Leather head finishing system having plurality of apertures and angled shoe rails
View Patent ↗A single and multiple abrasive structure support system has a multiple support structure which facilitates use of snail lock and Frankfurt shoe adaptive support with a stepped surface which enables the snail lock adapter to enabling support of an abrasive structure beyond and at a distance clearance from Frankfurt shoe rails. The single abrasive structure support includes a snail lock. Both single and multiple abrasive structure support systems incorporate a pair of plates for absorbing force and energy, especially resulting from uneven surfaces being textured, such as stone.
1. An abrasive structure support comprising: a top plate; a bottom plate attached to the top plate and resiliently urged downwardly by the top plate, the bottom plate including a plurality of apertures; a plurality of snail lock adapters each having a body having a first end for threaded connection through its associated one of the plurality of apertures, the first end having a boss having a male thread fittable within and threadably engageable with its associated one of the plurality of apertures and a wide bore axial access opening extending through the boss and through a second end of the body, the second end of the body including a female snail lock connector for connection to another structure having a male snail lock connector; and pairs of angled shoe rails located on the bottom plate such that each of the plurality of apertures are in between each pair of angled shoe rails.
2. The plurality of snail lock adapters as recited in claim 1 wherein the body includes an outer periphery and a flat back surface between the boss of the first end of the body and the outer periphery.
3. The plurality of snail lock adapters as recited in claim 2 wherein the outer periphery includes a scalloped surface to facilitate manual grasping and turning of the snail lock adapter body to facilitate attachment of the first end.
4. The plurality of snail lock adapters as recited in claim 2 wherein the body of each of the snail lock adapters includes an extension step adjacent the boss and axially spaced from the flat back of the second side of the body to provide a clearance of the outer periphery in the direction of the first end of the body.
5. A multiple abrasive structure support as recited in claim 1 and wherein each of the plurality of apertures each carries threads for engagement with the first end of the body of an associated one of the plurality of snail lock adapters.
6. A multiple abrasive structure support as recited in claim 1 and wherein the top plate is attached to an ordinary tool holder to facilitate the use of the multiple abrasive structure support in automated surface treatment.
