Title: Suspension system for bowl-type vibratory finishing machine

Abstract: A vibratory finishing machine has a bowl structure supported by shear-loaded elastomeric mounts, and a drive system for vibrating the bowl structure about a node or null point located along a vertical center axis of the bowl structure. Each of the elastomeric mounts has one portion secured to the bowl structure, and another portion secured to a base structure. The one and another portions define an axis of each mount. Certain of the mounts are arranged such that their axes intersect the center axis above the node or null point. Others of the mounts are arranged such that their axes intersect the center axis below the node or null point. Mounts arranged as described stabilize the location of the node or null point and thereby render the machine less sensitive to variations in bowl loading.
