Long-length Acme threads are used for controlled movements on machine tools,testing machines, jacks, aircraft flaps, and conveyors. Short-length threads are used on valve,stems, hose connectors, bonnets on pressure cylinders, steering mechanisms, and camera,lens movement.,The Standards Committee on the Standardization and Unification of Screw Threads, B 1,was organized in June 1921, with the Society of Automotive Engineers and the American,Society of Mechanical Engineers as joint sponsors under the procedure of the American,Standards Association (ASA), now the American National Standards Institute (ANSI). This,Committee was reorganized in May 1929, and its work was divided among five Subcommittees,as follows: No. 1 on Scope and Arrangement of American Standard; No. 2 on Terminology,and Form of Thread, Except Gages; No. 3 on Special Threads and Twelve Pitch Series,Except Gages; No. 4 on Acme Threads, Except Gages; and No. S on Screw Thread Gages.,National standardization of Acme screw threads in the United States was begun in 1932,when Subcommittee No. 4 on Acme Threads of Standards Committee BI held its first,meeting in New York. A report was presented on the types of Acme threads and the range,of sizes and pitches in use in this country. It was prepared by C. W. Bettcher with the,assistance of F. L. Woodcock. This report developed into a draft standard and was finally,approved as an American Standard with the designation ASA B 1.3- 1941. It contained a,section of introductory notes, and tables covering general purpose screws and general purpose,nuts, basic dimensions of general purpose Acme threads with special and……
