the Standardization of Small Tools and Machine ToolElements.The secondedition, known a s B5.9-1948, broadened the scope of the standard to include five sizes of Type L spindle noses, two smaller sizes of Types A, B and D spindle noses, namely, the in and in., and a new spindlenoselargerthanthe 20 in for Types A and B, nowknown a s the 28-in nose Similar changes were madein the American Standard for Chucks and Chuck Jaws (ASA B5.8) The third edition, known a s B5.9-1954, incorporated Unified Screw Threads jointly agreed uponby the American Standards Association, the British Standards Institution,and the Canadian Standards Association For thread designations and specifications see USA Standard for Unified and American Screw Threads (USAS Bl.1-1960) Other minor changes were also incorporated to clarify application of certain tolerances for plug gages, and a new paragraph was added to the text to provide balancing instructions In the fourth edition, approved by ASAon February 5, 1960 a s B5.9-1960, tolerances for length of pilot and depth of pilot holes for the Type A-1 and B-1 spindles were decreased slightly to reflect current actual practice in order to reduce the possibility of distorting the chuck or face plate when mounted on the spindle For the same reason, pilot bore diameters for some s i z e s of these chucks, and corresponding gage dimensions, were changed to reduce interference between chuck and spindle pilot diameters In addition, the method of dimensioning radial hole locations w a s changed to follow the practice set forth in American Drafting Standards Manual on Dimensioning and Notes (ASA Y14.5-1957) to insure interchangeability This Revision supersedes ASA B5.9-1960 Master ring gage inside diameters were slightly increased for some Types A, B and D spindle nose sizes, to coincide with the 1960 master plug gage change made to suit the increased chuck pilot diameters Counterbores for socketheadscrews were also changed to provide clearance for the “1960 Series” cap screws Tables showing assembly of face plates to Type A and B spindles were eliminated, and tables and pages renumbered Tables 35,36 and 37 in this edition, reflect the 1963 revision of Handbook H - Screw-thread Standards for Federal Services, and the recent USA Standard Gages and Gaging for Unified Screw Threads, USAS B U 1966, in changing “NOT GO threaded plug gages” to “HI thread plug gages” and “NOT GO thread ring gages” to “LO thread ring gages.” Following approval by the USA Standards Committee B5 and the sponsors, the revision w a s approved by the USA Standards Institute on April 21, 1967 USASTANDARD This USA Standard i s one of nearly 3000 standards approved a s American Standards by t h e American Standards Association On August 24, 1966, the ASA was reconstituted as the United States of America Standards Institute Standards approved a s American Standards are now designated USA Standards There i s no change in their
