US Patent 11619326 Anti-vibration mount

An anti-vibration mount has a base with a cavity. A core extends through the cavity and is coupled at its lower end to the base. A connector is threaded to the core and couples a part subject to vibration to the mount. The base cavity and the core define a receptacle extending around the core. A lower portion of the receptacle is substantially filled with lead. A bushing is carried in the upper portion of the receptacle around the core and bears on the lead. The upper surface of the bushing is elevated above the top surface of the base and bears the load of the part. A resilient body is carried around the connecter and, when the part is coupled to the mount, between the part and a connector head.
