RIVETING TOOL SHEATH AND METHOD TO REDUCE MARRING OF THE WORKPIECE

摘要

18 A riveting tool having a generally cylindrical tool head with a front fa ce for engaging the rivet head is modified by the addition of a sheath engaged over the tool head which is integrally molded from a plastics material. The sheath ha s a generally cylindrical sleeve portion engaged over a part of the cylindrical portion of the tool head and a front portion shaped to substantially fully cover and match the front face of the tool head. The sheath is shaped to provide a readily removable and replaceable friction fit on the tool head and has a thickness at the front portion which is sufficiently thin to allow forces to be communicated from the tool head t o the rivet head to effect driving of the rivet for attachment of the rivet to a materia l to be riveted and which is sufficiently thick to inhibit marring of the rivet and the material adjacent the rivet. The sheath has a peripheral rib at the edge for manually grasping and at least one raised projection on an inside surface thereof for engaging and providing a friction fit with the cylindrical portion of the tool head.
