    摘要： A FASTENER AND METHOD AND APPARATUS FOR PROTECTIVELY COATING THE WORKING SURFACES OF SAME WHEREIN THE METHOD COMPRISES THE STEP OF EXTRUDING A THIN METALLIC MATERIAL ONTO THE UNTHREADED SHANK PORTION OF A FASTENER IN INTIMATE CONTACT THEREWITH TO ENLARGE THE EFFECTIVE DIAMETER OF THE FASTENER WHILE PRODUCING AN ANTI-CORROSIVE MATERIAL BETWEEN THE MATERIAL OF THE FASTENER PROPER AND THE WORK PIECES WHICH THE FASTENER CONNECTS AFTER THE FASTENER IS INSTALLED. THE METHOD MAY ALSO INCLUDE PLATING COVERING THE SURFACE OF THE FASTENER WITH A MATERIAL WHICH ACTS AS A LUBRICANT DURING THE EXTRUSTION OF THE SURFACE MATERIAL ABOUT THE SHANK PORTION OF THE FASTENER, OR THE LUBRICATION OF THE DIES USED TO EXTRUDE THE MATERIAL ABOUT THE SHANK PORTION OF THE FASTENER PRIOR TO THE EXTRUSION OPERATION, OR LUBRICATING THE SURFACES OF THE METALLIC MATERIAL THAT IS TO BE EXTRUDED ONTO THE FASTENER PRIOR TO THE EXTRUDING OPERATION. THE APPARATUS OF THE INVENTION INCLUDES A DIE DEFINING A PASSAGE THERETHROUGH WHICH HAS AN EXTRUDING SECTION WITH A DIAMETER SLIGHTLY LARGER THAN THE DIAMETER OF THE FASTENER ONTO WHICH THE MATERIAL IS TO BE EXTRUDED, A MEANS FOR MAINTAINING THE FASTENER CENTERED WITHIN THE PASSAGE THROUGH THE DIE, MEANS FOR FORCING THE FASTENER AND THE MATERIAL TO BE EXTRUDED THEREON THROUGH THE EXTRUDING SECTION OF THE PASSAGE AND MEANS FOR EJECTING THE FASTENER FROM THE PASSAGE AFTER THE EXTRUDING OPERATION. ALTERNATIVELY, THE APPARATUS OF THE INVENTION MAY INCLUDE A DIE DEFINING A PASSAGE THERETHROUGH HAVING A DIAMETER SLIGHTLY LARGER THAN THE DIAMETER OF THE FASTENER ONTO WHICH THE MATERIAL IS TO BE FORMED. THE DIE FURTHER INCLUDES A SECOND PASSAGE IN COMMUNICATION WITH THE FIRST PASSAGE THROUGH WHICH THE MATERIAL TO BE COATED ON THE FASTENER IS INTRODUCED INTO THE FIRST PASSAGE AND MEANS FOR POSITIONING THE FASTENER IN THE FIRST PASSAGE AND CENTERING THE SAME WHILE THE MATERIAL IS FORCED FROM THE SECOND PASSAGE INTO THE FIRST PASSAGE AND AROUND THE FASTENER TO COAT THE SAME. THE FASTENER HAS A THIN SURFACE MATERIAL FORMED DIRECTLY ONTO THE UNTHREADED SHANK PORTION AND THE UNDERSIDE OF THE HEAD OF THE FASTENER. THE UNTHREADED SHANK PORTION MAY HAVE A REDUCED DIAMETER FROM THE NORMALLY STANDARD ONE, AND THE THIN COATING MATERIAL MAY ENLARGE THIS PORTION TO THE NORMAL STANDARD DIAMETER.

    摘要： Method and apparatus for severing thin walled tubing into selected lengths wherein the method includes circumferentially scoring the outside of the tubing at a predetermined point to produce a narrow weakened portion therearound and subsequently supporting the tubing internally while applying separating forces to the inside of the tubing at the weakened portion to sever the tubing at the weakened portion. The apparatus includes means for selectively measuring the length of the tubing to be severed and means for supporting the tubing internally while applying separation forces to the inside thereof at a circumferentially extending weakened portion to cause the same to sever at the weakened portion. The apparatus also includes means for producing a circumferentially extending weakened portion in the tubing.
