding of the inner surfaces.

Another significant patent is "Friction materials and their manufacture." This invention focuses on a non-asbestos clutch facing that possesses an actual density allowing it to be permeable to air. The clutch facing is molded with short reinforcing fibers and is designed to maintain a density not greater than 90% of theoretical. The manufacturing technique involves preparing a pre-form, molding it to the desired density, and curing it under pressure to prevent further density changes.
