Abstract: A vibrating lap polishing system for flat items, comprising a polish pan with flexible bottom mounted on a base having three or more round-head bolts of equal height extending vertically above the base surface and positioned at one hundred twenty degree spacing on a circle about the base center; a center bolt attached to and extending below the pan center into a nut rotated by horizontally positioned gears, a center gear which rotates the nut and an outer meshed gear available from the outside work area to raise and lower the workpiece during operation. Means, which put no holes in the polish pan, are provided to pull the polish pan down onto the round-head bolts which create raised areas in the flexible pan-bottom. A flat-bottomed multi-item workpiece is circulated and rotated in an unsynchronized manner over the raised areas which creates a complete polish of the workpiece after sufficient cycles.

Abstract: The vibratory polisher system of this embodiment comprises six sub-systems: casting, polish pan assembly, base assembly, vibrating table assy (not a part of this invention), pan bracket assembly, casting circulator system, and horizontal slide assembly. The casting is comprised of an assembly of flat-bottomed rocks cemented into a flat-bottomed disc having a propulsion attachment. The casting circulates in a polish pan having a flexible bottom containing raised areas which put pressure on isolated areas of the casting bottom. There is an area at the pan center that can be raised by means of a gearing system to put pressure on the center area of the casting. The base assembly supports the polish pan and provides the bolt-heads that cause the raised areas in the polish pan. The base assembly also provides attachment points for the pan bracket assemblies which pull the polish pan down onto the bolt-heads thus causing the raised areas in the pan bottom.
